Ivalve yebhabhathane ene-eccentric eqinileyoiphuculwa ngokuthe ngcembe ukusuka kwivalve yebhabhathane eqhelekileyo ukuze iqhelane neemeko zokusebenza ezahlukeneyo (ezifana nobushushu bokusebenza kunye noxinzelelo lokusebenza).Ineenzuzo zesakhiwo esilula, ukutywinwa okuthembekileyo, ukuvulwa kokukhanya, ubomi obude benkonzo kunye nokugcinwa kakuhle.Okwangoku, kunye nophuhliso lwenguqu enkulu yezixhobo zokwenza i-iron e-China, i-valve ye-butterfly eqinile i-double eccentric isetyenziswe ngokubanzi kunikezelo lwamanzi kunye nokukhupha amanzi, ukhuseleko lomlilo, isinyithi kunye nezinye iinkqubo zemibhobho.
UmGaqo wokuSebenza:
Ngokwethiyori, ivalve yebhabhathane eqhelekileyo itywiniwe njengonxibelelwano lomgca.Ngelixa kumanqanaba amaninziivelufa yebhabhathane kabini eccentric yentsimbi eqinileyo, isikhundla sesibini sokutywinwa senza ibhanti lendandatho ebanzi ukusuka kumgca wokuqala ngenxa ye-eccentricity yesibini (indawo ye-valve stem iya phezulu).Logama nje udibaniso lomphezulu lwesibini sokutywina lukweli bhanti leringi, ukutywinwa kunokufezekiswa ngaphandle kweqela elibambayo xa kuvulwa idiski yevalvu.
Ngexesha lokuvulwa kwediski yevalve, iindawo zokutywina zediskhi yevalve yebhabhathane eqhelekileyo zihamba ecaleni kwendlela ethe ngxi yebhasi yesitulo sevalve econayo.Kwaye kukho ukuguqulelwa okuhambelanayo phakathi kwezibini zokutywina.Ke itorque yefriction inkulu.Nangona kunjalo, ukuguqulelwa phakathi kwezibini zokutywinwa kweivelufa yebhabhathane kabini eccentric yentsimbi eqinileyoincinci kakhulu.Kwaye inqaku ngalinye letywina loqhagamshelo lomphezulu lahlulwe ngokukhawuleza ecaleni kwendlela ye-tangent yendlela yebhasi yesitulo sevalve.Ngoko ke, i-torque ye-friction incinci kakhulu, enciphisa ngokufanelekileyo ukunxiba phakathi kweebini zokutywina.
Kwinkqubo yesinyithi, i-valve yebhabhathane ye-eccentric eccentric eqinile isetyenziswa kakhulu kwinkqubo yokufudumeza kunye nenkqubo yokususa uthuli olomileyo lwe-ironmaking blast furnace ene-diameter enkulu yegama, uxinzelelo oluphantsi lokusebenza, ukuvulwa okuphantsi kunye nokuvala uxinzelelo oluhlukeneyo kunye nobushushu obuphezulu (200 ° C. ~ 350°C).
Njengeivalve yebhabhathane eqinileyo etywiniweyo ephindwe kabiniinomsebenzi omhle kakhulu wokutywina, ubushushu obusebenzayo obubanzi, uxinzelelo olukhulu lokusebenza, ukuxhathisa ukunxiba, ukumelana nokudleka kunye nobomi benkonzo ende.Ke ngoko, iindima zayo zinjengevalve yokuvala umoya wokutsha, ivalve yokuvala igesi yokutshisa, indawo yokungena yegesi kunye nevalve yokuvala ivalve yenkqubo yokutshintshiselana ngobushushu, igesi ephumayo kunye nevalve yokuvala ubushushu kunye nokuvalwa kwegesi. -ivalve yenkqubo yokususa uthuli olomileyo.
