Abstract
The invention relates to an automatic flow regulating valve for a grate cooler. The automatic flow regulating valve is characterized by comprising a valve body, a valve plate, a bottom air plate and a valve plate bob-weight, wherein the valve body and the bottom air plate are connected into a whole through welding; the valve plate and the valve plate bob-weight are connected through welding; a hook rail is arranged in the valve body, the hook rail is used for hanging the valve plate on the valve body; the top of the valve body is provided with a bolt hole; and the valve body and the wallboard of the grate cooler are connected and hung on the valve plate by a bolt. The automatic flow regulating valve provided by the invention has the following advantages: (1) because the bottom air plate is an arc open hole, the problems that the grate cooler material bed waves and an air supply system automatically balances are solved; (2) the bottom air plate and the valve body are connected into a whole so as to simplify the structure; and (3) the valve plate is thin and is only 12mm, the weight is concentrated on a hybridization block, the gross weight is lighter, and the manufacturing cost is reduced.
Description
Technical field
What the present invention 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 prior art 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 present invention 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.
Technical solution of the present invention: 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 are through being welded to connect; A peg is arranged 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.
Advantage of the present invention: 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; Wherein valve body 1 and bottom aerofoil 3 are through being welded and fused; 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.
