Ixabiso eliphantsi langaphambi koNyaka oMtsha le-ductile iron halar coating ene-double flange concentric butterfly valve esemgangathweni ophezulu eyenziwe eTshayina

Ivalvu yeButterfly ejikelezayo kabini: iivalvu zebhabhathane ezijijekileyo zithatha indawo ebalulekileyo ngenxa yokuguquguquka kwazo nokusebenza kwazo kakuhle. Eli nqaku lijolise ekukhanyiseni ukubaluleka kunye neempawu zale valve ingaqhelekanga, ingakumbi kwicandelo lokunyanga amanzi. Ukongeza, siza kuxoxa ngendlela ukuthengiswa ngqo kwefektri kweevalvu zebhabhathane ezinkulu ezijijekileyo ezibonelela ngayo ngeenzuzo ezingenakuthelekiswa nanto ngexabiso kunye nomgangatho. Eyaziwa ngoyilo lwayo olulula kodwa olusebenzayo, le valve inediski ebekwe phakathi kweziphelo ezimbini zeflange. Utywino oluqinileyo phakathi kwediski nomzimba luqinisekisa ukuvuza okuncinci, okwenza ukuba ilungele usetyenziso olufuna ukuvalwa ngokupheleleyo. Ukongeza, uyilo lwayo oluncinci kunye nobunzima obulula kwenza kube lula ukufakela nokugcina.

Xa kufikwa ekunyangweni kwamanzi, iivalvu zebhabhathane ezijijekileyo ezijijekileyo zibonakala ziluncedo kakhulu kushishino. Njengoko isidingo solawulo lwamanzi olusebenzayo siqhubeka sisanda, le valve iye yaba sisisombululo esithembekileyo. Isetyenziswa kakhulu ekunikezelweni kwamanzi, ekunyangweni kwamanzi amdaka, kwizityalo zokukhupha ityuwa nakwamanye amasimi. Amandla ayo okulawula ngokuchanekileyo ukuhamba kwamanzi ngelixa iqinisekisa ukwehla koxinzelelo oluphantsi kuyenza ibe yinxalenye ebalulekileyo kwizibonelelo zonyango lwamanzi.
