Amavalvu Ebhola Ashiselwe Ngokugcwele (Okuhlinzeka Ngokushisisa Kuphela)
Izici
I-valve yebhola eshiselwe ucezu olulodwa, akukho ukuvuza kwangaphandle nezinye izinto.
▪ Ubuchwepheshe basekhaya obuhamba phambili, ukunganakekeli kanye nempilo ende yesevisi.
Inqubo yokushisela ihlukile, inezimbotshana ezibalulekile, azinawo amabhamuza, umfutho ophakeme kanye nokuvuza kweqanda emzimbeni.
▪ Ukusebenzisa ibhola lensimbi engagqwali elisezingeni eliphezulu, isakhiwo sokuvala sohlobo lwe-double-layer support, ukusekelwa kwebhola kungokwesayensi futhi kunengqondo.
▪ I-gasket yenziwe nge-Teflon, i-nickel, i-graphite nezinye izinto, futhi i-carbonized.
▪ Umthombo wevalvu unezindleko eziphansi futhi kulula ukuwuvula nokusebenza.
Ifakwe imbobo yokujova ugrisi ngendlela yevalvu yokuhlola engavimba isivalo sokuthambisa singabuyeli emuva ngaphansi kwengcindezi ephezulu.
Ivalvu ifakwe izinto zokungena, ukudonsa amanzi kanye nokuvikela kuye ngokwezidingo zohlelo lwamapayipi.
▪ Imishini yokukhiqiza ye-CNC, ukwesekwa okuqinile kwezobuchwepheshe, ukufanisa okunengqondo kwesofthiwe nehadiwe.
▪ Usayizi we-butt weld ungaklanywa futhi ukhiqizwe ngokuya ngesicelo sekhasimende.
Ukuhlolwa Komlilo: API 607. API 6FA
Izindlela Zokusebenza Ezihlukahlukene
▪ Izinhlobo ezahlukene zama-valve actuator zingahlinzekwa: manual, pneumatic, electric, hydraulic, pneumatic hydraulic linkage.Imodeli ethile ikhethwa ngokuya nge-torque ye-valve.

Isakhiwo
Ivalufu Egxilile Eshiselwe Ngokugcwele Yokuhlinzeka Ngokushisa (Uhlobo olugcwele lwebhore)
Ivalufu Egxilile Eshiselwe Ngokugcwele Yokuhlinzeka Ngokushisa (Uhlobo olujwayelekile lwebhore)
Ubukhulu
Ivalvu Yebhola Eshiselwe Ngokugcwele Eneziphetho Ezinamaphiko (Yokuhlinzeka Ngokushisa Kuphela)
Isicelo
▪ Ukunikezwa kokushisisa okuphakathi: amapayipi aphumayo, izintambo ezinkulu, nemigqa yamagatsha yemishini yokushisisa emikhulu.
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.
