Description

A kind of novel pressure pipe joint

Technical field

The utility model belongs to pressure pipeline technical field, especially relates to a kind of novel pressure pipe joint.

Background technique

Pressure pipeline refers to the pipeline of all receiving internal pressures or external pressure, manages interior medium regardless of it.Pressure pipeline is pipe A part in road, pipeline are flowed to convey, distribute, mix, separate, discharge, measure, control and prevent fluid, by Pipe, flange, is bolted pipe fitting, gasket, valve, other component parts or pressure-containing parts and set of bearings at assembly.

In order to increase the length of pipeline, the welding between pipeline is essential.The pressure pipeline of high length is by more Shorter pressure piping is formed by connecting between two pressure pipings to be attached by connection types such as welding, existing pressure pipe There is no any safeguard measure at the solder design in road, exposes in air, after pressure pipeline is worked long hours, pressure pipe Easily corroded by foreign object at the solder design in road.Pressure pipeline after corrosion can leak during the work time, not only result in The waste of raw material, or even will affect the safety in production of enterprise, it is therefore necessary to it is improved.

Summary of the invention

The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of novel pressure pipeline and connect Head, there is exposure at the solder design for avoiding pressure pipeline to cause to aoxidize in air or corrode, the spy to prolong the service life for it Point.

To achieve the goals above, the technical scheme adopted by the utility model is a kind of novel pressure pipe joint, packet Include pressure tube body and joint body, the joint body includes integrally formed connecting tube and dirt-proof boot, the connecting tube Internal diameter be equal to pressure tube body outer diameter, the dirt-proof boot be it is horn-like, internal diameter of the dirt-proof boot far from connecting tube one end is big In dirt-proof boot close to the internal diameter of connecting tube one end, the dirt-proof boot is equipped with diversion trench, is additionally provided with sealing ring on the dirt-proof boot Slot.

Further, the connecting tube includes the first body, the second body and third body, and first body and third body are far from the One end of two-body is equipped with seal groove, is additionally provided with discontinuous screwed pipe on first body and third body.

Further, second body is screwed pipe.

Further, the connecting tube is externally provided with reinforcing rib.

Further, the connecting tube includes exposed surface layer, outer thermal insulation layer, intermediate enhancement layer, inner insulating layer and interior protection Layer, the intermediate enhancement layer are formed by warp and weft weaving, and the warp and weft use wire, the exposed face Layer and inner protective layer are that anti-corrosion material is constituted.

Further, the inner protective layer is coated with hydrophobic coating far from the side of inner insulating layer.

After adopting the above structure, the utility model is compared to the prior art advantageously: the connector sheet of the application Body includes integrally formed connecting tube and dirt-proof boot, and connecting pipe box are located at outside pressure tube body when in use, then in connecting tube Connecting tube and pressure tube body are welded by scolding tin with the junction of dirt-proof boot, dirt-proof boot is far from connecting tube one end at this time Internal diameter be greater than internal diameter of the dirt-proof boot close to connecting tube one end and can go on smoothly welding in this way, while dirt-proof boot can carry out weld seam It blocks and avoids weld seam from being directly exposed to air delaying to aoxidize, prolong the service life；Closure gasket groove is additionally provided on dirt-proof boot in this way After the completion of welding, card sets sealing ring in closure gasket groove, can preferably protect in this way to weld seam；Also set on dirt-proof boot There is diversion trench, in this way when there is liquid accidentally to splash dirt-proof boot inner wall, liquid runs down diversion trench is wandered about as a refugee dirt-proof boot, in this way can be into One step avoids outside liquid and bead contact that weld seam is caused to be corroded prolonging the service life.

Fig. 3 is the cross-sectional view of the utility model connecting tube.

Specific embodiment

As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model It encloses, the present invention will be further described with reference to the accompanying drawings and examples.

Embodiment, as shown in Fig. 1 to Fig. 3: a kind of novel pressure pipe joint, including pressure tube body 10 and connector sheet Body, it is characterised in that: wherein joint body includes integrally formed connecting tube 30 and dirt-proof boot 20, wherein the internal diameter of connecting tube 30 Equal to the outer diameter of pressure tube body 10, such connecting tube 30 be set in pressure tube body 10 it is outer when connecting tube 30 and pressure tube body Connection gap on 10 is small as far as possible, and wherein dirt-proof boot 20 is horn-like, and wherein dirt-proof boot 20 is far from 30 one end of connecting tube Internal diameter is greater than dirt-proof boot 20 close to the internal diameter of 30 one end of connecting tube, passes through weldering in the junction of connecting tube 30 and dirt-proof boot 20 in this way When tin is welded connecting tube 30 and pressure tube body 10, there are enough spaces that can go on smoothly welding, while dirt-proof boot 20 Weld seam can block and avoid weld seam from being directly exposed to air delaying to aoxidize, prolong the service life.It is also set on dirt-proof boot 20 There is closure gasket groove 43, in this way after the completion of welding, card sets sealing ring in closure gasket groove 43, can preferably carry out in this way to weld seam Protection；Diversion trench 50 is equipped on dirt-proof boot 20, in this way when there is liquid accidentally to splash 20 inner wall of dirt-proof boot, liquid runs down is led Chute 50 is wandered about as a refugee dirt-proof boot 20, can further avoid outside liquid in this way and bead contact causes the weld seam extension that is corroded to use the longevity Life.

Further, connecting tube 30 includes the first body 31, the second body 32 and third body 33, wherein the first body 31 and third body 33 one end far from the second body 32 are equipped with seal groove 42, and being equipped with the second sealing ring on seal groove 42 in this way can the company of further reducing Connection gap between adapter tube 30 and pressure tube body 10 avoids the medium in pressure tube body 10 from causing weld seam to bead contact Corrosion, prolongs the service life；It wherein is additionally provided with discontinuous screwed pipe 42 on the first body 31 and third body 33, works as pressure pipe in this way When medium in ontology 10 is liquid, barrier effect can be played to it, avoid contacting with the second sealing ring and cause the second sealing ring rotten Erosion is last and bead contact causes weld corrosion to prolong the service life.

Further, the second body 32 is screwed pipe, in this way convenient for the connection direction for changing pressure tube body 10, the scope of application It is wider.

Further, connecting tube 30 is externally provided with reinforcing rib 60, can improve the bonding strength of connecting tube 30 in this way, extends and uses Service life.

Further, connecting tube 30 includes exposed surface layer 71, outer thermal insulation layer 72, intermediate enhancement layer 73,74 and of inner insulating layer Inner protective layer 75, wherein intermediate enhancement layer 73 is formed by warp and weft weaving, wherein warp and weft use wire It is more pressure-resistant that intensity can be improved in this way, prolonged the service life；Wherein exposed surface layer 71 and inner protective layer 75 are anti-corrosion material structure At corrosion rate capable of being delayed to prolong the service life in this way.

Further, inner protective layer 75 is coated with hydrophobic coating far from the side of inner insulating layer, is avoided that works as pressure pipe in this way When intrinsic medium is liquid, liquid remains in joint body.

Pressure pipeline is widely used at present, and other structures and principle are same as the prior art, and which is not described herein again.
