    The invention relates to a main control valve with the features of claim 1.
    Furthermore, a fire extinguishing system with the features of claim 14 is to be specified.
    Main control valves of the type mentioned are already known and are shown for example in EP 2569058 B1. However, such valves have the problem that they offer only an opening or locking function and can not achieve multiple benefits. Thus, additional valves must be fitted to the check valve to make all the functions of a control of a fire extinguishing system can. These valves are then isolated practice over the fire extinguishing system distributed and not centralized and not easily accessible to the operator. Spatial distribution of the individual functions makes maintenance more difficult, operation becomes more complex, and the system generally becomes more susceptible to a variety of individual components. Furthermore, the operating status of the system for the user, for the
    Maintenance personnel or a person under review can not be recognized at a glance.
    It must be checked separately, different components, which are divided into the fire extinguishing system, to be able to survey an overall condition of the fire extinguishing system.
    The object of the invention is to avoid the disadvantages described above and to provide a comparison with the prior art improved main control valve and a comparison with the prior art improved fire extinguishing system.
    This is achieved in the main control valve according to the invention by the features of the characterizing part of claim 1.
    In the fire extinguishing system according to the invention this is achieved by the features of the characterizing part of claim 14.
    When the primary locking device is arranged in the valve block, adjustable between a blocking position and an open position, secondary locking device is connected, wherein in the open position of the secondary locking device, a flow of the control medium to the primary locking device, all components necessary for the user are arranged on a main control valve with a valve block, to check or change the operating status of the fire extinguishing system. Individual control units are not distributed over the entire fire extinguishing system at different locations. The user or operator of the fire extinguishing system will find a centralized main control valve to which all elements necessary for operation or checking are arranged. The primary locking device is in the ready state of the main control valve in an open position. Thus, in a secondary locking device also brought into the open position, the control medium is passed through the main control valve, in order subsequently to set the fire extinguishing system in motion. By a located in the blocking position primary locking device, the passage of the control medium is prevented by the main control valve. The secondary locking device is thus regarded as - preferably manually controlled - operating unit, which allows depending on the position of the primary locking device, the flow through the main control valve or not.
    It has proven to be particularly advantageous that at least one, preferably electrical or electronic, monitoring device for checking the position of the primary locking device and / or the secondary locking device is provided. Thus, the operating state of the main control valve can be detected centrally and transmitted for example via a network connection or other transmission medium to a monitoring system or control system. If the monitoring device should detect a problem on the main control valve or a faulty position of the primary locking device and / or the secondary locking device, this is communicated, for example in the form of a signal to a monitoring system and the user knows about the state of the fire extinguishing system. The monitoring device may, for example, also be connected to an alarm system which triggers an alarm in the event of a malfunction of the main control valve or a misalignment of the elements therein and immediately notifies the user that the fire extinguishing system is malfunctioning.
    If at least one optical display device is provided on the primary locking device and / or the secondary locking device, via which the blocking position and / or the open position of the primary locking device and / or the secondary locking device can be read, so the user or the maintenance personnel can monitor the condition of the system directly on the main control valve , For example, a color coding can be used to identify the state in which the primary locking device and / or the secondary locking device is located. Thus, z. B. on the colors red or green, the state of the main control valve are displayed. If the primary locking device in the open position, the secondary locking device in the blocking position, the fire extinguishing system is in the operating position. This means that in case of fire, the main control valve is ready. The open position of the primary locking device and the locking position of the secondary locking device are displayed, for example, by green color codes. The primary locking device is in the blocking position, this is represented by a red optical display device. So even with an open position of the secondary locking device. Instead of colors, of course, symbols or texts can be used to z. B. color-blind people also to allow easy reading of the display device.
    When the primary locking device and / or the secondary locking device has at least one control disk with at least one link control, which is operatively connected to the at least one monitoring device, wherein upon adjustment of the primary locking device and / or the secondary locking device between the blocking position and the open position, the position of the control disk and thus the Position of the primary locking device and / or the
    Secondary locking device by the at least one monitoring device can be detected, it is possible to control the operating state of the
    Primary locking device and / or the secondary locking device to detect. The control disk can also include the optical display device (color coding red / green, symbols or text box) in order to read the operating state of the primary locking device and / or the secondary locking device directly.
