Summary:The utility model relates to a novel sand control valve, which is composed of a locking nut 1, a regulating screw 2, a connecting base 3, a valve body 4, a valve plate 5, a post rod 6, a connecting plate 7, an electric magnetic head 8, a rolling wheel 9, a sand guiding pipe 10, a spring 11, an impedance screw A12, a valve cap 13, a connecting pipe 14, the impedance screw B15, etc. The rectilinear motion of the valve stem of the electric magnetic head is used to push the valve plate 5 to rotate and make the opening and closing of the sand control valve realized. The sand flow is controlled by the impedance screw A12 and the impedance screw B15, and the vacuum degree of the valve body is regulated by the regulating screw 2 and the locking nut 1. The utility model has the advantages of reasonable structure, convenient operation, reliable performance, long service life, etc., and is used for cutting off machines of superhigh pressure water.
