    To reduce pressure surges when conveying foodstuffs of the dairy industry, especially milk and yoghurt, a pressure surge compensator (7) is inserted in the feed pipe (2) of a packaging machine and an easily extensible rubber tube (15) is arranged in the tubular casing (14) of the said compensator (7). The rubber tube (15) which is clamped in flanges (16) forms the continuation of the feed pipe (2) and is surrounded by a limiting pipe (20) in order to limit the volume. The said limiting pipe (20) is made of metal and is provided with numerous perforations to permit the passage of air. When a pressure surge occurs, the rubber tube (15) expands (see right half of the figure) and the pressure surge is equalised by a counterpressure prevailing in the annular space (13), which counterpressure may be obtained by means of a compressed air pipe (21), for example. The pressure prevailing in the pipe (21) may be varied by means of a pressure regulator inserted upstream. This device can be cleaned and sterilised in an uncomplicated and simple manner, and it does not take up much space. <IMAGE>

    专利说明:

    The invention relates to a device for regulating fluid flow in a pipe.
    A device for controlling the flow of fluid in a pipe is known, comprising a source of air supply and coaxially arranged chambers, the inside of which has an inlet and outlet for liquid, and the outer one is connected to an air supply source G1].
    The disadvantage of this device for regulating the fluid flow is that it does not fully compensate and absorb the energy of the 12 shock waves in the circuit, i.e. the pressure in the chamber does not reach a level equal to the normal pressure of the fluid flow in the circuit.
    The purpose of the invention is the equalization of fluid pressure during its transportation.
    This goal is achieved by the fact that the device for controlling the fluid flow in the pipe, containing an air supply source and coaxially located chambers, the inner of which has an inlet and outlet for the liquid, and the external connection with the air supply source is provided located between cameras with an additional chamber made of moisture-permeable * material, which serves to limit the expansion of the inner chamber and having a coil-shaped shape with openings for air supply. ,
    In FIG. 1 shows a block diagram of a device; in FIG. 2 - device in two different operating positions.
    The device for regulating the fluid flow in the pipe contains a main pipe 1, which serves to supply liquid to several packaging machines, an additional pipe ^ E, through which liquid from the main pipe flows to each individual packaging machine, a tank 3 with a pump 4, a return pipe 5, coaxially located chambers 6 and 7, the inner of which has an inlet 8 and an outlet 9 for liquid and is a rubber sleeve, and the outer chamber is connected to a source of compressed air 10. Between the chambers 6 and 7 there is an additional chamber 11 made of a moisture-permeable material, such as rubber, which serves to limit the expansion of the inner chamber "

    And having a coil shape with holes 12 for supplying air.
    The operation of the device is as follows.
    A constant flow of liquid is pumped through the main pipe 1 and, when packaging is carried out using various packaging machines, the necessary valve of the pump 4 opens ’for a short time to deliver the required amount of liquid to the bag. The pressure in the additional pipe rises and drops. If one packaging machine is running, only the only packaging bus is connected to the system, the pressure surges that occur when the valve 13 is closed are basically the same all the time. At the point of connection of the inner chamber 7 to the additional pipe 2, directly in front of the valve 13, the pressure surges are compensated and equalized due to the fact that each sudden increase in pressure in the additional pipe 2 leads to a corresponding increase in the volume of the inner chamber 7, which at the same time stretches, overcoming the air pressure inside the additional chamber 11. As a result of choosing the magnitude of this pressure in accordance with the expected pressure jump in the additional pipe 2, the pressure jumps are completely aligned. the tank 14, which is connected through the pipe to the additional chamber 11, the air volume increases so much that it becomes several times larger than the volume of the chamber 7. Moreover, changes in the volume of the additional chamber 11 arising from the movement of the elastic rubber sleeve form part of the total volume of the additional - 40 chamber 11 and tank 14, as a result of which the pressure in the secondary chamber 11 (and tank 14) is kept constant, despite instant changes in the volume of chamber 7. Several packs are connected to the same main pipe paid-machine, and when they are activated or stopped independently of each other, the pressure in the pipe is changed. If the air pressure in the additional chamber 11 is not regulated sufficiently, the tensile strength of the chamber 7 due to pressure surges is sometimes too great, and sometimes too little. ' To equalize the pressure in the additional chamber 11, the pressure is changed using a regulator 15, which regulates the air flow from the source 10 depending on the pressure measured by the sensor 16 installed on the additional pipe 2 before the inlet 8 to the inner chamber 7. The pressure increase, which for example, when another packaging machine is switched on, the pressure regulator 15 increases the pressure in the additional chamber 11 to an appropriate degree so that the tensile resistance corresponds to the pressure in the pipes e 2 before the entrance 8. On the other hand, the pressure sensor 16 does not respond to small and rapid changes in pressure that occur in the additional pipe 2 during operation of the valve 13, since these changes are more or less completely aligned due to the location of the additional chamber 11 between cameras 6 and 7. In order to ensure the correct measurement, the pressure sensor 16 may sometimes be located at a relatively large distance in front of the inlet 8, or be adjusted in such a way that it will only respond to actual pressure changes.
    The proposed device for regulating the flow of liquid in the pipe compared with the known is easier for cleaning and sterilization, it is simple to manufacture and provides more reliable operation.

