Abstract
The utility model relates to a double-seal ash discharging valve for a gravity dust separator of a blast furnace. The double-seal ash discharging valve comprises an upper valve cover (1), an upper valve seat (2), a lower valve plate (3), a lower valve seat (4), a crank arm (10), a rotating shaft (11), a universal joint (12), a transitional connecting rod (6), a sealing ring (5) and a valve body (9); the upper valve cover (1) is connected with an oil cylinder (8) respectively through the universal joint (12), the crank arm (10), the rotating shaft (11) and a swing arm (13); the oil cylinder (8) is fixed on the valve body (9) through a bracket; the circumferential edge of the mushroom-shaped upper valve cover (1) is matched with the upper valve seat (2) to form a first seal; the lower valve plate (3) is connected with an oil cylinder (7) through the transitional connecting rod (6); the sealing ring (5) is embedded on the valve body on the lower valve plate (3); the lower valve plate (3) is matched with the lower valve seat (4) to form a second seal; and both the upper valve cover (1) and the lower valve plate (3) are driven and controlled hydraulically, so that the operation is secure and reliable.
Description
Technical field
The utility model relates to iron and steel metallurgical industry gravity blast furnace dust catcher dust stratification and drains used a kind of valve, is a kind of ash-leaking valve of double sealing structure.
Background technique
The blast furnace that iron and steel metallurgical industry is used to smelt iron, can produce the dust about ton iron 20kg in process of production, these dusts are mixed among the blast furnace gas, following coal gas blows out from furnace roof, deposit collection by gravitational precipitator then, when dust deposit in the gravitational precipitator arrives some, need excrete by the ash-leaking valve that is installed in the gravitational precipitator low side.At present the iron and steel metallurgical industry gravity blast furnace dust catcher still generally adopts the ash-leaking valve of single sealing configuration, and this ash-leaking valve exists poorly sealed and problem such as working life is short.Because blast furnace normal productive process coal gas system has pressure, because above-mentioned ash-leaking valve is single sealing configuration and is manual operation control, just cause gas leakage easily in case be not closed completely, the one, the physical and mental health that threatens the workman, the 2nd, because dust content of gas is bigger, the erosive wear ash-leaking valve causes the ash-leaking valve premature damage easily.At the deficiency of prior art, develop a kind of double sealing structure and can be by the ash-leaking valve of hydraulic operation control, be intended to solve problems such as gravity blast furnace dust catcher ash-leaking valve poorly sealed and working life is short.
Summary of the invention
The purpose of this utility model provides a kind of long service life, the gravity blast furnace dust catcher ash-leaking valve of the double sealing structure of good seal performance.
The purpose of this utility model is achieved through the following technical solutions: it has bonnet, upper valve base, lower valve plate, lower valve base, cranks arm, running shaft, universal joint, transition connecting rod, valve body, oil cylinder and seal ring; Wherein bonnet is a mushroom-like, central position below the bonnet is connected with the universal joint bulb, the lower end of universal joint is connected and fixed with cranking arm, and cranks arm and is connected and fixed with running shaft, and an end of running shaft is connected and fixed with an end of swing arm again, the other end of swing arm is connected with oil cylinder, oil cylinder is fixed on the valve body by bearing, and oil cylinder just can promote swing arm like this, and swing arm just can be rotated by the driven rotary axle, promote bonnet by cranking arm with universal joint then and cooperate, realize the sealing of first road with upper valve base; One end and the transition connecting rod of lower valve plate are connected and fixed, and the transition connecting rod is connected with another oil cylinder, and another oil cylinder just can even promote the lower valve plate fore and aft motion by the transition connecting rod like this, when lower valve plate reaches with the lower valve base cooperation position, realize the sealing of second road; For guaranteeing the sealing effect of second road sealing, inlayed seal ring on the valve body on lower valve plate.
The utility model has the advantages that: finish when letting out grey process, first road seals if not very tight, can seal by second road fully, guarantees sealing effect according to this, avoids valve to blow damage, therefore, can effectively increase the service life; Because this ash-leaking valve can be controlled by hydraulic operation, therefore can alleviate labor strength, improve Labor Safety, and can realize the arbitrarily adjustable and control automatically of opening angle.
Description of drawings
Accompanying drawing 1 is this ash-leaking valve plan view; Accompanying drawing 2 is a left view.
Among the figure: 1 for bonnet, 2 for upper valve base, 3 for lower valve plate, 4 for lower valve base, 5 for seal ring, 6 for transition connecting rod, 7 be an oil cylinder, 8 for another oil cylinder, 9 for valve body, 10 for cranking arm, 11 being swing arm for universal joint, 13 for running shaft, 12.
