Description

Technical Field

[0001] The utility model belongs to the technical field of flange ball valves, in particular to a flange ball valve which is easy to replace. Background Art

[0002] A flanged ball valve is a commonly used control valve, primarily consisting of a valve body, stem, valve core, ball, and gasket. Its operating principle is to control the flow of fluid by rotating the ball. When the valve is closed, the ball fits tightly against the gasket, preventing fluid from passing through the pipe. When the valve is open, the ball rotates along the opening in the valve body, allowing fluid to flow smoothly through the pipe.

[0003] When using a flanged ball valve, connect the two ends of the flanged ball valve to the pipe where the ball valve is installed through the flange. After the installation is completed, push the control rod to adjust the rotation of the ball inside the ball valve to achieve the opening and closing of the pipeline. When the sealing adjustment effect of the ball valve is abnormal and needs to be repaired or replaced, just remove the connecting bolts at the flange.

[0004] However, when installing a flanged ball valve, if the pipes on both sides are located in a narrow space, it is inconvenient to align the flanges with the pipes when connecting them through the flanges, making installation more inconvenient. In addition, during use, the ball valve will cause the joints of the flanges at both ends to be deformed due to its own weight, resulting in a decrease in the sealing effect of the ball valve and leakage.

DETAILED DESCRIPTION

[0025] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0026] like Figure 1-3As shown, the utility model provides a technical solution: a flange ball valve that is easy to replace, including a pipe body 1, a ball 4 is rotatably provided inside the pipe body 1, a through hole is provided on the outer surface of the ball 4, a control rod 5 is provided on the top of the pipe body 1, a flange 6 is fixedly connected to one side of the pipe body 1, and a plurality of mounting holes are provided on the outer surface of the flange 6. A supporting structure 2 is installed on the outer surface of the pipe body 1 with the help of a convenient structure 3, and the supporting structure 2 includes an L-shaped block 21, and a slider 22 is slidably connected to the inner wall of the L-shaped block 21. A slide groove 24 is provided on one side of the L-shaped block 21, and a screw 25 is fixedly connected to one side of the slider 22. The outer surface of the screw 25 slides on the inner wall of the slide groove 24, and a threaded ring 26 is threadedly connected to the outer surface of the screw 25. A spring 23 is provided on one side of the slider 22, and the upper and lower ends of the spring 23 are fixedly connected to one side of the slider 22 and one side of the L-shaped block 21 respectively. By setting the slider 22, When the flange ball valve is connected to the pipeline, the supporting structure 2 is installed on one side of the pipe body 1 through the convenient structure 3. When the pipe body 1 is placed between the two pipes and connected to the pipe through the flange 6, one side of the slider 22 will rest on the wall or ground of the pipe installation position, and the position of the pipe body 1 is moved so that the flanges 6 at both ends are aligned with the positions of the pipes on both sides. At the same time, the slider 22 will slide on the inner wall of the L-shaped block 21 and compress the spring 23 on one side of the slider 22, and the screw 25 will slide on the inner wall of the slide groove 24. After the positions are aligned, the threaded ring 26 is rotated to move the threaded ring 26 on the outer surface of the screw 25 toward one side of the L-shaped block 21, and one side of the threaded ring 26 is pressed against one side of the L-shaped block 21 to fix the position between the slider 22 and the L-shaped block 21. The slider 22 and the L-shaped block 21 support the bottom of the pipe body 1, making it convenient to connect the pipe body 1 to the pipes on both sides through the flange 6.

[0027] Specifically, such as Figure 2-4 As shown, the outer surface of the threaded ring 26 is fixedly connected with a plurality of protrusions 27, and the protrusions 27 are distributed in a circle on the outer surface of the threaded ring 26. Holding the protrusions 27 on the outer surface of the threaded ring 26 can more conveniently push the threaded ring 26 to rotate without slipping. A gasket 28 is fixedly connected to one side of the threaded ring 26. The gasket 28 is made of rubber material. When the threaded ring 26 is provided with a rubber gasket 28 and pressed against one side of the L-shaped block 21 to fix the position of the slider 22, it is more stable and less likely to slide accidentally.

