Description

Sewage treatment is with waterproof hammer pressure equaliser

Technical Field

The invention belongs to the field of sewage treatment, and particularly relates to a water hammer-proof pressure balancing device for sewage treatment.

Background

In the process of sewage treatment, a water hammer phenomenon easily occurs to damage pipelines, valves and the like, wherein the water hammer phenomenon refers to that when power is suddenly cut off or the valves are closed too fast, water flow shock waves are generated due to the inertia of pressure water flow, and the water hammer is called as a hammer to beat. The force generated by the water shock wave back and forth is sometimes very large, thus damaging valves and pipes.

When the valve is suddenly closed, the upstream fluid continues to be delivered forward by inertia, causing a large impact at the upstream end of the valve, which is too high and causes the pipe to break, while the downstream fluid continues to be delivered forward, which creates a low pressure space at the downstream end of the valve, which is too low and causes the pipe to collapse.

Therefore, we propose a water hammer-proof pressure balancing device for sewage treatment to solve the above problems.
