Cov Haujlwm Tseem Ceeb & Cov Ntsiab Cai Xaiv ntawm Cov Li Qub

Cov li qub yog ib qho tseem ceeb ntawm cov kav dej hauv kev lag luam thiab ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tsim khoom.

ⅠLub luag haujlwm tseem ceeb ntawm lub valve

1.1 Hloov thiab txiav tawm cov xov xwm:lub qhov rooj vag, npauj npaim valve, lub pob valve tuaj yeem xaiv tau;

1.2 Tiv thaiv kom tsis txhob rov qab ntws ntawm qhov nruab nrab:lub valvexaiv tau;

1.3 Kho qhov siab thiab qhov ntws ntawm qhov nruab nrab: xaiv tau lub qhov kaw thiab lub qhov tswj;

1.4 Kev sib cais, kev sib tov lossis kev faib tawm ntawm cov xov xwm: lub qhov ntsaws,lub qhov rooj vag, tswj lub valve tuaj yeem xaiv tau;

1.5 Tiv thaiv kom lub siab nruab nrab tsis pub dhau qhov nqi teev tseg kom ntseeg tau tias kev ua haujlwm zoo ntawm cov kav dej lossis cov khoom siv: lub valve kev nyab xeeb tuaj yeem xaiv tau.

Kev xaiv cov li qub feem ntau yog los ntawm qhov kev xav ntawm kev ua haujlwm tsis muaj teeb meem thiab kev lag luam.

ⅡKev ua haujlwm ntawm lub valve

Muaj ntau yam tseem ceeb uas cuam tshuam, thiab ntawm no yog kev sib tham ntxaws ntxaws txog lawv:

2.1 Qhov xwm txheej ntawm cov kua dej xa mus

Hom Kua: Seb cov kua yog kua, roj, lossis pa dej cuam tshuam ncaj qha rau kev xaiv lub valve. Piv txwv li, cov kua yuav xav tau lub valve kaw, thaum cov roj yuav tsim nyog dua rau cov pob valve. Kev xeb: Cov kua xeb xav tau cov khoom siv tiv taus xeb xws li hlau tsis xeb lossis cov hlau sib xyaw tshwj xeeb. Viscosity: Cov kua viscosity siab yuav xav tau cov kab uas hla loj dua lossis cov valve tsim tshwj xeeb los txo qhov txhaws. Cov ntsiab lus ntawm cov khoom me me: Cov kua uas muaj cov khoom khov kho yuav xav tau cov khoom siv tiv taus hnav lossis cov valve tsim tshwj xeeb, xws li cov valve pinch.

2.2 Lub luag haujlwm ntawm lub valve

Kev tswj hwm kev hloov pauv: Rau cov sijhawm uas tsuas yog xav tau kev ua haujlwm hloov pauv xwb, lub pob valve lossislub qhov rooj vagyog cov kev xaiv uas nquag muaj.

Kev Tswj Xyuas Kev Nqus Dej: Thaum xav tau kev tswj xyuas kev ntws kom meej, cov qhov dej hauv ntiaj teb lossis cov qhov dej tswj hwm zoo dua.

Kev Tiv Thaiv Kev Rov Qab Los:Tshawb xyuas cov li qubsiv los tiv thaiv cov kua dej rov qab los.

Shunt lossis Merge: Lub valve peb-txoj kev lossis ntau-txoj kev valve yog siv rau kev hloov pauv lossis kev sib koom ua ke.

2.3 Qhov loj ntawm lub valve

Qhov Loj ntawm Cov Yeeb Nkab: Qhov loj ntawm lub valve yuav tsum phim qhov loj ntawm cov yeeb nkab kom ntseeg tau tias cov kua dej ntws zoo. Cov kev cai ntws: Qhov loj ntawm lub valve yuav tsum ua tau raws li cov kev cai ntws ntawm lub kaw lus, thiab loj dhau lossis me dhau yuav cuam tshuam rau kev ua haujlwm zoo. Qhov Chaw Teeb Tsa: Cov kev txwv ntawm qhov chaw teeb tsa tuaj yeem cuam tshuam rau kev xaiv qhov loj ntawm lub valve.

2.4 Kev poob ntawm lub valve

Kev poob siab: Lub valve yuav tsum txo qhov kev poob siab kom tsis txhob cuam tshuam rau kev ua haujlwm ntawm lub system.

Kev tsim cov kav dej ntws: Cov qhov dej puv nkaus, xws li cov qhov dej puv nkaus, txo qhov poob ntawm kev rub.

Hom Valve: Qee cov valve, xws li cov npauj npaim valve, muaj qhov tsis kam tsawg dua thaum qhib, ua rau lawv haum rau cov xwm txheej poob qis.

2.5 Qhov kub ua haujlwm thiab kev ua haujlwm siab ntawm lub valve

Qhov kub thiab txias: Cov ntaub ntawv valve yuav tsum tau hloov kho rau qhov kub thiab txias ntawm cov kua dej, thiab cov ntaub ntawv tiv taus kub yuav tsum tau xaiv rau hauv qhov chaw kub lossis txias.

Qib Siab: Lub valve yuav tsum muaj peev xwm tiv taus qhov siab tshaj plaws ntawm lub system, thiab lub kaw lus siab yuav tsum xaiv lub valve nrog qib siab.

Kev cuam tshuam ua ke ntawm qhov kub thiab txias: Qhov kub thiab txias siab thiab qhov siab siab xav tau kev txiav txim siab tshwj xeeb ntawm lub zog ntawm cov khoom siv thiab cov khoom siv sealing.

2.6 Cov khoom siv ntawm lub valve

Kev tiv thaiv corrosion: Xaiv cov ntaub ntawv tsim nyog raws li cov kua dej corrosiveness, xws li stainless hlau, Hastelloy, thiab lwm yam.

Lub zog kho tshuab: Cov khoom siv valve yuav tsum muaj lub zog kho tshuab txaus kom tiv taus qhov siab ua haujlwm.

Kev hloov pauv kub: Cov khoom siv yuav tsum hloov kho rau qhov kub ua haujlwm, qhov chaw kub siab xav tau cov khoom siv tiv taus cua sov, thiab qhov chaw kub qis xav tau cov khoom siv tiv taus txias.

Kev Lag Luam: Raws li qhov xav tau ntawm kev ua tau zoo, xaiv cov ntaub ntawv uas muaj kev lag luam zoo dua.
