Description

Technical Field

[0001] This utility model relates to the field of turbine butterfly valve technology, and in particular to a wafer-type turbine butterfly valve. Background Technology

[0002] The worm gear wafer type soft seal butterfly valve has a simple structure, small size, and light weight, consisting of only a few parts; it can be quickly opened and closed with just a 90° rotation, making it easy to operate. At the same time, this valve has good fluid control characteristics. When the flange butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, thus it has good flow control characteristics.

[0003] Existing technologies, such as the utility model patent with publication number CN219453008U, disclose a turbine-driven wafer-type butterfly valve. This patent uses a base plate, with a valve body positioned at the top of the positioning plate. A worm gear is meshed with the front end of the gear, and movable plates are slidably connected to both sides of the outer diameter of the slide rod. A second fixing ring is fixedly connected to the middle of the outer diameter of the two connecting shafts, and a fixing bolt is threaded through and threaded to the top of the front end of the two second fixing rings. This utility model device solves the problems of existing turbine-driven wafer-type butterfly valves, which are inconvenient to install and prone to misalignment and leakage between the valve body and the connecting pipe during installation. Moreover, since the worm gear butterfly valve is driven by a worm, the lack of lubrication for the worm and worm during use reduces the valve's service life.

[0004] In daily operation, during the use of the equipment, there is a problem that the handle may be accidentally activated due to the equipment being installed on the pipeline, causing the handle to rotate and thus affecting the equipment's operating status. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the handle can be rotated arbitrarily, thus altering the movement state of the equipment. This invention proposes a wafer-type turbine butterfly valve.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wafer-type turbine butterfly valve, comprising a main body, a connecting plate, a housing, a rotating handle, and a limiting device. The connecting plate is fixedly connected to the upper surface of the main body, and the housing is fixedly connected to the upper surface of the connecting plate. A rotating handle is provided on the side of the housing, and the limiting device is provided on the side of the housing. The limiting device includes a limiting groove and a sliding plate. The limiting groove is formed on the surface of the rotating handle, and the sliding plate is formed on the surface of the rotating plate. A positioning rod is fixedly connected to the side of the housing, and a limiting rod is fixedly connected to one end of the sliding plate. The limiting rod is engaged with the inner wall of the limiting groove. A sliding hole is formed on the surface of the sliding plate, and the positioning rod is slidably connected to the inner wall of the sliding hole.

[0007] Furthermore, a sliding rod is fixedly connected to the inner wall of the sliding hole, and the sliding rod is slidably connected to the inner wall of the positioning rod. By setting the sliding rod, the sliding plate can be limited to move, reducing the likelihood of wobbling when the sliding plate moves during use, which would make it difficult for the sliding plate to move smoothly.

[0008] Furthermore, a slot is provided at one end of the positioning rod, and a spring rod is fixedly connected to the surface of the slide plate. The spring rod is provided to facilitate the limiting of the slide plate.

[0009] Furthermore, a first spring is sleeved and connected to the surface of the slide rod. The two ends of the first spring are fixedly connected to the inside of the slide hole and the surface of the positioning rod, respectively. The first spring is provided to facilitate the application of a restoring force to the slide plate.

[0010] Furthermore, a fixing device is provided on the side of the main body. The fixing device includes a limiting plate and a pull plate. The limiting plate is fixedly connected to the side of the main body, and the pull plate is slidably connected to the surface of the limiting plate. A positioning post is fixedly connected to the side of the main body, and the positioning post is slidably connected to the inner wall of the pull plate. A pull handle is fixedly connected to the surface of the pull plate. By setting the limiting plate, the pull plate can be limited in movement, reducing the likelihood of the pull plate shaking during use and making it difficult for the fixing plate to move smoothly.

[0011] Furthermore, a second spring is sleeved and connected to the surface of the positioning post. The two ends of the second spring are fixedly connected to the surface of the pull plate and one end of the positioning post, respectively. By setting the second spring, it is convenient to apply a restoring force to the pull plate.

[0012] Furthermore, a fixing plate is fixedly connected to one end of the pull plate, and the fixing plate is provided to facilitate the limiting and fixing of the pipeline.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the device is installed between pipes to limit and block the fluid inside the pipes. When the device is in use, the user pulls the sliding plate, and the sliding plate moves, which drives the elastic rod to move. When the sliding plate moves, it causes the first spring to deform and generate elastic force. When the sliding plate moves, it causes the limiting rod to move and disengage from the inside of the limiting groove. The elastic rod then engages with the inside of the slot, limiting the sliding plate. Then the handle is unrestrained. By setting the limiting device, the handle is effectively limited, which plays a role in positioning the handle. This reduces the possibility of accidental contact of the handle when the device is installed on the pipe, which may cause the handle to rotate and adjust the device's operating status. This improves the practicality of the device.

