Operation principle of the present utility model is：
Under original state, in gas control port 51 compressed gas are not passed through so that work of first valve element 44 in the first spring 43
The first valve port 13 is blocked with lower, now the compressed gas at air inlet 11 cannot be introduced in the 3rd cavity C；
When gases at high pressure are filled with gas control port 51, these gases at high pressure can flow through successively the first gas control passage 52 and
Second gas control passage 21 and enter first chamber A tip position, force piston 41 that the first valve rod 42 is driven under gas pressure
Move down, the first valve element 44 is moved down and make that the first valve port 13 is turned on, air vent 31 is closed with the first valve rod 42 is synchronous, in air inlet 11
Rapid Jing first chambers A of compressed gas and the first valve port 13 enter in the 3rd cavity C；
Adjust needle 72 not completely block valve outlet port 712 when, in the 3rd cavity C put aside compressed gas have part according to
The valve import 711 of secondary adjusted valve module, valve outlet port 712 and second chamber B flow to gas outlet 12, is that gas is used in the side of gas outlet 12
Equipment is supplied；Under the operating mode that gas outlet 12 has gas to flow out, the compressed gas of the side of gas outlet 12 can react on the second valve rod
62, when the side of gas outlet 12 pressure rise to setting value (for example, it is assumed that admission pressure is 0.6MPa, when the pressure of the side of gas outlet 12
Power reaches 0.3MPa) when, the second valve rod 62 understands shifting in the presence of the lateral pressure of gas outlet 12, promotes the second valve port 14 to be led
Logical, direct the second valve ports of Jing 14 of the compressed gas in the 3rd cavity C flow to gas outlet 12, and now this utility model reaches maximum defeated
Outflow；It should be noted that in this section of course of work, because pressure is higher than the pressure of the side of gas outlet 12 in the 3rd cavity C,
Therefore unidirectional pressure release valve module is closed all the time, i.e., the 3rd valve port 15 will not be switched on；
When stopping filling gases at high pressure to gas control port 51, the air of first chamber A top (i.e. the top of piston 41) position
Rapid Jing the second gas control passages 21, the first gas control passage 52 and gas control port 51 are discharged so that piston 41 is in the first spring 43
Effect is lower to drive the first valve rod 42 to reset, and the first valve element 44 reseals the first valve port 13 so that the gas at air inlet 11 is again
It is secondary to cannot be introduced in the 3rd cavity C, at the same time, on the one hand, because air vent 31 is switched on, the gas of the 3rd cavity C is rapid
Jing air vents 31 are discharged, and the pressure of the side of gas outlet 12 is gradually lowered so that the second valve rod 62 second spring 63 effect under again
Secondary to move down reset, the second valve port 14 is closed, and on the other hand, because the pressure of gas outlet 12 is higher than the pressure of the 3rd cavity C, goes out
The air pressure of the side of QI KOU 12 can promote pressure releasing valve core 81 to move down, and the 3rd valve port 15 is opened, Jing the 3rd successively of the residual voltage at gas outlet 12
Valve port 15, the 3rd cavity C and air vent 31 are expelled to rapidly air.
The above is only better embodiment of the present utility model, therefore all according to described in this utility model patent claim
Construction, the equivalence changes done of feature and principle or modification, be included in this utility model patent claim.
