Npauj npaim li qub yog tsim rau kev khiav dej num. Txij li thaum lub siab poob ntawm npauj npaim valve nyob rau hauv lub raj xa dej yog qhov loj, qhov robustness ntawm npauj npaim phaj kom tiv taus lub siab ntawm cov kav dej nruab nrab thaum kaw yuav tsum tau txiav txim siab. Tsis tas li ntawd, qhov ntsuas kub ntawm kev ua haujlwm ntawm cov khoom siv elastomeric lub rooj zaum ntawm qhov kub siab yuav tsum tau txiav txim siab. Cov txheej txheem ntev thiab tag nrho qhov siab ntawm npauj npaim valve yog me me, qhov qhib thiab kaw nrawm nrawm, thiab nws muaj cov yam ntxwv zoo tswj cov kua dej. Lub hauv paus ntsiab lus ntawm tus npauj npaim valve yog qhov tsim nyog tshaj plaws rau kev ua qhov loj-inch li qub. Thaum npauj npaim valve yuav tsum tau tswj kev ntws, qhov tseem ceeb tshaj plaws yog xaiv qhov loj thiab hom npauj npaim valve kom nws tuaj yeem ua haujlwm tau zoo thiab zoo.
Feem ntau, nyob rau hauv throttling, tswj tswj thiab av nkos xov xwm, nws yuav tsum muaj ib tug luv luv qauv ntev thiab ceev ceev qhib thiab kaw ceev (1/4 tig). Rau qhov tsis tshua muaj siab txiav tawm (qhov sib txawv me me), npauj npaim valve raug pom zoo.
Npauj npaim li qub tuaj yeem siv tau thaum muaj ob txoj haujlwm hloov kho, cov kev txwv nruj, tsis tshua muaj suab nrov, cavitation thiab vaporization phenomena, ib qho me me ntawm cov pa tawm mus rau hauv qhov chaw, thiab cov xov xwm abrasive.
Thaum throttling raug kho raws li kev ua hauj lwm tshwj xeeb, yuav tsum tau nruj sealing, los yog npauj npaim li qub yog siv nyob rau hauv hnyav hnyav, tsis tshua muaj kub (cryogenic) thiab lwm yam kev ua hauj lwm, yuav tsum tau ib tug tshwj xeeb tsim hlau sealing siv kho cuab yeej rau triple eccentricity los yog ob chav eccentricity. npauj npaim valve.
Npauj npaim li qub yog tsim rau cov dej tshiab, dej phwj tuaj, dej hiav txwv, dej ntsev, chav dej, nkev, khoom noj, tshuaj, roj thiab ntau yam khoom uas yuav tsum tau ua kom tiav sealing, xoom gas test to, siab lub neej yuav tsum, thiab kev khiav hauj lwm kub ntawm {{0 }} degrees thiab 150 degrees. Acid-base thiab lwm cov kav dej.
Mos-sealed eccentric npauj npaim li qub yog tsim rau bidirectional qhib, kaw thiab kho qhov cua thiab plua plav tshem tawm cov kav dej. Lawv tau siv dav hauv cov kav dej thiab cov dej hauv metallurgy, lub teeb kev lag luam, hluav taws xob fais fab, thiab petrochemical systems.
Hlau-rau-hlau hlau kaw ob chav eccentric npauj npaim valve yog tsim rau hauv nroog cua sov, roj, dej thiab lwm yam roj, roj, kua qaub thiab alkali pipelines, thiab lwm yam., raws li ib tug regulating thiab throttling ntaus ntawv.
Ntxiv rau kev siv raws li kev tswj hwm li qub rau qhov loj-loj siab viav vias adsorption (PSA) cov roj sib cais, cov hlau-rau-hlau nto kaw triple eccentric npauj npaim li qub tuaj yeem siv dav hauv roj av, petrochemical, tshuaj, metallurgy, hluav taws xob fais fab. thiab lwm yam teb. Lawv yog cov kev xaiv zoo tshaj plaws rau lub rooj vag li qub thiab lub ntiaj teb li qub. khoom hloov.
