Npauj Npaim Valve yog dab tsi?
Npauj npaim valve yog hom valve uas tswj cov dej ntws, cov pa roj, thiab slurries hauv cov kav dej. Nws muaj ib tug disc uas tig ib ncig ntawm ib tug ncej nyob rau hauv nruab nrab ntawm lub valve lub cev. Nyob rau hauv qhov chaw kaw, lub disc thaiv cov dej ntws. Thaum lub disc tig, nws qhib los yog kaw lub valve. Npauj npaim li qub tau paub txog lawv cov qauv tsim yooj yim, tsis tshua muaj txij nkawm, thiab ua haujlwm ceev.
Thaum twg Npauj Npaim Valve Pom Zoo?
Npauj npaim valve tau pom zoo nyob rau hauv cov xwm txheej hauv qab no:
1. Daim ntawv thov dav dav
Npauj npaim li qub feem ntau yog siv rau hauv daim ntawv loj loj, qhov twg lub qhov rooj li qub los yog lub ntiaj teb li qub yuav ua tsis tau zoo vim lawv qhov loj thiab qhov hnyav. Npauj npaim li qub yog sib zog thiab ntau compact, ua rau lawv yooj yim rau nruab thiab tswj.
2. Cov ntawv thov tsis tshua muaj siab
Npauj npaim li qub tau pom zoo rau cov ntawv thov uas tsis tshua muaj siab, qhov uas tsis tas yuav tsum muaj lub foob kaw ntom nti. Lawv tsis haum rau cov ntawv thov siab, qhov twg lub rooj vag valve lossis lub ntiaj teb valve yuav tsim nyog dua.
3. Corrosive tej yam kev mob
Npauj npaim li qub yog resistant rau corrosion, ua rau lawv zoo tagnrho rau corrosive ib puag ncig. Lawv feem ntau siv nyob rau hauv cov tshuaj thiab petrochemical industries, qhov twg muaj corrosive kua ntau.
4. Bi-directional Flow
Npauj npaim li qub yog ob-directional, txhais tau tias lawv tuaj yeem tswj cov dej ntws hauv ob qho tib si. Qhov no ua rau lawv tsim nyog rau cov ntawv thov uas cov kev taw qhia ntawm kev ntws tuaj yeem hloov pauv, xws li hauv cov chaw kho dej.
5. Tsawg suab nrov yuav tsum tau
Npauj npaim li qub yog tsim los txo cov suab nrov hauv cov kav dej. Lawv zoo tagnrho rau cov ntawv thov uas yuav tsum muaj suab nrov tsawg, xws li hauv tsev kho mob lossis thaj chaw nyob.
Thaum twg Npauj Npaim Valve Tsis Pom Zoo?
Lub npauj npaim valve tsis pom zoo nyob rau hauv cov xwm txheej hauv qab no:
1. Cov ntawv thov siab
Npauj npaim li qub tsis pom zoo rau cov ntawv thov uas yuav tsum muaj kev ua haujlwm siab. Lawv tsis yog tsim los tiv thaiv kev kub ntxhov uas yuav ntsib hauv qee qhov kev siv, xws li hauv cov roj thiab cov kav dej.
2. Kev siv kub kub
Npauj npaim li qub tsis haum rau cov ntawv thov kub. Cov khoom siv hauv npauj npaim li qub tsis yog tsim los tiv thaiv qhov kub thiab txias, thiab tej zaum yuav puas los yog deformed ntawm qhov kub thiab txias.
3. Cov ntawv thov slurry
Npauj npaim li qub tsis pom zoo rau daim ntawv thov slurry, qhov twg cov ntaub ntawv abrasive tuaj yeem muaj. Lub disc thiab lub rooj zaum ntawm npauj npaim valve yuav raug puas los ntawm cov khoom abrasive, txo cov kev ua haujlwm ntawm lub valve.
4. Tight Shut-Off Requirements
Npauj npaim li qub tsis haum rau cov ntawv thov uas yuav tsum tau ua kom nruj nruj. Lawv tau tsim los muab lub foob me me, tab sis tej zaum yuav tsis tuaj yeem muab lub kaw ntom nti hauv qee daim ntawv thov.
Xaus
Hauv kev xaus, npauj npaim valve yog pom zoo rau txoj kab uas hla loj, tsis tshua muaj siab, ob-txoj kev khiav, corrosive tej yam kev mob, thiab tsis tshua muaj suab nrov yuav tsum tau. Txawm li cas los xij, lawv tsis pom zoo rau kev kub siab, kub kub, slurry, los yog kaw-tawm daim ntawv thov. Nws yog ib qho tseem ceeb uas yuav tau xaiv txoj cai valve rau daim ntawv thov tshwj xeeb kom ntseeg tau tias kev tswj tau zoo thiab muaj txiaj ntsig zoo.
