Yimiphi umehluko kanye nemisebenzi yevalvu eyodwa engavamile, ephindwe kabili kanye nevalvu kathathu engavamile

I-valve eyodwa yebhabhathane engavamile

Ukuze kuxazululwe inkinga yokukhipha phakathi kwediski kanye nesihlalo sevalvu sevalvu yevelufa yevelufa eqondile, kukhiqizwa ivalvu yevelufa yevelufa eyodwa eqondile. Hlakaza futhi unciphise ukukhipha ngokweqile kweziphetho eziphezulu nezingezansi zepuleti yevelufa kanye nesihlalo sevalvu. Kodwa-ke, ngenxa yesakhiwo esisodwa esingavamile, into yokuklwebheka phakathi kwediski nesihlalo sevalvu ayinyamalali phakathi nenqubo yonke yokuvula nokuvala kwevalvu, futhi ububanzi bokusetshenziswa bufana nobevalvu yevelufa yevelufa eqondile, ngakho ayisetshenziswa kakhulu.

Ivalvu yebhabhathane ephindwe kabili

Ngokusekelwe ku-valve eyodwa yebhabhathane engavamile, ivalvu yebhabhathane eliyindilinga eliphindwe kabili lokho okusetshenziswa kabanzi njengamanje. Isici salo sokwakheka ukuthi isikhungo somshafu wesiqu se-valve siyaphambuka enkabeni yediski kanye nesikhungo somzimba. Umphumela wokungaguquguquki okuphindwe kabili wenza idiski ikwazi ukuhlukana nesihlalo se-valve ngokushesha ngemva kokuvulwa kwe-valve, okususa kakhulu ukukhishwa okungadingekile nokuklwebheka phakathi kwediski nesihlalo se-valve, kunciphisa ukumelana kokuvulwa, kunciphisa ukuguguleka, futhi kuthuthukise impilo yeSihlalo. Ukuklwebheka kuncishisiwe kakhulu, futhi ngesikhathi esifanayo,ivalvu yebhabhathane eliyindilinga eliphindwe kabili ingasebenzisa nesihlalo se-valve yensimbi, esithuthukisa ukusetshenziswa kwe-valve ye-butterfly ensimini yokushisa okuphezulu. Kodwa-ke, ngoba isimiso sayo sokuvala siyisakhiwo sokuvala sendawo, okungukuthi, indawo yokuvala yediski kanye nesihlalo se-valve ixhumene emgqeni, futhi ukuguqulwa kwe-elastic okubangelwa ukuphuma kwediski kwesihlalo se-valve kukhiqiza umphumela wokuvala, ngakho-ke inezidingo eziphezulu zesikhundla sokuvala (ikakhulukazi isihlalo se-Valve sensimbi), umthamo wokuthwala umfutho ophansi, yingakho abantu becabanga ukuthi ama-valve e-butterfly awamelani nomfutho ophezulu futhi anokuvuza okukhulu.

Ivalvu yebhabhathane eliyi-eccentric kathathu

Ukuze kumelwane nokushisa okuphezulu, kumele kusetshenziswe uphawu oluqinile, kodwa inani lokuvuza likhulu; ukuze kungabe kusaba khona ukuvuza, kumele kusetshenziswe uphawu oluthambile, kodwa alumelani nokushisa okuphezulu. Ukuze kunqotshwe ukuphikisana kwevalvu yebhabhathane ephindwe kabili, ivalvu yebhabhathane yayingavamile okwesithathu. Isici sayo sokwakheka ukuthi ngenkathi isiqu sevalvu ephindwe kabili singavamile, i-axis eyindilinga yendawo yokuvala idiski ithambekele ku-axis yesilinda yomzimba, okungukuthi, ngemva kokungafani okwesithathu, ingxenye yokuvala idiski ayishintshi. Bese kuba yindilinga yangempela, kodwa i-ellipse, futhi ukuma kwendawo yayo yokuvala nakho akulingani, uhlangothi olulodwa luthambekele emgqeni ophakathi womzimba, kanti olunye uhlangothi luhambisana nomugqa ophakathi womzimba. Isici salokhu kungezwani kwesithathu ukuthi isakhiwo sokuvala sishintshile ngokuyisisekelo, asiseyona uphawu lwesikhundla, kodwa uphawu lokugoba, okungukuthi, asinciki ekuguqukeni kwe-elastic kwesihlalo se-valve, kodwa sinciki ngokuphelele ekucindezelweni kobuso bokuxhumana besihlalo se-valve ukuze kufezwe umphumela wokuvala. Ngakho-ke, inkinga yokuvuza okungenalutho kwesihlalo se-valve yensimbi ixazululwa ngokuwa okukodwa, futhi ngenxa yokuthi ingcindezi yobuso bokuxhumana ilingana nengcindezi ephakathi, ingcindezi ephezulu kanye nokumelana nokushisa okuphezulu nakho kuxazululwa kalula.
