Groove Flanged Npauj Npaim Valve

Npauj npaim valve yog ib yam ntawm lub valve uas siv disc hom qhib thiab kaw qhov chaw tig rov qab mus txog 90 ° qhib, kaw lossis kho qhov ntws 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 thiab sealing yam ntxwv tib lub sijhawm.Npauj npaim li qub tau siv dav.

Nrog rau daim ntawv thov ntawm chemically resistant hluavtaws roj hmab ntawm npauj npaim li qub, kev ua tau zoo ntawm npauj npaim li qub tau txhim kho.Txij li cov roj hmab hluavtaws muaj cov yam ntxwv ntawm kev tiv thaiv corrosion, yaig tsis kam, ruaj khov loj, zoo resilience, yooj yim tsim, thiab tus nqi qis, hluavtaws roj hmab nrog cov khoom sib txawv tuaj yeem xaiv raws li cov ntawv thov sib txawv kom tau raws li kev ua haujlwm ntawm npauj 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 cov duab, ruaj khov loj, thiab nws cov kev ua tau zoo tuaj yeem txhim kho los ntawm kev sau thiab ntxiv cov khoom tsim nyog kom tau txais lub zog zoo dua thiab kev sib txhuam.Npauj npaim valve sealing cov ntaub ntawv nrog qis coefficient kov yeej cov kev txwv ntawm cov roj hmab hluavtaws.Yog li ntawd, cov ntaub ntawv siab molecular polymer sawv cev los ntawm polytetrafluoroethylene thiab lawv cov ntaub ntawv hloov kho tau siv dav hauv npauj npaim li qub, kom ua tau zoo ntawm npauj npaim li qub tuaj yeem txhim kho.Nws tau raug txhim kho ntxiv, thiab npauj npaim valve nrog qhov kub thiab txias ntau yam, txhim khu kev qha sealing kev ua tau zoo thiab kev pab lub neej ntev dua tau tsim.

Txhawm rau ua kom tau raws li qhov yuav tsum tau muaj ntawm cov ntawv thov kev lag luam xws li qhov kub thiab txias, muaj zog yaig, thiab lub neej ntev, cov hlau nplaum npauj npaim li qub tau tsim zoo heev.Nrog rau daim ntawv thov ntawm kub tsis kam, tsis kub tsis kam, muaj zog corrosion kuj, muaj zog corrosion 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 siab thiab tsis kub, muaj zog. erosion, thiab lub neej ntev.Npauj npaim li qub nrog txoj kab uas hla loj (9 ~ 750 hli), siab siab (42.0 MPa), thiab qhov kub ntawm qhov dav (-196 - 606 ° C) tau tshwm sim.

Thaum lub npauj npaim valve qhib tag nrho, nws muaj qhov ua haujlwm me me.Thaum qhov qhib yog nyob nruab nrab ntawm 15 ° ~ 70 °, nws tuaj yeem ua tau rhiab txaus tswj, yog li nyob rau hauv lub tshav pob ntawm txoj kab uas hla loj, daim ntawv thov ntawm npauj npaim li qub yog ntau heev.

Txij li thaum lub zog 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.Txij li thaum lub siab poob ntawm npauj npaim valve nyob rau hauv cov yeeb nkab yog qhov loj, kwv yees li peb zaug ntawm lub rooj 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 valve. npauj npaim phaj kom tiv taus lub siab ntawm cov kav dej nruab nrab thaum nws raug kaw yuav tsum tau txiav txim siab..Tsis tas li ntawd, qhov kev txwv ntawm kev ua haujlwm kub ntawm cov khoom siv lub rooj zaum elastic ntawm qhov kub thiab txias yuav tsum tau txiav txim siab.

Cov qauv 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 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, npauj npaim li qub tau pom zoo rau kev throttling, kev tswj hwm thiab av nkos xov xwm qhov ntev ntawm cov qauv, qhib thiab kaw ceev ceev, thiab tsis tshua muaj siab txiav tawm (qhov sib txawv me me) yuav tsum tau.Npauj npaim li qub tuaj yeem xaiv tau rau kev hloov pauv ob txoj haujlwm, txo txoj kab uas hla, tsis tshua muaj suab nrov, cavitation thiab vaporization, me me ntawm cov pa tawm mus rau qhov chaw, thiab cov xov xwm abrasive.Throttle hloov nyob rau hauv tshwj xeeb kev ua hauj lwm tej yam kev mob, los yog ua hauj lwm tej yam kev mob uas yuav tsum tau nruj sealing, hnyav hnyav, tsis tshua muaj kub (cryogenic) thiab lwm yam.
