Description

Technical Field

[0001] This utility model relates to the field of high-pressure ball valve technology, specifically a high-pressure ball valve that is easy to disassemble and maintain quickly. Background Technology

[0002] A high-pressure ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the axis of the valve stem. Used in hydraulic machinery, hydraulic switches, natural gas, etc., high-pressure ball valves were first introduced in the 1950s. With the rapid development of science and technology and continuous improvements in production processes and product structures, they have quickly become a major type of valve in just 40 years.

[0003] In existing technologies, high-pressure ball valves are generally used in a variety of scenarios. In the petrochemical industry, they can be installed in crude oil extraction and transportation pipelines to withstand high pressure and ensure efficient crude oil transportation. They can also be used for pipeline control of various chemical raw materials to prevent leakage of corrosive media. In the natural gas industry, whether it is a long-distance main pipeline or a city gas distribution system, high-pressure ball valves can accurately regulate gas pressure and flow to ensure stable gas supply. In the power industry, whether it is the steam circulation system of thermal power generation or the start-up and shutdown control of water turbines in hydropower generation, high-pressure ball valves are indispensable for controlling the on / off state and flow of the medium.

[0004] However, during the use of high-pressure ball valves, the internal structure will wear down over time due to continuous use. When maintaining the internal structure, the high-pressure ball valve must first be disassembled. During disassembly, because there are multiple bolts on the high-pressure ball valve, the disassembly work is tedious and time-consuming. Operators may need to use various sizes of tools to unscrew the bolts one by one. If the bolts are rusty or the tightening force is too great due to long-term high-pressure environment, the bolts may strip or break, further increasing the difficulty of disassembly and even damaging the connecting parts of the high-pressure ball valve. Therefore, we propose a high-pressure ball valve that is easy to disassemble and maintain quickly. Utility Model Content

[0010] In some embodiments, a side plate is provided on one side of the extrusion plate, and one side of the extrusion plate is fixedly connected to one end of the side plate. The inner wall of one side of the side plate is slidably connected to the outer side of the limiting rod. An insertion rod is provided on the inner wall of the limiting rod, and the inner wall of the limiting rod is slidably engaged with the outer side of the bottom end of the insertion rod.

[0011] In some embodiments, the outer side of the insertion rod is slidably connected to the inner wall of the concave rod, and a connecting rod is provided on the inner side of the top end of the concave rod, and one end of the connecting rod is fixedly connected to the inner side of the top end of the concave rod.

[0015] 1. Insert the L-bar on the back plate into the insert rod. At this time, when the back plate is pushed a short distance, the bottom end of the L-bar is located on the bottom side of the connecting rod. Then, when an upward external force is applied to the back plate, the insert rod will disengage from the limiting rod, thereby releasing the position restriction of the extrusion plate. At this time, the extrusion plate is reset, and the spring inside the locking rod will release energy to push the locking rod back, thereby causing the high-pressure ball valve one and high-pressure ball valve two to disconnect the structural connection. This process of breaking the structural connection between the two does not require complicated tools and cumbersome operating procedures, greatly shortening the disassembly time.

[0016] 2. By pushing the limiting rod into the concave rod, the insert rod is then inserted downwards from the top side of the concave rod, allowing it to enter the limiting rod and fix its position. This ensures that the extrusion plate remains stationary after movement, guaranteeing that the locking rod is stably positioned within the convex rod and maintaining the structural stability of the connection between high-pressure ball valve one and high-pressure ball valve two.

[0025] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a high-pressure ball valve that is easy to disassemble and maintain quickly, including a quick-release mechanism 1. An indicator mechanism 2 is provided on one side of the quick-release mechanism 1. The quick-release mechanism 1 includes a protruding rod 13, and a concave rod 14 is provided on the outer side of the protruding rod 13. The outer side of the protruding rod 13 is slidably connected to the inner side of the concave rod 14.

