Description

Technical Field

[0001] This utility model relates to the field of valve manufacturing technology, specifically to a ball valve with high-efficiency protection function. Background Technology

[0002] A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the ball valve axis. It can also be used for fluid regulation and control. Among them, the hard-seal V-type ball valve has a strong shearing force between the V-shaped ball core and the metal valve seat with hard alloy overlay, making it particularly suitable for media containing fibers, small solid particles, etc.

[0003] For example, a ball valve with publication number CN219911930U belongs to the field of valve manufacturing technology. It solves the problems of existing ball valves lacking a protective structure, leaving the valve handle exposed and easily damaged after installation, leading to valve control failure. Furthermore, it lacks a filtering function, requiring external filtering components for filtration while the valve is conveying media, resulting in complex installation steps and difficult disassembly and cleaning. This ball valve includes a ball valve body. A flange is bolted to the left side of the ball valve body. A protective cover is fixedly installed on the top of the ball valve body. A cover plate is rotatably connected to the rear side of the top of the protective cover via a shaft. A positioning component is fixedly installed on the top of the front surface of the protective cover. A flange is bolted to the right side of the ball valve body. A flange is bolted to the right side of flange two. A flange is bolted to the right side of flange two. A filter assembly is connected to the right side of flange three. The filter assembly includes a fixed housing, and a flange is connected to the right side of the fixed housing.

[0004] When using a ball valve with high-efficiency protection, the drive wheel is protected by a protective cover. However, when the protective cover protects the drive wheel, the gap between the drive wheel and the protective cover is relatively small when the operator needs to push the drive wheel to close the ball valve body. This makes it difficult for the operator to drive the drive wheel and reduces the effectiveness of the device.

[0005] Therefore, we propose a ball valve with high-efficiency protection function to solve the problems mentioned above. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9 This utility model provides a technical solution: a ball valve with high-efficiency protection function, including a ball valve body 1, flanges 2 fixedly installed on both sides of the ball valve body 1, a protective cover 3 installed on the top of the ball valve body 1, a cover plate 4 hinged to the rear side of the protective cover 3, a drive wheel 5 provided on the top of the ball valve body 1, the drive wheel 5 located in the inner cavity of the protective cover 3, an adjustment component 6 provided on the drive wheel 5, and a limit component 7 installed on the adjustment component 6;

[0030] The adjustment assembly 6 includes a rotating shaft 61 mounted on the drive wheel 5 and a drive rod A62 fixedly sleeved on the outer periphery of the rotating shaft 61. A limiting ring 63 is fixedly sleeved on the outer periphery of the drive rod A62 near its end. A drive rod B64 is provided on the top of the drive wheel 5 near one side. Both the drive rod A62 and the drive rod B64 are made of iron. By setting the drive rod A62 and the drive rod B64, the drive wheel 5 can be easily pushed, making it convenient to rotate the drive wheel 5 in a narrow space.

[0031] The drive rod A62 has an external thread 621 near its end on its outer periphery, and the drive rod B64 has a threaded groove 641 at its end. The cross-sectional diameter of the drive rod A62 is smaller than that of the drive rod B64. The drive rod B64 can be threaded onto the outer periphery of the drive rod A62 to reduce the pushing force required by the operator.

[0032] The top of the protective cover 3 is provided with arc-shaped grooves 31 near both sides. Magnets D32 are fixedly installed at the bottom of the inner cavity of the arc-shaped grooves 31 near the rear side. A support block 33 is fixedly installed at the rear side of the protective cover 3 near the top. The support block 33 is set to prevent the cover from opening too large and affecting subsequent normal use.

[0033] Magnets C41 are fixedly installed on both sides of the bottom of the cover plate 4, and magnets C41 and adjacent magnets D32 are magnetically attracted to each other. By setting magnets C41 and D32, the cover plate 4 can be stably placed on the top of the protective cover 4.

