Isivikeli se-spring-energized blowout se-Saint-Gobain Seals sika-OmniSeal sigunyazwe njengesigxivizo esimile embonini yezindiza zamarokhethi amavalvu okuhlola injini.
I-valve yokuhlola iyithuluzi lokulawula ukugeleza elivumela kuphela uketshezi olucindezelwe (uketshezi noma igesi) ukuthi lugeleze luye ohlangothini olulodwa. Ekusebenzeni okuvamile, i-valve yokuhlola isendaweni evaliwe lapho isigxivizo sivikelwa ngophawu olumile oluklanyelwe ukumelana nanoma yikuphi ukuqhuma. Uma umfutho we-fluid ufinyelela noma weqa ukucindezela komkhawulo olinganiselwe, i-valve iyavuleka futhi ivumele uketshezi ukuthi ludlulise lusuka ohlangothini lwengcindezi ephezulu luye ohlangothini oluphansi lwengcindezi. Ukwehla kwengcindezi ngaphansi kwe-threshold pressure kuzobangela ukuthi i-valve ibuyele endaweni yayo evaliwe. Ama-valve okuhlola nawo ajwayelekile embonini kawoyela negesi, kanye nasemaphampu, ukucubungula amakhemikhali, kanye nezicelo zokudlulisa uketshezi.
Ezimweni eziningi, onjiniyela bokuklama bazohlanganisa ama-valve okuhlola emiklamo yabo yenjini yerokhethi. Ngakho-ke, indima yezimvu zamanzi kulezi zindondo ibalulekile kuwo wonke umsebenzi wokwethulwa. I-anti-leak seal isetshenziswa ku-valve yokuhlola ukugcina uketshezi olunomfutho ophezulu ohlangothini lokucindezela okuphezulu ngenkathi ivimbela uphawu ekufutheni ngaphandle kwendlu. Endabeni yokucindezela okukhulu kanye noshintsho olusheshayo lwengcindezi endaweni evalekile, kuyinselele kakhulu ukugcina uphawu endaweni yalo. Lapho indawo yokuvala eguquguqukayo ye-hardware iphuma odebeni oluvalayo, uphawu luvame ukuphephuka lusuke endlini ngenxa yengcindezi eyinsalela ezungeze uphawu. Ngokuvamile, ama-valve okuhlola asebenzisa izigxivizo zezihlalo (amabhulokhi alula we-PTFE), kodwa ukusebenza kwalezi zimpawu akuhambisani, futhi ngokuhamba kwesikhathi, izigxivizo zezihlalo zizokhubazeka unomphela, okuholela ekuvuzeni.
Ama-Saint-Gobain Seals' okuvikela ukuqhuma ama-seals asuselwa ekwakhiweni kwayo kwe-OmniSeal 103A futhi ahlanganisa ijakhethi ye-polymer enesikhuthazi sasentwasahlobo. Igobolondo langaphandle lenziwe ngezinto eziphathelene ne-Fluoroloy, kuyilapho isiphethu senziwe ngensimbi engagqwali kanye nezinto ze-Elgiloy®. Ngokwezimo zokusebenza ze-valve yokuhlola, inqubo ekhethekile ingasetshenziswa ukushisa nokuhlanza intwasahlobo. Isithombe esingakwesokunxele sibonisa isibonelo sesivimbeli esivamile sokuvuthela esisetshenziswa ama-Saint-Gobain seal ohlelweni lwenduku yokuvala (qaphela: lesi sithombe sihlukile kunophawu lwangempela olusetshenziswa ekufakweni kwevalvu yokuhlola, eklanywe ngokwezifiso). Izigxivizo ezinhlelweni zamavalvu okuhlola zingasebenza emazingeni okushisa aphansi afika ku-575°F (302°C) futhi zingamelana nezingcindezi ezifika ku-6,000 psi (414 bar).
Inhloso yezimpawu ze-OmniSeal ezingaqhumeki zamavalvu okuhlola injini yerokhethi ukuvala igesi enomfutho negesi ewuketshezi emazingeni okushisa angaphansi -300°F (-184°C) kuya ku-122°F (50°C). Ukucindezela kophawu kusondele ku-3,000 psi (207 bar). Impahla ye-fluoroloy® sheath inokumelana okuhle kakhulu nokugqokwa, ukumelana nokuguqulwa, i-coefficient ephansi yokungqubuzana nokusebenza kwezinga lokushisa eliphansi kakhulu. I-OmniSeal® anti-leak seals yakhelwe ukwenza amakhulukhulu emijikelezo yokusebenza ngaphandle kokuvuza.
Ulayini womkhiqizo we-OmniSeal® unemiklamo ehlukahlukene, efana ne-103A, APS, Spring Ring II, 400A, RP II ne-RACO™ 1100A, kanye nemiklamo ehlukahlukene yangokwezifiso. Le miklamo ihlanganisa imikhono ehlukahlukene yokuvala impahla ye-fluorine kanye nokuhlelwa okuhlukahlukene kweziphethu. Izixazululo zokuvala uphawu zikaSaint-Gobain Seals zisetshenziswe ekuthulweni kwezimoto njengezinjini zerokhethi ze-Atlas V (ethula iMars Rover Curiosity emkhathini), amarokhethi e-Delta IV Heavy kanye namarokhethi e-Falcon 9. Izixazululo zabo zibuye zisetshenziswe kwezinye izimboni (kawoyela negesi, ezezimoto, ezesayensi yempilo, eze-elekthronikhi nezimboni), kanye nemishini yenqubo yokudaya yezimboni ehambisana nemvelo, amaphampu omjovo wamakhemikhali, esinye seziteshi zokuqala zokucindezelwa kwegesi engaphansi kolwandle kanye nabahlaziyi bamakhemikhali. ukusetshenziswa kwekilasi. .
