    Hydraulic Water Supply Enhance Device
    Applications:
    The invention is used in fixed installed systems for fire-protection with Nozzle water-sprays with water droplets with droplet sizes Dv90 larger than 0,001m and/or low pressure Water Mist Nozzle water-mist sprays with water-droplets with droplet sizes Dv90 less than 0,001m with Nozzle inlet water pressures of 16 bars and less.
    Known methods & technologies:
    A known method is to direct hydraulically connect nozzle pipe systems of water spray and low pressure water mist systems directly to town mains water supply.
    A problem with this known technology is that town-mains water supplies often have insufficient water pressure capacities for the water spray and water mist nozzles to produce the water sprays or the water-mist sprays intended.
    The above mentioned problem is known to be tried helped with an electrical powered pump-system, which is hydraulically installed down-stream the Townmains water supply outlet and up-stream the inlet to the nozzle pipe system. When one or more nozzle pipe-system nozzles operate and distributes water sprays the water pressure will drop in the nozzle pipe system. The pressure drop activates a pressure transducer, which provides an electrically signal to a pumpcontrol system, which activates the pump-system to deliver a water flow to the nozzle pipe system, which is higher than the town-mains water supply pressure.
    Problems with the introduction of electrical pump-system are the extra costs an introduction of an additional electrical pump technology involves in purchasingand installation- and connection- and maintenance-cost, as well as the extra
    DK 2017 70097 A1 complexity an additional technology introduces and the additional space and maintenance required to the pump-system.
    What the invention achieves:
    The invention is a technology simple hydraulically device, which is simple to manufacture and install and maintain,, which with an energy supply only from the water supply connection to the fire protection system enhances the water pressure on water flows to fixed installed nozzle pipes for water spray and / or water mist systems for fire protection.

    Figure 4 shows an example on a Low Pressure Water Mist Nozzle spray system and / or a sprinkler system (2) with normally closed automatic operated nozzles (5), which is hydraulically connected to a water supply system (1) with capacity to deliver a water flow which is sufficient at water pressure which is insufficient for open spray nozzles (5) in the nozzle pipe system (4) to distribute water spray or water mist sprays as intended, where an example on the invention (9) is hydraulically installed between the water supply outlet (7) and the nozzle pipe system inlet (3).

    Figure shows an example on the invention in the form of a unit devise.
    Figure 8 shows the control of the invention shown in figure 7.
    Description of designs and performances:
    Figure 1: Shows an example on a water spray and / or water mist fire protection system (2) which includes a fixed installed wet pipe nozzle pipe system (4) with normally closed water spray or low pressure Water Mist nozzles (5) and a water supply inlet port (3), which is hydraulically connected to a water supply system (1) outlet port (7), for example a connection to a Town mains water supply system (1).
    The system in Figure 1 functions with: When the stop valve (8) is opened a water flow is allow to flow from town mains water supply (1) through the town mains outlet port (7) and the nozzle system inlet port (3) to fill the Nozzle pipe system (4), with water at a Nozzle system water pressure (Ps) which acts on the closed spray nozzles (5) and which is identical to town mains water pressure (Pp). When in case of fire one or multiple spray nozzles operates to open, the water supply system (2) automatically delivers a sufficient supply of water flow at sufficient water pressure, typically (2 to 12) bar to the activated spray nozzles, which makes the activated nozzles cable of supply sufficient sprays for the system to fight the fire.
    Figure 2: Shows an example on a water spray and / or a water mist fire protection system (2) which includes a fixed installed dry pipe nozzle pipe system (4) with open water spray nozzles or low pressure water mist nozzles (5) and a normally closed stop or control valve (8) and a nozzle system pipe inlet port (3), which is hydraulically connected to an outlet port (7) of a water supply system (1), for example a town mains water supply system.
    DK 2017 70097 A1
    The system in figure 2 functions with: When the stop or control valve (8) opens, water flows from the water supply system (1) through the water supply systems outlet port (7), through the inlet port (3) and through the open stop valve or control valve (8) into the dry nozzle pipe system (4) and a water flow of sufficient size and pressure flows through the pipes (4)to the open spray nozzles (5) from where water sprays or water mist sprays of water mist sprays sufficient to fight fires are sprayed.
