Description

A valve stop turning device for anti-surge regulating valve

Technical Field

The invention relates to the technical field of valve stop turning, in particular to a valve stop turning device for an anti-surge regulating valve.

Background Art

When the output pressure of a centrifugal compressor remains constant and the flow rate decreases to a certain value, surge will occur. The anti-surge valve is a device that prevents the centrifugal gas compressor from surging during operation. The stopper of the valve is a structure used for centering and connection, commonly known as the Yin-Yang stopper. The convex stopper is the Yang stopper, and the concave stopper is the Yin stopper. The convex stopper is composed of a protruding short cylinder and an end face, and the concave stopper is composed of a short hole and an end face. The stopper face refers to the end face of the short cylinder and the short hole.

During the production process of the anti-surge control valve, according to the use requirements, among the three valve ports of the anti-surge control valve, the inner and outer diameters of one port are not equal to the inner and outer diameters of the other two ports, and the inner and outer diameters of the other two ports are consistent. Therefore, during use, the existing valve stop turning device can synchronously turn the two valve ports with consistent inner and outer diameters through the turning mechanism. However, when turning multiple valves, since the valves are fixed by clamping, iron filings will accumulate inside the valves due to turning. At the same time, after turning the valves, the turned valves need to be removed before the unturned valves can be installed. Based on this, a valve stop turning device for an anti-surge control valve is now provided, which can eliminate the disadvantages of the existing devices.

During this process, the moving slider 2011 slides along the inner wall of an arc-shaped guide groove 2010 driven by the rotating seat 5. At this time, the connecting slide plate 2012 drives the second rack 209 to slide and rise along the inner wall of the rotating seat 5 through the connecting shaft under the drive of the moving slider 2011. At the same time, the first gear ring 207 drives the rotating disk 201 to rotate through the first connecting rotating cylinder 202 under the meshing drive of the second rack 209. At this time, the rotating disk 201 rotates along the inner wall of the rotating seat 5 through the limiting rotating ring 206. At the same time, the valve is turned over by the two flexible clamps 302 under the drive of the rotating disk 201 until the moving slider 2011 moves to one end where the two arc-shaped guide grooves 2010 are connected to each other, so that the positions of the two rotating disks 201 can be swapped and the valve can be turned over.

At the same time, the moving slider 2011 at one end of the other rotating disk 201 can make the other rotating disk 201 rotate synchronously. In this process, the two lifting and rotating plates 402 at one end of the one rotating disk 201 rotate to the inside of the rotating disk 201 with the synchronous rotating rod 403 as the axis under the action of gravity, and the synchronous rotating rod 403 is driven to rotate by the limiting slider, so as to automatically store the two lifting and rotating plates 402.

When the two rotating disks 201 are swapped, one lifting and rotating plate 402 is manually pulled to rotate and reset with the synchronous rotating rod 403 as the axis. At the same time, the synchronous rotating rod 403 can drive the other lifting and rotating plate 402 to rotate synchronously through the cooperation of the limiting slide groove and the limiting slider. Then, the two ports of the valve can be turned by the turning component 7, and the above operation can be repeated. In this way, during the turning of one valve, the next valve can be clamped by the two flexible clamps 302 on the other rotating disk 201. When the turning of one valve is completed, the above operation is repeated, thereby effectively improving the turning efficiency of the valve.

The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
