Another kind of preferred scheme, just be located in the valve body the valve pocket below is equipped with the compression chamber, the valve pocket with the compression chamber is separated by the intermediate lamella in the valve body, the upper portion of valve floodgate is located in the valve pocket, and the middle part is worn to locate on the intermediate lamella, the lower part is located in the compression chamber, the lower part will the compression chamber divide into cavity and cavity down, the valve body be equipped with go up the air flue of cavity intercommunication and with the air flue down of cavity intercommunication.

In another preferred scheme, the outlet hole is circularly formed in the upper end face of the valve body, the inlet hole is formed in the side face of the valve body, the upper end portion of the valve gate is in a frustum shape, and when the quick-release valve is closed, at least part of the upper end portion of the valve gate is sealed and arranged on the port of the inner side of the inlet hole.

In another preferred scheme, a silencer is arranged on the valve body.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages: the utility model discloses utilize direct joint and T type to connect the quick installation that realizes the fast valve of arranging to interior sealing washer and the outer sealing washer that cup joints have greatly improved sealed effect, have guaranteed pneumatic control's normal operating.
