Air spring release pipeline of marine low-speed machine exhaust valve

An air spring release pipeline of an exhaust valve of a marine low-speed machine comprises a release tank and a pressure relief valve, the upstream of the release tank is connected with the exhaust valve, the upstream of the pressure relief valve is connected with the downstream of the release tank, and the air spring release pipeline is characterized by further comprising a three-way valve, an inlet of the three-way valve is connected with the release tank, and an outlet of the three-way valve is connected with the pressure relief valve. And one outlet is connected with the downstream of the pressure relief valve. According to the utility model, the switch of the three-way valve is rotated, and the oil accumulation condition in the air spring discharge pipeline is observed from the other outlet of the three-way valve, so that a maintainer can conveniently observe the current oil storage quantity in the discharge pipeline, meanwhile, the structure of the discharge pipeline is simplified, and the discharge pat
