Iivalvu zebhabhathane ziivalvu ezijika ikota ezisetyenziselwa ukulawula ukuhamba kwamanzi. Idiski yesinyithi ekwiivalvuUmzimba umi nkqo kulwelo kwindawo evaliweyo kwaye ujikeleziswa ngekota ukuze ulingane nolwelo kwindawo evulekileyo ngokupheleleyo. Ukujikeleza okuphakathi kuvumela ukulungiswa kokuhamba kolwelo. Zisetyenziswa kakhulu kwezolimo nakwizicelo zonyango lwamanzi okanye amanzi amdaka kwaye zezinye zezona ntlobo zeevalvu zixhaphakileyo nezaziwayo.

Iingenelo zeivalvu yebhabhathane
Iivalvu zebhabhathane zifana neevalvu zebhola, kodwa zineengenelo ezininzi. Zincinci kwaye, xa zisebenza ngomoya, zinokuvula kwaye zivaleke ngokukhawuleza kakhulu. Idiski ikhaphukhaphu kunebhola, kwaye ivalvu ayifuni nkxaso yolwakhiwo engaphezulu kunevalvu yebhola enobubanzi obufanayo. Iivalvu zebhabhathane zichaneke kakhulu, nto leyo ebanika ithuba kwizicelo zoshishino. Zithembekile kakhulu kwaye azidingi kugcinwa kakhulu.

Iingxaki zevalvu yebhabhathane
Enye ingxaki ngeevalvu zeebhabhathane kukuba inxalenye ethile yediski ihlala ikhona kwindlela esebenza ngayo, nokuba ivuliwe ngokupheleleyo. Ke ngoko, ukusebenzisa ivalvu yeebhabhathane kuya kuhlala kudala iswitshi yoxinzelelo kwivalvu, nokuba ibekwe njani na.

Iivalvu zebhabhathane ezisebenza ngombane, nge-pneumatic okanye ngesandla

Iivalvu zebhabhathaneinokwenziwa ukuze isebenze ngesandla, ngombane okanye ngomoya. Iivalvu zomoya zisebenza ngokukhawuleza. Iivalvu ze-elektroniki kufuneka zithumele isignali kwibhokisi yegiya ukuze zivuleke okanye zivalwe, ngelixa iivalvu zomoya zinokwenziwa nge-single-activated okanye nge-dual-activated. Iivalvu eziqhutywa nge-single-activated zihlala zisetwa ukuze zifune isignali ukuba ivuleke nge-failsafe, oko kuthetha ukuba xa umbane ulahlekile, ivalvu ibuyela kwindawo evaliweyo ngokupheleleyo. Iivalvu zomoya eziqhutywa nge-dual-activated azifakwanga spring kwaye zifuna isignali ukuze zivuleke kwaye zivalwe.

Iivalvu zebhabhathane ezisebenzisa umoya ngokuzenzekelayo zithembekile kwaye zihlala ixesha elide. Ukunciphisa ukuguguleka kuphucula umjikelo wobomi beevalvu, ngaloo ndlela kunciphisa iindleko zokusebenza ebezinokulahleka kwiiyure zokusebenza zokugcina ivalvu.
