A throttle hole (102) is formed in the rotary plate (1). A shaped hole (201) is formed in the flow valve (2). The throttle hole (102) and the shaped hole (201) are located in the same circumference with the axis of the rotary plate shaft (101) as the circle center. According to the rotary plate flow control mechanism, the control principle is simple, and the structure is compact. The dimension allowance of the rotary plate and the dimension allowance of the flow valve are large, and the product dimension can be effectively controlled. The manufacturing materials of the rotary plate and the flow valve are extensive, and the self weight of a product can be reduced easily. The rotary plate and the flow valve are simple in structure, machining is convenient, material consumption is small, and the production cost can be effectively reduced.
Description
Technical field
The invention belongs to field of hydraulic control, particularly to a kind of rotating plate flow control mechanism.
Background technology
Current flow control mechanism is mainly valve lining mechanism as shown in Figure 1, valve is promoted to be axially moveable under hydraulic coupling with spring force combined effect, until hydraulic coupling and spring force reach new stress balance state, valve position stability, obtaining stable discharge characteristic, therefore valve lining mechanism response speed is slower.Valve lining mechanism produces to move axially because of valve, and therefore this mechanism is generally axially larger in size.Lining and the processing of valve part need to ensure the requirements such as higher axiality, surface roughness simultaneously, manufacturing cost certainly will be increased.When using under the relatively bad working environments such as vibration, impact, it is easy to the serious problems such as valve clamping stagnation, spring breakage occur, affect the reliability of valve lining mechanism work.
Summary of the invention
It is an object of the invention to: improve the axial dimension that valve lining mechanism is longer, it is possible to make flow control device miniaturization, be beneficial to product to lightness, miniaturization.
Technical solution of the present invention provides a kind of rotating plate flow control mechanism, including rotating plate 1 and flow valve 2, the center that described rotating plate 1 is connected to described flow valve 2 by rotating plate axis 101 can circumferentially rotate around described rotating plate axis 101, described rotating plate 1 has throttle orifice 102, having type hole 201 on described flow valve 2, described throttle orifice 102 is positioned on the same circumference being the center of circle with rotating plate axis 101 axle center with described type hole 201.
Preferably, described throttle orifice 102 is open strip, it is arranged at rotating plate side, during throttling, described rotating plate 1 circumferentially rotates around described rotating plate axis 101, hides described type hole 201, described throttle orifice 102 overlaps gradually with described type hole 201, what described throttle orifice 102 was not covered with described type hole 201 is formed in part with effect passage section, and when described type hole 201 is completely covered, described throttle orifice 102 keeps minimum effective passage section and expands adjusting angle.
The invention have the advantage that control of product principle of the present invention is simple, compact conformation.Rotating plate is big with flow valve accessory size nargin, it is possible to effectively control product size.It is extensive that rotating plate and flow valve manufacture material, is conducive to reducing product deadweight.Rotating plate and flow valve simple in construction, easy to process, material consumption is few, can effectively reduce production cost.Rotating plate in the present invention and flow valve contact area relatively valve lining mechanism are greatly decreased, it is possible to effectively reduce the clamping stagnation because the factors such as pollutant cause, improve reliability and the service life of product.

Detailed description of the invention
In order to meet the electromotor user demand in aircraft flight each stage, engine calls fuel oil supplies according to certain rule.Electromotor is when takeoff condition, and in order to obtain peak power, fuel demand amount is big；Electromotor is when cruising condition, for ensureing the economy of flight, it is necessary to regulate fuel consumption to minimum.Therefore the fuel demand according to electromotor, regulates fuel supply volume and is to ensure that the key that engine stabilizer works.
Rotating plate flow control mechanism is capable of the control that engine fuel is accurate, stable.Its operation principle is that throttle lever links with rotating plate 1, and when rotating plate 1 rotates to left figure position in Fig. 2, throttle orifice 102 does not cover flow valve 2 type hole 201, and rotating plate 1 is in not throttle；When rotating plate 1 shielded type hole 102, for instance when rotating to right figure position in Fig. 2, rotating plate 1 is in throttle.
According to flow control principle, under pressure reduction controlled condition, circulation area is certain, and flow is certain.When aircraft is in cruising condition, fuel demand amount is little.If rotating plate 1 place is without throttle orifice 102, for reaching the circulation area needed, type hole 201 is almost all covered shown in figure as left in Fig. 3, if the anglec of rotation of rotating plate 1 slightly changes, angle [alpha] in figure as left in Fig. 3, exists the risk in closed type hole 201, jeopardize flight safety.If opening throttle orifice 102 at rotating plate 1 place, when low discharge state, still can change rotating plate 1 rotational angle and controlling engine oil amount, be beneficial to engine stabilizer and work shown in figure as right in Fig. 3.Being significantly greater than angle [alpha] by angle beta in the right figure of Fig. 3, namely fading to flow in minimum discharge is in zero process, and the rotating plate 1 with throttle orifice 102 needs to rotate bigger angle could realize thorough closed type hole 201.In order at utmost realize the stability that engine fuel controls, rotating plate 1 place must have throttle orifice 102.The schematic three dimensional views of rotating plate flow control mechanism is as shown in Figure 5.
The fuel regulator of piston 9 electromotor adopts rotating plate flow control mechanism as shown in Figure 5 to control engine fuel quantity delivered.When flight status changes, throttle control arm rotates, high-altitude regulates rotating plate 3 and fuel-flow control rotating plate 5 rotates and links simultaneously, changes high-altitude respectively and regulates the circulation area of the rotating plate 3 circulation area with high-altitude adjusting oil mass valve 7 and fuel-flow control rotating plate 5 and oil mass valve 6.Fuel oil flows into high-altitude from inlet connector 9 through main fuel tap 8 and defecator and regulates rotating plate 3, is divided into two-way by high-altitude adjusting oil mass valve 7.Wherein a road flows into oilhole 1；Another road fuel oil flows into oil mass valve 6, flows into oil circuit 2, oil circuit 1 and oil circuit 2 co-controlling through fuel-flow control rotating plate 5 and leads to the consumption of combustor.
