Kunezinhlobo eziningi zamavalve ovemvane, okuhlanganisa ukunqanyulwa okusheshayo nokulungiswa okuqhubekayo.Isetshenziselwa ikakhulukazi uketshezi kanye negesi amapayipi anobubanzi obukhulu obuphansi.Ifanele izikhathi lapho izidingo zokulahlekelwa kwengcindezi zingekho phezulu, ukulungiswa kokugeleza kuyadingeka, futhi izidingo zokuvula nokuvala ziyashesha;ngokuvamile izinga lokushisa lingaphansi kuka-300 ℃ futhi ingcindezi ingaphansi kuka-40 kg (amavalvu ovemvane ngokuvamile asebenzisa umfutho ophansi, njengasekhaya. Akuvamile ukufeza i-CL600).I-medium ngokuvamile isetshenziselwa amanzi negesi, kanti i-medium ayifuni.I-Granular medium nayo ingasetshenziswa.
Njenge-valve uvemvane evalekile, yaletha intuthuko ngokushesha ngemva kokuvela kwenjoloba yokwenziwa, ngakho iwuhlobo olusha lwe-valve yokuvala.Ezweni lakithi kuze kube yiminyaka yawo-1980, ama-butterfly valves ayesetshenziselwa ikakhulukazi ama-valve anengcindezi ephansi, futhi isihlalo se-valve senziwa ngerabha yokwenziwa.Ngawo-1990, ngenxa yokwanda kokuhwebelana namazwe angaphandle, ama-valve uvemvane oqinile (insimbi-seal) athuthuka ngokushesha.Njengamanje, kunezimboni eziningi zama-valve ezingakhiqiza ama-valve uvemvane ane-medium-sealed metal-sealed stably, okwenza inkambu yokufakwa kwe-butterfly ibe banzi.
Imithombo yezindaba engathuthwa futhi ilawule i-valve uvemvane ngamanzi, amanzi ajiyile, amanzi ajikelezayo, indle, amanzi olwandle, umoya, igesi, igesi yemvelo ewuketshezi, impushana eyomile, udaka, i-pulp yezithelo nezingxube ezinokuqina okumisiwe.
Ama-valve e-butterfly afanele ukulawulwa kokugeleza.Njengoba umfutho we-valve uvemvane epayipini umkhulu uma kuqhathaniswa, cishe uphindwe kathathu kune-valve yesango.Ngakho-ke, lapho ukhetha i-valve ye-butterfly, ithonya lokulahlekelwa kwengcindezi yesistimu yepayipi kufanele licatshangelwe ngokugcwele, futhi amandla epuleti ye-butterfly ukumelana nokucindezela kwepayipi lepayipi lapho ivaliwe kufanele futhi icatshangelwe.Ucansi.Ngaphezu kwalokho, kuyadingeka ukucabangela umkhawulo wokushisa okusebenzayo ukuthi impahla yesihlalo se-valve elastic ingamelana namazinga okushisa aphezulu.Ubude besakhiwo nokuphakama okuphelele kwe-valve ye-butterfly kuncane, isivinini sokuvula nokuvala siyashesha, futhi sinezici ezinhle zokulawula uketshezi.Isimiso sesakhiwo se-valve ye-butterfly ifaneleka kakhulu ekwenzeni ama-valve anobubanzi obukhulu.Lapho i-valve ye-butterfly idingeka ukulawula izinga lokugeleza, into ebaluleke kakhulu ukukhetha kahle ubukhulu kanye nohlobo lwe-valve butterfly ukuze lusebenze kahle nangempumelelo.
I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.
