Overflow throttle valve is also a pressure compensation type throttle valve, which consists of relief valve 3 and throttle 2 in parallel. Imported high-pressure oil p1, part of the throttle valve 2 to the implementing agencies, the pressure drop p2, the other part of the relief valve 3 overflow port to the tank. Overflow valve, the lower end of the throttle valve before and after the pressure oil p1 and p2 connected. When the outlet pressure p2 increases, the valve spool down, off a small overflow port, overflow resistance increases, the inlet pressure p2 then increases, so the throttle before and after the pressure difference (p1-p2) remained unchanged; vice versa. That is, the flow through the valve is basically unaffected by the load. Unlike speed control valves, relief valves must be connected to the intake of the actuator. At this time the pump outlet (ie overflow throttle inlet) pressure p1 changes with the load pressure p2 changes, is a transformer system, the power utilization is more reasonable, the system heat is small.
