Ivalve yokujonga i-API 6D Swing ithintela i-medium kumbhobho ukuba ibuye umva.ivalve evula okanye evala ngokuqukuqela kunye nokunyanzeliswa kwe-medium ukukhusela i-medium ukuba ingabuyeli ngasemva ibizwa ngokuba yi-valve yokukhangela.Iivalvu zokukhangela zezodidi lweevalvu ezizenzekelayo, ezisetyenziswa ikakhulu kwimibhobho apho i-medium ihamba kwicala elinye, kwaye ivumela kuphela i-medium ukuba ihambe kwicala elinye ukuthintela iingozi.Olu hlobo lwevalve kufuneka lufakwe ngokubanzi ngokuthe tye kumbhobho.
Ivalve yokujonga i-Swing ithatha isakhiwo sokujingi se-rocker eyakhelwe-ngaphakathi.Zonke iindawo zokuvula kunye nokuvala i-valve zifakwe ngaphakathi komzimba we-valve, kwaye ungangeni kumzimba we-valve.Ngaphandle kwe-gasket yokutywina kunye nendandatho yokutywina kwi-flange ephakathi, yonke Akukho ndawo yokuvuza, ukuthintela ukuvuza kwevalve.Ingalo yokujingi yevalve yokujonga ujingi ithatha ulwakhiwo lonxibelelwano olungqukuva kunxibelelwano phakathi kwengalo yerocker kunye ne-valve flap, ukuze i-flap yevalve ibe nenqanaba elithile lenkululeko ngaphakathi kuluhlu lwee-degrees ezingama-360, kwaye kukho indawo yokulandela umkhondo efanelekileyo. imbuyekezo.
Ngokukhethwa kwezinto ezahlukeneyo, i-valve yokukhangela i-swing ingasetyenziswa kumajelo ahlukeneyo afana namanzi, umphunga, ioli, i-nitric acid, i-acetic acid, i-media oxidizing enamandla kunye ne-urea.Isetyenziswa kakhulu kwimibhobho efana nepetroleum, ikhemikhali, amayeza, isichumisi, kunye namandla ombane.