[0028] Specifically, such as Figure 2-4As shown, the end of the screw 25 away from the slider 22 is fixedly connected to a round block 29, and the diameter of the round block 29 is larger than the diameter of the screw 25. By setting the round block 29, the movement range of the threaded ring 26 on the outer surface of the screw 25 can be limited, and the threaded ring 26 can be prevented from falling off and dropping the screw 25 when moving on the surface of the screw 25 as much as possible. A round rod 210 is fixedly connected to one side of the slider 22, and the outer surface of the round rod 210 slides on one side of the L-shaped block 21. The round rod 210 is located inside the spring 23. When the spring 23 is compressed, it will move on the outside of the round rod 210. The round rod 210 can reinforce the internal shape of the spring 23, and avoid lateral deformation of the spring 23 when it is compressed to affect normal use as much as possible.

[0029] Specifically, such as Figure 1-3 As shown, the convenient structure 3 includes a slot block 31, one side of the slot block 31 is fixedly connected to one side of the tube body 1, a slot 32 is provided on one side of the slot block 31, two first through holes 33 are provided on the outer surface of the slot block 31, and two second through holes 34 are provided on the outer surface of the L-shaped block 21. Bolts 35 are slidably inserted into the inner wall of the first through hole 33. When installing the support structure 2, one end of the L-shaped block 21 is inserted into the slot 32 on the outer surface of the slot block 31, and the L-shaped block 21 is pushed to move inside the slot 32 until the second through hole 34 on the outer surface is formed. The through hole 34 is aligned with the first through hole 33 on the outer surface of the slot block 31, and then the bolt 35 is inserted through the first through hole 33 into the second through hole 34, and the bolt 35 is turned so that the bolt 35 is threadedly connected with the inner wall of the second through hole 34, and the L-shaped block 21 is fixed inside the slot block 31 and below the tube body 1. The bolt 35 is turned so that the bolt 35 is disengaged from the inside of the second through hole 34 and then the L-shaped block 21 is pulled out from the inside of the slot 32. The support structure 2 can be disassembled and replaced, thereby improving the convenience of using the support structure 2.

[0030] Specifically, such as Figure 2-3 As shown, two elastic ropes 36 are fixedly connected to the outer surface of the slot block 31, and the ends of the two elastic ropes 36 away from the slot block 31 are rotatably connected to one end of the two bolts 35 respectively. By setting the elastic ropes 36, the bolts 35 can always be fixed on one side of the slot block 31, which is convenient for taking and using when disassembling the support structure 2 and preventing the bolts 35 from falling and being lost.

[0031] The working principle of this utility model is:

[0032] S1. When connecting the flange ball valve to the pipeline, you can first insert one end of the L-shaped block 21 into the slot 32 on the outer surface of the slot block 31, push the L-shaped block 21 to move inside the slot 32 until the second through hole 34 on the outer surface is aligned with the first through hole 33 on the outer surface of the slot block 31, and then insert the two bolts 35 fixed to the outer surface of the slot block 31 by elastic ropes 36 through the two first through holes 33 and into the second through holes 34 respectively, turn the bolts 35 so that the bolts 35 are threadedly connected to the inner wall of the second through holes 34, and install the support structure 2 on one side of the pipe body 1.

[0033] S2. When the pipe body 1 is placed between the two pipes and connected to the pipes through the flange 6, one side of the slider 22 will be against the wall or the ground where the pipes are installed. Then the position of the pipe body 1 is moved so that the flanges 6 at both ends are aligned with the positions of the pipes on both sides. At the same time, the slider 22 will slide on the inner wall of the L-shaped block 21 and compress the spring 23 on one side of the slider 22. The screw 25 will slide on the inner wall of the slide groove 24. After the positions are aligned, the threaded ring 26 is rotated so that the threaded ring 26 is on the outer surface of the screw 25 and on one side of the L-shaped block 21. Move sideways, press the side of the threaded ring 26 with the rubber gasket 28 against the side of the L-shaped block 21, fix the position between the slider 22 and the L-shaped block 21, support the bottom of the pipe body 1 through the slider 22 and the L-shaped block 21, and then use the bolts 35 and nuts connecting the flange 6 and the pipeline to connect the flange 6 at both ends of the pipe body 1 to the flange at the pipeline. When using the flange ball valve, push the control rod 5 to rotate to adjust the angle of the ball 4 inside the pipe body 1 to close or open the inside of the pipe body 1.
