A seal ring groove is processed on the stationary blade, a seal ring is installed in the seal ring groove, and the seal ring is tightly clamped at two ends through an upper cylinder cover and a lower cylinder cover. Therefore, the rotary vane type hydraulic steering engine cylinder body is divided into a high-pressure area and a low-pressure area through the movable vanes, the static vanes and the sealing rings. However, the three sealing rings of the movable vane are formed by splicing, and vulcanization treatment cannot be carried out on site, so that leakage points can be formed at the spliced positions, leakage occurs in the rotary vane type hydraulic steering engine, namely leakage is formed between a high-pressure area and a low-pressure area, and the sensitivity and the stability of steering are affected.
