Yintoni ivalve ye-cryogenic -cryogenic ball valve?
- Izivalo zeCryogenic zithetha ukuba ivalve iya kusetyenziswa kubushushu obuphantsi kakhulu njenge -196 ℃ izicelo ezibandayo.Ngokwemigangatho eyahlukeneyo yezinto kunye nesakhiwo soyilo lwevalvu, iivalvu ze-cryogenic ezipholileyo zahlukile njenge--40 ℃ yentsimbi ephantsi yekhabhoni, kunye ne-100 ℃ yentsimbi engenanto, kunye -196 ℃ yentsimbi engenanto.Uhlobo lwevalve ye-cryogenic lubandakanya ivalve yebhola ye-cryogenic, ivalve yesango ye-cryogenic, ivalve yeglowubhu ye-cryogenic, ivalve yokujonga i-cryogenic kunye nevalve yebhabhathane ye-cryogenic.
- Ivalve yebhola ye-cryogenic yeyona ixhaphakileyo phakathi kweevalvu zendlela yayo engathintelwanga yokuhamba, ukuxhathisa ulwelo oluncinci, ukunqunyulwa ngokukhawuleza kunye nokusebenza kakuhle kubushushu obuphantsi.
- Zeziphi iivalufa zecryogenic ezisetyenziselwa ishishini kunye nendawo?
- Iivalvu zebhola ze-ARANCryogenic ezilungiselelwe ukuthuthwa kokhuseleko ukusetyenzwa, ukugcinwa, ukuthunyelwa kunye nokuhanjiswa kwe-ethylene, i-Nitrogen yolwelo, i-Oxygen, i-LPG, i-Liquefied Natural Gas (LNG) kunye nezinye iigesi ezinobushushu obuphantsi.
- Ezi midiya azigcini nje ukutsha kwaye ziqhuma, kodwa ziphinde zifake i-gasify xa zifudumeza okanye zivutha, kwaye umthamo wazo ukhula ngokukhawuleza ngexesha le-gasification.Ukuba ivalve ehambisa olu lwelo inomngxuma wevalvu evaliweyo kwaye uyilo lwevalvu lungekho ngqiqweni, oko kuya kubangela umngxuma wevalvu ukuba ugqithise uxinzelelo, okukhokelela ekuvuzeni okuphakathi, okuphakathi kunokuba yingozi, ukutsha okanye ukuqhuma okanye kubangele ukuqhekeka kwevalvu kunye neengozi. .
- I-ARAN Cryogenic ball valve design feature
- Iivalvu zebhola ze-cryogenic zinezakhiwo zoyilo ezikhethekileyo ezidibana nokusetyenziswa kokhuseleko lwenkonzo.
- ● Iivalvu ze-cryogenic ziyilwe ngesiqu esandisiweyo kunye nephalethi yokuthontsiza amanzi kwisikhondo.
- ● Yandisa isiqu sokubala ngokwe-SHELL SPE77/200/BS6364.
- ● Ulwakhiwo Lokunceda Umzimba
- Emva kwe-gasification, umthamo we-LNG wanda ukuya kumaxesha angaphezu kwama-600, okukhokelela kwingxaki yokunyuka koxinzelelo olungaqhelekanga.Xa ivalve ivaliwe, i-LNG eqokelelana kumngxunya womzimba wevalve ifunxa ubushushu obukhulu obuvela kwindawo engqongileyo ngokukhawuleza.
- I-Gasification yenza uxinzelelo oluphezulu kumzimba wevalve, itshabalalisa ibhola kunye neendawo zokuhlala zevalve, ukuze ivalve ingasebenzi ngokuqhelekileyo.
- Ke ngoko, ivalve yendlela enye yongezwa kwisiphelo sokungena A sebhola ukuze kuqinisekiswe ibhalansi yoxinzelelo phakathi kombhobho kunye nombhobho wokungena kwaye uthintele umgodi ekunyuseni ngokungaqhelekanga uxinzelelo.
- ● Isixhobo esichasayo
- Yonke into ephakathi kwe-LNG iyatsha kwaye iyaqhushumba isixhobo esichasene ne-static siya kuhlanganiswa kumzimba wesiqu kunye nebhola.
- ● Umzimba kunye nesigqubuthelo esiphakathi seflange esitywiniweyo
- Ukuqinisekisa ukuthembeka kokutywinwa kwe-flange ephakathi phantsi kweemeko ze-cryogenic, uyilo lokutywinwa kabini luyamkelwa kwi-flange ephakathi.Isakhiwo sokutywina: I-gasket yenxeba yentsimbi 304ss + igraphite eguquguqukayo kunye nekhonkco lokutywinwa komlomo.
- ● Uyilo olukhuselekileyo lomlilo
- Uqhagamshelo lomzimba kunye nombindi weflange luthatha igasket yesilonda segraphite kunye nekhonkco lokutywinwa komlomo elitywinwe kabini elikhuselekileyo kunye nokutywinwa kwesitulo sevalve kwamkela umsesane wokutywina womlomo kunye nesakhiwo esitywiniweyo segraphite.Xa kuvela umlilo, imilebe yotywina iyanyibilika kwaye yoyisakale, kwaye i304ss igraphite yomoya kunye negraphite eguquguqukayo esebenza njengokutywina okuphambili ukuthintela ukuvuza kwangaphandle.Fig.Ukutywinwa kwe-flange ephakathi kunye noyilo oluchasene nomlilo.
- I-ARAN yenza umsebenzi ophezulu wandisa i-stem cryogenic ball valves ngonyango lwe-cryogenic kunye novavanyo kulawulo lwelebhu yendlu.Sakhe ngokukodwa ilebhu yendlu ngenxa yokufuna imveliso yevalve ye-cryogenic. Yandisa isiqu senkonzo ye-cryogenic yeevalvu zebhola iindawo eziphambili zesicelo ezifana ne-Liquified Natual Gas (LNG), i-Liquefied Petroleum Gas (LPG), izityalo ze-Ethylnee, imibhobho yerhasi yobushushu obuphantsi njl.
