What is hydraulic overload protection valve
Another name for the relief valve. However, unlike the safety valve, it is connected to the working chamber, divided into double overload and single overload (both working chambers are connected to the overload valve and one working chamber with overload valve).
Simply put a pressure to protect the valve, used to stabilize the working pressure of the hydraulic system to protect the hydraulic pipes and hydraulic components from high pressure and damage. When your work pressure is set to 10, if the pressure of the hydraulic oil is greater than 10 when you work, then the valve will open itself, let the pressure overflow from here, when the pressure will automatically shut down when restored.
If the A cavity is the oil chamber, the overload valve connected to it, then the overload valve to protect the working pressure of the cavity, when the external load (if the crane lift the weight) to achieve overload protection valve set pressure, overload protection The valve will open and release the pressure. Play a role in protecting the hydraulic system.
