Working Principle of Hydraulic One-way Valve

Working Principle of Hydraulic One-way Valve：

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. Hydraulic one-way valve differs from ordinary one-way valve in that it has an additional control oil line K. When the control oil line is not connected to the pressure oil, the hydraulic one-way valve works like a common one-way valve. The pressure oil flows only from the oil inlet to the oil outlet and cannot flow backwards. When controlling the oil in the oil pipeline to control the pressure input, the piston top rod moves to the right under the action of the pressure oil, and the one-way valve is opened 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.
