Hydraulic Valve Tappet Removal/Installation Tool
液压阀推杆拆卸/安装工具
2.
Instead, the motor rotate reversely, push rod (piston rod) push out, the valve plate closes, stops discharging.
反之，电机反转，推杆（活塞杆）推出，阀板关闭，停止卸料。
3.
When the handwheel is rotated to the closed position the upper stem pushes on the diaphragms, which deflect downward, forcing the lower stem against the valve seat.
当手轮旋转到关闭位置，上阀杆推动横膈膜，横膈膜下垂，迫使下阀杆接触阀座。
4.
When the handwheel is rotated toward the open position the upper stem is moved away from the diaphragms allowing the spring to push the lower stem away from the seat.
当手轮象开启位置旋转时，上阀杆离开横膈膜，弹簧推动下阀杆离开阀座。
5.
The lower stem is physically pulled away from the seat instead of being lifted away by the spring.
下阀杆是被从阀座上物理地推开，而不是被弹簧举起来。
6.
When discharging, the motor operates, hydraulic cylinder charges pressure, push rod (piston rod) draw back, the valve plate connected with push rod opens, the materials are discharged.
当需要卸料时，电机运转，液压缸增压，推杆（活塞杆）收回，和推杆连接的阀板开启，物料卸下。
7.
Because a push-rod valve train has additional parts, it is more difficult to run at high speeds.
因为推杆气阀传动有另外的部分，所以很难以高速运转。
8.
This valve should be installed vertically, before the use should check whether the push rod is flexible, electrical installation and connection are correct.
本阀垂直安装，使用前应检查推杆是否灵活，电气安装连接是否正确。
9.
Debug the reversing of the valve according to the control principle of electric and electric hydraulic draw stem.
根据电动、电液推杆控制原理调试盲板阀换向状态。

Stem– precision machined stem has a backseat design.
(11) 阀杆-精加工阀杆配置后座结构。
12.
The cylinder head carries the valves, valve springs and the rockers on the rocker shaft, this part of the valve gear being worked by the push-rods.
气缸盖携带阀门，气门弹簧和在摇臂杆上的摇臂，这部分的气门传动机构通过推杆工作。
13.
Remove the relief valve cover, stem/diaphragm assembly, and relief valve spring.
拆卸安全阀阀盖，阀杆/隔膜总成，和安全阀弹簧。
14.
The lower stem is encased in a spring which forces the stem away from the seat when the valve is opened.
下阀杆包裹在一个弹簧内部，当阀门开启时，弹簧迫使阀杆离开阀座。
15.
Stem bearing to assure concentric stem rotation, allowing stem packing to provide maximum sealing effectiveness.
阀杆轴承保证同轴阀杆的旋转，使得阀杆填料具有最大的密封效果。
16.
In all designs, the valve stem normally serves as a piston rod with disc fastened directly to them.
在所有结构中，阀杆通常作为活塞杆，阀瓣直接固定在阀杆上。
17.
"Primary uses for wrot brass are for ball valve stems and balls, and iron valve stems. a forging grade of brass is used in ball valve bodies and pieces."
黄铜的主要用途是球阀阀杆和球体,和铸铁阀门的阀杆。可锻黄铜可用于球阀阀体和断口部件。