[0034] A placement slot B52 is provided on the top of the drive wheel 5 near one side, and a placement slot A51 is provided on the top of the drive wheel 5 near the other side. The two ends of the rotating shaft 61 are rotatably connected to the inner cavity sidewall of the placement slot A51. A magnet A54 is fixedly installed on the bottom of the inner cavity of the placement slot A51 near one side, and the magnet A54 is magnetically attracted to the drive rod A62. A magnet B53 is fixedly installed on the bottom of the inner cavity of the placement slot B52, and the magnet B53 is magnetically attracted to the drive rod B64. The drive rod A62 and the drive rod B64 can be stored by setting up placement slots A51 and B52.

[0035] In this embodiment: the drive wheel 5 can be protected by the protective cover 3 and the cover plate 4 to prevent damage to the drive wheel 5 and valve control failure. When it is necessary to control the ball valve body 1, the cover plate 4 is flipped over to expose the drive wheel 5. The drive rod A62 is flipped over and made to be in a vertical state. The drive rod B64 located in the placement groove B52 is taken out and threaded to the outer periphery of the drive rod A62. The drive wheel 5 can be driven by the drive rod B64, reducing the force applied by the operator to push the drive wheel 5.

[0036] Example 2: Please refer to Figure 5-8 The limiting component 7 includes a limiting plate 71 and a limiting hole 72 opened on the front side of the limiting plate 71 near the middle position. The limiting plate 71 is fixedly sleeved on the outer periphery of the rotating shaft 61. A cylinder 73 is provided on the front side of the limiting plate 71 near one side. A connecting block 74 is fixedly installed at the front end of the cylinder 73. A toggle block 75 is fixedly installed on the top of the connecting block 74. A telescopic column 76 is fixedly installed at the middle position of the front side of the connecting block 74. The front end of the telescopic column 76 is fixedly connected to the inner cavity side wall of the placement groove A51. By setting the cylinder 73 to be inserted into the inner cavity of the limiting hole 72, the driving rod A62 can be limited when it is in a vertical state, preventing it from swaying left and right when the driving wheel 5 is pushed by the driving rod B64, which would affect the efficiency of opening the ball valve body.

[0037] A spring 761 is movably sleeved on the outer periphery of the telescopic column 76, and the front and rear ends of the spring 761 are fixedly connected to the inner cavity side wall of the placement groove A51 and the connecting block 74, respectively. By setting the spring 761, the cylinder 73 can be stably inserted into the inner cavity of the limiting hole 72.

[0038] In this embodiment: when the drive rod A62 is flipped, the limiting hole 72 can be rotated. When the drive rod A62 is in a vertical state, the cylinder 73 can be inserted into the inner cavity of the limiting hole 72 under the elastic force of the spring 761, and the limiting plate 71 is limited, so that the drive rod A62 is always in a vertical state. When it is necessary to release the limiting plate 71, the drive rod B64 threaded to the outer periphery of the drive rod A62 is removed. Then, the actuating block 75 is pushed forward to move the connecting block 74 fixed on the actuating block 75 forward, so that the telescopic column 76 and the spring 761 are squeezed, and the cylinder 73 fixed on the connecting block 74 is moved away from the inner cavity of the adjacent limiting hole 72. At this time, the drive rod A62 can be flipped back to the initial state.

[0039] Working principle: The protective cover 3 and cover plate 4 protect the drive wheel 5 from external damage, preventing valve control malfunction. When the ball valve body 1 needs to be controlled, the cover plate 4 is flipped to expose the drive wheel 5. By flipping the drive rod A62 and placing it in a vertical position, the limiting hole 72 rotates. When the drive rod A62 is in a vertical position, the cylinder 73 is inserted into the inner cavity of the limiting hole 72 under the elastic force of the spring 761, limiting the limiting plate 71 and ensuring that the drive rod A62 is always in a vertical position. In a vertical position, remove the drive rod B64 located in the placement slot B52 and thread it onto the outer periphery of the drive rod A62. The drive wheel 5 can be driven by the drive rod B64. When it is necessary to release the limit on the limiting plate 71, remove the drive rod B64 threaded onto the outer periphery of the drive rod A62. Then push the actuating block 75 forward to move the connecting block 74 fixed on the actuating block 75 forward, so that the telescopic column 76 and the spring 761 are compressed, and the cylinder 73 fixed on the connecting block 74 can be moved away from the inner cavity of the adjacent limiting hole 72. At this time, the drive rod A62 can be flipped back to the initial state.
