Ivalvu yeButterfly ephindwe kabini vs iValve yeButterfly ephindwe kathathu？

Yintoni umahluko phakathi kwevalvu yebhabhathane ephindwe kabini ne-eccentric kathathu?

Kwiivalvu zemizi-mveliso, zombini iivalvu zebhabhathane ezingaqhelekanga ezimbini kunye neevalvu zebhabhathane ezingaqhelekanga ezintathu zingasetyenziswa kwioyile negesi, kwiikhemikhali namanzi, kodwa kunokubakho umahluko omkhulu phakathi kwezi ntlobo zimbini zeevalvu zebhabhathane, ngoko ke kubalulekile ukwazi umahluko phakathi kwezi ntlobo zimbini zeevalvu ukuze wenze ukhetho olufanelekileyo.

Kweli nqaku, siza kujonga umahluko ophambili phakathiiivalvu zebhabhathane eziphindwe kabinikwayeiivalvu zebhabhathane eziphindwe kathathukunye neenzuzo kunye nezicelo zazo.

Okokuqala, uyilo kunye nolwakhiwo lwahlukile.

Idiski yeivalvu yebhabhathane engaqhelekanga kabiniisuswe kumgca ophakathi womzimba wevalvu kunye neshaft. Olu yilo lwe-offset lunceda ukungqubana kunye nokuguga kwesihlalo sevalvu ethambileyo ngexesha lokuvulwa nokuvalwa, ngaloo ndlela kwandisa ubomi benkonzo kunye nokuphucula ukutywinwa. Ngelixa ivalvu yebhabhathane ebizwa ngokuba yi-triple eccentric ene-eccentric yesithathu ine-eccentric yesithathu phezu kwe-eccentric ephindwe kabini, oko kukuthi, yenza imilo ekhonkrithi kumphezulu wokutywinwa, kwaye izinto zomphezulu wokutywinwa zihlala zitywinwa ngesinyithi, nto leyo ebangela ukutywinwa okuqinileyo kunye nokungqubana okuncinci, okwenza ukuba ilungele ukusetyenziswa koxinzelelo oluphezulu kunye nobushushu obuphezulu.

Okwesibini, ukusebenza kwahlukile.

Iivalvu zebhabhathane ezingaqhelekanga ezintathuInika iingenelo ezininzi ngaphezu koyilo oluphindwe kabini oluyi-eccentric. Uyilo oluyi-eccentric oluyi-triple lunika isivalo esingangeni moya, nto leyo ethetha ukuba ukuvuza kunokuthintelwa ngempumelelo naphantsi koxinzelelo oluphezulu kunye neemeko zobushushu obuphezulu. Ngoko ke lufanelekile ngakumbi kwizicelo ezibalulekileyo ezifuna ukuvalwa okuqinileyo. Ukongeza, uyilo lwekhoni yesigqubuthelo se-triple eccentric butterfly valve luphucula ukumelana nokuguguleka ukuze amaxesha okugcina ande kwaye iindleko zokulungisa zincitshiswe. Ezi zibonelelo zokusebenza zenza i-triple eccentric butterfly valve ibe lukhetho lokuqala kwizicelo ezifuna uncedo kwi-oyile negesi, i-petrochemical kunye nemizi-mveliso yombane.

Ekugqibeleni,Azisetyenziswanga iindleko zokwakha.

Eyona nzuzo inkulu yeivalvu yebhabhathane engaqhelekanga kabiniXa kuthelekiswa nevalvu yebhabhathane engaqhelekanga kathathu, ixabiso lokwakha liphantsi kancinci. Ukuba iimeko zokusebenza azifuni ubushushu obuphezulu kunye nevalvu yebhabhathane engaqhelekanga kathathu engaqhelekanga, ivalvu yebhabhathane engaqhelekanga kabini lukhetho olungabizi kakhulu. Oku kungenxa yokuba iivalvu zebhabhathane ezingaqhelekanga ezimbini zifanelekile kwizicelo ezibandakanya uxinzelelo oluphantsi ukuya koluphakathi kunye namaqondo obushushu. Ukusebenza kwazo okuthembekileyo kunye nokusebenza kakuhle kweendleko kuzenza zibe lukhetho oludumileyo kwiintlobo ngeentlobo zezicelo zoshishino.

Ukuqukumbela, ukhetho phakathi kwe-double kunye ne-iivalvu zebhabhathane ezingaqhelekanga ezintathukuxhomekeke kwiimfuno ezithile zesixhobo kunye nendawo esingqongileyo. Iivalvu zebhabhathane ezi-eccentric ezintathu zifanelekile kwiimeko ezifuna ukutywinwa okuphezulu kunye nokuxhathisa uxinzelelo oluphezulu kunye namaqondo obushushu, ngelixa iivalvu ezi-eccentric ezimbini zibonelela ngesisombululo esingabizi kakhulu kwizicelo ezingabizi kakhulu.
