Description
Technical field
The invention belongs to fluid transport system accessory field, be used primarily in fuel system, oil system or other low-pressure fluid induction systems, be 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 use pipe made in Great Britain in a large number；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, and the conduit for low pressure pipeline imperial sizing uses threaded；Metric system pipe standards are external diameter × wall thickness, are generally used for seamless pipe, and connected mode typically uses welding.When using pipe made in Great Britain, in order to ensure that the reliable flexible between these conduits connects, need the connector that design is suitable for.
A kind of clamping hoop type flexible connector connected for pipeline as disclosed in prior art CN201120569784.1, it is provided with sleeve pipe, sealing ring is had on sleeve pipe, sleeve it is cased with outside sleeve pipe, sleeve is outside equipped with clip, clip is two semi-rings retractable structures by hinge-coupled, realizes fixing and release by latch hook.By clip compression sleeve, crush seal circle after sleeve deformation, sealing ring is made to produce the purpose that deformation reaches to be tightly connected, but the sleeve pipe of above-mentioned technology is to use integrated formed structure, by clip compressional deformation amount big time just can play the purpose being tightly connected, this just require sleeve pipe the size that material is elastic material or sleeve pipe must supporting, need customization use, and sleeve pipe once damages and is difficult to find succedaneum, this makes troubles just to installation and use.
Summary of the invention
The invention is intended to provide the flexible connecting member of a kind of general pipeline, higher to material and the dimensional requirement of sleeve pipe to solve the connector of prior art, 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, sleeve and hoop component, sleeve pipe is connected by mechanical stitch mode with conduit, described sleeve includes circular inner sleeve and two semicircular outer sleeves, one end of described sleeve pipe is provided with the female thread being connected with conduit, the other end is provided with seal groove, and described sealing ring is positioned at seal groove；Being matched in clearance between described sleeve pipe and inner sleeve, described inner sleeve external rings is provided with a plurality of extruding raised line, and described hoop component is positioned at the outside of outer sleeve and for tightly pluging with molten metal sleeve.
The operation principle of the present invention: use and from internal mechanical rolling depression method, two conduits and two sleeve pipes are securely attached together, sealing ring on overlapping respectively in the seal groove of two sleeve pipes having connected conduit, then one of these two sleeve pipes is inserted in from two of inner sleeve, then two outer sleeves are stuck in outside inner sleeve, finally hoop component is enclosed within outside outer sleeve, hoop component is tightened, hoop component extruding outer sleeve, outer sleeve produces the extruding raised line of elastic deformation extruding inner sleeve, inner sleeve is made also to produce elastic deformation and then crush seal circle, make sealing ring be extruded the certain decrement of generation by inner sleeve and play sealing function；Owing to having matched in clearance between sleeve pipe and inner sleeve, therefore conduit can tilt certain angle relative to inner sleeve thus reach the purpose flexibly connected.The setting by two outer sleeves of the flexible connecting member of the present invention, the i.e. setting of 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, also the effect being tightly connected can be reached, it is simple to find succedaneum to change without matching used sleeve；When hoop component is to sleeve extruding, sealing ring is produced radial compression amount by radial pressure and seals, and is produced axially and radially decrement relative to the rubber seal of domestic conventional catheter flexibility connector by axial compressive force and seals and be more prone to realization and seal；Sleeve pipe and conduit use mechanical stitch mode to link together from inside, and the reliability of connection is higher, construction weight is relatively light, is particularly suited for aerospace equipment.
Further, described hoop component includes that open annular clip, bolt and self-locking nut, the two ends of described open annular clip 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 purpose being tightly connected.
Further, described casing inner diameter is more than catheter outer diameter.The external diameter of all size imperial sizing conduit that the physical dimension aerospace equipment to be fully taken into account of sleeve pipe and the fuel system of other plant equipment, oil system and other fluid systems are commonly used and wall thickness, combine conduit maximum working pressure according to conduit size and determine sleeve pipe overall dimensions, the i.e. minimum limit of size of casing inner diameter is greater than the maximum limit of size of catheter outer diameter so that can successfully be enclosed within conduit, and by hydraulic pipe strength calculation formula, the sleeve pipe of each specification is carried out Strength co-mputation.
Further, described sleeve pipe is duralumin, hard alumin ium alloy sleeve pipe.When using mechanical stitch mode to link together with conduit from inside sleeve pipe, sleeve pipe can be by the tension force outside from inside, this just requires that sleeve pipe to have certain intensity, and aerospace equipment and operating pressure the least maximum only 0.25MPa within the fuel system of other plant equipment, oil system in general, typically select duralumin, hard alumin ium alloy for alleviating weight；Because not producing stress corrosion after requiring the material of pipe box to adapt with this material i.e. to contact, need duralumin, hard alumin ium alloy is carried out surface anodization process.
