A npauj npaim valveyog ib hom valve uas tuaj yeem qhib lossis kaw los ntawm tig rov qab thiab tawm ntawm 90 degrees. Covnpauj npaim valveua tau zoo nyob rau hauv cov nqe lus ntawm kev khiav dej num nyob rau hauv tas li ntawd mus rau muaj zoo kaw thiab sealing muaj peev xwm, yooj yim tsim, me me, lub teeb yuag, tsis siv cov khoom, yooj yim installation, tsis tshua muaj tsav torque, thiab ceev ceev. ib qho ntawm feem ntau ceev valve hom.Npauj npaim li qub feem ntau siv. Qhov ntau thiab dav ntawm lawv cov kev siv tau nthuav dav, thiab lawv tau siv ntau dua rau qhov kub thiab txias, kev kub siab, txoj kab uas hla loj, kev sib khi siab, lub neej ntev, kev hloov kho tshwj xeeb, thiab ntau qhov kev ua haujlwm li qub. Tam sim no nws muaj qib siab ntawm kev cia siab thiab lwm yam kev ua tau zoo.

Kev ua haujlwm ntawm npauj npaim li qub tau txhim kho ua tsaug rau kev siv cov roj hmab hluavtaws hluavtaws. Txij li cov roj hmab hluavtaws muaj qhov zoo ntawm kev tiv thaiv corrosion, yaig tsis kam, ruaj khov loj, zoo resilience, yooj yim ntawm kev tsim, thiab tus nqi qis, hluavtaws roj hmab uas muaj ntau yam khoom tuaj yeem xaiv raws li ntau yam kev thov kom ua tau raws li kev ua haujlwm ntawm npauj npaim li qub.

Txij li thaum polytetrafluoroethylene (PTFE) muaj qhov muaj zog tiv thaiv corrosion, kev ua haujlwm ruaj khov, ua haujlwm rau kev laus, tsis tshua muaj coefficient ntawm kev sib txhuam, yooj yim ntawm shaping, thiab ruaj khov ntawm qhov loj, nws qhov kev ua tau zoo tag nrho tuaj yeem txhim kho los ntawm kev sau thiab ntxiv cov ntaub ntawv tsim nyog kom ua tiav lub zog zoo thiab kev sib txhuam. Cov roj hmab hluavtaws muaj qee qhov tsis zoo, tab sis cov khoom siv rau npauj npaim valve sealing uas muaj qis coefficient tau nyob ib puag ncig lawv. Txhawm rau txhim kho kev ua haujlwm ntawm npauj npaim li qub, cov khoom siv polymer siab molecular, xws li polytetrafluoroethylene, thiab lawv cov ntaub ntawv hloov pauv tau siv dav. Nws tau tam sim no tau hloov kho dua tshiab, thiab npauj npaim valve tau tsim nrog qhov kub thiab txias ntau dua, kev ua haujlwm ruaj khov, thiab lub neej ntev dua.

Hlau-sealed npauj npaim li qub tau nce siab heev txhawm rau ua kom tau raws li qhov xav tau ntawm cov ntawv thov kev lag luam xws li kub thiab qis, muaj zog yaig, thiab lub neej ntev. Hlau-sealed npauj npaim li qub tau siv dav hauv kev lag luam xws li kub thiab qis, muaj zog yaig, thiab lub neej ntev ua tsaug rau kev siv cov kub kub, tsis kub tsis kam, muaj zog corrosion kuj, muaj zog yaig, thiab lub zog siab. cov ntaub ntawv alloy. Txhawm rau txhawm rau txhim kho npauj npaim valve thev naus laus zis, txoj kab dav dav (9-750mm), siab siab (42.0MPa), thiab qhov kub ntawm qhov dav (-196-606 ° C) npauj npaim li qub thawj zaug.

Npauj npaim valve muaj me ntsis ntws tsis kam thaum nws qhib tag nrho. Npauj npaim li qub feem ntau siv nyob rau hauv txoj kab loj-txoj cai vim tias lawv muaj peev xwm tswj tau qhov dej ntws zoo ntawm qhov qhib ntawm 15 ° thiab 70 °.

Feem ntau ntawm cov npauj npaim li qub tuaj yeem siv nrog cov xov xwm uas muaj cov khoom raug tshem tawm txij li lub phaj npauj npaim txav mus rau hauv cov lus tsa suab. Nws kuj tseem siv tau rau cov khoom siv granular thiab powdery media, nyob ntawm seb lub foob lub zog.

Npauj npaim li qub muaj txiaj ntsig zoo rau kev tswj cov dej ntws. Thaum xaiv lub npauj npaim valve, nws yog ib qho tseem ceeb kom xav txog tag nrho cov kev cuam tshuam ntawm lub siab poob ntawm lub raj xa dej nrog rau lub zog ntawm tus npauj npaim phaj kom tiv taus qhov siab ntawm lub raj xa dej nruab nrab thaum nws raug kaw vim qhov siab poob ntawm npauj npaim. valve hauv cov yeeb nkab yog qhov loj, kwv yees li peb npaug ntawm lub rooj vag valve. Kev khiav hauj lwm kub ntawm cov khoom siv lub rooj zaum elastic ntawm qhov kub thiab txias yuav tsum tau coj mus rau hauv tus account.

Npauj npaim valve muaj cov qauv luv luv thiab qhov siab tag nrho qis. Nws qhib thiab kaw sai sai thiab muaj cov khoom tswj tau zoo. Ua qhov loj-ntev li qub yog qhov zoo tshaj plaws rau tus npauj npaim valve tus qauv tsim. Cov kauj ruam tseem ceeb tshaj plaws hauv kev xaiv lub npauj npaim valve uas yuav ua haujlwm kom zoo thiab ua tau zoo thaum siv los tswj kev khiav yog xaiv hom thiab specification.

Npauj npaim li qub feem ntau qhia rau kev siv rau hauv throttling, tswj kev tswj, thiab av nkos xov xwm qhov ntev ntawm cov qauv, qhib thiab kaw ceev, thiab tsis tshua muaj siab txiav tawm (me me siab sib txawv) xav tau. Npauj npaim li qub tuaj yeem siv nrog cov xov xwm abrasive, txo txoj kab uas hla, tsis tshua muaj suab nrov, cavitation thiab vaporization, me me ntawm huab cua to, thiab hloov ob txoj haujlwm. Kev hloov kho lub tog raj kheej thaum ua haujlwm nyob rau hauv cov xwm txheej txawv txawv, xws li thaum kaw ntom nti, hnav hnyav, tsis tshua muaj kub, thiab lwm yam.
