Ivalve yebhabhathane ephindwe kabini yeyokuba i-axis ye-valve stem iyatenxa kumbindi wepleyiti yebhabhathane kunye nombindi womzimba. Ngokwesiseko sokubethelela okuphindiweyo, iperi yokutywina yevalve yebhabhathane ene-eccentric eccentric iguqulwa ibe yi-cone eclined.

Ukuthelekisa ubume:

Zombini i-valve ye-butterfly eccentric ephindwe kabini kunye ne-valve ye-butterfly eccentric eccentric ingenza i-butterfly plate ishiye ngokukhawuleza isihlalo sevalve emva kokuvulwa, ikhuphe kakhulu i-extrusion engaphezulu engafanelekanga kunye nokukhuhla phakathi kwepleyiti yebhabhathane kunye nesihlalo sevalve, ukunciphisa ukuchasana kokuvula, ukunciphisa ukunxiba kunye nokuphucula ubomi benkonzo yesihlalo sevalve.

Uthelekiso lwezinto:

Awona macandelo oxinzelelo oluphambili lwevalve yebhabhathane ene-eccentric yenziwe ngentsimbi ye-ductile, kwaye ezona nxalenye zoxinzelelo ziphambili zevalve yebhabhathane eccentric zenziwe ngentsimbi yokuphosa. Amandla entsimbi ye-ductile kunye nentsimbi yokuphosa iyathelekiswa. Isinyithi seDuctile sinamandla emveliso ephezulu, inamandla asezantsi esivuno se-310mpa, ngelixa amandla emveliso yentsimbi eyi-230MPa kuphela. Kwizicelo ezininzi zikamasipala, ezifana namanzi, amanzi etyuwa, umphunga, njl., ukuxhathisa ukubola kunye nokumelana ne-oxidation yensimbi ye-ductile ingcono kuneyentsimbi. Ngenxa ye-spheroidal graphite microstructure ye-ductile iron, i-ductile iron ingcono kunentsimbi etyhidiweyo ekunciphiseni ukungcangcazela, ngoko ke kulungele ukunciphisa uxinzelelo.

Uthelekiso lwesiphumo sokutywinwa:

Ivalve yebhabhathane ephindwe kabini ithatha isitulo esingqukuva nesidadayo. Phantsi koxinzelelo olulungileyo, ukucocwa okubangelwa kukunyamezelwa komatshini kunye nokuguqulwa kweshafu yevalve kunye nepleyiti yebhabhathane phantsi koxinzelelo oluphakathi kwenza umphezulu ongqukuva wepleyiti yebhabhathane usondele ngakumbi kumphezulu wokutywina wesihlalo sevalve. Ngaphantsi koxinzelelo olubi, isihlalo esidadayo sihamba sisiya kuxinzelelo oluphakathi phantsi koxinzelelo oluphakathi, Buyekeza ngokufanelekileyo ukucocwa okubangelwa kukunyamezela kwe-machining kunye nokuguqulwa kwe-valve shaft kunye ne-butterfly plate phantsi kwesenzo soxinzelelo oluphakathi, ukuze uqonde ukutywinwa okubuyela emva.

Ivalve yebhabhathane emithathu eqinileyo etywinayo ithatha isitulo sevalve echophileyo etyekeleyo kunye nomsesane wokutywina onamanqanaba amaninzi. Ngaphantsi koxinzelelo oluhle, ukucocwa okubangelwa ukunyamezela kwe-machining kunye nokuguqulwa kwe-valve shaft kunye ne-butterfly plate phantsi koxinzelelo oluphakathi kwenza ukuba i-ring-level yokutywina ifane ngokusondeleyo kwindawo yokutywinwa kwesihlalo se-valve, kodwa phantsi koxinzelelo olujikelezayo, i-multi-level sealing ring iya kuba kude kwindawo yokutywinwa kwesihlalo se-valve, Ngaloo ndlela, ukutywinwa kwe-valve akunakufezekiswa.
