Description

The utility model relates to pipeline valves, namely, gas pressure control devices, and can be used in various industries and agriculture.
A known pressure regulator comprising a housing with inlet and outlet nozzles, a sensing element mounted in the housing with a spring-loaded rigid center and a regulating body made in the form of a nozzle and a damper in the form of a flaccid membrane contacted through a spring-loaded stop with one end of the rod located in the central hole nozzle, the other end of which is connected with a spring-loaded rigid center, radial and annular grooves made in the housing around the nozzle, the tops of the protrusions of which are located in one plane ty, while the sluggish membrane is freely placed between the nozzle and the spring-loaded stop with a gap along its outer diameter, designed to connect the inlet pipe with the specified grooves of the housing [1].
The regulator can be used in instruments and gas analysis systems, however, its design does not allow to obtain high, for example, up to 100 atmospheres, outlet pressure, due to the lack of the necessary technical means in the regulator, since a simple increase in the force of the task spring entails It means an increase in the size and weight of the regulator, as well as a multiple increase in the force on the adjusting screw of the sensing element during its adjustment.
A gas reducer is known, comprising a housing with a seat and a cover, a tuning part mounted in the housing, consisting of a tuning screw with a spring, a membrane and a pusher, and a pressure reducing valve including a hollow housing in which the seal is installed
and a piston with a spring. Increasing the constancy of the outlet pressure of the gas stream, and hence the unevenness coefficient, and reducing the dimensions and weight of the gearbox are achieved by the fact that in the seal of the reducing valve a balancing chamber is made, limited by the piston and having a diameter equal to the diameter of the seat [2]. In terms of the essential features, the gearbox is closest to the claimed utility model and adopted as a prototype.
The reducer has a fairly high technical and operational characteristics, however, in it, as in the device according to [1], there is no possibility of obtaining a high output pressure, due to the lack of technical equipment necessary for this.
The objective of the utility model is to create a small-sized gas reducer, the pressure increase at the outlet of which would be carried out without increasing the force on its tuning screw.
The problem is solved in that in a gas reducer comprising a housing with a seat and a cover, a tuning part mounted in the housing, consisting of a tuning screw with a spring, a membrane and a pusher, and a reducing valve, including a hollow housing with a through channel, a seal and a spring, a balancing chamber , communicated with the cavity of the working pressure of the housing using the specified through channel, according to a utility model, the tuning part is equipped with a hydraulic booster mounted in the supmembrane cavity with support on the membrane and a piston a unit installed under the spring of the adjusting screw with the possibility of contact of the piston with the hydraulic booster.
It is advisable to use soft rubber as the working medium of the hydraulic booster.
It is advisable to carry out the balancing chamber in the housing, and install the pressure reducing valve in the chamber with an annular gap relative to its wall, and provide the camera with a control
valve, the spring of which to use the spring of the reducing valve.
It is advisable to perform the balancing chamber in a stub rigidly and hermetically connected to the housing.
It is advisable to perform the reducing valve with an annular element made of elastic material placed in the reciprocal groove on the outer surface of the hollow body.
It is advisable that the annular element of the reducing valve is made of fluoroplastic.
It is advisable to seal the reducing valve with a spherical shape with a two-stage through channel, in the steps of a larger diameter which mark the end of the pusher of the membrane, and in the steps of a smaller diameter - the end of the control valve.
When using the utility model, a technical result can be obtained, which is expressed in the possibility of obtaining at the output of a small-sized gas gearbox a high working pressure without increasing the force on its tapping screw with a simultaneous increased gas flow through the gearbox, which is caused by the installation of a power steering unit in the gearbox gearbox, the piston of which connected to the tapping screw through the spring of the latter, and the implementation of the balancing chamber in the gear housing (or in a hermetically and rigidly connected to pusom plug), and placing the reducing valve in this chamber with an annular gap relative to the wall of the latter and the control valve to cooperate with a pusher of the membrane and the reducing valve under spring action of a reducing valve.
Other advantages of the claimed utility model will be visible from the description and drawing, which shows a general view of the gas reducer, a longitudinal section.
