Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an electric flow regulating valve. Background Art

[0002] Valves are devices that control the flow of fluids (liquids, gases, steam, etc.) and are commonly found in piping systems. They can be used to adjust flow, stop fluid flow, adjust pressure, etc. There are many types of valves, including gate valves, ball valves, butterfly valves, stop valves, etc. Electric flow control valves are valves controlled by electric actuators and are generally used in inclined conveying devices such as chutes. As a powder material flow control valve, the cross-sectional area of ​​the cylinder inside the valve is adjusted through an electric actuator or a pneumatic controller to change the amount of material passing through the chute.

[0003] Existing electric flow control valves generally do not have anti-clogging mechanisms. When transmitting powdered materials, the powdered materials are prone to accumulate and agglomerate during the flow process, which may cause valve blockage, affect flow regulation and normal system operation, and reduce the service life of the electric flow control valve. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing electric flow regulating valve generally has no anti-blocking mechanism, which may cause valve blockage when transmitting powdery materials, thereby reducing the service life of the electric flow regulating valve.

[0006] Through the above technical solution, the dredging shaft moves to dredge the discharge pipe, thereby preventing the powdered material from piling up and agglomerating during the flow process, thereby ensuring the normal operation of the electric flow control valve.

[0007] The utility model is further configured that two fixed shafts are fixedly connected in the regulating valve body, the two fixed shafts are slidably connected to the two connecting ears respectively, a discharge pipe is fixedly connected to one side of the regulating valve body, and the dredging shaft is opposite to the discharge pipe.

[0008] Through the above technical solution, the cylinder drives the sliding plate to slide along the track of the fixed axis, so that it moves on a specific path, achieving precise positioning and control, and improving the work efficiency of clearing the discharge pipe.

[0009] The utility model is further configured such that a support base is fixedly connected to the bottom of the regulating valve body, an electric actuator is fixedly connected to the side of the support base away from the regulating valve body, an output end of the electric actuator is fixedly connected to a first rotating rod, and the other end of the first rotating rod is fixedly connected to a first connecting shaft.

[0010] The utility model is further configured such that a connecting rod is rotatably connected to one side of the electric actuator, a first margin hole and a second margin hole are respectively provided at both ends of the connecting rod, the first margin hole is slidably connected to the first connecting shaft, a second connecting shaft is slidably connected in the second margin hole, and one end of the second connecting shaft is fixedly connected to a second rotating rod.

[0012] Through the above technical solution, the electric actuator works and cooperates with the connecting rod mechanism to make the flow plate rotate. The rotation angle of the flow rotating plate can accurately control the flow of powdered materials, which can meet different process requirements, minimize the pressure loss during the transmission of powdered materials, improve the stability and reliability of the valve, improve the efficiency of the system, and adjust the flow of materials as needed, reduce the frequent opening and closing of the valve, and extend the service life of the valve.

[0014] With the above technical solution, the operator turns the gate and inflates the sealing ring to expand it and fill the feed pipe, forming a good seal, thereby preventing the powdered material from passing through. When the material needs to be transported further, the sealing ring gas is released to restore its original shape, and the gate is turned in the opposite direction, so that the sealing ring is away from the feed pipe and the material is allowed to pass through.
