Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve technology, specifically a manual emergency mechanism for a hydraulic valve. Background Technology

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressurized oil of a pressure regulating valve and is usually used in combination with a solenoid pressure regulating valve. It can be used to remotely control the on / off of oil, gas and water pipeline systems in hydropower stations. It is a component used in hydraulic transmission to control the pressure, flow and direction of liquids.

[0003] Most existing manual emergency mechanisms for hydraulic valves control the separation and contact between the valve core and the conical valve seat by pushing a handle, thereby controlling the flow of fluid and closing the hydraulic valve. However, the exposed handle is too large and is easy to accidentally push, causing the hydraulic valve to be closed during operation. Therefore, we propose a manual emergency mechanism for hydraulic valves. Utility Model Content

[0004] To solve the above technical problems, this application provides a manual emergency mechanism for a hydraulic valve, including a valve pipeline, a ball cylinder rotatably connected to the inner cavity of the valve pipeline, a first rotating column fixedly connected to the upper end of the ball cylinder, a second rotating column slidably connected to the upper end of the first rotating column, the second rotating column being provided with a sliding element, a limit column fixedly connected to the lower end of the second rotating column, and a fixed shell slidably connected to the outer side of the lower end of the second rotating column, the outer side of the fixed shell being provided with a fixing element;

[0005] The lower end of the central circular column of the first rotating column contacts the lower end of the fixed shell. A limiting groove is provided at the left end of the fixed shell, and the limiting column is slidably fitted within the limiting groove. An elastic element is provided between the lower end of the second rotating column and the lower end of the fixed shell.

[0006] Preferably, the sliding member includes a groove formed in the inner cavity of the second rotating column, and sliding grooves are formed on both the left and right sides of the groove. Sliding plates are fixedly connected to both the left and right sides of the first rotating column, and the sliding plates are slidably engaged within the sliding grooves.

[0007] Preferably, the fastener includes a fixing cylinder that is fixedly connected to the lower outer side of the fixing shell, and the lower end of the fixing cylinder is fixedly connected to the upper end of the valve pipe.

[0008] Preferably, the elastic element includes a spring provided on the lower end surface of the second rotating column and the lower end surface of the fixed shell, and the upper end of the spring is connected and fixed to the lower end surface of the rotating column.

[0009] Preferably, a washer is fixedly connected to the lower end of the spring, and the washer is slidably connected to the inner surface of the lower end of the fixed shell.

[0010] Preferably, the upper surface of the limiting groove is provided with a magnet.

[0011] Preferably, the limiting groove has a U-shaped structure, and the connection of the limiting groove has an arc-shaped structure.

[0012] This utility model has at least the following beneficial effects:

[0013] Firstly, this utility model involves pressing down on the second rotating column to compress the spring, while simultaneously moving the limiting column downwards within the limiting groove until the limiting groove contacts the lower surface of the fixed shell. Then, the second rotating column is rotated along the trajectory of the limiting groove, synchronously driving the first rotating column to rotate, causing the ball cylinder to rotate synchronously until the limiting column moves to the other end of the limiting groove. The ball cylinder will then turn to the side without the hole. After releasing the pressure, the spring returns to its original shape, and the limiting column moves upwards to the upper end of the limiting groove, thereby closing the valve pipeline. This method requires pressing down on the second rotating column and then rotating it to close or open the valve pipeline, making it difficult for workers to close or open the valve pipeline if they accidentally touch the second rotating column.

[0014] Secondly, this utility model connects and fixes the upper end of the spring to the lower end surface of the rotating column. When the limiting column moves to the other end of the lower end surface of the limiting groove, the second rotating column is released and the spring restores its original deformation, allowing the limiting column to move directly to the upper end of the limiting groove. At the same time, under the action of the spring force, the limiting column is not easy to move to the lower end of the limiting groove, thereby fixing the ball cylinder and preventing the valve pipeline from being easily closed or opened.

[0021] 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.

