Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a ball valve relay with a hydraulic locking device. Background Technology

[0002] A ball valve actuator is a hydraulic drive device specifically designed to control the opening and closing of ball valves. Its core function is to convert hydraulic energy into mechanical rotational force, driving the ball to complete a 90° rotation through a dual-cylinder hydraulic system. It is widely used in pipeline control systems in hydropower stations, petrochemical plants, and other fields. In traditional designs, the actuator directly pushes the ball valve stem through the reciprocating motion of the hydraulic cylinder piston to open and close the valve. However, this design has certain drawbacks in actual operation. Existing devices require a dual-cylinder hydraulic system to open and close the ball valve, resulting in high operating costs, relatively complex maintenance, and low maintenance efficiency. Furthermore, during installation, the distance between the handle and the pipeline varies for different ball valves, meaning that a specific device can only be used with a specific ball valve, making leveling difficult and limiting its application. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a ball valve relay with a hydraulic locking device, comprising a first connector for connecting a handle and a second connector for connecting a pipe. A driving component for driving the first connector to rotate is fixedly connected to one side of the second connector. The driving component includes a guide portion, a slide plate is slidably connected inside the guide portion, and a hydraulic cylinder is fixedly connected to the side of the guide portion away from the slide plate. A side plate is fixedly connected between the telescopic end of the hydraulic cylinder and the slide plate. A first rotating rod is rotatably connected to the side of the slide plate away from the guide portion, and the sliding direction of the slide plate is the same as the extension direction of the pipe.

[0013] 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.

[0014] like Figures 1-5 As shown, the ball valve relay with hydraulic locking device includes a first connector 1 for connecting the handle and a second connector 2 for connecting the pipe. A drive 3 for driving the first connector 1 to rotate is fixedly connected to one side of the second connector 2. The drive 3 includes a guide portion, a slide plate 31 is slidably connected inside the guide portion, and a hydraulic cylinder 36 is fixedly connected to the side of the guide portion away from the slide plate 31. A side plate 37 is fixedly connected between the telescopic end of the hydraulic cylinder 36 and the slide plate 31. A first rotating rod 32 is rotatably connected to the side of the slide plate 31 away from the guide portion, and the sliding direction of the slide plate 31 is the same as the extension direction of the pipe. A second rotating rod 33 is rotatably connected inside the first rotating rod 32, and the free end of the second rotating rod 33 is rotatably connected to the first connector 1.

[0015] With the above technical solution, before using the device, the first connecting piece 1 is connected to the handle, and the second connecting piece 2 is connected to the pipeline. When it is necessary to drive the handle to rotate, the second connecting piece 2 supports the guide part, and the hydraulic cylinder 36 works, thereby driving the slide plate 31 to slide back and forth along the guide part. When the slide plate 31 slides, it pushes the first rotating rod 32, which in turn pushes the second rotating rod 33, thereby driving the first connecting piece 1 to rotate continuously, so that the first connecting piece 1 drives the handle to rotate, thereby opening or closing the ball valve. After the ball valve is opened or closed to a certain extent, the hydraulic cylinder 36 stops working, thereby maintaining the angle of the slide plate 31. The slide plate 31 fixes the angle of the first rotating rod 32 and the second rotating rod 33, thereby fixing the angle of the handle and maintaining the opening or closing degree of the ball valve.

[0016] Specifically, in one embodiment, regarding the second connector 2 described above, as follows: Figure 1 and Figure 3 As shown, the second connector 2 includes a connecting part sleeved on the pipe, a slot 22 is provided on the connecting part, a plug 27 is slidably connected inside the slot 22, and a second limiting rod 28 is screwed onto one side of the connecting part. The free end of the second limiting rod 28 extends into the slot 22 to clamp the plug 27, and one side of the plug 27 is fixedly connected to the guide part.

