Yuav ua li cas xaiv ib qho kos duab valve puas yog?

Hauv ntau cov kua dej muaj roj, kos cov kua yog cov khoom tseem ceeb los tiv thaiv lub nraub qaum thiab tso dej, petrochemical, metallurgy thiab lwm yam kev lag luam. Txawm hais tias lub check valve zoo li yooj yim nyob rau hauv cov qauv, hauv kev xaiv tiag tiag, yog qhov yooj yim rau kev ua haujlwm tsis ua haujlwm lossis txawm tias lub cev puas tsuaj.

Rau cov neeg ua hauj lwm muaj peev xwm nkag siab cov neeg ua haujlwm, muaj tseeb kev nkag siab tus ua haujlwm ntawm lub sijhawm, tab sis kuj tau txo qis cov nqi txij nkawm tom ntej. Cov hauv qab no yuav piav qhia txog yuav ua li cas thiaj li xaiv tau ib lub ntsuas ntsuas tsim nyog los ntawm ntau yam.

1. Qhia meej cov ntaub ntawv thov

Thawj kauj ruam ntawm xaiv aKos Valveyog kom nkag siab txog cov theem pib ntawm nruab nrab. Xws li:

Hom Dej Dej (Cov Dej huv, Roj, Chav, Ua Kua Huv, thiab lwm yam)

Nruab nrab kub (tsawg kub, nruab nrab kub lossis siab kub)

Ua haujlwm siab (txawm tias nws yog lub zog siab)

Seb nws muaj cov khoom seem (xws li cov dej phwj tuaj, av nkos)

Kev ua haujlwm sib txawv ntawm cov neeg mob sib txawv muaj cov sib txawv rau cov qauv thiab cov ntaub ntawv ntawm lub cim kos. Piv txwv li, hauv kev kub siab thiab kev kub siab, roj hmab ntim yuav tsum zam, thiab siv cov cim hlau kos duab yuav tsum tau muab ua ntej.

2.Choose cov qauv tsim nyog qauv

Saib xyuas li qubtuaj yeem faib ua cov hauv qab no raws li lawv cov qauv:

Nqa Kos Valve: Tsim nyog rau installation nyob rau hauv kab rov tav kav, haum rau qee zaus nrog kev kub siab thiab nquag qhib thiab kaw. Tus qauv yog kev cog lus, tab sis kev teeb tsa kev teeb tsa yog nruj.

Viav vias Kos Valve: Loj qhib rhiab, me me siab poob, haum rau nruab nrab ntawm txoj kab uas hla kev.

Npauj npaim kos Valve: Qhov hnyav me me, feem ntau yog siv nyob rau hauv cov kab ke nrog kev tsim tawm, xws li dej tso kav kav dej.

Pob kos valve: Haum rau cov kav dej muaj cov khoom siv lossis cov xov xwm khov, uas tuaj yeem tiv thaiv kev thaiv.

Txheeb xyuas valve tso cov teeb: Tsim tshwj xeeb rau cov twj tso kua dej, nws tuaj yeem txo qhov kev cuam tshuam ntawm cov dej rauj ntawm lub system.

Thaum kev yuav khoom, koj yuav tsum xaiv hom nrog tus qauv tsim nyog raws cov txheej txheem siab, teeb meem nruab nrog thiab nruab nrab.

3.Pev xim rau cov ntaub ntawv thiab kev sib khi ua haujlwm

Cov ntaub ntawv tseem ceeb ntawm cov khoom ntsuas feem ntau suav nrog cov hlau pov tseg, hlau, thiab lwm yam.

Cov dej ua haujlwm feem ntau siv cov hlau cam khwb lossis tooj daj

Corrosive kua muaj peev xwm siv stainless hlau

Carbon Steel lossis Alloy Steel qauv yog pom zoo rau kev kub siab thiab kub cov xwm txheej

Tsis tas li ntawd, cov khoom ntim chaw ntawm cov tshev hluav taws xob ncaj qha cuam tshuam rau kev sib khi ua tau zoo thiab kev pabcuam lub neej. Mos cov ntsaws ruaj ruaj yog tsim nyog rau kev tshaj tawm kom huv ntawm chav tsev kub, thaum cov ntsaws ruaj ruaj rau qhov kub lossis qhov kub ntxhov

4.Cov kev teeb tsa thiab chaw nyob

Saib xyuas li qubFeem ntau muaj cov cai nruj me ntsis ntawm txoj kev teeb tsa. Kev teeb tsa tsis raug yuav ua rau lub valve kom tsis qhib thiab kaw ib txwm. Cov ntsiab lus hauv qab no yuav tsum nkag siab txog thaum yuav khoom:

Puas muaj chaw txaus los nruab lub cev valve

Puas yog cov raj xa dej tso cai tso cai rau kev xaiv ntawm ib hom tshwj xeeb (xws li txoj kev nqa khoom tsuas yog nruab kem kab rov tav)

Nws puas yooj yim rau kev soj ntsuam yav tom ntej thiab txij nkawm

Yog tias qhov chaw muaj tsawg, ntsug lossis wafer-type txheeb xyuas cov khoom siv tau tuaj yeem muab ua ntej

5. Txiav txim siab ob qho kev lag luam thiab kev ruaj ntseg hom

Txawm hais tias tus kos valve yog ib qho tivthaiv me me, ib zaug tsis ua tiav, nws yuav ua rau cov txheej txheem reflux, khoom puas tsuaj lossis txawm kaw. Yog li ntawd, thaum kev yuav khoom, koj tsis tuaj yeem saib ntawm tus nqi. Cov ntsiab lus hauv qab no yuav tsum tsom rau:

Seb cov khoom puas tau dhau qhov kev kuaj xyuas zoo

Seb tus muab khoom xa tuaj tom qab muag

Seb lub neej valve thiab txij nkawm yooj yim ntsib kev cia siab

Xaiv lub chaw tsim khoom hluav taws xob nrog cov khoom siv ruaj khov thiab kev txhawb nqa kev muaj peev xwm txo qis kev pheej hmoo ntawm cov haujlwm tom qab.

Thaum yuav cov tshuaj xyuas cov nqaij txiav, nws tseem ceeb dua los xaiv thiab yuav ib txoj cai

Kev xaiv ntawm daim tshev li qub zoo li yooj yim, tab sis nws yeej cuam tshuam ntau yam ntawm kev txiav txim siab txog kev ua haujlwm. Rau cov neeg yuav khoom, nkag siab txog nws hom qauv hom, thov kev ua yeeb yam yog thawj kauj ruam los xyuas kom cov haujlwm ruaj khov ntawm lub system. Nws raug nquahu kom sib txuas lus tag nrho nrog cov engineers thaum xaiv theem, thiab yog tias tsim nyog, hu rau cov neeg tsim khoom lossis xaiv cov lus qhia.

Peb tau tsom rau ntawm kev siv hluav taws xob kev lag luam valve tau ntau xyoo, thiab peb cov khoom lag luam npog ntau hom tshuaj xyuas cov khoom siv, txhawb kev hloov kho thiab cov kev pabcuam kev teeb tsa. Yog koj muaj lus nug nyob rau lub sijhawm cov txheej txheem xaiv, thov koj xavTiv Tauj Peb.
