Technical Field
[0001] This utility model relates to the field of ball valve technology, specifically to an easy-to-assemble ball valve. Background Technology
[0002] A ball valve is a common type of on / off valve that controls the flow of fluid or regulates its flow rate by rotating a ball with a through hole. Its core component is a ball with a central hole; when the hole is aligned with the pipe, fluid flows through; after rotating 90°, the hole becomes perpendicular to the pipe, and the valve closes.
[0003] For example, a one-piece ball valve with Chinese patent publication number CN218063488U includes a valve body, a valve stem, a ball, a valve seat, an inlet channel, and an outlet channel; a valve seat mounting base is provided in the inlet channel, and an abutment fixing block is provided on the right side of the valve seat mounting base; a filter plate is provided in the inlet channel; and auxiliary fixing components are fixedly provided at the upper and lower ends of the inner wall of the inlet channel. The auxiliary fixing components include a fixing base, a support bottom rod, a push block, a compression spring, a limit groove, a limit spring, a limit ball, and a welding block.
[0004] Existing ball valves are inconvenient to assemble because they require external support during installation and are not easy to rotate on the support. Therefore, an improved device is needed to address these issues. Utility Model Content

Detailed Implementation
[0018] 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.
[0019] Please see Figure 1-3This utility model provides an embodiment of an easy-to-assemble ball valve, including an alignment device 2. Support devices 1 are rotatably sleeved at both ends of the outer ring of the alignment device 2. The support device 1 includes a first retaining ring 4, a plastic ring 5, a second retaining ring 6, a rotating bolt 7, a first positioning sleeve 8, a rotating base ring 9, a limiting rod 10, a synchronizing rod 11, and an extension bracket 12. The first retaining ring 4 is symmetrically fixedly installed at the bottom of one end of the extension bracket 12. The second retaining ring 6 is rotatably installed at the bottom end of the first retaining ring 4. The plastic ring 5 is fixedly installed on the inner rings of the first retaining ring 4 and the second retaining ring 6. The rotating bolt 7 is rotatably installed at the top of one end of the second retaining ring 6. The first positioning sleeve 8 is threaded onto the outer ring of the rotating bolt 7. The rotating base ring 9 is fixedly installed at the bottom of the extension bracket 12 away from the first retaining ring 4. The limiting rod 10 is symmetrically slidably inserted into the interior of the rotating base ring 9. The synchronizing rod 11 is fixedly installed between the two limiting rods 10.
[0020] The alignment device 2 includes a second positioning sleeve 13 and a ball valve 14. The second positioning sleeve 13 is fixedly installed at both ends of the outer ring of the ball valve 14. By limiting the ball valve 14, it can support the ball valve 14 to rotate between two rotating base rings 9.
[0021] The rotating base ring 9 is rotatably sleeved on the outer ring of the second positioning sleeve 13, which can prevent the ball valve 14 from shifting.
[0022] The rotating base ring 9 has round holes at both ends to restrict the sliding of the insertion rod 10 inside the rotating base ring 9.
[0023] The rotating base ring 9 has a sleeve hole in its inner center to facilitate the installation of the ball valve 14.
[0024] There is a gap between the bottom end of the synchronizing rod 11 and the second positioning sleeve 13 to prevent interference between the synchronizing rod 11 and the second positioning sleeve 13 when the synchronizing rod 11 drives the limiting rod 10 to move.
[0025] Working principle: In use, first move the first retaining ring 4 until it contacts the top of the outer ring of the outer pipe 3, so that the rotating base ring 9 can support the flange on the ball valve 14 and the flange on the outer pipe 3 to be horizontally aligned. At this time, the second retaining ring 6 can be rotated upward until it merges with the first retaining ring 4, so that the first retaining ring 4 and the second retaining ring 6 can be fitted onto the outer ring of the outer pipe 3. Then, rotate the rotating bolt 7 upward to a vertical position, and then screw the first positioning sleeve 8 until the first positioning sleeve 8 is tightened with the first retaining ring 4, so that the first retaining ring 4 and the second retaining ring 6 can be fixed on the outer pipe. On the outer ring of pipe 3, plastic rings 5 are fixedly installed on the inner walls of the first retaining ring 4 and the second retaining ring 6, thereby increasing the contact friction between the first retaining ring 4 and the second retaining ring 6 and the outer pipe 3. Then, the ball valve 14 rotates inside the rotating base ring 9 through the second positioning sleeve 13, so that after the first retaining ring 4 is fixed, the rotating base ring 9 can support the rotation of the ball valve 14. Then, the ball valve 14 is rotated until the handle on the ball valve 14 is rotated vertically upward. Then, the flange hole of the ball valve 14 is aligned with the flange hole of the outer pipe 3, and the limiting rod 10 is moved closer to the first retaining ring 3. One end of the retaining ring 4 moves, allowing the limiting rod 10 to be inserted into the holes of the flanges inside the ball valve 14 and the outer pipe 3, ensuring alignment of the holes on the two flanges. Then, external bolts can be passed through the holes on the two flanges, and nuts can be installed onto the bolts to secure the two flanges. At this point, the limiting rod 10 can be moved away from the end of the first retaining ring 4, allowing it to be removed from the flanges inside the outer pipe 3 and the ball valve 14. This facilitates the installation of the remaining bolts and nuts, completing the installation of the ball valve 14 between the two outer pipes 3. In operation, this device, by screwing the first positioning sleeve 8 and the first retaining ring 4 which is in a combined state, can restrict the first retaining ring 4 and the second retaining ring 6 on the outer ring of the outer pipe 3, so that the rotating base ring 9 can support the rotation of the ball valve 14. When the ball valve 14 is aligned with the flange on the outer pipe 3, the limiting rod 10 can be inserted into the round hole inside the two flanges, so that the fasteners of the two flanges can be installed easily. Furthermore, the limiting rod 10 can be removed from the flanges to install the remaining fasteners, thus completing the quick assembly and docking of the ball valve 14 with the outer pipe 3.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
