101, while promoting the second movable axis 411 by second spring 410, second boss 420 is closed second flow channel three section 123, LP
Gas flows into first flow 110；When flowing through left terminal 2, because LP gas pressures are more than 11 cun, left side spring is overcome completely
203 elastic force, promotes the first 212 apical grafting left side Non-return ring 207 of pressure sensitivity, and closure two sections of 112, LP gases of first flow can not be by outlet
Mouth 103 flows out.
When LP gases access the second air inlet 102, gas pressure is more than 11 cun, overcomes the elastic force of right side spring 303, pushes away
The deformation to the right of dynamic right atrial pressure plate 305, opens two sections of 122, LP gases of second flow channel and is flowed out by gas outlet 103.
Above-described embodiment is preferred scheme of the present utility model, and the utility model can also have other embodiments.Ability
The technical staff in domain can also make equivalent variations or replacement on the premise of without prejudice to the utility model spirit, these equivalent changes
Type or replacement are all contained in the scope set by the application claim.
