Description
Technical field
This utility model belongs to fluid transport system accessory field, be used primarily in fuel system, oil system or other
In low-pressure fluid induction system, it is specifically related to the flexible connecting member of a kind of low-pressure fluid induction system English system conduit.
Background technology
Aerospace equipment and the fuel system of other plant equipment, oil system and other low-pressure fluid induction systems are big
Amount uses English system pipe；Pipe made in Great Britain in inches, and general standard is ips, such as: 1/2 ", 3/4 " etc..Now it mostly is
Seamed pipe, galvanized pipe and the pipe fitting matched therewith: elbow, threeway, plug etc., many employings are threaded, for low pressure
The conduit of pipeline imperial sizing uses threaded；Metric system pipe standards are external diameter × wall thickness, are generally used for seamless pipe, connected mode
Typically use welding.When using pipe made in Great Britain, in order to ensure that the reliable flexible between these conduits connects, design is needed to be suitable for
Connector.
A kind of clamping hoop type flexible connector connected for pipeline as disclosed in prior art CN201120569784.1,
Being provided with sleeve pipe, sleeve pipe has sealing ring, be cased with sleeve outside sleeve pipe, sleeve is outside equipped with clip, and clip is that two semi-rings pass through
The retractable structure of hinge-coupled, realizes fixing and release by latch hook.By clip compression sleeve, extrude close after sleeve deformation
Seal, makes sealing ring produce the purpose that deformation reaches to be tightly connected, but the sleeve pipe of above-mentioned technology is to use one-body molded knot
Structure, by clip compressional deformation amount big time just can play the purpose being tightly connected, this just require the material of sleeve pipe be elastic material or
The size of person's sleeve pipe must be supporting, needs customization to use, and sleeve pipe once damages and is difficult to find succedaneum, and this just gives and installs
Make troubles with use.
Utility model content
This utility model is intended to provide the flexible connecting member of a kind of general pipeline, to solve the connector of prior art to set
Material and the dimensional requirement of pipe are higher, and once damage the defect being just difficult to find that succedaneum.
The flexible connecting member of a kind of low-pressure fluid induction system English system conduit in this programme, including sleeve pipe, sealing ring, set
Cylinder and hoop component, sleeve pipe is connected by mechanical stitch mode with conduit, and described sleeve includes circular inner sleeve and two
Semicircular outer sleeve, one end of described sleeve pipe is provided with the female thread being connected with conduit, and the other end is provided with seal groove, described sealing
Circle is positioned at seal groove；Being matched in clearance between described sleeve pipe and inner sleeve, it is convex that described inner sleeve external rings is provided with a plurality of extruding
Bar, described hoop component is positioned at the outside of outer sleeve and for tightly pluging with molten metal sleeve.
Operation principle of the present utility model: use from internal mechanical rolling depression method by two conduits and two sleeve pipes securely
Link together, in the seal groove of two sleeve pipes having connected conduit, overlap sealing ring respectively, then by these two sleeve pipes
One be inserted in from two of inner sleeve, then two outer sleeves are stuck in outside inner sleeve, finally by hoop component overlap outside
Outside sleeve, being tightened by hoop component, hoop component extruding outer sleeve, outer sleeve produces the extruding of elastic deformation extruding inner sleeve
Raised line, makes inner sleeve also produce elastic deformation and then crush seal circle, makes sealing ring be extruded generation by inner sleeve certain
Decrement plays sealing function；Owing to having matched in clearance between sleeve pipe and inner sleeve, therefore conduit is permissible relative to inner sleeve
Tilt certain angle thus reach the purpose flexibly connected.
This utility model compared with prior art provides the benefit that: outside flexible connecting member of the present utility model is by two
The setting of the setting of sleeve, i.e. Split type structure, in the case of not using elastic material, also can guarantee that enough elastic deformations,
Requirement to size is the highest simultaneously, it is not necessary to matching used sleeve also can reach the effect being tightly connected, it is simple to finds replacement
Product are changed；When hoop component is to sleeve extruding, sealing ring is produced radial compression amount by radial pressure and seals, relative to domestic
The rubber seal of conventional catheter flexibility connector is produced axially and radially decrement sealing by axial compressive force and is more prone to real
Now seal；Sleeve pipe and conduit use mechanical stitch mode to link together from inside, the reliability of connection is higher, construction weight relatively
Gently, it is particularly suited for aerospace equipment.
Further, described hoop component includes open annular clip, bolt and self-locking nut, described open annular clip
Two ends are provided with connecting rod, and described connecting rod is provided with the bolt hole passed for bolt.By open annular hoop sleeve in outer sleeve,
By bolt is penetrated in bolt hole, tight a bolt and self-locking nut, hoop component is fastened on outside sleeve, to reach the company of sealing
The purpose connect.
Further, described casing inner diameter is more than catheter outer diameter.The physical dimension Aero-Space to be fully taken into account of sleeve pipe set
The all size imperial sizing conduit that standby and the fuel system of other plant equipment, oil system and other fluid systems are commonly used
External diameter and wall thickness, combine conduit maximum working pressure according to conduit size and determine the minimum of sleeve pipe overall dimensions, i.e. casing inner diameter
Dimension limit is greater than the maximum limit of size of catheter outer diameter so that can successfully be enclosed within conduit, and will be to each
The sleeve pipe of specification carries out Strength co-mputation by hydraulic pipe strength calculation formula.
Further, described sleeve pipe is duralumin, hard alumin ium alloy sleeve pipe.Mechanical stitch mode is used to be connected with conduit from inside sleeve pipe
Time together, sleeve pipe can be by the tension force outside from inside, and this just requires that sleeve pipe to have certain intensity, and navigates in general
Empty space equipment and the least maximum of operating pressure within the fuel system of other plant equipment, oil system are only
0.25MPa, typically selects duralumin, hard alumin ium alloy for alleviating weight；After requiring the material of pipe box to adapt with this material i.e. to contact
Do not produce stress corrosion, need duralumin, hard alumin ium alloy is carried out surface anodization process.
