The invention discloses an air reservoir with an automatic water drainage function, and belongs to the technical field of engineering machinery. The air reservoir with the automatic water drainage function comprises an air reservoir which is provided with an electric blow-down valve; the inner end of the electric blow-down valve is connected with a flexible rubber hose, and the free end of the flexible rubber hose is connected with a gravity ball; a pressure switch used for detecting the air pressure in the air storage cylinder is installed on the air reservoir, and a contact switch is installed in the air reservoir. The time-delay relay and the contact switch are connected in series to form a control loop; the time-delay relay, the pressure switch and the electric blow-down valve are connected in series to form an execution loop. The air reservoir can automatically discharge water so that the labor intensity is reduced, and the timeliness of water discharge can also be ensured; the pressure switch for gas circuit protection is additionally arranged to ensure that the gas pressure of the gas storage cylinder is not lower than a preset value and the brake pressure is ensured; by additionally arranging the gravity ball and the flexible rubber hose, water can still be discharged normally when the vehicle inclines or swings.

    本发明公布一种具有自动放水功能的储气缸,属于工程机械技术领域。包括储气缸,储气缸上安装有电动排污阀;所述电动排污阀内端连接有软胶管,软胶管自由端连接有重力球;所述储气缸上安装有用于检测储气缸内部气压的压力开关,储气缸内安装有接触开关;延时继电器和所述接触开关串联构成控制回路;延时继电器和所述压力开关、所述电动排污阀串联构成执行回路。本发明储气缸可以自动放水,降低了劳动强度,也能保证放水的及时性;增加了气路保护的压力开关,确保储气缸气压不低于预设值,保证制动压力;通过增加重力球和软胶管,在车辆倾斜或摆动时,依然可以正常放水。
