Qhov sib txawv ntawm mos foob thiab tawv foob ntawm valve
2022-08-17 IB
Qhov sib txawv ntawm cov foob mos thiab tawv foob ntawm lub valve Ntxiv nrog rau qhov kev tiv thaiv corrosion hauv ob sab phlu, lub foob foob dav dav hais txog lub spool lossis lub rooj zaum ntawm ib qho ntawm ob cov ntaub ntawv tsis yog xim hlau (tsuas yog PTFE, roj hmab, thiab lwm yam) kaw daim ntawv. ntawm lub valve. Lub sealing nyhuv ntawm mos foob valve yog zoo dua, tab sis nyob rau hauv lub pipeline installation, kev tu tej zaum yuav tawm ntau los yog tsawg tsis huv cov khib nyiab (xws li vuam slag, hlau filings, thiab lwm yam), lawv ntws los ntawm lub regulating valve, yooj yim mus khawb qhov muag. foob lub rooj zaum los yog spool, kom tus nqi xau nce, kev ntseeg siab ntawm lub foob tsis zoo. Yog li ntawd, qhov kev xaiv ntawm cov qauv mos mos yuav tsum xav txog qhov nruab nrab tu thiab nruj lub raj xa dej ua ntej ua haujlwm. Valve soft seal thiab hard seal sib txawv: (1) Mos foob Ntxiv nrog rau cov kev tiv thaiv corrosion hauv ob sab phlu, cov khoom muag muag dav dav hais txog lub spool lossis lub rooj zaum ntawm ib qho ntawm ob qho khoom tsis yog xim hlau (tsuas yog PTFE, roj hmab, thiab lwm yam. ) kaw daim ntawv ntawm lub valve. Lub sealing nyhuv ntawm mos foob valve yog zoo dua, tab sis nyob rau hauv lub pipeline installation, kev tu tej zaum yuav tawm ntau los yog tsawg tsis huv cov khib nyiab (xws li vuam slag, hlau filings, thiab lwm yam), lawv ntws los ntawm lub regulating valve, yooj yim mus khawb qhov muag. foob lub rooj zaum los yog spool, kom tus nqi xau nce, kev ntseeg siab ntawm lub foob tsis zoo. Yog li ntawd, qhov kev xaiv ntawm cov qauv mos mos yuav tsum xav txog qhov nruab nrab ntawm kev ntxuav thiab nruj lub raj xa dej ua ntej ua haujlwm. (2) Hard seal Hard seal thiab surfacing ntawm hnav-resistant alloy yog ib qho kev xaiv zoo dua rau kev txiav tawm li qub. Txoj kev no hauv kev xav txog kev sib khi thiab tseem xav txog kev pabcuam lub neej thiab kev ntseeg tau, txawm hais tias lub Hoobkas Performance index tsuas yog 10-6 ~ 10-8, tsis tuaj yeem ua tiav cov txiaj ntsig ntawm cov mos mos xoom xau, tab sis txaus kom ua tau raws li qhov yuav tsum tau ua kom nruj txiav, thiab nws yog ruaj khov, los ntawm kev lag luam ntawm qhov pom yog tus nqi zoo dua.
