[0019] 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.
[0020] Please see Figures 1-4 This utility model provides a technical solution: a high-temperature and high-pressure integrated self-sealing ball valve, including a ball valve 1, a control ball 2 rotatably mounted inside the ball valve 1, the control ball 2 rotates so that the connection of the control ball 2 faces both sides of the ball valve 1, realizing the opening of the ball valve 1, an inner rotating shaft 3 is fixedly welded to the upper part of the control ball 2, an outer rotating shaft 13 is rotatably mounted inside the upper side of the ball valve 1, the outer rotating shaft 13 has a lifting groove 4 inside, a rotating cover 5 is slidably mounted on the outer side of the upper part of the inner rotating shaft 3, the rotating cover 5 is slidably mounted inside the lifting groove 4, a first embedding groove 6 is opened on the outer side of the upper part of the inner rotating shaft 3, a first embedding block 7 that matches the first embedding groove 6 is fixedly welded inside the rotating cover 5, the inner rotating shaft 3 can be rotated by rotating the rotating cover 5, a second embedding block 9 is fixedly welded to both sides of the upper part of the rotating cover 5, a second embedding groove 8 that matches the second embedding block 9 is opened inside the outer rotating shaft 13, the inner rotating shaft 3 can be rotated by rotating the rotating cover 5. The outer rotating shaft 13 can drive the rotating cover 5 to rotate. A first fixing plate 14 is fixedly welded to the upper part of the outer rotating shaft 13. A threaded rod 15 is installed inside the first fixing plate 14. A lifting plate 16 is rotatably installed at the lower part of the threaded rod 15. The lifting plate 16 is slidably installed on the outside of the outer rotating shaft 13. A toothed ring 17 is fixedly welded to the lower part of the lifting plate 16. A toothed groove 18 that matches the toothed ring 17 is opened on the upper part of the ball valve 1. By rotating the threaded rod 15, the lifting plate 16 is pushed to slide along the outside of the outer rotating shaft 13, so that the toothed ring 17 is inserted into the toothed groove 18, thereby fixing the rotation of the outer rotating shaft 13 and fixing the opening angle of the ball valve 1. By pulling out the rotating cover 5 along the lifting groove 4, the second embedded block 9 is disengaged from the second embedded groove 8, thereby releasing the linkage between the rotating cover 5 and the outer rotating shaft 13. The rotating cover 5 can be rotated to directly control the inner rotating shaft 3, which facilitates the quick locking of the ball 2.
[0021] A first spring 10 is fixedly welded between the inside of the rotating cover 5 and the inner rotating shaft 3. The first spring 10 pushes the rotating cover 5, allowing it to quickly rise out of the lifting groove 4 and facilitating rotation. An inner limiting rod 12 is fitted on the upper inner side of the first spring 10 and is fixedly welded to the upper inner wall of the rotating cover 5. An outer limiting ring 11 is fitted on the lower outer side of the first spring 10 and is fixedly welded to the upper part of the inner rotating shaft 3 to prevent the first spring 10 from deforming after compression. A rotating rod 19 is rotatably connected to the upper part of the first fixing plate 14. A cover 21 is fixedly welded to the upper part of the rotating rod 19. A torsion spring 20 is fixedly welded between the cover 21 and the first fixing plate 14 and is fitted onto the rotating rod 19. On the outside, the torsion spring 20 drives the cover 21 to rotate, ensuring that the cover 21 covers the upper part of the rotating cover 5 under normal conditions, preventing the rotating cover 5 from disengaging from the lifting groove 4; a locking rod 23 is slidably installed inside the other end of the cover 21, and a second fixing plate 24 is fixedly welded to the upper part of the locking rod 23. The upper part of the first fixing plate 14 has a locking hole 22 that matches the locking rod 23. The locking rod 23 is inserted into the locking hole 22 to prevent accidental contact with the cover 21; a second spring 25 is fixedly welded between the second fixing plate 24 and the first fixing plate 14. The second spring 25 is sleeved on the outside of the locking rod 23. The second spring 25 pulls the second fixing plate 24, causing the locking rod 23 to move downward, which facilitates quick control of the up and down movement of the locking rod 23.
[0022] Working principle: In use, the first fixing plate 14 drives the outer rotating shaft 13 to rotate, the outer rotating shaft 13 drives the rotating cover 5 to rotate, and the rotating cover 5 drives the inner rotating shaft 3 to rotate, thereby adjusting the rotation angle of the control ball 2. By rotating the threaded rod 15, the lifting plate 16 is pushed to slide along the outside of the outer rotating shaft 13, so that the toothed ring 17 is inserted into the toothed groove 18, thereby fixing the rotation of the outer rotating shaft 13 and fixing the opening angle of the ball valve 1. When it is necessary to quickly control the control ball 2, the second fixing plate 24 is pulled upward, the locking rod 23 is disengaged from the locking hole 22, and the second fixing plate 24 rotates the cover 21. The first spring 10 pushes the rotating cover 5, which allows the rotating cover 5 to quickly rise out of the lifting groove 4, so that the second embedded block 9 is disengaged from the second embedded groove 8, thereby releasing the linkage between the rotating cover 5 and the outer rotating shaft 13. The rotating cover 5 can be rotated to directly control the inner rotating shaft 3, which facilitates the quick locking of the control ball 2.
