Description

Adjustable water hammer eliminator Technical Field The utility model relates to the technical field of pipeline engineering, in particular to an adjustable water hammer eliminator. Background In fluid conveying systems such as petrochemical industry, water supply and drainage, heat supply and heating, and the like, water hammer phenomenon (pressure shock wave caused by sudden change of fluid flow velocity due to rapid opening and closing of a valve, starting and stopping of a pump set, and the like) can cause severe impact on pipelines and equipment, and cause safety problems such as vibration, sealing failure, pipe explosion, and the like. The water hammer eliminator is used as a core protection device and needs to effectively absorb the pressure wave energy. However, the water hammer eliminator is used as a core protection device, the buffering pretightening force cannot be changed along with the impact strength, the violent water hammer of the high-pressure high-flow pipeline is possibly insufficiently buffered, the low-pressure low-flow pipeline is possibly excessively buffered to influence normal conveying, and the current limiting plate is easily deflected due to the defect of a guiding structure under high-pressure impact, so that the sealing surface is worn and the regulation is malfunctioning. Therefore, an adjustable water hammer eliminator is proposed to address the above problems.
