The hydraulic control one-way valve is a valve that can reverse flow through the one-way valve by controlling the fluid pressure.
This valve occupies an important position in the hydraulic support equipment of coal mining machinery.
The difference between the hydraulic control one-way valve and the ordinary one-way valve is that there is an additional control oil passage K. When the control oil passage is not connected to pressure oil,
The hydraulic control one-way valve works like an ordinary one-way valve, with pressure oil flowing only from the oil inlet to the oil outlet, and cannot flow in reverse.
When there is a control pressure input in the control oil circuit, the piston rod moves to the right under the action of pressure oil. Use the rod to open the one-way valve and connect the oil inlet and outlet. If the oil outlet is larger than the oil inlet, the oil can flow in the opposite direction.
