概述 固定球閥的球體,采用上、下兩根閥桿固定,工作時(shí),流體壓力不會(huì)使球體向閥座移動(dòng),閥座不會(huì)承受過(guò)大壓力而變形。閥桿部份設(shè)有自潤(rùn)滑軸承,減少磨擦,開(kāi)關(guān)扭距小,兩閥座均采用彈簧設(shè)預(yù)緊。密封采用聚氟乙烯鑲?cè)脘撊?nèi),鋼圈后部設(shè)有彈簧,保證閥座緊貼球體。當(dāng)閥門中腔壓力異常升高超過(guò)彈簧頂緊力,閥座后退脫離球體,達(dá)到自動(dòng)泄壓效果,壓后閥座自動(dòng)復(fù)位。結(jié)構(gòu)的性使固定球閥的密封性能穩(wěn)定操作省力,使用壽命長(zhǎng),極適用于長(zhǎng)輸管線和一般管線。 | 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. |

| 全通徑設(shè)計(jì) 按照客戶的要求可以提供全通徑 或縮徑閥門,全通徑閥門具有與管子 內(nèi)徑一致的通道直徑,減少渦流 便于清掃管道。 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. 阻塞與排泄功能 固定球閥采用彈簧預(yù)緊,閥座密 封為雙活塞.利用話塞原理密封.上 下游側(cè)的閥座使流體阻斷.閥體中腔 裝放空閥排空,閥底裝有排污閥排污, 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. | | 防火結(jié)構(gòu) 萬(wàn)一發(fā)生火災(zāi)或異常升溫使PT FE軟化燒損時(shí),閥座支承圈防火密封 面可以和球體接觸.起到密封作用且 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. 防靜電設(shè)計(jì) 采用鉻鎳不銹鋼的彈簧和小球使 球體、閥桿和閥體之間相互導(dǎo)電,從 而把靜電釋放。 Anti-static design Chrome and nickelstainless- teel spring and small ball are ad- opted to make electroconductive among ball.
