Isistimu yokufafaza umlilo iyindlela esebenzayo yokuvikela umlilo.Amanzi anikezwa uhlelo lokuphakelwa kwamanzi, asakazwe epayipini ngalinye lokusabalalisa amanzi, futhi afuthwe ngomshini wokufafaza, futhi umlilo ucishwa ngempumelelo, ngaleyo ndlela kuqinisekiswe ukuphepha komuntu siqu.Amavalvu asiza ukuthutha amanzi ukuze kusebenze ngempumelelo izinhlelo zokufafaza umlilo.Kulesi sihloko, sizoncoma ama-valve angasetshenziswa ezinhlelweni zokufafaza, ngethemba lokukusiza ukuthi uqonde kangcono futhi ukhethe i-valve efanele.

Amavalvu esango

I-valve yesango iyi-valve yokusebenza eqondile.Isango lihamba liqonde phezulu noma liqonde phansi nesiqu se-valve ukuvula noma ukuvala i-valve.I-valve yesango i-valve evame ukusetshenziselwa ukujikeleza noma ukusika imidiya.Ngakho-ke, ama-valve esango afaneleka kakhulu ukusetshenziswa ezinhlelweni zokuhlinzeka ngamanzi.

Sincoma ukusebenzisa i-valve yesango likagesi.Isilawuli kude singatholwa ngama-actuator kagesi ukuze kuqinisekiswe ukuphepha komuntu siqu.

Ama-Ball Valves

I-valve yebhola iyi-valve yokujika yesine.Ibhola lizungeza amadigri angu-90 ngesiqu se-valve ukuvula noma ukuvala i-valve yebhola.Ama-valve ebhola afanele ukuzungeza, ukuvala, ukulawula ukugeleza nokushintsha isiqondiso sokugeleza koketshezi.Isetshenziswa kakhulu ekulawuleni amanzi, amanzi angcolile, amanzi okupholisa, umoya kanye neminye imithombo yezindaba.
Ingasetshenziswa ne-actuator kagesi kanye ne-pneumatic actuator ukubona i-valve yokulawula kude.

Ama-Butterfly Valves

I-valve yevemvane iyi-valve yokujika yesine.Ipuleti uvemvane lizungeza amadigri angu-90 nesiqu se-valve ukuvula noma ukuvala i-valve.Ngokulungisa i-angle yokushintsha yepuleti uvemvane, inhloso yokulungisa ukugeleza iyafezeka.Ngaphezu kwalokho, izingxenye ze-valve uvemvane zingashintshwa ngokuya ngezidingo zephrojekthi, njengezigxivizo namapuleti e-valve.
Ingasetshenziswa nama-actuator kagesi nama-actuator womoya ngezinjongo zokulawula kude.

Okungenhla ukwethulwa kwamavalvu angasetshenziswa ezinhlelweni zokufafaza umlilo.Uma unezidingo zamavalvu, wamukelekile ukuthintana nathi ukuthola isisombululo esingcono kakhulu samavalvu.
