Kwenzekani lapho ama-valve ezimbonini ebhekene nezimo ezimbi kakhulu—kungaba izinga lokushisa elingaphansi kwezinga-ziro ezigalweni zegesi yemvelo ewuketshezi noma ukushisa okuhangulayo emapayipini esitimu? Impendulo ilele kubunjiniyela be-valve obukhethekile. Ukukhetha uhlobo lwevalvu olulungile lwezindawo zokushisa ezeqisayo akukhona nje ukusebenza—kumayelana nokuphepha, ukuphila isikhathi eside, nokusebenza kahle.
Kulesi sihloko, sihlola umehluko wezobuchwepheshe phakathi kwama-valve e-cryogenic nama-valve aphezulu okushisa, okugqamisa ukucatshangelwa kokuklama, ukukhethwa kwezinto ezibonakalayo, ubuchwepheshe bokubeka uphawu, kanye nendlela yokuqinisekisa ukwethembeka ngaphansi kokucindezeleka okushisayo.
Izinga Lokushisa Lidinga Idizayini Yevalve Yomumo
Amavaluvu asebenza emakhazeni amakhulu noma ekushiseni kufanele enzelwe ukumelana nezinguquko ezithile ezibonakalayo ezenzeka ezindaweni abasebenza kuzo.
Amavalvu e-Cryogenic, ngokuvamile asetshenziswa ezinhlelweni ezibandakanya amagesi aluketshezi njenge-LNG noma umoya-mpilo owuketshezi, asebenza emazingeni okushisa aphansi afinyelela ku -196°C. Emazingeni okushisa aphansi kangako, izinto ezisetshenziswayo ziba brittle, futhi nokuvuza okuncane kungabangela izingozi zokusebenza. Lawa ma-valve kufanele aklanywe ngamabhonethi anwetshiwe ukuze avale isiqu kusuka kumithombo ebandayo futhi avimbele isithwathwa noma ukubanjwa.
Ngokuphambene, ama-valve anezinga lokushisa eliphezulu akhiwe ukuze asebenze ngaphansi kokuchayeka ngokuqhubekayo ekushiseni—ngokuvamile adlule ku-400°C. Lezi zivame ukusetshenziswa ezitshalweni zikagesi, izindawo zokuhluza, kanye nezinhlelo zesitimu esinomfutho ophezulu. Lapha, inselele ilele ekwandiseni okushisayo, i-oxidation, nokugcina i-torque engaguquki namandla okuvala.
Ukukhethwa Kwezinto Ezibalulekile: Ukuqina Ngaphansi Kokweqisa
Ukukhetha impahla efanele kubalulekile kuwo womabili ama-valve e-cryogenic kanye namazinga okushisa aphezulu.
Kuma-valve e-cryogenic, izinsimbi ezingenasici kanye nama-nickel alloys avame ukusetshenziswa ngenxa yokuqina kwawo okuhle kakhulu kanye nokuzinza kwesakhiwo emazingeni okushisa aphansi. Lezi zinto zimelana nokuqhekeka futhi zigcine izakhiwo zazo zokuvala ngisho nalapho zivezwa ukupholisa ngokushesha.
Ngakolunye uhlangothi, ama-valve asezingeni eliphezulu adinga izinto ezimelana nokuguqulwa okubangwa ukushisa, njengensimbi ye-chrome-molybdenum noma i-Inconel. Lezi zinsimbi zinikeza ukugcinwa kwamandla okuhle kakhulu nokumelana nokugqwala emazingeni okushisa aphakeme, lapho ukuhamba ngebhayisikili okushisayo kungaholela ekukhathaleni nasekuvuzeni.
Ubuchwepheshe Bokutywina: Ukunemba Kubalulekile
Ukubekwa uphawu ngendlela efanele kubalulekile ekusebenzeni kwama-valve kunoma yiliphi izinga lokushisa, kodwa izindawo eziyingozi kakhulu zethula izinselele eziyingqayizivele.
Ama-valve e-Cryogenic avame ukusebenzisa izinto ezithambile ezifakwa uphawu njenge-PTFE noma ama-elastomer akhethekile ahlala eguquguquka emazingeni okushisa aphansi. Lezi zimpawu kufanele zivumelane nokufinyela futhi zinciphise izindlela ezivuzayo ngisho nalapho uketshezi oluyiqhwa ludlula kuvalvu.
Ama-valve asezingeni eliphezulu, nokho, athembele kakhulu kuzihlalo zensimbi kuya kwensimbi nezinto zokupakisha ezisekelwe ku-graphite ezimelana nokuwohloka ezindaweni ezishisayo. Umgomo uwukuvimbela ukuqhuma nokuqinisekisa ubuqotho bokuvalwa naphezu kokwanda kwezinga lokushisa nokucindezela okukhulu kwangaphakathi.
Ukuqinisekisa Ukwethembeka Kwesikhathi Eside Ezimeni Ezidlulele
Ukugcina ukuzinza nokuphepha ngaphansi kwezimo zokushisa ezeqisayo, izinqubo ezimbalwa ezibalulekile zobunjiniyela zibalulekile:
Isinxephezelo Esishisayo: Izici zedizayini ezifana namabhonethi anwetshiwe, ukupakishwa okulayishwe bukhoma, kanye nemiklamo yezihlalo eguquguqukayo isiza ukumunca ukunwetshwa noma ukufinyela futhi kunciphise ingcindezi emzimbeni wamavalvu.
Ukuhlola Okuqinile: Amavavu kufanele ahlolwe ukusebenza kwe-cryogenic noma izinga lokushisa eliphezulu, okuhlanganisa ukutholwa kokuvuza kwe-helium, ukulingisa ukuhamba ngebhayisikili elishisayo, nokuhlolwa kokuvuza kwesihlalo.
Ukufakwa Nokunakekelwa Okufanelekile: Ngisho namavalvu aklanywe kahle kakhulu angahluleka ngaphandle kokuphathwa ngendlela efanele. Abafaki kufanele balandele imihlahlandlela ye-torque, imikhuba ehamba phambili yokufaka ugesi, futhi bahlele ukuhlolwa okuvamile, ikakhulukazi kumasistimu ahamba ngamabhayisikili.
Khetha I-Smart for Hard Conditions
Kungakhathaliseki ukuthi uphethe indawo yokugcina i-cryogenic noma wengamele isikhungo samandla ashisayo, amavalvu owakhethayo athinta ngokuqondile ukuphepha nokusebenza kwesistimu. Ngokuqonda izidingo ezithile zamavalvu e-cryogenic kanye nama-valve aphezulu, ungakwazi ukufanisa kangcono izixazululo kuhlelo lwakho lokusebenza futhi unciphise ingozi yesikhathi eside.
I-Valve ye-Taikeigxile kumavalvu ahlala isikhathi eside, akhiwe ngokunemba ezindaweni ezibucayi. Xhumana nathi namuhla ukuze uhlole izixazululo zethu futhi uqinisekise ukuthi isistimu yakho isebenza ngokuthembekile—kungakhathaliseki izinga lokushisa.