[0015] 2. In this utility model, by setting a fixing device, when the user pulls the handle during use, the handle moves, causing the pull plate to move. The pull plate then moves on the surface of the limiting plate and the positioning post. When the pull plate moves, it causes the second spring to deform and generate elastic force. When the pull plate moves, it causes the fixing plate to move, and then the fixing plate moves away from the surface of the main body. When the main body is connected to the pipe, the pull plate is released, and the second spring returns to its original position, causing the fixing plate to position the pipe. By setting a fixing device, the pipe is effectively fixed and limited, which plays a role in stabilizing the connection between the pipe and the main body. This reduces the possibility of shaking when the equipment is connected to the pipe during use, which could make it difficult to quickly connect the pipe to the equipment, thus improving the practicality of the equipment.

Detailed Implementation

[0022] Please see Figures 1-5 This utility model provides a technical solution: a clamp-type turbine butterfly valve, including a main body 1, a connecting plate 2, a housing 3, a handle 4 and a limiting device 5. The connecting plate 2 is fixedly connected to the upper surface of the main body 1, the housing 3 is fixedly connected to the upper surface of the connecting plate 2, and the handle 4 is provided on the side of the housing 3.

[0023] The specific settings and functions of the limiting device 5 and the fixing device 6 will be explained in detail below.

[0024] In this embodiment: the limiting device 5 is provided on the side of the housing 3. The limiting device 5 includes a limiting groove 51 and a sliding plate 52. The limiting groove 51 is opened on the surface of the rotating handle 4. The sliding plate 52 is provided on the surface of the rotating plate. A positioning rod 54 is fixedly connected to the side of the housing 3. A limiting rod 53 is fixedly connected to one end of the sliding plate 52. The limiting rod 53 is engaged with the inner wall of the limiting groove 51. A sliding hole 55 is opened on the surface of the sliding plate 52. The positioning rod 54 is slidably connected to the inner wall of the sliding hole 55.

[0025] Specifically, a slide rod 56 is fixedly connected to the inner wall of the sliding hole 55, and the slide rod 56 is slidably connected to the inner wall of the positioning rod 54.

[0026] In this embodiment, by setting the slide bar 56, the slide plate 52 can be limited to move, which reduces the likelihood of the slide plate 52 shaking when moving during use, making it difficult for the slide plate 52 to move smoothly.

[0027] Specifically, a slot 57 is provided at one end of the positioning rod 54, and a spring rod 59 is fixedly connected to the surface of the slide plate 52. The spring rod 59 is provided to facilitate the limiting of the slide plate 52.

[0028] Specifically, a first spring 58 is sleeved and connected to the surface of the slide rod 56. The two ends of the first spring 58 are fixedly connected to the inside of the slide hole 55 and the surface of the positioning rod 54, respectively. The first spring 58 is provided to facilitate the application of a restoring force to the slide plate 52.

[0029] In this embodiment: a fixing device 6 is provided on the side of the main body 1. The fixing device 6 includes a limiting plate 61 and a pull plate 62. The limiting plate 61 is fixedly connected to the side of the main body 1. The pull plate 62 is slidably connected to the surface of the limiting plate 61. A positioning post 63 is fixedly connected to the side of the main body 1. The positioning post 63 is slidably connected to the inner wall of the pull plate 62. A pull handle 65 is fixedly connected to the surface of the pull plate 62.

[0030] In this embodiment: by setting the limiting plate 61, the pull plate 62 can be limited to move, which reduces the likelihood of the pull plate 62 shaking during use, making it difficult for the fixed plate 66 to move smoothly.

[0031] Specifically, a second spring 64 is sleeved and connected to the surface of the positioning post 63. The two ends of the second spring 64 are fixedly connected to the surface of the pull plate 62 and one end of the positioning post 63, respectively. By setting the second spring 64, it is convenient to apply a restoring elastic force to the pull plate 62.

[0032] Specifically, a fixing plate 66 is fixedly connected to one end of the pull plate 62. The fixing plate 66 is set to facilitate the limiting and fixing of the pipeline.

[0033] Working principle: The device is installed between pipes to limit and block the fluid inside the pipes. When in use, the user pulls the slide plate 52, which moves the spring rod 59. When the slide plate 52 moves, it causes the first spring 58 to deform and generate elastic force. When the slide plate 52 moves, it causes the limiting rod 53 to move and disengage from the limiting groove 51. The spring rod 59 then engages with the inside of the slot 57, limiting the slide plate 52. Then the handle 4 is unrestrained. By setting the limiting device 5, the handle 4 is effectively limited and positioned. This reduces the possibility of accidental activation of the handle 4 when the device is installed on the pipe, which could cause the handle 4 to rotate and adjust the device's operating status. This improves the practicality of the device.

[0034] When the device is in use, the user pulls the handle 65, which moves the pull plate 62. The pull plate 62 then moves on the surface of the limiting plate 61 and the positioning post 63. When the pull plate 62 moves, it causes the second spring 64 to deform and generate elastic force. When the pull plate 62 moves, it causes the fixing plate 66 to move, which then moves away from the surface of the main body 1. When the main body 1 is connected to the pipe, the pull plate 62 is released, and the second spring 64 returns to its original position, causing the fixing plate 66 to position the pipe. By setting the fixing device 6, the pipe is effectively fixed and limited, which plays a role in stabilizing the connection between the pipe and the main body 1. This reduces the possibility of shaking when the device is connected to the pipe, which could make it difficult to quickly connect the pipe to the device, thus improving the practicality of the device.
