The CWG-SD type gas drainage pipeline manual water drain is suitable for the automatic drainage of the main, main and branch pipes of the gas drainage and utilization system. The model of the negative pressure manual water drain is CWG-SD, C refers to the abbreviation of drainage (mining) in the gas drainage (mining); W abbreviation of gas in the gas pipeline; G refers to the watt
The CWG-SD type gas drainage pipeline manual water drain is suitable for the automatic drainage of the main, main and branch pipes of the gas drainage and utilization system.
The model of the negative pressure manual water drain is CWG-SD, C is the abbreviation for gas drainage (mining) in gas drainage; the abbreviation for gas in W gas pipeline; G is the abbreviation for pipeline in gas drainage pipeline; SD
It is the abbreviation of manual, so CWG-SD means negative pressure manual water discharge device for gas drainage (mining) pipeline. Negative pressure manual water discharge device is an indispensable automatic water discharge device for coal mine gas drainage system.
Second, the structure of the negative pressure manual water dispenser This product is mainly composed of pressure-resistant cylinder, water inlet valve, air inlet valve, water outlet valve and other components. 1- Drain valve 2- Pressure-resistant cylinder body 3- Intake valve 4- Water inlet valve III. Installation method of negative pressure manual water drain
1. This product should be installed in the low-lying part of the pipeline.
2. Water inlet pipe installation, using pressure-resistant black cloth hose connected with the water inlet valve (muzzle pipe) of the manual water dispenser.
3. The other end of the pressure-resistant black cloth hose is connected to the welded hose button on the bottom of the gas drainage pipe.
4. Working principle The water inlet pipe of the water dispenser is connected to the gas pipeline, and the negative pressure pipe is opened to ensure that the water in the pipeline can smoothly enter the body of the water dispenser. When the water level rises to the height limit of the cylinder (you can pass Inspection window to watch), the special team of the discharge team opened the water outlet at the bottom of the water dispenser and closed the water inlet of the water dispenser; after the water in the cylinder was completely drained, the water inlet valve was closed and the water inlet valve was opened at the same time Continue collecting water and let it drain intermittently.
