Kev sib khi yog txhawm rau tiv thaiv kev toastage, thiab lub hauv paus ntsiab lus ntawm valve sealing tseem yog kawm los ntawm kev tiv thaiv xau. Muaj ntau ntau yam uas cuam tshuam rau kev sib khi ua haujlwm ntawmNpauj Npaim Li Qub, mas suav nrog cov hauv qab no:
1. Sealing qauv
Nyob rau hauv cov kev hloov ntawm kub lossis sib khi yuam, tus qauv ntawm lub khub sib khi yuav hloov. Ntxiv mus, qhov kev hloov pauv no yuav cuam tshuam thiab hloov lub zog ntawm cov sib khi sib khi, yog li txo cov kev ua tau zoo ntawm lub valve sealing. Yog li ntawd, thaum xaiv lub foob, nco ntsoov xaiv ib daim foob nrog txoj kev deformation. Nyob rau tib lub sijhawm, kuj them sai sai rau lub thickness ntawm kev sib khi saum npoo. Qhov laj thawj yog qhov kev sib chwv saum npoo ntawm cov khub sib khi tsis tuaj yeem sib phim. Thaum qhov dav ntawm qhov kev tiv tauj saum npoo ntawm kev sib tw nto nce, lub zog uas yuav tsum tau sib khi yog nce.
2. Qhov kev siab tshwj xeeb ntawm kev sib khi saum npoo
Qhov tshwj xeeb siab ntawm kev sib khi saum npoo cuam tshuam rau kev sib khi ua tau zoo ntawmTus Npauj Npaim ValveThiab kev pabcuam lub neej ntawm lub valve. Yog li ntawd, qhov tshwj xeeb siab ntawm kev sib khi saum npoo kuj tseem yog qhov tseem ceeb heev. Raws li tib qho kev mob, loj heev rau kev ua kom muaj kev puas tsuaj valve, tab sis kev ua kom muaj zog me me yuav ua rau lub zog valve. Yog li ntawd, peb yuav tsum tau txiav txim siab tag nrho cov kev tsim nyog ntawm qhov tshwj xeeb thaum tsim.
3. Lub zog ntawm lub cev ntawm nruab nrab
Lub cev lub cev ntawm lub nruab nrab kuj cuam tshuam rau kev sib khi ua tau ntawmTus Npauj Npaim ValveCov. Cov yam ntxwv rau lub cev no suav nrog qhov kub thiab txias, viscosity, thiab hydrophilicity ntawm saum npoo, ntawm lwm yam. Qhov kub hloov tsis tsuas yog cuam tshuam cov slackness ntawm txoj kev sib khi thiab qhov hloov ntawm qhov loj me, tab sis kuj muaj kev sib raug zoo ntawm cov roj. Roj viscosity nce los yog txo qis nrog kev nce qib lossis tsawg dua. Yog li ntawd, txhawm rau txo cov cawv ntawm qhov kub ntawm lub valve, peb yuav tsum tsim nws li lub valve nrog lub rooj loj me xws li yog ib lub rooj loj loj. Viscosity muaj feem xyuam rau cov permeability ntawm cov kua. Thaum nyob rau hauv tib qho kev mob, ntau dua cov viscosity, tsawg dua cov peev xwm nkag mus ntawm cov kua dej. Lub hydrophilicity ntawm lub npoo txhais tau tias thaum muaj zaj duab xis ntawm cov hlau saum npoo, zaj duab xis yuav tsum tau muab tshem tawm. Vim tias qhov no cov roj roj ntau heev, nws yuav rhuav tshem lub hydrophilicity ntawm saum npoo, uas ua rau hauv kev thaiv cov nplaim dej raws.
4. Zoo ntawm kev sib khi khub
Qhov zoo tshaj ntawm khub sib khi tsuas txhais tau tias peb yuav tsum kuaj xyuas cov ntawv xaiv, txuam thiab kev tsim cov ntaub ntawv ntawm cov ntaub ntawv. Piv txwv li, lub valve disc fits zoo nrog lub valve lub rooj sib nraus nto, uas tuaj yeem txhim kho kev ua haujlwm sib khi.
Valve Takele yog muaj ntau yam hauv lub neej thiab ntau lawm, uas tuaj yeem ua rau muaj kev phom sij, thiab cov tshuaj lom rau kev nyab xeeb rau kev nyab xeeb rau tus kheej, kev nyab xeeb thiab kev muaj kuab paug thiab ib puag ncig ib puag ncig. Xaiv cov ntsaws ntsaws ruaj ruaj raws li cov chaw sib txawv thiab siv cov yam ntxwv.
