Safety type corrugated pipe gate valve

According to the safety type corrugated pipe gate valve, the pressure gauge is additionally arranged at the bottom of the packing of the valve deck, once a corrugated pipe is broken, pressure cannot be leaked immediately, due to the fact that the packing is sealed, the packing can fail along with long-time use, the pressure gauge can give out numerical reminding, the corrugated pipe is prone to breaking, and the safety of the valve is guaranteed. 一种保险型波纹管闸阀，通过在阀盖的填料底部加装一个压力表，一旦波纹管破裂，压力不会马上泄露，因为还有填料密封，随着时间长了填料也会失效，但压力表就会有数值提醒，这样就很容易波纹管破裂的问题，从而保证了阀门的安全。
