Ob qho tib si thiab ib leeg Ferrule fittings yog siv los koom ua ke ntev ntawm txoj kev uas tsis sib xws thaum lub raj lossis haum, siv tau zoo ntawm cov khoom lag luam.
Qhov sib txawv thawj ntawm ob hom fittings yog tias ob chav ferrule fittings muaj ob ferrules - ib sab hauv qab ferrule. Los ntawm kev sib piv, ib qho ferrules tsuas yog muaj ib qho ferrule.
Hauv ob chav Ferrule fittings - qee zaum hu ua twin lossis ob lub ferrule fittings - cov haujlwm ntawm ferrule tau faib thoob plaws ib nkawm ntawm ob nkawm ntawm Twinned ferrules. Ib ferrule (cov sealing ferrule) ntsaws cov haum thiab pab tuav nws hauv qhov chaw thaum lwm tus (lub xauv ferrule) tsuas yog pab tuav qhov haum. Qhov ob ferrules tau tsim los mus nruj nreem ib ncig ntawm lub raj tsis muaj kev puas tsuaj rau lub raj raj phab ntsa.
Cov fittings yog qee zaum kuj tsim nrog xov ntau ntxiv, uas yuav pab kom tusyees faib lub siab tso rau ntawm qhov haum ntawm ob ferrules.
Hauv cov theem pib ntau, ib leeg Ferrule fittings, lub qhov ntswg tsuas yog ib qho ferrule yuav ua ob qho ntawm cov haujlwm ntawd, ob leeg sib khi lub haum thiab xauv nws nyob rau hauv qhov chaw.
Ferrules nyob rau hauv tib lub ferrule fittings tej zaum yuav qee zaum yog asymmetrical, tsis zoo li cov symmetrical fittings pom nyob rau hauv ob chav Ferrule fittings. Qhov no yog vim tias nyob rau hauv ib tug compression haum nrog ib qho symmetrical ferrule, nws muaj peev xwm rau cov txiv ntoo kom hloov torque rau lub ferrule raws li nws tau nruj. Qhov no torque tuaj yeem ua rau lub ferrule kom compress asymmetrically lossis hloov sijhawm sijhawm. Ob hom kev txav tsis yog xav tau tshwj xeeb thiab tuaj yeem ua rau ntau yam teeb meem - zoo li galling ntawm ferrule, uas tuaj yeem ua rau cov dej xau mus tas li lossis cov khoom sib xyaw ua ke.
Muab ob npaug rau Ferrule fittings yog qhov uas nyiam paub tshaj plaws thiab feem ntau nrov dua nrov thoob plaws kev lag luam dua ib qho fittings. Raws li qhov tshwm sim, ob chav ferrules feem ntau pom zoo tshaj ib lub ferrule compression raj fittings, tsis hais cov kev lis haujlwm no yuav ntsib. Txawm li cas los xij, thaum ob chav Ferrule fittings muaj lawv cov txiaj ntsig, ob leeg thiab ob chav ferrule compression raj fittings tuaj yeem yog kev xaiv zoo dua li lwm cov xwm txheej.
