Air volume composite adjusting device based on reciprocating piston type air compressor and air compression system

The utility model discloses an air volume composite adjusting device based on a reciprocating piston type air compressor and an air compression system, and belongs to the field of compressors. The two sides of a compression air cylinder of the reciprocating piston type air compressor are connected with two air inlet valves arranged in a spaced mode and two air outlet valves arranged in a spaced mode respectively, and the air inlet valves and the air outlet valves are one-way valves. The two air inlet valves are respectively connected with an unloading control valve, and the unloading control valves are normally closed pneumatic control valves; and the two unloading control valves are respectively connected with an electromagnetic directional valve. The device is simple in structure, convenient to implement, reliable in control according to tests, good in use effect and high in application value. The utility model further discloses an air compression system. 本实用新型公开了一种基于往复活塞式空气压缩机的气量复合调节装置及空气压缩系统，属于压缩机领域。往复活塞式
