Amavalvu Ebhola Ashiselwe Ngokugcwele (Uhlobo Olugxilile Lwe-Cylindrical)
Izici
▪ Izinga Lempahla: I-NACE MR0175.
▪ Ukuhlolwa Komlilo: API 607. API 6FA.
▪ Isakhiwo somzimba wamavalvu angamacylindrical sinezinzuzo zenqubo yokukhiqiza elula, ukuhlanganisa nokubeka endaweni efanele, ifa elilula elidingekayo ekwenzeni okungenalutho, kanye nokusetshenziswa kalula kwepuleti lokusekela ukulungisa ibhola.
▪ Ifomu lokuhlanganisa nokushisela: Imizimba emithathu iyahlanganiswa bese ishiselwa ngamashisela ama-symmetrical longitudinal amabili noma imizimba emibili ihlanganiswa futhi ishiselwe nge-weld eyodwa ye-longitudinal.Isakhiwo sinokusebenza okuhle futhi silungele ukufakwa kwe-valve stem.Ifaneleka ngokukhethekile kuma-diameter amakhulu wonke ama-valve ebhola ashiselwe.(izidumbu ezimbili zisebenza ku-diameter encane yonke i-valve yebhola eshiselwe, futhi imizimba emithathu isetshenziswa kububanzi obukhulu kuwo wonke ama-valve ebhola ashiselwe).
▪ Imishini yokukhiqiza ye-CNC, ukwesekwa okuqinile kwezobuchwepheshe, ukufanisa okunengqondo kwesofthiwe nehadiwe.
Isakhiwo
Amavalvu Ebhola Enziwe Ama-Cylindrical Forged Welded Ball (Uhlobo olugcwele lokubhoboza)
Ubukhulu
Isibambo esisebenza ngesandla se-Worm gear
Isicelo
▪ Igesi yasemadolobheni: ipayipi elikhipha igesi, ulayini oyinhloko kanye nepayipi lokuhlinzeka ngegatsha njll.
▪ Isishintshi sokushisa: ukuvulwa nokuvala amapayipi namasekhethi.
▪ Imboni yensimbi: Ukulawulwa okuhlukahlukene koketshezi, ipayipi lokulahla igesi engcolile, ipayipi lokuhambisa igesi nokushisa, ipayipi lokuhambisa uphethiloli.
▪ Imishini eyahlukene yezimboni: amapayipi okushisa ahlukahlukene, igesi yezimboni namapayipi ashisayo.
Ukufakwa
▪ Izingxenye zokushisela zawo wonke ama-valve ebhola ensimbi asebenzisa ukushisela ngogesi noma ukushisela ngesandla.Ukushisa okweqile kwegumbi le-valve kufanele kugwenywe.Ibanga phakathi kokuphela kwe-welding ngeke libe lifushane kakhulu ukuze kuqinisekiswe ukuthi ukushisa okukhiqizwa ohlelweni lokushisela ngeke konakalise izinto zokuvala.
▪ Wonke amavalvu kufanele avulwe ngesikhathi sokufakwa.