    Figure 3 shows an example on a Low Pressure Water Mist Nozzle spray system and / or a sprinkler system (2) with normally closed automatic operated nozzles (5), which is hydraulically connected to a water supply system (1) for example a town mains system with sufficient flow capacity and insufficient water pressure capacities for sufficient supply of water to the water spray nozzle or water mist spray nozzles when activated to open, and with an electrical powered pump system (9) which includes an electrical water pressure pump (10) and a pump control system with a water pressure switch system (11) connected to a power control (12) which are connected to a power supply system (13), and which is hydraulically installed between the water supply system (1), and the normally closed wet pipe nozzle pipe system (4).
    The system in figure 3 functions with: When the fire protection system stands in standby the water supply system (1) keeps the connected hydraulic pump (10) and the connected wet pipe normally closed Nozzle system (4) pressurized with water at the water pressure of the water supply system. The standby by system pressure (Ps) keeps a normally closed water pressure switch (11) deactivated. When in case of fire one or multiple closed spray nozzles operates, water flows from the Nozzle pipe system (4), causing the water pressure (Ps) in the wet nozzle pipe system (4) to drop. This causes the pressure switch (11) the activate a signal to the control system (12), which activates the pump (10) to raise the water supply pressure (Pp) from the water supply system (1) to the nozzle pipe
    DK 2017 70097 A1 system to make the water pressure in the nozzle pipe system (4) (Ps) be larger than the water supply pressure (Pp), PS > Pp, which enables the activated spray nozzles to distribute the intended water and water mist sprays.
    Figure 4 shows an example on a low pressure water mist nozzle spray and / or a water spray system (2), which contains a wet pipe Nozzle pipe system with normally closed water spray sprinkler nozzles and / or low pressure water mist nozzles (5), with an example of the invention (10) hydraulically installed on the inlet port (3) of the wet pipe normally closed and automatic operated spray nozzle system pipes (4), and where an outlet port (7) of a water supply system (1), which has a larger water flow capacity and an insufficient water pressure capacity are hydraulically connected to the inlet port of the invented device.
    The system, which is described in figure 4 functions with: After the system has been installed water from the water supply system (1) leaks through the pump (9) inside the invented device's (10) and flows through the low capacity check valve (14) into the closed nozzle pipe system (4) where the standby water pressure (Ps) becomes the same as the standby pressure (Pp) of the water supply system (1) which often is a town mains water supply system. When one or multiple spray nozzles (5) due to fire operate, the water pressure (Ps) in the wet pipe nozzle pipe system (4) decreases. This operates a hydraulic switch-valve (11) to open and allow the pilot control water of a normally closed control valve on the invented device (10) to drain, which allows the control valve (15) to open and water to flow from the water supply system (1) through the control valve to the power Turbine (12) on the invented device and direct to drain (13), which makes the turbine deliver torque force on a driving shaft with mechanical connection to a water pump (9) located in the invented device. The pump flow will here after builds up a water pressure (Ps) in the nozzle pipe system (4), which is sufficient for the open spray nozzles to deliver water sprays or water mist sprays which effetely fight the fire.

    Figure 5 shows an example on a known low pressure water mist nozzle spray and / or a water spray system (2), which contains a dry pipe Nozzle pipe system with open water spray nozzles and / or low pressure water mist nozzles (5) and a stop valve or a control valve (8) and a pump system (10), which is hydraulically installed between the inlet port (3) to the dry pipe nozzle system (4), and the outlet port (7) from a water supply system (1), which has a water flow capacity of sufficient flow capacity and insufficient water pressure capacity for a direct supply of water to the open spray nozzle system.
    The systems which figure 5 shows functions in event of a fire with: The stop or control valve (8) is being opened and the pump (10) is activated to start pumping water from the water supply system (1) into the open spray nozzle system pipes (4). The pump water flow builds up a water pressure in the nozzle pipe system (Ps) which is higher than the water pressure of the water supply system (1) and sufficient for the water spray nozzles and or the water mist nozzles (5) to deliver an effective spray for fighting the fire.
    Figure 6 shows an example on a low pressure water mist or water spray fire protection system which consist of a dry pipe nozzle pipe system (2)) applying open spray nozzles (5) with a normally closed stop valve or a control valve (14), which is hydraulically located at the pipe system (4) and a water supply system (1) having more than sufficient water flow capacity for the spray nozzle pipe system (4), but with insufficient water pressure capacity to supply spray nozzles with water to distribute effective sprays for providing an intended system firefighting ability, and an example of a device of the invention hydraulically located with its inlet port attached to the outlet port (7) of the water supply system (1) and with the inventions outlet port hydraulically attached to the inlet port (3) to the nozzle pipe system (4).
