Lub ntsiab yam ntxwv thiab kev siv ntawm pob li qub

Ua ntej, cov yam ntxwv ntawm cov qauv
1.1 Spherical qauv
Qhov tseem ceeb ntawm lub pob valve yog lub pob, thiab thaum cov kua dej ntawm lub pob valve qhib tag nrho lossis kaw, lub pob tuaj yeem tig tau 90 degrees, yog li cov qauv tsim ntawm lub pob yog qhov tseem ceeb heev rau kev ua haujlwm ib txwm muaj. pob valve. Lub pob feem ntau yog ua los ntawm stainless hlau, tooj liab, titanium alloy thiab lwm yam ntaub ntawv, uas muaj cov yam ntxwv ntawm corrosion kuj, kub tsis kam, hnav tsis kam thiab lwm yam.
1.2 Sealing qauv
Lub sealing kev ua tau zoo ntawm lub pob valve yog ib qho ntawm qhov zoo ntawm lub pob valve, yog li lub foob qauv tsim ntawm lub pob valve tseem ceeb heev. Muaj ob hom kev sib khi qauv tsim: elastic foob thiab hlau foob, ntawm cov ntaub ntawv elastic yog tsim rau nruab nrab thiab tsis tshua muaj siab ua teb, nrog rau cov yam ntxwv ntawm kev sib khi zoo thiab lub teeb ua haujlwm, thaum hlau ntsaws ruaj ruaj yog tsim rau kev kub siab thiab siab. kub teb, thiab muaj qhov zoo ntawm ntau txhim khu kev qha sealing kev ua tau zoo.
1.3 Kov qauv
Tus kov qauv ntawm lub pob valve tuaj yeem muab faib ua ob hom: ib qho yog ib qho ruaj khov thiab lwm qhov yog qhov kov. Kev tuav ruaj khov feem ntau yog siv rau cov pob valve me me, uas muaj cov yam ntxwv ntawm kev ua haujlwm yooj yim thiab kev cog lus, thaum lub tes tuav yog tsim rau cov pob loj loj, uas yog hloov tau thiab yooj yim rau kev khiav lag luam.
Qhov thib ob, qhov Scope ntawm daim ntawv thov
Pob li qub muaj qhov zoo ntawm cov qauv yooj yim, kev sib khi zoo, thiab cov dej tsis muaj zog, thiab tau siv dav hauv kev tswj dej hauv ntau qhov chaw. Nws yog tsuas yog siv hauv petrochemical, tshuaj, metallurgy, hluav taws xob fais fab, papermaking, zaub mov thiab lwm yam lag luam. Tshwj xeeb tshaj yog nyob rau hauv industrial pipelines, pob li qub nyob ib tug loj feem.
Thib peb, cov ntsiab lus tseem ceeb ntawm kev saib xyuas
Kev saib xyuas txhua hnub ntawm lub pob valve yog qhov tseem ceeb heev, uas tuaj yeem txuas ntxiv kev pabcuam lub neej ntawm lub pob valve thiab txo qhov zaus ntawm kev kho thiab hloov. Rau kev txij nkawm ntawm pob li qub, cov ntsiab lus hauv qab no yuav tsum tau sau tseg:
3.1 Kev tshuaj xyuas thiab tu tsis tu ncua
Thaum lub sij hawm siv lub pob li qub, lawv muaj kev cuam tshuam rau kev yaig ntawm ntau yam khoom, yog li nws yog ib qho tsim nyog yuav tsum tsis tu ncua xyuas kev ntxuav ntawm lub pob valve thiab ntxuav nws raws sijhawm. Nyob rau tib lub sijhawm, tshawb xyuas qhov kev sib khi thiab kev ua haujlwm ntawm lub pob valve kom ntseeg tau tias kev ua haujlwm zoo ntawm lub pob valve.
3.2 Tsis tu ncua lubrication
Pob li qub yuav tsum tau lubricated tsis tu ncua thaum siv los xyuas kom meej qhov kev ua haujlwm ntawm cov stems, bearings thiab lwm yam khoom siv ntawm lub pob li qub. Cov roj lubricating ntawm lub pob valve yuav tsum raug xaiv raws li kev siv ib puag ncig thiab kev xav tau ntawm lub pob valve.
3.3 Kev tiv thaiv kev cuam tshuam thiab kev puas tsuaj
Thaum siv lub pob valve, yuav tsum tau saib xyuas kom tsis txhob muaj kev cuam tshuam thiab kev puas tsuaj, thiab zam kev puas tsuaj rau lub pob valve. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los xyuas kom meej tias qhov chaw siv ntawm lub pob valve yog qhuav, ventilated thiab huv si kom tsis txhob muaj corrosion.
