Description

Technical Field

[0001] This utility model relates to the field of valve fittings technology, and in particular to a valve support anti-rotation structure. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications. When installing some valves on pipelines, brackets are needed to position the valve body to ensure that it does not shake.

[0003] Existing valve supports typically utilize support rods and other structures as the overall support structure for the valve, providing a certain degree of support. Arc-shaped clamps on both sides are used to hold the valve in place, ensuring overall stability between the valve and the support structure. However, a gap exists between the arc-shaped clamps and the valve, causing the valve to wobble and rotate within this gap during use, resulting in poor stability and room for improvement. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a valve support anti-rotation structure.

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

[0006] A valve support anti-rotation structure includes a base plate and a valve body. Mounting bolts are threaded to the four corners of the upper surface of the base plate. A support rod is fixedly connected to the upper surface of the base plate, and a positioning component is fixedly connected to the top of the support rod. The positioning component includes an arc-shaped positioning frame with an arc-shaped groove on its upper surface. Two circular retaining rings are fixedly connected to the surface of the valve body, and two locking plates are fixedly connected to the surface of the circular retaining rings. Each locking plate has a circular hole on its upper surface. A positioning screw is fixedly connected to the surface of the circular retaining rings, and the circular retaining rings overlap with the inner wall of the arc-shaped groove. Two circular through holes are opened on the lower surface of the arc-shaped positioning frame, and the surface of the positioning screw is threaded with... The locking nut and the arc-shaped positioning frame have cavities on both sides corresponding to the two circular retaining rings. Circular drive shafts are rotatably connected to the corresponding positions on both sides of the arc-shaped positioning frame. A vertical bevel gear is fixedly connected to the end of the circular drive shaft away from the side of the arc-shaped positioning frame. A lead screw is rotatably connected to the inner bottom wall of the cavity. A transverse bevel gear is fixedly connected to the surface of the lead screw. A movable plate is slidably connected to the inner wall of the cavity. An anti-rotation screw is fixedly connected to the upper surface of the movable plate. An anti-rotation nut is threaded onto the surface of the anti-rotation screw. A limit groove is opened in the inner wall of the cavity. A limit rod is fixedly connected to the inner bottom wall of the limit groove. A limit block is slidably connected to the inner wall of the limit groove.

[0007] Preferably, the positioning screw is adapted to the circular through hole, and the upper surface of the locking nut overlaps with the lower surface of the arc-shaped positioning frame.

[0008] Preferably, the circular drive shaft extends into the cavity, and the vertical bevel gear meshes with the horizontal bevel gear. Rotating the circular drive shaft can drive the vertical bevel gear to rotate, thereby driving the horizontal bevel gear and the lead screw to rotate.

[0009] Preferably, the movable plate is threadedly connected to the lead screw, and the upper surface of the arc-shaped positioning frame is provided with four circular holes that are adapted to the anti-rotation screws. After the lead screw rotates, it can drive the movable plate to rise, thereby driving the four anti-rotation screws to pass through the circular holes and extend to the upper position of the arc-shaped positioning frame.

[0010] Preferably, the upper surface of the limiting block is provided with a limiting hole, and the limiting block is slidably connected to the surface of the limiting rod through the limiting hole. The limiting block is limited by the limiting rod and will not rotate.

[0011] Preferably, the side of the limiting block away from the inner wall of the limiting groove is fixedly connected to the movable plate. During the upward movement, the movable plate can drive the limiting block to slide upward on the surface of the limiting rod, thereby ensuring that the movable plate will not rotate with the lead screw, resulting in higher stability.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By setting up the positioning components, the connection strength between the valve body and the arc-shaped positioning frame can be increased by using the positioning screw, locking nut, anti-rotation screw, and anti-rotation nut. This ensures that the valve body will not have any offset or rotation issues with the arc-shaped positioning frame during use. Furthermore, the valve body is locked to the inner wall of the arc-shaped groove by the circular retaining ring, leaving no gaps. Therefore, the valve body will not wobble due to the nut loosening during use, resulting in better stability of the valve body during use.

[0014] 2. By setting the limit rod and limit block, the position of the movable plate can be locked during the up and down movement, ensuring the overall stability of the movable plate and preventing the movable plate from shifting after being driven by the screw, thus affecting the rising angle of the anti-rotation screw.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1, referring to Figure 1 , Figure 2 and Figure 3A valve support anti-rotation structure includes a base plate 1 and a valve body 2. The four corners of the upper surface of the base plate 1 are threaded with mounting bolts 3. A support rod 4 is fixedly connected to the upper surface of the base plate 1. A positioning component is fixedly connected to the top of the support rod 4. The positioning component includes an arc-shaped positioning frame 5. An arc-shaped groove is opened on the upper surface of the arc-shaped positioning frame 5. Two circular retaining rings 6 are fixedly connected to the surface of the valve body 2. Two locking plates 7 are fixedly connected to the surface of the circular retaining rings 6. A circular hole is opened on the upper surface of the two locking plates 7.

