Npauj npaim valveyog ib hom valve uas siv lub disc qhib thiab kaw cov tswv cuab rau reciprocate txog 90 ° qhib, kaw los yog kho qhov ntws ntawm qhov nruab nrab.Npauj npaim valve tsis tsuas yog muaj cov qauv yooj yim, me me, lub teeb yuag, tsis siv cov khoom siv, me me installation loj, me me tsav torque, yooj yim thiab ceev khiav lag luam, tab sis kuj muaj kev khiav dej num zoo thiab kaw sealing yam ntxwv tib lub sij hawm.Nws yog ib qho ntawm qhov loj tshaj plaws valve ntau yam hauv kaum xyoo dhau los.Npauj npaim li qub tau siv dav hauv ntau qhov kev lag luam.Qhov ntau thiab ntau ntawm nws cov kev siv tseem nthuav dav, thiab nws tab tom txhim kho mus rau qhov kub thiab txias, kev kub siab, txoj kab uas hla loj, kev ua haujlwm siab sealing, lub neej ntev, kev hloov kho zoo heev, thiab ntau txoj haujlwm ntawm ib lub valve.Nws txoj kev ntseeg siab thiab lwm yam kev ntsuas kev ua tau zoo tau mus txog qib siab.
Nrog rau daim ntawv thov ntawm chemically resistant hluavtaws roj hmab ntawm npauj npaim valve, kev ua tau zoo ntawm npauj npaim valve tau zoo tuaj.Txij li cov roj hmab hluavtaws muaj cov yam ntxwv ntawm kev tiv thaiv corrosion, yaig tsis kam, qhov ruaj khov, zoo resilience, yooj yim tsim, thiab tus nqi qis, hluavtaws roj hmab nrog cov khoom sib txawv tuaj yeem xaiv raws li kev siv sib txawv kom tau raws li kev ua haujlwm ntawmnpauj npaim li qub.
Vim hais tias polytetrafluoroethylene (PTFE) muaj zog corrosion kuj, ruaj khov kev ua tau zoo, tsis yooj yim rau lub hnub nyoog, tsis tshua muaj kev sib txhuam coefficient, yooj yim rau kev tsim, thiab ruaj khov nyob rau hauv loj, thiab nws cov khoom muaj peev xwm tuaj yeem txhim kho los ntawm kev sau thiab ntxiv cov ntaub ntawv tsim nyog, ua rau lub zog zoo dua thiab kev sib txhuam.Npauj npaim valve sealing khoom nrog qis coefficient overcomes cov kev txwv ntawm hluavtaws roj hmab, yog li cov ntaub ntawv polymer sawv cev los ntawm PTFE thiab nws cov ntaub ntawv sau thiab hloov kho tau siv dav hauv npauj npaim li qub, kom ua tau zoo ntawm npauj npaim li qub.Npauj npaim valve nrog qhov kub thiab txias ntau yam, txhim khu kev qha sealing kev ua tau zoo thiab ntev kev pab cuam lub neej tau raug tsim.
Yuav kom ua tau raws li daim ntawv thov ntawm qhov kub thiab txias, muaj zog yaig, lub neej ntev thiab lwm yam kev siv hauv kev lag luam,hlau kaw npauj npaim li qubtau tsim kho zoo heev.Nrog rau daim ntawv thov ntawm kub tsis kam, tsis kub tsis kam, muaj zog corrosion kuj, muaj zog yaig kuj, thiab high-strength alloy cov ntaub ntawv nyob rau hauv npauj npaim li qub, hlau-sealed npauj npaim li qub tau lug siv nyob rau hauv industrial teb xws li kub thiab tsis kub, muaj zog. erosion, thiab lub neej ntev.
Thaum npauj npaim valve qhib tag nrho, nws muaj qhov tsis txaus txaus.Thaum qhib qhov nruab nrab ntawm 15 ° thiab 70 °, rhiab txaus tswj tuaj yeem ua tau, yog li nyob rau hauv qhov kev hloov pauv loj, daim ntawv thov ntawm npauj npaim li qub yog ntau heev.
Vim tias qhov txav ntawm lub phaj npauj npaim yog so, feem ntau npauj npaim li qub tuaj yeem siv rau kev tshaj tawm nrog cov khoom raug tshem tawm.Nyob ntawm lub zog ntawm lub foob, nws kuj tuaj yeem siv rau cov hmoov thiab granular media.
Npauj npaim li qub yog tsim rau kev khiav dej num.Vim tias qhov poob siab ntawm npauj npaim valve hauv cov yeeb nkab yog qhov loj, uas yog li peb npaug ntawm qhovrooj vag valve, thaum xaiv lub npauj npaim valve, qhov cuam tshuam ntawm lub siab poob ntawm lub raj xa dej yuav tsum tau txiav txim siab tag nrho, thiab lub zog ntawm lub phaj npauj npaim kom tiv taus qhov siab ntawm cov kav dej nruab nrab yuav tsum tau txiav txim siab thaum nws raug kaw.Tsis tas li ntawd, qhov kev txwv kub ntawm kev ua haujlwm ntawm cov khoom siv elastomeric ntawm qhov kub siab yuav tsum tau txiav txim siab.
Npauj npaim li qub muaj cov qauv me me ntev thiab qhov siab tag nrho, qhib thiab kaw nrawm, thiab cov yam ntxwv tswj dej zoo.Lub hauv paus ntsiab lus ntawm npauj npaim valve yog qhov tsim nyog tshaj plaws rau kev ua qhov loj-inch valve.Thaum npauj npaim valve yuav tsum tau siv rau kev tswj ntws, qhov tseem ceeb tshaj plaws yog xaiv cov lus qhia thiab hom npauj npaim valve kom nws tuaj yeem ua haujlwm tau zoo thiab zoo.
Feem ntau, nyob rau hauv throttling, regulating tswj thiab av nkos nruab nrab, nws yuav tsum muaj luv luv qauv ntev, ceev qhib thiab kaw ceev, tsis tshua muaj siab txiav-tawm (me me siab sib txawv), thiab npauj npaim valve yog pom zoo.Npauj npaim valve tuaj yeem siv rau hauv ob txoj haujlwm hloov kho, txo txoj kab uas hla channel, tsis tshua muaj suab nrov, cavitation thiab vaporization, me me ntawm cov pa tawm mus rau qhov chaw, thiab nruab nrab abrasive.Npauj npaim valve tseem tuaj yeem siv rau kev hloov pauv hauv kev ua haujlwm tshwj xeeb, lossis siv nyob rau hauv kev ua haujlwm xws li kev sib khi nruj, hnav hnyav, tsis tshua muaj kub (cryogenic), thiab lwm yam.
