Abstract
It the utility model is related to a kind of closed loop control of breathing system for operated pneumatic valve control, including source of the gas, the source of the gas order and magnetic valve, first flow speed control valve and rapid escape valve series connection, the inlet end of the rapid escape valve and the pressure chamber of single-action pneumatic executor connect, the outlet side of the rapid escape valve passes through the second flow speed control valve, the non-pressure chamber of check valve and single-action pneumatic executor connects, the inside of the single-action pneumatic executor is separated to form pressure chamber and non-pressure chamber by piston, spring is also set up in the non-pressure intracavitary, one end of the spring is connected with one end of piston towards non-pressure chamber.The utility model control principle is simple, easy to use, using the utility model extraneous corrosive gas and dust gas can be made to cannot be introduced into inside pneumatic actuator, avoid inside pneumatic actuator because corrosive gas or dusty gas enter and caused by premature failure, substantially increase the service life of pneumatic actuator.
Description
Technical field
It the utility model is related to pneumatic control field, especially a kind of closed loop control of breathing system for operated pneumatic valve control
System.
Background technology
Traditional atmospheric control, pneumatic actuator lead in exhaust process, or the non-pressure chamber of single-acting executor
The annexes such as magnetic valve or muffler are crossed to communicate with air.This occupation mode is in the less environment of noncorrosive gases or dust
In, it can filter out a part of dust by muffler etc., but if in the more environment of corrosive gas environment or dust,
Corrosive gas or dust can be entered inside actuator, actuator is produced corrosion and excessive wear, the execution having a strong impact on
The service life of device, while threat is brought to the reliability of control system.
Utility model content
The applicant is directed to above-mentioned existing issue, has carried out Improvement, there is provided a kind of closing for operated pneumatic valve control
Ring around inhales control system, extraneous corrosive gas is cannot be introduced into dust inside actuator using the utility model, effectively carries
The high service life of actuator.
Technical scheme is as follows used by the utility model：
A kind of closed loop control of breathing system for operated pneumatic valve control, including source of the gas, the source of the gas order and magnetic valve,
First flow speed control valve and rapid escape valve series connection, the inlet end of the rapid escape valve and the pressure chamber of single-action pneumatic executor connect
Connect, the outlet side of the rapid escape valve is connected by the non-pressure chamber of the second flow speed control valve, check valve and single-action pneumatic executor
Connect, the inside of the single-action pneumatic executor is separated to form pressure chamber and non-pressure chamber by piston, in the non-pressure intracavitary
Spring is also set up, one end of the spring is connected with one end of piston towards non-pressure chamber.
The beneficial effects of the utility model are as follows：
The utility model control principle is simple, easy to use, using the utility model can make extraneous corrosive gas and
Dust gas cannot be introduced into inside pneumatic actuator, avoid inside pneumatic actuator because corrosive gas or dusty gas enter
And premature failure is caused, substantially increase the service life of pneumatic actuator.

Embodiment
Illustrate specific embodiment of the present utility model below.
As shown in figure 1, a kind of closed loop control of breathing system for operated pneumatic valve control includes source of the gas 7, the order of source of the gas 7 with
Magnetic valve 1, the first flow speed control valve 5 and rapid escape valve 2 are connected, the inlet end 201 and single-action pneumatic executor of rapid escape valve 2
4 pressure chamber 401 is connected, and the outlet side 202 of rapid escape valve 2 is pneumatically held by the second flow speed control valve 6, check valve 3 with single-acting
The non-pressure chamber 402 of row device 4 connects, and the inside of single-action pneumatic executor 4 is separated to form pressure chamber 401 and non-by piston 404
Pressure chamber 402, also sets up spring 403 in non-pressure chamber 402, and one end of spring 403 and piston 404 are towards non-pressure chamber 402
One end connection.
Specific work process of the present utility model is as follows：
As shown in figure 1, magnetic valve 1 must be electric, source of the gas 7 enters single by magnetic valve 1, the first flow speed control valve 5, rapid escape valve 2
The pressure chamber 401 of action pneumatic executor 4, promote non-pressure of the piston 404 to left movement, now single-action pneumatic executor 4
Air in chamber 402 is discharged through overcompression from check valve 3.When the dead electricity of magnetic valve 1, spring 403 promotes piston 404 to move right,
Gas in the pressure chamber 401 of single-action pneumatic executor 4 enters single-acting gas by rapid escape valve 2, the second flow speed control valve 6
The non-pressure chamber 402 of dynamic actuator 4.It is pneumatic to be advantageous to regulation single-acting for the first flow speed control valve 5 and the second flow speed control valve 6 in this process
The air inlet of actuator 4 and the speed of service of outlet.
The utility model control principle is simple, easy to use, using the utility model can make extraneous corrosive gas and
Dust gas cannot be introduced into inside pneumatic actuator, avoid inside pneumatic actuator because corrosive gas or dusty gas enter
And premature failure is caused, substantially increase the service life of pneumatic actuator.
Above description is to explanation of the present utility model, is not the restriction to utility model, what the utility model was limited
Scope is referring to claim, and in the case of without prejudice to general principle of the present utility model, the utility model can make any shape
The modification of formula.
