Introduction to standard models of positive and negative pressure automatic water drainers

The model of the negative pressure automatic water drainer is CWG-FY, C refers to the abbreviation of gas drainage (mining); W refers to the abbreviation of gas in gas pipes; G refers to the abbreviation of pipeline in gas drainage pipes; FY is the abbreviation of negative pressure, so CWG-FY means the negative pressure automatic water drainer used in gas drainage (production) pipelines.

Standard usage precautions for positive and negative pressure automatic water drainers

1. Collision is strictly prohibited during transportation and must be handled with care.

2. After the water discharger is installed, the water discharge valve is not allowed to be submerged by the water in the tunnel, otherwise it will not be able to discharge water.

3. Keep the area around the drain valve clean to prevent rock (coal) powder (mud) from burying the drain valve.

4. The central axis of the water discharger should be as perpendicular to the horizontal plane as possible to reduce the frictional resistance during the rise of the float.
