Namuhla, iama-eccentric butterfly valvesyefekthri yethu i-DN1000 ne-DN1200 ipakishiwe futhi isilungele ukulethwa. Leli qoqo lama-valve uvemvane lizothunyelwa eRussia.

Amavalvu ovemvane ane-eccentric kabili kanye namavalvu ovemvane ajwayelekile ayizinhlobo zamavalvu ezivamile, futhi ayahluka ngokwakheka nokusebenza. I-valve butterfly eccentric kabili iwuhlobo lokusebenza okuphezului-valve ye-butterfly ene-flanged, ithuthukiswa ngesisekelo se-valve uvemvane olulodwa oluyi-eccentric, futhi i-valve uvemvane evamile ngokuvamile ibhekisela emgqeni ophakathi valve uvemvane uphawu.

Isakhiwo se-double eccentricintengo uvemvane valveibonakala nge-axis ye-stem yayo ichezuka phakathi nendawo ye-butterfly plate futhi isuka maphakathi nomzimba. Lo mklamo wenza i-valve ngemva kokuvulwa, i-disc ingasuswa ngokushesha esihlalweni, isuse kakhulu ukukhishwa okungadingekile ngokweqile nokunwaya okwenzeka phakathi kwe-disc nesihlalo, ngaleyo ndlela kunciphise ukungqubuzana nokugqoka, futhi kuthuthukise ukusebenza kokuvala kanye nempilo yesevisi ye i-valve.

Isakhiwo se-valve ye-butterfly evamile silula, i-axis ye-stem, ipuleti levemvane kanye nomzimba kusesimweni esifanayo, futhi izimpawu ezithambile zivame ukusetshenziswa, njengerabha noma i-polytetrafluoroethylene nezinye izinto, ezifanele ukusetshenziswa izinga lokushisa elivamile kanye nemvelo yengcindezi ephansi futhi ibe nokusebenza okuhle kokuvala uphawu.

I-valve uvemvane oyi-eccentric ephindwe kabili isebenza ngokufana ne-valve uvemvane oluyi-eccentric eyodwa, kodwa ngenxa yedizayini ye-eccentric ephindwe kabili, inokusebenza okungcono kokuvala kanye nokungqubuzana nokuguga okuphansi. Umgomo wokusebenza we-valve uvemvane ovamile ukulawula ukugeleza koketshezi ngokuzungezisa ipuleti le-valve, futhi indlela yokuzungezisa yepuleti ye-valve inquma ukugeleza koketshezi. Ngenxa yesakhiwo sayo esilula, phakathi nenqubo yokuvula nokuvala i-valve ye-butterfly evamile engu-6 intshi, ipuleti levemvane nesihlalo kuhlale kusesimweni sokucindezela nokukhuhla, okungase kubangele ukungqubuzana okukhulu nokugqoka.

I-valve yevemvane eyi-eccentric ephindwe kabili ifanele izitshalo zamanzi, izimboni zamandla, ukuncibilika kwensimbi, imboni yamakhemikhali, ubunjiniyela bemithombo yamanzi, ukwakhiwa kwezindawo zemvelo nokunye ukugeleza kwesistimu, okufanelekile ikakhulukazi ukusetshenziswa kwamapayipi amanzi njengokulawula nokuvala okokusebenza.
