Kunezinhlobo eziningi zamavalvu ebhabhathane, okuhlanganisa ukunqamula okusheshayo kanye nokulungiswa okuqhubekayo. Isetshenziswa kakhulu kumapayipi amakhulu anomfutho ophansi noketshezi kanye negesi. Ifaneleka ngezikhathi lapho izidingo zokulahlekelwa yingcindezi zingekho phezulu, ukulungiswa kokugeleza kuyadingeka, kanye nezidingo zokuvula nokuvala zishesha; ngokuvamile izinga lokushisa lingaphansi kuka-300 ℃ kanti ingcindezi ingaphansi kuka-40 kg (amavalvu ebhabhathane ngokuvamile asebenzisa ingcindezi ephansi, njengalawo asekhaya. Akuvamile ukufeza i-CL600). I-medium ivame ukusetshenziselwa amanzi kanye negesi, kanti i-medium ayidingi. I-medium e-granular ingasetshenziswa futhi.
Njengevalvu yebhabhathane evaliwe, yaletha intuthuko esheshayo ngemva kokuvela kwerabha yokwenziwa, ngakho-ke iwuhlobo olusha lwevalvu yokuvala. Ezweni lethu kuze kube ngawo-1980, amavalvu ebhabhathane ayesetshenziswa kakhulu kumavalvu anomfutho ophansi, futhi isihlalo sevalvu sasenziwa ngerabha yokwenziwa. Ngawo-1990, ngenxa yokwanda kokushintshana namazwe angaphandle, amavalvu ebhabhathane aqinile (i-metal-seal) athuthuka ngokushesha. Njengamanje, kunezimboni eziningi zamavalvu ezingakhiqiza amavalvu ebhabhathane aqinile anomfutho ophakathi nendawo, okwenza insimu yokusetshenziswa kwamavalvu ebhabhathane ibe banzi.
Izinto ezingasetshenziswa yivalvu yebhabhathane futhi ziyilawule ngamanzi, amanzi ahlanganisiwe, amanzi ajikelezayo, indle, amanzi olwandle, umoya, igesi, igesi yemvelo ewuketshezi, impuphu eyomile, udaka, uqweqwe lwezithelo kanye nezingxube zezinto eziqinile ezilengayo.
Ama-valve e-Butterfly afanelekela ukulawulwa kokugeleza. Njengoba ukulahlekelwa kwengcindezi ye-valve ye-butterfly epayipini kukhulu kakhulu, cishe kuphindwe kathathu kune-valve yesango. Ngakho-ke, lapho ukhetha i-valve ye-butterfly, ithonya lokulahlekelwa kwengcindezi yesistimu yepayipi kufanele licatshangelwe ngokugcwele, futhi amandla epuleti le-butterfly ukumelana nengcindezi ye-medium yepayipi lapho ivaliwe kufanele futhi acatshangelwe. Ubulili. Ngaphezu kwalokho, kubalulekile ukucabangela ukulinganiselwa kwezinga lokushisa lokusebenza okungamelana nezinto zesihlalo se-valve elastic emazingeni okushisa aphezulu. Ubude besakhiwo kanye nokuphakama okuphelele kwe-valve ye-butterfly kuncane, isivinini sokuvula nokuvala siyashesha, futhi sinezici ezinhle zokulawula uketshezi. Isimiso sesakhiwo se-valve ye-butterfly sifaneleka kakhulu ekwenzeni ama-valve amakhulu. Uma i-valve ye-butterfly idingeka ukulawula izinga lokugeleza, into ebaluleke kakhulu ukukhetha kahle usayizi nohlobo lwe-valve ye-butterfly ukuze isebenze kahle nangendlela ephumelelayo.
INortech ingenye yabakhiqizi bama-valve ezimboni abahamba phambili eShayina abanesitifiketi sekhwalithi se-ISO9001.
