闸杆

The key point of the structure of the utility model is that: the other side of the reducer that is arranged on the platform is provided with a hoisting device; the roller shaft end of the electronic controlled windlass is provided with a hub, a damper brake is arranged outside the hub; the input castellated shaft of the reducer that is arranged on the electronic windlass is provided with duplicate gears that have different amount of teeth.

本实用新型包括标准节，两侧标准节的中间为平台，电控卷扬机的卷绳通过平台上的滑轮同吊盘相连；平台上的减速器的一侧设置有可提升平台的具有卷绳的滚筒，平台上设置有具有滑轮的支架，其结构要点平台上的减速器的另一侧设置有提升装置；电控卷扬机的滚筒轴端设置有轮毂，轮毂外设置有制动闸；电控卷扬机的减速器的输入花键轴上设置具有不同齿数的双连齿轮，双连齿轮之间的凹槽内的拨杆同减速器外的摇把相连。

As the brake lever and shifter are one unit, there are two versions, one for cable brakes and one for hydraulic disc brakes.

由于变速拨杆与刹车把是一体化结构，所以分别有油碟版和拉线版两种闸变版本可选。

In a normal pipe ram, the two blocks of steel that meet in the center of the wellbore to seal the well have a hole (one-half of the hole on each piece) through which the pipe fits.

在标准的管闸板中，在井眼中间相会，以密封井的两块钢板有一个可以通过钻杆的中孔。

The feed screw is locked and the truck can't be moved when the VCB is closed.

当断路器合闸时，丝杆被锁定，不能移动手车。

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。

This provides vertical movement of the gate without extension of the stem above the valve body.

因此闸板的垂直移动不会导致阀杆在阀体上方的延伸。

The most important are as follows: Detection of type: valve stem seal leakage test and test; water valve tightness test; switch tightness test; the take-off safety valve Test; Detection Object: valve, the cut-off valve , safety valve, throttle valve, check valve, swing check valve, ball valve, regulating valve and other hollow pump body, valve body and housing, etc.; way valve connection: flange connection, threaded connection, welding connection; detection medium.

最重要的有以下几种：检测类型：阀门密封性试验及阀杆泄漏性试验；水中阀体密封性试验；开关密封性试验；安全阀的起跳值试验；检测对象：闸阀、截止阀、安全阀、节流阀、止回阀、摆动式逆止阀、球阀、调节阀和其他中空的泵体、阀体和壳体等；阀门联接方式：法兰联接、螺纹连接、焊接联接；检测介质。

Clearly, in order to provide sealing damper force, stem nut torque transmission valve operations than the big moment in the process.

显然，为了向闸板提供密封力，阀杆螺母传递的力矩比阀门操作过程中的力矩大。

D. The shear blind rams are designed to cut through the drill pipe and seal the hole.

D。 把剪切式全封闸板防喷器设计成剪断钻杆并密封井眼。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.
