Abstract

The proposed utility model relates to stop valves for controlling the flow of medium in pipelines and can be used in various pneumatic and hydraulic systems (hereinafter - ASG), including with aggressive and toxic environments, in various fields of technology. The utility model solves the technical problem of ensuring valve tightness for a long time under the influence of pressure of the working medium, when operating in the "pulse" mode after the initial operation, as well as the possibility of repeated use of the valve, for example, when testing ASG at the bench. To solve this technical problem, in a valve containing a housing with inlet and outlet channels, a locking member pressed against the valve seat by a spring, a locking member drive and a control pressure supply channel, the input channel is made in the form of a sealed cup with a destructible bottom, the locking member is located in relation to the seat on the side of the inlet channel, equipped with a seal on the valve seat and a pusher to destroy the bottom, in the valve body there is a catcher of destructible bottom, and the drive of the shut-off element is made in the form of pores nya. For the purpose of multiple use of the valve, for example, during bench testing of ASG, a sealed cup with a destructible bottom is made removable and installed in the inlet of the valve, for example, on a thread using a sealing gasket.

Description

The proposed utility model relates to stop valves for controlling the flow of medium in pipelines and can be used in various pneumatic and hydraulic systems (hereinafter - ASG), including with aggressive and toxic environments, in various fields of technology.

The closest technical solution, selected as a prototype, is a valve according to copyright certificate No. 5449633 - F 16 K 1/00, F 16 K 31/126. The valve comprises a housing with inlet and outlet channels, a flexible inelastic cup (locking actuator), to the end of which a locking organ is attached, pressed against the valve seat by a spring, and a channel for supplying a control medium. Common features with the proposed utility model are a housing with input and output channels, a locking member pressed against the valve seat by a spring, a locking member drive and a channel for supplying a control medium.

The disadvantage of this valve is the inability to use it in ASG, which must be kept closed for a long time under the influence of a high-pressure medium, especially under the influence of aggressive and toxic media, due to the fact that when the valve is in the closed position, the shut-off element is pressed against the valve seat only by spring force , and the pressure of the working medium creates a force on the locking element, the opposite force of the spring. As a result, during prolonged exposure to ASG under the pressure of the working medium, leakage at the junction of the locking element and valve seat is inevitable.

The proposed utility model solves the technical problem of ensuring valve tightness for a long time under the influence of the pressure of the working medium, when working in "pulse" mode

after the initial actuation, as well as the possibility of repeated use of the valve, for example, when testing ASG at the stand.

To solve this technical problem, in a valve containing a housing with inlet and outlet channels, a locking member pressed against the valve seat by a spring, a locking member drive and a control pressure supply channel, the input channel is made in the form of a sealed cup with a destructible bottom, the locking member is located in relation to the seat on the side of the inlet channel, equipped with a seal on the valve seat and a pusher to destroy the bottom, in the valve body there is a catcher of destructible bottom, and the drive of the shut-off element is made in the form of pores nya.

In order to reuse the valve, for example, during bench testing of ASG, the sealed cup with a destructible bottom is made removable and installed in the valve inlet channel, for example, on a thread using a sealing gasket.

Distinctive features of the proposed valve are the following: the inlet channel is made in the form of a sealed cup with a destructible bottom, the locking element is located relative to the seat on the side of the inlet channel and is equipped with a seal on the valve seat, and a pusher to destroy the bottom, the valve body has a destructible bottom catcher, and the drive of the locking member is made in the form of a piston, and also, in addition, the sealed cup with destructible bottom is removable.

Due to the presence of these distinctive features, in combination with the known ones, the following result is achieved: the valve is sealed for a long time under the influence of the working medium pressure, especially aggressive or toxic. The valve also provides tightness during its operation in closing mode after destruction of the bottom of the sealed glass. And due to the removability of the sealed glass, the possibility of using this

valves as reusable in, for example, laboratory or bench tests.

As a result of a search by sources of patent and scientific and technical information, no solutions containing similar features were found. Thus, we can conclude that the proposed technical solution is not known from the prior art and, therefore, meets the eligibility criterion of “new”.

The proposed technical solution can be used as a shut-off element in high-pressure ASGs, as well as in systems with aggressive and toxic media, followed by its use in a "pulse" mode with repeated use, which allows us to conclude that the criterion of "industrial applicability" is met.

The utility model is illustrated in the figure.

The valve shown in the figure contains a housing 1 with input 2 and output 3 channels, a locking element 4 with a seal 5, a piston 6, a valve seat 7, a spring 8, a control pressure supply channel 9 and an airtight cup 10 with a bottom 11, an abutment 12, and a spring clip 13. In this case, the sealed cup 10 with destructible bottom 11 is made removable, mounted in the housing on the thread through the seal (not shown in the figure).

The device operates as follows.

In the initial operating position, the locking member 4 with the seal 5 is pressed against the seat 7 by the spring 8, while the valve tightness for a long time under the influence of the pressure of the working medium is ensured by a tight cup 10. When the control pressure is applied to the channel 9, the piston 6 with the locking member 4 moves up, in this case, the bottom 11 of the sealed cup 10 is cut and the passage for the working medium located in the inlet channel 2 opens. The bottom 11 is cut off without a water hammer, since there is no effect on the liquid. For a clean cut for the glass, an emphasis is set

12. To fix the bottom 11 after the cut, a spring clip 13 is provided. When the control pressure is released, the locking element 4, under the influence of the spring 8 and the pressure of the working medium, is lowered onto the saddle 7, ensuring the tightness of the ASG. Subsequent supply and discharge of control pressure provides a "pulse" mode of operation of the valve. After using the valve, the sealed cup 10 and the bottom 11 are alternately removed from the housing 1, and a new sealed cup 10 with the bottom 11 is installed in their place.
