The present invention discloses a kind of electrohydraulic servo valve bourdon tube, and the bourdon tube is door type structure, and one-sided thickness 0.8mm, material is GH2132 high temperature alloys.The electrohydraulic servo valve bourdon tube of the present invention uses door type structure, the preferred 0.8mm of one-sided thickness, material selection yield strength and lasting, creep strength height, and the GH2132 high temperature alloys with preferable working plasticity, both torque-motor rigidity value requirement had been can guarantee, avoid simultaneously thin-walled form bourdon tube not vibration resistance, it is not antifatigue the defects of, the service life of electrohydraulic servo valve can be increased substantially, and processing technology is high.
Description
Technical field
The invention belongs to electrohydraulic servo valve technical field more particularly to a kind of electrohydraulic servo valve bourdon tubes.
Background technology
Electrohydraulic servo valve is the key element in electro-hydraulic servo control, be it is a kind of receive analog electrical signal after, it is corresponding to export
Modulate flow and the hydraulic control valve of pressure.Electrohydraulic servo valve has the advantages that dynamic response is fast, control accuracy is high, extensive
In electrohydraulic servo-controlling system applied to fields such as Aeronautics and Astronautics.In the design process of electrohydraulic servo valve, torque-motor
Bourdon tube in component is elastic element, provides support and transmits torque effect, the vibration resistance of bourdon tube, fatigue resistance are shadows
Ring the key factor in electrohydraulic servo valve service life.At present, bourdon tube is generally tubular structure, walled thickness 0.06mm or so, generally
Using 3J1 austenite precipitation strength type high resiliency Precise Alloys or C17200 beallons.But in vibration magnitude and alternating download greatly
Under lotus effect, existing bourdon tube is easily ruptured and is broken, and limits the service life of electrohydraulic servo valve.
Invention content
In view of the above situation of the prior art, the object of the present invention is to provide a kind of electrohydraulic servo valve bourdon tube, the present invention
Electrohydraulic servo valve bourdon tube vibration resistance, antifatigue, so as to improve the service life of electrohydraulic servo valve.
The above-mentioned purpose of the present invention is realized using following technical solution：
A kind of electrohydraulic servo valve bourdon tube, the bourdon tube be door type structure, 0.6~1.0mm of one-sided thickness, preferably
0.8mm。
Further, the material of the bourdon tube is GH2132 high temperature alloys.
The electrohydraulic servo valve bourdon tube of the present invention is using door type structure, one-sided thickness 0.8mm, further material selection
Yield strength and lasting, creep strength height, and the GH2132 high temperature alloys with preferable working plasticity, both can guarantee power
Square motor rigidity value requirement, while avoid thin-walled form bourdon tube not vibration resistance, it is not antifatigue the defects of, can significantly carry
The service life of high electrohydraulic servo valve, and processing technology is high.

Specific embodiment
In order to be more clearly understood that the objectives, technical solutions, and advantages of the present invention, with reference to the accompanying drawings and embodiments, to this
Invention is further elaborated.
Fig. 1 schematically illustrates a kind of structure of the electrohydraulic servo valve torque-motor component of bourdon tube using the present invention.Such as
Shown in Fig. 1, bourdon tube torque-motor component mainly includes upper and lower magnetizer 3 and 6, permanent-magnet steel 5, bourdon tube 2, armature 4, line
Coil assembly (not shown), motor shell 1 etc..Wherein, door type bourdon tube 2 is mounted on motor shell 1, door type bourdon tube 2
One-sided thickness can be 0.6~1.0mm, preferably 0.8mm.In 2 outer periphery of door type bourdon tube, upper and lower magnetic conduction is installed
Body 3 and 6 and the permanent-magnet steel 5 being arranged between upper and lower magnetizer 3 and 6, armature 4 be mounted on door type bourdon tube 2 it
Interior, coil block (not shown) is wrapped on armature 4.
In embodiment, the material of door type bourdon tube 2 uses GH2132 high temperature alloys.The material is a kind of elastic material
Material has high yield strength and lasting, creep strength, and with preferable working plasticity below 650 DEG C, can be further
Ensure the requirement of torque-motor rigidity value, improve vibration resistance, fatigue resistance, and processing technology is high.Certainly, the material of bourdon tube 2
Material can also be other materials, such as the material generally used at present.
When motor coil input control electric current, armature 4 generates a power under control magnetic flux and permanent magnet flux interaction
Square promotes armature 4, bourdon tube 2 to deflect a low-angle for being proportional to torque.The structure of bourdon tube is electrohydraulic servo valve design
Key, it is elastic element, provides support and transmits torque effect, can deflect certain angle when torque-motor is powered, break
When electric, original position can be restored to.
The bourdon tube of the present invention both can guarantee rigidity value requirement, together using door type structure, 0.6~1.0mm of one-sided thickness
When avoid thin-walled form not vibration resistance, it is not antifatigue the defects of., so as to improve the service life of electrohydraulic servo valve.
Although above by taking the bourdon tube torque-motor component of structure shown in Fig. 1 as an example, the spring of the present invention has been illustrated
Pipe.But, bourdon tube of the invention is not limited to the bourdon tube torque-motor component applied to above structure, it is clear that also applicable
In the bourdon tube torque-motor component with other structures, if wherein bourdon tube exist not vibration resistance, it is not antifatigue the problem of.
