Cov ntsiab lus tseem ceeb ntawm kev xaiv lub valve—TWS Valve

1. Piav qhia lub hom phiaj ntawmlub valvenyob rau hauv lub tshuab los yog khoom siv

Txheeb xyuas cov xwm txheej ua haujlwm ntawm lub valve: qhov xwm txheej ntawm cov khoom siv, qhov siab ua haujlwm, qhov kub ua haujlwm thiab txoj kev tswj hwm.

2. Xaiv hom valve kom raug

Qhov kev xaiv hom valve kom raug yog qhov yuav tsum tau ua ua ntej rau tus tsim qauv kom nkag siab tag nrho cov txheej txheem tsim khoom thiab cov xwm txheej ua haujlwm. Thaum xaiv hom valve, tus tsim qauv yuav tsum xub nkag siab txog cov yam ntxwv ntawm cov qauv thiab kev ua haujlwm ntawm txhua lub valve.

3. Txheeb xyuas qhov kawg ntawm qhov txuas ntawm lub valve

Ntawm cov kev sib txuas threaded, kev sib txuas flange, thiab kev sib txuas welded kawg, ob qho thawj zaug yog cov siv ntau tshaj plaws. Cov li qub threaded feem ntau yog cov li qub nrog lub cheeb tsam nominal hauv qab 50 hli. Yog tias lub cheeb tsam loj dhau, kev teeb tsa thiab kev kaw ntawm qhov txuas yuav nyuaj heev. Cov li qub flanged yooj yim dua rau kev teeb tsa thiab disassemble, tab sis lawv hnyav dua thiab kim dua li cov li qub threaded, yog li lawv tsim nyog rau kev sib txuas ntawm cov kav dej ntawm ntau lub cheeb tsam thiab siab. Kev sib txuas welded yog qhov tsim nyog rau cov khoom hnyav thiab txhim khu kev qha dua li kev sib txuas flanged. Txawm li cas los xij, nws nyuaj rau disassemble thiab rov nruab lub li qub txuas los ntawm kev vuam, yog li nws siv tsuas yog txwv rau cov sijhawm uas nws feem ntau tuaj yeem khiav tau ntev, lossis qhov twg cov xwm txheej ntawm kev siv hnyav thiab qhov kub siab.

4. Kev xaiv cov khoom siv valve

Thaum xaiv cov khoom siv ntawm lub plhaub valve, cov khoom sab hauv thiab qhov chaw kaw, ntxiv rau kev xav txog cov khoom siv lub cev (kub, siab) thiab cov khoom siv tshuaj lom neeg (corrosiveness) ntawm cov khoom siv ua haujlwm, qhov huv ntawm cov khoom siv (nrog lossis tsis muaj cov khoom khov) kuj yuav tsum tau nkag siab. Tsis tas li ntawd, nws yog qhov tsim nyog los xa mus rau cov cai lij choj ntawm lub xeev thiab lub chaw haujlwm siv. Kev xaiv cov khoom siv valve kom raug thiab tsim nyog tuaj yeem tau txais lub neej kev pabcuam pheej yig tshaj plaws thiab kev ua tau zoo tshaj plaws ntawm lub valve. Cov txheej txheem xaiv cov khoom siv lub cev valve yog: hlau cam khwb cia-carbon hlau-stainless hlau, thiab cov txheej txheem xaiv cov khoom siv nplhaib kaw yog: roj hmab-tooj ​​liab-hlau hlau-F4.

5. Lwm yam

Tsis tas li ntawd xwb, yuav tsum txiav txim siab seb cov dej ntws npaum li cas thiab cov dej siab npaum li cas, thiab yuav tsum xaiv lub valve uas tsim nyog siv cov ntaub ntawv uas twb muaj lawm (xws licov khoom lag luam valve, cov qauv khoom siv valve, thiab lwm yam).
