Description
Technical field
The present invention relates to a kind of rotary Electric hydraulic pressure servo valves, predominantly output rated operating pressure.
Background technique
Electric hydraulic pressure servo valve is the critical elements of hydraulic system, and function is the electric signal for receiving control box output, output
Rated operating pressure.Currently widely used Electric hydraulic pressure servo valve is Dual Injector Baffle formula Electric hydraulic pressure servo valve, due to spray
Mouth and flapper gap only have 0.035~0.045mm, very sensitive to the cleannes of hydraulic oil, and there is contamination resistance differences
Disadvantage, often since pollutant blocking causes Electric hydraulic pressure servo valve failure, so as to cause aircraft lateral deviation.
Jetting type Electric hydraulic pressure servo valve processing technology is complicated, debugging is difficult, production efficiency is not high, Dual Injector Baffle formula electricity
Hydraulic coupling servo valve and jetting type Electric hydraulic pressure servo valve, which are used, is put by thin-walled bourdon tube as the hydraulic of resilient support members
Big device easily causes concussion in use, leads to thin-walled spring tracheal rupture, so that output pressure be caused to fail as prestage.
Summary of the invention
The purpose of the present invention: a kind of rotary Electric hydraulic pressure servo valve is provided.
Technical solution of the present invention: a kind of rotary Electric hydraulic pressure servo valve, it is characterized in that: the rotary electric is hydraulic
Force servo valve includes limited angle torque motor 1, shell 2, valve pocket 3, spool 4, turn of spool 4 and limited angle torque motor 1
Axis rigid connection is rotated with the shaft of limited angle torque motor 1, and in 3 force fit shell 2 of valve pocket, spool 4 is inserted into valve pocket
In 3；It is provided with annular groove 5 on the spool 4 and 3 output pressure window 8 of valve pocket is linked up, is provided with rectangular channel 6 and annular groove among spool 4
5 connections.
Oil entered window 7, oil return window 9 and output pressure window 8 are provided on the valve pocket 3.
It is wide that the distance between oil entered window 7 and oil return window 9 on the valve pocket 3 are less than 4 intermediate rectangular slot 6 of spool
Degree.
The oil entered window 7 and oil return window 9 is rectangular configuration.
Beneficial effects of the present invention: eliminating traditional servo valves prestage hydraulic amplifier, avoids traditional thin-walled spring
The possibility of tracheal rupture, increases structural strength, has that structure novel, contamination resistance be strong, dynamic height, simple process, reliability
High advantage.
