The invention discloses a switchable multi-channel reversing rotary valve in the integral serial-parallel connection. The switchable multi-channel reversing rotary valve comprises two rotary reversing devices, a switching device and a valve body. Each rotary reversing device comprises a first valve core, a valve sleeve, a first end cover and a second end cover. The switching device comprises a second valve core, a third end cover and a fourth end cover. The first valve core is provided with a first boss and a second boss. Grooves 1 are formed in two end faces of each boss. The valve sleeves where the grooves 1 exist are provided with corresponding valve sleeve windows. The second valve core is provided with a groove 2, a first runner and a second runner. A plurality of oil openings and oil channels are formed in the valve body for communication with an oil way. The switchable multi-channel reversing rotary valve has the advantages that two rotary reversing devices are integrally arranged on the valve body and used for controlling two execution mechanisms to move, and by controlling the switching device, connection of the rotary reversing devices switches between the serial connection and the parallel connection.
Description
technical field [0001] The invention relates to a hydraulic reversing device, which is mainly used in the engineering technical field of integrating two rotary reversing devices on one valve body and controlling the movement of two actuators. Background technique [0002] A rotary valve refers to a valve that controls the on-off and reversing of the oil circuit through the rotation of the spool, and is used to control the action of the actuator. The current rotary valve has only one spool in a valve body, that is, only one rotary reversing device, and can only control the action of one actuator. Usually, it is necessary to control the actions of multiple actuators in engineering, so a corresponding number of rotary valves and corresponding hydraulic system oil circuits and hydraulic components need to be equipped. The current multi-way slide valve has multiple spools in one valve body, that is, multiple reversing devices, which can control the actions of multiple actuators,...
