针对当前生产生活中减压阀存在的泄漏现象,通过对减压阀结构特征和工况下阀体内压力差的分析,揭示了减压阀在不同工况下产生持续泄漏或过大泄漏的原因;提出了高密封性的最大面积接触式的阀体内部密封的设计方法,设计出了凹型密封垫片和弹性活塞密封结构。该文主要针对典型的自来水减压阀进行了优化设计,通过计算或测量流量的方法,对优化设计后的自来水减压阀泄漏量进行监测,得出优化设计后的自来水减压阀的持续泄漏或过大泄漏问题得到有效解决。优化设计后的减压阀在很大程度上减少了泄漏,增强了密封、稳压能力,并降低了故障率,提高了使用寿命。该减压阀的优化设计对减压阀的应用以及技术的发展具有重要意义。

Aiming at the leakage phenomenon of the pressure reducing valve in the current production life, through the analysis of the structural characteristics of the pressure reducing valve and the pressure difference in the valve body under the working condition, it is revealed that the pressure relief valve produces continuous leakage or over . And the design method of the internal seal of the valve body with the largest area of contact is put forward, and the concave sealing gasket and the elastic piston sealing structure are designed. In this paper, the typical design of the tap water valve is optimized, and the method of calculation or measure the flow is used to monitor the leakage of the pressure reducing valve. It is concluded that after the optimization design of tap water pressure reducing valve of continuous leakage or excessive leakage phenomenon is effectively improved. And it is largely reduced the leaks, enhance the capacity of sealing, voltage regulator, and reduce the failure rate, improve the service life. The optimization design of the pressure reducing valve is of great significance to the development of the technology and the application of the pressure reducing valve.
