Description

Technical Field

[0001] This utility model relates to a disassembly and assembly device for a ball valve sealing base and a movable ring, and in particular to a device for separating and reassembling the ball valve sealing base and the movable ring. Background Technology

[0002] Most hydropower stations did not include a design for removing the upstream and downstream sealing rings of ball valves in their initial design phase. During maintenance, removing the sealing rings requires stacking copper sheets and inserting them into the gap between the sealing ring and the fixed ring, gradually moving the sealing ring away from the fixed ring until it is completely removed and detached. This process requires a significant amount of time and manpower. Reinstallation requires symmetrically striking the sealing ring with a sledgehammer to fully embed it into the fixed ring, making it difficult to maintain consistent force at each striking point. This outdated method of removing and reinstalling the sealing rings is difficult to operate, causing numerous inconveniences and safety hazards during unit maintenance. Utility Model Content

[0003] The purpose of this invention is to provide a device for disassembling and assembling the ball valve sealing base and the movable ring. This device improves disassembly and assembly efficiency while minimizing safety hazards.

[0004] The technical solution of this utility model is as follows: A disassembly and assembly device for a ball valve sealing base and a movable ring, comprising a lower support plate, sleeves on both sides of the upper end of the lower support plate, an upper support plate on the upper side of the sleeves, two sets of third screws and one set of first screws arranged parallel to the sleeves between the sleeves, a lifting plate at the lower end of the first screw, a nut installed on the upper support plate at the upper end of the first screw, a connecting seat on the third screw, the connecting seat comprising a connecting plate arranged horizontally and installed on the third screw, a mounting plate arranged vertically between the third screw and the first screw on the upper side of the connecting plate, and a second screw that can rotate relative to the mounting plate and abuts against the lifting plate in the mounting plate.

[0005] In the aforementioned disassembly and assembly device for a ball valve sealing base and a movable ring, the upper support plate is provided with two sets of first mounting holes corresponding to the sleeve, two sets of second mounting holes corresponding to the third screw, and a horizontal through groove corresponding to the first screw.

[0006] In the aforementioned disassembly and assembly device for a ball valve sealing base and a movable ring, the lower support plate is provided with two sets of third mounting holes corresponding to the sleeve and two sets of fourth mounting holes corresponding to the third screw.

[0007] In the aforementioned disassembly and assembly device for a ball valve sealing base and a movable ring, the lifting plate includes a main body, the upper end of which is provided with a connecting hole corresponding to the first screw, and the side of the main body away from the second screw is provided with a top disassembly part.

[0008] In the aforementioned disassembly and assembly device for a ball valve sealing base and a movable ring, the upper end face of the top disassembly part is a horizontal plane, and the lower end face of the top disassembly part is an inclined plane.

[0009] Compared with the prior art, this utility model uses a second screw to drive the lifting plate to move laterally and push it into the gap between the movable ring and the base. Then, the first screw and nut work together to move the lifting plate upward, separating the movable ring from the ball valve sealing base. When installing the movable ring, after the movable ring is connected to the ball valve sealing base, the nut is rotated in the opposite direction to move the lifting plate downward, pressing the movable ring into the sealing base. This makes disassembly and assembly more convenient and safer. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0014] Example 1. A device for disassembling and assembling a ball valve sealing base and a movable ring, configured as follows: Figure 1 As shown, the system includes a lower support plate 1. Sleeves 2 are provided on both sides of the upper end of the lower support plate 1. An upper support plate 3 is provided on the upper side of the sleeves 2. Two sets of third screws 4 and one set of first screws 5 are arranged parallel to the sleeves 2. A lifting plate 10 is provided at the lower end of the first screw 5, and a nut 16 is installed on the upper support plate 3 at the upper end of the first screw 5. A connecting seat is provided on the third screw 4. The connecting seat includes a connecting plate 6 horizontally arranged and installed on the third screw 4. A mounting plate 7 vertically arranged between the third screw 4 and the first screw 5 is provided on the upper side of the connecting plate 6. A second screw 9, which can rotate relative to the mounting plate 7 and abuts against the lifting plate 10, is provided in the mounting plate 7. Further, the sleeves 2 can be composed of a fourth screw fixed on the lower support plate 1 and a sleeve disposed outside the fourth screw.

