Embodiment
Referring to drawings and Examples the utility model is described in detail:
Accompanying drawing 1 as can be known, a kind of boiler dust remover by-pass valve seal arrangement, comprise valve body 1, valve body 1 is interior to be arranged valve plate 2, lower valve plate 3, interior valve port 4, outer valve port 5 and drives upper valve plate 2 and pneumatic actuating device 6 that lower valve plate 3 moves up and down, and inside and outside circle side face and the end face of described interior valve port 4 and outer valve port 5 ends are coated with sealing valve port bar 7; Circumferential edges and the circumferential surface of upper valve plate 2 upper surfaces and lower surface are coated with valve plate Stamping Steel Ribbon 8; Circumferential edges and the circumferential surface of lower valve plate 3 upper surfaces and lower surface are coated with lower valve plate Stamping Steel Ribbon 9; The sealing valve port bar 7 of the described inside and outside circle side face that is coated on interior valve port 4 and outer valve port 5 ends and end face is fixing by bolt 10; Described bolt 10 is 100mm along circumferential spacing; The upper valve plate Stamping Steel Ribbon of the described circumferential edges that is coated on valve plate 2 upper surfaces and lower surface and circumferential surface is fixing by bolt 10; Being coated on the circumferential edges of lower valve plate 3 upper surfaces and lower surface and the lower valve plate Stamping Steel Ribbon of circumferential surface fixes by bolt 10; Described bolt 10 spacings are 100mm; The cloth bag that described sealing valve port bar 7, upper valve plate Stamping Steel Ribbon 8 and lower valve plate Stamping Steel Ribbon 9 are made by double-deck polyphenylene sulfide fibre consists of; The bolt 10 of described fixedly valve port Stamping Steel Ribbon 7 is arranged at the downward 100mm of valve port; The bolt 10 of described fixing upper valve plate Stamping Steel Ribbon 8 is arranged on the upper valve plate 2 along diameter of phi 1100mm; The bolt of described fixedly lower valve plate Stamping Steel Ribbon 9 is arranged on the lower valve plate 3 along diameter of phi 900mm.
The flue-gas temperature of boiler sack cleaner import is generally between 140 ℃-150 ℃, contain CO, CO2, SO2, SO3 and a large amount of flue dust in the flue gas, the sealing material that the by-pass valve valve port uses is silica gel strip, silica gel strip is crisp rigid the wearing out of operation appearance under this environment for a long time, and abrasion condition is also more serious.Judge that by analysis the sealing material of by-pass valve employing is unsuitable for the working environment at this place, find that simultaneously the by-pass valve opening processing process is coarse, two kinds of factors cause the sack cleaner by-pass valve often to occur leaking.
Use the felt bar to replace silica gel strip to test as sealing material, move after three months, the felt bar also occurs crisp rigid aging, and by-pass valve leaks again, causes smoke content to exceed standard.
Made by polyphenylene sulfide fibre through research boiler sack cleaner cloth bag, its characteristics are: inorganic acid resistance, Organic Acid and Base, organic solvent; Very strong stability to hydrolysis resistance and flame retarding are arranged; Tension, ability wear-resistant, anti-folding are good, and operating temperature is generally 160 ℃, moment operating temperature＜190 ℃, 285 ℃ of fusing points; Oxygen content 10% or following occasion all applicable, find that its various performances all can adapt to the residing working environment of by-pass valve.
The utility model boiler dust remover by-pass valve seal arrangement thoroughly solves the production difficult problem that sack cleaner by-pass valve valve port is sewed, and realizes the boiler smoke qualified discharge, reduces the shutdown maintenance number of times.
