 I. Overview 
 YQ-9000 to absorb water hammer piston device is used to eliminate the pipeline for a variety of causes of water hammer shock wave to protect pipelines and equipment from damage to the device. For industrial and mining enterprises, high-rise buildings, power plants and other water supply and drainage system, the use of the piston air chamber expansion and contraction, so that sudden shock wave intensity by buffering and mitigation of the maximum level to avoid water hammer due to huge momentum due to equipment damage. The simple structure, excellent selection, long service life.
