Ivalve yebhabhathane enye eccentric
Ukuze kulungiswe ingxaki ye-extrusion phakathi kwediski kunye nesihlalo sevalve yevalve yebhabhathane egxininisekileyo, iveliswa ivalve yebhabhathane eccentric. Ukusasaza kwaye unciphise ukukhutshwa okugqithisileyo kweziphelo eziphezulu kunye nezisezantsi zeplate yebhabhathane kunye nesihlalo sevalve. Nangona kunjalo, ngenxa yesakhiwo esisodwa se-eccentric, i-scraping phenomenon phakathi kwe-disc kunye nesihlalo se-valve ayinyamalala ngexesha lonke lokuvula kunye nokuvala inkqubo ye-valve, kwaye uluhlu lwesicelo lufana nolo lwe-valve ye-butterfly edibeneyo, ngoko ayisetyenziswanga kakhulu.
Ivalve yebhabhathane ene-eccentric ephindwe kabini
Kwisiseko sevalve yebhabhathane eccentric, kunjalo ivalve yebhabhathane eccentric kabini esetyenziswa kakhulu ngoku. Isici sayo sesakhiwo kukuba i-shaft center ye-valve stem iyaphambuka kumbindi we-disc kunye nombindi womzimba. Impembelelo ye-eccentricity ephindwe kabini yenza ukuba i-disc ihlukane nesihlalo se-valve ngokukhawuleza emva kokuba i-valve ivuliwe, ephelisa kakhulu ukugqithiswa okungafunekiyo kunye nokukrazula phakathi kwe-disc kunye nesihlalo se-valve, ukunciphisa ukuchasana kokuvula, ukunciphisa ukunxiba, kunye nokuphucula ubomi beSitulo. Ukukhuhla kuncitshiswe kakhulu, kwaye kwangaxeshanye,ivalve yebhabhathane eccentric kabini inokusebenzisa isihlalo sevalve yentsimbi, ephucula ukusetyenziswa kwevalve yebhabhathane kwindawo yobushushu obuphezulu. Nangona kunjalo, ngenxa yokuba umgaqo wayo wokutywina usisiseko sokutywinwa kwesigxina, oko kukuthi, indawo yokutywina yediski kunye nesihlalo sevalve ihambelana nomgca, kunye nokuguqulwa kwe-elastic okubangelwa yi-disc extrusion yesihlalo sevalve kuvelisa umphumo wokutywina, ngoko ke ineemfuno eziphezulu zokuvala indawo (ingakumbi isihlalo seValve yentsimbi), i-low pressure ephethe umthamo, yiyo loo nto ngokuqhelekileyo abantu be-valve bacinga ukuba i-valve ephezulu ayinayo i-butterfant.
Ivalve yebhabhathane eccentric kathathu
Ukumelana nokushisa okuphezulu, isitywina esinzima kufuneka sisetyenziswe, kodwa inani lokuvuza likhulu; ukuya ku-zero ukuvuza, itywina elithambileyo kufuneka lisetyenziswe, kodwa alimelani nobushushu obuphezulu. Ukoyisa ukuchasana kwevalve yebhabhathane ephindwe kabini, ivalve yebhabhathane ibiyeyona ndawo iphambili okwesithathu. Isici sayo sesakhiwo kukuba ngelixa i-valve ye-eccentric ephindwe kabini i-eccentric, i-conical axis ye-disc yokutywinwa kwendawo yokutywina ithotywe kwi-cylinder axis yomzimba, oko kukuthi, emva kwe-eccentricity yesithathu, icandelo lokutywinwa kwediski alitshintshi. Ke isangqa sokwenyani, kodwa i-ellipse, kwaye imilo yendawo yokutywina nayo i-asymmetrical, elinye icala lithambekele kumgca ophakathi womzimba, kwaye elinye icala lihambelana nomgca ophakathi womzimba. Uphawu lwesi sigxina sesithathu kukuba isakhiwo sokutywina sitshintshiwe ngokusisiseko, ayisesiso isitywina, kodwa isitywina se-torsion, oko kukuthi, ayithembeli kwi-deformation ye-elastic yesihlalo sevalvu, kodwa ixhomekeke ngokupheleleyo kuxinzelelo lomphezulu woqhagamshelwano wesihlalo sevalve ukufezekisa umphumo wokutywina, ngoko ke, ingxaki ye-zero yokuvuza i-valve yokudibanisa kunye ne-valve yokudibanisa i-valve ewileyo, i-valve yawela phezu kwentsimbi. ngokulinganayo noxinzelelo oluphakathi, uxinzelelo oluphezulu kunye nokumelana nobushushu obuphezulu buyasonjululwa ngokulula.
