Shaabada ka-hortagga qaraxa ee OmniSeal ee Saint-Gobain Seals ayaa loo aqoonsaday inay tahay shaabad taagan oo ku jirta waalka hubinta mishiinka gantaallada ee warshadaha hawada sare.
Qalabka hubinta waa aaladda kontoroolka socodka kaas oo u oggolaanaya dareeraha la cadaadiyo (dareere ama gaas) oo keliya inuu u socdo hal dhinac. Hawlgalka caadiga ah, waalka hubintu wuxuu ku yaalaa meel xiran halkaasoo shaabadda lagu xirayo shaabado taagan oo loogu talagalay inay u adkeyso wax kasta oo qarxin ah. Marka cadaadiska dareeruhu gaaro ama dhaafo cadaadiska heerka la qiimeeyay, waalka ayaa furma oo u ogolaanaya dareeraha inuu ka soo wareejiyo dhinaca cadaadiska sare una wareejiyo dhinaca cadaadiska hoose. Cadaadiska hoos u dhaca cadaadiska marinka wuxuu keeni doonaa inuu ku soo laabto booska uu xiran yahay. Hubi valves sidoo kale waxay ku badan yihiin warshadaha saliidda iyo gaasta, iyo sidoo kale bambooyinka, farsamaynta kiimikada, iyo codsiyada wareejinta dareeraha.
Inta badan, injineerada naqshadeeyayaasha waxay ku daraan valves check design engine-ka gantaaladooda. Sidaa darteed, doorka shaabadood ee dooxooyinkan ayaa aad muhiim u ah dhammaan howlgalka daahfurka. Shaabadda ka-hortagga garaacista ayaa loo isticmaalaa waalka hubinta si loo ilaaliyo dareeraha la cadaadiyo dhinaca cadaadiska sare iyadoo laga hortagayo in shaabadu ay ka buufiso guriga. Cadaadiska sare iyo isbeddellada degdega ah ee xiridda cadaadiska dusha sare, aad bay u dhib badan tahay in shaabadu ku hayso gurigeeda. Marka dusha sare ee shaabadeynta firfircoon ee qalabka laga sooco dibnaha daboolaya, shaabadda waxaa laga yaabaa in laga afuufo guriga sababtoo ah cadaadiska haraaga ah ee ku wareegsan shabadda. Caadi ahaan shaabadihii fadhiga, baloogyada fudud ee PTFE, ayaa loo isticmaalaa hubinta valvyada, laakiin waxqabadka shaabadahani waa mid aan is waafaqsanayn. Waqti ka dib, shaabadihii fadhigu si joogto ah ayey u qurmi doonaan, taasoo keenaysa daadid.
Shaabadihii aan qarxin ee Saint-Gobain Seals waxay ka soo jeedaan qaabaynta OmniSeal 103A waxayna ka kooban yihiin jaakad polymer ah oo leh tamar-geliyaha guga. Galka waxa uu ka samaysan yahay walxo Fluoroloy iska leh, halka guga laga samayn karo walxo ay ka mid yihiin birta aan la taaban karin iyo Elgiloy®. Marka loo eego xaaladaha shaqada ee waalka hubinta, guga waxaa lagu daweyn karaa kulaylka oo lagu nadiifin karaa hab gaar ah. Sawirka bidix wuxuu muujinayaa tusaale ahaan shaabadihii ka-hortagga qarxinta ee shaabadihii guud ee Saint-Gobain ee codsiyada shaabadda usha (xusuusnow: sawirkani wuu ka duwan yahay shaabadihii loo adeegsaday codsiyada jeegga dhabta ah, kuwaas oo si gaar ah loo qaabeeyey). Hubi codsiyada waalka Xirmooyinka ku jira waxay ku shaqayn karaan heerkul hoose ilaa 575°F (302°C) waxayna u adkeysan karaan cadaadiska ilaa 6,000 psi (414 bar).
Shaabada ka hortagta qaraxa OmniSeal ee loo isticmaalo matoorka gantaalada ee lagu baadho waxa loo isticmaalaa in lagu xidho gaasta la cadaadiyo iyo gaaska dareeraha ah ee heerkulka ka hooseeya -300°F (-184°C) ilaa 122°F (50°C). Shaabaddu waxay u adkeysan kartaa cadaadiska ku dhow 3,000 psi (207 bar). Walxaha gadhka Fluoroloy® waxa ay leeyihiin iska caabin xidhasho heersare ah, iska caabin qallafsan, isxigxiga hoose iyo awood heerkul aad u daran. OmniSeal® Kahortagga Qarxinta Seals waxaa loogu talagalay inay socodsiiso boqollaal wareegyo iyada oo aan wax daadin
Khadka sheyga OmniSeal® wuxuu bixiyaa nashqado kala duwan, sida 103A, APS, Spring Ring II, 400A, RP II iyo RACO™ 1100A, iyo sidoo kale noocyo kala duwan oo nashqado ah. Nashqadahaan waxaa ka mid ah shaabadeynta shaabadeynta walxaha daawaha ee fluorine ee kala duwan iyo ilo qaabeynta kala duwan. Xalalka xidhitaanka ee Saint-Gobain Seals ayaa loo adeegsaday gawaadhida riditaanka sida mishiinka gantaalada ee Atlas V (si loogu diro Curiosity Mars rover meel bannaan), gantaalada culus ee Delta IV iyo gantaalka Falcon 9. Xalalka ay sidoo kale loo isticmaalaa in warshadaha kale (saliid iyo gaaska, baabuurta, cilmiga nolosha, elektarooniga ah iyo warshadaha) iyo deegaanka saaxiibtinimo qalabka habka warshadaha rinjiyeynta, bamamka duritaanka kiimikada, saldhiga ugu horeysay ee gaaska subsea iyo analyzers kiimikada, iwm codsiga.
