The compression type air bag sealing double-layer ash discharging valve comprises an upper valve body and a lower valve body, wherein the upper valve body and the lower valve body are in flange connection with each other. The compression type air bag sealing double-layer ash discharging valve is characterized in that the upper valve body is a rotary horizontal movement valve; the lower valve body is an air bag sealing valve; a middle stock bin is arranged between the two valve bodies. The compression type air bag sealing double-layer ash discharging valve has the beneficial effects that the lower valve body of the double-layer ash discharging valve is a swing type flat valve; valve plates are of a double-layer structure; a compressible rubber air bag is arranged between the upper valve plate and the lower valve plate; when the lower valve body is closed, the upper valve plate is in contact with the valve bodies, the effects of stopping and blocking materials are achieved, the lower valve body continues to be closed, and therefore the lower valve plate compresses the middle rubber air bag; the air bag is deformed to be in tight contact with the valve bodies, and forced sealing is formed between the upper and lower valve plates and the valve bodies; due to the sealing mode, the non-sealed combined face caused by machining errors and initial abrasion can be compensated, and the valve has the advantages of good sealing performance and small mechanical abrasion.
Description
Technical field
The utility model belongs to valve, particularly has the Double-deck cinder discharge valve of upper and lower two sleeving valves.
Background technique
At present, sintering machine large flue dust removing system, most cone type Double-deck cinder discharge valve or spile type Double-deck cinder discharge valves of adopting.The common shortcoming of unloading valve of these two kinds of forms is, mushroom head or plate (Stamping Steel Ribbon) under the souring of sintered particles, very easily wearing and tearing, causing leaks out has a strong impact on the output of sintering machine, has greatly shortened the working life of equipment.By the observation to Double-deck cinder discharge valve service condition, think, cause the leak out main cause of the serious lost of life of Double-deck cinder discharge valve to be: one, sintered particles, to the washing away of valve plate (mushroom head) in dropping process, forms groove, and then having destroyed the sealing of valve plate, formation is leaked out.Once two formation of leaking out, under the effect of the huge negative pressure of large flue, the material in valve body is taken up by air-flow, and valve inner is formed to huge souring, and the parts such as valve plate valve body are are sharply worn and torn, thus aggravation leak out, even make equipment scrapping.
Model utility content
In order to overcome the deficiency that existing Double-deck cinder discharge valve is easy to wear, working life is short, the purpose of this utility model is to provide a kind of compression type air sac sealing Double-deck cinder discharge valve.
The utility model solves the technological scheme that its technical problem adopts: a kind of compression type air sac sealing Double-deck cinder discharge valve, comprise the upper valve body, the lower valve body that use flange to connect, it is characterized in that: described upper valve body is rotation shiftable valve, described lower valve body is air sac sealing valve, is intermediate bunker between two valve bodies.
Described air sac sealing valve is swing type flat valve, valve seat forms by being fixed on the shelves ring of upper connecting cylinder lower end and being looped around a grade lower connecting cylinder for ring periphery, valve plate is arranged on shelves ring below, by bottom surface, with the upper valve plate of circular orientation projection and end face, the lower valve plate with annular positioning groove forms described valve plate, circular orientation projection is equipped with annular hollow balloon outward, be fixed on the bearing pin of valve plate bottom center through the sleeve of lower valve plate bottom surface, end part of pin shaft is provided with bolt, on sleeve, connecting and controlling the compressing lever that valve plate swings, the compressing lever the other end is arranged on pitman arm shaft.
The valve body top cover of described rotation shiftable valve is provided with material feeding mouth translation valve plate and is positioned at material feeding mouth below, shiftable valve cursor is installed on the central shaft of translation valve plate, this cursor the other end is arranged on rotatingshaft on rotatingshaft and is fixed on valve body top cover by bearing, and the rotatingshaft the other end is connecting shiftable valve drive unit.
Described intermediate bunker is connecting storage bin, and storage bin housing is provided with manhole, and intermediate bunker is provided with intermediate bunker manhole.
The translation valve plate surface spraying of described rotation shiftable valve ceramic wearing coat.
In the utility model, upper valve body is rotary shiftable valve, and the seal valve of this kind of form has following features: 1, wear-resisting property is high, valve plate surface spraying ceramic wearing coat.2, valve plate and valve body Metal Contact, have self-grinding.3, valve plate rotating folding, has reduced the jam of material while closing.4, valve plate and valve body laminating degree are adjustable.
Lower valve body is swing type flat valve, valve plate is double layer construction, Compressible rubber pneumatic bag has been installed, when valve cuts out instantly between upper lower valve plate, top valve plate contacts with valve body, play the effect of cut-off and shutoff material, continue to close lower valve, lower valve plate compression intermediate rubber annular hollow balloon, make air bag distortion and valve body close contact, between upper lower valve plate and valve body, form forced sealing, this kind of seal form, can compensate and cause junction plane not tight because of machining error and initial wear.
This equipment can be installed ripe PLC integrated control system, realize the program control of unloading valve, rely on the piston rod to-and-fro motion of Electrohydraulic push rod, drive shiftable valve to close and open, under normal circumstances, upper valve is normally open valve, when in middle warehouse, material reaches some (by the PLC control time).Upper shiftable valve is closed, when upper valve plate closes to after position limit switch action, position limit switch is connected, thereby show that valve closing puts in place, input signal, give lower valve Electrohydraulic push rod again, control system is controlled lower valve unlatching and is unloaded ash, in the time lag of setting at PLC, unload ash and worked, lower valve is closed.After lower valve is closed and is put in place, upper valve opening.Repeat above-mentioned working procedure.If upper valve closing, do not arrive position limit switch spacing, and pressure relay has been worked, valve plate runs into the special circumstances such as jam can not close while putting in place, and Electrohydraulic push rod will be opened rapidly, and then close, until after the spacing action of position limit switch, lower valve is just started working.So cycle alternation, reaches protection Electrohydraulic push rod motor and sealing and unloads grey object.
The beneficial effects of the utility model are that the lower valve body of this Double-deck cinder discharge valve is swing type flat valve, valve plate is double layer construction, Compressible rubber annular hollow balloon has been installed between upper lower valve plate, when valve cuts out instantly, top valve plate contacts with valve body, play the effect of cut-off and shutoff material, continue to close lower valve, lower valve plate compresses intermediate rubber air bag, make air bag distortion and valve body close contact, between upper lower valve plate and valve body, form forced sealing, this kind of seal form, can compensate and cause junction plane not tight because of machining error and initial wear.There is good seal performance, the advantage that mechanical wear is little.
