Classification and preventive measures of liquid control check valves
2023-11-23
A liquid-controlled check valve is a valve that relies on controlling fluid pressure to reverse the check valve.This valve has a more important position in the hydraulic support equipment of coal mining machinery.It is a more controlled oil channel with a normal check valve.When the control oil is not connected to the pressure oil, it can act like a normal check valve, and the pressure oil only flows from the oil port to the outlet.Cannot flow in reverse.When there is a control pressure input in the control oil path, the piston rod moves to the right under the pressure oil, and the check valve is opened with the top rod to rotate the inlet and outlet.If the oil change port is larger than the oil port, the oil can flow in reverse.
