微阻缓闭止回阀的设计和改造

摘要

This study described the principle and effects of micro slow close check valve, and did some research on the damageable sealing face of valve clack, then came up with a solution to reconstruct the damageable valve clack. Practice has proved that transformation is feasible, and it can bring very significant economic benefits for us.%介绍了微阻缓闭止回阀的结构原理及作用,进而对易损部件,即阀瓣密封面损坏问题进行了研究,提出了对阀瓣修复改造的方法.实践证明,改造方案切实可行,经济效益明显.
