Ama-butterfly ama-valves anikeza ukulawula okungasindi futhi okunesilinganiso sokulawulwa kwezindleko eziphansi ngaphezulu kokugeleza kwamanzi ohlelweni lokufafaza umlilo nezinhlelo zokuma
I-valve yamabhabhathane ihlukanisa noma ilawula ukuhamba koketshezi ngezinhlelo zokufaka amapayipi. Ngenkathi zingasetshenziswa ngotshwala, amagesi, kanye nama-semi-solids, ama-butterfly ama-valves okuvikela umlilo asebenza njengama-valves okulawula avule noma avale ukugeleza kwamanzi asebenza amapayipi asebenza ngomlilo we-sprinkler noma amasistimu wokuma.
I-valve evevere yokuvikelwa komlilo iqala, iyama, noma iguqukele ukugeleza kwamanzi ngokujikeleza kwe-disc yangaphakathi. Lapho i-disc iguqulwa ngokufana nokugeleza, amanzi angadlula ngokukhululeka. Jikelezisa amadigri angama-disc 90, kanye nokunyakaza kwamanzi ohlelweni lwamapayipi okuma. Le disc emfishane ingahlala endleleni yamanzi ngaso sonke isikhathi ngaphandle kokunciphisa kakhulu ukuhamba kwamanzi nge-valve.
Ukujikeleza kwe-disc kulawulwa yisandla. Isandla sijikeleza induku noma isiqu, esiguqula i-disc futhi ngasikhathi sinye sijikeleza isibonakaliso sesikhundla - imvamisa isiqephu esinemibala ekhanyayo esinamathela ngaphandle kwe-valve - ekhombisa ukuthi i-disc ibheke kanjani. Le nkomba ivumela isiqinisekiso sokubheka nje ukuthi i-valve ivuliwe noma ivaliwe.
Isikhombi sesikhundla sidlala indima ebalulekile ekugcineni izinhlelo zokuvikela umlilo zisebenza. Ama-butterfly ama-valves asebenza njengezindlela zokulawula ezikwazi ukuvala amanzi ukuze afake umlilo wezinhlelo zokufafaza noma zokuma noma izingxenye zazo. Izakhiwo zonke zingashiywa zingavikeleki lapho i-valve yokulawula ishiywe kungahlosiwe. Isikhombi sesikhundla sisiza abasebenza ngomlilo kanye nabaphathi bendawo ukuthi babone i-valve evaliwe futhi baphinde bayivule ngokushesha.
Ama-valves we-butterfly amaningi wokuvikelwa komlilo nawo afaka ukushintshwa kwe-temple ye-elektroniki okuxhumana nephaneli yokulawula bese uthumela i-alamu lapho i-disc ye-valve ijikeleza. Imvamisa, zifaka izinguquko ezimbili ze-tamper: eyodwa yokuxhumana nephaneli yokulawula umlilo nomunye ngokuxhuma kudivayisi elula, njengensimbi noma uphondo.
