Valavu ya Mpira wa Cryogenic

Valavu ya cryogenic iyi imagwiritsidwa ntchito pa LNG, gasi wachilengedwe, ndi mapaipi ena otentha pang'ono. Ndi yoyenera kugwira ntchito pa kutentha kochepa komanso kuthamanga kwambiri ndipo idapangidwa motsatira miyezo ya API 6D.
Chida cholumikizira ma valve ndi ASTM A350 LF2 chitsulo cha carbon chomwe chimakhala ndi kutentha kochepa. Chida ichi chimagwiritsidwa ntchito kwambiri pa ma valve a cryogenic chifukwa chimasunga kulimba bwino pa kutentha kochepa. Kukula kwa ma valve ndi mainchesi 14 (DN350) ndi pressure rating ya Class 900 / PN150. Mtundu wolumikizira ndi RTJ flanged, ndipo valavu imayendetsedwa ndi gearbox kuti ikhale yosavuta kugwiritsa ntchito pa kukula kwakukulu.
Kapangidwe ka bonnet kotalika kamagwiritsidwa ntchito kuchepetsa mphamvu ya zinthu zotentha pang'ono pamalo opakira tsinde. Vavu imagwiritsa ntchito kapangidwe ka mpira womangiriridwa ndi trunnion, komwe kumathandiza kuchepetsa mphamvu yogwirira ntchito ndi kuwonongeka kwa mipando panthawi yogwira ntchito. Kapangidwe kamtunduwu kamagwiritsidwa ntchito kwambiri m'mapayipi akuluakulu komanso amphamvu kwambiri.
Valavu ingagwiritsidwe ntchito m'malo osungiramo magetsi a LNG, mapaipi a gasi, mafakitale a petrochemical, makina osungiramo zinthu, ndi ntchito zina zamafakitale zotsika kutentha kuti zizimitse ndikuwongolera kayendedwe ka madzi.
