Izici zokugeleza kwevalvu zijika futhi zihlukaniswe ngezigaba, ukugeleza kwevalvu ku-valve kuzo zombili izinhlangothi umehluko wokucindezela uhlala unjalo, ukugeleza okuphakathi ngokusebenzisa ukugeleza kwesihlobo sevalvu kanye nokuvulwa kwayo phakathi kobudlelwano phakathi kwezimpawu zokugeleza kwevalvu kuyizinkomba zobuchwepheshe ezibalulekile kanye nemingcele enkambisweni yesicelo sevalvu ukwenza ukukhetha okulungile kunokubaluleka okubaluleke kakhulu.

Isici sokugeleza kwevalvu singachazwa ngokuthi: ukugeleza okuhlobene kwe-medium elawulwayo ngevalvu, kanye nobudlelwano phakathi kokuvulwa okuhlobene (ukuhamba okuhlobene) kwevalvu kanye nevalvu kubizwa ngokuthi isici sokugeleza kwevalvu elawulayo. Ngokuvamile, ihlukaniswe ngezinhlobo ezine: umugqa oqondile, iphesenti elilinganayo (i-logarithm), i-parabola kanye nokuvula okusheshayo! Incazelo ethile kanye nezinzuzo yilezi ezilandelayo:

Okokuqala, isici esiqondile sibhekisela ebudlelwaneni obuqondile phakathi kwesilinganiso sokugeleza kwevalvu kanye nokuvulwa okuhlobene, okungukuthi, ukuguquguquka kokugeleza okubangelwa ushintsho lokuvulwa kweyunithi. Ukuhamba okuhlobene kwezimpawu eziqondile kusebudlelwaneni obuqondile nesilinganiso sokugeleza okuhlobene. Ushintsho lwesilinganiso sokugeleza olubangelwa ushintsho lokushaya kweyunithi luhlala lunjalo. Uma izinga lokugeleza likhulu, inani elihlobene lesilinganiso sokugeleza lishintsha kancane, kanti izinga lokugeleza lincane, inani elihlobene lesilinganiso sokugeleza lishintsha kakhulu.

Okwesibili, isici esilinganayo samaphesenti (i-logarithm) sisho ukuthi ushintsho lokugeleza oluhlobene olubangelwa ushintsho lokuvulwa kweyunithi luhambisana nesilinganiso sokugeleza esihlobene sephuzu, okungukuthi, i-coefficient yokukhulisa ye-valve yokulawula iyashintsha, futhi iyanda ngokukhuphuka kokugeleza okuhlobene. I-stroke ehlobene kanye nokugeleza okuhlobene kwezimpawu ezilinganayo zamaphesenti akulona ubudlelwano obuqondile, futhi ushintsho lokugeleza olubangelwa ushintsho lokugeleza kweyunithi endaweni ngayinye ye-stroke luhambisana nesilinganiso sokugeleza kuleli phuzu, futhi iphesenti loshintsho lokugeleza lilingana. Ngakho-ke, inzuzo yalo ukuthi izinga lokugeleza lincane, ushintsho lokugeleza luncane, futhi lapho ukugeleza kukhulu, izinga lokugeleza lishintsha kakhulu, okungukuthi, linokunemba okufanayo kokulungisa ezindaweni ezahlukene zokuvula.

Okwesithathu, isici se-parabolic sibhekisela ekushintsheni kokugeleza okuhlobene okubangelwa ushintsho lokuvuleka okuhlobene kweyunithi ngokulingana ngqo nomsuka wesikwele wenani lokugeleza elihlobene laleli phuzu. Izinga lokugeleza liyahlukahluka ngokulingana nezinhlangothi ezimbili ze-stroke, ngezici ezicishe zibe phakathi kwezici eziqondile nezilinganayo zamaphesenti.

Okwesine, isici sokugeleza kokuvula okusheshayo sibhekisela ekugelezeni okukhulu lapho ukuvulwa kuncane, ngokwanda kokuvulwa, izinga lokugeleza lingasheshe lifinyelele esiphezulu, bese kwandisa ukuvulwa, ushintsho lokugeleza luncane kakhulu, ngakho-ke lubizwa ngokuthi isici sokuvuleka okusheshayo.

Izici zokugeleza kwamavalvu e-diaphragm ziseduze nezici zokuvula okusheshayo, izici zokugeleza kwamavalvu e-butterfly ziseduze nezici ezilinganayo zephesenti, izici zokugeleza kwamavalvu esango ziyizimpawu eziqondile, izici zokugeleza kwamavalvu ebhola ziyimigqa eqondile esigabeni sokuvula nokuvala esiphakathi, kanye nezici ezilinganayo zephesenti ekuvulekeni okuphakathi.

Ngokuvamile, ama-valve ebhola kanyeamavalvu ebhabhathaneNgokuvamile azisetshenziselwa ukulungiswa, uma zisetshenziselwa ukulungiswa, kodwa futhi esimweni sokuvulwa okuncane ukuze kudlale indima ekulawulweni, ngokuvamile zingahlukaniswa njengohlobo lokuvulwa okusheshayo, kanti okwangempela njengokulawulwa kwe-valve enkulu yomhlaba eyisisekelo, ikhanda le-valve elicutshungulwa libe yi-parabolic cone, i-spherical, njll., lizosebenzisa izici ezihlukene zejika, ngokuvamile lisetshenziswa njengokulungiswa, ngokuyisisekelo iphesenti lezici lisetshenziswa kakhulu.
