Hlau Seated Bi-directional Npauj Npaim Valve
Cov ntsiab lus ntawm ob chav eccentric qauv
Thawj eccentricity - Offset ib qho kev ncua deb ntawm lub centerline ntawm lub sealing lub rooj thiab lub centerline ntawm lub valve qia.Ua kom lub valve sealing lub rooj ua tiav.
Qhov thib ob eccentricity - Lub valve qia centerline yog offset los ntawm ib qho kev ncua deb ntawm lub valve lub cev (los yog bore) centerline.Nyob rau tib lub sijhawm, ntawm lub phaj, qhov nruab nrab ntawm lub qhov taub uas nruab lub qia valve yog offset tib qhov kev ncua deb tshaj li lub voj voog sab nraud centerline sab nraum lub phaj npauj npaim.
Kev ua haujlwm ntawm ob chav eccentric qauv
Thaum lub phaj npauj npaim yog nyob rau hauv tus txheej txheem ntawm / tawm lub valve thiab lub valve yog nyob rau hauv tag nrho qhib lub xeev, lub sealing nto yog kiag li detached, tshwj xeeb tshaj yog ib tug loj sib txawv nyob ze ntawm lub sealing lub rooj ntawm lub valve qia, thiaj li yuav txo tau cov hnav thiab puas. ntawm lub valve sealing nto, tiv thaiv lub ntsiab foob roj hmab nplhaib ntawm npauj npaim valve, thiab txuas lub neej kev pab cuam.
Cov yam ntxwv ua haujlwm
1.Unique elastic hlau sealing nplhaib qauv tsim los xyuas kom meej isobaric bi-directional sealing kev ua tau zoo, txhim khu kev qha sealing kev ua tau zoo;
2.Siv cov qauv semi-axial nrog qhov loj hla qhov chaw thiab cov dej ntws me me;
3.Siv ob chav eccentric qauv, lub valve lub cev sealing nto yog kiag li detached los ntawm lub valve phaj sealing nto tom qab qhib, tsis muaj kev sib txhuam, lub neej ntev;
4.Me me, lub teeb yuag, lub teeb ua haujlwm;
5. Kab rov tav mounting phau ntawv valve muaj bi-directional zaub muaj nuj nqi, qhib lub xeev ntawm lub valve tuaj yeem pom synchronously los ntawm kev khiav hauj lwm nto thiab sab.
Siv tau nruab nrab
Siv dav hauv kev siv dej thiab dej, metallurgy, roj av, tshuaj lom neeg kev lag luam, hluav taws xob hluav taws xob, kev tsim kho hauv nroog thiab lwm yam kev lag luam pipelines los txiav tawm, txuas thiab tswj kev siv nruab nrab.
