cylinder pressure check

First of all, for strength and stability, mainly a cylinder, cover the wall, the water pressure check and impeller stress test, the axis of strength checking.

首先进行强度和稳定性计算，主要进行了筒体、端盖的壁厚计算、水压试验应力校核以及叶轮、轴的强度校核。

Use a pressure reducing regulator or separate control valve to safely discharge gas from cylinders. Use a check valve to prevent reverse flow into the cylinder.

使用减压调整器或单个的控制阀来安全地从钢瓶中排出气体。采用止回阀，防止回流入钢瓶。

There is a hydraulic lock which is composed of two pilot controlled check valves in the rotary cylinder to retain pressure.

高速回转液压缸内集成了由两个液控单向阀组成的液压锁，对液压缸保压。
