Ivalufa yeBhava ephindwe kabini vs iValve yeButterfly ephindwe kathathu?

yintoni umahluko phakathi kwe-eccentric ephindwe kabini kunye ne-triple eccentric butterfly valve?

Kwiivalvu zoshishino, zombini iivalve zebhabhathane eziphindwe kabini kunye neevalvuvu zebhabhathane eziphindwe kathathu zingasetyenziswa kwioyile negesi, kwikhemikhali kunye nonyango lwamanzi, kodwa kunokubakho umahluko omkhulu phakathi kwezi ntlobo zimbini zebhabhathane, ngoko ke kubalulekile ukwazi umahluko. phakathi kwezi ntlobo zimbini zeevalvu ukwenzela ukuba wenze ukhetho olufanelekileyo.

Kweli nqaku, siza kujonga umahluko ophambili phakathiiivalve zebhabhathane kabinikwayeiivalve zebhabhathane eziphindwe kathathungokunjalo nezinto eziluncedo kunye nokusetyenziswa kwazo.

Okokuqala, ukuyila kunye nokwakhiwa kwahlukile.

Idiski yeivalve yebhabhathane eccentric kabiniisusiwe kumgca osembindini womzimba wevalvu kunye ne-shaft.Olu yilo lwe-offset lunceda ukungqubuzana kunye nokunxiba kwesitulo sevalve ethambileyo ngexesha lokuvula nokuvalwa, ngaloo ndlela kwandisa ubomi benkonzo kunye nokuphucula ukutywinwa.Ngelixa into ebizwa ngokuba yi-triple eccentric butterfly valve ine-eccentric yesithathu ngaphezulu kwe-double eccentric, oko kukuthi, yenza imilo yeconical kumphezulu wokutywina, kunye nempahla yendawo yokutywina idla ngokutywinwa kwesinyithi, okukhokelela ekutywinweni okungqongqo kunye nokutywinwa. ukukhuhlana okuncinci, kuyenza ilungele ukusetyenziswa koxinzelelo oluphezulu kunye nobushushu obuphezulu.

Okwesibini, ukusebenza kuyahluka.

Iivalvu zebhabhathane ezithathuzibonelela ngeenzuzo ezininzi ngaphezulu koyilo oluphindwe kabini.Uyilo lwe-eccentric kathathu lubonelela ngesitywina somoya, oku kuthetha ukuba ukuvuza kunokuthintelwa ngokufanelekileyo naphantsi koxinzelelo oluphezulu kunye neemeko zobushushu obuphezulu.Ngoko ke ifaneleke ngakumbi kwizicelo ezibalulekileyo ezifuna ukuvalwa okuqinileyo.Ukongeza, uyilo lwekhowuni ye-eccentric ye-eccentric butterfly cone iphucula ukuxhathisa ukuguga ukuze amaxesha olondolozo anokwandiswa kunye neendleko zokuyigcina zicuthiwe.Ezi zibonelelo zokusebenza zenza ukuba ivalve yebhabhathane ye-eccentric ibe lukhetho lokuqala kwizicelo ezifunwayo kwi-oyile negesi, kwi-petrochemical kunye namashishini okuvelisa amandla.

Ekugqibeleni, i-thIindleko zokwakha azisetyenziswanga.

Inzuzo enkulu yeivalve yebhabhathane eccentric kabinixa kuthelekiswa ne-triple eccentric butterfly valve kukuba ixabiso lokwakha lingaphantsi kancinci.Ukuba iimeko zokusebenza azifuni ubushushu obuphezulu kunye noxinzelelo oluphezulu lwevalve yebhabhathane ephindwe kathathu, ivalve yebhabhathane ephindwe kabini lukhetho olunoqoqosho ngakumbi.Oku kungenxa yokuba iivalve zebhabhathane eccentric zilungele izicelo ezibandakanya uxinzelelo olusezantsi ukuya oluphakathi kunye namaqondo obushushu.Ukusebenza kwabo okuthembekileyo kunye nokusebenza kakuhle kweendleko kubenza babe lukhetho oludumileyo kwizicelo ezahlukeneyo zoshishino.

Ukuqukumbela, ukhetho phakathi kabini kunyeiivalve zebhabhathane eziphindwe kathathukuxhomekeke kwiimfuno ezithile zomphakathi kunye nokusingqongileyo.Iivalve zebhabhathane ezintathu ze-eccentric zilungele iimeko ezifuna ukutywinwa okuphezulu kunye nokuchasana noxinzelelo oluphezulu kunye namaqondo obushushu, ngelixa iivalvu eziphindwe kabini zibonelela ngesisombululo esinexabiso eliphantsi kwizicelo ezingabizi kakhulu.
