The invention relates to an automatic exhaust valve which is mainly suitable for a fluid conveying system. The exhaust valve mainly comprises a valve body, a valve cover, a rubber pad, a valve bonnet, an exhaust nozzle, a sealing pad, a guide sleeve, a sealing ring, a guide rod, a sealing rubber pad, a floating ball and the like. The valve cover is in threaded connection with the valve body, the exhaust nozzle and the guide sleeve are arranged in a through hole of the valve cover, and the sealing rubber gasket is arranged at the top end of the guide rod and moves up and down in the guide sleeve along with the guide rod. The floating ball is fastened on the guide rod, and when liquid in the valve body rises, the floating ball floats due to the action of buoyancy, so that the guide rod is driven to move upwards until the through hole in the lower end of the exhaust nozzle is sealed by the sealing rubber mat, and the exhaust valve is closed. At the moment, after gas in the liquid enters the valve body, the liqui
