Izinhlelo zokucisha izicishamlilo zibalulekile ekuvikeleni izimpilo kanye nempahla ngokumelene nezingozi zomlilo. Ingxenye ebucayi yalezi zinhlelo yinqwaba yama-valve asetshenziselwa ukulawula, ukulawula, nokuhamba ngokuqondile kokugeleza kwamanzi. Ukuqonda izinhlobo ezahlukahlukene zama-valves kanye nezindima zazo ngaphakathi kohlelo lokuvikela umlilo kubalulekile ekuklameni nokulungiswa. Ngezansi, sizohlola amanye ama-valve ajwayelekile asetshenziswa ezinhlelweni zokulwa nomlilo.
1. Ama-gang valves
Ama-Valves wesango aphakathi kwezindlela ezisetshenziswa kakhulu ezinhlelweni zokuvikela umlilo. Lawa ma-valves asebenza ngokuphakamisa isango (i-disc eyisicaba noma ye-wedge ebunjiwe) ngaphandle kwendlela yokugeleza kwamanzi. Uma kuvulwa ngokuphelele, ama-varo valves avumela ukugeleza kwamanzi okungahleliwe, okwenza kube yinto efanelekile ngezigaba ezihlukanisayo zenethiwekhi yokuvikela umlilo. Ngokuvamile asetshenziswa kuzinhlelo zokusebenza lapho i-valve ivulekile ngokuphelele noma ivalwe ngokuphelele. Ama-Valves wesango, ikakhulukazi lezo ezine-OS & Y (ngaphandle kwesikulufu kanye nejoka), zikhethwa ngoba isimo sazo esivulekile noma esivaliwe singanqunywa kalula ngesikhundla sesikulufa nejoka.
2. Bheka ama-valves
Bheka ama-valves abalulekile ukuvimbela ukubuyela emuva kwezinhlelo zokulwa nomlilo. Bavumela amanzi ukuthi ageleze endaweni eyodwa kuphela, ukuvala ngokuzenzakalelayo uma ukugeleza kubuyela emuva. Lo msebenzi ubalulekile ekugcineni ubuqotho besistimu nokuvimbela ukungcoliswa noma ukulimala. Swing Hlola ama-valves, ngediski yawo ebihilelekile evulekile lapho amanzi egeleza ngendlela efanele, asetshenziswa kakhulu ezinhlelweni zokuvikela umlilo ngenxa yokwethenjwa kwawo kanye nokwakhiwa kwawo okulula.
3. Ama-valve ebhola
Ama-Valves webhola asebenzisa i-disc eyi-spherical ("ibhola") ukulawula ukuhamba kwamanzi. Lapho umgodi webhola uqondaniswe nendlela yokugeleza, i-valve ivulekile, futhi lapho ibhola lijikeleza ama-degree angama-90, i-valve ivaliwe. Ama-valves webhola ayaziwa ngokuqina kwawo kanye namakhono aphezulu okubekwa uphawu, okwenza balungele izimo eziphuthumayo eziphuthumayo. Imvamisa isetshenziswa ngamapayipi amancane abubanzi ngaphakathi kwezinhlelo zokuvikela umlilo futhi zibhekwa ukusebenza kwazo okusheshayo nokwethembeka.
4. Ama-butterfly valves
Ama-butterfly valves angenye uhlobo lwe-valve yekota esebenzisa idiski elijikelezayo ukulawula ukuhamba. Zithandwa kakhulu ezinhlelweni zamapayipi ezinkulu zamapayipi ngenxa yokwakhiwa kwawo okuhlangene kanye nokusebenza kalula. Ama-butterfly valves ngokuvamile alula futhi abiza kakhulu kunama-sango noma ama-valves omhlaba, abelwenza inketho engabizi kakhulu yokulawula ukugeleza kwamanzi ezinhlelweni zokulwa nomlilo. Imvamisa isetshenziswa njengama-valves okuzihlukanisayo ezinhlelweni zokufakelwa komlilo, lapho izingqinamba zesikhala nezindleko kucatshangelwa khona.
Ukugcina
Uhlobo ngalunye lwe-valve ohlelweni lokulwa nomlilo lusebenza ngenhloso ethile, okufaka isandla ekuphepheni okuphelele kanye nokusebenza kahle kohlelo. Ukuqonda izindima kanye nokusebenza kwalezi zivawu kungasiza ekuklameni okufanele, ukukhethwa, kanye nokunakekelwa kwezinhlelo zokuvikela umlilo. Ngokuqinisekisa ukuthi ama-valve afanele asetshenziswa futhi agcinwe kahle, umuntu angakhulisa kakhulu ukusebenza kahle kohlelo lokucisha umlilo, ukuvikela izimpilo kanye nempahla emiphumeleni emibi yomlilo.