A pressing plate 18 is provided at the top end of the locking rod 15. The top of the 5th rod contacts the bottom side of the extrusion plate 18. A guide rod 19 is provided on the inner wall of the extrusion plate 18. The inner wall of the extrusion plate 18 and the outer side of the guide rod 19 are slidably connected. One end of the guide rod 19 is fixedly connected to one side of the concave rod 14. A spring piece 16 is provided on the inner wall of the locking rod 15. The inner wall of the locking rod 15 is fixedly connected to the top of the spring piece 16. An inner plate 17 is provided at the bottom of the spring piece 16. The bottom of the spring piece 16 is fixedly connected to the top side of the inner plate 17. One end of the inner plate 17 is fixedly connected to the inner wall of the concave rod 14. A side plate 115 is provided on one side of the extrusion plate 18. One side of 8 is fixedly connected to one end of side plate 115. The inner wall of one side of side plate 115 is slidably connected to the outer side of limiting rod 110. The inner wall of limiting rod 110 is provided with insert rod 111. The inner wall of limiting rod 110 is slidably engaged with the outer bottom end of insert rod 111. The outer side of insert rod 111 is slidably connected to the inner wall of concave rod 14. The inner side of the top end of concave rod 14 is provided with connecting rod 112. The inner side of the top end of concave rod 14 is fixedly connected to one end of connecting rod 112. The outer side of connecting rod 112 is provided with L rod 113. The outer side of connecting rod 112 is connected to L rod 113. The bottom inner side of rod 113 is in contact with the back plate 114 at the top of L rod 113. The top of L rod 113 is fixedly connected to the inner side of back plate 114. The outer side of one end of limit rod 110 is rotatably connected to the inner wall of concave rod 14. A high-pressure ball valve 11 is provided on one side of concave rod 14. One side of concave rod 14 is fixedly connected to one side of high-pressure ball valve 11. A high-pressure ball valve 2 12 is provided at one end of high-pressure ball valve 11. One end of high-pressure ball valve 11 and one end of high-pressure ball valve 2 12 are correspondingly matched. One side of high-pressure ball valve 2 12 is fixedly connected to one side of protruding rod 13.

[0026] This type of high-pressure ball valve, which is easy to disassemble and maintain, is designed with two components: a high-pressure ball valve 11 and a high-pressure ball valve 212. When the two are combined, they form a single unit. A concave rod 14 is designed on one side of the high-pressure ball valve 11, and a convex rod 13 is designed on one side of the high-pressure ball valve 212. During the combination of the two components, the convex rod 13 slides along the path of the concave rod 14. After sliding to a certain position, a pressing plate 18 is designed on one side of the concave rod 14. One end of the pressing plate 18 is inclined. Therefore, during the sliding process, the pressing plate 18 exerts downward pressure on the locking rod 15 in the concave rod 14 using its inclined surface. This causes the locking rod 15 to move from its original position. After moving, the locking rod 15 enters the convex rod 13, thus creating a structural connection between the high-pressure ball valve 11 and the high-pressure ball valve 212, while maintaining stability after the connection.

[0027] A side plate 115 is designed on one side of the extrusion plate 18, and a limit rod 110 is slidably connected through the inner wall of the side plate 115. By pushing the limit rod 110 into the concave rod 14, the insertion rod 111 is inserted downward from the top side of the concave rod 14, so that it enters the limit rod 110 to fix the position of the limit rod 110. This can keep the position of the extrusion plate 18 stationary after it is moved, and ensure that the locking rod 15 can be stably placed in the protruding rod 13. This maintains the stability of the structural connection between the high-pressure ball valve 11 and the high-pressure ball valve 12, and prevents the locking rod 15 from loosening due to the movement of the extrusion plate 18 under high-pressure environment and other working conditions, thereby avoiding the connection failure between the high-pressure ball valve 11 and the high-pressure ball valve 12.

