阀体

The bottom of the disc is made of knife-shaped gate with a cut off function of the medium. When gate is closed , oblique plane of gate valve encounters wedge block of gate to achieve sealing effect.

闸板底部做成刀形斜面具有切断介质功能，而且闸板关闭时通过阀体上的锲块紧靠闸板斜切面使得闸板紧紧贴靠阀座密封面，从而起到了密封效果。

With the complication and diversification of components, Composite Hydraulic Manifold Block which installed plate valves, lap valves and cartridge valves is the mainstream in the application and development of integrated hydraulic system.

随着液压元件日益复杂化、多元化，复合式液压集成块，即载有板式阀、叠加阀、插装阀等阀体和其它各类附件的液压集成块，已成为目前液压系统发展和应用的主流。

The drawback is that operating torque, operation, easy to make body, stem damage, especially in large-diameter gate valve.

其缺点是操作力矩大，操作时易使阀体、阀杆损坏，特别是大口径闸阀。

Check the valve lift valve is located in the valve body on the valve seat sealing surface.

升降式止回阀的阀瓣座落位于阀体上阀座密封面上。

Lift check valves on the valve seat is located in the valve body sealing surface.

升降式止回阀的阀瓣座落位于阀体上阀座密封面上。

The locking ring surrounds the valve body for permanent attachment to the valve.

锁定环环绕在阀体周围，用于永久性固定在阀门上。

The seat, disc and pivot pins are combined into one subassembly secured to the inlet side of the body with a locking ring in sizes 3 and smaller.

阀座，阀瓣和枢轴销构成一个分总成，采用尺寸3英寸或更小的锁环固定在阀体进口一侧。

The valve is mainly made up of handle, body, disc, locknut and seal etc.

手动密闭闸阀主要由把手、阀体、插板、锁紧螺钉、密封装置等部件组成。

The terminological behavior of high carbon chromium molybdenum steel used for guide pin of delivery valve in aeroengine, as well as the production, constitution and microstructure of hard phases in this material has been studied.

高碳高铬钼合金钢(Cr18Mo16V)具有较高的耐磨性，成为航天、航空和石油化工装置中有关零部件的关键材料之一，而且需要量也越来越大，尤其是用于航空发动机供油系统阀体导销，更表现出了该材料的良好使用性能。

The biggest characteristic of this model is that the hydraulic system pump station, operating console and working clamp installation table can be installed and connected in users sites and dived the test workpiece into the pond, can lift up and down, left and right two directions clamp worktables set 90 degree overturn function, especially suitable for gas pressure test.

本机型最大特点由液压系统泵站，操作控制台和工作夹紧装置台在用户现场安装连接，将试验工件潜入水池中目测，可上下升降，左右两向夹紧工作台设有90度翻转功能，特别适应气体压力试验。◎适用于直通法兰式阀门的密封压力和阀体强度压力性能试验。
