Description

Technical Field

[0001] This application relates to the field of butterfly valve technology, and in particular to a high-sealing, anti-jamming butterfly valve for gas filling. Background Technology

[0002] Hand-operated butterfly valves are simple in structure and flexible in operation, widely used in pipeline systems to cut off or regulate fluid flow. This valve uses a rotating handle to move the valve stem, causing the butterfly plate to open or close rapidly within a 90° range, thus controlling the flow of fluid. Hand-operated butterfly valves are small in size and lightweight, easy to install and maintain, and particularly suitable for space-constrained applications. They offer good sealing performance and are suitable for media including water, air, oil, and some corrosive fluids.

[0003] Currently, in gas-filled butterfly valves, the connection between the valve handle and the valve body is exposed to the outside environment, which is subject to erosion from rainwater and dust. This can lead to blockage of gaps or difficulty in turning the handle, resulting in jamming. Consequently, the handle cannot effectively drive the butterfly valve to rotate and adjust. Therefore, a high-sealing anti-jamming butterfly valve for gas filling has been designed to solve the aforementioned problems. Utility Model Content

[0004] To address this problem, this application provides a high-sealing, anti-jamming butterfly valve for gas filling.

[0005] The high-sealing, anti-jamming butterfly valve for gas filling provided in this application adopts the following technical solution:

[0006] A high-sealing, anti-jamming butterfly valve for gas filling includes a butterfly valve body. A rotating rod is rotatably connected to one side of the butterfly valve body, and a protective frame is slidably connected to one side of the rotating rod. A rotating handle is fixedly connected to one side of the protective frame. An oil storage tank is provided inside one side of the protective frame. Flow grooves are provided at the upper and lower ends of the protective frame and are connected to the oil storage tank. Fixed grooves are provided at the upper and lower ends of the protective frame and are connected to the flow grooves. A stop block is slidably connected to the fixed groove.

[0007] Preferably, one side of the stop is arc-shaped, and the stop blocks the flow groove.

[0008] Preferably, an elastic sheet is fixedly connected to one side of the stop block, and the elastic sheet is fixedly connected to the inner wall of the fixing groove on one side.

[0009] Preferably, a magnetic plate is fixedly connected to one side of the protective frame, and the magnetic plate and the rotating rod are magnetically connected.

[0010] Preferably, the oil storage tank has an opening at its upper end, and the opening is threadedly connected to a sealing plug.

[0011] Preferably, the rotating rod consists of a rotating column and a rotating column, and the upper and lower ends of the rotating rod are provided with limiting grooves.

[0012] Preferably, a plug plate is fixedly connected to one side of the butterfly valve body, and a slot is provided on one side of the protective frame, into which the plug plate is inserted.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] In this utility model, by using a protective frame to cover the rotating rod, the gap at the connection between the rotating rod and the butterfly valve body can be protected, preventing dust from entering and also preventing the rotating rod from being directly exposed to the outside, which could lead to rust, inability to rotate, or jamming. Furthermore, the flow groove set inside the protective frame allows lubricating oil to flow out when the rotating rod and the protective frame are separated, thereby lubricating the rotating rod and preventing rust.

[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0022] This application discloses a high-sealing, anti-jamming butterfly valve for gas filling. (See also...) Figure 1-5 A high-sealing, anti-jamming butterfly valve for gas filling includes a butterfly valve body 1, a rotating rod 2 rotatably connected to one side of the butterfly valve body 1, a protective frame 3 slidably connected to one side of the rotating rod 2, a handle 4 fixedly connected to one side of the protective frame 3, an oil storage tank 5 inside the protective frame 3, an opening at the upper end of the oil storage tank 5, and a sealing plug threadedly connected to the opening. Flow grooves 6 are provided at the upper and lower ends of the protective frame 3, communicating with the oil storage tank 5. Fixed grooves 7 are provided at the upper and lower ends of the protective frame 3, communicating with the flow grooves 6, and a stop block 9 slidably connected to the fixed groove 7.

[0023] One side of the stop 9 is curved, such as Figure 4 As shown, the block 9 blocks the flow groove 6, and an elastic sheet 8 is fixedly connected to one side of the block 9. The elastic sheet 8 is fixedly connected to the inner wall of the fixing groove 7 on one side.

[0024] By adopting the above technical solution, a magnetic plate 31 is fixedly connected to one side of the inner side of the protective frame 3, and the magnetic plate 31 and the rotating rod 2 are magnetically connected.

[0025] By adopting the above technical solution, the rotating rod 2 is composed of a rotating column and a rotating column, and the upper and lower ends of the rotating rod 2 are provided with limiting grooves 21.

[0026] By adopting the above technical solution, a plug plate 11 is fixedly connected to one side of the butterfly valve body 1, and a slot 10 is provided on one side of the protective frame 3. The plug plate 11 is inserted into the slot 10 to cover the connection between the rotating rod and the butterfly valve body 1, so as to avoid direct exposure. At the same time, the protective frame 3 covers the rotating rod 2, so that the rotating rod 2 is protected.

[0027] The implementation principle of a high-sealing anti-jamming butterfly valve for gas filling in this application embodiment is as follows: First, open the sealing plug, then pour lubricating oil into the oil storage tank 5. In the initial state, the butterfly valve body 1 is in the closed state, and gas cannot pass through. The slot 10 of the protective frame 31 is inserted into the insert plate 11. At this time, the protective frame 3 and the handle 4 are limited by the insert plate 11 and cannot rotate, thus preventing accidental contact. Simultaneously, the protective frame 3 covers the rotating rod 2, protecting it and preventing dust from entering the gap between the rotating rod and the butterfly valve body. When rotation is required... When adjusting the opening and closing of the butterfly valve body 1, first pull the mounting frame 3 to move it away from the butterfly valve body 1 and separate the magnetic plate 31 from the rotating rod 2. During the movement, the stop block 9 will be squeezed and move into the fixed groove 7, squeezing the elastic plate 8 to contract. After the stop block 9 moves, the connection between the flow groove 6 and the fixed groove 7 will not be blocked, allowing the lubricating oil to flow out from one side and contact the rotating rod 2. The rotating rod 2 will be lubricated to prevent rust. Then turn the handle 4 to make the handle 4 drive the protective frame 3 to rotate, and the protective frame 3 will drive the rotating rod 2 to rotate.
