水锤吸纳器设置有足够大的气压腔，如 DN100，预压缓冲气压腔很小容积6959cm3。由于气体的可压缩性强，能很好地吸收和释放能量。入水锤吸纳器时，水击波作用于活塞上，活塞将往容气腔方向运动，活塞在一定压力的气体和不规则
水击波双重作用下做上下运动，形成一个动态的平衡，这样就地消除了不规则的水击波震荡。应用行业应用：化工、石化、石油、造纸、采矿、电力、液化气、食品、制药、给排水、市政、机械设备配套、电子工业，城建等领域。适用介质适用介质：水、蒸汽、空气等介质。附件水力控制阀前要安装过滤器，并应便于排污的要求。本类阀门在管道中一般应当水平安装。分类按缓冲气压腔分为：活塞式、胶胆式。

The water hammer absorber is equipped with a sufficiently large air pressure chamber, such as DN100. The preloading buffer air pressure chamber is very small, with a volume of 6959cm3. Due to the strong compressibility of gas, it can absorb and release energy well. When entering the water hammer absorber, the water hammer wave acts on the piston, and the piston will move towards the gas chamber. The piston moves up and down under the dual action of gas with a certain pressure and irregular water hammer wave to form a dynamic balance, so as to eliminate the irregular water hammer wave oscillation on site. Application Industry: chemical industry, petrochemical industry, petroleum, papermaking, mining, electric power, liquefied gas, food, pharmacy, water supply and drainage, municipal administration, mechanical equipment supporting, electronic industry, urban construction and other fields. Applicable media: water, steam, air and other media. A filter shall be installed in front of the accessory hydraulic control 
valve and shall be convenient for blowdown. This type of valve shall be installed horizontally in the pipeline. The classification is divided into piston type and rubber bladder type according to the buffer air pressure chamber.
