Thaum cov neeg muas zaub yuav triple eccentric npauj npaim li qub, lawv feem ntau xa mus rau ob hom qauv, ib qho yog hlau rau hlau rooj thiab lwm yam yog ntau txheej txheej;lawv muaj cov qauv sib txawv thiab cov nqi kuj txawv heev.Tom ntej no, cia peb tham txog qhov sib txawv ntawm tag nrho cov hlau rooj npauj npaim li qub thiab ntau txheej sealing npauj npaim li qub.
1. Cov yam ntxwv ntawm cov hlau rau hlau rooj npauj npaim li qub
Cov hlau rau hlau rooj npauj npaim li qub yog npauj npaim valve nrog cov qauv sib khi yooj yim, muaj lub cev valve, lub phaj valve, lub valve ncej thiab tag nrho cov hlau sealing nplhaib.Nws muaj cov qauv compact thiab hloov tau yooj yim qhib thiab kaw, yog li nws yog dav siv nyob rau hauv cov xwm txheej uas tsis tshua muaj siab, me me ntws, siab kub thiab me me plua plav hais.
Tom qab lub valve qhib, lub rooj zaum ntawm lub valve lub cev yog nyob ze rau lub nplhaib sealing.Thaum lub phaj valve raug kaw ncaj qha rau cov kua dej, cov khoom nruab nrab hauv cov kua dej loj dhau los yog tawv heev, uas yuav ua rau muaj kev sib txhuam ntawm lub rooj zaum valve lossis lub nplhaib sealing, ua rau muaj kev puas tsuaj rau lub rooj zaum valve lossis lub nplhaib sealing tiv thaiv kev sib khi ua tiav.Qhov no kuj yog ib qho kev tsis txaus ntawm cov hlau rau hlau lub rooj npauj npaim valve, vim tias kev hloov pauv tsis tu ncua yuav ua rau muaj kev sib txhuam ntxiv thiab yog li cuam tshuam rau lub neej kev pabcuam.
2. Cov yam ntxwv ntawm ntau txheej triple eccentric npauj npaim valve
Multi-txheej npauj npaim valve yog npauj npaim valve nrog txoj kev sib khi.Lub nplhaib sealing feem ntau yog tsim los ntawm ob lossis ntau txheej txheej, nrog ntau txheej txheej sealing hauv nruab nrab.Lub valve lub cev thiab valve phaj ntawm ntau txheej npauj npaim valve yog sib sau ua ke hauv txheej.Txhua txheej muaj cov qauv kev sib khi ywj pheej, uas tuaj yeem txo qhov kev pheej hmoo ntawm kev xau.Vim tias nws yog cov txheej txheem ntau txheej, txawm tias muaj cov khoom hauv nruab nrab thaum lub sijhawm kaw, tsuav yog tias tag nrho cov interlayers tsis puas, txawm tias tsuas yog ib txheej sab laug tsis muaj kev puas tsuaj, kev sib khi yuav tsis cuam tshuam.
Cov txheej ntau npauj npaim li qub feem ntau yog siv nyob rau hauv high-pressure thiab loj-ntws cov xwm txheej, xws li cov roj crude, natural gas, dej thiab lwm yam kev lag luam pipelines.Kev khiav hauj lwm kub ntawm -29 degrees thiab 425 degrees.Cov khoom siv WCB yog qhov kev xaiv zoo tshaj plaws.
3. Qhov sib txawv ntawm cov hlau rau hlau npauj npaim li qub thiab ntau txheej npauj npaim li qub
1) zoo sib xws ntawm ob lub npauj npaim vales
Ob leeghlau rau hlau npauj npaim valvethiab ntau txheej npauj npaim valve tuaj yeem ua tiav ib txoj kev sib khi lossis ob txoj kev sib khi ua haujlwm.Raws li cov neeg siv xav tau, ib lossis ntau txheej ntawm cov khoom seem sealing rings tuaj yeem hloov tau yooj yim hloov thaum siv tsis raug, thiab tau tsim los ua cov ntaub ntawv sib khi ob txoj hauv kev.Qhov zoo ntawm qhov kev tsim no yog tias lub rooj zaum valve thiab lub nplhaib sib khi tuaj yeem hloov tau hauv online, thiab cov khoom siv tsis tas yuav offline rau kev saib xyuas.Nyob rau tib lub sijhawm, lawv txhua tus muaj qhov zoo ntawm kev nruj thiab nruj.
