Air spring pipeline of marine low-speed diesel engine

An air spring pipeline of a marine low-speed diesel engine is connected with a decompression station of a main engine and comprises a discharge tank, the upstream of the discharge tank is connected with an exhaust valve of an air cylinder, the downstream of the discharge tank is connected into a rack through a pressure relief valve, and the air spring pipeline of the marine low-speed diesel engine is characterized in that the discharge tank has an observable function and comprises a body and an observation window, and the observation window is a transparent body. The observation window is connected to the front face of the body in a sealed mode, the condition of the hydraulic oil level in the body can be clearly observed through the observation window, and a ball valve is connected between the discharge tank and the exhaust valve. According to the utility model, the discharge tank with an observable function is adopted, a maintainer can conveniently observe the current oil storage amount in the discharge tank