[0028] When separating high-pressure ball valve 11 and high-pressure ball valve 12, the L-rod 113 on the back plate 114 is inserted into the insert rod 111. At this time, when the back plate 114 is pushed a short distance, the bottom end of the L-rod 113 is located on the bottom side of the connecting rod 112. Then, when an upward external force is applied to the back plate 114, the insert rod 111 will disengage from the limiting rod 110, thereby releasing the position restriction of the pressing plate 18. At this time, the pressing plate 18 is reset, and the spring 16 inside the locking rod 15 will release energy to push the locking rod 15 back, thereby making the high-pressure ball valve 12 more stable. The disconnection of the high-pressure ball valve 11 and the high-pressure ball valve 2 12 efficiently separates them. When the high-pressure ball valve needs to be disassembled for maintenance, the operator can easily release the position restriction of the pressing plate 18 by using the L-rod on the back plate 114 and applying external force to the back plate 114, thereby resetting the locking rod 15 and breaking the structural connection between the two. This process does not require complicated tools or cumbersome procedures, greatly shortening the disassembly time and improving the efficiency of maintenance work.

[0029] Example 2: Please refer to Figures 2-4The indicating mechanism 2 includes a finger rod 21 with a finger rod 22 at one end. The finger rod 21 and the finger rod 22 are rotatably corresponding. One side of the finger rod 22 is fixedly connected to one side of the concave rod 14. A limit rod 110 is provided on one side of the finger rod 21. One side of the finger rod 21 is fixedly connected to one side of the limit rod 110.

[0030] A first finger rod 21 is designed on one side of the limiting rod 110, and a second finger rod 22 is designed on one side of the recessed rod 14. In order to allow the insertion rod 111 to accurately enter the limiting rod 110, when the limiting rod 110 enters the recessed rod 14, by aligning the first finger rod 21 with the second finger rod 22, the hole of the limiting rod 110 can be made to align with the insertion rod 111 perpendicularly. This allows the insertion rod 111 to be quickly and accurately inserted into the limiting rod 110, greatly improving the efficiency and accuracy of installation. It avoids the insertion rod 111 being difficult to align with the hole of the limiting rod 110 due to blind operation, reducing possible errors and time waste during installation. At the same time, this method of determining the position by aligning the finger rods provides clear reference and guidance for the operator during installation, reducing the difficulty of operation.

[0031] Please see Figures 1-5 The protruding rod 13 slides along the path of the concave rod 14. After sliding to a certain position, since a pressing plate 18 is designed on one side of the concave rod 14, and one end of the pressing plate 18 is inclined, the pressing plate 18 exerts downward pressure on the locking rod 15 in the concave rod 14 during the sliding process. This causes the locking rod 15 to move from its original position. After moving, the locking rod 15 will enter the protruding rod 13, thereby creating a structural connection between the high-pressure ball valve 11 and the high-pressure ball valve 12. The limiting rod 110 is pushed into the concave rod 14. At this time, the insert rod 111 is inserted downward from the top side of the concave rod 14, so that it enters the limiting rod 110 and fixes the position of the limiting rod 110. This can fix the pressing plate 13. 8. Keep the position after the movement still to ensure that the locking rod 15 can be stably placed in the protruding rod 13, maintaining the stability of the structural connection between the high-pressure ball valve 11 and the high-pressure ball valve 2 12. Insert the L rod 113 on the back plate 114 into the insert rod 111. At this time, when the back plate 114 is pushed short distance, the bottom end of the L rod 113 is located on the bottom side of the connecting rod 112. Then, when an upward external force is applied to the back plate 114, the insert rod 111 will disengage from the limiting rod 110, thereby releasing the position restriction of the pressing plate 18. At this time, the pressing plate 18 is reset, and the spring 16 inside the locking rod 15 will release energy to push the locking rod 15 back, thereby causing the high-pressure ball valve 11 and the high-pressure ball valve 2 12 to disconnect the structural connection.

[0032] A first finger rod 21 is designed on one side of the limiting rod 110, and a second finger rod 22 is designed on one side of the concave rod 14. In order to allow the insertion rod 111 to accurately enter the limiting rod 110, when the limiting rod 110 enters the concave rod 14, by aligning the first finger rod 21 with the second finger rod 22, the hole of the limiting rod 110 can be made to be perpendicular to the insertion rod 111. This allows the insertion rod 111 to be quickly and accurately inserted into the limiting rod 110, greatly improving the efficiency and accuracy of installation.
