?进口锻钢截止阀描述--

RETZ锻钢截止阀的闭合原理是,依靠阀杠压力,使阀瓣密封面与阀座密封面紧密贴合,阻止介质流通。截止阀只许介质单向流动,安装时有方向性

The closing principle of RETZ forged steel cut-off valve is that the valve sealing surface and valve seat sealing surface are closely linked by the pressure of the valve bar to prevent the flow of medium. The shut-off valve only allows one-way flow of medium and has directivity when installed.

?进口锻钢截止阀特征--

全径或缩径,明杆支架式

整体式阀体或焊接式体

阀瓣可变换为节流型、针型、球型和止回型

阀体和零件全部锻钢更加坚固,可耐高温高压

阀杆行程短,启闭迅速

Full diameter or shrinkage

Integral body or welded body

The disc can be changed into throttling, pin, ball and check type.

All valves and parts are forged steel more sturdy, resistant to high temperature and high pressure.

Short stem stroke, quick opening and closing

?进口锻钢截止阀结构--

锻钢截止阀有三种盖设计形式。

1.种是螺栓式阀盖,按这种设计形式设计的阀门,其阀体与阀盖用螺栓螺母连接,缠绕式垫片(316夹柔性石墨制造)密封。客户有特殊要求时也可采用金属环连接。

2.第二种设计形式是焊接式阀盖,按这种设计形式的阀门,其阀体与阀盖用螺纹连接,全焊密封。客户有特殊要求时也可采用全焊透连接。

3.第三种是压力自紧式阀盖,按这种设计形式设计的阀门,其阀体与阀盖用螺纹连接,内压自密环密封。
