Hlau Seated Pob Valve
Dab tsi yog qhov hlau zaum pob valve?
Pob valve yog ib qho ntawm feem nrov li qub rau ntau yam industries.With xws lintaRaws li cov kua dej me me, cov dej ntws tau yooj yim, qhib nrawm thiab kaw, thiab tswj tsis siv neeg yooj yim, lub pob valve tau siv dav.Tab sis lub rooj zaum lossis lub pob li qub feem ntau yog ua los ntawm PTFE thiab lwm yam khoom siv tsis yog hlau. cov ntaub ntawv, cov li qub tsis tuaj yeem siv nyob rau hauv qhov kev pabcuam ntawm qhov kub thiab txias lossis hnav tsis kam.
Yog li ntawd, lub series ntawm tshiab style practical hlau zaum pob li qubtautsim, thiabtau siv dav hauv roj av, tshuaj lom neeg kev lag luam, hluav taws xob fais fab, metallurgy, lub teeb kev lag luam thiab lwm yam
Hlau rau hlau lub rooj zaum pob valve muaj tsis tsuas yog ntau yam zoo ntawm cov khoom siv pob li qub, tab sis kuj tseem muaj cov yam ntxwv tshwj xeeb thiab zoo heev hauv cov cua sov, tshwj xeeb tshaj yog thaum cov foob tsis tuaj yeem siv, xws li hauv cov kav dej xa khoom nruab nrab nrog kev sib txhuam plua plav, slurry , thiab khoom txawv teb chaws teeb meem sib tov.
Cov yam ntxwv tseem ceeb ntawm cov hlau zaum pob valve?
1.Advanced Pob thiab Rooj Hardening Technology
Lub sealing yog effected hlau rau pluas noj ntawm lub pob thiab hlau lub rooj zaum ntawm lub pob li qub.Raws li cov kev pabcuam sib txawv thiab cov kev xav tau ntawm cov neeg siv, ntau yam khoom siv pob thiab lub rooj tawv tawv tuaj yeem siv tau, suav nrog HVOF txheej, npib tsib xee-puag alloy tshuaj tsuag vuam, siab npib tsib xee alloy tshuaj tsuag vuam, cobalt rooj plaub nyuaj alloy tshuaj tsuag vuam, thiab lwm yam. Feem ntau lub pob thiab lub rooj saum npoo hardness tuaj yeem ncav cuag HRC55-60 nrog tus nqi siab tshaj plaws ntawm HRC70.and feem ntau, qhov kub tsis kam ntawm lub ntsej muag sealing tuaj yeem yog 540 ° C. , nrog tus nqi siab tshaj plaws ntawm 980 ° C.Cov khoom siv lub ntsej muag sealing kuj zoo hnav resistant thiab cuam tshuam kev ua yeeb yam.
2. Yooj yim qhib thiab kaw valve
Nyob rau hauv qhov kev pabcuam ntawm qhov kub thiab txias, lub pob thiab lub rooj zaum yuav nthuav dav heev vim tias thermal expansion, thiab lub zog yuav nce thiab lub valve tsis tuaj yeem qhib, lub pob valve txais lub disc caij nplooj ntoos hlav lossis caij nplooj ntoos hlav loaded sealing qauv kom thermal expansion ntawm qhov chaw. nyob rau hauv qhov kub thiab txias yuav absorbed los ntawm lub disc caij nplooj ntoos hlav los yog caij nplooj ntoos hlav.Thiab nws tau ua kom ntseeg tau tias lub valve yuav hloov tau yooj yim qhib thiab kaw nyob rau hauv qhov kub thiab txias yam tsis tau nthuav dav ntau dhau.
3. Fireproof Structure Design
Nyob rau hauv cov hlau rau hlau qauv rau lub valve, lub gasket yog stainless hlau + saj zawg zog graphite thiab cov packing yog hloov tau yooj yim graphite.Yog li ntawd, kev ruaj ntseg sealing ntawm lub valve tuaj yeem ua kom ntseeg tau txawm tias muaj hluav taws kub.
4. Ob chav thaiv thiab ntshav (hlau zaum Trunnion Pob Valve)
Cov hlau zaum trunnion pob valve feem ntau yog siv lub sealing qauv ua ntej lub pob.Thaum lub valve raug kaw thiab qhov nruab nrab kab noj hniav yog emptied lub paug valve, lub upstream thiab downstream rooj yuav ntawm nws tus kheej thaiv cov dej ntawm lub inlet thiab qhov hluav taws xob kom paub txog ob chav thaiv muaj nuj nqi.
Cov hlau zaum ntab pob valve feem ntau lees txais cov qauv kev sib khi tom qab lub pob.Qhov kev taw qhia ntws yuav raug cim rau ntawm lub cev rau lub pob valve unidirectional sealing.Yog tias teev los ntawm cov neeg siv kawg, kev sib khi bidirectional tuaj yeem cuam tshuam.
5. Txhim khu kev sealing kev ua tau zoo
Qhov tshwj xeeb pob sib tsoo tshuab tau txais kev pom zoo, los ntawm kev sib hloov ntawm lub pob thiab kev sib tsoo ntawm qhov chaw sib txawv.lub pob saum npoo yuav ua tiav siab roundness thiab fineness.Qhov tsis tshua muaj siab sealing ntawm lub rooj zaum valve yog paub los ntawm lub caij nplooj ntoos hlav pre-tightened. piston nyhuv ntawm lub rooj zaum valve yog tsim tsim nyog, uas paub txog kev kub siab sealing los ntawm cov kua nws tus kheej, Lub nruj ntawm cov hlau zaum pob li qub raws li qhov yuav tsum tau ua ntawm qib IV ntawm ANSI B16.104.
