I-LNG Cryogenic Ball Valve Yandisa Isiqu Ngezinga Lokushisa Eliphansi
Isici se-ARAN Cryogenic ball valve design
Ama-valve ebhola e-cryogenic anezakhiwo ezikhethekile zokuklama ezihlangana nokusetshenziswa kokuphepha kwesevisi.
● Amavalvu e-cryogenic aklanywe anesiqu esinwetshiwe kanye nephalethi yokuconsa amanzi esiqwini.
● Iphalethi lokuconsa lingavimbela umhwamuko osemoyeni ukuthi ungancibiliki bese amanzi egeleza aye endaweni yevalvu futhi abe yiqhwa, okubangele ukulimala kwamavalvu. Asetshenziswa ukuze kuqinisekiswe ukusebenza kahle kwebhokisi lokupakisha nokusebenza okuvamile kwamavalvu ebhola.Iphinde inciphise ukushisa okudluliselwa kusuka ngaphandle kuya ngaphakathi kwedivayisi.
● Nweba isibalo sesiqu ngokuya nge-SHELL SPE77/200/BS6364.Isiqu esinwetshiwe esihlobene ne-thermal conductivity of the material, indawo ye-thermal conductivity, i-coefficient yokukhipha ukushisa okungaphezulu kanye nendawo yokukhipha ukushisa.Isiqu esinwetshiwe sivumela isikhala esanele sezinto zokufakelwa futhi siqinisekisa ukuthi isiqu sipakisha umsindo ovalwe ngaphezu kuka-0℃.
● Ukupakisha okungcolile okuphansi, kuvimbela ukuvuza eduze kwesiqu futhi kuqinisekise umlilo uphephile.

Njengoba ama-valve ebhola e-cryogenic asetshenziswa ezimweni zokushisa eziphansi, i-valve kumele yomiswe ngokugcwele ngaphambi kokulethwa.Indawo yokuhlola efekthri ngokuvamile i-helium gas. Uma kukhona uketshezi emzimbeni we-valve, uketshezi lungaba sengcupheni yokuba yiqhwa ezingeni lokushisa eliphansi futhi luzokhiqiza ukucindezela ezingxenyeni zangaphakathi zevalvu.Ingcindezi izolimaza ukuvaleka kwama-valve kanye nobungozi bokulimala kwamapayipi.Kuyisizathu futhi ukuthi kungani i-valve ye-valve yebhola e-cryogenic ithathelwa indawo ukuhlolwa komfutho womoya esikhundleni sokuhlolwa kwe-hydraulic esivivinyweni sesayithi.Indawo yokuhlola indawo yokwakha ilinganiselwe futhi i-valve idinga ukomiswa ngokuqinile ngaphambi kokusetshenziswa.
Isicelo
Ama-valve ebhola e-ARAN Cryogenic aqokwe ngokusebenza okuphezulu kakhulu futhi akhiqizwa ngekhwalithi eqinile, angahlangabezana nenkonzo ejwayelekile kakhulu ye-cryogenic, futhi afake isicelo sokuhamba ngokuphepha ukuze kucutshungulwe, kugcinwe, kuhanjiswe kanye nokusatshalaliswa kwe-ethylene, i-Liquid Nitrogen, i-Oxygen, i-LPG, i-Liquefied Natural Gas ( LNG) namanye amagesi anezinga lokushisa eliphansi.
Njengamandla ahlanzekile asebenza kahle futhi agcineke, i-LNG ibonise amathuba entuthuko abanzi kuzo zonke izici zochungechunge lwezimboni.I-valve yebhola ye-Cryogenic iyi-valve edinga kakhulu ku-cryogenic liquid storage kanye nohlelo lwemishini yokuhamba.Inezinzuzo zokushintshwa okuguquguqukayo, ukubeka uphawu okuthembekile, ukuphepha nokuzinza njll.
Ukwelashwa Nokuhlolwa Kwe-Crygenic
Izingxenye ze-valve zesevisi ye-cryogenic zidinga ukwelashwa kwe-cryogenic ukuze uqiniseke ukuthi ukusebenza kwe-valve kuzofanela izinga lokushisa eliphansi.
Ukwelashwa kwe-cryogenic kuyinqubo yokubeka izingxenye ze-valve emazingeni okushisa aphansi nge-nitrogen ephakathi -196 ℃ ukuze kususwe izingcindezi ezinsalela futhi kuthuthukiswe ukumelana nokugqokwa kwezinsimbi.
