The production practice proves that this welding device has acheived good effect in the production of YSP 15 liquidized petroleum steel bottle and it is a general and low cost welding device for automatical welding production of liquidized petroleum steel bottle valve base.

介绍了 YSP-15型钢瓶瓶阀座自动焊接装置的结构、组成、工作原理及设计的主要特点。

Through analysis of the oil-seat oiling parts of the structure and characteristics of the processing requirements of the development of a more reasonable fixture design, so as to guarantee the precision machining of parts will provide an economical and practical technology equipment, has some practical value.

本文通过分析注油器油阀座零件的结构特点和加工要求，制定了一套较合理的夹具设计，从而为保证该零件的加工精度将提供一种经济实用的工艺装备，具有一定的实用价值。

Wedgetorque operator lifts, rotates 90o and reseats plug on its protected seating surfaces.

Wedgetorque操作机构提升，旋转90o，并且重新复位阀塞到其受到保护的阀座密封面内。

It has special unitized construction which consists of the seat, disc and stem assembly, and strainer screen all together in one unit for complete replacement maintenance.

它具有特殊的整体结构，由阀座，阀瓣和阀杆总成，以及过滤器网等整合在一个整体中，完全能够进行更换维护。

Once seating or unseating thrust has been calculated, the torque can be obtained by the formula

一旦计算出启闭阀门时的阀座推力，则扭矩也可以从下列公式得到

Thrust is the purely linear push-pull force involved in seating and unseating a valve.

推力是阀门在开启和关闭时阀座上产生的纯粹线性推力或拉力。

Running rimpull can be calculated by substituting running for seating/unseating torque.

用运行扭矩替代启闭阀门的阀座扭矩，可以计算出运行边缘拉力。

The flushing action is achieved as the compressed purge media is released to become the flush media when the plug unseats.

当阀塞离开阀座位置时，被压缩的清洗流体介质变成冲刷流体介质，实现冲刷作用。

Check wet alarm valve valve seat valve components and the question of whether Mifengbuyan, so that large amounts of water into the retarder.

检查湿式报警阀阀瓣组件与阀座之间是否密封不严，使大量的水进入延迟器。

When the pressure is low, the role of Poppet head pressure sufficient to overcome the pressure regulator spring force, Poppet Head is closed at this time there is no pressure on the oil through the damping holes on the balance of the piston movement, so a balance piston, the next two cavity pressure equal, balanced piston under the action of the spring force gently on the top of the seat, pressure port and overflow port unreasonable.

当压力较低时，作用在提动头上的压力不足以克服调压弹簧力，提动头处于关闭状态，此时没有压力油通过平衡活塞上的阻尼孔流动，故平衡活塞上、下两腔压力相等，平衡活塞在弹簧力的作用下轻轻地顶在阀座上，压力口和溢流口不通。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
