The invention relates to the technical field of ventilation, and discloses a pneumatic mushroom-shaped ventilator which comprises a ventilator body, a hood, a reversing valve, a driving air cylinder, a hand wheel, a weather-tight cover, a transmission rod and a position sensor, the weather-tight cover is installed in the hood in an up-and-down opening and closing state through the transmission rod connected with the weather-tight cover, and opening and closing actions are completed through up-and-down movement of the driving air cylinder or the hand wheel. The reversing valve is a manual/automatic switching reversing valve, the driving air cylinder is connected with the reversing valve through a hose, a position sensor corresponding to the wind and rain sealing cover is arranged in the wind cap, and the driving air cylinder and the wind cap are fixed through bolts. Remote automatic opening and closing of the ventilator are achieved through the reversing valve and the driving air cylinder, manual opening and closing of the ventilator are achieved through hand wheel operation under the power-off and gas-off conditions, electric control pneumatic operation and multifunctional manual operation are integrated, opening and closing of the ventilator under the power-on, ventilation, power-off and gas-off conditions can be met, the structure is simple, operation is convenient, and applicability is high.
本发明涉及通风技术领域,公开了一种气动菌形通风筒,包括筒体、风帽、换向阀、驱动气缸、手轮、风雨密盖、传动杆和位置传感器,风雨密盖经与之连接的传动杆呈上下启闭状态安装于风帽内,通过驱动气缸或者手轮的上下运动来完成启闭动作,所述换向阀为手/自切换换向阀,所述驱动气缸与换向阀之间设有软管连接,所述风帽内设有对应风雨密盖的位置传感器,所述驱动气缸与风帽设有螺栓固定。本发明通过换向阀、驱动气缸实现通风筒的远程自动启闭,以及在断电、断气情况下通过手轮操作实现通风筒的手动启闭,集电控气动、多功能手动为一体,能满足通电通气、断电断气状况下通风筒的启闭,结构简单、操作方便,适用性强。
