I-OmniSeal evela ku-Saint-Gobain Seals ivunyelwe ukusetshenziswa njengezigxivizo ezimile zezinjini zamarokhethi

Uphawu lwe-OmniSeal olunamandla entwasahlobo oluvikela ukuqhuma lwe-Saint-Gobain Seals luhlonzwe njengophawu olumile kuvalvu yokuhlola injini yerokhethi embonini ye-aerospace. 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 uphawu luvikelwa khona ngezigxivizo ezimile eziklanyelwe 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 bahlanganisa ama-valve okuhlola emiklamo yabo ye-rocket injini. Ngakho-ke, indima yezimvu zamanzi kulezi zigodi ibaluleke kakhulu kuwo wonke umsebenzi wokwethulwa. Isivalo sokuvimbela ukuqhuma sisetshenziswa kuvalvu yokuhlola ukuze kugcinwe uketshezi olucindezelwe ohlangothini lokucindezela okukhulu kuyilapho kuvimbela uphawu ukuba lufafaze luphume endlini. Ngaphansi kwengcindezi ephezulu kanye nezinguquko ezisheshayo zokucindezela endaweni yokuvala, ukugcina uphawu endlini yalo kuyinselele kakhulu. Lapho indawo yokuvala eguquguqukayo ye-hardware ihlukaniswa nodebe oluvalekayo, uphawu lungashaywa lusuke endlini ngenxa yengcindezi eyinsalela ezungeze uphawu. Ngokuvamile izigxivizo zezihlalo, amabhlogo we-PTFE alula, asetshenziselwa ukuhlola amavalvu, kodwa ukusebenza kwalezi zimpawu akuhambisani. Ngokuhamba kwesikhathi, izigxivizo zezihlalo zizoshintsha unomphela, okuholela ekuvuzeni. Izigxivizo ze-Saint-Gobain Seals' ezivikela ukuqhuma zithathwe ekucushweni kwayo kwe-OmniSeal 103A futhi zihlanganisa ijakhethi ye-polymer enesikhuthazi sasentwasahlobo. Umgodla wenziwe ngezinto eziphathelene ne-Fluoroloy, kuyilapho isiphethu singenziwa ngezinto ezifana nensimbi engagqwali ne-Elgiloy®. Ngokwezimo zokusebenza ze-valve yokuhlola, intwasahlobo ingaphathwa ngokushisa futhi ihlanzwe ngenqubo ekhethekile. Isithombe esingakwesokunxele sibonisa isibonelo sezimpawu zokunqanda ukuqhunyiswa kwezigxivizo ezivamile ze-Saint-Gobain ezisetshenziswayo ze-rod seal (qaphela: lesi sithombe sihlukile kunezimpawu ezisetshenziswa kuma-valve okuhlola angempela, aklanywe ngokwezifiso). Hlola izinhlelo zokusebenza zamavalvu Ama-seal angasebenza ezingeni lokushisa eliphansi afika ku-575°F (302°C) futhi angamelana nezingcindezi ezifika ku-6,000 psi (414 bar). Izigxivizo ezivikela ukuqhuma ze-OmniSeal ezisetshenziswa kumavalvu okuhlola injini yerokhethi zisetshenziselwa ukuvala amagesi acindezelwe futhi afakwe uketshezi ezingeni lokushisa elingaphansi kuka -300°F (-184°C) kuya ku-122°F (50°C). Uphawu lungamelana nezingcindezi ezisondele ku-3,000 psi (207 bar). Impahla ye-Fluoroloy® sheath inokumelana okuhle kakhulu nokuhuzuka, ukumelana nokuguquguquka, i-coefficient ephansi ye-friction kanye nekhono lokushisa elibanda kakhulu. I-OmniSeal® Blowout Prevention Seals yakhelwe ukusebenzisa amakhulukhulu emijikelezo ngaphandle kokuvuza. Ulayini womkhiqizo we-OmniSeal® unikeza imiklamo ehlukahlukene, efana ne-103A, APS, Spring Ring II, 400A, RP II ne-RACO™ 1100A, kanye nezinhlobonhlobo zemiklamo yangokwezifiso. Le miklamo ihlanganisa imikhono yokuvala yezinto ezihlukahlukene ze-fluorine alloy kanye neziphethu zokucushwa okuhlukahlukene. Izixazululo zokuvala uphawu zikaSaint-Gobain Seals zisetshenziswe ekuthulweni kwezimoto, njengenjini yerokhethi ye-Atlas V (ukuthumela i-Curiosity Mars rover emkhathini), i-Delta IV rocket esindayo kanye nerokhethi ye-Falcon 9. Izixazululo zabo ziphinde zisetshenziswe kwezinye izimboni (kawoyela negesi, ezezimoto, ezesayensi yempilo, eze-elekthronikhi nezimboni) kanye nemishini yenqubo yokudaya yezimboni ehambisana nemvelo, amaphampu omjovo wamakhemikhali, isiteshi sokuqala somhlaba sokucindezela igesi engaphansi kolwandle kanye nabahlaziyi bamakhemikhali, njll.
