| Abstract: | The improved design of adopting plug-in valve in hydraulic system of ZD4800/18.5/2.9 type hydraulic powered support are presented. The principle of working and function of machine are analyzed. The conclusion deem: the hydraulic systems of powered support of adopting plug-in valve have powerful capacity of resisting pollution. the long life of valve: high reliability of working,low leakage and pressure loss,high efficiency and simplified system, easy to design and manufacture, maintenance and apply, powerful capacity of flow. It can adapt the requirement of high-speed moving powered support, satisfy the requirement of some special working condition and other outstanding advantage. It is worth to popularize. |
