Abstract
The present invention relates to governor valve, in particular to a kind of wide scope allocation proportion governor valve.The valve includes import, first outlet and second outlet, passes through the flow of motor adjustment two outlets of spool.The wide scope that the structure realizes proportion adjustment valve is adjusted.
Description
Technical field
The present invention relates to governor valve, in particular to a kind of wide scope allocation proportion governor valve.
Background technique
With aviation industry development to the low oil consumption of aircraft, low pollution require raising, in order to meet the low oil consumption of aircraft and
The requirement of low pollution, modern Civil Aviation Engine combustion chamber generally use the modes such as polycyclic chamber, multistage combustion and improve efficiency of combustion, drop
The discharge of low pollution object.As the development of combustion technology gradually increases the variation of fuel distribution policy requirement, multiple fuel allocation proportion
Degree of regulation it is higher and higher, adjustable range Yi Yuelai wide has exceeded the allocation proportion range of nozzle characteristic.It needs thus
It designs a kind of wide allocation proportion and adjusts distribution valve to meet the needs of engine fuel distribution.
Summary of the invention
Present invention solves the technical problem that: a kind of wide scope allocation proportion governor valve is provided.
Technical solution of the present invention: a kind of wide scope allocation proportion governor valve, the valve include import, first go out
Mouth and second outlet pass through the flows of motor adjustment two outlets of spool.The structure realizes the wide model of proportion adjustment valve
Enclose adjusting.
Preferably, gap is provided between bushing and shell, the gap includes at least two parts, and a part of gap is formed
Hold the cavity of oil, another part and gap, which are small enough to be formed between bushing and shell, to be sealed；Perforation is provided on spool up and down
The hole of end face is provided with connection spool upper space on bushing and holds the hole of oil cavity.On the one hand the structure reduces import
Flow resistance, on the other hand ensure that the flow of spool bottom space when import is closed.

Specific embodiment
The specific embodiment of the invention is described in further details below, system is completed by the valve schematic diagram of the invention
It makes, practice have shown that distribution valve function, performance are met the requirements, referring to attached drawing.Specific embodiment is as follows:
Valve working principle: distribution valve spool 1 and piston 3 are electro-hydraulic by the screw thread realization Hard link on LVDT measuring staff 6
Servo valve 7 receives EEC signal control fuel distribution valve piston driving spool and continuously moves, and LVDT measuring staff 5 is living by fuel distribution
Gate valve core location information passes to the side the LVDT side 6, LVDT of head head and position feedback is realized position-force control to EEC；
Fuel oil forms appearance oil pocket body region by 8 valve pockets and shell and enters in 2 valve pockets from valve pocket import 110 and import 213
Portion, 9 valve pockets and shell form clearance seal region, and import fuel oil is isolated with first outlet fuel oil, and fuel oil can only pass through 12 the
One outlet type hole is circulated to the first oil circuit；
11 second outlet type holes are circulated to by 13 spool oil-through holes behind fuel admission valve set inside；
The course of work is as follows:
A, first outlet allocation proportion reaches 100%:12 first outlet allocation proportion and reaches 100%, and 1 spool of control is located at
Least significant end, 11 second outlets are blocked completely by 1 spool, and fuel oil is formed by 8 valve pockets and shell holds oil pocket body region from valve pocket
10 imports of import 1 and 13 2 enter 2 valve pockets, are circulated to the first oil circuit by 12 first outlet type holes, as shown in Figure 7；
B, the intermediate shape that works of outlet one and the logical oil in outlet two: 1 spool of control is centrally located, fuel oil passes through 8 valves
Set is formed with shell holds oil pocket body region from 10 valve pocket of valve pocket import 1 and 13 imports 2 into valve pocket, passes through 12 first outlets all the way
Type hole is circulated to the first oil circuit, and another way is circulated to 11 second outlet type holes by 13 spool oil-through holes and is circulated to the second oil circuit,
The aperture that 12 first outlet type holes and 11 second outlet type holes are controlled by 1 valve core movement, moves upwards and turns down 12 first outlets
Type hole opens 11 second outlet type holes, and second outlet allocation proportion rises, otherwise decline, as shown in Figure 8；
C, second outlet allocation proportion reaches 100%:11 second outlet allocation proportion and reaches 100%, and 1 spool of control is located at
Top, 12 first outlets and 13 valve pocket oil-ins 2 are blocked completely by 1 spool, and fuel oil is formed by 8 valve pockets and shell holds oil
Cavity area enters 2 valve pockets from 10 valve pocket imports 1, is circulated to 11 second outlet type holes to the second oil by 13 spool oil-through holes
Road, as shown in Figure 9.
