液控单向阀保压失效问题的研究

The Research on Keeping Pressure Expiration in Hydraulic Control Non-return Valve

阐述了液控单向阀保压原理,对液控单向阀保压失效原因进行了分析,并提出三种可行的解决方案.经实践证明,此三种方案均可有效地解决液控单向阀保压失效问题.

This paper aims at the problem of keeping pressure expiration in hydraulic control non- return valve in engineering and introduces their operation principle in detail. It also analyzes the causation of the keeping pressure expiration and present three feasible projects. According to the practice, the problem of the keeping pressure expiration can be solved by using three projects.
