Pneumatic device for needle valve pressure relief, pneumatic control drain valve and water tank
The invention discloses a pneumatic device for needle valve pressure relief, a pneumatic control drain valve and a water tank, the pneumatic device for needle valve pressure relief comprises an air inlet cover, an inflation telescopic part, a driven part and a self-pressure-relief part, the air inlet cover is in sealed communication with the inflation telescopic part, the air inlet cover can inflate the inflation telescopic part, and the driven part is in sealed communication with the self-pressure-relief part. The driven part is connected to the movable end of the inflatable telescopic part, the driven part can reach the bottom of the shell, the pneumatic device for needle valve pressure relief further comprises an opening and closing mechanism, and the opening and closing mechanism can enable the air leakage groove to be communicated with an inner cavity of the inflatable telescopic part and enable the inflatable telescopic part to be subjected to air leakage and contraction. The pneumatic control drain valve comprises the pneumatic device for pressure relief of the needle valve. The water tank comprises the pneumatic device for needle valve pressure relief. By the adoption of the pressure relief device, pressure relief can be automatically conducted after inflation is completed, operation is reliable, the structure is very simple, electrical parts can be saved, and cost is low.
本发明公开了一种针阀泄压的气动装置、一种气控排水阀及一种水箱，所述针阀泄压的气动装置包括进气盖、充气伸缩件、从动件和自泄压件，所述进气盖与所述充气伸缩件密封连通，所述进气盖能够往所述充气伸缩件内充气，所述从动件连接于所述充气伸缩件的活动端，所述从动件能够到达所述壳体底部，所述针阀泄压的气动装置还包括开闭机构，所述开闭机构能够使所述泄气槽与所述充气伸缩件的内腔连通并使所述充气伸缩件泄气收缩。所述气控排水阀包括如上所述的针阀泄压的气动装置。所述水箱包括如上所述的针阀泄压的气动装置。采用本发明，能够在充气完毕后自动进行泄压，运作可靠而且结构非常精简，能够节省电气件，成本较低。
