一种水表冲洗系统
By designing a water meter flushing system, the system utilizes the drainage pressure of a pneumatic diaphragm pump or static water source, combined with butterfly valves and shut-off valves, to achieve automatic or semi-automatic flushing of water meters. This solves the problem of water meter jamming and improves the reliability and service life of the equipment.

AI Technical Summary
Water meters at the fully mechanized mining face are prone to jamming, resulting in labor-intensive, time-consuming, and material-wasting repairs, a problem that is difficult to solve effectively with existing technologies.
Design a water meter flushing system that utilizes the drainage pressure of a pneumatic diaphragm pump or a static water source, and through a combination of butterfly valves and shut-off valves, to achieve automatic or semi-automatic flushing of the water meter and remove internal impurities.
This effectively avoids water meter jamming, reduces maintenance workload and material waste, and improves the operational reliability and service life of water meters.

Abstract
Claims
1. A water meter flushing system characterized by: The system includes a water meter (1) and a drainage pipe (2). The water meter (1) is installed above the drainage pipe (2). The drainage pipe (2) is connected to a diaphragm pump. The system also includes a second butterfly valve (4) and a first butterfly valve (3). The second butterfly valve (4) and the first butterfly valve (3) are installed on the drainage pipe (2). The water meter (1) is connected above the drainage pipe (2) between the second butterfly valve (4) and the first butterfly valve (3). The second butterfly valve (4) is located at the water inlet of the water meter (1). On the side, the butterfly valve one (3) is set on the water outlet side of the water meter (1), and a drain valve (5) is connected below the drain pipe (2) between the butterfly valve two (4) and the butterfly valve one (3). The drain valve (5) is set on the water inlet side of the water meter (1). The drain pipe (2) between the water outlet side of the water meter (1) and the water inlet side of the butterfly valve one (3) is connected to a stop valve one (6). The stop valve one (6) is connected to a high-pressure hose (8). The high-pressure hose (8) is connected to a flushing water source.
2. A water meter flushing system according to claim 1, characterised in that: The drainage pipe (2) is fixedly connected to the drain valve (5) through a straight-through two-way valve and is perpendicular to the drainage pipe (2).
3. A water meter flushing system according to claim 1, wherein: The drainage pipe (2) is connected to the stop valve (6) via a straight-through valve.
4. A water meter flushing system according to claim 3, wherein: The straight section is fixedly connected to the drainage pipe (2) at a 45° angle.
5. A water meter flushing system according to any one of claims 1 to 4, wherein: The drain pipe (2) on the inlet side of the butterfly valve (4) is connected to the stop valve (7), and the stop valve (7) is connected to the stop valve (6) through the high-pressure hose (8).
6. A water meter flushing system according to any one of claims 1 to 4, wherein: The high-pressure hose (8) is connected to an external static water supply.
