Ielectric hard sealing butterfly valveyakhiwe i-actuator kagesi kanye nevalve uvemvane.Kuyisakhiwo esinamaleveli amaningi ensimbi amathathu eccentric hard sealing.Yamukela indandatho yokuvala yensimbi engenasici emise okwe-U.Indandatho yokuvala enwebekayo yokuvala ixhumene nediski ye-eccentric epholishiwe enezinhlangothi ezintathu.Kungashiwo ukuthi ielectric hard seal butterfly valveinezici zokusebenza ezinhle kakhulu, njengesakhiwo esilula, isisindo esincane, ukufakwa kalula, ukugcinwa okulula, ukusebenza kahle kokuvala uphawu nokunye.
Kufakazele ukuthi i-valve butterfly evala uphawu kagesi eqinile ixazulula inkinga yokuthi indawo evalekile ye-valve uvemvane yendabuko iseku-sliding contact friction ngesikhathi i-valve ivuleka futhi ivala ngo-0 ° ~ 10 °, futhi ifinyelela ukuthi ukuvala idiski ubuso buhlukaniswa ngesikhathi sokuvulwa kwe-valve.Umphumela wokuvala uphawu ufinyelelwa ngesikhathi i-valve ivalwe ngokugcwele.Ngoba ielectric hard seal butterfly valveinesici sokuvala kuqina futhi kuqiniswe.Ngakho-ke ingandisa impilo yesevisi futhi ifinyelele ukusebenza okuhle kakhulu kokuvala.
Ngenxa yalokhu, i-isivalo se-butterfly valveene-actuator kagesi isetshenziswa kabanzi kumapayipi anemithombo yensimbi egqwalayo njengensimbi, amandla kagesi, i-petroleum, imboni yamakhemikhali, umoya, igesi, igesi evuthayo, ukuhlinzekwa kwamanzi kanye ne-drainage enezinga lokushisa eliphakathi elingaphansi kuka-550 ° C.Kuyithuluzi elingcono kakhulu lokulawula ukugeleza nokunqamula uketshezi.
Isitoreji, Ukufakwa kanye nokusetshenziswa
1. Zombili iziphetho zevalvu zizovinjwa futhi zigcinwe ekamelweni elomile nelingena umoya.Kufanele ihlolwe njalo ukuze igcinwe isikhathi eside.
I-2.I-valve izohlanzwa ngaphambi kokufakwa ukuze kuqedwe ukukhubazeka okubangelwa ngesikhathi sokuthutha.
3. Ngesikhathi sokufakwa, amamaki kuvalvu kufanele ahlolwe.Futhi ukunakwa okukhethekile kuzokhokhwa ukuthi isiqondiso sokugeleza kwe-medium sihambisana nalokho okuphawulwe ku-valve.
4. Kumavalve ovemvane ane-actuator kagesi, kuzomele kuqashelwe ukuthi amandla kagesi axhunyiwe kufanele ahambisane nalawo akubhukwana ledivayisi kagesi.
