Yuav Kho Li Cas Lub Pob Valve Uas Xaim: Kho Cov Qhov Xaim Valve & Cov Teeb Meem Rooj Vag
Cov pob valve yog cov khoom tseem ceeb hauv cov txheej txheem tswj cov kua dej, tab sis qhov xau tuaj yeem ua rau kev ua haujlwm tsis zoo, muaj kev phom sij rau kev nyab xeeb, thiab pov tseg hluav taws xob kim heev. Phau ntawv qhia no qhia txog yuav kho cov pob valve uas xau li cas, daws teeb meem qhov xau ntawm lub qhov valve, thiab kho cov qhov valve tseem ceeb li cas.
Tshooj 1: Kho Qhov Xaus Pob Valve
Cov Qhov Xaus Sab Nraud (Pom Tau):
1. Qhov xau ntawm lub qhov valve:
- Ua rau:Cov khoom siv ntim khoom siv.
- Kho:Ua kom cov ntsia hlau nruj lossis hloov nrog cov khoom siv bellows / low-leakage packing.
2. Qhov Xau ntawm Lub Cev/Flange Seal:
- Ua rau:Cov foob flange puas lawm, cov kev sib txuas xoob, lossis cov casting tsis zoo.
- Kho:Hloov cov foob flange, zawm cov flange bolts, lossis hloov kho cov khoom siv ntawm lub cev valve.
Cov Qhov Xaus Sab Hauv (Zaum):
Ua rau:Kev kaw tsis tiav, cov nplaim kaw khawb, lossis lub pob/lub rooj zaum puas lawm.
Kho:Kho cov kev txwv ntawm kev kaw, ntxuav cov nplaim sealing, lossis hloov cov khoom puas lawm.
Lub Tswv Yim Zoo: Rau cov tshuab muaj zog siab, siv cov pob valve uas muaj hlau los tiv thaiv kev xau sab hauv.
Tshooj 2: Kev daws teeb meem ntawm qhov xau ntawm lub qhov valve
Cov Kauj Ruam Kho Tseem Ceeb:
1. Nias cov ntsia hlau ntawm lub pob khoom kom sib npaug (siv lub hau ntswj ntswj).
2. Hloov cov khoom ntim khoom txheem nrog:
- Cov foob pob hluav taws (cov tshuab kub siab)
- Cov khoom ntim uas muaj graphite (cov ntawv thov tshuaj lom neeg)
3. Siv roj PTFE los ua roj rau cov kav ntoo txhua peb lub hlis.
Tshooj 3: Phau Ntawv Qhia Kho Lub Rooj Vag
Cov Kev Ua Tsis Tau Zoo thiab Kev Kho:
| Qhov teeb meem | Ua rau | Kev daws teeb meem |
|---|---|---|
| Kev xau dej | Cov foob uas hnav lawm/cov rooj zaum xoob | Hloov cov gaskets, zawm cov bolts |
| Lo | Kev sib sau ua ke ntawm cov khib nyiab | Ntxuav qhov chaw, lubricate lub qia |
| Suab nrov | Cov nto sib khi tsis sib npaug | Hloov lub disk/lub rooj zaum |
| Kev Ua Haujlwm Tsis Zoo | Qia khoov | Rov kho dua lossis hloov lub qia |
Lus Cim Kev Nyab Xeeb: Ib txwm ua kom cov kav dej qis dua ua ntej kho lub qhov rooj vag.
Tshooj 4: Kev Kho Sai rau Lwm Cov Li Qub
Lub Ntiaj Teb Li Qub:
- Kho Qhov Xaus:Hloov cov foob pob ntawm lub qia + lub gasket hauv qab.
- Kev thaiv:Yaug nrog cov solvent, lubricate lub qia.
Npauj Npaim Li Qub:
- Qhov xau ntawm lub foob:Rov kho lub disc, zawm lub flange bolts kom sib npaug.
- Xaus Cov Qhov Xaus:Hloov cov gaskets uas tsis ua haujlwm + lub nplhaib sealing.
Daim Ntawv Teev Xyuas Kev Txij Nkawm Valve
1. Txhua Hli:Tshawb xyuas cov qia/ntim khoom kom paub tseeb tias puas hnav.
2. Txhua Peb Hlis:Lubricate cov stems, torque kev sib txuas.
3. Txhua xyoo:Hloov cov foob, cov qhov ntsuas siab.
4. Cov Tshuab Hydraulic:
- Siv cov roj lim xwb
- Siv cov roj nitrogen los them cov roj teeb (tsis txhob siv oxygen)
Cov Cai Tseem Ceeb ntawm Kev Teeb Tsa
- Nruab rau hauv qhov chaw kaw
-Kho cov flanges kom sib luag (tiv thaiv kev ntxhov siab ntawm lub qia)
-Ua raws li cov lus qhia ntawm lub chaw tsim khoom torque
-Cov kav dej rwb thaiv tsev: Tso cov tes tuav kab rov tav
Xaus lus
Kev paub txog kev kho cov pob valve uas xau, cov qhov valve xau, thiab kev kho cov qhov valve uas qhib lawm ua rau lub kaw lus muaj kev nyab xeeb thiab txo lub sijhawm tsis ua haujlwm. Siv cov lus qhia no los kho thiab sab laj nrog cov chaw tsim khoom kom paub txog cov kev daws teeb meem tshwj xeeb.
