OmniSeal yochokera ku Saint-Gobain Seals ndiyovomerezeka kuti igwiritsidwe ntchito ngati zisindikizo zokhazikika zamainjini a rocket

Chisindikizo cha OmniSeal chotsimikizira kuphulika kwa masika cha Saint-Gobain Seals chadziwika ngati chosindikizira chokhazikika mu valavu ya injini ya rocket yamakampani akumlengalenga. Valve yowunikira ndi chipangizo chowongolera kuthamanga chomwe chimangolola madzi opanikizika (madzi kapena gasi) kuyenda mbali imodzi. Pogwira ntchito bwino, valve yowunikira imakhala pamalo otsekedwa pomwe chisindikizocho chimatetezedwa ndi zisindikizo zosasunthika zomwe zimapangidwira kuti zisawonongeke. Kuthamanga kwamadzimadzi kukafika kapena kupitirira malire ovomerezeka, valavu imatsegula ndipo imalola madzi kuti asamuke kuchokera kumbali yothamanga kupita kumalo otsika kwambiri. Kutsika kwapansi pansi pazitsulo zolowera pakhomo kudzachititsa kuti valve ibwerere kumalo ake otsekedwa. Ma valve owunika amapezekanso m'makampani amafuta ndi gasi, komanso pamapampu, pokonza mankhwala, komanso kugwiritsa ntchito madzimadzi. Nthawi zambiri, mainjiniya opanga amaphatikiza ma valavu amacheke pamapangidwe awo a injini ya rocket. Choncho, udindo wa zisindikizo m'zigwazi ndizovuta kwambiri pa ntchito yonse yoyambitsa. Chisindikizo chotetezera kuphulika chimagwiritsidwa ntchito mu valavu yowunikira kuti madzi asungunuke pamphepete mwapamwamba pamene akulepheretsa chisindikizo kuti chisapope kunja kwa nyumbayo. Pansi pa kupanikizika kwakukulu ndi kusintha kofulumira kwa kukakamiza pamwamba pa kusindikiza, kusunga chisindikizo m'nyumba yake ndizovuta kwambiri. Pomwe malo osindikizira amphamvu a hardware amasiyanitsidwa ndi milomo yosindikiza, chisindikizocho chikhoza kuthamangitsidwa kuchoka ku nyumbayo chifukwa cha kukakamizidwa kotsalira kuzungulira chisindikizocho. Kawirikawiri zisindikizo zapampando, midadada yosavuta ya PTFE, imagwiritsidwa ntchito poyang'ana ma valve, koma machitidwe a zisindikizozi ndizosagwirizana. M'kupita kwa nthawi, zisindikizo zapampando zidzasintha kosatha, zomwe zimapangitsa kuti ziwonongeke. Zisindikizo zotsimikizira kuphulika kwa Saint-Gobain Seals zimachokera ku kasinthidwe kake ka OmniSeal 103A ndipo zimakhala ndi jekete la polima lokhala ndi zopatsa mphamvu zamasika. Chovalacho chimapangidwa ndi zinthu zamtundu wa Fluoroloy, pomwe kasupe amatha kupangidwa ndi zinthu monga chitsulo chosapanga dzimbiri ndi Elgiloy®. Malingana ndi momwe ntchito ya cheki ikuyendera, kasupe amatha kutentha ndi kutsukidwa ndi njira yapadera. Chithunzi chakumanzere chikuwonetsa chitsanzo cha zisindikizo zotsutsana ndi kuphulika kwa zisindikizo za Saint-Gobain muzitsulo zosindikizira ndodo (zindikirani: chithunzichi ndi chosiyana ndi zisindikizo zomwe zimagwiritsidwa ntchito popanga ma valve enieni, omwe amapangidwa mwachizolowezi). Chongani ma valve ntchito Zosindikizira mkati zimatha kugwira ntchito kutentha pang'ono mpaka 575 ° F (302 ° C) ndipo zimatha kupirira kupanikizika mpaka 6,000 psi (414 bar). Zisindikizo zosaphulika za OmniSeal zomwe zimagwiritsidwa ntchito m'mavavu a injini ya rocket zimagwiritsidwa ntchito kusindikiza mipweya yoponderezedwa ndi yamadzimadzi pa kutentha kosachepera -300 ° F (-184 ° C) mpaka 122 ° F (50 ° C). Chisindikizocho chimatha kupirira zovuta zapafupi ndi 3,000 psi (207 bar). Fluoroloy® sheath material ili ndi kukana kwabwino kwambiri kwa abrasion, kukana mapindikidwe, kutsika kwamphamvu kwamphamvu komanso kuzizira kwambiri kutentha. OmniSeal® Blowout Prevention Seals adapangidwa kuti aziyendetsa mazana amizungulira popanda kutayikira kulikonse. Mzere wazogulitsa wa OmniSeal® umapereka mapangidwe osiyanasiyana, monga 103A, APS, Spring Ring II, 400A, RP II ndi RACO™ 1100A, komanso mapangidwe osiyanasiyana. Mapangidwe awa amaphatikiza manja osindikiza amitundu yosiyanasiyana ya fluorine alloy ndi akasupe amitundu yosiyanasiyana. Mayankho osindikizira a Saint-Gobain Seals agwiritsidwa ntchito poyambitsa magalimoto, monga injini ya roketi ya Atlas V (kutumiza Curiosity Mars rover mumlengalenga), Delta IV heavy rocket ndi Falcon 9 rocket. Mayankho awo amagwiritsidwanso ntchito m'mafakitale ena (mafuta ndi gasi, magalimoto, sayansi ya moyo, zamagetsi ndi mafakitale) ndi zipangizo zamakono zopangira utoto wa mafakitale, mapampu a jekeseni wa mankhwala, malo oyamba padziko lapansi opangira mpweya wapansi pa nyanja ndi makina osanthula mankhwala, ndi zina zotero.
