Ivalvu yesango ye-cryogenic enebhonethi enwetshiwe eklanyelwe ukusebenza emazingeni okushisa afinyelela ku -196°C ngokuvamile yakhiwe ukuze imelane nokubanda okudlulele futhi igcine ukusebenza okufanele ezimweni ezinzima kangaka.Lawa ma-valve avame ukusetshenziswa ezimbonini ezifana ne-liquefied natural gas (LNG) processing, ukukhiqizwa kwegesi yezimboni, nezinye izinhlelo zokusebenza ze-cryogenic lapho amazinga okushisa aphansi kakhulu ahilelekile.Umklamo webhonethi owandisiwe uhlinzeka ngokufaka okungeziwe nokuvikela isiqu se-valve nokupakishwa, ukuwavimbela. kusuka emakhazeni noma ekubeni brittle emazingeni okushisa aphansi kangako.Ukwengeza, izinto ezisetshenziswa ekwakhiweni kwe-valve, njengama-alloys akhethekile noma amapulasitiki asezingeni eliphansi lokushisa, zikhethwa ukuze kugcinwe amandla nobuqotho ezindaweni ezihlala i-cryogenic.Ama-valve anjalo abalulekile ekulawuleni ngokuphepha ukugeleza kwamanzi namagesi e-cryogenic, futhi bahlolwa kanzima ukuze baqinisekise ukuthi bayakwazi ukumelana namazinga okushisa adlulele nezingcindezi ezihilelekile.
I-1.Isakhiwo silula kune-valve yesango, futhi kulula kakhulu ukukhiqiza nokugcina.
2.Indawo yokuvala akulula ukuyigqoka futhi iklwebhe, futhi ukusebenza kokuvala kuhle.Akukho ukuslayida okuhlobene phakathi kwediski ye-valve nendawo yokuvala ye-valve yomzimba lapho uvula futhi uvala, ngakho-ke ukuguga nokuklwebheka akukona okubucayi, ukusebenza kokuvala kuhle, nempilo yesevisi yinde.
I-3.Uma uvula futhi uvala, ukushaywa kwe-disc kuncane, ngakho-ke ukuphakama kwe-valve yokumisa kuncane kune-valve yesango, kodwa ubude besakhiwo bude kune-valve yesango.
4.I-torque yokuvula nokuvala inkulu, ukuvula nokuvala kuyakhandla, futhi isikhathi sokuvula nokuvala side.
I-5.Ukumelana noketshezi kukhulu, ngoba umzila ophakathi emzimbeni we-valve uyahlukumeza, ukumelana noketshezi kukhulu, futhi ukusetshenziswa kwamandla kukhulu.
6.Isiqondiso sokugeleza okumaphakathi Lapho ingcindezi ebizwa ngokuthi i-PN ≤ 16MPa, ngokuvamile ithatha ukugeleza okuya phambili, futhi okuphakathi kugeleza kuya phezulu kusuka phansi kwe-valve disc;lapho ingcindezi ebizwa ngokuthi i-PN ≥ 20MPa, ngokuvamile ithatha ukugeleza kwe-counter, futhi okuphakathi kugeleza phansi kusuka phezulu kwe-valve disc.Ukwandisa ukusebenza kwe-seal.Lapho isetshenziswa, i-globe valve medium ingageleza ibheke ohlangothini olulodwa kuphela, futhi isiqondiso sokugeleza asikwazi ukushintshwa.
7.I-disc ivamise ukuguguleka uma ivuliwe ngokugcwele.
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.

Njengomkhiqizi ochwepheshile wamavalvu ensimbi enziwe ngomgunyathi futhi othumela ngaphandle, sithembisa ukuhlinzeka amakhasimende ngesevisi yekhwalithi ephezulu yangemuva kokuthengisa, okuhlanganisa nalokhu okulandelayo:
1.Nikeza isiqondiso sokusetshenziswa komkhiqizo neziphakamiso zokuwulungisa.
2.Ngokwehluleka okubangelwa izinkinga zekhwalithi yomkhiqizo, sithembisa ukuhlinzeka ngosekelo lobuchwepheshe kanye nokuxazulula izinkinga ngesikhathi esifushane kakhulu.
3.Ngaphandle komonakalo odalwe ukusetshenziswa okuvamile, sinikeza ukukhanda kwamahhala kanye nezinsizakalo zokushintshwa.
4.Sithembisa ukuphendula ngokushesha ezidingweni zesevisi yamakhasimende ngesikhathi sewaranti yomkhiqizo.
5. Sinikeza ukwesekwa kwezobuchwepheshe kwesikhathi eside, ukubonisana nge-inthanethi kanye nezinsizakalo zokuqeqesha.Umgomo wethu uwukunikeza amakhasimende umuzwa wesevisi ongcono kakhulu nokwenza ulwazi lwamakhasimende lube mnandi futhi lube lula.
