The invention relates to the technical field of valves, in particular to an anti-leakage high-sealing valve. The valve has the beneficial effects that a dual-protection function can be achieved on the valve, and the leakage risk is reduced. An anti-leakage high-sealing valve comprises an outer valve body, an inner valve body is embedded in the outer valve body, hoses are connected to the two ends of the inner valve body in a communicating mode, flange bases are connected to the outer ends of the two hoses in a communicating mode, the two flange bases are rotationally connected to the two ends of the outer valve body respectively, and when the two flange bases rotate, the two hoses can be driven to rotate; a plurality of rubber flow deflectors are arranged on the inner walls of the two hoses in a surrounding manner; a valve element is rotationally connected into the inner valve body, a through flow channel I is formed in the valve element, a valve rod I is fixedly connected to the valve ...

The invention relates to the field of valves, in particular to an oil field oil extraction water injection valve. The valve has the beneficial effects that the angle displacement deviation generated in the valve body mounting process can be compensated, the strong pressure difference generated at the moment of opening and closing of the valve body is reduced, and the situation that the inner wall of the valve body is damaged due to the fact that the strong pressure difference generates strong impact on the inner wall of a valve body pipeline is avoided. A water injection valve for oil extraction in an oil field comprises a valve body, a valve element is rotationally connected into the valve body in a sealed mode, a valve rod is fixedly connected to the valve element, the valve rod is rotationally connected to the valve body in a sealed mode, rotating seats are connected to the two ends of the valve body in a sealed and communicated mode, rubber corrugated hoses are rotationally connected ...
