Cov Lus Qhia rau Kev Xaiv thiab Kev Hloov Chaw Valve Zoo Tshaj Plaws

Qhov tseem ceeb ntawm kev xaiv lub valve: Kev xaiv cov qauv tswj lub valve yog txiav txim siab los ntawm kev xav txog cov yam xws li cov khoom siv, kub, siab thiab qis, ntws nrawm, cov khoom siv lub cev thiab tshuaj lom neeg ntawm cov khoom siv, thiab qhov huv ntawm cov khoom siv. Qhov tseeb thiab kev xav ntawm kev xaiv cov qauv valve cuam tshuam ncaj qha rau kev ua tau zoo, kev tswj hwm, kev ruaj khov ntawm kev tswj hwm, thiab lub neej ua haujlwm.

I. Cov Txheej Txheem Txheej Txheem:

1. Nruab NrabsLub Npe.
2. Qhov nruab nrab ceev, viscosity, kub, thiab kev huv ntawm qhov nruab nrab (nrog cov khoom me me).
3. Cov Khoom Siv Physicochemical ntawm Cov Khoom Siv: Kev Ua Xeb, Kev Lom Zem, thiab pH.
4. Tus Nqi Nqus Nruab Nrab: Siab Tshaj, Ib Txwm, thiab Yam Tsawg Tshaj
5. Siab Upstream thiab Downstream ntawm lub Valve: 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 xam ntawm tus nqi Cv.

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

II. Cov kev ua haujlwm:

1. Cov txheej txheem ua haujlwm: hluav taws xob, pneumatic,elector-hydraulic, hydraulic.
2. Lub Valveskev ua haujlwm: kev tswj hwm, kev kaw, thiab kev tswj hwm ua ke&kaw-tawm.
3. Txoj kev tswj:Tus neeg thov, solenoid valve, lub valve txo qhov siab.
4. Lub sijhawm ua haujlwm xav tau.

Qhov no ntawm cov kev ntsuas feem ntau yog siv los txiav txim siab qee cov khoom siv pabcuam uas yuav tsum tau teeb tsa kom ua tau raws li qhov yuav tsum tau ua haujlwm ntawm lub valve.

III. Cov kev tiv thaiv kev tawg:

1. Kev ntsuas tiv thaiv kev tawg.
2. Qib kev tiv thaiv.

IV. Daim Ntawv Teev Cov Kev Ntsuas Ib Puag Ncig thiab Kev Hloov Pauv

1. Kub ib puag ncig.
2. Cov kev teeb tsa fais fab: cua txias, lub zog fais fab.

Cov Kev Ceev Faj rau Kev Hloov Cov Li Qub

Yuav kom paub tseeb tias hloov lub valve sib xws thiab tiv thaiv teeb meem kev teeb tsa, thov muab cov qhov ntev hauv qab no. Kev sib txawv ntawm cov chaw tsim khoom thiab cov qauv tsim tuaj yeem ua rau tsis haum lossis tsis txaus qhov chaw. NtawmTWS, peb cov kws tshaj lij yuav kho ib qho kev daws teeb meem los ntawm kev pom zoo lub valve zoo—npauj npaim valve, lub qhov rooj vag, los yoglub valve—rau koj cov kev xav tau, lav qhov ua tau zoo thiab ruaj khov.