    Thus, it is for example possible to install a window on the cover over the control disk, the control disk has the color coding or another type of display device, which can be seen depending on the operating state of the primary locking device and / or the secondary locking device in the window of the cover. Control discs with slide control are generally difficult to manipulate or influenced. These are also behind a cover, which prevents manipulation of the control disc or slide control.
    The cover may be formed in the form of a housing which extends at least in sections over the main control valve.
    If the at least one monitoring device is formed by at least one pushbutton with at least one electrical contact, wherein the pushbutton is engaged with the slide control of the control disk or can be brought into engagement depending on the position of the control disk, then the position of the control disk and the scenery control queried directly. Due to the interaction between the button and the control disk and the gate control manipulation of the monitoring device is excluded. Using different positions along the link control, different operating states can be queried via different buttons. In addition, a position can be determined by the detection over several buttons via different positions or sections along the slide control, which allows a redundant query. For example, as soon as a button has a defect, the signal can be detected by another button that engages with another area of the gate control.
    If the at least one link control of the primary locking device at least one primary release section - preferably two primary release sections - and the at least one link control of the secondary locking device at least one secondary triggering section for detecting the position of the respective control disk and thus the primary locking device and the
    Having secondary locking device, all necessary operating conditions or positions of the primary and secondary locking device are determined. Thus, it can be read via the slide control and the sections arranged thereon, whether the main control valve is in the standby position or in another position. The position of the primary locking device can be detected independently of the position of the secondary locking device via the individual sections.
    If the primary locking device and / or the secondary locking device each have a securing device, wherein upon actuation of the primary locking device and / or the secondary locking device, the securing device is irreversibly destroyed, whereby a manipulation of the primary locking device and / or the secondary locking device is displayed by a destroyed security device so recognizes the user at first glance, that has been manipulated on the main control valve. The securing device can be produced, for example, by a sealed wire loop which is connected on the one hand to the primary locking device and / or the secondary locking device and on the other hand to the housing or another component of the main control valve. If the primary locking device and / or the secondary locking device is triggered, the seal or the loop breaks and a manipulation is thus displayed. It can be seen whether the main control valve is on standby or not.
    If the primary locking device and / or the secondary locking device are formed by a gas-tight check valve, in particular in the form of a gas-tight ball valve, then a creeping escape of the control medium is excluded. When using a ball valve, it is also easy for the user or the maintenance personnel to operate the primary locking device and / or the secondary locking device, especially when a
    Hand lever is located on it.
    As particularly advantageous, it has been found that in the
    Secondary blocking device located blocking position is bypassed by a switching valve, wherein upon actuation of the switching valve, the control medium is guided past the located in the blocking position secondary locking device and a release of the blocking medium from the valve block can be achieved. Thus, the standby main control valve by switching the switching valve that
    Give control medium to the other components of the fire extinguishing system and achieve extinguishment of the fire. If the switching valve is adjustable by an electromagnet between the blocking position and the open position, the opening of the switching valve can be done electrically. For example, a signal goes from one
    Control device, which has detected a fire via a detection device. This signal is then passed to the electromagnet, which is the
    Switching valve moves in the open position. Thus, the passage for the
    Control medium created and the control medium is at the
    Secondary locking device passed. In this case, subsequently introduced via externally arranged elements, the introduction of the extinguishing medium to the desired
    Scored areas. In case of a defect on the electromagnet, on the switching valve, the
    Detecting device, the control device or in the wiring, however, can be triggered by opening the secondary locking device manually deleting the fire. Thus, the secondary locking device can be overridden by the switching valve or the switching valve by the secondary locking device.
