Amavalvu Ebhola Ashiselwe Ngokugcwele (Uhlobo Olungcwatshwe Ngokuqondile)
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.
Ubude bomzimba wevalvu eshiselwe ngokuqondile bunganqunywa ngokuya ngokujula okugqitshiwe.
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.
Ivalve Yebhola Eshiselwe Ngokugcwele (Ingcwatshwe Ngokuqondile Ngohlobo Lokufakwa Kwangaphambi Kokufukamela)
Ukufakwa kwezicelo endaweni yokuhlinzeka ngokushisisa, ukupholisa kanye nezinhlelo zokufudumeza, igesi yedolobha.
▪ Okumaphakathi: amanzi, umoya, uwoyela kanye nolunye uketshezi olungahlangene ngamakhemikhali ne-carbon steel.
Ubukhulu
Ivalve Yebhola Eshiselwe Ngokugcwele (Uhlobo Olungcwatshwe Ngokuqondile Futhi Oluhlakazekile)
▪ Ukufakwa kwepayipi legesi yemvelo, igesi yedolobha.
▪ Okumaphakathi: igesi yemvelo, igesi yamalahle, igesi nolunye uketshezi olungasabelani ngamakhemikhali ne-carbon steel.
Ubukhulu
I-Buried Working Condition Design
▪ Kumavalvu asetshenziswa ngaphansi kwezimo ezingaphansi komhlaba, setha ama-valve extension rods, amapayipi okunwetshwa ukuze agcinwe (amapayipi okukhipha igesi nhlangothi zombili + amapayipi omjovo kagrisi ezinhlangothini zombili zesihlalo sevalvu + ipayipi lokukhucululwa kwendle ngaphansi kwe-valve body) namavalvu okulawula ukwenza indawo yokusebenza kwevalvu phansi Ingxenye engenhla kulula ukuyisebenzisa.I-asphalt emelana nokubola noma ukuvikelwa kwe-epoxy resin phezu kwe-valve, i-jumper yepayipi esendaweni kanye nezinyathelo zokuvikela izimo eziphuthumayo, zivumelanisa nendawo engcwatshiwe.
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.
