Dab tsi yog wafer npauj npaim valve?
Npauj Npaim Valveyog ib hom npauj npaim valve yam tsis muaj flanges ntawm nws lub cev. Nws yog ncaj qha clamped ntawm ob lub yeeb nkab flanges siv bolts, tso siab rau sealing gaskets ntawm ob qho kawg ntawm lub valve lub cev kom ua tiav lub foob. Los ntawm kev tig lub disc (nyob rau hauv ib tug 0-90℃ntau yam), nws enables lub txiav tawm, txuas, los yog khiav kev cai ntawm pipeline media.
Nws cov txiaj ntsig tseem ceeb nyob hauv"compact wafer installation + nqi-kev ua tau zoo ntawm npauj npaim li qub":
Qhov tsis muaj lub cev flanges ua rau me me, sib zog tsim (40% -60% sib dua li flanged npauj npaim li qub ntawm tib qhov loj) thiab qhov chaw qis dua.
Tus nqi tseem ceeb rau cov kab loj loj (DN300 thiab siab dua).
Tsis tshua muaj dej tsis kam (flow resistance coefficient Tsawg dua lossis sib npaug li 0.2), ua rau nws haum rau nruab nrab / qis-siab, qhov chaw- txwv cov kav dej.
Siv dav hauv kev kho dej, kev tsim vaj tsev hauv nroog, HVAC, thiab kev lag luam teeb.
Ua raws li cov qauv xws liGB/T 12238thiabAPI 609 CovUa kom lub installation sealing kev ntseeg tau thiab ruaj khov tshaj tawm tswj.
Core Structure thiab Txoj Cai Ua Haujlwm
Lub wafer npauj npaim valve yog ncaj qha clamped ntawm ob lub yeeb nkab flanges siv ob - taub hau bolts, tshem tawm qhov xav tau ntxiv flange connectors. Qhov kev tsim no ua kom cov qauv compact nrog tsawg kawg qhov chaw yuav tsum tau ua. Nws cov khoom tseem ceeb muaj xws li:
Npauj Npaim Phaj (Disc): Lub voj voog kaw uas tig 0℃-90℃nyob ib ncig ntawm lub valve kom tswj kev ntws. Thaum qhib tag nrho, tsuas yog lub disc lub thickness ua rau ntws tsis kam, ua rau lub siab poob qis.
Lub cev valve: Ua los ntawm cov ntaub ntawv xws li cam khwb cia hlau, ductile hlau, stainless hlau, los yog hlau alloy kom haum raws li cov xov xwm sib txawv thiab siab xav tau.
Sealing Structure:
Soft Seal: Siv cov ntaub ntawv elastic zoo li roj hmab (NBR, EPDM) lossis PTFE, muab kev sib khi zoo heev tab sis txwv tsis pub muaj qhov kub thiab txias (tsawg dua lossis sib npaug li 120 degree). Haum rau dej, gases, thiab lwm yam uas tsis yog -corrosive media.
Hlau Hard Seal: Features stainless hlau los yog cobalt -raws li alloy welded sealing nto, withstanding kub (tsawg dua los yog sib npaug rau 650 degree) thiab pressures (tsawg dua los yog sib npaug rau 425℃chav). Nws muaj lub neej ua haujlwm ntev thiab zoo tagnrho rau cov mob hnyav hauv tshuaj lom neeg, metallurgical, thiab lwm yam kev thov.
Txoj Kev Ua Haujlwm: Txhawb nqa phau ntawv (lub tes tuav lossis lub gearbox), hluav taws xob, pneumatic, lossis hydraulic ua haujlwm kom ua tau raws li kev tswj hwm kev xav tau.
