输水管道用自闭阀的设计构思

Design Conception of Self-closing Valve for Water Pipeline

输水管道用自闭阀是针对输水管道普通阀体在停水时打开,再来水时不能自动关闭设计的,该自闭阀是通过密封片在上下水压差和弹簧的弹力作用下产生变形,从而实现自动关闭,结构简单、使用方便。

The self-closing valve was designed for the water pipeline,which could automatically close the valve and stop the water from flowing out of the tap when the final end tap opening without water.The conception of self-closing valve was based on the difference of the hydraulic pressure between the upside and downside pressure of the sealing plate and the elastic force and deformation of the spring.