[0021] A positioning screw 8 is fixedly connected to the surface of the circular retaining ring 6. The circular retaining ring 6 overlaps with the inner wall of the arc-shaped retaining groove. Two circular through holes are opened on the lower surface of the arc-shaped positioning frame 5. The positioning screw 8 is adapted to the circular through holes. A locking nut 9 is threadedly connected to the surface of the positioning screw 8. The upper surface of the locking nut 9 overlaps with the lower surface of the arc-shaped positioning frame 5. Cavities are opened on the left and right sides of the arc-shaped positioning frame 5 at positions corresponding to the two circular retaining rings 6. Circular transmission shafts 10 are rotatably connected to the left and right sides of the arc-shaped positioning frame 5 at positions corresponding to the cavities. A vertical bevel gear 11 is fixedly connected to one end of the circular transmission shaft 10 away from the side of the arc-shaped positioning frame 5.

[0022] After the positioning screw 8 passes through the circular through hole, the locking nut 9 can lock the position of the positioning screw 8, thereby ensuring the connection strength between the valve body 2 and the arc-shaped positioning frame 5, and ensuring that the valve body 2 will not detach from the arc-shaped positioning frame 5 during use.

[0023] A lead screw 12 is rotatably connected to the inner bottom wall of the cavity. A transverse bevel gear 13 is fixedly connected to the surface of the lead screw 12. A circular transmission shaft 10 extends into the cavity, and a vertical bevel gear 11 meshes with the transverse bevel gear 13. A movable plate 14 is slidably connected to the inner wall of the cavity. The movable plate 14 is threadedly connected to the lead screw 12. An anti-rotation screw 15 is fixedly connected to the upper surface of the movable plate 14. Four circular holes adapted to the anti-rotation screw 15 are opened on the upper surface of the arc-shaped positioning frame 5. An anti-rotation nut 16 is threadedly connected to the surface of the anti-rotation screw 15.

[0024] Rotating the circular drive shaft 10 can drive the horizontal bevel gear 13 to rotate through the vertical bevel gear 11, thereby driving the movable plate 14 to rise through the lead screw 12. The movable plate 14 then drives the anti-rotation screw 15 through the circular hole and the circular hole on the locking plate 7. At this time, the anti-rotation screw 15 is locked by the anti-rotation nut 16, which locks the position between the valve body 2 and the arc-shaped positioning frame 5, so that the valve body 2 will not rotate or deviate from the arc-shaped positioning frame 5 during use, resulting in higher stability.

[0025] A limiting groove is provided on the inner wall of the cavity. A limiting rod 17 is fixedly connected to the inner bottom wall of the limiting groove. A limiting block 18 is slidably connected to the inner wall of the limiting groove. A limiting hole is provided on the upper surface of the limiting block 18. The limiting block 18 is slidably connected to the surface of the limiting rod 17 through the limiting hole. The side of the limiting block 18 away from the inner wall of the limiting groove is fixedly connected to the movable plate 14.

[0026] During the upward movement, the movable plate 14 is blocked and limited by the limiting block 18 and the limiting rod 17, and will not rotate with the lead screw 12. Therefore, the movable plate 14 will drive the anti-rotation screw 15 to rise steadily.

[0027] Working principle: First, the valve body 2 with a circular retaining ring 6 is inserted into the inner wall of the arc-shaped groove of the arc-shaped positioning frame 5. The two positioning screws 8 on the surface of the circular retaining ring 6 are passed through the circular through hole, and the positioning screws 8 are locked with two locking nuts 9. This ensures the connection strength between the valve body 2 and the arc-shaped positioning frame 5, and ensures that the valve body 2 will not detach from the arc-shaped positioning frame 5 during use, thus improving stability. At the same time, four locking plates 7 are placed on top of the arc-shaped positioning frame 5. Then, the four circular drive shafts 10 are rotated, causing the circular drive shafts 10 to drive the vertical bevel gear 11 to rotate. The transverse bevel gear 13 drives the lead screw 12 to rotate. After the lead screw 12 rotates, it can drive the movable plate 14 to rise in the cavity. After the movable plate 14 rises, it drives the anti-rotation screw 15 to pass through the circular hole and reach the position above the locking plate 7. At this time, four anti-rotation nuts 16 are inserted into the surface of the anti-rotation screw 15. The circular retaining ring 6 is used to strengthen the position between the valve body 2 and the arc-shaped positioning frame 5, ensuring that the valve body 2 will not rotate during use. The locking effect of the valve body 2 is good, thereby improving the stability of the valve body 2 during use.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
