Inxalenye yokuvula nokuvalwa kweivelufa yesango lomliloyinkunzi yegusha, kwaye ulwalathiso lwentshukumo lwenkunzi yegusha luthe gqolo ukuya kwicala lolwelo. I-valve yesango inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo, kwaye ayikwazi ukulungiswa kunye ne-throttled. Inkunzi yegusha inemigangatho emibini yokutywina. Eyona ndlela ixhaphakileyo yeyokuba iindawo ezimbini zokutywina zevalve yenkunzi yegusha zenza iweji. I-engile ye-wedge iyahluka kunye neeparamitha zevalve, idla ngokuba ngu-50. Xa ubushushu obuphakathi bungekho phezulu, yi-2 ° 52 '. Isango levalve yesango le-wedge linokwenziwa liphelele, elibizwa ngokuba yisango eliqinileyo; Isenokwenziwa kwakhona ibe yinkunzi yegusha enokuvelisa uguquko oluncinci ukuphucula ukuqhubekeka kwayo kwaye yenze ukutenxa kwe-angle yokutywina yomphezulu ngexesha lokulungiswa. Le nkunzi yegusha ibizwa ngokuba yi-elastic ram.
Iindidi zeevalvu zesango lomlilo zinokwahlulwa zibe ziivalve zesango le-wedge kunye neevalvu zesango ezinxuseneyo ngokobume bomphezulu wokutywina. Iivalvu zesango leWedge zinokwahlulwa zibe luhlobo lwesango elinye, uhlobo lweplate yesango eliphindwe kabini kunye nohlobo lwesango elilastiki; Ivalve yesango elinxuseneyo inokwahlulwa ibe yipleyiti yesango enye kunye nepleyiti yesango eliphindwe kabini. Ngokwendawo yomsonto wesiqu sevalve, inokwahlulwa ibe ziindidi ezimbini:ivalve yesango lesiqu esinyukayokwayeIvalve yesango yesiqu enganyukiyo.
Iimpawu zevalve yesango lomlilo:
1. Ubunzima bokukhanya: umzimba wenziwe nge-high-grade nodular black cast iron, kwaye ubunzima bu malunga ne-20% ~ 30% ngaphantsi kwe-valve yesango yendabuko, ekulungele ukufakela nokugcinwa.
Isihlalo sesango esisezantsi esisicaba: emva kokuba ivalve yesango yesiqhelo ihlanjwe ngamanzi, izinto zangaphandle ezifana namatye, iibhloko zokhuni, isamente, iitshiphu zentsimbi kunye nesundries zifakwe kwigroove ezantsi kwevalve, ekulula ukubangela ukuvuza kwamanzi ngenxa ukungakwazi ukuvala ngokuqinileyo. Umzantsi wevalve yesango elitywiniweyo lesihlalo uthatha uyilo olusezantsi oluthe tyaba njengalo lomatshini wombhobho wamanzi, okungekho lula ukubangela ukuba i-sundries idipozithe kwaye yenze ukuba ulwelo luqukuqeleke lungaphazamiseki.
2. I-Integral rubber coating: inkunzi yegusha ithatha irabha ekumgangatho ophezulu kwirabha yangaphakathi nangaphandle. Itekhnoloji yaseYurophu ye-rubber vulcanization yeklasi yokuqala yenza ukuba inkunzi yegusha ivuthwe ukuba iqinisekise imilinganiselo yejometri echanekileyo, kwaye irabha kunye ne-ductile yentsimbi yokuphosa i-RAM idityaniswe ngokuqinileyo, akukho lula ukuwa kwaye ibe nenkumbulo entle elastiki.
3. Umzimba wevalvu yokuphosa ngokuchanekileyo: umzimba wevalvu wenziwe ngokuchaneka kokuphosa, kunye nemilinganiselo yejometri echanekileyo yenza kube lula ukuqinisekisa ukutywinwa kwevalve ngaphandle kokugqiba ngaphakathi komzimba wevalvu.
