Cov lus qhia rau kev xaiv Valve thiab hloov qhov kev coj ua zoo tshaj plaws

Qhov tseem ceeb ntawm kev xaiv valve: Kev xaiv ntawm cov qauv tswj valve yog txiav txim siab los ntawm kev txiav txim siab zoo xws li qhov nruab nrab siv, qhov kub thiab txias, qhov siab thiab qis qis, ntws tus nqi, lub cev thiab tshuaj lom neeg ntawm qhov nruab nrab, thiab kev huv ntawm qhov nruab nrab. Qhov tseeb thiab qhov tseeb ntawm qhov kev xaiv valve ncaj qha cuam tshuam rau kev ua haujlwm, kev tswj lub peev xwm, kev ruaj ntseg ntawm kev tswj, thiab kev pabcuam lub neej.

I. Txheej txheem Parameter:

1. Nruab nrab'sLub npe.
2. Nruab nrab ntom ntom, viscosity, kub, thiab kev huv ntawm qhov nruab nrab (nrog rau cov teeb meem).
3. Physicochemical Properties ntawm nruab nrab: Corrosiveness, Toxicity, thiab pH.
4. Nruab Nrab Flow Rates: Qhov siab tshaj plaws, ib txwm, thiab yam tsawg kawg nkaus
5. Siab Upstream thiab Downstream ntawm Valve: Qhov siab tshaj plaws, ib txwm, yam tsawg kawg nkaus.
6. Nruab nrab viscosity: qhov siab dua qhov viscosity, qhov ntau nws cuam tshuam rau kev suav ntawm tus nqi Cv.

Cov kev txwv no feem ntau yog siv los xam qhov xav tau ntawm lub valve txoj kab uas hla, ntsuas Cv tus nqi, thiab lwm yam tsis muaj qhov ntev, nrog rau kev txiav txim siab cov ntaub ntawv tsim nyog uas yuav tsum tau siv rau lub valve.

II. Functional Parameters:

1. Txoj kev ua haujlwm: hluav taws xob, pneumatic,xaiv-hydraulic, hydraulic.
2. Valve'smuaj nuj nqi: kev cai, kaw-tawm, thiab ua ke kev cai&kaw-tawm.
3. Tswj txoj kev:Tus neeg thov, solenoid valve, siab txo valve.
4. Lub sijhawm ua haujlwm xav tau.

Ib feem ntawm cov kev txwv no feem ntau yog siv los txiav txim siab qee cov cuab yeej pabcuam uas yuav tsum tau teeb tsa kom tau raws li qhov yuav tsum tau ua ntawm lub valve.

III. Explosion-proof tiv thaiv parameter:

1. Kev ntsuas tawg-pov thawj.
2. Kev tiv thaiv qib.

IV. Daim ntawv teev cov Environmental thiab Dynamic Parameters

1. Ambient kub.
2. Lub zog tsis muaj zog: huab cua muab siab, lub zog hluav taws xob siab.

Kev ceev faj rau Kev Hloov Valve

Txhawm rau kom ntseeg tau tias qhov hloov pauv tau sib xws thiab tiv thaiv teeb meem kev teeb tsa, thov muab qhov ntev hauv qab no. Kev hloov pauv ntawm cov tuam ntxhab thiab cov qauv tsim tuaj yeem ua rau tsis zoo los yog qhov chaw tsis txaus. NtawmTWS, peb cov kws tshaj lij yuav kho qhov kev daws teeb meem los ntawm kev pom zoo lub valve-npauj npaim valve, rooj vag valve, los yogkos valve- rau koj cov kev xav tau, lav kev ua haujlwm thiab kav ntev.
