Abstract
A single-cycle and hydraulic control change valve is characterized by comprising a change valve body, a change valve core, a change valve hydraulic control cover, a sing-cycle controller, a control oil inlet channel and a single-cycle oil return channel. The single-cycle and hydraulic control change valve has the advantages that when the change valve works, control oil enters the change valve hydraulic control cover to control movement of the change valve core through the control oil inlet channel and the single-cycle controller on the change valve hydraulic control cover, and meanwhile seals the single-cycle oil return channel completely. When the change valve does not work, the single-cycle oil return channel is communicated with an inner cavity of the change valve hydraulic control cover and an oil tank. The single-cycle and hydraulic control change valve achieves one-way cycle of the control oil of the hydraulic control change valve, reduces pollution of a hydraulic system by return oil, and have a washing effect on the hydraulic system.
