This kind of valve plays an important role in the hydraulic support equipment of coal mine machinery. The difference between hydraulic control one-way valve and common one-way valve is that there is an additional control oil circuit. When the control oil circuit is not connected to the pressure oil, the hydraulic control one-way valve works like a common one-way valve. The pressure oil flows only from the inlet to the outlet and cannot flow backwards. When there is a control pressure input in the control oil circuit, the piston top rod moves to the right under the action of pressure oil, and the one-way valve is jacked by the top rod to connect the inlet and outlet.

Hydraulic one-way valve is a valve that can make one-way valve flow backwards by controlling fluid pressure. This kind of valve plays an important role in the hydraulic support equipment of coal mine machinery. The difference between hydraulic control one-way valve and common one-way valve is that there is an additional control oil circuit. When the control oil circuit is not connected to the pressure oil, the hydraulic control one-way valve works like a common one-way valve.

When there is a control pressure input in the control oil circuit, the piston top rod moves to the right under the action of pressure oil, and the one-way valve is jacked by the top rod to connect the inlet and outlet. If the oil outlet is larger than the oil inlet, the oil can flow backwards.
