Hom kev sib txuas: ORFS (O-ring Face Seal)
ORFS fittings yog dab tsi?
Raws li lub npe implies, ORFS, los yog(O-ring Face Seal) fittings suav nrog O-ring ntawm lub ntsej muag ntawm qhov haum. Ua rau SAE J1453 tus qauv, ORFS kev sib txuasfeem ntau yog tsim nyob rau hauv carbon, npib tsib xee plated carbon& Stainless hlau thiabFeem ntau siv Buna-N lossis Viton, 90 Durometer O-rings uas zaum hauv ib lub groove nyob rau hauv lub ntsej muag ntawm qhov haum. Thyog lub npe hu ua ibelastomeric foob.
Lub foob raug tsim thaum lubo-ringcompresses nruab nrab ntawm covo-ringntsej muagntawm qhov haum thiab lub ntsej muag tiaj tus ntawm mating ORFS haum lossis cov raj tsim.Thaum qhov kev sib txuas yog nruj, O-ring compresses tiv thaiv lub ntsej muag tiaj tusntawm mating haum los yog raj.
Qhov tsis zoo ntawm kev siv ORFS fittings:
Qhov ntsuas kub muaj feem cuam tshuam yog txwv los ntawmo-ringfoob cov khoomua cov fittingstsis muaj txiaj ntsignyob rau hauv high kub daim ntaub ntawv.
Qhov zoo ntawm kev siv ORFS fittings:
Lawv tau yooj yim muaj thiab muab ntau qhov ntau thiab tsawg ntawm cov duab, kev sib txuas thiab cov khoom siv
Muaj peev xwm tshem tawm cov xau hauv cov tshuab hydraulic nrog kev ua haujlwm siab
Cov ntsaws ruaj ruaj elastomeric no muab cov ntaub ntawv pov thawj, poob-hauv kev hloov pauv rau SAE 37 degree flared raj fittings, cia li tshem tawm cov dej xau thaum siv kom raug.
Siv nyob rau hauv feem ntau ntawm cov ntawv thov uas muaj kev kub ntxhov uas raug flexing lossis siab surgesthiablawvkuj yog qhov nyiam kev sib txuas nyob rau hauv siab vibration systems vim hais tias cov mos O-ring foob absorbs poob siab zoo dua tej hlau-rau-hlau kaw fittings
Yuav tau yooj yim txuas mus rau ntau yam ntawm cov qib tubing los ntawm silver brazinglos yog tsim
Qhov xwm txheej ntawm ORFS fittings tiv thaiv cov teeb meem cuam tshuam nrog kev sib sau ua ke ntau dua li lawv tuaj yeem dhau torqued los ntawmntau li 200 feem pua
Lub ntsej muag tiaj tus qauv tsim ua ke nrog kev hloov pauv ntawm lubo-ring, ua rau cov fittings reusable thiab yooj yim khaws cia nyob rau hauv lub tshav pob
Muaj lwm yamfittings uas ua kev sib txuas siv ib qhoelastomeric foob. Piv txwv li; Metric fittings, ISO 9974 Kev Tswj Xyuas Kev Lag Luam,suav nrog ibelastomeric foob nyob rau hauv ib zawj recessed rau hauv lub cev haum. Tus txiv neej ORB lossis (O-ring Boss) fittings sivsibo-ringuas zaum hauv chamfer hauv mating poj niam chaw nres nkoj.Flange kev sib txuas kuj tseem siv tauo-ringnyob rau hauv ib lub tiaj sealing ntsej muag. Qhov txawv tseem ceeb yog qhov ntawdflanged sib koom ua ke yog tsim los ntawmsiv bolts los txuas covob lub flanges ua ke nrog lub gasket nyob rau hauv-nruab nrab kom muaj kev ruaj ntseg foob.Thaum, ORFS haum yog cov xov txuas.
O-ring ntsej muag foob fittings yogfeem ntauqhov zoo tshaj plaws los yog qee zaum tsuas yog kev xaiv tswv yimthiab kev saib xyuas yuav tsum tau muab coj los txheeb xyuas qhov kev sib raug zoo los tsim kom muaj kev ruaj ntseg thiab tiv thaiv lub foob.
