A valve bottom lining cleaning device

Abstract

The invention discloses a valve bottom lining cleaning device. The two ends of a valve are connected with a water inlet pipe and a water outlet pipe; a water stop rubber bottom lining is arranged in the valve; a mounting hole is formed in the top of the water inlet pipe; the cleaning device comprises a connecting rod, a swing rod, a positioning sleeve, a sealing pipe and a sealing valve; the connecting rod extends into the water inlet pipe through the mounting hole, and the lower end is hinged with the swing rod; the positioning sleeve is arranged out of the connecting rod, and penetrates through the mounting hole to extend into the water inlet pipe; an inclined mouth is arranged at the lower end of the positioning sleeve; the sealing pipe is arranged out of the positioning sleeve, and thelower end is fixed in the mounting hole; the sealing valve is arranged out of the sealing pipe; the cleaning device is fixed at the upper end of the water inlet pipe; an iron removing hole is formedin the swing rod; a magnet is bonded on the inner wall of the top end of the swing rod; a brush sleeve sleeves the outer side of the swing rod; and a brush is arranged at the bottom of the brush sleeve, and a rectangular hole is formed in the side surface. The valve bottom lining cleaning device solves the problem of damage of the water stop rubber bottom lining caused by pipe impurity silting inthe valve closing process, reduces the replacement frequency in the valve use process, and reduces the maintenance cost.

Description

technical field [0001] The invention relates to the field of cleaning devices, in particular to a valve bottom lining cleaning device. Background technique [0002] The uneven distribution of water resources has brought great pressure to my country's social and economic development. A series of water transfer projects represented by the South-to-North Water Diversion Project have made outstanding contributions to alleviating the lack of regional water sources. As the main water supply objects in urban areas, pipeline water supply has outstanding advantages. It has the advantages of saving land, facilitating construction and convenient management. Ball valves and other valves are often used to adjust the water supply flow in water transmission lines with large pipe diameters. However, there are the following problems in maintenance: on the one hand, it is more complicated to control the water quality, and the investment is relatively large. As a part of the water transmission ...

Problems solved by technology

Ball valves and other valves are often used to adjust the water supply flow in water transmission lines with large pipe diameters. However, there are the following problems in maintenance: on the one hand, it is more complicated to control the water quality, and the investment is relatively large. As a part of the water transmission system, pipeline water transmission is often Combined with channels, diversion tunnels, aqueducts, etc. to form a complete water diversion system, due to weather, human factors and other factors, it is inevitable that debris will enter the water body. During the operation of pipeline projects, debris and sediment deposits often cause the bottom of the valve to Siltation, when the valve is closed, sundries and sediment are stuck on the bottom of the water-stop rubber bottom, causing plastic deformation of the water-stop rubber bottom and reducing the service life of the valve; on the other hand, the maintenance of large-diameter water transmission lines is complicated , which will have adverse effects on management and operation. Only improving the valve structure and process cannot effectively eliminate the impact of debris deposition on the valve water-stop rubber lining. Therefore, a valve bottom lining cleaning device is needed, which can effectively remove debris. It can also extend the maintenance cycle of the valve
