4WEH-16E72 Rexroth Safety Relief Valve with Blue Color Concrete Pump Truck Fittings
The working principle and composition of the relief valve of the pump truck
The relief valve of the pump truck is a hydraulic control type
pressure regulator, which controls the pressure and flow of the
system by adjusting the opening of the relief valve port to achieve
the effect of protecting the system, realizing braking, preventing
the overload of the hydraulic system, eliminating the peak pressure
of the hydraulic system, etc. The relief valve of the pump car is
composed of the valve body, the adjusting element in the valve, the
relief valve core, the pressure relief unloading valve and the
pressure relief valve core.
Second, the role of the relief valve of the pump car
1. Control the pressure and flow of the hydraulic system: when the
pressure in the hydraulic system reaches the set value, the relief
valve of the pump car will automatically open to limit the pressure
in the hydraulic system and protect the system from overload or
overpressure damage.
2. Prevent the peak pressure of the hydraulic system: When the
movement of the actuator is over, the relief valve of the pump car
can also be opened by opening the relief valve port to rapidly
reduce the pressure in the hydraulic system, avoid the peak
pressure caused by inertia and other factors, and protect the
hydraulic system from damage.
3. Realize braking and unloading: In the emergency or shutdown
state, the relief valve of the pump car can play the role of
braking or unloading, and quickly reduce the pressure in the
hydraulic system to achieve the stability of the frame and the
rapid unloading of the actuator.
4. Adjust the flow of the system: the relief valve of the pump car
can also adjust the hydraulic flow in the system by changing the
opening of the valve port to meet the needs of different working
states.
