Ball valve upper packing type seat mounting structure

Abstract

This utility model relates to the technical field of ball valve installation devices, and more particularly to a ball valve seat mounting structure. It includes multiple support plates connected to the outer wall of the ball valve body. Each support plate is L-shaped, with a threaded hole at its bottom. A bolt is threaded into the threaded hole. A limiting component is mounted on the support plate, and a fixing component is mounted on the limiting component. By driving the fixing component, the limiting rod rotates to the lower inner side of the connecting block. The distance between the inner top of the connecting block and the top of the support block is equal to the thickness of the top of the limiting rod, thus vertically limiting the top of the limiting rod. Then, the fixing component prevents the limiting rod from rotating, thus preventing it from detaching from the lower part of the connecting block. At this time, the bottom of the limiting rod presses against the top of the bolt, preventing the bolt from loosening due to shaking.

Description

Technical Field

[0001] This utility model relates to the technical field of ball valve mounting devices, specifically to a top-mounted valve seat mounting structure for ball valves. Background Technology

[0002] Ball valves are devices used in oil and natural gas transportation, as well as in industrial pipelines for chemical and nuclear power industries, for distributing and changing the flow direction of media. They consist of a valve body, a ball, a valve seat, and sealing rings. They feature an integrated valve body structure, allowing for rapid online maintenance by installing the valve seat and ball assembly at the top; internal components can be removed for repair without disassembling the pipeline.

[0003] Ball valves are typically mounted and fixed to brackets using bolts. This allows the ball valve to be secured to the bracket, which in turn provides support. However, the conventional method of fixing the ball valve's mounting plate to the bracket simply involves screwing the bolts in. When the ball valve is transporting media, vibrations inevitably occur, causing the bolts to wobble and eventually unscrew. This makes the connection between the ball valve's mounting plate and the bracket unstable. Therefore, a top-mounted valve seat mounting structure is needed to restrict the outward movement of the bolts and prevent them from falling off the mounting plate and bracket.

[0004] This utility model proposes a top-mounted valve seat mounting structure for ball valves to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a top-mounted valve seat installation structure for ball valves.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ball valve seat mounting structure, including multiple support plates (2) connected to the outer side wall of the ball valve body (1), the support plates are L-shaped, the bottom end of the support plates is provided with a screw hole, the screw hole is internally threaded with a bolt, a limiting component is installed on the support plate, and a fixing component is installed on the limiting component; The limiting component includes a support block, a through hole, a limiting rod, and a limiting hole. The support block is connected to the side wall of the support plate. The top of the support block has a through hole, and the limiting rod is slidably inserted into the through hole. The top of the limiting rod has two symmetrically distributed limiting holes.

[0007] In a preferred embodiment of this invention, the perforation is aligned with the screw hole, and the perforation is located above the screw hole.

[0008] As a preferred embodiment of this utility model, the limiting rod is T-shaped.

[0009] As a preferred technical solution of this utility model, the fixing component includes a connecting block, a sliding hole, a bottom hole, a plug rod, and a spring. The top of the support block is connected to two connecting blocks symmetrically distributed about the through hole axis. The top of the connecting block is provided with a sliding hole, and the top of the support block is provided with a bottom hole. A plug rod is slidably connected in the sliding hole, and the top of the plug rod is connected to a spring. The bottom end of the spring is connected to the top of the connecting block.

[0010] In a preferred embodiment of this utility model, the bottom hole is aligned with the sliding hole, the bottom hole is located below the sliding hole, and the insertion rod is T-shaped.

[0011] As a preferred embodiment of this utility model, the connecting block is L-shaped, the distance between the inner top end of the connecting block and the top end of the support block is equal to the thickness of the top end of the limiting rod, the bottom hole and the sliding hole can both be aligned with the limiting hole, and the distance between the two connecting blocks is greater than the top width of the limiting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a driving fixing component to rotate the limiting rod to the lower inner side of the connecting block. By utilizing the fact that the distance between the inner top of the connecting block and the top of the support block is equal to the thickness of the top of the limiting rod, the connecting block is vertically limited to the top of the limiting rod. Then, the fixing component prevents the limiting rod from rotating, thus preventing it from detaching from the bottom of the connecting block. At this time, the bottom end of the limiting rod presses against the top of the bolt, preventing the bolt from loosening outwards due to shaking. Attached Figure Description

[0015] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Example Please refer to Figures 1-7 The present invention provides the following technical solution: a ball valve upper-mounted valve seat mounting structure, including multiple support plates 2 connected to the outer side wall of the ball valve body 1, the support plates 2 are L-shaped, the bottom end of the support plate 2 is provided with a screw hole 3, the screw hole 3 is internally threaded with a bolt 4, a limiting member 5 is installed on the support plate 2, and a fixing member 6 is installed on the limiting member 5. The limiting component 5 includes a support block 501, a through hole 502, a limiting rod 503, and a limiting hole 504. The support block 501 is connected to the side wall of the support plate 2. The top of the support block 501 has a through hole 502. The limiting rod 503 is slidably inserted into the through hole 502. The top of the limiting rod 503 has two symmetrically distributed limiting holes 504. The through hole 502 is aligned with the screw hole 3 and is located above the screw hole 3. The limiting rod 503 is T-shaped.

