Abstract

The present application provides a hydraulic control valve group and a hydraulic valve control cylinder system. The hydraulic control valve group includes: a hydraulic oil conduction module, which is connected with the oil tank and used to conduct hydraulic oil; a hydraulic lock module, which is respectively connected with the hydraulic oil conduction module and the hydraulic oil cylinder, and is used for conducting the hydraulic oil in the hydraulic oil. The hydraulic cylinder is locked under different conduction conditions of the module; the oil return module is connected to the hydraulic lock module and the oil tank respectively, and is used to return the oil to the hydraulic cylinder when the oil tank does not supply oil or the oil supply is insufficient . The hydraulic control valve group improves the oil return effect of the hydraulic cylinder.

Description

technical field [0001] The present application relates to the technical field of automatic control, and in particular, to a hydraulic control valve group and a hydraulic valve control cylinder system. Background technique [0002] A general hydraulic control valve group includes a hydraulic lock module, which can lock the hydraulic cylinder through the hydraulic lock module when different oil circuits are turned on. However, when the hydraulic cylinder falls back under load, it also needs to supply oil to its non-load chamber. Using a general hydraulic control valve group, when the system does not supply oil, the hydraulic cylinder cannot fall back under the load; when the oil supply flow is small, the hydraulic cylinder falls back very slowly. [0003] Therefore, under the control of the existing hydraulic control valve group, the oil return effect of the hydraulic cylinder is poor. SUMMARY OF THE INVENTION [0004] The purpose of the embodiments of the present applicat...
