The utility model discloses a device eliminating influence on a pipeline from a cutoff close water hammer in the water delivery pipeline. The device comprises an air absorbing and exhausting valve arranged on the hump position of a main water delivery pipe. The air absorbing and exhausting valve is connected with the hump portion of the main water delivery pipe through a connecting pipe. As the combined type air absorbing and exhausting valve absorbing air fast and exhausting the air slowly is arranged on the hump portion of the main water delivery pipe, the cutoff close water hammer phenomenon in the main water delivery pipe is effectively avoided. As the pressure fluctuation in a whole water delivery system is lowered greatly, the safety reliability of the main water delivery pipe, other equipment and a pump station in the water delivery system is effectively improved. The device is simple in structure, low in manufacturing cost and reliable in operation, and has great significance to the safety of the wate
