Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an automatic valve safety loop operation control device. Background Art

[0002] A valve is a mechanical device that controls the flow rate, direction, pressure, temperature, etc. of a flowing fluid medium. An automated valve control device is a device used in conjunction with a valve to control the opening and closing of an electric valve to ensure the safety of the valve circuit operation.

[0003] The existing technical authorization announcement number CN219954391U patent document provides a safety valve controller. When the controller body is damaged, the utility model only needs to pull the operating block through the operating handle to drive the sliding card rod to move and make the sliding card rod disengage from the slot, and then the controller body can be conveniently disassembled, thereby facilitating maintenance or replacement of the controller body. After the maintenance is completed, it is only necessary to insert the bottom of the controller body into the valve body, and then, under the elastic force of the sleeve spring, drive the sliding card rod to be stuck in the corresponding slot, thereby achieving convenient fixation of the controller body, and by providing a sealing gasket and a sealing ring, the sealing of the connection between the controller body and the valve body is increased, thereby ensuring the stability of the operation of the controller body.

[0004] However, the existing automated valve safety circuit operation control device is not convenient for ensuring the stability of the connection between the controller and the valve when in use. The existing technology uses the elastic potential energy of the spring to fix the connection between the controller and the valve. During the long-term use of the device, the spring is repeatedly compressed under force, which will cause its elastic potential energy to fail, and the controller is prone to loosening and falling off, affecting the safety and stability of the controller's control over the valve circuit operation.

The plug-in positioning rod 404 is moved to the right side, so that the plug-in positioning groove 405 is connected to the fixed through hole 606, thereby ensuring the stability of the connection between the valve controller 2 and the valve body 1. When the valve controller 2 needs to be repaired, the staff operates the drive motor 401 to drive the two sets of internal thread moving blocks 403 to move outward on the bidirectional screw rod 402, so that the plug-in positioning rod 404 extends from the plug-in positioning groove 405 and the fixed through hole 606.

The outer wall of the internal thread moving block 403 is fully fitted with the inner wall of the rectangular groove 601. One side of the internal thread moving block 403 is fixedly connected to the linkage plate 602, and the side of the linkage plate 602 away from the internal thread moving block 403 is fixedly connected to the connecting plate 603. The inner side of the connecting plate 603 is fixedly connected to the connecting column 604, and the end of the connecting column 604 away from the connecting plate 603 is fixedly connected to the sealing gasket 605.

The docking block 503 on the built-in frame 502 and the docking groove 504 on the inner side of the mounting seat 3 are on the same plane. The staff will connect the valve controller 2 to the mounting seat 3. The built-in frame 502 is inserted into the mounting seat 3, and the docking block 503 is connected to the docking groove 504. After they are fully connected, the fixed through hole 606 on the connecting seat 501 corresponds to the plug-in positioning groove 405 on the mounting seat 3, and the internal thread moving block 403 drives the linkage plate 602 to move, and the linkage plate 602 drives the connecting plate 603 to move toward the middle, and the connecting plate 603 drives the connecting column 604 to move, so that the plug-in positioning rod 404 is connected to the plug-in positioning groove 405 through the fixed through hole 606, thereby ensuring the stability of the connection between the valve controller 2 and the valve body 1.

[0028] Working principle: When using the device to perform automated control operations on the operation of the valve safety circuit, the staff places the valve controller 2 on the top of the mounting seat 3, and makes the built-in frame 502 fully correspond to the inner cavity of the mounting seat 3, and the docking block 503 on the built-in frame 502 and the docking groove 504 on the inner side of the mounting seat 3 are on the same plane.

After they are fully connected, the fixed through hole 606 on the connecting seat 501 corresponds to the plug-in positioning groove 405 on the mounting seat 3. The staff drives the two sets of internal thread moving blocks 403 to move in opposite directions on the bidirectional screw rod 402 by operating the drive motor 401. The internal thread moving blocks 403 drive the linkage plate 602 to move, and the linkage The movable plate 602 drives the connecting plate 603 to move toward the middle, and the connecting plate 603 drives the connecting column 604 to move, so that the plug-in positioning rod 404 on the inner side of the connecting column 604 is connected to the plug-in positioning groove 405 through the fixed through-hole 606, until the sealing gasket 605 on one side of the connecting column 604 is fully in contact with the outer wall of the connecting seat 501, thereby ensuring the stability of the connection between the valve controller 2 and the valve body 1. When it is necessary to perform maintenance on the valve controller 2, the staff drives the two sets of internal threaded moving blocks 403 to move outward on the two-way screw rod 402 by operating the drive motor 401, thereby driving the two sets of connecting plates 603 to move outward, so that the plug-in positioning rod 404 extends from the plug-in positioning groove 405 and the fixed through-hole 606. The staff can remove the valve controller 2 from the mounting seat 3 by pulling it for maintenance operations.
