Description

Technical Field

[0001] The utility model belongs to the technical field of valve control, and in particular relates to an automatic control driving device for industrial pipeline valves. Background Art

[0002] Pipeline refers to the pipes connecting pumps, valves or control systems, etc., used to transport liquids, gases or powdered solids. Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the transported medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.

[0003] However, the existing pneumatic devices for industrial pipeline valves are large in size, heavy in weight, and have a slow opening speed, which affects the overall control efficiency. Utility Model Content

[0004] The utility model aims to provide an automatic control drive device for industrial pipeline valves, so as to solve the above problems existing in the prior art, save materials and energy, reduce the weight of workpieces, reduce the volume, and improve production efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for automatic control and driving of industrial pipeline valves, comprising a box body and cylinder barrels respectively arranged at both ends of the box body, wherein both ends of the box body are open and connected, and the two ends of the box body are respectively connected with the two cylinder barrels, a piston is slidably arranged in each of the cylinder barrels, and the pistons of the two cylinder barrels are located on the same axis, a main shaft is horizontally rotated in the box body, a driving arm is arranged on the main shaft and the main shaft is connected to the middle part of the driving arm to drive the rotation, a connecting rod is respectively hinged at both ends of the driving arm, and the other end of each connecting rod is hinged to the piston in the corresponding direction, a first air inlet is opened on the side of each of the cylinder barrels, and a second air inlet is respectively arranged at both ends of the side of the box body, the moving range of the piston is between the first air inlet and the second air inlet, and the main shaft is coaxially connected to the valve outward to drive the valve to open and close.

[0007] The working process and principle of the above structure are as follows:

[0008] During operation, when 0.4Mpa-0.7Mpa compressed air is injected into the two first air inlets at the same time, the two pistons move relative to each other along the cylinder at the same time, and the two connecting rods drive the driving arms to rotate, and then the driving arms drive the main shaft to rotate, driving the valve to open; on the contrary, when 0.4Mpa-0.7Mpa compressed air is injected into the two second air inlets at the same time, the two pistons move towards each other under the action of gas pressure, and the driving arms are driven to rotate in the opposite direction by the two connecting rods, and then the main shaft drives the valve to close. The piston pulls the connecting rod and the driving arm as a whole to drive the main shaft to rotate 90° forward and reverse, thereby driving the valve to open and close. The overall structure is simpler, the weight of the workpiece is reduced, the volume of the driving mechanism is reduced, and the two-way drive improves the efficiency of valve opening and closing, thereby improving the overall production efficiency.

[0009] Furthermore, the vertical cross-section in the middle of the box body is circular and the circular cross-section is coaxially arranged with the main axis.

[0010] Such an arrangement ensures that the rotation of the driving arm is not hindered, making it easier for the piston to drive the driving arm to rotate.

[0011] Furthermore, a section of round tube is formed at both ends of the box body, and the diameter of the round tube is the same as the inner and outer diameters of the cylinder.

[0012] The setting of the round tube is mainly to facilitate the coordination with the cylinders at both ends to ensure its connectivity and sealing and prevent leakage due to mismatch.

[0013] Furthermore, the cylinder barrel and the housing are sealed and connected via a flange and fastened via bolts.

[0014] The cylinder barrel and the box body are connected by flanges to ensure their sealing and connection firmness.

[0015] Furthermore, the second air inlet is arranged at a position close to the connection between the box body and the cylinder barrel.

[0016] The limitation of the position of the second air inlet ensures the determination of the moving range of the piston and, at the same time, enables the driving arm to rotate up to 90° to ensure that the valve is fully opened or fully closed.

[0017] Furthermore, the driving arm has a diamond-shaped structure.

[0018] The diamond-shaped driving arm ensures the stability of its operation.

[0019] Furthermore, a hinged seat is provided on the side of the piston close to the box body.

[0020] The setting of the hinge seat facilitates the hinge connection between the piston and the connecting rod.

[0021] Beneficial effect: When the utility model is working, when 0.4Mpa-0.7Mpa compressed air is injected into the two first air inlets at the same time, the two pistons move relative to each other along the cylinder at the same time, and the two connecting rods drive the driving arms to rotate, and then the driving arms drive the main shaft to rotate, driving the valve to open; on the contrary, when 0.4Mpa-0.7Mpa compressed air is injected into the two second air inlets at the same time, the two pistons move towards each other under the action of gas pressure, and the two connecting rods drive the driving arms to rotate in the opposite direction, and then the main shaft drives the valve to close, and the piston pulls the connecting rod and the driving arm as a whole to drive the main shaft to rotate 90° forward and reverse, thereby driving the valve to open and close. The overall structure is simpler, the weight of the workpiece is reduced, the size of the driving mechanism is reduced, and the two-way drive improves the efficiency of valve opening and closing, thereby improving the overall production efficiency.

[0027] like Figure 1 and Figure 2As shown, this embodiment provides an automatic control drive device for industrial pipeline valves, including a box body 1 and cylinder barrels 2 respectively arranged at both ends of the box body 1, the two ends of the box body 1 are open and through, the two ends of the box body 1 are respectively connected with the two cylinder barrels 2, a piston 3 is slidably arranged in each cylinder barrel 2, the pistons 3 of the two cylinder barrels 2 are located on the same axis, a main shaft 4 is horizontally rotated in the box body 1, a driving arm 5 is arranged on the main shaft 4, and the main shaft 4 is connected to the middle part of the driving arm 5 to drive it to rotate, a connecting rod 6 is respectively hinged at both ends of the driving arm 5, and the other end of each connecting rod 6 is hinged to the piston 3 in the corresponding direction, a first air inlet 7 is opened on the side of each cylinder barrel 2, and a second air inlet 8 is respectively arranged at both ends of the side of the box body 1, the moving range of the piston 3 is located between the first air inlet 7 and the second air inlet 8, and the main shaft 4 is coaxially connected to the valve outward to drive the valve to open and close.

[0028] The working process and principle of the above structure are as follows:

[0029] During operation, by injecting 0.4Mpa-0.7Mpa compressed air into the two first air inlets 7 at the same time, the two pistons 3 move relative to each other along the cylinder 2 at the same time, and the two connecting rods 6 drive the driving arms 5 to rotate, and then the driving arms 5 drive the main shaft 4 to rotate, driving the valve to open; on the contrary, when 0.4Mpa-0.7Mpa compressed air is injected into the two second air inlets 8 at the same time, the two pistons 3 move towards each other under the action of gas pressure, and the driving arms 5 are driven to rotate in the opposite direction by the two connecting rods 6, and then the main shaft 4 drives the valve to close. The piston 3 pulls the connecting rod 6 and the driving arm 5 to drive the main shaft 490° forward and reverse rotation, driving the valve to open and close. The overall structure is simpler, the weight of the workpiece is reduced, the volume of the driving mechanism is reduced, and the two-way drive improves the efficiency of valve opening and closing, thereby improving the overall production efficiency.

[0030] In another embodiment of the present invention, Figure 1 and Figure 2 As shown, the vertical cross-section of the middle of the box body 1 is circular and the circular cross-section is coaxially arranged with the main shaft 4.

[0032] In another embodiment of the present invention, Figure 1 and Figure 2 As shown, a section of round tube is formed at both ends of the box body 1, and the diameter of the round tube is the same as the inner and outer diameters of the cylinder 2.
