Npauj npaim valve txais ib lub qauv uas lub valve phaj tig raws cov kab nruab nrab, yog li lub valve yog me me. Lub valve tuaj yeem qhib tau los ntawm kev tig tus kov 90 degrees lossis tsav los ntawm lub iav iav kom lub valve phaj sib npaug mus rau qhov nruab nrab ntws. Yog li ntawd, npauj npaim valve muaj cov yam ntxwv ntawm cov qauv yooj yim, me me, lub teeb yuag, me me installation loj, yooj yim khiav lag luam, thiab qhib thiab kaw sai. Nws kuj muaj cov yam ntxwv sealing thiab ntws tswj. Txawm li cas los xij, vim muaj qhov ua haujlwm loj ntawm lub valve disc, qhov nruab nrab siab muaj kev cuam tshuam zoo rau kev qhib thiab kaw ntawm lub valve, yog li nws tsis haum rau qhov chaw siab. Yav dhau los, npauj npaim li qub tau txwv los ntawm kev siv thev naus laus zis thiab cov khoom sib khi, thiab feem ntau ntawm cov qauv yog mos cov ntsaws ruaj ruaj ntawm cov kab hauv nruab nrab, uas yog, lub rooj zaum valve feem ntau yog cov roj hmab, yas, thiab cov phaj npauj npaim yog hlau lossis hlau npog nrog. roj hmab los yog yas. Nyob rau hauv xyoo tas los no, nrog kev txhim kho sai ntawm kev tshawb fawb thiab thev naus laus zis, npauj npaim li qub tau tsim cov qauv tshiab, thiab eccentric hlau sealing npauj npaim valve yog ib qho ntawm lawv. Lub rooj zaum valve thiab npauj npaim phaj sealing nto ntawm eccentric hlau sealing npauj npaim valve yog ua los ntawm cov khoom siv hlau carbide, los yog lub phaj npauj npaim yog ua los ntawm cov ntaub mos mos thiab cov nqaij, yog li ntawd lub npauj npaim valve tuaj yeem tiv taus kub, tsis tshua muaj kub, puas. , yaig, zoo sealing kev ua tau zoo, thiab kev pab lub neej ntev, yog li nws yog dav siv.
