1. Kev sib txuas qauv
Wafer valve
Ob chav clamping qauv: ntev bolts nkag mus rau Flange Qhov ntawm ob sab ntawm lub valve lub cev kom clamp lub valve ntawm cov yeeb nkab flanges. Nws yog ib qho yooj yim rau nruab tab sis tau muaj kev ruaj khov tsis muaj zog.
Tsis muaj flange flange: tsis muaj flange ntawm ob qho kawg ntawm lub cev valve, thiab kev sib khi yog ua tiav los ntawm kev vam khom clamping ntawm lub yeeb nkab flange.
Chav Hluav Taws Xob
Flange lossis xov ntawv txuas:
Los ntawm hom siab lub qhov siab: zoo ib yam li Wafer valve, nws tau txuas los ntawm ntev bolts, tab sis lub valve lub cev muaj lub nra muaj zog dua wafer valve.
Threaded Qhov Siab Siab Lub Qhov: Lub Ntsia Rolt yog ncaj qha screed rau hauv lub xovtooj ntawm tag nrho lub cev, uas tau ruaj khov rau nruab thiab muaj zog creep resistance.
2. Cov qauv nta
Wafer valve
Compact thiab Lub Teeb: Lub Qhov Valve Lub Cev luv luv nyob rau hauv ntev (tsuas yog 1/3 ntawm Flange Valve), lub teeb nyob rau hauv qhov hnyav, thiab haum rau pipelines nrog txwv chaw.
Nyob ntawm cov raj xa hluav taws kub flange: kev sib khi ua tau zoo yog cuam tshuam los ntawm lub zog clamping, thiab cov bolts yuav plam thiab ua kom tsis txhob muaj kev haus dej ntev. Chav Hluav Taws Xob
Kev ywj pheej Flange lossis Lug Tsim: lub valve lub cev muaj tus qauv khi, thiab qee tus qauv tau sib txuas nrog Flange kev txuas, muaj zog coj tus cwj pwm muaj peev xwm.
Kev cuam tshuam zoo heev: kev cuam tshuam zoo: threation rau lub installation tuaj yeem disperse muaj kev ntxhov siab thiab txo qhov kev pheej hmoo ntawm kev deformation ntawm kev sib khi saum npoo.
3. Kev Ua Lag Luam
Wafer valve
Clamping kev quab yuam foob: lub valve lub cev yog compressed los ntawm flange compression quab yuam. Mos sealing cov ntaub ntawv (xws li EPDM, PTFE) yog nquag mus rau kev laus thiab yuav tsum tau tu ib txwm.
Muaj feem xyuam rau qhov nruab nrab thiab qis: qib siab yog pn 10- pn25, thiab cov mob siab rau cov to taub.
Chav Hluav Taws Xob
Ntau theem sib khi lus xaiv:
Mos foob: Cov fluororubber lossis graphite composite gasket yog siv, nrog qhov kub kub tsis kam ({}} degree ~ 280 degree).
Lub suab nrov: cov chaw sib khi hlau (xws li cov hlau stainless lossis tso tseg carbide) yog tsim nyog rau cov kub thiab siab dua lossis sib npaug zos / daus las. IV. Daim Ntawv Thov Kev Pab Cuam
Wafer li qub
Kev xa dej hauv nroog: Hnav tsim kom haum rau kev teeb tsa ceev ntawm cov yeeb nkab tes hauj lwm, tus nqi tsawg.
Cov xov xwm ceev ceev: xws li cov dej txias thiab cua tshuab, kom tsis txhob muaj teeb meem los ntawm kev hnav cov npoo sib khi.
Lug Li Qub
Kev kub siab muaj lub xov hluav taws xob: xws li cua sov lossis cov xov xwm corrosive hauv cov petrochemical thiab kev lag luam fais fab.
Nquag disassembly science: xov teeb tsa pab txhim kho kev saib xyuas thiab txo qhov kev pheej hmoo ntawm cov raj xa dej tsis zoo.
V. Nqe thiab Txij Nkawm
Nqe Lus Piv
Wafer li qub muaj tus nqi qis tshaj (tsis muaj cov flange uas tsis yeem), Lug li qub), Lug li qub), Lug Li Qub yog qhov thib ob, thiab Flange li qub yog kim tshaj plaws.
Txij Nkawm Cov Nqi
Wafer li qub yuav tsum tau kuaj nruj me ntsis ntawm bolts thiab kev laus ntawm cov nplhaib sib khi; Lug Li Qub tau ntau dua sib npaug ruaj khov thiab kev txij nkawm kev lag luam ntev dua
