Abstract

The invention discloses a multifunctional hydraulic combination valve which comprises a valve seat. An oil leakage screw is installed on the right side of a valve sleeve in a threaded connection mode. The valve sleeve is installed on the right side of the valve seat in a threaded connection mode. A steel ball mounting hole is formed in the left side inside the valve sleeve. A valve seat stepped shaft hole is formed in the right side inside the valve seat. A steel ball seat is installed in the valve seat stepped shaft hole and aligned at the steel ball mounting hole. A steel ball is installed in the steel ball mounting hole and can move in the steel ball mounting hole and the steel ball seat. A mandrel is installed in the middle portion inside the valve sleeve, and an ejector rod of the mandrel corresponds to the steel ball. A spring is installed in the connecting position of the valve sleeve and the oil leakage screw. The front end of the spring abuts against the mandrel, and the rear end of the spring abuts against the oil leakage screw. The multifunctional hydraulic combination valve is simple in structure, convenient to manufacture and machine, and high in response frequency.

Description

technical field [0001] The invention relates to the technical field of hydraulic valves, in particular to a multifunctional hydraulic combined valve. Background technique [0002] The existing unloading overflow valve is composed of an overflow valve and a check valve. When the system pressure reaches the opening pressure of the relief valve, the relief valve opens for unloading; when the system pressure drops to the closing pressure of the relief valve, the relief valve closes and the system continues to load. The unloading relief valve unloads the oil in the system when the pressure reaches a certain value. At present, there is no valve that can prevent air from entering the system when the system oil pressure is lower than the atmospheric pressure, prevent oil leakage before the system oil pressure exceeds the atmospheric pressure, and cut off the oil when the set pressure is reached. . [0003] The hydraulic oil in the hydraulic system is used as the transmission medi...
