Munzvimbo zhinji dzepasi, kubvisa munyu mugungwa kuri kusisiri chinhu cheumbozha, kuri kuva chinhu chinodiwa. Kushaikwa kwemvura yekunwa ndicho chinhu chikuru chinokanganisa hutano munzvimbo dzisina mvura yakakwana, uye munhu mumwe chete pavanhu vatanhatu pasi rose haana mvura yekunwa yakachengeteka. Kudziya kwepasi rose kuri kukonzera kusanaya kwemvura uye kunyunguduka kwechando, zvichireva kuti mvura yepasi iri kunyangarika nekukurumidza. Nzvimbo huru dzeAsia, United States (kunyanya California) nedzimwe nzvimbo dzeSouth America dziri panjodzi. Mamiriro ekunze asingafanoonekwi, umo mafashamo nekusanaya kwemvura kunoitika kakawanda, zvinoita kuti zviome kufanotaura kudiwa kwekubvisa munyu mugungwa.
Saka mumusika wekubvisa munyu mumvura yegungwa, kuomarara kuri kuramba kuchiwedzera kwemaitiro ekushanda kunoda kuti mavharuvhu emabhatafura ave akavimbika uye akasimba, Tianjin Tanggu Water-Seal Valve Co., Ltd inopa mhando dzakasiyana-siyana uye dzinodhura.
Imwe mhando yevharuvhu yedu yemvura yegungwa ine muviri webhuronzi wealuminium nedhisiki ine NBR liner, zvichiita kuti ive mhinduro inoshanda pakushandiswa kwemvura. Yakakodzera kumanikidzwa kunosvika 16 bar uye tembiricha iri pakati pe -25°C ne +100°C, vharuvhu iyi yebhuronzi inopa kuvhura nekuvharika nekukurumidza nekuyerera kwakazara munzira dzese uye kudzima kwakasimba. Uyezve, jira rinotambanukira kumeso rinoshanda segasket, zvinoreva kuti magaskets eflange akasiyana haadiwi.
Uye tinogonawo kupa duplex steel disc, kana simbi disc rabha yakafukidzwa, kana disc Halar yakafukidzwa nemamiriro akasiyana.
Mavharuvhu edu nemaactuator anofukidza matambudziko makuru ehunyanzvi anosangana nawo mumafekitori ekubvisa munyu, akadai semamiriro ezvinhu anoparadza kubva munharaunda uye kubva mumunyu wakawanda wemvura yegungwa.
