4、啟式止回閥相比,提高使用壽命57截流封閉性能好。逆止口與閥板之間為橡膠軟密封。5、 運(yùn)行平穩(wěn)、無震動(dòng)、噪音低。6、 維修費(fèi)用低。與旋啟式止回閥相比,降低維修費(fèi)用80%。1 .Energysaving:sincethevalveplatewithalightbodystructure(rubberandmetalcompositestructure),thereisacounterweight,thelocalresistanceissmall,bigopen-degreeComparedwithswingcheckvalves5conveyorperthousandtonsofwatercan

8、的開啟間隙,這樣介質(zhì)可以通過,減弱了水錘峰值壓力,限制了破壞性水錘的發(fā)生。閥板壓在活塞端部,活塞腔內(nèi)的水阻礙了活塞的快速回伸,阻止閥板的關(guān)閉,這時(shí)閥板在介質(zhì)的背向壓力作用下,推動(dòng)活塞向后滑移,在活塞的推動(dòng)下,活塞里介質(zhì)通過調(diào)節(jié)閥又回到了系統(tǒng)中,活塞也緩慢回到原來位置,閥板最終完全關(guān)閉。l.thecheckvalveconsistsofvalvebody,valvecover,valveplateassembly,thecounterweight,thepistonassemblyandtheneedlevalveandothercomponents.Whenstartthepump,relyi

13、意的是:活塞伸出的長(zhǎng)短的調(diào)整與供水壓力,輸水距離,相對(duì)高差等工況有很大關(guān)系,它們之間是成正比例關(guān)系。另外,緩閉時(shí)間的長(zhǎng)短,還可用針型調(diào)節(jié)閥的開度大小來控制,這個(gè)時(shí)間可控制在0Y0秒,或者更長(zhǎng)些。Extendingthelengthofthepistontoadjustthesizeofthevalveopening,thecontrolpistonchamberandthevalveplateclosingcapacityextensionSlowtime.Slowclosingtheopeningofalarge,longdischargetime,waterhammersmall;othe
