Ivalvu yesango lommese yangena eShayina ngawo-1980. Eminyakeni engaphansi kwengu-20, ububanzi bokusetshenziswa kwayo buye banda kusukela emikhakheni evamile kuya ezinhlobonhlobo zezimboni, kusukela ekulungisweni kwamalahle, ekukhishweni kwe-gangue kanye nokukhishwa kwe-slag ezitshalweni zamandla ezimayini kuya ekuhlanzweni kwendle yasemadolobheni, kusukela ekuthuthukisweni kwamapayipi ezimbonini ajwayelekile kuya ezinhlelweni zamapayipi zobungcweti ezifana nokudla, impilo kanye nemithi.
Izindlela zokushayela ze-valve yesango lommese yilezi:
Izindlela zokushayela ezenziwe ngesandla, zikagesi, zomoya, ze-hydraulic, ze-bevel, ze-electro-hydraulic kanye ne-pneumatic kanye neze-hydraulic. Isimo se-valve yesango lommese: isiqu esikhuphukayo kanye nesiqu esingakhuphukayo. Izinto ze-valve yesango lommese: insimbi ephothiweyo, insimbi ephothiweyo, insimbi yekhabhoni, insimbi engagqwali, ulwelwesi lwe-fluorine, njll. I-valve yesango lommese: uphawu oluqinile, uphawu oluthambile, uphawu oluhlangothini olulodwa, uphawu oluhlangothini oluphindwe kabili nezinye izinto.
Indlela efanele yokufaka iyisisekelo sokusebenza kahle komshini. I-valve yesango lommese isebenzisa ubunjiniyela bokuqinisa njengento eyinhloko yokukhuhla ngokuvala kanye nokukhuhla ngokuvimbela ukugoba. Ngesikhathi esifanayo, yakhelwe ngesimo sesakhiwo sokukhuhla ngokuvimbela ukugoba. Inomsebenzi ophindwe kabili wokukhuhla ngokuvala noma ukuvala + ukugoba, futhi impilo yayo yesevisi ingafinyelela izikhathi eziphindwe kayishumi kune-valve yesango lensimbi evamile.
Ngezinzuzo zomthamo omncane, ukumelana nokugeleza okuncane, isisindo esincane, ukufakwa okulula nokuqaqwa, ivalvu encane yesango lommese ixazulula izinkinga ezinzima zokumelana nokugeleza okukhulu, isisindo esinzima, ukufakwa okunzima kanye nendawo enkulu yephansi yevalvu evamile yesango, ivalvu yesango eliyisicaba, ivalvu yebhola, ivalvu yokuma, ivalvu yokulawula kanye nevalvu yebhabhathane. Ngemva kokuvela kwevalvu yesango lommese, inani elikhulu lamavalvu ajwayelekile okusika kanye namavalvu okulawula ashintshiwe. Namuhla, inani elikhulu levalvu yesango lommese lisetshenziswa e-United States naseJapan.
