Abstract
The invention belongs to the field of airplane fuel system design and relates to a corrugated pipe valve assembly for an airplane fuel regulator. The corrugated pipe valve assembly is characterized by being composed of a valve (1), a corrugated pipe (2) and a connecting base (3). The corrugated pipe valve assembly improves the regulation precision of the fuel regulator and meets the requirement for high-precision regulation of the airplane fuel regulator.
Description
Technical field
The invention belongs to aircraft fuel system design field, relate to a kind of ripple in aircraft fuel oil actuator
Stricture of vagina pipe valve assembly.
Background technology
The current valve in aircraft fuel oil actuator is typically elastic as offer with spring or rubber etc.
The reset element of power.Spring or rubber are as providing elastic force reset element, and the elasticity of spring and rubber is stagnant
Rear property is relatively big, though the range of accommodation provided is big, but precision is low, it is impossible to meet aircraft fuel oil actuator high accuracy
The requirement of regulation.
It is an object of the invention to: provide a kind of corrugated tube valve in aircraft fuel oil actuator, in order to carry
Top adjustment precision, meets the requirement of aircraft fuel oil actuator high accuracy regulation.
The technical scheme is that 1, a kind of corrugated tube valve assembly for aircraft fuel oil actuator, its
It is characterised by: it is made up of valve 1, corrugated tube 2 and connection base 3；Valve 1 has Step Shaft profile,
Left section of shaft diameter of valve 1 is less than right section of shaft diameter, and left section of axle of valve 1 inserts the right output port of corrugated tube 2
In and be welded as entirety；Connecting base is a cylinder with Step Shaft profile, is from left to right divided into 4 sections,
1st section is left-hand thread section from left to right, and the 2nd section is outer six side's sections, and the 3rd section is right-hand thread section, and the 4th section is light
Cylinder section；Left-hand thread section external diameter is less than outer six side's section external diameters, and right-hand thread section external diameter is less than outer six side's section external diameters, light
Cylinder section external diameter is less than right-hand thread section external diameter；The left port of light tube section insertion corrugated tube 2 is interior and is welded as entirety；
The Effective wave number of corrugated tube 2 is 6～12.
The invention have the advantage that and provide a kind of corrugated tube valve in aircraft fuel oil actuator, improve
Degree of regulation, meets the requirement of aircraft fuel oil actuator high accuracy regulation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below the present invention is described in further details.See Fig. 1, a kind of for aircraft fuel oil actuator
Corrugated tube valve assembly, it is characterised in that: it is made up of valve 1, corrugated tube 2 and connection base 3；Valve
1 has Step Shaft profile, and left section of shaft diameter of valve 1 is less than right section of shaft diameter, and left section of axle of valve 1 inserts
The right output port of corrugated tube 2 is interior and is welded as entirety；Connecting base is a cylinder with Step Shaft profile,
From left to right being divided into 4 sections, the 1st section is left-hand thread section from left to right, and the 2nd section is outer six side's sections, and the 3rd section is right
Thread segment, the 4th section is light tube section；Left-hand thread section external diameter is less than outer six side's section external diameters, and right-hand thread section external diameter is little
In outer six side's section external diameters, light tube section external diameter is less than right-hand thread section external diameter；Light tube section inserts the left end of corrugated tube 2
Mouth is interior and is welded as entirety；The Effective wave number of corrugated tube 2 is 9.
The wall thickness of corrugated tube 2 is 0.1mm～0.2mm, and the internal diameter of corrugated tube is 6mm～8mm, corrugated tube 2
External diameter is 9mm～10mm.
Corrugated tube 2 is manufactured by 1Cr18Ni9Ti rustless steel.
The operation principle of the present invention is: the present invention is a kind of corrugated tube valve in aircraft fuel oil actuator
Assembly, corrugated tube valve assembly uses the mode of welding to be attached, it is ensured that corrugated tube valve assembly airtight
Property, connecting the external screw thread precision height that base has, during assembling, corrugated tube valve installation site can carry out precision
Adjust；When corrugated tube valve assembly chamber pressure changes, corrugated tube produces elongation or compression, valve
Corrugated tube axis direction produces displacement；The reset of fuel regulator is provided by the change in displacement of valve
And high accuracy output.
Embodiment
The wall thickness of corrugated tube 2 is 0.11mm, and the internal diameter of corrugated tube is 6.5mm, and the external diameter of corrugated tube 2 is 9.5
mm.Corrugated tube 2 is manufactured by 1Cr18Ni9Ti rustless steel.Valve 1, corrugated tube 2 and connect base 3 by
1Cr18Ni9Ti rustless steel manufactures, it is simple to the integral solder of assembly, it is ensured that the air-tightness of corrugated tube valve assembly
Requirement.
