Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of good airproof performance and the effective Pneumatic slag discharging valve of deslagging.
For achieving the above object, the utility model provides following technological scheme: a kind of Pneumatic slag discharging valve, comprise cylinder, support, valve body and be located at the flashboard in valve body, described valve body comprises liquid entering hole and liquid outlet, described cylinder and flashboard are connected, the bottom of described valve body and flashboard connecting part are provided with dump tank, the corresponding dump tank of described liquid outlet place side convexes with limit flange, relative limit flange one side of described flashboard is provided with the first sphenoid surface, described limit flange is provided with the second sphenoid surface for being close to the first sphenoid surface, one side of the relative dump tank of described limit flange is provided with the first arc shaped surface, a described limit flange dorsad side of flashboard is provided with the second arc shaped surface.
By adopting technique scheme, under the driving of flashboard at cylinder, decline, fit tightly to the first sphenoid surface and the second sphenoid surface, limit flange provides a holding power in liquid outlet one side for flashboard, do not make flashboard yielding and produce leakage point, and due to the mutual extruding between two sphenoid surface, one side and the valve body of the relative liquid entering hole of flashboard are fitted tightly, good airproof performance, and the first arc shaped surface coordinates the round and smooth space of formation with dump tank, be easy to deslagging, the second arc shaped surface that is arranged at liquid outlet one side forms heavy caliber liquid outlet, when realizing smooth deslagging, level and smooth cambered surface is difficult for accumulated slag, deslagging is effective.
The utility model is further set to: described liquid entering hole and flashboard contacting part are provided with seal ring.
By adopting technique scheme, due to the mutual extruding between flashboard and liquid entering hole, make to form elastic packing between flashboard and liquid entering hole, reduce leakage point, improve sealing.
The utility model is further set to: described seal ring is provided with some juts, between described neighboring projection portion, forms depressed part, and described jut and flashboard butt arrange.
By adopting technique scheme, the seal ring so arranging is equivalent to a plurality of concentric seal rings one-body molded, plays multi-sealed effect, good airproof performance.
The utility model is further set to: described valve body is provided with filler chamber, and described filler chamber bottom is provided with scraping blade, and described scraping blade and flashboard butt arrange.
By adopting technique scheme; in the process in flashboard rise and fall; medium residue residual on flashboard is easily pulled the filler in filler chamber; form the external leakage of valve; after filler chamber bottom arranges scraping blade; medium residue on flashboard is scraped by scraping blade, protection filler, good airproof performance.
