Amavalvu eglobhu e-Cryogenic anamabhonethi anwetshiwe aklanyelwe ukusebenza emazingeni okushisa afinyelela ku -196°C aklanywe ngokukhethekile ukuze asingathe izimo ezimbi kakhulu zokusetshenziswa kwe-cryogenic.Ibhonethi enwetshiwe inikeza ukufakwa okungeziwe nokuvikela isiqu se-valve nokupakishwa ukuze kuqinisekiswe ukusebenza kahle emazingeni okushisa aphansi kangako.Lawa ma-valve asetshenziswa kakhulu ezimbonini ezifana ne-LNG (igesi yemvelo ewuketshezi), ukukhiqizwa kwegesi yezimboni, nezinye izinhlelo zokubamba uketshezi lwe-cryogenic.Ukucatshangelwa okubalulekile kwamavalvu eglobhu e-cryogenic ka -196°C kuhlanganisa:Izinto: Lawa mavalvu akhiwa kusetshenziswa izinto ezikhethekile. ezingagcina ubuqotho nokusebenza kwazo ezindaweni ze-cryogenic.Izinto ezivamile zihlanganisa insimbi engagqwali, i-carbon steel, namanye ama-alloys anezakhiwo ezisezingeni eliphansi lokushisa.Ukuvalwa Nokupakishwa: Izingxenye zokuvala kanye nokupakishwa kwevalvu kufanele kuklanywe ukuze kuhlale kusebenza kahle futhi kuguquguquke emazingeni okushisa aphansi kakhulu ukuze kuvinjwe ukuvuza nokugcina kuvaleke ngci. Ukuhlola Nokuhambisana Nemithetho: Ama-valve eglowubhu e-Cryogenic wamazinga okushisa aphansi kangaka ahlolwa ngokuqinile ukuze kuqinisekiswe ukusebenza nokuhambisana nezindinganiso zemboni ze-cryogenic service. ingase iphazamise ukusebenza kwamavalvu.Lawa ma-valve ayizingxenye ezibalulekile ekuqinisekiseni ukulawulwa okuphephile nokuthembekile kokugeleza koketshezi lwe-cryogenic.
1. Ibhonethi ye-valve iklanyelwe ukwakheka kwebhonethi enwetshiwe, engahlukanisa ithonya lemidiya yokushisa ephansi ekupakisheni, ivimbele ukusebenza kwesivalo sekhava, futhi yenze i-valve ivuleke futhi ivaleke ngokuguquguqukayo;
2. i-filler yamukela i-graphite eguquguqukayo noma i-polytetrafluoroethylene isakhiwo esihlangene, esinokumelana okuhle kokushisa okuphansi;
3. i-valve yezinga lokushisa eliphansi ithatha isakhiwo sokuvula imbobo yokunciphisa umgogodla we-valve.I-Gasket ithatha isiqeshana sesikhumba sensimbi engagqwali i-polytetrafluoroethylene noma isakhiwo sokuvunguza se-graphite esiguquguqukayo;
4. lapho i-valve ivaliwe, ukuze kuvinjwe izinga lokushisa eliphansi ekamelweni le-valve ekukhuphukeni ngenxa yokushisa, okuholela ekwenyukeni kokucindezela okungavamile, isakhiwo sokunciphisa ingcindezi sinikezwa ohlangothini oluphezulu lwesango noma umzimba we-valve;
5. indawo evalekayo ye-valve edlula i-cobalt-based cemented carbide, i-tungsten carbide emazingeni okushisa aphansi incane, imelana nokugqoka, ingagcina ukusebenza kahle kokuvala.
Ngoba ukuphuma kwemithombo yemithombo ye-liquid low-temperature efana ne-ethylene, i-oxygen ewuketshezi, i-hydrogen ewuketshezi, igesi yemvelo ewuketshezi, i-petroleum ewuketshezi neminye imikhiqizo ayigcini nje ngokuvutha futhi iyaqhuma, kodwa futhi i-gasification lapho ishisa, futhi umthamo uyanda izikhathi ezingamakhulu ukufakwa kwegesi.Impahla ye-valve yokushisa ephansi ibaluleke kakhulu, futhi impahla ayifaneleki, okuzobangela ukuvuza kwangaphandle noma ukuvuza kwangaphakathi kwegobolondo nokubekwa uphawu;Izakhiwo ezibanzi zemishini, amandla kanye nensimbi yezingxenye azikwazi ukuhlangabezana nezidingo zokusetshenziswa noma ngisho nokuphuka;Okuholela ekuvuzeni okuphakathi kwegesi ewuketshezi ebangelwa ukuqhuma.Ngakho-ke, ohlelweni lokuthuthukisa, ukuklama nokuthuthukisa ama-valve aphansi okushisa, ukwelashwa kwezinto ezibonakalayo kuyindaba eyinhloko eyinhloko.
Ngesikhathi sokuvula nokuvala i-valve yeglobu yensimbi eyenziwe ngomgunyathi, ngenxa yokuthi ukungqubuzana phakathi kwe-disc kanye nendawo yokuvala yomzimba we-valve kuncane kunaleyo ye-valve yesango, ayigugi.
I-stroke yokuvula noma yokuvala ye-valve stem imfushane kakhulu, futhi inomsebenzi wokusika othembeke kakhulu, futhi ngenxa yokuthi ukuguqulwa kwembobo yesihlalo se-valve kuhambisana nokushaywa kwe-valve disc, kulungele kakhulu ukulungiswa. wezinga lokugeleza.Ngakho-ke, lolu hlobo lwe-valve lufaneleka kakhulu ukunqunywa noma ukulawulwa nokudonsa.
