Description

Technical Field

[0001] This utility model relates to the field of horizontal lift valve technology, specifically to a valve shaft concentricity adjustment device for a horizontal lift valve. Background Technology

[0002] The concentricity of the valve shaft in a horizontal lift valve directly affects the smoothness and accuracy of its opening and closing actions. If the valve shaft concentricity deviates, the valve may fail to open or close completely, affecting fluid flow control and consequently impacting the normal operation of the entire system.

[0003] However, the existing valve shaft cannot be easily adjusted, resulting in high requirements for equipment machining precision.

[0004] To address this issue, we proposed a valve shaft concentricity adjustment device for horizontal lift valves. Utility Model Content

[0005] The purpose of this invention is to provide a valve shaft concentricity adjustment device for a horizontal lifting valve, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve shaft concentricity adjustment device for a horizontal lifting valve, comprising:

[0007] Valve plate;

[0008] Valve shaft, outer wall, and valve plate are installed together;

[0009] Both the lift valve adjusting fixing plate and the lift valve adjusting plate are installed on the outside of the valve shaft;

[0010] Both the fixed bearing and the ball bearing are installed on the lifting valve adjusting plate, and the fixed bearing and the ball bearing are used to fix the valve shaft;

[0011] The adjusting bolt is connected to the adjusting fixing plate of the lifting valve.

[0012] Preferably, a cylinder is fixedly mounted on the end of the valve shaft.

[0013] Preferably, there are two ball bearings, which are symmetrically distributed on both sides of the fixed bearing.

[0014] Preferably, there are two adjusting bolts, which are symmetrically distributed around the centerline of the lifting valve adjusting fixing plate.

[0015] This utility model provides a valve shaft concentricity adjustment device for a horizontal lift valve. This valve shaft concentricity adjustment device for a horizontal lift valve has the following beneficial effects:

[0016] The valve shaft concentricity adjustment device of this horizontal lifting valve uses two ball bearings and one fixed bearing to position the valve shaft fixing column, which can flexibly adjust the height of both ends of the valve shaft, thereby effectively reducing the requirements of the equipment for machining accuracy.

[0020] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0021] A preferred embodiment of the valve shaft concentricity adjustment device for the horizontal lift valve provided by this utility model is, for example... Figures 1 to 2 As shown: The valve shaft concentricity adjustment device for a horizontal lift valve includes:

[0022] Valve plate 3;

[0023] The valve shaft 2 is mounted on the outer wall of the valve plate 3, and a cylinder 1 is fixedly mounted on the end of the valve shaft 2.

[0024] Both the lift valve adjusting fixing plate 4 and the lift valve adjusting plate 6 are installed on the outside of the valve shaft 2;

[0025] The fixed bearing 7 and the ball bearing 8 are both installed on the lifting valve adjusting plate 6. The fixed bearing 7 and the ball bearing 8 are used to fix the valve shaft 2. There are two ball bearings 8, which are symmetrically distributed on both sides of the fixed bearing 7. This can control the height of the two ends of the valve shaft 2 and reduce the machining accuracy requirements of the equipment.

[0026] Two adjusting bolts 5 are connected to the lifting valve adjusting fixing plate 4. The two adjusting bolts 5 are symmetrically distributed around the center line of the lifting valve adjusting fixing plate 4. The height position of the lifting valve adjusting fixing plate 4 can be adjusted by the two adjusting bolts 5, and the lifting valve adjusting plate 6 can be adjusted up or down.

[0027] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