2) qhov sib txawv ntawm ob lub npauj npaim vales no
Lub ntsiab sib txawv yog nyob rau hauv cov qauv thiab daim ntawv thov scenarios.
① qhov sib txawv ntawm cov qauv
Multi-layer npauj npaim valve
· Cov qauv ntawm ntau txheej npauj npaim valve yog ib pawg ntawm cov ntawv hlau thiab graphite, uas txhais tau hais tias lub nplhaib sealing feem ntau yog tsim los ntawm ob lossis ntau txheej, nrog ntau txheej txheej sealing hauv nruab nrab.Lub cev lub cev thiab lub plhaub valve ntawm ntau txheej npauj npaim valve tau sib sau ua ke hauv cov txheej, thiab txhua txheej muaj cov qauv kev sib khi ywj pheej.
· Lub sealing khub ntawm tag nrho cov-hlau ob-txoj kev sealing npauj npaim valve, uas yog, lub nplhaib sealing thiab lub rooj zaum valve, yog ua los ntawm tag nrho cov hlau forging.Lub nplhaib sealing tuaj yeem ua rau saum npoo los yog txau welded nrog ntau yam hnav-tiv taus thiab kub-resistant alloys.
Tag nrho cov hlau rooj npauj npaim valve
② Daim ntawv thov
Cov Hlau rau hlau npauj npaim valve yog tsim rau qhov tsis tshua muaj siab, ntws me me, thiab kub kub;ntau txheej npauj npaim valve muaj qhov ua tiav ntau txheej txheej txheej sealing, uas tuaj yeem txo qhov kev pheej hmoo ntawm kev xau.
4. Hlau rau hlau sealing kev ua tau zoo ntawm npauj npaim li qub thiab ntau txheej npauj npaim li qub
Raws li tus qauv API598, npauj npaim valve nrog cov hlau tawv tawv tuaj yeem muaj tus nqi xau, tab sis npauj npaim valve nrog ntau txheej sealing rings tuaj yeem ua tiav 0 sealing thiab muaj kev sib khi zoo dua.
5. Cov khoom ntawm tag nrho cov hlau sealing npauj npaim li qub thiab ntau txheej sealing npauj npaim li qub
·Tag nrho cov hlau foob: Lub rooj zaum valve feem ntau muaj Stellite, cov khoom siv lub cev yog WCB, SS304, SS316, SS2205, SS2507, thiab lub valve phaj sealing nplhaib tuaj yeem xaiv raws li cov khoom siv ntawm lub valve phaj;
·Multi-layer sealing nplhaib: Valve lub rooj khoom siv: Stellite, los yog lub cev khoom, valve phaj sealing nplhaib feem ntau siv RPTFE / PTFE + hlau, graphite + hlau;
Feem ntau, ob lub taub hau npauj npaim li qub thiab ntau theem npauj npaim li qub muaj lawv cov xwm txheej siv tau, thiab cov neeg siv tuaj yeem xaiv hom npauj npaim valve tsim nyog raws li qhov xwm txheej tiag tiag.Thaum xaiv ib lub npauj npaim valve, qhov tsis xws li kua siab, qhov kub thiab txias, tus nqi ntws thiab qhov nruab nrab yuav tsum raug txiav txim siab txhawm rau xaiv hom npauj npaim valve uas tsim nyog thiab ua kom lub cev ua haujlwm ntawm lub valve.
Yog tias qhov kub thiab txias tshwj xeeb thiab tsis muaj cov khoom loj, koj tuaj yeem xaiv ib qho tag nrho-hlau nyuaj-sealed npauj npaim valve.
Yog hais tias qhov kub thiab txias tsis yog qhov tshwj xeeb thiab qhov nruab nrab muaj cov khoom, xaiv tus nqi qis dua ntau txheej sealing npauj npaim valve.