    When the primary locking device and the secondary locking device each have a
    Manual operation - in particular in the form of a lever - have for manual operation and via the manual operation, the primary locking device and / or the
    Secondary locking device in independence of the state of the state
    Switching valve or the control of the electromagnet can be actuated, it can be done in the case of - as described above defect - at the fire extinguishing system, a manual release of the fire extinguishing system. The hand control is easy to recognize for the user. In addition, the display device shows in which operating state the main control valve is located. After the manual release of the primary locking device and / or the secondary locking device, the change of the operating state is represented by the display device. Furthermore, this is represented by the destroyed safety device. In addition, the monitoring device detects the change of the operating state. The
    Primary locking device has the advantage that it can be brought from the open position to the blocking position, for example, to shut off the control medium applied there to be able to wait or check the fire extinguishing system. During verification work, for example, the entire system must be checked for leaks. The system is thus "pushed off". For this purpose, pressure is built up in the individual lines and elements in order to be able to detect leaks. For this purpose, it is very advantageous if you can complete the system via a primary locking device completely.
    If the valve block comprises at least the following inputs and / or outputs: - Control pressure input to the control medium input to the valve block, - Control pressure control to the uncontrolled output of the control medium from the valve manifold regardless of the position of the switching valve, primary locking device and secondary locking device, - at least one Leakage output to the output of the control medium from the valve block at primary locking device and secondary locking device and / or switching valve in the open position, and - at least one quick opening output to the output of the control medium from the valve block at primary locking device and / or switching valve in the open position and secondary locking device in blocking position, a compact main control valve is generated which all
    Includes switch inputs and outputs to enable the function to be used in a fire extinguishing system.
    If a detection device is provided, which detects at least one sensor fire and / or smoke, wherein in case of fire via a device connected to the detection device control device, the secondary locking device located in the blocking position is bypassed by the control medium, preferably by a switching valve on it is passed and exits the valve block, so a fire extinguishing system with a main control valve is created, which acts in the function simple and clear. The maintenance and operation of the fire extinguishing system is also simplified.
    In the event of a defect in the switching valve, the control device, the sensor, the detection device or the wiring, a manual release may take place.
    When in a standby state of the fire extinguishing system the
    Primary locking device in the open position and the secondary locking device dwells in the blocking position, wherein no control medium from the main control valve to the environment or another arranged on the main control valve or connected device, preferably for dispensing or preparation of the extinguishing medium device is discharged, so is at a main control valve of Standby state of the fire extinguishing system made. It is not necessary to operate different valves. All elements necessary for the operation or maintenance of the fire extinguishing system are arranged on a main control valve centrally on the fire extinguishing system. It can be seen in which position the primary locking device and / or
    Secondary locking device are located. This can also be detected by the position of the arranged on the primary locking device and the secondary locking device levers, which act as a manual operation. If these levers are in a disparate shape relative to one another, the user or the maintenance personnel can draw conclusions as to the position of the primary or secondary locking device due to the position of the levers. This is supported by the display device.
    If in the case of malfunction of the main control valve manual opening of the main control valve is feasible, the control medium from the main control valve to the environment or another arranged on the main control valve or device connected, preferably for dispensing or
    Preparation of the extinguishing medium provided device is submitted and is subsequently discharged from the fire extinguishing system, the extinguishing medium to the environment, a functioning fire extinguishing system is made. In the case of a malfunction can be expected nevertheless with a deletion of the fire. This must be triggered manually in this case. The centralization of all controls on a main control valve or juxtaposed several main control valves in the case of a multi-zone extinguishing system ensures that the operator or the maintenance personnel at a glance receives the overview of the function of the fire extinguishing system.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings. Show:

    Fig. 8b Detailed view of main control valves strung together.
    Fig. 1 shows the main control valve 1 in a schematic representation. The housing 2, shown in dotted line, thereby comprises the following inputs and outputs:
    Input of the control pressure E1 to the input of the control medium 105 in the valve block 2. Via a channel, the control medium 105 is then to the port
    Output control pressure E2 passed. There, the control medium 105 may be unregulated, for example, to another valve block or another
    Main control valve 1 will be passed. This is for example at a
    Series connection of main control valves 1 the case. Thus, it is possible to supply at least one further main control valve 1 via the connection E2. At the channel between the input control pressure E1 and output control pressure E2 is a supply channel to the switching valve 30, which communicates with an electromagnet 12 and can be operated by this. Also connected to the channel between the input control pressure E1 and the output control pressure E2 is the secondary check valve 4. This is in the
    Standby position in the locked state. The switching valve 30 is as 2/2
    Way solenoid valve formed. Spring loaded is this in the
    Standby position, in which no passage from the terminals E1, E2 to the
    Primary check valve 3 is carried out and thus not to the leakage outputs A1, A2 and the at least one quick-opening A3.