    The fire protection system example in figure 6 shows performs with: water leaks from the water supply system (1) through the pump (9) of the invented device
    DK 2017 70097 A1 (10) into the system pipe located between the invented device outlet and the closed stop-valve or control- valve, building up a water pressure similar to the water pressure (Pp) on the water supply system, in the event of fire the stop- or control- valve (14) is opened and the water pressure in the system pipe between the invented device's outlet and the satop- valve or control valve is released. The water pressure drop at the device outlet causes through a pilot water pressure pipe a hydraulic normally closed pilot water switch (11) to open and drain the pilot water of the control valve (15) which opens the valve and pressurized water flows from the water supply system (1) to a power turbine (12) on the invented device (10) to drive the turbine, which through a mechanical driving shaft drives the pump on the invented device(10) to supply a pumped water flow of water delivered from the water supply system (1) through the nozzle pipe inlet (3) and the open stop- or control valve (14) into the nozzle pipe system (14) where the water flow from the invented device builds-up a water pressure in the nozzle pipe system (Rs) which are larger than the water pressure (Pp) from the water supply system (1) and which allows the spray nozzles to deliver water sprays and or water mist sprays sufficient to fight the fire.
    Figure shows an example on the invention in the form of a hydraulic pressure amplify devise with a water inlet port (1) and a water outlet port (2), and a water drain port (9), which are characterized by the water inlet port (1) being an opening into a chamber (3), which have hydraulically connections to a pump (4) and a body (5), and where the hydraulically outlet of the body is hydraulically connected to a power turbine (6) having it's driving shaft (7) mechanical connected to the driving shaft (8) of the pump (4).
    Referring to figure 7 the function of the invented device is: The device inlet (1) is connected to a pressure water flow. The water flows through the device water inlet (1) into a chamber (3) where the water flow is divided into two water flows, one flow to a pump (4), the other flow flows through the cavity if a body (5) to
    DK 2017 70097 A1 drive a turbine (6), which via a shaft connection (7) & (8) delivers torque power to the pump (4) which deliver a flow of water at the devise outlet (2) which are higher than the water supply pressure acting on the devise inlet (1). The water flow from the power turbine flows to drain from the devise drain outlet (9).
    Figure 8 show an example on the invented device shown on figure 7 with control, which is characterized with the body (5) is a control valve with it's water inlet connected to the chamber (3) and it's outlet port hydraulically connected to the inlet port of the power turbine (3), and where the pilot water control chamber (10) of the control valve (5) is hydraulically connected to a hydraulic switch with hydraulically connection pipe (11) to the device inlet chamber (3), and hydraulically connection pipe (12) to the device outlet port (2), and a hydraulic connection to drain (13)
    The invention example figure 8 describes functions as the invention examples described in figure (4), (6) and (7), with the device inlet port (1) connected to the water supply outlet port, water flows into the inlet chamber (3), where the supply flow is divided in to a water flow to the hydraulically connected pump arrangement (4) and into the water inlet of the control valve (5) and from here through the valve stem into a pilot chamber cavity (9) which is located at the rear end of the control valve, and which is sealed with a hydraulic valve switch (10) which stays closed when the water inlet pressure on the device are equal or less than the device outlet pressure, and opens to dump the pilot water to drain when outlet pressure (2) becomes less than the inlet water pressure (1), the switch stays open when activated and should be manually reset after activation. The force from the control water pressure together with a spring force holds the control valve spindle seat against the valve seat and seal the control valve causing no water to flow to the power turbine, and from here leak to drain(9) When the device is installed in fire protection systems examples figure 4 and figure 6, the device outlet is connected to the nozzle pipe system intel pipe,
    DK 2017 70097 A1 which in standby is sealed with a normally valve (14) figure 4 or normally closed spray nozzles (5) figure 6, which opens in event of fire in an area the fire protection system protects, in this event pressurized water which has leaked from the device (figure 8) inlet port (1) to the device outlet port (2) drains through the nozzle pipe system, which causes the water pressure on the device's inlet port to exceed the water pressure on the device outlet port (2), and hereby the hydraulic water pressure switch (10) to trip, and connect the control valve (5) pilot chamber (9) via the drain connection pipe (13) to open drain. The drain connection stays open until the hydraulic switch is re-set manually, and the control valve stays open, and in chamber (3) the water supply flow from the water supply is split in two flows, one flow of water flows to the pump device, one flow of water flows through the control valve (5) through the power turbine and to open drain connection (9), and drives the turbine which through it's mechanical shaft connection supply torque force to the pump, which enable the pump to supply it's water flow at enlarged water pressures to the attached nozzle pipe system which is hydraulically connected to the device's outlet port (2).