The gas reducer comprises a housing 1 with a seat 2 and a cover 3, a tuning part mounted in the housing, including a tuning screw 4, a spring 5, a membrane 6 with a support plate 7, to which the pusher 8 is rigidly connected, a hydraulic booster 9 made of soft rubber and installed in a supranembrane cavity with a support on the membrane 6, and a piston assembly 10 mounted under the spring 5 with the possibility of piston contacting with the hydraulic booster, a pressure reducing valve including a hollow body 11 with a sphere-shaped seal 12 equipped with a two-stage flow channel ohm 13, in the step of a larger diameter which has the end of the pusher 8, and an annular element 14 of elastic material, such as fluoroplastic, placed in the reciprocal groove 15 on the outer surface of the hollow body 11, which is installed in the balancing chamber 16 with an annular gap relative to the wall of the latter, designed for pneumatic communication of the chamber with the high-pressure cavity 17 of the housing 1. The chamber 16 can be made in a stub 18 which is rigidly and tightly connected with the housing 1, as shown in the drawing, and is equipped with a control a valve 19, one end of which is installed in the step of the smaller diameter of the flow channel 13 opposite the pusher 8, and the other end is installed in the landing hole 20 of the plug, while both valves are spring-loaded in the direction of the seat 2 and pusher 8 in the initial state shown in the drawing, the screw 4 is turned out, the spring 5 is not loaded, the spring 21 presses the pressure reducing valve with the seal 12 to the seat 2, and the control valve 19 - to close the flow channel 13 in the seal 12. When gas is supplied through the inlet Tucer 22, he will enter the cavity 17 of the high pressure and the associated balancing chamber 16 to align with the pressure in the cylinder. The passage of gas into the cavity 23 of the working pressure is excluded.
Gas gear works as follows. In the mode of gas flow under pressure at the outlet of the gearbox at 100 atmospheres, the spring 5 is loaded by rotation of the adjusting screw 4, which, through the piston assembly 10, the hydraulic booster 9 and the membrane 6, moves the pusher 8 together with the control valve 19 to the lower (according to the drawing) position with a gap between seal 12 and valve 19. In this case, if there was no hydraulic booster in the gearbox, an outlet pressure of 100 atmospheres and a membrane area of 7 cm 2, the force applied to the adjusting screw 4 would be about 700 kgf. The presence of a hydraulic booster in the tincture of the gearbox at the same pressure at its outlet reduces the value of the indicated force by almost an order of magnitude, and it will lie in the range of 60-70 kgf. At the same time, the balancing chamber 16 through the flow channel 13 communicates with the working pressure cavity 23, and the gas from the chamber 16 enters the cavity 23, and the gas pressure in the chamber 16 begins to decrease, as a result of which the force acting on the pressure reducing valve from the gas pressure from the side of the cavity 17, will exceed the force acting on the reducing valve from the side of the chamber 16, and the latter will begin to move towards the control valve 19. At the same time, a gap is formed between the seat 2 and the seal 12 of the reducing valve, through which additional the resulting outflow of gas from the high-pressure cavity 17 into the working pressure cavity 23, which is connected by a channel 24 to the submembrane cavity 25. The gas pressure in the cavity 23 and the associated cavity 25 rises until the force acting on the membrane 6 from the gas pressure will not balance with the force acting on it from the side of the hydraulic booster 9 and spring 5. As a result, the membrane 6, the pusher 8 and the valve 19 will occupy a position in which an increased gas flow at constant pressure is ensured. The pressure reducing valve occupies a position in which the outflow of gas from the balancing chamber 16 into the working pressure cavity 23 through the channel 13 is aligned with the gas flow from
cavities 17 of high pressure into the balancing chamber 16 through the gap between the annular element 14 and the wall of the chamber. When gas sampling ceases, the pressure in the cavities 23 and 25 begins to increase, while the spring 5 is compressed through the hydraulic booster 9 and the piston assembly 10, and the membrane 6, the pusher 8, the valve 19 under the action of the spring 21 are moved towards the closing of the valve 19, which in turn pushes the pressure reducing valve to the seat 2, gas flow is stopped. As a result, the pressure in the cavity 17 and the balancing chamber 16 is equalized, which leads to an additional preload of the pressure reducing valve to the seat 2 due to the pressure difference between the balancing chamber 16 and the working pressure cavity 23.
The prototype gearbox successfully passed the tests in the oxygen supply system from the cylinder during welding.
In a simplified mode of operation, when an increased gas flow through the gearbox is not required, its advanced tuning part can be mounted to obtain high working pressure on guest and any other gearboxes, due to its high reliability, simplicity of design and control, as well as preventive maintenance and repair