    If the primary locking device 3 is arranged in the valve block 2, adjustable between a blocking position and an open position, secondary locking device 4 is connected, wherein in the open position of the secondary locking device 4, a flow of the control medium 105 to the primary locking device 3.
    When switching by the electromagnet 12, the switching valve 30 is in the
    Passage position, wherein flow from the input of the control medium 105 of the terminal E1 to the leakage outputs A1, A2 and the
    Fast opening exit A3 takes place. This happens, for example, in the case of
    Brandes. If the solenoid 12 or the switching valve 30 should not work, the control medium 105 can be discharged via the secondary locking device 4. Thus, the switching valve 30 is overdriven. For decompression of the system, a check valve is installed in the basic position (closed position of the switching valve 30), which allows evacuation of the control medium in the system or control pressure. The control medium 105 and the control pressure generated thereby is thus not locked in the system in the closed position or blocking position of the switching valve 30. Through this evacuation of the
    Control pressure is ensured that maintenance personnel, for example, when opening lines at the leakage ports A1, A2 or A3 quick-opening outputs can not be injured by caged control pressure. For this purpose, however, the control medium 105 must first be terminated by the connections input control pressure E1 or output control pressure E2. Thus, the control pressure can escape from the system, even if the secondary locking device 3 dwells in the locked state.
    Upon activation of the fire extinguishing system, the solenoid valve 12 of the fire alarm or. Extinguishing control center - the control device 103 - electrically controlled. The electrovalve 12 opens the switching valve 30 and the pending control pressure in the form of the control medium 105 of, for example, 70 bar activates all the downstream elements.
    In order to prevent an unwanted triggering of the fire extinguishing system 100 in the event of maintenance or flammable work in the extinguishing area, the fire extinguishing system 100, as well as each extinguishing area must be separately blocked by the primary locking device 3. In the event that the fire extinguishing system does not trigger automatically via the solenoid 12, which can happen in the event of a defect in the solenoid 12, no fire detection, or a fault in the control device 103, the activation of the fire extinguishing system can also be done manually via the secondary locking device 4.
    Depending on the type of installation (single or multi-zone extinguishing system) and applicable fire extinguishing system directive, main control valve 1 will be used for various control options.
    The responsibility of each connection is as follows:
    Input control pressure E1: input control pressure 70 bar at 20 ° C outside temperature and 80 bar at 60 ° C outside temperature (or 10 bar +/- 1 bar to control the downstream range valves 109) and / or alarm devices 106 (shown in Figure 7 and 8a).
    The leakage outlet A1 is responsible for the output to the leakage valve.
    The leakage output A2 is responsible for the output of the control pressure to the time delay by means of time delay device 107 or can be passed to the range valves 109th
    The quick-open output A3 is responsible for the output of the control medium 105 to the alarm device 106, it can be connected to the quick-opening output A1, a quick-opening valve with a time delay.
    The output control pressure E2 is responsible for the connection of other main control valves in multi-range extinguishing systems (series connection).