[0017] After screwing bolt 4 into bolt hole 3 and connecting bolt 4 to mounting hole on bracket, making support plate 2 and bracket integrated, then insert limiting rod 503 into through hole 502, ensuring the short side of the top of limiting rod 503 is parallel to the sidewalls of the two connecting blocks 601, allowing limiting rod 503 to move below the top of connecting block 601. Then, drive fixing member 6 to rotate limiting rod 503 to the inner lower side of connecting block 601, utilizing the connecting block 601's... The distance between the inner top and the top of the support block 501 is equal to the thickness of the top of the limiting rod 503, so that the connecting block 601 vertically limits the top of the limiting rod 503. Then, the fixing part 6 prevents the limiting rod 503 from rotating, so as to avoid the limiting rod 503 from falling off the bottom of the connecting block 601. At this time, the bottom end of the limiting rod 503 presses the top of the bolt 4, so that the tendency of the bolt 4 to be unscrewed outward due to shaking is blocked by the limiting rod 503, thereby preventing the bolt 4 from falling off due to shaking.

[0018] Please refer to Figure 2 and Figure 7 The fixing component 6 includes a connecting block 601, a sliding hole 602, a bottom hole 603, a plug rod 604, and a spring 605. Two connecting blocks 601 symmetrically distributed about the axis of the through hole 502 are connected to the top of the support block 501. The top of the connecting block 601 has a sliding hole 602, and the top of the support block 501 has a bottom hole 603. A plug rod 604 is slidably connected within the sliding hole 602. A spring 605 is connected to the top of the plug rod 604, and the bottom end of the spring 605 is connected to… The top of the connecting block 601 is connected, the bottom hole 603 is aligned with the sliding hole 602, the bottom hole 603 is located below the sliding hole 602, the shape of the insert rod 604 is T-shaped, the shape of the connecting block 601 is L-shaped, the distance between the inner top of the connecting block 601 and the top of the support block 501 is equal to the thickness of the top of the limiting rod 503, both the bottom hole 603 and the sliding hole 602 can be aligned with the limiting hole 504, and the distance between the two connecting blocks 601 is greater than the top width of the limiting rod 503.

[0019] After the limiting rod 503 can be moved into the lower part of the connecting block 601, pull the insertion rod 604. The insertion rod 604 stretches the spring 605, so that the bottom end of the insertion rod 604 can be pulled out from the lower part of the connecting block 601, and the top end of the limiting rod 503 can be rotated into the lower part of the connecting block 601. Rotate the limiting rod 503 so that the limiting hole 504 is aligned with the sliding hole 602 and the bottom hole 603. Then release the insertion rod 604 so that the insertion rod 604 passes through the sliding hole 602, the limiting hole 504 and the bottom hole 603. Using the elastic force of the spring 605, the insertion rod 604 can be stably inserted into the bottom hole 603, thereby restricting the rotation of the top end of the limiting rod 503.

[0020] Please refer to Figure 7 The outer surface of the spring 605 can be coated with protective paint or fitted with an anti-slip sleeve to prevent the spring 605 from being corroded by the external environment. The top of the insertion rod 604 is provided with anti-slip texture to facilitate pulling the insertion rod 604.

[0021] The working principle and usage process of this utility model are as follows: In specific use, after screwing the bolt 4 into the screw hole 3 and connecting the bolt 4 with the mounting hole on the bracket, the support plate 2 and the bracket are connected as one unit. Then, the limiting rod 503 is inserted into the through hole 502, and the short side of the top end of the limiting rod 503 is kept relatively parallel to the side walls of the two connecting blocks 601, so that the limiting rod 503 can be moved below the top end of the connecting block 601. After the limiting rod 503 is moved below the top end of the connecting block 601, the insertion rod 604 is pulled to insert... The rod 604 stretches the spring 605, allowing the bottom end of the insertion rod 604 to be pulled out from the lower inner side of the connecting block 601, so that the top end of the limiting rod 503 can be rotated into the lower inner side of the connecting block 601. The limiting rod 503 is rotated so that the limiting hole 504 is aligned with the sliding hole 602 and the bottom hole 603. Then the insertion rod 604 is released, allowing the insertion rod 604 to pass through the sliding hole 602, the limiting hole 504 and the bottom hole 603. Using the elastic force of the spring 605, the insertion rod 604 can be stably inserted into the bottom hole 603, thereby restricting the rotation of the top end of the limiting rod 503.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