[0017] In this embodiment, when it is necessary to fix the second connector 2, the connecting part is sleeved on the pipe. After the connecting part is installed, the insert 27 is inserted into the slot 22 on the connecting part. The insert 27 is pulled to move. When the insert 27 moves, it will drive the guide part to move synchronously, thereby leveling the position of the guide part. After the position of the guide part is adjusted, the second limiting rod 28 is screwed to the connecting part until the free end of the second limiting rod 28 moves into the slot 22 to clamp the insert 27. After the position of the insert 27 is fixed, the guide part is supported by the insert 27, so that the device can be adjusted according to the distance between the handle and the pipe, so that the handle can be rotated smoothly, improving the convenience of the device and expanding the scope of application of the device.

[0018] In addition, regarding how the connecting part is installed onto the pipe in this utility model, such as... Figure 1 and Figure 3 As shown, the connecting part includes an arc-shaped frame 21. Two nylon straps 23 are symmetrically fixedly connected to one side of the arc-shaped frame 21. Two slots 22 are opened on the arc-shaped frame 21, and the two nylon straps 23 are located between the two slots 22. A connector 24 is fixedly connected to the free end of one of the nylon straps 23. A through hole 25 is opened on the connector 24, and a movable first limiting rod 26 is screwed onto one side of the connector 24. The free end of the first limiting rod 26 extends into the interior of the through hole 25.

[0019] In this embodiment, the arc-shaped frame 21 is placed on one side of the pipe, and the two nylon straps 23 are pulled to fit tightly against the outer wall of the pipe. One of the nylon straps 23 is inserted into the connector 24 on the other nylon strap 23, and the nylon strap 23 passes through the through hole 25 on the connector 24. The first limiting rod 26 is screwed into the connector 24 until the first limiting rod 26 is tightly against the nylon strap 23, thereby fixing the two nylon straps 23 together and fixing the arc-shaped frame 21 to the pipe. The arc-shaped frame 21 supports the insert 27.

[0020] Specifically, in one embodiment, regarding the first connecting member 1 described above, as follows: Figures 1-2 As shown, the first connector 1 includes a connector frame 11, a movable connector rod 13 is screwed onto the connector frame 11, and a connector groove 12 for inserting a handle is provided on the connector frame 11. A pressure plate 14 is fixedly connected to the free end of the connector rod 13, and the pressure plate 14 is located inside the connector groove 12.

[0021] In this embodiment, the connecting frame 11 is fitted onto the handle through the connecting groove 12, and then the connecting rod 13 on the connecting frame 11 is rotated to move the connecting rod 13 relative to the connecting frame 11. When the connecting rod 13 moves, it will drive the pressure plate 14 to move synchronously. The pressure plate 14 clamps the handle, thereby fixing the connecting frame 11 to the handle. The second rotating rod 33 pushes the connecting frame 11, causing the connecting frame 11 to drive the handle to rotate.

[0022] Furthermore, in this utility model, regarding the aforementioned guiding portion, as follows: Figure 1 , Figure 4 and Figure 5 As shown, the guide portion includes a track plate 34, with a groove 35 formed inside the track plate 34 along its own length direction. A slide plate 31 is slidably connected inside the groove 35. A hydraulic cylinder 36 is fixedly connected to the side of the track plate 34 away from the groove 35. A guide groove 38 matching the side plate 37 is provided on the track plate 34.

[0023] In this embodiment, after the insert 27 is connected to the arc frame 21, the insert 27 supports the track plate 34, and the track plate 34 supports the hydraulic cylinder 36. When the hydraulic cylinder 36 is working, the hydraulic cylinder 36 drives the side plate 37 to move. The guide groove 38 restricts the direction of movement of the side plate 37. The side plate 37 drives the slide plate 31 to slide along the track plate 34, thereby driving the second rotating rod 33 and the first rotating rod 32 to reciprocate.

[0024] To ensure a more secure fixation of the curved frame 21, such as... Figure 1 and Figure 3 As shown, the arc-shaped frame 21 is recessed on one side facing the pipe to form an arc-shaped groove that fits the pipe, and the arc-shaped groove is located between two nylon strips 23.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
