水錘吸納器設置有足夠大的氣壓腔，如 DN100，預壓緩沖氣壓腔很小容積6959cm3。由于氣體的可壓縮性強，能很好地吸收和釋放能量。入水錘吸納器時，水擊波作用于活塞上，活塞將往容氣腔方向運動，活塞在一定壓力的氣體和不規(guī)則
水擊波雙重作用下做上下運動，形成一個動態(tài)的平衡，這樣就地消除了不規(guī)則的水擊波震蕩。應用行業(yè)應用：化工、石化、石油、造紙、采礦、電力、液化氣、食品、制藥、給排水、市政、機械設備配套、電子工業(yè)，城建等領域。適用介質適用介質：水、蒸汽、空氣等介質。附件水力控制閥前要安裝過濾器，并應便于排污的要求。本類閥門在管道中一般應當水平安裝。分類按緩沖氣壓腔分為：活塞式、膠膽式。

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.
