The invention provides an integrated pneumatic combination valve, a pump valve device and a controller device.The pneumatic combination valve is characterized in that a valve body shell is provided with an air guide channel, the air guide channel comprises an air guide cavity, at least one air inlet and an air outlet communicated with the air guide cavity, a switch assembly comprises a valve element and a variable elastic sealing body, the valve element is arranged in the air guide cavity, and the valve element is arranged in the air guide cavity; the variable elastic sealing body is arranged at at least one end of the valve element and comprises an annular elastic deformation part. The switch assembly has a first state and a second state, in the first state, the valve element is located at the initial position, and the elastic deformation part deforms in the direction away from the air inlet under gas pressure so that the air inlet can be communicated with the air guide cavity, and in the second state, the valve element is located at the initial position, and the elastic deformation part deforms in the direction close to the air inlet under gas pressure. And the air inlet is blocked from the air guide cavity. The pneumatic combination valve provided by the invention is simple in structure, and not only can realize a switch controllable function, but also can realize a one-way conduction function.
本申请提供一种一体式气动组合阀、泵阀装置及控制器装置,其中气动组合阀包括:阀体外壳设有导气通路,导气通路包括导气腔和至少一个进气口、以及与导气腔连通的出气口,开关组件包括阀芯和可变弹性密封体,阀芯设于导气腔内,可变弹性密封体设于阀芯的至少一端,可变弹性密封体包括环状的弹性形变部;开关组件具有第一状态和第二状态,第一状态时,阀芯位于初始位,弹性形变部受气体压力向远离进气口方向形变,使得进气口与导气腔连通,第二状态时,阀芯位于初始位,弹性形变部受气体压力向靠近进气口方向形变,使得进气口与导气腔阻断。本申请提供的气动组合阀结构简单,既能实现开关可控功能又能实现单向导通的功能。
