Balofo ea bololihlahisoa li fetohile ho tloha mokokong oa mokoko, valve ea bolo ke sebaka sohle e le likarolo tse bulang le tse koalang (spool), li sebelisa sebaka se pota-potileng axis ea valve stem rotation 90 degrees ho finyella sepheo sa ho bula le ho koala valve. Balofo ea bolo e sebelisoa haholo ho khaola, ho aba le ho fetola tsela ea phallo e mahareng phaepheng. Valve ea bolo e nang le spool e bulehileng ea sebopeho sa V le eona e na le ts'ebetso e ntle ea taolo ea phallo.
Li-valve tsa bolo ha li bonolo feela ka sebopeho le ts'ebetso e ntle ea ho tiisa, empa hape li nyane ka boholo, boima bo bobebe, bo tlase ts'ebelisong ea lisebelisoa tse tala, boholo bo nyane ba ho kenya, bo nyane ka nako ea ho khanna, ts'ebetso e bonolo ebile ho bonolo ho e hlokomela le ho bula kapele. ho koala. Ke e 'ngoe ea mefuta ea li-valve tse ntseng li hola ka potlako lilemong tse mashome tsa morao tjena. Tšebeliso ea li-valve tsa bolo e pharaletseng haholo. Mefuta e fapa-fapaneng le bongata ba li-valve tsa bolo li ntse li eketseha. Li ntse li tsoela pele ka lehlakoreng la mocheso o phahameng, khatello e phahameng, orifice e kholo, sealability e phahameng, bophelo bo bolelele ba tšebeletso, ts'ebetso e ntle ea taolo le mesebetsi e mengata. Li-index tsa bona tse ts'epahalang le tse ling tsa ts'ebetso li fihlile maemong a holimo, 'me li nkile sebaka sa tšebeliso ea li-valve tsa heke, li-valve tsa globe le li-valve tsa throttle. Ka ntshetsopele e tswelang pele ya thekenoloji ya valve valve, e tla sebediswa ka bophara nakong e kgutshwane e lebellwang, haholoholo diphaepheng tsa oli le kgase, diyuniti tse hlwekisang oli le indastering ya nyutlelie. Ntle le moo, liindastering tse ling tsa maemo a maholo le a mahareng, a mahareng le a tlase a khatello, li-valve tsa bolo le tsona e tla ba e 'ngoe ea mefuta e meholo ea li-valve.
Ho nepahala ha ts'ebetso e phahameng, litšenyehelo tse phahameng, mocheso o phahameng ha o bonolo ho o sebelisa, joalo ka litšila tse ka har'a liphaephe, ho bonolo ho kenngoa ke litšila, tse lebisang ho valve e ke keng ea buleha.
Li-valve tsa bolo li arotsoe ka ts'ebetso:
1. Li-valve tsa Bypass: li-valve tsa bolo li atisa ho buloa metsing a tsitsitseng, kahoo li-valve tsa Bypass li lokela ho kenngoa pele, ke hore mahlakore ka bobeli a tletse metsi.
2. Sephahla sa moea: Ha u tlatsa metsi, moea oa tlosoa 'me buoy e koala valve ka boeona; ha e ntša metsi, buoy e oela ka boeona ka moea oa tlatsetso.
3. Sephahla sa khatello ea khatello: ha u bula le ho koala valve, ntša metsi a khatello pakeng tsa valve le sekoahelo sa ho tiisa ho qoba ho apara sekoahelo sa ho tiisa.
4. Valve ea ho ntša metsi a likhoerekhoere: ho ntša metsi a likhoerekhoere ho tloha karolong e ka tlaase ea khetla ea spherical. Ho kenya le ho hlokomela li-valve tsa bolo ho lokela ho ela hloko lintlha tse latelang:
⑴Boloka sebaka se potolohang sa sephethephethe sa valve.
⑵ E ke ke ea sebelisoa joalo ka moferefere.
⑶ Li-valve tsa bolo ea mochini oa ho khanna lebanta li ka aroloa ka:
① Li-valve tsa bolo ea moea.
②Belofo ea bolo ea motlakase.
③Belofo ea bolo ea Hydraulic.
④Pneumatic-hydraulic ball valve.
⑤Electro-hydraulic ball valve.
