Inkqubo yokutshiza umlilo yindlela esebenzayo yokukhusela umlilo.Amanzi anikezelwa yinkqubo yokubonelela ngamanzi, ahanjiswe kumbhobho ngamnye wokuhambisa amanzi, kwaye atshizwe ngesixhobo sokutshiza, kwaye umlilo ucinywe ngempumelelo, ngaloo ndlela uqinisekisa ukhuseleko lomntu.Iivalvu zinceda ukuthutha amanzi ukuze kuqhutywe ngempumelelo iinkqubo zokutshiza umlilo.Kule nqaku, siya kuncoma iivalve ezingasetyenziselwa kwiinkqubo zokutshiza, ngethemba lokukunceda uqonde ngcono kwaye ukhethe i-valve efanelekileyo.

Iivalvu zeSango

Ivalve yesango yivalve esebenza ngomgca.Isango liya ngqo phezulu okanye ngqo ezantsi ngesiqu sevalve ukuvula okanye ukuvala ivalve.Ivalve yesango sisivalo esiqhele ukusetyenziselwa ukujikeleza okanye ukusika imidiya.Ngoko ke, iivalve zesango zifanelekile kakhulu ukusetyenziswa kwiinkqubo zokubonelela ngamanzi.

Sincoma ukusebenzisa ivalve yesango lombane.Ulawulo olukude lunokufezekiswa ngokusebenzisa ii-activators zombane ukuqinisekisa ukhuseleko lomntu.

Iivalvu zeBhola

Ivalve yebhola yivalve yekota.Ibhola ijikeleza i-90 degrees kunye nesiqu sevalve ukuvula okanye ukuvala ivalve yebhola.Iivalve zebhola zilungele ukujikeleza, ukuvala, ukulawula ukuhamba kunye nokutshintsha indlela yokuhamba kwamanzi.Isetyenziswa ngokubanzi ekulawuleni amanzi, amanzi amdaka, amanzi okupholisa, umoya kunye neminye imithombo yeendaba.
Ingasetyenziswa kunye ne-actuator yombane kunye ne-pneumatic actuator ukuqonda ivalve yokulawula kude.

Iivalve zebhabhathane

Ivalve yebhabhathane yivalve yekota yokujika.Ipleyiti yebhabhathane ijikeleza i-90 degrees kunye nesiqu sevalve ukuvula okanye ukuvala ivalve.Ngokulungelelanisa i-angle yokutshintsha kweplate yebhabhathane, injongo yokulungelelanisa ukuhamba iyafezekiswa.Ngaphaya koko, iinxalenye zevalve yebhabhathane zinokutshintshwa ngokweemfuno zeprojekthi, ezifana nezitywina kunye neepleyiti zevalvu.
Ingasetyenziswa kunye ne-actuator yombane kunye ne-pneumatic actuators ngeenjongo zokulawula kude.

Oku ngasentla kukwaziswa kweevalvu ezinokuthi zisetyenziswe kwiinkqubo zokutshiza umlilo.Ukuba unazo naziphi na iimfuno zeevalvu, wamkelekile ukuba uqhagamshelane nathi ngesona sisombululo sevalve.
