[Case Study] Fundamental Measures Against Water Hammer
Adopting a special butterfly valve as a fundamental measure against water hammer!
At a steel manufacturing company, a cylinder valve was installed for flow adjustment in the factory's piping system. However, it has been reported that fine-tuning the valve opening is difficult, leading to the occurrence of water hammer, which damages the piping. They consulted us to see if there is a valve that can reduce the hammer. Issues: 1. The current cylinder valve makes it difficult to finely adjust the valve opening. (It goes from fully open to fully closed suddenly.) 2. They want to reduce water hammer and extend the lifespan of the piping. *Water hammer refers to a phenomenon, also known as water shock, that occurs when the flow of water in a pressurized pipe is suddenly stopped, causing a shock and high pressure to develop within the pipe due to the inertia of the water. When the water or steam in the piping is instantaneously halted, the kinetic energy of the fluid has nowhere to go and is converted into pressure energy, resulting in a rapid increase in pressure within the piping (pressure fluctuation) and the generation of a "high-pressure wave" (shock wave). This pressure wave can propagate instantaneously over long distances through the piping and fluid (in water, at speeds exceeding 1,400 meters per second), causing unusual noises (such as knocking sounds) in locations far from the source of the problem and potentially damaging the piping or valve body.
