TECHNICAL FIELD
[0001] The utility model relates to flange technical field especially a kind of anti-blocking flange. BACKGROUND
[0002] In industrial, civil building water supply and other fluid conveying systems, pipelines are usually used to transport various liquid media. For some low-frequency pipeline systems, when they are in idle state for a long time, rust, silt and other impurities may accumulate inside. These impurities will be flushed down with the water flow at the initial stage of pipeline restart, and may enter the equipment or facilities connected downstream of the pipeline, causing equipment wear and tear, efficiency reduction, and even failure or blockage, thereby increasing maintenance costs and potential safety risks.
[0003] Currently, there are some preventive measures on the market to reduce the occurrence of the above problems, such as regular flushing of the pipeline, installation of fixed filters or use of bypass discharge to remove initial sewage. However, these methods either require additional manpower and material resources to maintain frequently, or cannot completely solve the problem of impurities entering the downstream at the initial use, and the fixed filter easily causes a loss of water pressure, affecting normal water supply. In order to solve the problems existing in the prior art, the present application provides a new type of anti-blocking flange device, which can intercept and discharge the initial sewage containing more impurities after the pipeline is not used for a long time, while ensuring that the subsequent clean water flow can also pass quickly.

In this way, the water flow containing a large amount of impurities in the initial stage is blocked, and after being filtered by the filter screen 22, it flows out, and the impurities are deposited below the front side of the filtering assembly 2 and can be discharged through the blowdown opening 12. As the water flow gradually becomes clean, the control handle 31 is rotated again, so that the filtering assembly 2 deviates from the plugging position, and the smoothness of the medium channel 11 is restored, ensuring that the clean water flow can quickly flow to the downstream equipment.
