The Negative Pressure Automatic Water Discharger is an indispensable automatic water discharge device in coal mine gas extraction systems. It is suitable for automatic water discharge in the main pipes, trunk pipes, and branch pipes of gas extraction and utilization systems.

Structure and Parameters of the Negative Pressure Automatic Water Discharger

The Negative Pressure Automatic Water Discharger mainly consists of the atmospheric valve 1, negative pressure balance pipe 2, tray 3, side guide rod 4, magnet 5, center guide rod 6, outer cylinder 7, water discharge valve protective cover 8, water discharge valve 9, guide seat 10, float 11, water inlet valve 12, and other components.

Applicable Negative Pressure Range: 0 to -0.09 MPa

Automatic Water Discharge Speed: 7 L/min (intermittent discharge)

Dimensions: 415*330*440 mm

Weight: Approximately 31 kg

The speed of the Negative Pressure Automatic Water Discharger for extraction (discharge) pipelines is related to the amount of accumulated water in the pipeline. As usage scenarios vary, it can also be custom-produced according to user requirements. Your choice is welcome.

Precautions for Using the Automatic Water Discharger

1. Collisions during transportation are strictly prohibited; handle with care.

2. After installation, the water discharge valve must not be submerged by water in the roadway; otherwise, it will not be able to discharge water.

3. Keep the area around the water discharger clean to prevent rock (coal) powder (mud) from blocking the water discharge valve.

4. The central axis of the water discharger should be as perpendicular to the horizontal plane as possible to reduce friction resistance during the float's ascent.

5. Regularly check the working condition of the water discharger and address any issues promptly.900
