Electric control automatic exhaust valve

The invention discloses an electric control automatic exhaust valve which comprises a gas collecting pipe, an exhaust pipe and a gas inlet pipe are arranged at the two ends of the gas collecting pipe respectively, an electromagnetic valve is installed on the exhaust pipe, a first inductive switch and a second inductive switch are arranged in the gas collecting pipe, and the electromagnetic valve is electrically connected with an electric control device for controlling on-off of the electromagnetic valve. The electric control device is electrically connected with the first inductive switch and the second inductive switch; the liquid level height of the gas collecting pipe is monitored through the inductive switch, opening and closing of the electromagnetic valve are controlled through the relay, and the purpose of automatic exhaust is achieved; automatic control is achieved, air in a pipeline can be exhausted in time, the labor intensity of workers and operation errors of the workers are reduced, and no refrig
