hydraulic relief valve

At Water Hydraulic Relief Valve manufacturing process, It described the technological requirements of the pilot valve and main valve.

在纯水液压溢流阀的制造工艺方面，阐述了先导阀与主阀的工艺要求。

The experiments were carried out with different supply pressure, flow rate and the pilot-operated water hydraulic relief valve opening on.

在不同压力、阀口开度等多种条件下，对先导式纯水溢流阀进行了试验研究。

Therefore, It has great practical value that developing excellent performance, long life and high pressure water hydraulic relief valve.

所以，研制出性能优良、使用寿命长以及高压力的水压阀将具有较大的实用价值，这主要从新型工程材料、结构优化设计以及加工工艺等方面入手。
