71208120 Series Pressure Pipeline Safety Valve

71208120 Series Pressure Pipeline Safety Valve

1. Water column separation in high places or long water pipelines often occurs due to pressure reduction during power outages or pump shutdowns. To protect the pipelines, an air valve can be installed. The air valve is sometimes called the exhaust valve or intake valve.
2. Install air valves at the high points of the pressure water tank of the pumping station and on each water pipeline to discharge the air in the water pipeline when it is filled with water during the initial filling of the water pipeline and after regular maintenance of the pipeline to avoid pressure. Fluctuation; when water hammer occurs and negative pressure occurs in the water pipeline, the air valve opens, allowing air outside the pipeline to enter the pipeline to avoid generating a large negative pressure in the pipeline, which plays a protective role; when the pipeline system is running, when the pressure inside the pipeline When air dissolved in water is released due to temperature changes, the air valve will discharge it in time to prevent air bags from forming in the pipeline and affecting the operation of the pipeline system.
