Abstract

The invention provides a hydraulic reversing valve and a hydraulic reversing device, and relates to the technical field of reversing valves. The hydraulic reversing device comprises a valve body, a valve sleeve and a valve element. The valve body is provided with a first installing cavity and further comprises a pressure oil port, an oil return port, a first work port and a second work port whichcommunicate with the first installing cavity, and the valve sleeve is arranged in the first installing cavity. The valve sleeve is provided with a second installing cavity, the valve sleeve is provided with a plurality of oil grooves in the circumferential direction, and the multiple oil grooves are provided with liquid passing holes communicating with the second installing cavity. The valve element comprises a first liquid passing groove and a second liquid passing groove which are distributed in the axial direction, and the valve element is rotationally arranged in the second installing cavity. The hydraulic reversing valve can meet the usage requirements for the high reversing frequency and high work pressure of execution mechanisms of some devices through combination of the valve body,the valve sleeve and the valve element, cooperation of the liquid passing grooves and the liquid passing holes in the oil grooves and gap seal between the valve element and the valve sleeve. The hydraulic reversing device is formed by the hydraulic reversing valve and a drive mechanism, and the usage requirements can be met as well.

Description

technical field [0001] The present application relates to the technical field of reversing valves, in particular to a hydraulic reversing valve and a hydraulic reversing device. Background technique [0002] In the field of hydraulic engineering, directional valves are widely used. [0003] The reversing frequency of the executive mechanism of some equipment is high, and the existing spool valve reversing valve has a relatively low reversing frequency due to inertia, which cannot meet the high frequency reversing requirements of the equipment. Contents of the invention [0004] The purpose of the present application is to provide a hydraulic reversing valve, which can meet the working requirements of high-pressure working environment and high reversing frequency. [0005] Another object of the present application is to provide a hydraulic reversing device, which includes the above-mentioned hydraulic reversing valve, which can also meet the working requirements of high-pr...
