Hydraulic Check Valve Works
Hydraulic check valve is by controlling fluid pressure, you can make the check valve reverse circulating valve. This valve of hydraulic support in coal mine machine equipment plays an important role. Hydraulic check valve common valve difference k is a control circuit, when control pressure oil circuit not connected fluid, hydraulic check valve just like regular one-way valves, pressure oil flow from inlet to outlet, not reverse flow. Control oil pressure oil control input, the piston rod in the presence of the pressure oil moves, pole top check valve, the oil inlet and outlet connection. If outlet than inlet reverse flow of oil.
