The invention provides an aerostat helium deflation valve and a working method thereof. The helium deflation valve of the aerostat comprises a valve seat used for being installed on an air bag, the valve seat is provided with an A side and a B side which are oppositely arranged, a hole is formed in the valve seat, and a valve cover, a fan and a speed measuring sensor are arranged at the position close to the hole. The fan and the speed measuring sensor used for detecting the rotating flow speed of the fan are rotationally arranged on the A side of the valve seat, and the valve deck capable of moving towards the hole so as to open or close the hole is arranged on the B side of the valve seat. The problems that the air displacement of the helium valve of the aerostat cannot be obtained, and buoyancy loss cannot be accurately controlled are solved, and the hang time and safety of the PLC aerostat can be improved.

    本发明提供一种浮空器氦气放气阀及其工作方法。所述浮空器氦气放气阀包括用于安装在气囊上的阀座,所述阀座具有相对设置的A侧和B侧,所述阀座上设有洞口,靠近所述洞口的位置设有阀盖、风扇和测速传感器,所述阀座的A侧转动设有所述风扇和用于检测风扇转动流速的所述测速传感器,所述阀座的B侧设有能向洞口位移以打开或关闭洞口的所述阀盖。本发明解决了浮空器氦气阀排气量无法获知,不能对浮力损失进行精确控制的难题,有利于提高PLC浮空器的滞空时间和安全性。
