Mavavu a mpira wa cryogenic okhala ndi ma bonaneti otalikirapo oyenera kugwira ntchito pa kutentha kotsika mpaka -196 ° C amapangidwa mwapadera kuti azitha kuthana ndi zovuta za cryogenic application. Ma valve awa amagwiritsidwa ntchito kwambiri m'mafakitale monga LNG (liquefied natural gas) processing, kupanga gasi wa mafakitale, ndi ntchito zina za cryogenic fluid zogwiritsira ntchito. ma valve nthawi zambiri amapangidwa kuchokera kuzinthu zapadera monga chitsulo chosapanga dzimbiri, chitsulo cha kaboni, kapena ma aloyi ena okhala ndi zinthu zotsika kutentha kuti zitsimikizire kugwira ntchito. ndi kukhulupirika m'madera a cryogenic.Kupanga Bonnet Yowonjezera: Boneti yowonjezera imapereka zowonjezera zowonjezera ndi chitetezo cha tsinde la valve ndi kulongedza kuti apitirize kugwira ntchito bwino pa kutentha kwambiri.Kusindikiza ndi Kuyika: Zida zosindikizira za valve ndi kulongedza zimapangidwira makamaka kuti zikhale zogwira mtima komanso zogwira ntchito. flexible pa kutentha kwa cryogenic, kupangitsa kutseka kolimba ndikuletsa kutayikira.Kuyesa ndi Kutsata: Ma valve awa amayesedwa mwamphamvu kuti atsimikizire kugwira ntchito ndi kutsata miyezo yamakampani a ntchito ya cryogenic. Chitetezo cha Ntchito: Mavavu a mpira wa cryogenic okhala ndi maboneti otalikirapo ndi ofunikira kuti asunge chitetezo chodalirika komanso chodalirika chakuyenda kwamadzimadzi a cryogenic, zomwe zimathandiza kuti chitetezo chizigwira ntchito m'machitidwe a cryogenic. m'pofunika kuganizira zinthu monga kugwirizana kwa zinthu, kupanikizika ndi kutentha, ndi kutsata miyezo ndi malamulo okhudza makampani.
API 6D trunnion ball valve ndi chinthu chopangidwa ndi valavu chomwe chimakwaniritsa zofunikira za American Petroleum Institute standard API 6D. Muyezowu umanena za mapangidwe, zinthu, kupanga, kuyang'anira, kukhazikitsa ndi kukonza zofunikira za API 6D trunnion mpira mavavu kuti zitsimikizire kuti ma valve a mpira ndi odalirika komanso odalirika, ndipo ndi oyenera madera osiyanasiyana a mafakitale monga mafuta ndi gasi. Mawonekedwe a API 6D trunnion mpira valve ndi awa:
1.Mpira wodzaza mpira umagwiritsidwa ntchito kuchepetsa kuthamanga kwa valve ndikuwongolera mphamvu yothamanga.
2.Vavu imagwiritsa ntchito njira ziwiri zosindikizira ndi ntchito yabwino yosindikiza.
3.Valavu ndi yosavuta kugwiritsa ntchito komanso yosalala, ndipo chogwiriracho chimalembedwa kuti chizindikiridwe mosavuta ndi wogwiritsa ntchito.
4.Mpando wa valve ndi mphete yosindikizira amapangidwa ndi kutentha kwapamwamba, kupanikizika kwambiri ndi zowonongeka zowonongeka, zomwe zimakhala zoyenera pazitsulo zosiyanasiyana zamadzimadzi.
5. Zigawo za valve ya mpira zimasiyanitsidwa bwino, zosavuta kukhazikitsa ndi kusamalira. API 6D trunnion mpira mavavu ndi oyenera nthawi m'munda mafakitale kuti ayenera kulamulira madzimadzi, kudula madzimadzi, ndi kusunga kukhazikika mtima, monga machitidwe madzi mapaipi mu mafuta, mankhwala, gasi, mankhwala madzi ndi zina.

Ntchito yogulitsa pambuyo pa valve yoyandama yoyandama ndiyofunikira kwambiri, chifukwa nthawi yake yokha komanso yogwira ntchito pambuyo pogulitsa imatha kutsimikizira kuti ikugwira ntchito nthawi yayitali komanso yokhazikika. Zotsatirazi ndi zomwe zili mkati mwa ntchito zogulitsa pambuyo pa mavavu ena oyandama a mpira:
1.Kuyika ndi kutumiza: Ogwira ntchito pambuyo pa malonda adzapita kumaloko kukayika ndi kukonza valve yoyandama ya mpira kuti atsimikizire kuti ikugwira ntchito mokhazikika komanso yokhazikika.
2.Maintenance: Nthawi zonse sungani valavu ya mpira yoyandama kuti muwonetsetse kuti ili bwino kwambiri ndikuchepetsa kulephera.
3.Kuthetsa mavuto: Ngati valavu yoyandama ya mpira ikulephera, ogwira ntchito pambuyo pa malonda adzachitapo kanthu pa nthawi yaifupi kwambiri kuti atsimikizire kugwira ntchito kwake.
4.Kusintha kwazinthu ndi kukonzanso: Poyankha zipangizo zatsopano ndi matekinoloje atsopano omwe akubwera pamsika, ogwira ntchito pambuyo pa malonda adzalimbikitsa mwamsanga kukonzanso ndi kukonzanso njira zothetsera makasitomala kuti awapatse mankhwala abwino a valve.
5. Maphunziro a chidziwitso: Ogwira ntchito pambuyo pa malonda adzapereka maphunziro a chidziwitso cha valve kwa ogwiritsa ntchito kuti apititse patsogolo kasamalidwe ndi kasamalidwe ka ogwiritsa ntchito pogwiritsa ntchito ma valve oyandama. Mwachidule, ntchito yogulitsa pambuyo pa valve yoyandama iyenera kutsimikiziridwa mbali zonse. Ndi njira iyi yokha yomwe ingabweretsere ogwiritsa ntchito bwino ndikugula chitetezo.
