Lub teb chaws tus qauv siv dav tshaj plawsrooj vag valveyog lub rooj vag valve.Nws cov yam ntxwv tshwj xeeb yog tias ob qhov chaw sib khi ntawm lub rooj vag qhov rooj thiab qhov chaw sib khi ntawm ob qhov kev taw qhia ntawm lub valve lub cev tsim ib khub sealing kom ua tiav cov nyhuv sealing.Nws cov qauv yog qhov yooj yim, thiab cov kua dej me me, thiab nws feem ntau siv rau kev thauj mus los ntev, cov kav dej thiab cov khoom siv rau dej, roj, roj thiab lwm yam xov xwm.Lub hom phiaj ntawm kev siv lub qhov rooj vag yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawmThaum kaw, tig lub valve qia clockwise kom lub sealing nto ntawm lub qhov rooj valve thiab lub sealing nto ntawm lub valve lub cev nyob ze kom ua tau ib tug foob.Txawm li cas los xij, lub foob tshwj xeeb ntawm qhov kawg ntawm qhov kawg ntawm cov hlau kaw lub qhov rooj valve uas tsim los ntawm kev txiav txim siab feem ntau tsis txaus kom ua tiav qhov kawg ntawm lub foob.Yog li ntawd, cov hlau-sealed hom rooj vag valve yog ib leeg-sided yuam foob.
Siv sijhawm sijhawm ntawm hom rooj vag valve:
Lub peev xwm ntawm daim ntawv thov thiab cov yam ntxwv ntawm lub teb chaws tus qauv wedge valve, ntawm ntau hom li qub, lub rooj vag valve yog qhov siv dav tshaj plaws.Nws yog feem ntau tsuas yog haum rau tag nrho qhib lossis kaw tag nrho, thiab tsis tuaj yeem siv rau kev hloov kho thiab throttling.
Hom rooj vag li qub feem ntau yog siv nyob rau hauv lub sijhawm uas tsis muaj qhov yuav tsum tau nruj rau sab nraud qhov ntev ntawm lub valve, thiab kev siv cov xwm txheej kuj hnyav heev.Xws li kev ua haujlwm nruab nrab ntawm qhov kub thiab txias siab, nws yog qhov yuav tsum tau kaw qhov chaw yuav tsum tau muab kaw kom ntev.
Feem ntau, cov kev siv los yog cov kev cai yuav tsum tau txhim khu kev ruaj ntseg sealing kev ua tau zoo, siab siab, siab siab txiav-tawm (loj siab sib txawv), tsis tshua muaj siab txiav-tawm (me me siab sib txawv), tsis tshua muaj suab nrov, cavitation thiab vaporization, siab kub nruab nrab, tsis kub. (cryogenic), nws raug nquahu kom siv Wedge gate valve.Xws li kev lag luam hluav taws xob hluav taws xob, roj av refining, petrochemical kev lag luam, offshore roj, dej engineering thiab dej phwj kho engineering hauv nroog tsim, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam.
