Abstract

The utility model relates to a surperhigh pressure pipe clip, which aims to solve the technical problems in prior art that the pipe clip has a bad tensile strength and is easy to run out when the pressure is quite large in the pipe and the pipeline is easy to swing when the pipe clip is connected with the water injecting pipeline that is suspended over a long distance but is not supported. In order to solve the above technical problems, the utility model comprises a half round yoke buttoned at the pipe nozzle and is characterized in that: the yoke buckling surface is respectively provided with at least two convex platforms which can be cramped in the pipe nozzle groove. This structure greatly improves the tensile strength of the pipe strap and effectively prevents the ease of pipe strap falling off the groove when the pipe inside pressure is excessively large as well as increasing the bearing force of the pipe strap; in addition, the utility model has the advantages of simple structure and convenient installation, effective settlement of swing problem when filling water with the pipe, and safety improvement.

Description

The ultrahigh pressure pipe clamp

Technical field

The utility model relates to a kind of assembling pipe joint, specifically a kind of ultrahigh pressure pipe clamp.

Background technique

When tap water, gas fuel or heat supply pipeline are laid, all use various seal connectors that pipeline is coupled together in large quantities at present.The bearing capacity of pipeline and sealability mainly are subjected to the restriction of link, thereby the quality of link structure directly has influence on the laying quality of pipeline.

Now tube for fluid transfer road Connecting format has flange connection, welding, bayonet joint and pipe clamp to be connected etc.Wherein pipe clamp connect since its install fast, convenient, be widely used in the various pipe-line systems of water drainage-supply system, fire-fighting system, ship industry and mining industry with aspects such as pipe-line systems.Existing pipe clamp generally comprises and a pair ofly is fastened on the semicircle clip that needs mouth of pipe place, butt tube road and is arranged on the ring packing cushion rubber in the concave cavity in the middle of the clip, the clip two ends have a fixed-use bolt hole, be respectively equipped with a circle boss on the clip buckling surface that is interlocked with pipeline, this boss is stuck in the groove that needs mouth of pipe place, butt tube road.The pipe clamp of this kind structure is owing to have only a circle boss on its buckling surface, when the pipe internal pressure was excessive, pipe clamp was easily deviate from groove, has an accident.In addition, when existing pipe clamp did not have the filling pipe of support connecting long distance suspension, dancing can take place in pipeline, has had a strong impact on the Security of pipe coupling.

Summary of the invention

The purpose of this utility model be poor for the resistance to tension that solves the pipe clamp that prior art exists, when the pipe internal pressure is excessive pipe clamp easily deviate from and pipe clamp connecting that long distance hangs when not have the filling pipe of support, technical problems such as dancing can take place in pipeline, and a kind of resistance to tension that provides is strong, bearing capacity is high, prevent the ultrahigh pressure pipe clamp that filling pipe is swung.

In order to solve the problems of the technologies described above, the utility model ultrahigh pressure pipe clamp comprises a pair of semicircle clip that is fastened on pipeline mouth of pipe place, it is characterized in that: be respectively equipped with at least two circles on the described clip buckling surface and may be stuck in the interior boss of pipeline mouth of pipe place groove.

In order to reach better sealing effect, in the further detailed structure of the utility model, also have following technical characteristics: described pipe clamp comprises that also one is arranged on the O-ring seal in the middle concave cavity of clip, and the centre of sealing cushion rubber is provided with the outstanding annular seal lip limit of a circle.

In order to make the pipe clamp stress equalization, in the further detailed structure of the utility model, also has following technical characteristics: be respectively equipped with two circle boss on the described clip buckling surface.

In order to make pipe clamp have better resistance to tension, in the further detailed structure of the utility model, also have following technical characteristics: a circle boss wherein is arranged on the outermost of clip buckling surface.

For pipe clamp can be clamped on the pipeline more firmly, in the further detailed structure of the utility model, also have following technical characteristics: described clip two ends are respectively equipped with two bolts hole.

The utlity model has following advantage and good effect: because the utility model adopted said structure, improved the resistance to tension of pipe clamp greatly, pipe clamp is easily deviate from groove when having prevented effectively that the pipe internal pressure is excessive, has increased the bearing capacity of pipe clamp; In addition, simple in structure, easy for installation, the vibration problems when also having solved the pipe water filling effectively of the utility model has improved Security.

Embodiment

Referring to Fig. 1-Fig. 6, the utility model ultrahigh pressure pipe clamp comprises and a pair ofly is fastened on the semicircle clip 10 at pipeline 30 mouth of pipe places and is arranged on the O-ring seal 20 in the concave cavities 14 in the middle of the clip 10, the centre of sealing cushion rubber 20 be provided with a circle outstanding with annular seal lip limit 21 its one.Clip 10 two ends are respectively equipped with two fixed-use bolt holes 12, are respectively equipped with two on clip 10 buckling surfaces and enclose the boss 11 that may be stuck in pipeline 30 mouth of pipe place grooves 31, and a circle boss 11 wherein is arranged on the outermost of clip 10 buckling surfaces.

When using the utility model pipe clamp, once roll out two circle grooves 31 at pipeline 30 two ends by channeling machine earlier, earlier O-ring seal 20 is contained in an end of a pipe, be close to an end of another root pipe and align, hydrodynamic reciprocating sealing cushion rubber 20 is to two tubes, boss 11 with clip 10 is stuck in the groove 31 of pipeline 30 again, and O-ring seal 20 embeds in the clip 10 simultaneously, and the bolton of being screwed in clip 10 two ends at last gets final product.

Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
