For hydraulic valves using manual control, the control component module is generally adjusted by using a handle and a control screw in conjunction to achieve control of the liquid flow and blocking. Generally, the blocking head blocks the pipe mouth of the liquid inlet. Under long-term working conditions, the liquid entering it causes scouring and erosion to the blocking head. When sealing work is required, a gap will be generated when the blocking head contacts the pipe mouth of the liquid inlet pipe, thereby affecting its sealing control work.

[0004] To this end, the present invention proposes a control module for a hydraulic valve to solve the above-mentioned problem. Summary of the invention

The other end is in the placement groove of the connector 2, and the bottom end of the regulating screw 21 also extends into the placement groove. By rotating the regulating screw 21, the bottom end of the regulating screw 21 squeezes the transmission inclined groove 305 on the side of the regulating shaft 303, thereby driving the spherical plugging head 304 at the other end of the regulating shaft 303 to plug the port of the liquid inlet 11; the accommodating cavity 301 in the regulating component is arranged in the hydraulic valve body 1, and the regulating shaft 303 is adapted and plugged in the accommodating cavity 301, and the regulating shaft 303 A spherical plugging head 304 is provided at one end, and the spherical plugging head 304 extends into the spherical cavity 13.
