详细信息

概述

固定球阀的球体,采用上、下两根阀杆固定,工作时,流体压力不会使球体向阀座移动,阀座不会承受过大压力而变形。阀杆部份设有自润滑轴承,减少磨擦,开关扭距小,两阀座均采用弹簧设预紧。密封采用聚氟乙烯镶入钢圈内,钢圈后部设有弹簧,保证阀座紧贴球体。当阀门中腔压力异常升高超过弹簧顶紧力,阀座后退脱离球体,达到自动泄压效果,压后阀座自动复位。结构的性使固定球阀的密封性能稳定操作省力,使用寿命长,极适用于长输管线和一般管线。


Summary

The sphere of Q47 type standing ball valve is fixed with upper and lower valve stems. When it works, for fluid pressure is unable to make sphere move towards valve base, the valve base won't be deformed for enduring over pressure.  There is self-lubricating bearing seton the part of valve stem to reduce friction, and its switch-torque is small. Both valve bases are pertensioned  by setting spring. Referring to sealing, adopt the way to inset polytetrafluoroethylene into steel-ring  with a spring on  its  rear end, which can ensure valve base cling to sphere. When the cavity pressure in valve transnormally excesses spring tension, valve base will back off and separate from sphere to get the effect of automatic pressure release.The valve base will automatically reset after being pressed.  Thanks to advanced structure, the standing ball valve has stable sealing performance, labor-saved operation and long using life. It is es-pecially applicable for long conveymg pipeline and general pipeline.

全通径设计

按照客户的要求可以提供全通径

或缩径阀门,全通径阀门具有与管子

内径一致的通道直径,减少涡流

便于清扫管道。

Full bore design

According to the customer's

demand,the fullbore orthe redu-

ced bore can be provided. The f-

ull bore valve has the diameter of

channel completely equalto the

 in ner diameter of pipe to facilitat-

e to clean the pipe.

Block & Bleed Function

 Fixed ball valve adopts spri-

ng to pretighten.And seat sealis

double pistons.lt adopts piston p-

rinciple to seaI.Upstr-Eam and d-

ownstream seats make fluid stop.

And the emptying valve installed

on the middle cavity is used to e-

mpty and the blowdown valve in-

stalled at the bottom of valve to c-

lear off dirt to facili-tate to clean

the pipe.







防火结构

万一发生火灾或异常升温使PT

FE软化烧损时,阀座支承圈防火密封

符合AP1607和AP16FA

Fire-proof structure

When the fire happens orthe

temperatue unusually rises to m-

ake PTFE soften to damage.the

fireproof sealsurface of seat su-

pported circle can contact with b-

all to have seal function.This co-

nforms to therequirements of A-

Pl 607 and AP16FA.


防静电设计

采用铬镍不锈钢的弹簧和小球使

球体、阀杆和阀体之间相互导电,从

而把静电释放。
