Li-valve tsa bolo li sebelisetsoa eng?

Li-valve tsa bolo ke likarolo tsa bohlokoa haholo litsamaisong tsa taolo ea mokelikeli, tse tsebahalang ka ho tšepahala ha tsona, ho tenyetseha ha tsona le katleho ea tsona indastering eohle. Ho tloha liphaepheng tsa matlo ho ea ho li-rig tsa oli tse tebileng, li-valve tsena tsa kotara li bapala karolo ea bohlokoa ho laoleng phallo ea metsi, likhase, esita le mecha ea phatlalatso e tiileng. Tataisong ena e felletseng, re tla teba ka hore na li-valve tsa bolo li sebetsa joang, melemo ea tsona ea bohlokoa, lits'ebetso tse tloaelehileng, le mekhoa ea kamoso - ho u hlomella ka tsebo ea ho li khetha le ho li sebelisa ka katleho.

Kamoo Li-valve tsa Ball li Sebetsang Kateng

Bohareng ba tsona, di-valve tsa bolo di sebetsa ka mokhoa o bonolo empa o sebetsa hantle: diski e chitja e potolohang ("bolo") e nang le mokoti o bohareng (lesoba) e laola phallo ea metsi. Tshebetso ea valve e itšetlehile ka likarolo tse tharo tsa bohlokoa: 'mele oa valve (o nang le likarolo tse ka hare le o hokahanang le liphaephe), bolo e nang le masoba (bohareng bo laolang ho buleha le ho koala), le kutu (e fetisang matla a potolohang ho tloha ho actuator ho ea ho bolo).

Ha mokoti wa bolo o tsamaellana le phaephe, valve e bulehile ka botlalo, e leng se dumellang phallo e sa sitisweng. Ho potoloha bolo ka di-degree tse 90 (kotara ya ho reteleha) ho beha karolo e tiileng ya bolo tseleng ya phallo, ho tima phallo ka botlalo. Ho sebetsa e ka ba ka letsoho (ka lever kapa lebili la letsoho) kapa ka boiketsetso (pneumatic, motlakase, kapa hydraulic) bakeng sa taolo e hole kapa e nepahetseng. Meralo e mmedi e tlwaelehileng e ntlafatsa ho tenyetseha: di-valve tsa bolo tse phaphametseng (moo bolo e fetohang hanyane tlasa kgatello ho tiisa) le di-valve tsa bolo tse kentsweng ka trunnion (moo bolo e tshehetswang ke dikutu tse ka hodimo le tse ka tlase bakeng sa tshebediso e phahameng ya kgatello).
