Be connected to drainback passage, return check valve is mounted on inside upper housing, opened up in lower case into, oil return hydraulic fluid port, oil inlet and outlet with
Engine fuel mouth is connected.
Compared with prior art, the remarkable advantage of the utility model are as follows: the utility model is designed reasonably, structure are simply tight
It gathers, is light-weight；Spool valve pocket uses the conical design of wide arc gap, not only ensure that flow area, also improves the antipollution of valve
Ability；Spool uses step motor control, and available digital model directly carries out opened loop control, and displacement is corresponding with input pulse number,
Step pitch error not long-term accumulation high reliablity, easily starts up, stops, positive and negative rotation control and speed change respond, and stops having self-locking
Ability.
Detailed description of the invention
Fig. 1 is the utility model small-size turbojet engine fuel control system fuel regulator valve structure chart.
Specific embodiment
In conjunction with Fig. 1, a kind of small-size turbojet engine fuel control system fuel regulator valve, by stepper motor 1, upper housing
5, lower case 8, gear 2, ball-screw 3, spool 6, valve pocket 7 and return check valve 4 form；
The stepper motor 1 is mounted on upper housing 5, and stepper motor 1 is driven with ball-screw 3 by two gears 2
Dynamic, ball-screw 3 is mounted in the big stomidium of spool 6, and the sealing ring on ball-screw 3 is separated in-line and gear 2, valve
6 small end of core is inserted into 7 inner hole of valve pocket, and spool 6 constitutes variable restrictor window with valve pocket 7 and separates oil suction chamber and A chamber, A chamber oil
Liquid is connected to by return check valve 4 with drainback passage, and return check valve 4 is mounted on inside upper housing 5, opened up in lower case 8 into,
Oil return hydraulic fluid port, oil inlet and outlet are connected with engine fuel mouth.Wherein A chamber is the cavity that upper housing 5 surrounds, and connects drainback passage
And oil suction chamber.
6 small end of spool includes that one section of cylindrical body and a Duan Yuantai, rotary table are relatively large in diameter one end and connect with cylindrical body, directly
The smaller one end of diameter is protruded into valve pocket 7；Rotary table periphery is evenly arranged with more than two grooves；Variable restrictor window is by spool small end
On groove and valve pocket composition, be moved forward and backward by spool and change groove and valve pocket relative position, to change variable restrictor window
Mouth size.
Further, depth of groove reduces as rotary table diameter increases.Alternatively, depth of groove increases with rotary table diameter
And increase.
Working principle of the utility model is: the pwm signal control stepper motor of input realizes positive and negative rotation, stepper motor is logical
Crossing gear drives ball wire rotation to realize the control to spool displacement, logical between spool and valve pocket when spool is protruding
Flow area gradually decreases, and recirculating oil quantity is reduced, when reaching limit outside spool, flow area choke-out.Otherwise when spool retracts
Flow area between spool valve pocket is gradually increased, and recirculating oil quantity increases, and flow area reaches maximum when spool limits.
The fuel regulator valve of the utility model drives valve core movement by stepper motor, realizes flow control, can be applied to
The flow control of small-size turbojet engine main fuel feed or bypass fuel control.System has control precision height, contamination resistance
By force, the advantages of high reliablity.
The utility model is described in detail below with reference to embodiment.
Embodiment
With reference to attached drawing 1, small-size turbojet engine fuel control system fuel regulator valve, by stepper motor 1, upper housing 5,
Lower case 8, gear 2, ball-screw 3, spool 6, valve pocket 7, return check valve 4 form.Stepper motor 1, rolling are installed on upper housing 5
Ballscrew 3, gear 2 are separately mounted on the output shaft of stepper motor 1 and the output shaft of ball-screw 3, and 6 big end of spool opens up interior
Hole screw thread is connect with ball-screw, and 6 small end of spool is inserted into the inner hole of valve pocket 7, and spool 6 and valve pocket 7 divide oil suction chamber and A chamber
