OmniSeal ya Saint-Gobain seals ndiyovomerezeka kuti igwiritsidwe ntchito ngati zosindikizira zama injini za rocket

Saint-Gobain Seals' OmniSeal's OmniSeal spring-energized blowout preventer yatsimikiziridwa ngati chidindo chokhazikika pamakampani oyendetsa ndege za roketi.
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 chisindikizo chokhazikika chomwe chimapangidwira kuti chitha kuphulika kulikonse. Kuthamanga kwamadzimadzi kukafika kapena kupitirira malire ovomerezeka, valavu imatsegula ndikulola 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 cheke mumayendedwe awo a roketi. Choncho, udindo wa zisindikizo mu zikhozi ndizofunikira kwambiri pa ntchito yonse yotsegulira. Chisindikizo chotsutsa-kutuluka chimagwiritsidwa ntchito mu valavu yowunikira kuti asunge madzi othamanga kwambiri pambali yothamanga kwambiri pamene akulepheretsa chisindikizo kuti chisapope kunja kwa nyumba. Pankhani ya kupanikizika kwakukulu ndi kusinthasintha kwachangu pamtunda wosindikizira, zimakhala zovuta kwambiri kusunga chisindikizo m'nyumba yake. Pomwe mawonekedwe osindikizira amphamvu a hardware amachoka pamlomo wosindikiza, chisindikizocho chimakhala ndi chizolowezi chothamangitsidwa kuchoka ku nyumbayo chifukwa cha kukakamizidwa kotsalira kuzungulira chisindikizocho. Kawirikawiri, ma check valves amagwiritsa ntchito zisindikizo zapampando (zosavuta PTFE midadada), koma machitidwe a zisindikizozi ndi osagwirizana, ndipo pakapita nthawi, zisindikizo zapampando zimakhala zowonongeka kwamuyaya, zomwe zimapangitsa kuti ziwonongeke.
Zisindikizo zotsimikizira kuphulika kwa Saint-Gobain Seals zimachokera ku kapangidwe kake ka OmniSeal 103A ndipo zimakhala ndi jekete la polima lokhala ndi zopatsa mphamvu zamasika. Chigoba chakunja chimapangidwa ndi eni ake a Fluoroloy, pomwe kasupe amapangidwa ndi chitsulo chosapanga dzimbiri ndi Elgiloy®. Malingana ndi momwe ntchito ya valve yogwirira ntchito imagwirira ntchito, njira yapadera ingagwiritsidwe ntchito kutentha ndi kuyeretsa kasupe. Chithunzi chomwe chili kumanzere chikuwonetsa chitsanzo cha chotchinga chodziwikiratu chomwe chimagwiritsidwa ntchito ndi zisindikizo za Saint-Gobain pakugwiritsa ntchito ndodo yosindikizira (chidziwitso: chithunzichi ndi chosiyana ndi chisindikizo chenichenicho chomwe chimagwiritsidwa ntchito pamakina a valve, omwe amapangidwa mwachizolowezi). Zisindikizo muzitsulo zogwiritsira ntchito valavu zimatha kugwira ntchito pamtunda wochepa mpaka 575 ° F (302 ° C) ndipo zimatha kupirira kupanikizika mpaka 6,000 psi (414 bar).
Cholinga cha zosindikizira za OmniSeal zotsimikizira kuphulika kwa mavavu a injini ya rocket ndikumata mpweya woponderezedwa ndi mpweya wamadzimadzi pa kutentha kochepera -300 ° F (-184 ° C) mpaka 122 ° F (50 ° C). Kupanikizika kwa chisindikizo kuli pafupi ndi 3,000 psi (207 bar). Fluoroloy® sheath material ili ndi kukana kovala bwino, kukana ma deformation, coefficient yotsika komanso kutentha kwambiri. Zisindikizo za OmniSeal® anti-leak zidapangidwa kuti zizigwira ntchito mazanamazana popanda kutayikira.
Mzere wazinthu za OmniSeal® uli ndi mapangidwe osiyanasiyana, monga 103A, APS, Spring Ring II, 400A, RP II ndi RACO™ 1100A, komanso mapangidwe osiyanasiyana. Mapangidwe awa amaphatikiza manja osiyanasiyana osindikizira a fluorine komanso masinthidwe osiyanasiyana a akasupe. Mayankho osindikizira a Saint-Gobain Seals agwiritsidwa ntchito poyambitsa magalimoto monga injini za rocket za Atlas V (zoyambitsa Mars Rover Curiosity mumlengalenga), maroketi a Delta IV Heavy ndi maroketi a Falcon 9. Mayankho awo amagwiritsidwanso ntchito m'mafakitale ena (mafuta ndi gasi, magalimoto, sayansi ya moyo, zamagetsi ndi mafakitale), komanso zipangizo zamakono zopangira utoto, mapampu a jakisoni wamankhwala, amodzi mwa malo oyamba padziko lonse lapansi opangira mpweya wa subsea ndi osanthula mankhwala. kugwiritsa ntchito kalasi. .
