Abstract

The invention provides an electromagnetic direct-push type reversing valve. The electromagnetic direct-push type reversing valve comprises a valve body, a first oil channel and a valve rod, wherein the first oil channel is arranged inside the valve body; the valve rod is used for controlling the first oil channel to be connected with a second oil channel or a third oil channel; the valve rod is used for controlling the second oil channel to be connected with a fourth oil channel or controlling the third oil channel to be connected with a fifth oil channel; the two ends of the valve rod are each provided with a solenoid valve; a push rod is arranged between the second oil channel and the third oil channel; the second oil channel is connected with a first oil hole through a first one-way valve; the third oil channel is connected with a second oil hole through a second one-way valve; the push rod is capable of opening the first one-way valve in a pushing manner when approaching to the second oil channel and is capable of opening the second one-way valve in a pushing manner when approaching to the third oil channel. The reversing valve provided by the invention is high in oil liquid pollution resistance and is capable of realizing stable flow output.

Description

technical field [0001] The invention relates to the technical field of reversing valves, in particular to an electromagnetic direct push reversing valve. Background technique [0002] In the hydraulic system, the reversing valve is one of the main components. We often need to implement the speed conversion of the actuator. As far as the existing hydraulic control device is concerned, it is generally solved by manually adjusting the flow valve, which is relatively complicated and the degree of automation is not high. [0003] At present, a pilot-operated proportional reversing valve has appeared on the domestic market. Its function is to combine the proportional reversing valve with the amplifier to drive the proportional electromagnet to push the valve core, that is, to control the direction and size of the liquid flow, and to provide accurate hydraulic pressure to the hydraulic system. traffic. However, the existing pilot-operated proportional directional control valve is...
