Lub sealing kev ua tau zoo ntawm aib lub union pob valve x9201-t dawbhais txog lub peev xwm ntawm lub valve foob los tiv thaiv qhov nruab nrab to, thiab yog qhov tseem ceeb tshaj plaws kev ua tau zoo ntawm lub valve.Media leakage tuaj yeem ua rau cov khoom poob, ib puag ncig muaj kuab paug thiab txawm tias muaj xwm txheej.Rau flammable, explosive, lom los yog radioactive xov xwm, sealing kev ua tau zoo ntawm lub valve uas tsis tso cai rau xau yog hais txog lub peev xwm ntawm lub valve foob los tiv thaiv tawm tawm, uas yog qhov tseem ceeb tshaj plaws kev ua tau zoo Performance index ntawm lub valve.Media leakage tuaj yeem ua rau cov khoom poob, ib puag ncig muaj kuab paug thiab txawm tias muaj xwm txheej.Rau flammable, explosive, lom los yog radioactive xov xwm, tsis tso cai, yog li lub valve yuav tsum muaj kev ruaj ntseg sealing kev ua tau zoo.
Valve sealing thev naus laus zis tau dhau los ua kev loj hlob zoo txij li nws yug los txog rau tam sim no.Txog tam sim no, lub valve lub sealing tshuab yog feem ntau embodied nyob rau hauv ob yam, xws li zoo li qub sealing thiab dynamic sealing.Static sealing Static sealing yog hais txog kev tsim ib lub foob ntawm ob ntu zoo li qub.Lub ntsiab sealing txoj kev yog siv gaskets.Muaj ntau hom gaskets, cov hauv qab no feem ntau siv.
① Flat washer: lub tshuab ntxhua khaub ncaws tiaj tus ntawm ob qhov chaw ruaj khov.Feem ntau muab faib ua cov tshuab ntxhua khaub ncaws, roj hmab tiaj tus ntxhua khaub ncaws, cov tshuab ntxhua khaub ncaws hlau thiab cov tshuab ntxhua khaub ncaws sib xyaw raws li cov ntaub ntawv siv.
②O-ring: lub tshuab ntxhua khaub ncaws nrog O-ring hla ntu.Vim tias nws cov duab ntoo khaub lig yog O-zoo li tus, nws muaj qee yam ntawm nws tus kheej nruj, yog li cov nyhuv sealing zoo dua li ntawm lub tiaj tus gasket.
③ Washer: Ib lub tshuab ntxhua khaub ncaws uas qhwv ib qho khoom ntawm lwm yam khoom.Xws li gaskets feem ntau muaj elasticity zoo thiab tuaj yeem txhim kho cov nyhuv sealing.
④ Lub tshuab ntxhua khaub ncaws tshwj xeeb: lub tshuab ntxhua khaub ncaws uas tsis zoo.Xws li oval washers, pob zeb diamond washers, iav ntxhua khaub ncaws, dovetail washers, thiab lwm yam. Cov tshuab ntxhua khaub ncaws no feem ntau muaj cov nyhuv zawm ntawm tus kheej thiab feem ntau yog siv rau siab thiab nruab nrab siab li qub.
⑤ Wave washers: Wave washers.Hom gasket no feem ntau yog tsim los ntawm cov khoom siv hlau thiab cov khoom tsis yog xim hlau, thiab muaj cov yam ntxwv ntawm lub zog me me thiab cov nyhuv sealing zoo.
⑥ Roll-up ntxhua khaub ncaws: nyias hlau siv thiab siv tsis yog hlau yog sib txuas los tsim lub tshuab ntxhua khaub ncaws.Qhov no gasket muaj zoo elasticity thiab zoo sealing kev ua tau zoo.Dynamic sealing Dynamic sealing yog ib hom kev sib khi teeb meem thaum lub sij hawm txheeb ze ntawm lub valve.Nws tsis tso cai rau nruab nrab ntws los nrog kev txav ntawm lub valve qia.Txoj kev sealing tseem ceeb yog siv lub thawv ntim khoom.Muaj ob hom ntawm cov thawv ntim khoom: lub caj pas hom thiab compression txiv ntoo.Hom caj pas yog tam sim no feem ntau siv daim ntawv.Feem ntau hais lus, lub caj pas tuaj yeem muab faib ua hom sib xyaw thiab hom sib xyaw.Txawm hais tias txhua daim ntawv sib txawv, nws yeej muaj lub siab ntawm lub bolt.Compression txiv ntoo hom feem ntau yog siv rau cov li qub me me.Vim nws qhov me me, lub zog compression yog txwv.Nyob rau hauv lub thawv ntim khoom, vim hais tias cov ntim yog nyob rau hauv kev sib cuag ncaj qha nrog lub valve qia, tag nrho cov yuav tsum tau rau cov packing yog zoo sealing, tsis muaj kev sib txhuam coefficient, adaptable rau lub siab thiab kub ntawm nruab nrab, thiab corrosion kuj.Tam sim no, cov khoom siv feem ntau yog roj hmab O-puab
Ntiv nplhaib, PTFE braided packing, asbestos packing thiab yas molding packing.Txhua hom kev ntim khoom muaj nws cov xwm txheej thiab cov peev txheej, uas tuaj yeem xaiv raws li cov kev xav tau tshwj xeeb.
