Abstract

The invention discloses a hydraulic reversing valve, which comprises a valve body (1), a valve core (2) arranged in the valve body (1) in a rotatable manner and an operating rod (3) for driving the valve core (2) to rotate in the valve body (1), wherein a hollow cavity and at least three first oil feed holes (21) are formed in the valve core (2); at least two second oil feed holes (4) are formed in the valve body; and any one of the first oil feed holes is selectively connected with or disconnected from any one of the second oil feed holes (4) through rotation of the valve core (2). The operating rod drives the valve core to move, so that switching among at least six oil paths is realized, and the structure is simple. The invention also discloses a hydraulic transmission system comprisingthe reversing valve.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a reversing valve used in a hydraulic transmission system. The present invention also relates to a hydraulic transmission system comprising the above-mentioned reversing valve. Background technique [0002] Hydraulic transmission is a transmission method that uses liquid as the working medium to transmit energy and control. Hydraulic transmission has the advantages of simple structure, large output power, and easy realization of frequent reversing, and is widely used in various fields of production and life. [0003] The hydraulic transmission system mainly includes power components such as hydraulic pumps, actuators such as hydraulic cylinders or hydraulic motors, control components such as directional control valves, and auxiliary components such as fuel tanks. It is used to convert the hydraulic energy of the pressure oil into mechanical energy, and the control element is ...
