Detailed description

PCZ-L1 negative pressure automatic water discharge device is an indispensable automatic water discharge device for coal mine gas drainage system. It is suitable for the automatic drainage of the main pipe, main pipe and branch pipe of the gas drainage and utilization system.

Installation of automatic water drain
1. The automatic water drain is installed in the low-lying part of the pipeline.
2. PCZ-L1 negative pressure automatic water dispenser chooses a pipe connection to the main circuit, the other pipe connection to the extraction branch pipe
3. Install a valve at each of the above short sections so that it can be disconnected from the drainage pipe during maintenance of the water drain.
4. The connecting pipe can be a cloth-clamping hose or a steel pipe (using a hose for installation and maintenance).
5. The water inlet control water inlet is located inside the water outlet, the water outlet is an external check valve, and the valve body is a copper check valve.
6. The water inlet of the drain must be lower than the bottom of the pipeline.
7. The centerline of the water drain should be as straight as possible, and the deviation from the horizontal and vertical should be ± 10 °.

Precautions for use
1. Collision is strictly forbidden during transportation. Handle with care.
2. After the water drain is installed, the water drain valve is not allowed to be submerged by the water in the roadway, otherwise the water will not be drained.
3. Clean around the water drain to prevent the rock (coal) powder (mud) from plugging the water drain valve.
4. The central axis of the water dispenser should be as perpendicular to the horizontal plane as possible in order to reduce the frictional resistance during the floating rise.
5. Regularly check the working condition of the water dispenser, and deal with problems when found.
