1·The bulk container can fix the extension tube well while not affecting the normal work of the liquid tapping valve.

本发明既能良好的固定延伸管，同时也不妨碍放液阀的正常工作。

2·Removing the extension tube shortens the spacing to allow any binocular viewer to reach focus without a Barlow lens.

除去延长管缩短 间隔让任何的用两眼的观众到达没有一个巴罗镜的焦点。

3·The balance extension tube functions to retain balanced pressure in front and at the back of the cleaner prior to the opening of the valve to prevent it from impacting the valve core.

发球筒平衡接管的作用是在通球初始时，出球接口端的阀门未开启前使清管器在发球筒中处于前后压力平衡，不能撞向阀芯。

4·Shock absorber sliding tube is correct extension and cleanliness.

减震支柱内筒伸出正常且洁净。

5·The Extension consists of a length of steel tube with a coupling on one end to attach to the valve, and a coupling on the other end to attach to a handwheel or some other type of operating device.

阀杆加长件由带连接在阀门上的联轴节的钢管长度，连接在手轮上的联轴节，或其它类型的操作机构组成。

6·The simulation results show that, the extension of priority valve cracking time, shortening tube length and increasing tube diameter will be helpful to reduce the hydraulic impact.

仿真结果表明，通过增大优先阀开启时间，适当缩短管路长度和增大管径能够有效降低液压系统的液压冲击现象。
