Relief valve effect

The role of relief valve relief valve used to control the pressure in the system is basically constant, to achieve regulation, pressure regulation or pressure limiting, its main role is reflected in two aspects: First, in the metering pump throttling speed control system to Keep the outlet pressure of the hydraulic pump constant, and overflow the excess oil pump back to the tank, then the relief valve from the pressure and overflow; second, play a safety role in the system, the normal hydraulic system when the relief valve In the closed state, only when the system pressure is greater than or equal to the set pressure when the pressure relief valve opens, so that the system pressure is no longer increased, the system overload protection.
