The invention discloses a high-sealing wear-resistant marine gate valve which comprises a gate valve body, a first valve plate, a second valve plate, a first valve plate control rod, a second valve plate control rod, a control mechanism and a gate valve upper sealing cover. The gate valve body is internally provided with two valve plate sliding grooves capable of being matched with the first valveplate and the second valve plate, the first valve plate and the second valve plate are arranged in the two valve plate sliding grooves correspondingly, the upper end of the first valve plate is provided with a first valve plate control rod, the first valve plate control rod is rotationally connected with the upper end of the first valve plate, the upper end of the second valve plate is provided with a second valve plate control rod, and the second valve plate control rod is rotationally connected with the second valve plate. The gate valve is provided with the two valve plates, synchronous operation of the two valve plates can be realized through the control mechanism, the sealing performance of the gate valve can be improved, the pressure resistance of the gate valve is improved, and reliability and safety of the gate valve are improved.
Description
【Technical field】 [0001] The invention relates to the technical field of valves, in particular to the technical field of marine gate valves. 【Background technique】 [0002] The gate valve is a gate of the opening and closing part. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate plate. Usually, the sealing surface will be surfacing with metal materials to increase wear resistance, such as surfacing welding 1Cr13, STL6, stainless steel, etc. There are rigid gate valves and elastic gate valves. According to the different gate valves, gate valves are divided into rigid gate valves and elastic gate valves. The existing gate valve has a single valve plate structure, and the sealing performance is relatively general. Once the valve plate is damaged, the sealing will be affect...