    Fig. 2 shows the main control valve 1. Located on the valve block 2 is ever a manual control 13 for the underlying primary locking devices 3 and secondary locking devices 4 (not visible in Figure 2). The manual control 13, in the form of a lever, is connected to a housing 14 by means of a securing device 16. If the manual controls 13 are moved, then the securing devices 16 are destroyed. A manipulation of the main control valve 1 is thus made apparent. In addition, the hand controls 13 each have a display device 6. This can give both color and symbols or text conclusions about the position of the manual control 13. The
    Standby position of the main control valve 1 can be represented for example by two green color markings. If one of the manual controls 13 is not in its respective readiness position, this can be displayed via a red marking or a corresponding text passage or a corresponding symbol. The user or the maintenance personnel is thus informed immediately in which position the main shut-off valve 1 is located. In addition, the position of the manual control 13 - in the form of levers - also allows a logical inference to the position of the main stop valve. 1
    Fig. 3 shows the main stop valve 1 with the control discs 7 at the respective
    Primary locking device 3 or secondary locking device 4. The primary and
    Secondary locking device 3, 4 is formed by a ball valve. At this
    Ball valve are each the control discs 7, which a
    Slotted control 8 have. In the case of the secondary locking device 4 is a
    Secondary release portion S1 arranged on the slide control 8. In case of
    Primary locking device 3 become two independent
    Primary release sections P1, P2 arranged on the slide control 8 of the control disk 7. Thus, depending on the change in the position of the manual control 13, the respective primary release section P1, P2 of the primary locking device 3 or also the respective secondary release section on the slide control 8 of FIG
    Control disk 7 on the secondary locking device. 4
    4 shows the main control valve 1 with the control disks 7 described above, the gate controls 8 arranged thereon with the respective primary triggering section P1, P2 and secondary triggering section S1 shown in FIG.
    Along the curve control 8 or the triggering sections P1, P2, S1, at least one button 9 engages in the surface of the slide control 8. So can the
    Position of the primary locking device 3 and the secondary locking device 4 are determined via the buttons 9. At the button 9 is at least one electrical contact 10, the position of the control discs 7 and slide control 8 to the
    Control device 103 passes. Thus, the control device 103 monitors the
    Main control valve 1. The primary locking device 3 includes two
    Primary release sections P1, P2, not only the open position, but also the
    To detect locking position. The secondary locking device 4 in this embodiment has a secondary release section S1. However, it can also be provided several sections. Whether the solenoid valve 12 has triggered or not is monitored by the tripping monitor 15.
    The main shut-off valve 1 is the primary control and operating element of
    Fire extinguishing system and includes the visual display of the valve control in the form of the display device 6, including the explanation of the displayed on it
    Color codes or symbols on a label which is attached to the main control valve 1 or in the vicinity of the main control valve 1. Furthermore, the main control valve 1 comprises a remote monitoring in the form of the monitoring device 5. The integrated leakage valve A1 is a safety device and prevents unwanted activation of the fire extinguishing system due to leaks in the system. This means that no pressure can build up in the system due to internal leaks or leaks that are not visible from the outside. This leakage valve A1 is open up to an overpressure of about 3 bar system pressure, closes only when the main shut-off valve when the switching valve 30 or the secondary locking device 4. In the flooding and the abrupt increase in pressure associated with the leakage valve A1 is closed. All electronic components, such as electrical contacts 10 are possible in addition to a standard version in an EX protected version.
    Fig. 5 shows the main stop valve 1 in the standby position. In this case, the hand controls 13 designed as levers point away from each other. Both display devices 6 indicate the readiness of the main shut-off valve 1. The monitoring device 5 engages with the buttons 9 in the respective triggering section P1, P2, S1 of the control discs 7 shown in FIG. In the standby position, the electromagnet 12 can be actuated in order to dispense the control medium 105 (not visible in FIG. 5) from the main control valve 1.
    Fig. 6a shows how the secondary locking device 4 was opened manually. This occurs, for example, in the event of a defect in the electromagnet 12 or another circumstance, as already described above. Thus, that is through the
    Primary locking device 3 released control medium 105 also released by the manually opened, located in the open position, secondary locking device 4 and can cause the triggering of the fire extinguishing system 100 subsequently. In this case, the primary control device 3 indicates via its display device 6 that this is in the open position, for example, by a green mark and the secondary locking device 4 indicates that it is in an open position. This is likewise done via the display device 6 - for example via a red mark. In parallel, this is monitored by the monitoring device 5.