[0015] The upper support plate 3 is provided with two sets of first mounting holes 11 corresponding to the sleeve 2, two sets of second mounting holes corresponding to the third screw 4, and a horizontal through groove 13 corresponding to the first screw 5.

[0016] The lower support plate 1 is provided with two sets of third mounting holes 14 corresponding to the sleeve 2 and two sets of fourth mounting holes corresponding to the third screw 4. The second mounting holes and the fourth mounting holes are not located in the same area. Figure 1 The section in question is not shown in the diagram.

[0017] The lifting plate 10 includes a main body 19, with a connecting hole 17 at the upper end of the main body 19 corresponding to the first screw 5, and a top dismantling part 18 on the side of the main body 19 away from the second screw 9.

[0018] The upper surface of the top dismantling part 18 is a horizontal plane, and the lower surface of the top dismantling part 18 is an inclined plane.

[0019] The principle of this utility model: This application includes a lower support plate 1, and an upper support plate 3 is provided on the upper side of the lower support plate 1 through two sets of sleeves 2. A first screw 5 is provided between the lower support plate 1 and the upper support plate 3. The first screw 5 can move along the horizontal through groove 13 to realize the lateral position adjustment. When adjusting the lateral position, the second screw 9 rotates relative to the mounting plate 7. The mounting plate 7 is provided with a screw hole corresponding to the second screw 9, thereby changing the extension length of the second screw relative to the mounting plate 7. The end of the second screw 9 abuts against the lifting plate 10, thereby driving the lifting plate and the second screw to move laterally. A nut 16 is provided on the upper side of the upper support plate 3 at the upper end of the first screw 5. By rotating the nut 16, the lifting plate 10 can be moved vertically.

[0020] In use, the connecting plate 6 is attached to the upper side of the base, and the connecting plate 6 has a mating hole corresponding to the third screw. Then, the second screw 9 drives the lifting plate 10 and the first screw 5 to move laterally, so that the top part 18 of the lifting plate 10 is engaged in the gap between the movable ring and the base. The upper end face of the top part 18 is horizontal, and the lower end face of the top part 18 is inclined, thus forming a sharp angle, which is more conducive to insertion into the gap between the movable ring and the base. Furthermore, an external copper sheet can be used to pry open a small gap between the movable ring and the sealing seat, which is sufficient for the tip of the lifting plate to be inserted. Then, the nut 16 is rotated in the direction that the nut is close to the direction of movement of the lifting plate. Since the second screw is pressed against the lifting plate 10 and the end of the lifting plate 10 is engaged in the gap between the movable ring and the base, the lifting plate 10 cannot rotate when the nut 16 is rotated. The nut 16 exerts a downward force on the upper support plate 3, which is more stable. In this way, during the rotation of the nut 16, the lifting plate 10 will move upward, thereby quickly separating the movable ring from the base, making disassembly more convenient. When installing the movable ring, after the movable ring is connected to the ball valve sealing base, rotate the nut in the opposite direction to lower the lifting plate and press the movable ring into the sealing base.

[0021] Example 2. Based on Example 1, in order to improve the contact effect with the movable ring when reinstalling it, this application can remove the third screw 4, the first screw 5, the connecting plate 6, and other components, and remove the sleeve outside the sleeve 2, leaving only the lower support plate 1, the upper support plate 3, the fourth screw, and the adjusting nut set on the fourth screw. By simultaneously rotating the adjusting nuts on the two sets of fourth screws, the upper support plate 3 exerts downward pressure on the movable ring on the lower side, thereby realizing the reinstallation of the movable ring. The structure is more streamlined and the cost is lower.
