Ezingxenyeni eziningi zomhlaba, ukuncishiswa ukuyeka ukuba yinto yokunethezeka, kuba yisidingo. Ukuntuleka kwamanzi okuphuza akulona. 1 Isici esithinta kakhulu impilo ezindaweni ngaphandle kokuphepha kwamanzi, futhi munye kubantu abayisithupha abakwazi ukufinyelela emanzi okuphuza aphephile. Ukushisa komhlaba wonke kubangela isomiso nokuncibilika kweqhwa, okusho ukuthi amanzi angaphansi komhlaba anyamalala ngokushesha. Ikakhulu engcupheni izingxenye ezinkulu ze-Asia, i-United States (ikakhulukazi iCalifornia) nezingxenye zaseNingizimu Melika. Amaphethini wesimo sezulu esingalindeleki, lapho izikhukhula kanye nesomiso esenzeka khona imvamisa enkulu, kwenze kube nzima ukubikezela isidingo sokudilisela.
Ngakho-ke emakethe yokuhlanza amanzi olwandle ubunkimbinkimbi obukhulayo bezinqubo ezifunwa ngama-butterfly ama-valves athembeke kakhulu futhi aqinile, uTianjin Tanggu Water-Seal-Seal Valve Co, Ltd anikeze ibanga elibanzi nelingabizi.
Uhlobo olulodwa i-valve ye-baterfly ye-waterfly yethu igcwele umzimba we-aluminium bronze ne-disc nge-NBR Liner, okwenza kube yisixazululo esisebenzayo sezicelo zasolwandle. Ilungele ingcindezi yokusebenza efinyelela kubha engu-16 kanye nobubanzi bokushisa obuphakathi kuka-25 ° C kanye no-100 ° C, leli ° kuphela i-valve linikeza ukuvulwa okusheshayo nokuvala ngokuqondile. Ngaphezu kwalokho, i-lining efinyelela ebusweni isebenza njenge-gasket, okusho ukuthi ama-gaskets ahlukile we-flange awadingeki.
Futhi futhi singanikela nge-Druplex disc, noma irobho ye-disc disc embozwe, noma i-disc halar ehlanganiswe ngesimo esihlukile.
Ama-valves ethu kanye nama-actuators ethu ahlanganisa izinselelo ezinkulu zobuchwepheshe ezihlangabezana nazo ezitshalweni zokuncishiswa, njengezimo ezilimazayo ezivela emvelweni nakusosalweni oluphezulu lwamanzi olwandle.
