Umahluko kunye nokusetyenziswa kwe-eccentric ephindwe kabini kunye ne-triple eccentric butterfly valves

Iivalvu zebhabhathane eccentric ephindwe kabini kunye neevalvu zebhabhathane eziphindwe kathathu zisetyenziswa ngokubanzi iindidi zevalvu kwindawo yoshishino. Zidlala indima ebalulekileyo ekulawuleni ulwelo kwaye zisetyenziswa kwimizi-mveliso eyahlukeneyo efana nepetroleum, imichiza, inkqubo yokutya, kunye nokucocwa kwamanzi. Ukwazi umahluko phakathi kwabo kubalulekile ekukhetheni okuchanekileyo kunye nokusetyenziswa kwevalve efanelekileyo.

Umahluko woyilo lolwakhiwo: Uyilo lwevalve yebhabhathane eccentric ephindwe kabini ibandakanya iishafti ezimbini ze-eccentric, enye ibekwe kumbindi wepleyiti yebhabhathane kwaye enye imi kumda wepleyiti yebhabhathane. Esi sakhiwo senza ukuba i-butterfly plate inciphise ukukhuhlana xa ivula kwaye ivala, ngaloo ndlela inciphisa amandla okusebenza. Ngokwahlukileyo, uyilo lwevalve yebhabhathane ene-eccentric eccentric yongeza i-eccentric shaft yesithathu kwipleyiti yebhabhathane, ukuze ipleyiti yebhabhathane ibe nokwahlulwa ngokupheleleyo kwiringi yesihlalo xa ivaliwe, ngaloo ndlela inciphisa uxinzelelo lokutywina kunye nokuphucula ukusebenza kokutywinwa.

Umahluko kumgaqo wokusebenza: Ivalve yebhabhathane ene-eccentric ephindwe kabini ilawula ukuhamba kolwelo ngokujikelezisa ipleyiti yebhabhathane. Xa ipleyiti yebhabhathane ivulwe ngokupheleleyo, kwenziwa umjelo omkhulu phakathi kwepleyiti yebhabhathane kunye neringi yesihlalo, ukuze ulwelo ludlule kakuhle. Ngokuchasene noko, xa i-butterfly plate ivaliwe, umjelo uya kuvalwa ngokupheleleyo, ukuthintela ukuhamba kwamanzi.

Umgaqo-siseko wokusebenza wevalve yebhabhathane ephindwe kathathu iyafana naleyo yevalve yebhabhathane ephindwe kabini, kodwa ihlengahlengisa indawo yepleyiti yebhabhathane kwi-eccentric shaft yepleyiti yebhabhathane ukuze ikwazi ukurhoxa ngokupheleleyo kwiringi yesihlalo xa ihleli. ivaliwe. Olu luyilo lunokunciphisa ukunxiba kwendawo yokutywina, ukwandisa ubomi benkonzo yevalve, kunye nokuphucula ukusebenza kokutywinwa kunye nokumelana noxinzelelo oluphezulu.Ukwahlukana kwiimeko zesicelo: I-valve ye-butterfly eccentric ephindwe kabini idla ngokusetyenziswa kuxinzelelo oluphakathi kunye oluphantsi kunye nolwelo oluqhelekileyo. lawula izicelo. Isakhiwo sayo esilula kunye nokusebenza okuguquguqukayo kufanelekileyo kwizihlandlo ezifuna ukuvulwa rhoqo kunye nokuvala. Ngokomzekelo, i-valve isoloko isetyenziselwa ukubonelela ngamanzi kunye neenkqubo zokuhambisa amanzi, ukuchithwa kwamanzi kunye neenkqubo zomoya, njl.

Ngokuchaseneyo, ivalve yebhabhathane ene-eccentric eccentric ilungele uxinzelelo oluphezulu kunye neemeko zokusebenza ezinzima. Ngenxa yokusebenza kwayo kakuhle kokutywinwa kunye nokumelana noxinzelelo oluphezulu, isetyenziswa rhoqo kwimimandla yepetroleum, ishishini lemichiza, igesi yendalo kunye nokuveliswa kwamandla obushushu. Ukongeza, i-valve ye-butterfly eccentric kathathu nayo ifanelekile kulawulo lwemithombo yeendaba ezonakalisayo kunye nobushushu obuphezulu beendaba.

Isiphelo: Kukho umahluko ocacileyo phakathi kwevalve yebhabhathane ene-eccentric ephindwe kabini kunye nevalve yebhabhathane ene-eccentric ephindwe kathathu kuyilo lwesakhiwo, imigaqo yokusebenza kunye neemeko zosetyenziso. Iivalvu zebhabhathane ezineeccentric zilungele uxinzelelo oluphakathi kunye noluphantsi kunye nolawulo lolwelo ngokubanzi, ngelixa iivalvu zebhabhathane eziphindwe kathathu zilungele uxinzelelo oluphezulu kunye neemeko zenkonzo eziqatha. Ukukhethwa ngokufanelekileyo kunye nokusetyenziswa kweevalve ezifanelekileyo kubalulekile ukuqinisekisa ukusebenza ngokufanelekileyo kunye nokhuseleko lwenkqubo. Ngoko ke, kwizicelo eziphathekayo, sisigqibo esibaluleke kakhulu ukukhetha uhlobo olufanelekileyo lwevalve ngokweemfuno ezithile kunye neemeko zokusebenza.
