Izinhlelo zokucisha umlilo zibalulekile ekuvikeleni izimpilo nempahla ezingozini zomlilo. Ingxenye ebalulekile yalezi zinhlelo wuxhaxha lwama-valve asetshenziselwa ukulawula, ukulawula nokuqondisa ukugeleza kwamanzi. Ukuqonda izinhlobo ezahlukene zamavalvu kanye nemisebenzi yawo ngaphakathi kwesistimu yokuvikela umlilo kubalulekile kukho kokubili ukwakheka nokugcinwa. Ngezansi, sizohlola amanye ama-valve asetshenziswa kakhulu kumasistimu okulwa nomlilo.
1. Amavalvu esango
Ama-valve esango aphakathi kwezinto ezisetshenziswa kakhulu ezinhlelweni zokuvikela umlilo. Lawa ma-valve asebenza ngokuphakamisa isango (idiski eliyisicaba noma elimise okwe-wedge) liphume endleleni yokugeleza kwamanzi. Uma evuleke ngokugcwele, amavalvu esango avumela ukugeleza kwamanzi okungavimbekile, okuwenza alungele ukuhlukanisa izingxenye zenethiwekhi yamapayipi okuvikela umlilo. Ngokuvamile zisetshenziswa ezinhlelweni lapho i-valve ivuliwe noma ivalwe ngokugcwele. Amavalvu esango, ikakhulukazi lawo anomklamo we-OS&Y (Outside Screw and Yoke), ayakhethwa ngoba isimo sawo esivulekile noma esivaliwe singanqunywa kalula ngokuma kwesikulufu nejoka.
2. Hlola ama-Valves
Ama-valve okuhlola abalulekile ekuvimbeleni ukubuyela emuva ezinhlelweni zokulwa nomlilo. Avumela amanzi ukuthi ageleze aye ohlangothini olulodwa kuphela, avale ngokuzenzakalelayo uma ukugeleza kuhlehla. Lo msebenzi ubalulekile ekugcineni ubuqotho besistimu nokuvimbela ukungcoliswa noma ukulimala. Ama-valve okuhlola ama-Swing, ane-disk yawo ene-hinged evulekayo lapho amanzi egeleza ngendlela efanele, avame ukusetshenziswa ezinhlelweni zokuvikela umlilo ngenxa yokwethembeka nokuklama kwawo okulula.
3. Ama-Ball Valves
Amavalvu ebhola asebenzisa idiski eyindilinga ("ibhola") ukulawula ukugeleza kwamanzi. Lapho imbobo yebhola ihambisana nesiqondiso sokugeleza, i-valve ivuliwe, futhi lapho ibhola lizungeza ama-degree angu-90, i-valve ivaliwe. Ama-valve ebhola ayaziwa ngokuqina kwawo kanye nekhono elihle lokuvala, okuwenza alungele izimo zokuvala izimo eziphuthumayo. Zivame ukusetshenziswa emapayipini amancane obubanzi ngaphakathi kwezinhlelo zokuvikela umlilo futhi zihlonishwa ngokusebenza kwazo okusheshayo nokuthembeka.
4. Ama-Butterfly Valves
Amavalvu ovemvane angolunye uhlobo lwevalvu yekota esebenzisa idiski ejikelezayo ukuze ilawule ukugeleza. Zidume kakhulu ezinhlelweni zamapayipi ezinobubanzi obukhulu ngenxa yokwakheka kwazo okuhlangene kanye nokusebenza kalula. Amavalve ovemvane ngokuvamile alula futhi angabizi kakhulu kunamavalvu esango noma embulunga, okuwenza abe inketho engabizi kakhulu yokulawula ukugeleza kwamanzi ezinhlelweni zokulwa nomlilo. Avame ukusetshenziswa njengama-valve ahlukanisayo ezinhlelweni zokufafaza umlilo, lapho izithiyo zesikhala nezindleko zicatshangelwa.
Isiphetho
Uhlobo ngalunye lwe-valve ohlelweni lokulwa nomlilo lufeza injongo ethile, lubambe iqhaza ekuphepheni okuphelele nokusebenza kahle kwesistimu. Ukuqonda izindima nokusebenza kwalawa mavalvu kungasiza ekwakhiweni okufanele, ekukhethweni nasekugcinweni kwezinhlelo zokuvikela umlilo. Ngokuqinisekisa ukuthi ama-valve afanele asetshenziswa futhi agcinwe ngendlela efanele, umuntu angathuthukisa ngokuphawulekayo ukusebenza kahle kwesistimu yokucisha umlilo, ekugcineni avikele izimpilo nempahla emiphumeleni ebhubhisayo yomlilo.
