A sealed air inlet communicated with an inner interlayer cavity and an electromagnetic valve for controlling the sealing air inlet to be opened or closed are arranged on the upper portion of the whole frame. Compared with the prior art, the combination frame type air-tight seal gas baffle valve has the advantages that the whole frame formed by combining the small frames is high in rigidity, the adverse effect of deformation on the gas valve is avoided, and the popularization of the standardized design of the smoke valve is facilitated; the design of the double layers of shutter baffles is adopted, the inner interlayer cavity is filled with compressed air, sealing check rails are arranged inside the small frames, sealing elastic sheets are arranged at the edges of the shutter baffles, and therefore the pressure of sealing air is guaranteed, and gas leakage is completely avoided; the surfaces of the frames and the surfaces of the double layers of shutter baffles are coated with anticorrosion coatings, the valve is effectively prevented from being corroded by acid gas, and the service life is prolonged.
Description
Technical field
The utility model relates to flue gas desulfurization flapper valve technical field, relates in particular to a kind of combined framework type hermetic seal gas baffle valve.
Background technology
Aspect sintering flue gas desulfurization, generally adopt dry method, wet method and semi-dry desulphurization mode both at home and abroad, flapper valve is as controlling flue collector and bypass flue sealing in flue gas desulfur device or opening the special valve of use.Existing flapper valve adopts venetian blind type structure mostly, and the edge of adjacent blades overlaps mutually, and the problem of its existence is that blade is single blade, and during closed condition, adjacent blades lap-joint is hard contact, and existence is not closed completely, and flue gas is scurried into flue and the equipment corrosion problem of causing.In addition, the gas fume valve using at present generally adopts big frame structure, all rotating vanes are in a framework, Diagonal Dimension is often difficult to guarantee, in manufacture, transportation and installation process, very easily produce distortion, because frame structure insufficient strength produces distortion, cause the situation of smoke spillage to happen occasionally, and frame deformation also easily cause sharf to be out of shape and generation jam, directly affects the use of gas baffle valve.
Summary of the invention
The utility model provides a kind of combined framework type gas baffle valve that is combined into general frame by small frame, adopts the double-deck blinds of anti-corrosion type to add the air impervious form of compression, thoroughly prevents smoke spillage, and has good corrosion resistance.
In order to achieve the above object, the utility model is realized by the following technical solutions:
Combined framework type hermetic seal gas baffle valve, comprise general frame that several small frames are welded, be arranged on double-deck blinds baffle plate in small frame, be arranged on toggle and drive unit outside general frame, general frame top arranges being sealed into gas port and controlling the magnetic valve of seal keying of communicating with interlayer inner chamber.
One group of double-deck blinds baffle plate is installed respectively in described small frame, and sealing blend stop is established with blinds baffle plate contact position in top and under(-)chassis inner side.
Described blinds baffle surface and small frame surface be brushing corrosion-inhibiting coating respectively.
Described blinds baffle edge arranges sealing shell fragment, of stainless steel, makes.
Described magnetic valve and drive unit interlock, control external compressed air break-make, realizes air seal.
Compared with prior art, the beneficial effects of the utility model are:
1) adopt the general frame being combined by small frame, guarantee the rigidity of general frame, prevent that distortion from causing adverse effect to the use of gas fume valve, is also conducive to carry out the standardized designs of gas fume valve simultaneously;
2) adopt double-deck blinds baffle design, and pass into compressed air in interlayer inner chamber, and sealing blend stop is established with blinds baffle plate contact position in top and bottom small frame inner side, and blinds baffle edge arranges sealing shell fragment, guarantee the pressure of sealing air, thoroughly prevent smoke spillage;
3) framework and double-deck blinds baffle surface brushing corrosion-inhibiting coating, effectively prevent the corrosion of sour gas to valve, increases the service life.
