The safety and reliability of envelope.
Utility model content
The technical problems to be solved in the utility model is that overcome the deficiencies of the prior art and provide a kind of structure simple, reliable,
The intake and exhaust component that can prevent gas-flow closure circle from leaking when dying.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of gas-flow closure circle anti-leak intake and exhaust component, including intake and exhaust pipeline, the air inlet-outlet pipe road is equipped with can
Check valve is controlled, the controllable check valve is equipped with the normally closed solenoid valve for switching direction.
As a further improvement of the above technical scheme: the air inlet-outlet pipe road is equipped with double electricity for intake and exhaust switching
Solenoid valve is controlled, the controllable check valve is between double electric control solenoid valves and gas-flow closure circle.
As a further improvement of the above technical scheme: the normally closed solenoid valve is 2/2-way normally closed solenoid valve, institute
Stating double electric control solenoid valves is the double electric control solenoid valves of two-bit triplet.
As a further improvement of the above technical scheme: the air inlet-outlet pipe road is additionally provided with for detecting gas-flow closure circle
The pressure switch of interior pressure, the pressure switch are equipped with alarm, and pressure switch is located at gas-flow closure circle and the controllable list
To between valve.
As a further improvement of the above technical scheme: gas-flow closure circle is installed in obturator.
Compared with the prior art, the advantages of the utility model are: gas-flow closure circle anti-leak disclosed by the utility model
Intake and exhaust component, air inlet-outlet pipe road setting controllable check valve, controllable check valve realize cutting for direction by normally closed solenoid valve
It changes, when normally closed solenoid valve power loss, intake and exhaust pipeline can be inflated in gas-flow closure circle by controllable check valve, normally closed type electromagnetism
When valve obtains electric, controllable check valve reverse-conducting, gas could be discharged by intake and exhaust pipeline in gas-flow closure circle, and normally closed type is electric
The movement of magnet valve is not died and is influenced, therefore when occurring powering off gas-break phenomenon namely when normally closed solenoid valve power loss, controllably
Check valve can not reverse-conducting, gas can not be discharged by intake and exhaust pipeline in gas-flow closure circle, so as to effectively prevent breaking
Gas leaks in gas-flow closure circle in the case of electricity is died.
Detailed description of the invention

Each label indicates in figure: 1, intake and exhaust pipeline；2, controllable check valve；3, normally closed solenoid valve；4, double electric control electromagnetics
Valve；5, gas-flow closure circle；6, pressure switch.
Specific embodiment
The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.
Fig. 1 shows a kind of embodiment of the utility model gas-flow closure circle anti-leak intake and exhaust component, the present embodiment
Gas-flow closure circle anti-leak intake and exhaust component, including intake and exhaust pipeline 1, intake and exhaust pipeline 1 are equipped with controllable check valve 2, controllably
Check valve 2 is equipped with the normally closed solenoid valve 3 for switching direction.
Controllable check valve 2, controllable check valve 2 are arranged in intake and exhaust pipeline 1 for the gas-flow closure circle anti-leak intake and exhaust component
The switching that direction is realized by normally closed solenoid valve 3, when 3 power loss of normally closed solenoid valve, 2 forward conduction (attached drawing of controllable check valve
In for from bottom to top be connected), intake and exhaust pipeline 1 can be inflated in gas-flow closure circle 5 by controllable check valve 2, normally closed type electromagnetism
When valve 3 obtains electric, 2 reverse-conducting of controllable check valve (is connected) from top to down in attached drawing, and gas could pass through in gas-flow closure circle 5
Intake and exhaust pipeline 1 is discharged, and the movement of normally closed solenoid valve 3 is not died and influenced, therefore when occurring powering off gas-break phenomenon,
Namely 3 power loss of normally closed solenoid valve, controllable check valve 2 can not reverse-conducting, gas can not pass through intake and exhaust in gas-flow closure circle 5
Pipeline 1 is discharged, so as to effectively prevent in the case of dying gas in gas-flow closure circle 5 to leak.
Further, in this embodiment intake and exhaust pipeline 1 is equipped with double electric control solenoid valves 4 for intake and exhaust switching, it can
Check valve 2 is controlled to be located between double electric control solenoid valves 4 and gas-flow closure circle 5.If double electric control solenoid valves 4 are logical to inflation actuation coil
Electricity then inflates movement gas circuit and connects (total air inlet in left side in attached drawing), even if inflation acts gas after to inflation actuation coil power-off
What road was still to turn on, it will be maintained to until being powered to exhaust event coil；If being powered to exhaust coil, exhaust is dynamic
Make gas circuit and connects (exhaust on right side in attached drawing), even if be still to turn on to exhaust coil blackout final vacuum gas circuit, it will one
It is straight to maintain until being powered to inflation actuation coil, namely realization " self-locking ", it is not influenced by powering off, while double electric control solenoid valves
4 movement is not also died and is influenced, and advantageously ensures that intake and exhaust component is not influenced by dying, and keeps normal work shape
State.
As a preferred technical solution, in the present embodiment, normally closed solenoid valve 3 is 2/2-way normally closed solenoid valve, double electricity
Controlling solenoid valve 4 is the double electric control solenoid valves of two-bit triplet.
Further, in this embodiment being additionally provided with the pressure for detecting pressure in gas-flow closure circle 5 in intake and exhaust pipeline 1
Power switch 6, pressure switch 6 are equipped with alarm (not shown), and pressure switch 6 is located at gas-flow closure circle 5 and controllable unidirectional
Between valve 2.When pressure switch 6 detects that pressure is lower than the minimal pressure force value set in gas-flow closure circle 5, alarm equipment alarm,
And intake and exhaust pipeline 1 is inflated in gas-flow closure circle 5, until pressure switch 6 detects that the pressure in gas-flow closure circle 5 reaches and sets
When fixed normal value, stop inflation.
Further, in this embodiment gas-flow closure circle 5 is installed in obturator.Obturator for example can be jelly
The equipment demanding for sealing performance such as dry machine, isolator, pressure vessel, advantageously ensures that sealing using gas-flow closure circle 5
Performance.
Although the utility model has been disclosed with preferred embodiment as above, it is not intended to limit the utility model.It is any
