Abstract
The invention relates to an insulation joint. The insulation joint comprises an upper flange in welding connection with an upstream conduit, a lower flange in welding connection with a downstream conduit, a casing pipe and an insulation ring clamped by the upper flange and the lower flange; the insulation ring is sleeved with a rubber sleeve, the axial cross-section of the casing pipe is in a Z shape, one end of the casing pipe is connected with the upper flange, an insulation spacer and an insulation filling layer are arranged between the other end of the casing pipe and the downstream conduit in sequence from inside to outside, the outer wall of the upper flange is provided with outer threads, the position, corresponding to the upper flange, of the inner wall of the casing pipe is provided with inner threads matched with the threads of the upper flange, the end, near to the upper flange, of the casing pipe is in welding connection with the upper flange, the casing pipe makes no contact with the lower flange, a cavity is formed between the casing pipe and the lower flange, and the end, near to the lower flange, of the casing pipe is sleeved with a rubber protective sleeve. According to the insulation joint, the pressure resistance degree of the insulation joint is increased, and the service life of the insulation joint is prolonged.
Description
Technical field
The present invention relates to pipe fittings technical field, particularly insulating joint.
Background technique
Existing insulating joint comprises upstream flange, downstream flange, sleeve pipe and dead ring mostly; its middle sleeve adopts the mode of welding to fix with upstream flange or downstream flange; the crushing resistance that this single Placement can make insulating joint in use affect by external force can not get ensureing; and the packing between insulating joint and conduit does not have good protective measure yet; cause being easy in working procedure be damaged, allly structurally unreasonablely cause the working life of insulating joint not ideal enough.
Summary of the invention
The object of this invention is to provide a kind of solid and reliable, crushing resistance good and the insulating joint of high life.
The technological scheme realizing the object of the invention is as follows:
Insulating joint, comprise the upper flange welded with upstream conduit and the lower flange welded with downstream conduit, the dead ring also comprising sleeve pipe and 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 the other end and downstream conduit, described upper flange outer wall is provided with outside thread, described internal surface of sleeve pipe and upper flange corresponding section arrange the internal thread with upper flange screw-thread fit, 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 Security 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; sleeve pipe and upper flange adopt the two kinds of modes be threaded with welding to be fixedly connected with; 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 working 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 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.
Embodiment
Insulating joint of the present invention comprises the upper flange 2 welded 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 the other end and downstream conduit 3, described insulation fill stratum 9 is epoxide resin material, described upper flange 2 outer wall is provided with outside thread, described sleeve pipe 5 inwall and upper flange 2 corresponding section arrange the internal thread with upper flange 2 screw-thread fit, 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; sleeve pipe and upper flange adopt the two kinds of modes be threaded with welding to be fixedly connected with; 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 Security 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 working 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 utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
