Description

Technical Field

[0001] This utility model belongs to the field of butterfly valve technology, specifically relating to a butterfly valve with self-cleaning function. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve. Butterfly valves primarily function to shut off or throttle flow in pipelines. The valve's opening and closing element is a disc-shaped plate that rotates around its own axis within the valve body, thereby achieving the purpose of opening, closing, or regulation.

[0003] A prior art patent, CN217108246U, describes a butterfly valve with a self-cleaning function, comprising a valve body, a butterfly plate, a valve stem, a valve seat, and a rotating handle. The valve stem is fixedly connected to the butterfly plate and rotatably connected to the valve body and valve seat. The top end of the valve stem is fixedly connected to the rotating handle. The butterfly plate is rotatably connected to the inner wall of the valve cavity of the valve body. The butterfly plate includes a first baffle, a second baffle, and an intermediate plate connected between the first and second baffles. A sealing ring is connected to the outer periphery of the intermediate plate, and the sealing ring is in close contact with the inner wall of the valve body. Elastic cleaning pads are connected to the outer periphery of the first and second baffles. Cleaning components are provided on both sides of the butterfly plate. However, in actual use, the following shortcomings still exist: From a practical point of view, in the use of existing butterfly valves, the connection plate and the second baffle are fixed by multiple connecting bolts, which makes the installation or disassembly of the connection plate time-consuming and labor-intensive, increasing labor intensity.

[0004] Therefore, a butterfly valve with a self-cleaning function is needed to solve the problem in the existing butterfly valve where the connecting plate and the baffle are fixed by multiple connecting bolts, which makes the installation or disassembly of the connecting plate time-consuming and labor-intensive, increasing labor intensity.

[0011] In a preferred embodiment, a sealing ring is fixedly installed on the side end of the valve plate, and the sealing ring contacts the inner wall of the valve seat.

[0012] In a preferred embodiment, the number of arc-shaped blocks is several, and the several arc-shaped blocks are arranged in a circular array.

[0013] In a preferred embodiment, the side end of the movable block is provided with anti-slip texture.

[0014] Compared with the prior art, the butterfly valve with self-cleaning function provided by this utility model has at least the following beneficial effects:

To better understand this invention, a detailed description is provided below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1: Basic Structure of a Butterfly Valve

[0027] like Figures 1 to 3As shown, this utility model provides a butterfly valve with a self-cleaning function. It includes a valve seat 1, with a valve plate 2 rotatably mounted inside the valve seat 1. Two grooves 3 are formed on both sides of the valve plate 2. A spring 4 is fixedly installed on the inner wall of each groove 3. A movable block 5 is fixedly installed at one end of each spring 4. Anti-slip textures are formed on the side of the movable block 5. A plug 6 is fixedly installed at one end of the movable block 5. Two mounting grooves 7 are formed on both sides of the valve plate 2. Mounting plates 8 are provided on both sides of the valve plate 2. An arc-shaped block 9 is fixedly installed on the side of each mounting plate 8. A brush 10 is fixedly installed on the side of each arc-shaped block 9, and the brush 10 contacts the inner wall of the valve seat 1. A mounting block 11 is fixedly installed on one side of each mounting plate 8, and the mounting block 11 is movably inserted into the mounting groove 7. A slot is formed on one side of each mounting block 11. 12. The insert 6 passes through one side of the groove 3 and is movably inserted into the slot 12. There are several arc-shaped blocks 9 arranged in a circular array. When installing the arc-shaped blocks 9, the operator pushes the moving block 5 to retract the spring 4, and then inserts the mounting block 11 into the mounting groove 7, releases the moving block 5, and extends the spring 4, so that the insert 6 passes through the groove 3 and is inserted into the slot 12 to limit and fix the mounting block 11, so that the mounting plate 8 is installed on the side of the valve plate 2. When the butterfly valve is opened or closed, the valve plate 2 rotates, which drives the multiple arc-shaped blocks 9 to rotate, so that the brushes 10 on the outer surface of the multiple arc-shaped blocks 9 repeatedly clean the inner wall of the valve seat 1, thereby improving the cleaning effect.

[0028] The outer surface of spring 4 is coated with anti-corrosion paint, which is made of epoxy resin. The anti-corrosion paint improves the service life of spring 4.

[0029] Example 2: Design of the connecting plate

[0030] Several connecting plates 13 are fixedly installed on the side of the valve seat 1. The side of the connecting plate 13 is provided with mounting holes 14. The connection plates 13 and mounting holes 14 facilitate the connection between the valve body and the pipeline.

[0031] Example 3: The function of protrusions

[0032] A valve stem is fixedly installed on the top of the valve plate 2, and a handwheel 15 is fixedly installed on the top of the valve stem. Several protrusions 16 are fixedly installed on the side of the handwheel 15. The protrusions 16 serve to prevent slippage and facilitate the rotation of the handwheel 15.

[0033] Example 4: Design and Function of Sealing Rings

[0034] A sealing ring is fixedly installed on the side end of the valve plate 2. The sealing ring contacts the inner wall of the valve seat 1. The sealing ring enhances the sealing performance between the valve plate 2 and the valve seat 1.

[0035] Example 5: Working principle of a butterfly valve

[0036] When installing the arc-shaped block 9, the operator pushes the moving block 5 to retract the spring 4, then inserts the mounting block 11 into the mounting groove 7, releases the moving block 5, and the spring 4 extends, allowing the insert block 6 to pass through the groove 3 and insert into the slot 12 to limit and fix the mounting block 11, so that the mounting plate 8 is installed on the side of the valve plate 2. When the butterfly valve is opened or closed, the valve plate 2 rotates, driving multiple arc-shaped blocks 9 to rotate, so that the brushes 10 on the outer surface of multiple arc-shaped blocks 9 repeatedly clean the inner wall of the valve seat 1, improving the cleaning effect.

[0037] Technical effect

[0038] Through the detailed description of the above embodiments, firstly, the arrangement of structures such as groove 3, spring 4, moving block 5, insert block 6, mounting groove 7, mounting plate 8, arc block 9, brush 10, mounting block 11 and slot 12 facilitates the installation and disassembly of arc block 9, makes it easy to replace, reduces the labor intensity of workers, and enhances practicality.

[0039] Secondly, the connection plate 13 and the mounting hole 14 facilitate the connection between the valve body and the pipeline. The protrusions 16 provide anti-slip properties and facilitate the rotation of the handwheel 15. The sealing ring enhances the sealing performance between the valve plate 2 and the valve seat 1.

[0040] In summary, this utility model provides a butterfly valve with a reasonable structure, complete functions, and strong applicability, which has a self-cleaning function, can be quickly disassembled and assembled, reduces the labor intensity of workers, and has broad application prospects.
