Valves ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm refineries, qhov chaw uas lawv tswj, tswj, thiab tswj kev khiav ntawm ntau yam xov xwm los ntawm cov kav dej thiab cov chaw ua haujlwm. Muab qhov nyuaj ntawm cov txheej txheem refinery thiab qhov xwm txheej tsis zoo ntawm cov khoom siv, kev xaiv thiab cov khoom zoo ntawm cov li qub yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab ua haujlwm zoo.
Feem ntau siv Valves hauv Refineries:
Rooj vag Valve:
Kev ntsuas siabPN1.6, PN2.5, PN4, PN6.3
Khoom sivKhoom siv: Carbon steel, stainless hlau, alloy steel
Muaj nuj nqi: Siv los pib lossis nres cov dej ntws hauv cov kav dej. Cov rooj vag li qub yog nyiam rau cov ntawv thov uas xav tau tag nrho, tsis muaj kev cuam tshuam.
Nres Valve (Lub Ntiaj Teb Valve):
Kev ntsuas siabPN1.6, PN2.5, PN4, PN6.3
Khoom sivKhoom siv: Carbon steel, stainless hlau, alloy steel
Muaj nuj nqi: Feem ntau siv rau kev tswj cov dej ntws. Tsis zoo li lub rooj vag li qub, nres li qub tuaj yeem siv los pib, nres, thiab tswj cov dej ntws, ua rau lawv tsim nyog rau lub hom phiaj throttling.
Pob Valve:
Kev ntsuas siabQauv: PN1.6, PN2.5
Khoom siv: carbon hlau
Muaj nuj nqi: Pob li qub yog siv rau kev kaw ceev ceev. Lawv muab kev sib khi nruj nrog lub zog qis thiab feem ntau siv rau hauv cov ntawv thov kom muaj kev ntseeg siab thiab ua haujlwm ntev.
Hard-Sealed Npauj Npaim Valve:
Kev ntsuas siabNP 2.5
Khoom siv: carbon hlau
Muaj nuj nqi: Zoo tagnrho rau throttling lossis regulating ntws thiab tuaj yeem siv rau kev pabcuam hauv kev siv hluav taws xob siab thiab kub kub. Lub hard-sealed hom yog tshwj xeeb tsim los rau durability thiab lis abrasive los yog corrosive xov xwm.
Ob Txoj Kev Npauj Npaim Valve:
Kev ntsuas siabNP1.6
Khoom siv: carbon hlau
Muaj nuj nqi: Tso cai ntws hauv ob qho kev qhia thiab feem ntau yog siv rau kev siv hluav taws xob hauv cov kav dej uas qhov chaw txwv lossis qhov hnyav dua yog qhov tseem ceeb.
Kuaj Valve:
Kev ntsuas siabPN1.6, PN2.5, PN4, PN6.3
Khoom sivKhoom siv: Carbon steel, stainless hlau, alloy steel
Muaj nuj nqi: Siv los tiv thaiv kev thim rov qab hauv qhov system. Kuaj li qub cia li tso cai ntws mus rau hauv ib qho kev taw qhia thiab tiv thaiv nws los ntawm kev thim rov qab, ua kom lub cev muaj kev ncaj ncees thiab kev nyab xeeb.
Qhov tseem ceeb ntawm Valves hauv Refineries:
Kev nyab xeeb: Valves hauv refineries yog qhov tseem ceeb rau kev tswj xyuas kev nyab xeeb los ntawm kev tswj cov dej ntws ntawm cov khoom phom sij thiab cov nplaim taws. Lawv tiv thaiv kev xau, nchuav, thiab ua rau muaj kev puas tsuaj loj.
Kev Ua Haujlwm Zoo: Kev ua haujlwm zoo li qub kom ntseeg tau tias cov txheej txheem ua haujlwm tau zoo, txo qis sijhawm thiab tswj kom pom cov qib ntau lawm.
Kev tiv thaiv ib puag ncig: Valves pab tiv thaiv ib puag ncig kev sib kis los ntawm kev tswj kev tso tawm cov tshuaj phem thiab cov pa phem, yog li txo qhov kev pheej hmoo ntawm kev ua qias tuaj thiab kev puas tsuaj ib puag ncig.
Muab cov kev ua haujlwm hnyav hauv cov chaw ua kom zoo, suav nrog kev kub ntxhov, huab cua kub, thiab qhov chaw corrosive, kev xaiv cov khoom siv valve thiab kev tsim qauv yog qhov tseem ceeb rau kev ntseeg siab thiab kev nyab xeeb mus ntev.
