Description
Technical field
the utility model relates to the pneumatic door device of a kind of sealing, is particularly applicable to need in the six road parts of thermal power plant the composite seal pneumatic door of the isolated occasion of shutoff fast.
Background technique
pneumatic gate valve is the flow of a kind of powder, crystal grain material, granule and piece material or the major control equipment of quantity delivered, is widely used in the industry control changes in flow rate such as metallurgy, mine, building materials, grain, chemical industry or cuts off rapidly flow.
the leakproofness of spile type isolating door is better than baffle-type air door, is usually used in such as coal pulverizer inlet hot-flow flue, and many engineerings are due to this Men Buyan, and while stopping grinding, hot blast flows into and burns out belt coal-feeding machine; Combustor inlet isolating door, because coal powder density is high and stop grinding maintenance safety requirement, has spile type isolating door only and just can meet the isolated requirement of abrasionproof; Flue gas air door before deduster, as considered, deduster maintenance must adopt spile type isolating door.
the conventional spile type isolating door that present most occasion is used all adopts door-plate bottom to be furnished with guide wheel and road wheel is realized mobile, door-plate propulsion cylinder not only will overcome the friction between road wheel and guide rail, friction between guide wheel and guide rail also will overcome the resistance that dust stratification brings simultaneously.Once dust stratification is serious, make total frictional force become geometrical progression to rise, cause door-plate to move and be obstructed, cause air door seal failure.All there is the defect fitting badly in all power plant, for example, when coal pulverizer inspection, maintenance, hot blast cannot completely cut off, and can only take that coal pulverizer is exported to fast valve and open always, is communicated with burner hearth, once combustion chamber draft fluctuation becomes malleation, has great human injury hidden danger.These defects have greatly affected the overall operation of equipment, even may cause the major accidents such as blowing out.
Model utility content
the open a kind of two baffle plate hermetic seal pneumatic door devices of the utility model, its objective is provide a kind of rational in infrastructure, operate easy and convenient, quality of processing is high, good work environment, strong, the safe and reliable two baffle plate hermetic seal pneumatic door devices of seal.
for achieving the above object, the utility model is achieved through the following technical solutions.A kind of composite seal pneumatic door, comprise the structures such as guiding road wheel, guide rail, keying cylinder, sealing and pumping device, packing, seal frame, case frame, wear-resistant baffle plate, independent two-orbit baffle plate, it is characterized in that: guiding road wheel is fixed on guide rail, sealing and pumping device is positioned at seal frame upside, packing is positioned at seal frame edge, seal frame is placed in case frame surrounding, and wear-resistant baffle plate and independent two-orbit baffle plate are placed along respective track.
described wear-resistant baffle plate has two-layer, respectively in independent two-orbit baffle plate both sides.
described independent two-orbit baffle plate is positioned in the middle of case frame.
in described independent two-orbit baffle plate, two-layer baffle plate is take spacing as 100mm parallel motion.
between described independent two-orbit baffle plate and the wear-resistant baffle plate of both sides, spacing is 300mm.