    And having a coil-like shape with openings 12 for supplying air. The operation of the device is as follows. A steady stream of fluid is pumped through the main pipe 1 and, when packaged with different packaging machines, the required INPUT valve for pump 4 opens 1 for a short time to deliver the required amount of fluid to the bag. The pressure in the additional pipe 2 rises and falls sharply. If one packaging machine is operating, or only a single packaging machine is connected to the system, the pressure surges that occur when the valve 13 is closed are mostly the same amount of time. At the point of connecting the inner chamber 7 to the additional pipe 2, directly in front of the valve 13, the pressure surges are compensated and equalized, because each sudden increase in pressure in the additional pipes 2 leads to a corresponding increase in the volume of the inner chamber 7, which thereby expands the prevailing air pressure is inside the addition chamber 11. As a result of choosing the value of this pressure in accordance with the expected pressure jump in the additional pipe 2, the pressure jumps are completely equalized. With the help The tank 14, which through the pipe is connected to the additional chamber 11, the volume of air increases so much that the OH becomes somewhat larger than the volume of the chamber 7. At the same time, the changes in the volume of the additional chamber -11 occurring when the elastic rubber sleeve moves , make up part of the total volume of the additional chamber 11 and the tank 14, as a result of which the pressure in the additional chamber 11 (and the tank 14) is maintained, despite the instantaneous changes in the volume of the chamber 7. To the same main pipe several packaged x machines, and when they turn on or stop independently of one another, the pressure in the pipe changes. If the air pressure in the additional chamber 11 is not sufficiently controlled, the resistance to stretching of the chamber 7, and due to pressure surges, is sometimes too high and sometimes too low. To equalize the pressure in the additional chamber 11, the pressure is changed by means of the regulator 15, which regulates the air flow from the source 10 depending on the pressure measured by the sensor 16 installed on the additional pipe 2 before the entrance 8 to the internal chamber 7. The increase in pressure A swarm, for example, occurs when another packaging machine is switched on, causes the pressure regulator 15 to increase the pressure in the additional chamber 11 to an appropriate degree so that the tensile strength corresponds to the pressure in No 2 in front of the inlet 8. On the other hand, the pressure sensor 16 does not respond to small and fast pressure changes that occur in the additional pipe 2 when the valve 13 is operating, since these changes are more or less completely equalized due to the location of the additional camera 11 between the chambers 6 and 7. In order to ensure the correct measurement, the pressure sensor 16 may sometimes be located at a relatively large distance in front of the entrance 8, or adjusted in such a way that it will only respond to actual changes in pressure. and The proposed device for regulating the flow of fluid in a pipe, as compared with the known one, is simpler to clean and sterilize, is easy to manufacture, and provides more reliable operation. Claim device for controlling the flow of fluid in the pipe, containing an air supply source and coaxially arranged chambers, internally of which has an inlet and an outlet for the liquid, and an outer one connected to the air supply source, which is equalizing the pressure of the fluid during its transportation, it is equipped with an additional chamber located between the chambers of a moisture-permeable material, which serves to limit the expansion of the inner chamber and has a coil-like shape with openings for supplying air.
