Ivalvu yebhabhathane enye engaqhelekanga
Ukuze kusonjululwe ingxaki yokukhupha amanzi phakathi kwediski kunye nesihlalo sevalvu yevalvu yebhabhathane engqindilili, ivelufa yebhabhathane enye engqindilili iveliswa. Hlakaza kwaye unciphise ukuphuma kwamanzi okugqithisileyo kweziphelo eziphezulu nezisezantsi zepleyiti yebhabhathane kunye nesihlalo sevalvu. Nangona kunjalo, ngenxa yesakhiwo esinye esingqindilili, into yokukrwela phakathi kwediski kunye nesihlalo sevalvu ayinyamalali ngexesha lonke lenkqubo yokuvula nokuvala kwevalvu, kwaye uluhlu lwesicelo lufana nolwevalvu yebhabhathane engqindilili, ngoko ke ayisetyenziswa kakhulu.
Ivalvu yebhabhathane engaqhelekanga kabini
Ngokusekelwe kwivalvu yebhabhathane enye engaqhelekanga, yiyo ivalvu yebhabhathane engaqhelekanga kabini nto leyo isetyenziswa kakhulu okwangoku. Uphawu lwayo lolwakhiwo kukuba iziko le-shaft yesiqu se-valve liyaphambuka embindini wediski nakwiziko lomzimba. Isiphumo sokungangqinelani kabini senza idiski ikwazi ukuqhekeka kwisihlalo se-valve emva kokuba i-valve ivuliwe, nto leyo ephelisa kakhulu ukukhupha okungafunekiyo nokukrwela phakathi kwediski nesihlalo se-valve, inciphisa ukumelana nokuvulwa, inciphisa ukuguguleka, kwaye iphucula ubomi beSihlalo. Ukukrwela kuncitshisiwe kakhulu, kwaye kwangaxeshanye,ivalvu yebhabhathane engaqhelekanga kabini Ingasebenzisa nesihlalo sevalvu yesinyithi, esiphucula ukusetyenziswa kwevalvu yebhabhathane kwindawo yobushushu obuphezulu. Nangona kunjalo, kuba umgaqo wayo wokutywina sisakhiwo sokutywina sendawo, oko kukuthi, umphezulu wokutywina wediski kunye nesihlalo sevalvu unxibelelene, kwaye ukuguquguquka kwe-elastic okubangelwa kukuphuma kwediski yesihlalo sevalvu kuvelisa isiphumo sokutywina, ngoko ke ineemfuno eziphezulu zesikhundla sokuvala (ingakumbi isihlalo seValve sentsimbi), amandla okuthwala uxinzelelo oluphantsi, yiyo loo nto abantu becinga ukuba iivalvu zebhabhathane azixhathisi kuxinzelelo oluphezulu kwaye zinokuvuza okukhulu.
Ivalvu yebhabhathane engaqhelekanga kathathu
Ukuze kumelwane nobushushu obuphezulu, kufuneka kusetyenziswe isitywina esiqinileyo, kodwa ubungakanani bokuvuza bukhulu; ukuze kungabikho kuvuza, kufuneka kusetyenziswe isitywina esithambileyo, kodwa asimelani nobushushu obuphezulu. Ukuze koyiswe impikiswano yevalvu yebhabhathane ephindwe kabini, ivalvu yebhabhathane yayingaqhelekanga okwesithathu. Uphawu lwayo lolwakhiwo kukuba nangona isiqu sevalvu ephindwe kabini singaqhelekanga, i-axis ekhonkrithi yomphezulu wokutywina idiski ithambekele kwi-axis yesilinda yomzimba, oko kukuthi, emva kokungangqinelani kwesithathu, icandelo lokutywina lediski alitshintshi. Emva koko sisangqa sokwenyani, kodwa yi-ellipse, kwaye imo yomphezulu wayo wokutywina nayo ayilingani, elinye icala lithambekele kumgca ophakathi womzimba, kwaye elinye icala lihambelana nomgca ophakathi womzimba. Uphawu lwale ndlela yesithathu yokungangqinelani kukuba isakhiwo sokutywina sitshintshile ngokusisiseko, asiseyiyo itywina yesikhundla, kodwa yitywina yokutsalwa, oko kukuthi, asixhomekekanga kwi-elastic deformation yesihlalo sevalvu, kodwa sixhomekeke ngokupheleleyo kuxinzelelo lomphezulu woqhagamshelwano lwesihlalo sevalvu ukufezekisa isiphumo sokutywina. Ke ngoko, ingxaki yokuvuza okungavuziyo kwesihlalo sevalvu yesinyithi isonjululwa nge-swoop enye ewileyo, kwaye ngenxa yokuba uxinzelelo lomphezulu woqhagamshelwano luhambelana noxinzelelo oluphakathi, uxinzelelo oluphezulu kunye nokumelana nobushushu obuphezulu nako kusonjululwa ngokulula.
