The invention discloses an anti-blocking type control valve for spraying and dust reduction of a hydraulic support. The anti-blocking type control valve comprises a valve body; a water inlet, two water outlets, two control liquid inlets and two valve cavities are formed in the valve body; the water inlet and the water outlets communicate through the valve cavities; valve core assemblies are arranged in the valve cavities and are each of a non-rigid combination structure; an anti-blocking filter device comprising a dust particle decomposition knife is arranged between the water inlet and the valve cavities; the two valve cavities communicate through a communicating hole; the valve core assemblies are provided with two-way control liquid driving structures formed by the two control liquid inlets; the two water outlets can communicate with the water inlet through the valve cavities and horn openings correspondingly, or the two water outlets communicate with the water inlet through the valve cavities and the horn openings simultaneously; and the valve core assemblies block the horn openings through self-reset valve core heads. The anti-blocking type control valve has the beneficial effects that the stroke of valve cores is short, the opening and closing response of a valve opening is fast, and the service life of sealing elements is long; and the valve cores is free of blocking hidden danger, the structure is compact, the compressive ability is high, and the service life is long.
