Fuel oil pumping action be fuel oil from fuel tank be sucked out, pressurize after be transported in fuel feed pump and fuel pressure adjust
Certain fuel pressure is established in device cooperation.Fuel pump guarantees to supply lasting combustion to atomizer to oil distributing pipe conveying high-pressure fuel oil
Oil.
The safety valve used in conventional fuel pump is generally made of valve body, spool, spring etc..The unlatching pressure of safety valve
Power passes through the pressing force of spring and the compression area decision of spool, i.e. P=F/S.Because the design of safety valve off-load flow needs,
The compression area of its spool is substantially determining.That is under certain conditions, the pressing force of spring just decides safety
The cracking pressure of valve.When needing cracking pressure higher, the compression intensity of spring just needs bigger.And the pressure for requiring spring to provide
When tightly intensity is bigger, line footpath just needs overstriking.And thus bring consequence is, safety valve volume becomes larger, and opens flexibility ratio
It substantially reduces, manufactures difficulty and increase.
In fuel pump industry, the case where conventional safety valve structure also only can be suitably used for mesolow, small flow, high pressure,
It cannot achieve safety valve when big flow to be integrated on hydraulic pump, and its insensitive performance is also unable to satisfy precise hydraulic system
It is required that being easy to bring inconceivable adverse consequences to hydraulic system or even whole equipment.

Digital Control valve 45 is by setup pressure value, using valve body oil duct 50, control valve valve pocket 51, main valve lid 60, oil
Pressure difference between pressure chamber 64 and oil circuit screen pipe 66 realizes digitlization off-load control of the relief valve assembly 1 to fuel pump body 2
System.Input pressure chamber 64 is connected to the fuel-displaced high pressure chest of fuel pump body 2, and the two sides of this input pressure chamber 64 and flow nipple 65
It is connection, therefore each pressure at this time that the top of oil circuit screen pipe 66, valve body oil duct 50 and valve core of main valve 62, which passes through aperture,
It is worth 64=oil circuit of input pressure chamber screen pipe, 66=valve body, 50=main valve of oil duct lid 60.In the premise that Digital Control valve 45 is not opened
Under, 62 pressure at both sides of valve core of main valve is always consistent.Even if 64 pressure of input pressure chamber is high again, will not be opened.
When 64 pressure rise of input pressure chamber is to when being more than the setting pressure of Digital Control valve 45, control valve core 52 is pushed up
Oil pressure adjustment spring 54 is opened, is connected to the pressure chamber of valve body oil duct 50 and the unloading port of control valve valve pocket 51, while valve body oil duct
50, main valve lid 60, the rapid off-load of pressure chamber at control valve valve pocket 51 3, input pressure chamber 64 and oil circuit screen pipe 66 are because there is section
The throttling action of stem bar (65), pressure value at this time are (input pressure 64=oil circuit of chamber screen pipe 66) > (valve body oil duct 50=master
60=control valve of valve deck valve pocket 51).The input pressure chamber 64 of 62 two sides of valve core of main valve and the pressure of main valve lid 60 are inconsistent, at this time
Valve core of main valve 62 will open oil pressure adjustment spring 54, and digitlization main valve 47 is in the open state.
Digital Control valve 45 and digitlization main valve 47 on relief valve assembly 1 can be connected and be set with digital manipulations such as computers
Standby circuitry phase is connected to.Digital Control valve 45 also known as electric control valve pass through receiving in industrial automation process control field
The control signal of regulation unit output goes to change the techniques such as rate-of flow, pressure, temperature, liquid level ginseng by power operation
Several final control elements.Generally it is made of executing agency and valve.If press stroke feature, regulating valve can be divided into Direct Travel and
Angle stroke；By the power that its matched executing agency uses, pneumatic control valve, electric control valve, hydraulic adjusting valve three can be divided into
Kind；It is divided into linear characteristic by its function and characteristic, equal percentage characteristics and three kinds of parabolic characteristic.Regulating valve be suitable for air,
The media such as water, steam, various corrosive medias, mud, oil product.Operator is inputted by parameter, is realized to relief valve assembly 1
The design of pressure of upper Digital Control valve 45.
In conclusion the digitlization gas turbine high power fuel system, pressure control essence big with relief flow
Really, effectively impurity screening, good operation stability and long service life the advantages of.Its control method just can using lesser control valve
The opening and closing of effective control bound, and because of control valve and related oil circuit ingehious design, so that the spool of main valve,
The control of high pressure, big flow oil circuit can be realized using smaller intensity for spring etc..Fuel pressure stability is improved, guaranteed oil
It is smooth.
