Li-valve tsa bololeli-valve tsa serurubele ke lihlopha tse peli tsa bohlokoa tsa li-valve 'me li sebelisoa haholo.Valve ea bolo e hloka ho tiisoa ka thata ka mocheso o phahameng le khatello e phahameng le ho hanyetsa phallo e tlase.Li-valve tsa butterfly li sebelisoa haholo-holo bakeng sa maemo a sebetsang a nang le khatello e tlaase le litlhoko tse tlaase tsa tiiso.
Hape ho na le lihlopha tse ngata tsa li-valve tsa bolo le li-valve tsa serurubele.Li-valve tsa bolo li ka aroloa ka: li-valve tsa tšepe tse tiisitsoeng ka thata, li-valve tsa bolo tse tiisitsoeng ka bonolo, li-valve tsa bolo tse phaphametseng, li-valve tsa bolo tse tsitsitseng, li-eccentric semi-ball valves, li-valve tse laolang sebopeho sa V, jj.
Belofo ea serurubele e arotsoe ka: belofo e meraro ea eccentric ea serurubele, belofo ea serurubele sa eccentric habeli, belofo ea serurubele e bohareng, belofo e tiisang serurubele e thata, belofo e tiisang serurubele e bonolo.
Li-valve tsa bolo le li-valve tsa serurubele ke li-valve tse sebelisoang hangata.Maemong a mang, ka bobeli li ka sebelisoa ka mokhoa o tloaelehileng, 'me maemong a mang a sebetsang, ho ka sebelisoa e le' ngoe feela ea tsona.Litšobotsi tse fapaneng tsa mefuta ena e 'meli ea li-valve.Re sekaseka ka bokhutšoanyane:
Balofo ea bolo: valve ea mokoko e bile teng, karolo e bulang le e koalang ke sedikadikwe, litšobotsi ke tsena:
1. Ho hanyetsa ho potoloha ho nyenyane.Ha e butsoe ka botlalo, ha ho na likarolo tse thibelang ho phalla ha seaplane ho kanaleng;
2. E ka koaloa ka ho feletseng tlas'a khatello e phahameng le mocheso o phahameng;
3. E ka buloa le ho koaloa kapele;
4. Lemoha khanyetso e phahameng ea ho roala le khanyetso e matla ea kutu ka ho thatafatsa kalafo;
5. Sehlopha sa valve se na le symmetrical, se khonang ho mamella ka katleho khatello ea liphaephe 'me se khona ho sebetsana ka katleho le maemo a phahameng a ho sebetsa.
Butterfly valve: Karolo e bulang le e koalang ke poleiti ea serurubele ea mofuta oa disc, e khetholloang ka:
1. Sebopeho se bonolo, boholo bo nyane le ho kenya habonolo;
2. Coefficient e nyenyane ea ho hanyetsa phallo, ho bula le ho koala ka potlako;
3. E ka sebelisoa bakeng sa li-valve tse kholo tsa bophara;
4. Libaka tse fapaneng tsa ho tiisa li ka sebelisoa libakeng tse sa tšoaneng, ho akarelletsa le powdery le granular media.
Ha ho bapisoa le valve ea bolo, valve ea serurubele e na le ts'ebetso ea ho tiisa hanyenyane, empa har'a li-valve tsa bophara bo boholo, serurubele se na le molemo o ikhethang ho feta valve ea bolo;ha e sebelisoa ho fetola sekhahla sa phallo, valve ea serurubele e na le sebaka se senyenyane sa ho fetola, ha V-mofuta oa V-valve o fetoha.Liphaepheng tsa khatello e phahameng, li-valve tsa bolo li na le melemo ho feta li-valve tsa serurubele.
