Imishini yokukhiya i-valve yesango iyithuluzi lokuphepha elibalulekile kunoma iyiphi indawo yokusebenza lapho kudingeka khona ukuhlukaniswa kwe-valve.Lezi zisetshenziswa, ezaziwa nangokuthii-valve LOTO (ukukhiya/ukuphuma), zenzelwe ukuvimbela ukusebenza ngengozi noma okungagunyaziwe kwamavalvu esango, ukuqinisekisa ukuphepha kwabasebenzi kanye nobuqotho bemishini.
Imishini yokukhiya i-valve yesangoasetshenziswa kakhulu ezimbonini ezifana nowoyela negesi, amakhemikhali, ukukhiqiza kanye nezinsiza lapho ama-valve adinga ukuhlukaniswa ukuze alungiswe, alungiswe noma eminye imisebenzi.Lawa madivaysi asebenziseka kalula futhi asebenza kahle kakhulu ekuvimbeleni ukukhululwa kwezinto eziyingozi, ukulahlekelwa ingcindezi, noma ukulimala okungenzeka kwemishini.
Esinye sezici eziyinhloko zeImishini yokukhiya i-valve yesangoukuguquguquka kwazo.Atholakala ngosayizi abahlukahlukene ukuze athwale izinhlobo ezahlukene zamavalvu esango, okuhlanganisa ama-handwheel asebenza ngesondo, ama-chain-operated valves, nama-valve asebenza ngamasondo.Lokhu kuqinisekisa ukuthi zingasetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, okuzenza zibe utshalomali olubalulekile kunoma iyiphi inhlangano.
Ngaphezu kokuhlukahluka,Imishini yokukhiya i-valve yesangoaklanywe ngokuqina nokwethembeka engqondweni.Zenziwe ngezinto ezisezingeni eliphezulu, ezinjengama-polymer aqinile we-thermoplastic, okuqinisekisa ukuthi angakwazi ukumelana nezimo ezinzima zezindawo zezimboni.Lokhu kusho ukuthi bangahlinzeka ngokuhlukaniswa kwama-valve okusebenzayo iminyaka ezayo ngaphandle kwesidingo sokushintshwa njalo.
Ngaphezu kwalokho, i-idivayisi yokuvala i-valve yesangoyakhelwe ukuthi ifakwe kalula futhi isuswe ukuze isetshenziswe ngendlela efanele futhi elula.Aklanywe ngendlela ehlukile ukuthi asetshenziswe ngokushesha nangokuvikelekile kuma-valve, avimbele noma yikuphi ukufinyelela okungagunyaziwe noma ukusebenza.Lokhu kuqinisekisa ukuthi abasebenzi bangakwazi ukuhlukanisa i-valve ngokuzethemba ngaphandle kwengozi yengozi noma isigameko.
Mayelana nokuphepha,Imishini yokukhiya i-valve yesangoziyingxenye ebalulekile yohlelo lweLOTO lwanoma iyiphi inhlangano.Bahlinzeka ngendlela ethembekile nephumelelayo yokuvimbela ukusebenza kwe-valve ngengozi noma okungagunyaziwe, okusiza ukuqinisekisa ukuphepha kwabasebenzi kanye nobuqotho bemishini.Ngokuhlanganisa lawa madivayisi ezinqubweni zabo zokuphepha, izinhlangano zingabonisa ukuzibophezela kwazo ekuvikeleni abasebenzi kanye nokuvimbela izingozi ezingaba khona.
Ngokufigqiwe,Imishini yokukhiya i-valve yesangoziyithuluzi lokuphepha elibalulekile lanoma iyiphi indawo yokusebenza edinga ukuhlukaniswa kwe-valve.Bahlinzeka ngesisombululo esiguquguqukayo, esihlala njalo nesithembekile esivimbela ukusebenza ngengozi noma okungagunyaziwe kwama-valve wamasango, okusiza ukuqinisekisa ukuphepha kwabasebenzi kanye nobuqotho bemishini.Ngokusebenzisa kwawo kalula nokusebenza ngempumelelo, lawa madivayisi awutshalomali olubalulekile kunoma iyiphi inhlangano efuna ukuthuthukisa izinqubo zayo zokuphepha nokuvikela abasebenzi bayo.
