Anti-surge valve breather pipe structure

The embodiment of the invention discloses an anti-surge valve breather pipe structure. According to the method, a crankcase ventilation air outlet pipe, an anti-surge valve ventilation pipe, an anti-surge valve and a supercharger are included; an anti-surge valve breather pipe is provided with an outer-layer pipe, a first inner-layer reducer pipe and a second inner-layer reducer pipe, the first inner-layer reducer pipe is used for enabling gas to flow from the large end to the small end, and the second inner-layer reducer pipe is used for enabling the gas to flow from the small end to the large end; the anti-surge valve breather pipe is connected with the anti-surge valve, the crankcase ventilation air outlet pipe and the supercharger. gas exhausted by the crankcase ventilation air outlet pipe and gas exhausted by the anti-surge valve pass through the first inner-layer reducer pipe and the second inner-layer reducer pipe in the anti-surge valve breather pipe, so that the gas flow rate is increased, and the ga
