hore re utloisisa litlhaloso tsa li-valve tsa heke le li-valve tsa serurubele,tlohella's hlahisa phapang pakeng tsa li-valve tsa heke le li-valve tsa serurubele:
1. Liphapang tsa bokhoni ba liatleletiki
Tlhalosong e ka holimo, re utloisisa phapang ea tataiso le mokhoa oa ho tsamaea ha li-valve tsa heke le li-valve tsa serurubele.Ho phaella moo, li-valve tsa heke li ka buleha ka ho feletseng le ho koaloa ka ho feletseng, kahoo ha li bulehile ka ho feletseng, ho hanyetsa ho phalla ha li-valve tsa heke ho nyenyane;Li-valve tsa serurubele Boemong bo bulehileng ka ho feletseng, botenya ba valve ea serurubele bo baka khanyetso ho sebaka se phallang.Ho phaella moo, valve ea heke e na le bophahamo bo phahameng ba ho bula, kahoo lebelo la ho bula le ho koala le lieha;ha valve ea serurubele e ka buloa le ho koaloa ka ho potoloha 90 ° feela, kahoo lebelo la ho bula le ho koala le potlakile.
2. Phapang mesebetsing le ts'ebelisong
Li-valve tsa heke li na le ts'ebetso e ntle ea ho tiisa, kahoo hangata li sebelisoa liphaepheng tse hlokang ho tiisoa ka thata 'me ha ho hlokahale hore li buloe le ho koaloa khafetsa ho khaola mokhoa oa ho potoloha.Sephahla sa heke se ke ke sa sebelisoa ho laola phallo.Ho phaella moo, hobane lebelo la ho bula le ho koala ha valve ea heke le lieha, ha lea lokela liphaephe tse hlokang ho koala ha tšohanyetso.Tšebeliso ea li-valve tsa serurubele e batla e pharaletse.Li-valve tsa butterfly li ke ke tsa sebelisoa feela bakeng sa ho khaola, empa hape li na le mosebetsi oa ho fetola sekhahla sa phallo.Ho phaella moo, valve ea serurubele ea buleha le ho koala kapele 'me e ka boela ea buloa le ho koaloa khafetsa.E loketse ka ho khetheha bakeng sa ho sebelisoa maemong a hlokang ho bula kapa ho koala kapele.
Li-valve tsa serurubele li nyane ka boholo 'me boima ba tsona bo bobebe ho feta li-valve tsa heke, ka hona, libakeng tse ling tse nang le sebaka se lekanyelitsoeng sa ho kenya, ho khothalletsoa ho sebelisa serurubele se bolokang sebaka.Har'a li-valve tsa bophara bo boholo, li-valve tsa serurubele ke tsona tse sebelisoang ka ho fetisisa.Li-valve tsa serurubele li boetse li khothaletsoa ho tsamaisa liphaephe tsa media tse nang le litšila tse nyane.
Mabapi le khetho ea li-valve tlas'a maemo a mangata a sebetsang, li-valve tsa serurubele butle-butle li nkile sebaka sa mefuta e meng ea li-valve 'me e fetoha khetho ea pele ho basebelisi ba bangata.
3. Phapang ka theko
Tlas'a khatello e tšoanang le caliber, theko ea valve ea heke e phahame ho feta ea serurubele.Leha ho le joalo, bophara ba li-valve tsa serurubele bo ka ba boholo haholo, 'me theko ea li-valve tsa serurubele tse bophara bo boholo ha e theko e tlaase ho feta li-valve tsa heke.
