Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve for mine drainage. Background Art

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc., and can also be divided into ball valves, butterfly valves, gate valves, etc. according to the type of their opening parts. Butterfly valves are valves with a relatively simple structure. They are opened and closed by rotating the disc-shaped opening and closing parts around the valve shaft. They can be used for pipelines with flowing low-pressure media and are widely used in various places. Butterfly valves are often used in drainage pipes in mining to open and close drainage pipes. Butterfly valves have a simple structure and are easy to install. They are also convenient to use and are very suitable for use in narrow environments such as mines and pits.

[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the existing drainage valve guides and discharges the mine water flow containing a large amount of fine particles, since the water flow contains a large amount of fine particles, it is easy to cause the particles to adhere to the inner wall of the internal channel of the valve. After a period of use, a layer of adhesion will be generated in the internal channel of the valve, thereby causing the cross-sectional area of ​​the internal channel of the valve to be occupied by the adhesion layer, resulting in a decrease in the water flow rate and even blockage. It needs to be disassembled and cleaned frequently, and the convenience of use is poor. Utility Model Content

[0004] The utility model aims to provide a mine drainage valve which does not require disassembly and is simple to clean, in view of the defects and shortcomings of the prior art.

[0006] A further improvement is that a connecting plate is also provided on one side of the valve body.

[0007] A further improvement is that a twist handle is also provided on the top of the opening and closing member.

[0008] A further improvement is that the pulling block comprises a moving block slidably arranged on the outer wall of the valve body and a first magnetic block embedded in a side of the moving block close to the valve body.

[0009] A further improvement is that a rolling wheel is movably engaged on one side of the movable block close to the valve body.

[0010] A further improvement is that a handle is also provided on the outer surface of the movable block.

[0011] A further improvement is that: a guide track is also provided at the outer wall of the valve body where it is connected to the moving block.

[0012] A further improvement is that the cleaning block comprises a moving block slidably arranged on the inner wall of the valve body and a second magnetic block arranged in the moving block, and the outer wall of the moving block is provided with a scraping frame with a top that fits the inner cavity of the valve body.

[0013] A further improvement is that a plurality of through holes are provided in the middle section of the scraper frame.

[0014] A further improvement is that: a sliding groove slidably connected to the scraper frame is provided at the connection position between the moving block and the scraper frame, and a compression spring is provided between the inner wall of the sliding groove and the connection position of the scraper frame.

[0015] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when the inner cavity of the valve body is blocked, the utility model only needs to pull the pulling block, so that the movable cleaning block is driven to move by magnetic force, and the scraping frame of the cleaning block is used to loosen and scrape off the attachment layer attached to the inner wall of the valve body, and then the loose attachment layer is washed away by the flowing water flow, thereby making the cleaning of the valve easier and without the need to stop work and disassemble.

The magnetic block 62 moves together with the movable block 61, and moves straightly under the action of the guide groove 8, thereby causing the scraper frame 63 arranged on the outer wall of the movable block 61 to move along the inner cavity of the valve body 1. During the movement of the scraper frame 63, the attachment layer in the inner cavity of the valve body 1 is stirred and scraped off, thereby loosening or scraping off the attachment layer on the inner wall of the valve body 1, and then when the water flow in the valve body 1 continues to flow, the attachment can be washed away and cleaned by the water flow, thereby making the cleaning of the valve easier and without the need to stop work and disassemble.
