Fully automatic negative pressure drain valve, gas pipeline negative pressure drain valve, negative pressure drain valve CWG-FY type
The CWG-FY fully automatic negative pressure drain is a type of drain used in the negative pressure state of coal mine gas drainage pipelines Water dispenser is an indispensable automatic drainage device in coal mine gas drainage system, suitable for automatic drainage of main, main and branch pipes of gas drainage and utilization system. If the water volume in the gas pipeline is large, it will cause a significant reduction in the effective cross-section of the local pipeline, and even block the drainage pipeline, seriously affecting the drainage effect. Therefore, the problem of water blockage is extremely prominent during the on-site drainage process. The key equipment to solve the problem of water blockage is the drain device
