Specific implementation mode
As shown in Figure 1, a kind of low energy consumption flow automatic control device of the embodiment of the present invention, including：Fuel tank 1, constant displacement pump
4, speed governing valve 10 and electromagnetic relief valve 7；Wherein, fuel tank 1 is internally provided with built-in filter 2, and external filter 3 is arranged in fuel tank
Outside 1, built-in filter 2 is connect with constant displacement pump 4.The setting of speed governing valve 10 is connect inside stuffing apparatus with constant displacement pump 4, speed governing valve
10 reduce flow system flow for forcing.Electromagnetic relief valve 7 be arranged the outlet of hydraulic pump be connected to constant displacement pump 4 and speed governing valve 10 it
Between, electromagnetic relief valve 7 is used for regulating system pressure.Constant displacement pump 4 is connect with motor 5, is installed between constant displacement pump 4 and speed governing valve 10
There is check valve A6, pressure gauge 8 and check valve B9 are also equipped between constant displacement pump 4 and speed governing valve 10, stream is installed on speed governing valve 10
Measure stop valve 11.
The characteristics of according to Weapon Hydraulic System is loaded, oil sources use big flow constant displacement pump, can meet the big flow need of system
It asks.An overflow valve is provided with as safety valve in hydraulic pump outlet, and system pressure is adjusted by overflow valve.Check valve will
Constant displacement pump and control valve separate, to realize safe and reliable operation.Speed governing valve is the flow-rate control section of stuffing apparatus, can be forced
Flow system flow is reduced, realizes deceleration.The characteristics of according to Weapon Hydraulic System is loaded, oil sources use big flow constant displacement pump, can
Meet the big flow demand of system.An overflow valve is provided with as safety valve in hydraulic pump outlet, and system pressure passes through overflow
Valve is adjusted.Check valve separates constant displacement pump and control valve, to realize safe and reliable operation.Speed governing valve is stuffing apparatus
Flow-rate control section can be forced to reduce flow system flow, realize deceleration.
Present invention employs built-in filters and external filter, improve the cleannes of fluid, reduce the dirt of system
Dye is conducive to the service life for improving system element.Built-in filter mainly cleans fluid, it is ensured that component is not contaminated, does not block up
Plug, external filter mainly by pressure carry out fluid cleaning, it is ensured that fluid entirety it is not contaminated.
The present invention uses electromagnetic relief valve and pressure gauge, improves the reliability of system, it is ensured that the pressure of system is certain
In range, while the spillway discharge of system can be reduced, reduce energy consumption.By pressure gauge, can monitoring system in real time pressure
Value adjusts electromagnetic relief valve, and it is zero that can make the pressure reduction of system rapidly, while reducing spillway discharge, reduces energy consumption.When excessive
