 The invention relates to the technical field of valves, in particular to a kingston valve with a non-return function. The kingston valve comprises an electric device, a lifting device, a valve rod, a valve deck, a sealing assembly, a valve body, a valve flap, a valve flap cover and a spring. The electric device is connected with the lifting device. A lifting channel, an inlet channel and an outlet channel which communicate with one another are arranged in the valve body. A first sealing end is arranged between the inlet channel and the outlet channel. A second sealing end is arranged outside the valve flap. The valve deck is fixedly connected with an end opening of the lifting channel. Installation holes are formed in the valve deck. The sealing assembly is arranged in the installation holes. The valve flap cover is fixedly connected with an opening of the valve body. One end of the valve rod is connected with the lifting device, and the other end of the valve rod penetrates through the sealing assembly and the valve flap cover to be arranged inside the valve flap. The valve rod is in threaded fit with the sealing assembly. The spring is arranged in the valve flap. One end of the spring abuts against the valve rod, and the other end of the spring abuts against the valve flap cover. The kingston valve with the non-return function can prevent seawater intrusion, so that the safety of a naval ship is improved.