[0022] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a manual emergency mechanism for a hydraulic valve, including a valve pipe 1, a ball cylinder 2 rotatably connected to the inner cavity of the valve pipe 1, a first rotating column 3 fixedly connected to the upper end of the ball cylinder 2, a second rotating column 4 slidably connected to the upper end of the first rotating column 3, the second rotating column 4 being provided with a sliding element, a limit column 5 fixedly connected to the lower end of the second rotating column 4, and a fixed shell 6 slidably connected to the outer side of the lower end of the second rotating column 4, with a fixing element provided on the outer side of the fixed shell 6;

[0023] The lower end of the central circular column of the first rotating column 3 contacts the lower end of the fixed shell 6. A limiting groove 7 is opened at the left end of the fixed shell 6, and the limiting column 5 slides in the limiting groove 7. An elastic element is provided between the lower end of the second rotating column 4 and the lower end of the fixed shell 6. In actual use, the second rotating column 4 is pressed down first to compress the spring 8. At the same time, the limiting column 5 moves down in the limiting groove 7 until the limiting groove 7 contacts the lower end surface of the fixed shell 6. Then, the second rotating column 4 is rotated along the trajectory of the limiting groove 7, which synchronously drives the first rotating column 3 to rotate, so that the ball cylinder 2 rotates synchronously until the limiting column 5 moves to the other end of the limiting groove 7. The ball cylinder 2 will turn to the side without the hole. Then, the hand is released, and the spring 8 returns to its original shape. The limiting column 5 will move up to the upper end of the limiting groove 7, thereby closing the valve pipeline 1.

[0024] Furthermore, the sliding component includes a groove 9 formed in the inner cavity of the second rotating column 4, and sliding grooves 10 are formed on both the left and right sides of the groove 9. Sliding plates 11 are fixedly connected to both the left and right sides of the first rotating column 3. The sliding plates 11 are slidably engaged in the sliding grooves 10. During the upward or downward movement of the second rotating column 4, the sliding plates 11 slide in the sliding grooves 10, making the upward and downward movement of the second rotating column 4 more stable.

[0025] Furthermore, the fixing component includes a fixing cylinder 12 fixedly connected to the lower outer side of the fixing shell 6. The lower end of the fixing cylinder 12 is fixedly connected to the upper end of the valve pipe 1. The second rotating column 4 can move up and down through the fixing shell 6.

[0026] Furthermore, the elastic element includes a spring 8 provided on the lower end surface of the second rotating column 4 and the lower end surface of the fixed shell 6. The upper end of the spring 8 is connected and fixed to the lower end surface of the rotating column 4. When the limiting column 5 moves to the other end of the lower end surface of the limiting groove 7, the second rotating column 4 is released and the spring 8 restores its original deformation, allowing the limiting column 5 to move directly to the upper end of the limiting groove 7. At the same time, under the action of the elastic force of the spring 8, the limiting column 5 is not easy to move to the lower end of the limiting groove 7, thereby fixing the ball cylinder 2 and preventing the valve pipeline 1 from being easily closed or opened.

[0027] Furthermore, a washer 13 is fixedly connected to the lower end of the spring 8. The washer 13 is slidably connected to the inner surface of the lower end of the fixed shell 6 to avoid wear caused by contact between the spring 8 and the fixed shell 6, thereby extending the service life of the spring 8.

[0028] In summary: First, press down on the second rotating column 4 to compress the spring 8. At the same time, the limiting column 5 moves downward within the limiting groove 7 until the limiting groove 7 contacts the lower surface of the fixed shell 6. Then, rotate the second rotating column 4 along the trajectory of the limiting groove 7, synchronously driving the first rotating column 3 to rotate, causing the ball cylinder 2 to rotate synchronously until the limiting column 5 moves to the other end of the limiting groove 7. The ball cylinder 2 will then turn to the side without the hole. Then, release the pressure to allow the spring 8 to return to its original shape. The limiting column 5 will then move upward to the upper end of the limiting groove 7, thereby closing the valve pipeline 1.

[0029] Example 2: Please refer to Figure 5 Based on Embodiment 1, this utility model provides magnets 14 on the upper surface of the limiting groove 7. When the limiting post 5 moves to the lower two ends of the limiting groove 7, the second rotating post 4 is released, and the limiting post 5 is attracted by the magnets 14, so that the limiting post 5 reaches the top of the limiting groove 7, thereby fixing the ball cylinder 2 and preventing the valve pipeline 1 from being easily closed or opened.

[0030] Furthermore, the limiting groove 7 has a U-shaped structure, and the connection of the limiting groove 7 has an arc-shaped structure, which makes the movement of the limiting post 5 within the limiting groove 7 more stable and smooth.
