The external charging connector 4 is located at the top of valve body 22, for system reserve inflation inlet.
The dustproof and waterproof diaphragm 7 is located at the exit of bleed passage 11, for preventing external contaminants from entering.
Wherein, primary diaphragm 26 is used to separate the connection between the filling channel 9 and inflation/deflation passage 10.When inflation
When, due to being filled with high pressure in filling channel 9, now the lifting surface area of primary diaphragm 26 is larger, will overcome the first spring
24 elastic force, is moved up, and now filling channel 9 is connected with inflation/deflation passage 10, realizes tyre inflating.Secondary diaphragm 29 is used for
Separate the connection between the bleed passage 11 and inflation/deflation passage 10.When deflating, due to being filled with inlet channel 8
Negative pressure, in the presence of negative-pressure sucking, secondary diaphragm 29 will overcome the elastic force of second spring 31, move down, and now deflate
Passage 11 is connected with inflation/deflation passage 10, realizes that tire is quick to atmospheric exhaust.
Specifically, when the present invention carries out the inflation of tire：As shown in Figure 2 and Figure 3, the gases at high pressure of vehicle bridge air flue input port
Valve body is entered by inlet channel 8, flowed to via filling channel 9 at primary diaphragm 26, now, the lifting surface area of primary diaphragm 26 compared with
Greatly, the elastic force of the first spring 24 will be overcome, diaphragm is moved up, and gases at high pressure push check valve 28 open, then gas is via charge and discharge
Gas passage 10 flows to tracheae 5, realizes the inflation of tire, after inflation terminates, the revocation of the normal pressure of inlet channel 8, reverts to normal pressure
Under state, tire pressure backflow, check valve 28 is moved up, and the elastic force of the first spring 24 forces the reset rapidly of primary diaphragm 26, closes
The connection of filling channel 9 and inflation/deflation passage 10, the pressurize after tyre inflating is reached with this；
When the present invention carries out the deflation of tire：As shown in Figure 2 and Figure 3, now, due to being filled with negative pressure in inlet channel 8,
In the presence of negative-pressure sucking, secondary diaphragm 29 will overcome the elastic force of second spring 31, move down, now bleed passage
11 connect with inflation/deflation passage 10, realize that tire is quick to atmospheric exhaust.After deflation terminates, apply at revocation inlet channel 8
Negative pressure, recovers there is no suction in atmospheric pressure state, inlet channel 8, secondary diaphragm 29 is acted on next time in the pressure of second spring 31
To original position, i.e., inflation/deflation passage 10 and bleed passage 11 are separated, the pressurize after bleeding a tire is reached with this.
When needing to perform pressure measurement action after inflation/deflation is finished, wheel side valve assembly is first reached at inflated condition, inlet channel 8
Apply normal pressure, filling channel 9 is connected with inflation/deflation passage 10, the pressure stopped in inflation action, inlet channel 8 is tire
Air pressure, system can measure tire pressure, after the completion of pressure measurement, cancel filling channel a normal pressures, revert under atmospheric pressure state, this moment
The elastic force of first spring 24 forces the reset rapidly of primary diaphragm 26, closes the connection of filling channel 9 and inflation/deflation passage 10, complete
Into tyre pressure-keeping.Wherein, cut-off switch 3 can control the opening and closing between inflation/deflation passage 10 and tracheae 5 according to actual needs.