    Fig. 6b shows a locked main control valve 1. It was the
    Secondary locking device 4 brought into the blocking position, which is also shown on the display device 6 accordingly. The primary locking device 3 is in the closed state - the blocking position. This is also indicated by the display device 6. As can be seen in Figures 5, 6a, 6b, it is not possible, both hand controls 13 - designed as a lever - to each other so that an illogical or unnecessary circuit or position of the primary locking device 3 or secondary locking device 4 results. The executed as a lever manual operations 13 would collide and be mutually in the way. For example, it is not possible for the
    Primary locking device is in an open position, while the secondary locking device is in a closed or locked position. The main control valve 1 combines all the functions required by applicable directives and standards as well as valuable additional functions for the operator or user or the maintenance personnel.
    Fig. 7 shows a fire extinguishing system 100 (single-zone extinguishing system) with a main control valve 1. This is acted upon by a pilot bottle with the control medium 105 therein. Thus, a control unit is formed by the pilot bottle and the main shut-off valve 1. This system section is always acted upon in operation with a control pressure of, for example, 70 bar at 20 ° C.
    The unit is with wires, for example, 6mm copper wires, and
    Fittings, for example, Ermetoverschraubungen, and a pressure gauge for reading the control pressure generated from the control medium 105 connected to each other. The control medium 105 passes at the input control pressure E1 in the main control valve 1 and subsequently at an opening of the main stop valve 1 from the leakage outlet A2 out. Thus, the pneumatic time delay device 107 is driven. Subsequently, it comes to the control of the fire extinguishing system 100 and the delivery of the in the
    Bottles located extinguishing medium 104. This takes place, for example, time-delayed. In addition, an alarm is issued via an alarm device 106. The system is controlled by a control device 103, the one
    Detection device 101 includes and detected by a sensor 102 a fire. If the solenoid valve 12, for example fail or the control via the control device 103 does not work, the fire extinguishing system can be activated by means of the manual release via the secondary locking device 4.
    In the standby mode or the standby position, the primary locking device 3 is opened and the manual release via the secondary locking device 4 is closed. In case of blockage of the system, the primary locking device 3 is closed.
    In the case of a manual release of the system, the secondary locking device 4 is opened. An actuation of both locking devices 3, 4 is not provided, and not effective. For this reason, the device is designed so that both levers would collide with each other, as soon as they are brought into an illogical position.
    FIG. 8 a shows a fire extinguishing system 100 as a multi-zone extinguishing system with two different extinguishing areas. For the smaller extinguishing area, fewer extinguishing agents 104 may be assigned to contained bottles than to the larger extinguishing area. This multi-range extinguishing system also has a control device 103, detection device 101 and a sensor 102. Depending on the extinguishing region, a plurality of control devices 103 with a plurality of control devices 103 may also be provided
    Detecting devices 101 and a plurality of sensors 102 may be provided. These control the electromagnets 12 of the responsible for the respective area
    Main stop valve 1 on.
    In Fig. 8b, the individual main stop valves 1 a
    Multi-zone extinguishing system shown in detail. The first main control valve 1a on the left in the row takes over the role as a control unit. This is with the
    Control medium 105 connected via a pressure gauge and controls when activated, for example, the pneumatic time delay device 107. The
    Main control valves 1b, 1c thus receive the control pressure generated from the
    Control medium 105 reduced to, for example, 8 +/- 1 bar from the
    Time delay device 107. The main control valves 1b, 1c are used for
    Driving the two shown in Fig. 8a area valves 109 on the
    Quick-opening outputs A2 (see Figure 1) and the alarm device 106 via the quick opening outlet A3 (see Figure 1) in the respective erase area. The main check valves 1d, 1e contain the control pressure generated by the control medium 105 in a non-reduced form, but delayed by a certain time factor, for example 30 sec. The control pressure is also passed from the time delay device 107 to the input control pressure E1 (see Fig. 1). This serves to control the quick-opening valves at the quick-opening outputs A3 of the respective main control valves 1 and thus to release the extinguishing medium 104 in the respective extinguishing area. The extinguishing medium has a maximum pressure of 60 bar at 20 ° C. In the event that due to the applicable standards and guidelines no
    Time delay is required, the pressure reduction of the
