Liphaephe tsa ho kenya metsi le tsa makeup bakeng sa lisebelisoa (tse kang hitara, cooling tower, joalo-joalo) 10. Lipeipi tsa phano bakeng sa lisebelisoa tsa bohloeki (tse kang tse kholo, meroto, likotlolo tsa ho hlatsoa, ​​lishaoara, joalo-joalo). 11. Lisebelisuoa tse ling, tse kang valve ea ho qeta ka mokhoa o itekanetseng, valve ea khatello ea khatello, metsi a hammer eliminator, gauge ea khatello, sprinkler, joalo-joalo, valve e fokotsang khatello le thibelo ea ho khutlela morao, joalo-joalo 12. Karolo e tlaase ka ho fetisisa ea marang-rang ea phepelo ea metsi e lokela ho hlomelloa ka ho lokolloa ha metsi. valve (3) Ka kakaretso, valve ea ho hlahloba e tla khethoa ho ea ka boemo ba ho kenya, khatello ea metsi ka pel'a valve, litlhoko tsa ts'ebetso ea ho tiisa ka mor'a ho koala le boholo ba hamore ea metsi e bakoang ke ho koala 1. Ha khatello ea metsi e le ka pel'a valve, swing. , li-valve tsa ho hlahloba bolo le li-shuttle li lokela ho khethoa 2. Ha ts'ebetso ea ho tiisa ka mor'a ho koala e le thata, ho eletsoa ho khetha valve ea ho hlahloba ka selemo sa ho koala 3. Ha ho hlokahala ho fokolisa hamore ea metsi e koalang, ho eletsoa ho khetha Ho koala ka potlako ho koala valve ea ho hlahloba kapa ho koala butle-butle ka sesebelisoa sa damping 4. Sekhahla sa valve kapa mokokotlo oa valve oa ho hlahloba o tla khona ho koala ka boeona tlas'a ts'ebetso ea matla a khoheli kapa a selemo (4) Li-valve tsa ho hlahloba li tla fanoa holim'a likarolo tse latelang tsa lipeipi tsa phepelo ea metsi: Peiping e kenang; ho futhumatsa metsi a koetsoeng kapa thepa ea metsi; holim'a phala ea pompo ea metsi; phaepheng ea ho tsoa ea tanka ea metsi, tora ea metsi le letamo la lihlabeng moo metsi a kenang le lipeipi tsa ho tsoa li arolelana phala e le 'ngoe. Tlhokomeliso: karolo ea phala e nang le thibelo ea ho phalla ha pipe ha e hloke ho kenya valve ea ho hlahloba.
