Qhov tseem ceeb ntawm qhov muag muag npauj npaim valve, qhov muag muag npauj npaim valve yog qhov yooj yim hauv cov qauv, me me thiab lub teeb hauv qhov hnyav, thiab tsuas yog muaj ob peb ntu xwb.Thaum lub mos sealing npauj npaim valve yog nyob rau hauv txoj hauj lwm qhib tag nrho, Lub thickness ntawm npauj npaim phaj yog tsuas yog tsis kam thaum lub nruab nrab ntws los ntawm lub valve lub cev, yog li ntawd lub siab poob generated los ntawm lub valve yog me me, yog li nws muaj zoo ntws tswj cov yam ntxwv.Lub mos sealing npauj npaim valve muaj ob hom sealing: elastic sealing. thiab hlau sealing.Elastic sealing valve, lub nplhaib sealing tuaj yeem muab tso rau ntawm lub valve lub cev los yog txuas mus rau qhov chaw ntawm lub phaj npauj npaim.Valves nrog hlau ntsaws ruaj ruaj feem ntau muaj lub neej ntev dua li qub nrog elastic seals, tab sis nws yog ib qho nyuaj rau kev ua tiav. ua tiav foob.Cov hlau foob tuaj yeem hloov mus rau qhov kub ua haujlwm siab dua, thaum lub foob elastic muaj qhov tsis zoo ntawm kev txwv los ntawm qhov kub thiab txias.
Nyob rau hauv cov ntaub ntawv ntawm ob txoj hauj lwm hloov, nqaim txoj kev, tsis tshua muaj suab nrov, cavitation thiab vaporization, ib tug me me npaum li cas ntawm to rau hauv cov huab cua, thiab abrasive media, soft-sealed npauj npaim li qub yuav xaiv tau.Thaum throttling hloov yuav tsum tau nyob rau hauv tshwj xeeb ua hauj lwm tej yam kev mob. , los yog nruj sealing yuav tsum tau, los yog lub mos-foob npauj npaim valve yog siv nyob rau hauv ib tug hnyav abrasion, tsis tshua muaj kub (cryogenic) thiab lwm yam kev ua hauj lwm, nws yog tsim nyog los siv ib tug tshwj xeeb tsim hlau foob nrog ib tug peb-eccentric los yog ob-eccentric kho. ntaus ntawv tshwj xeeb mos sealing npauj npaim valve rau hauv av.
