Zusammenfassung:	The utility model discloses a screw rod sleeve for a hydraulic valve. A sleeve body is a cylinder; a vertical through hole is arranged in the middle of the sleeve body; a stepped outer edge is arranged at the lower end of the sleeve body; fine raised grains are arranged on an outer wall of the stepped outer edge; an annular slot is arranged on the outer wall at the upper end of the sleeve body; and rough grains are polished on the outer wall of the stepped outer edge. According to the screw rod sleeve for the hydraulic valve, due to the structure that the stepped outer edge and the annular slot are arranged outside the sleeve body and the rough grains are polished on the outer wall of the stepped outer edge, the sleeve body can be tightly combined with a screw rod and the clamping firmness is also kept after long-time use.
