Center kab npauj npaim valve yog ib qho ntawm cov khoom tseem ceeb uas feem ntau siv rau hauv kev lag luam tswj cov kua dej. Hauv kev siv, txhawm rau ua kom muaj kev ntseeg siab thiab kev nyab xeeb ntawm lub kaw lus, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov khoom sib khi uas tsim nyog. Kab lus no yuav qhia txog kev xaiv cov khoom sib khi thiab cov khoom siv feem ntau ntawm cov kab npauj npaim valve hauv nruab nrab los txhim kho qhov kev ntseeg siab ntawm qhov system.
Kev xaiv cov khoom sib khi uas tsim nyog rau qhov chaw nruab nrab kab npauj npaim valve yuav tsum xav txog cov hauv qab no: hom nruab nrab, qhov kub thiab txias, qhov xav tau siab thiab cov khoom ua kua. Cov kev ua haujlwm sib txawv muaj cov kev xav tau sib txawv rau cov khoom sib khi, yog li cov khoom no yuav tsum tau txiav txim siab zoo thaum xaiv cov khoom.
Ua ntej tshaj plaws, hom kev tshaj tawm yog ib qho tseem ceeb ntawm kev xaiv cov khoom sib khi. Cov xov xwm sib txawv muaj cov tshuaj sib txawv, xws li kua qaub thiab alkali, corrosion thiab toxicity. Cov khoom sib khi feem ntau suav nrog roj hmab, polymers, hlau thiab ceramics. Rau corrosive media, acid thiab alkali resistant polymer cov ntaub ntawv xws li polytetrafluoroethylene (PTFE) thiab polypropylene (PP) tuaj yeem xaiv. Rau cov xov xwm kub kub, cov khoom siv hlau sealing xws li stainless hlau yog qhov kev xaiv zoo dua.
Qhov thib ob, qhov kub thiab txias kuj yog qhov tseem ceeb uas yuav tsum tau xav txog thaum xaiv cov khoom sib khi uas tsim nyog. Cov khoom sib txawv muaj qhov sib txawv ntawm qhov kub thiab txias. Piv txwv li, cov khoom siv roj hmab feem ntau yuav muaj hnub nyoog thiab tawv ntawm qhov kub thiab txias, yog li rau qhov kub thiab txias, cov ntaub ntawv kub resistant xws li graphite thiab hlau yuav tsum tau xaiv.
Cov kev xav tau siab yog lwm qhov yuav tsum tau xav txog. Nyob rau hauv cov xwm txheej siab, cov ntaub ntawv sealing yuav tsum muaj kev ua haujlwm siab thiab lub zog. Cov ntaub ntawv hlau sealing feem ntau muaj cov khoom zoo compression thiab haum rau cov tshuab siab. Nyob rau tib lub sijhawm, elasticity thiab resilience ntawm cov ntaub ntawv sealing tseem yuav cuam tshuam rau nws cov sealing kev ua tau zoo, yog li nws yog ib qho tsim nyog yuav tau xaiv cov khoom zoo elasticity thiab resilience.
Thaum kawg, cov khoom ua kua yuav tsum tau xav txog. Qee cov kua dej muaj cov viscosity siab lossis cov teeb meem granular, thiab qhov poob ntawm cov ntaub ntawv sealing ntau dua. Hauv qhov no, cov khoom siv uas tiv taus hnav thiab corrosion, xws li polyurethane thiab roj hmab sib dhos, yuav tsum tau xaiv.
Hauv cov ntsiab lus, kev xaiv cov khoom sib khi rau qhov chaw nruab nrab ntawm kab npauj npaim valve yuav tsum xav txog yam xws li hom nruab nrab, qhov kub thiab txias, qhov xav tau siab thiab cov khoom ua kua. Kev xaiv cov khoom siv sib khi zoo tuaj yeem txhim kho kev ntseeg tau thiab kev nyab xeeb ntawm lub cev thiab txuas ntxiv lub neej kev pab cuam ntawm npauj npaim valve. Thaum kawg, nws raug nquahu kom sab laj cov kws tshaj lij engineers lossis cov kws tshaj lij tshwj xeeb thaum xaiv cov khoom sib khi kom ntseeg tau tias cov ntaub ntawv xaiv tau ua tau raws li cov kev ua haujlwm tiag tiag.
