Description
Technical field
The present invention relates to pipe fitting technical field, particularly insulating joint.
Background technology
Existing insulating joint includes upstream flange, downstream flange, sleeve pipe and dead ring mostly; its middle sleeve adopts the mode welded to fix with upstream flange or downstream flange; this single connected mode can make the crushing resistance that insulating joint is in use affected by external force can not get ensureing; and the implant between insulating joint and conduit is also without good protective measure; causing being highly susceptible in work process damaging, unreasonable in all structures causes that the service life of insulating joint is not ideal enough.
Summary of the invention
It is an object of the invention to provide a kind of solid and reliable, crushing resistance good and the insulating joint of high life.
The technical scheme realizing the object of the invention is as follows:
Insulating joint, including the upper flange welded with upstream conduit and the lower flange welded with downstream conduit, also include sleeve pipe and the dead ring clamped by upper flange and lower flange, described dead ring is set with rubber sleeve, described sleeve pipe axial cross section is Z-shaped, described sleeve pipe one end is connected with upper flange, insulation spacer and insulation fill stratum is from inside to outside set gradually between the sleeve pipe other end and downstream conduit, described upper flange outer wall is provided with external screw thread, described internal surface of sleeve pipe arranges the female thread with upper flange threaded engagement with upper flange corresponding section, described sleeve pipe welds with upper flange near the end of upper flange, described sleeve pipe does not contact with lower flange, cavity is formed between sleeve pipe and lower flange, described sleeve pipe is set with rubber protecting jacket near one end of lower flange.
Further, in order to improve the safety of insulating joint, in described cavity, lower flange is provided with discharge tip.
Preferably, in order to make the connection between sleeve pipe, downstream conduit and insulation fill stratum more tight, the side that described sleeve pipe and downstream conduit contact with insulation fill stratum is equipped with wave-shaped trench.
After adopting said structure; threaded with upper flange employing and welding the two ways of sleeve pipe is fixing to be connected; strengthen the firmness between sleeve pipe and upper flange; the rubber protecting jacket that one end that sleeve pipe contacts with insulation fill stratum is arranged protects insulation fill stratum well; invention increases the resistance to compression degree of insulating joint, improve the service life of insulating joint.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of the present invention.
In figure: 1 is upstream conduit, 2 is upper flange, and 3 is downstream conduit, and 4 is lower flange, and 5 is sleeve pipe, and 6 is dead ring, and 7 is rubber sleeve, and 8 is insulation spacer, and 9 is insulation fill stratum, and 10 is cavity, and 11 is rubber protecting jacket, and 12 is discharge tip.
Detailed description of the invention
nullInsulating joint of the present invention includes the upper flange 2 that welds with upstream conduit 1 as shown in Figure 1、The lower flange 4 welded with downstream conduit 3、Sleeve pipe 5 and the dead ring 6 clamped by upper flange 2 and lower flange 3，Described dead ring 6 is set with rubber sleeve 7，Described sleeve pipe 5 axial cross section is Z-shaped，Described sleeve pipe 5 one end is connected with upper flange 2，Insulation spacer 8 and insulation fill stratum 9 is from inside to outside set gradually between sleeve pipe 5 other end and downstream conduit 3，Described insulation fill stratum 9 is epoxide resin material，Described upper flange 2 outer wall is provided with external screw thread，Described sleeve pipe 5 inwall arranges the female thread with upper flange 2 threaded engagement with upper flange 2 corresponding section，Described sleeve pipe 5 welds with upper flange 2 near the end of upper flange 2，Described sleeve pipe 5 does not contact with lower flange 4，Cavity 10 is formed between sleeve pipe 5 and lower flange 4，In described cavity 10, lower flange 4 is provided with discharge tip 12，Described sleeve pipe 5 is set with rubber protecting jacket 11 near one end of lower flange 4，The side that described sleeve pipe 5 and downstream conduit 3 contact with insulation fill stratum 9 is equipped with wave-shaped trench.
When the present invention assembles; threaded with upper flange employing and welding the two ways of sleeve pipe is fixing to be connected; strengthen the firmness between sleeve pipe and upper flange; the rubber protecting jacket that one end that sleeve pipe contacts with insulation fill stratum is arranged protects insulation fill stratum well; the setting of discharge tip improves the safety of insulating joint; the connection that the wave-shaped trench of sleeve pipe and downstream conduit improves between insulation fill stratum and sleeve pipe and downstream conduit is tightr; invention increases the resistance to compression degree of insulating joint, improve the service life of insulating joint.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in the scope of patent protection of the present invention.
