6 valve ea throttle
Sebopeho sa valve ea throttle ha e le hantle se tšoana le sa valve ea lefats'e ntle le diski ea valve.The valve disc ke karolo ea throttling, 'me libopeho tse fapaneng li na le litšobotsi tse fapaneng.Bophara ba setulo sa valve ha boa lokela ho ba seholo haholo, hobane bophahamo ba ho bula bo nyane.Sekhahla sa phallo e mahareng sea eketseha, ka hona E potlakisa khoholeho ea diski ea valve.The valve throttle e na le litekanyo tse nyane, boima bo bobebe le ts'ebetso e ntle ea phetoho, empa ho nepahala ha phetoho ha ho phahame.
7 valve ea plug
Belofo ea plug e sebelisa 'mele oa plug o nang le lesoba ha karolo e bulang le e koalang,' me 'mele oa plug o potoloha le kutu ea valve ho lemoha ho buleha le ho koala ha valve.Valve ea plug e na le melemo ea sebopeho se bonolo, phetoho e potlakileng, ts'ebetso e bonolo, ho hanyetsa mokelikeli o monyane, likarolo tse fokolang le boima bo bobebe.Ho na le li-valve tsa plug tse otlolohileng, tse tharo le tse 'ne.Sephahla sa plug se otlolohileng se sebelisetsoa ho khaola bohareng, 'me li-valve tsa plug tse litsela tse tharo le tse' nè li sebelisetsoa ho fetola tsela ea bohareng kapa ho arola bohareng.
8 Valofo ea diaphragm
Karolo e bulang le e koalang ea valve ea diaphragm ke diaphragm ea rabara, e pakeng tsa 'mele oa valve le sekoahelo sa valve.Karolo e bohareng e hlahelletseng ea diaphragm e tsitsitsoe holim'a kutu ea valve, 'me setopo sa valve se kentsoe ka rabara.Kaha sehare ha se kene ka hare ho sekoahelo sa valve, kutu ea valve ha e hloke lebokose la ho kenya lintho.Valve ea diaphragm e na le sebopeho se bonolo, ts'ebetso e ntle ea ho tiisa, tlhokomelo e bonolo le ho hanyetsa metsi a manyane.Li-valve tsa diaphragm li arotsoe ka mofuta oa weir, mofuta o otlolohileng, mofuta oa lehlakoreng le letona le mofuta oa phallo e tobileng.
