Pneumatic device, pneumatic control drain valve and water tank
A shell of the pneumatic device is provided with a guide channel extending in the first direction, an air bag is arranged in the guide channel and provided with a movable end, an air inlet piece and the air bag define an air outlet cavity, and a limiting piece is provided with a first limiting part and a second limiting part which are both arranged in the air cavity. The pressure relief piece is movably arranged at the movable end in a penetrating mode, the pressure relief piece is sequentially provided with a limiting section, a sealing section used for being connected with the movable end in a sealing mode and a pressure relief section used for being communicated with the air cavity in the first direction, the limiting section can abut against the first limiting part and the second limiting part, and in the pressure relief state, the pressure relief section is communicated with the air cavity; when the limiting section abuts against the first limiting part, the pneumatic device is in a pressure relief state, when the pneumatic device is in a sealing state, the sealing section is connected with the movable end in a sealing mode, and when the limiting section abuts against the second limiting part, the pneumatic device is in a sealing state. According to the technical scheme, the air bag can automatically relieve pressure after being inflated.
本发明公开一种气动装置、气控排水阀、及水箱，其中气动装置的壳体设有沿第一方向延伸的导向通道，气囊设于导向通道，气囊具有活动端，进气件与气囊限定出气腔，限位件具有均设于气腔内的第一限位部和第二限位部，泄压件活动地穿设于活动端，泄压件在第一方向上依次具有限位段、用以与活动端密封连接的密封段、及用以与气腔连通的泄压段，限位段可分别抵止于第一限位部和第二限位部，在泄压状态，泄压段与气腔连通，当限位段抵止于第一限位部时，气动装置处于泄压状态，在密封状态，密封段与活动端密封连接，当限位段抵止于第二限位部时，气动装置处于密封状态。本发明的技术方案使气囊充气之后能自动进行泄压。
