Problems solved by technology

With the 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 slowly
[0003] Therefore, under the control of the existing hydraulic control valve group, the oil return effect of the hydraulic cylinder is poor

Abstract

The invention provides a hydraulic control valve group and a hydraulic valve control cylinder system. The hydraulic control valve group comprises a hydraulic oil conduction module connected with an oil tank and used for conducting hydraulic oil, a hydraulic locking module connected with the hydraulic oil conduction module and the hydraulic oil cylinder and used for locking the hydraulic oil cylinder under different conduction conditions of the hydraulic oil conduction module, and an oil returning module connected with the hydraulic locking module and the oil tank and used for enabling the hydraulic oil cylinder to return oil when the oil tank does not supply oil or the oil supply amount is insufficient. The hydraulic control valve group improves the oil returning effect of the hydraulic oil cylinder.

Description

technical field [0001] The present application relates to the technical field of automatic control, 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, and the hydraulic cylinder can be locked by the hydraulic lock module under different conduction conditions of the oil circuit. However, when the hydraulic cylinder falls back under load, it also needs to supply oil to its non-load chamber. With the 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 slowly. [0003] Therefore, under the control of the existing hydraulic control valve group, the oil return effect of the hydraulic cylinder is poor. Contents of the invention [0004] The purpose of the embodiment of the present applicati...
