Abstract
The utility model discloses an automatic flow control valve of a grate cooler, which is characterized in that the automatic flow control valve comprises a valve body, a valve plate, a bottom air foil and a valve plate counter weight, wherein the valve body and the bottom air foil are connected into a whole body by welding; the valve plate is connected with the valve plate counter weight through welding; a hook rail which hooks the valve plate on the valve body is arranged in the valve body; bolt holes are arranged on the top of the valve body; and the valve body is connected with a wall panel of the grate cooler through bolts and the valve plate is hooked. The automatic flow control valve has the advantages that: 1) the bottom air foil is provided with an arced opening, which well solves the problem of automatic balance between the fluctuation of a material layer and an air supply system of the grate cooler; 2) the bottom air foil and the valve body are connected into a whole, which simplifies the structure; 3) the valve plate is only 12mm thick and the weight can be centralized on the counter weight, which lightens the total weight and reduces the manufacturing cost.
Description
Technical field
What the utility model proposed is a kind of automatic flow modulating valve of cooling machine cooling air supply; It is the air quantity flow control valve of a kind of unpowered driving, gravity adjusting, compensation automatically, automatic adaptive system balance, can satisfy the process engineering progress requirement of cooling machine air feed system.
Background technique
The modulating valve of existing technology such as F.L.Smidth; Its structure is to be made up of aperture one by one at the aerofoil of its bottom; The bottom aerofoil is to be connected on the valve plate; Valve plate is very thick, because the aerofoil of bottom is made up of aperture one by one, it just can not fine solution cooling machine bed of material fluctuation and air feed system autobalance problem.The bottom aerofoil is connected on the valve plate, and very thick valve plate makes very heavy that its structure seems complicated, valve is done, waste material.
Summary of the invention
What the utility model proposed is a kind of automatic flow modulating valve of cooling machine cooling air supply, and its purpose is intended to overcome the existing above-mentioned defective of existing skill wood.Have characteristics such as cooling machine bed of material fluctuation and air feed system autobalance, simple in structure, low cost of manufacture.
The technical solution of the utility model: its structure comprises valve body, valve plate, bottom aerofoil, valve plate counterweight; Wherein valve body and bottom aerofoil are through being welded and fused; Valve plate and valve plate counterweight have a peg through being welded to connect in valve body, this peg hangs over valve plate on the valve body; Have bolt hole at the valve body top, valve body and cooling machine wallboard are connected and hang up the effect that valve plate can realize regulating automatically air quantity with bolt.
The advantage of the utility model: 1) because the bottom aerofoil is an arc perforate, can fine solution cooling machine bed of material fluctuation and air feed system autobalance problem.2) the bottom aerofoil is to link to each other with valve body to be integrally formed, and simplifies the structure.3) valve plate is very thin, and only 12mm can focus on weight on the breeding piece, and gross weight is lightened, and reduces manufacture cost.
Description of drawings
Accompanying drawing 1 is the structural representation of the automatic flow modulating valve of cooling machine cooling air supply.
Among the figure 1 is valve body, the 2nd, valve plate, the 3rd, bottom aerofoil, the 4th, valve plate counterweight.
Embodiment
The contrast accompanying drawing; Its structure comprises valve body 1, valve plate 2, bottom aerofoil 3, valve plate counterweight 4, and wherein valve body 1 and bottom aerofoil 3 are through being welded and fused, and valve plate 2 and valve plate counterweight 4 are through being welded to connect; A peg is arranged in valve body; This peg hangs over valve plate 2 on the valve body 1, has bolt hole at valve body 1 top, valve body and cooling machine wallboard are connected and hangs up the effect that valve plate can realize regulating automatically air quantity with bolt.
Valve body 1 effect is to stop unnecessary air quantity to get into valve body, and air can only be through fixedly vent hole and the bottom aerofoil air intake on the valve body, and valve plate 2 can be with who knows that variation in pressure changes the position, and cooperates the effect of realization adjusting flow with the bottom aerofoil.On the aerofoil 3 of bottom an arc perforate is arranged, fine solution cooling machine bed of material fluctuation of ability and air feed system autobalance problem have been optimized the structure of bottom aerofoil simultaneously again, can cooperate valve plate to make the air quantity adjusting be more suitable for the 4th generation cooling machine.The moving range of valve plate on the aerofoil of bottom is 0 ° to 42 °, when valve plate nature suspended state, is 0 °, and be maximum through the air quantity of modulating valve, when valve plate swings upwards into 35-42 °, minimum through the air quantity of modulating valve.The air quantity of each air compartment of cooling machine, blast are all different, and valve plate counterweight 4 can change valve plate, only adjusts counterweight and just can be implemented in the application in each air compartment of cooling machine.
During work, when material bed pressure increases, will be to valve plate 2 one down pressures, valve plate 2 moves down, and it is big that bottom aerofoil aperture becomes, and air inflow increases, and when material bed pressure reduced, valve plate 2 upwards slided, and air inflow is corresponding to be reduced.The effect that the valve plate material feeding is pressed swings up and down, and when upwards swinging, bottom aerofoil vent hole diminishes, and when lower swing, it is big that bottom vents becomes.Make the aperture size along with the variation automatic reverse of material bed pressure is regulated, with the control air inflow.Valve plate is in free state of suspension all the time under the effect of gravity and pressure in normal operation, and compensation automatically.
The cooling machine of different size, choose air quantity, blast parameter according to factors such as different altitude above sea level after, design the flow control valve of this condition of adaptation, be installed in the bed of combing and go up and get final product.
