the utility model provides a corrugated expansion joint with leak hunting structure, includes pipeline and corrugated expansion joint, and corrugated expansion joint includes the compensator pipeline, the compensator pipeline is the cylinder shape, and inside is the cavity state, and this compensator pipeline outside is provided with extends the shell, the welding of compensator pipeline one end has compensator ring flange one, and the welding of this compensator pipeline other end has compensator ring flange two, pipeline includes the pipeline, and this pipeline is close to corrugated expansion joint's one end welding has the pipeline ring flange, the two outsides of compensator ring flange are equipped with leak hunting protecting crust one and leak hunting protecting crust two.

Preferably, the diameters of the pipeline flange plate and the compensator flange plate are the same, and a plurality of threaded holes are formed in the pipeline flange plate and the compensator flange plate.

Preferably, the first leakage detection protective shell is semicircular, connecting blocks are welded at two ends of the first leakage detection protective shell, the connecting blocks are cuboid-shaped, and two threaded holes are formed in each connecting block.

Preferably, the first leakage detection protective shell and the second leakage detection protective shell have the same structure.

Preferably, the width of the inner side space of the first leakage detection protective shell and the second leakage detection protective shell is larger than the width of the pipeline flange and the compensator flange when the pipeline flange and the compensator flange are connected together.

Compared with the prior art, the utility model discloses following beneficial effect has: when using, dock and utilize the bolt fastening pipeline ring flange and compensator ring flange two, then the protecting crust that leaks with the inspection first not only can protect the ring flange not receive external environment's interference, can also play the effect that the inspection ring flange junction was revealed, the protecting crust that leaks with the inspection second material of protecting crust be transparent plastic, can resist influences such as high temperature, corruption, when the gap emergence leakage between pipeline ring flange and compensator ring flange two simultaneously, the liquid or the gas that spill over can be gathered by the protecting crust that leaks with the inspection second protecting crust because it is transparent material, so can be clear see the inside condition of the protecting crust that leaks with the inspection second protecting crust.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-3, a corrugated pipe compensator with a leakage checking structure comprises a conveying pipeline and a corrugated pipe compensator, the corrugated pipe compensator comprises a compensator pipeline 8, the compensator pipeline 8 is cylindrical and is hollow inside, an extension shell 2 is arranged on the outer side of the compensator pipeline 8, a compensator flange plate 1 is welded at one end of the compensator pipeline 8, a compensator flange plate 7 is welded at the other end of the compensator pipeline 8, the conveying pipeline comprises a pipeline 6, a pipeline flange plate 5 is welded at one end of the pipeline 6 close to the corrugated pipe compensator, and a leakage checking protective shell 3 and a leakage checking protective shell 4 are arranged on the outer side of the compensator flange plate 7; the diameter of the pipeline flange plate 5 is the same as that of the compensator flange plate II 7, and a plurality of threaded holes are formed in the pipeline flange plate and the compensator flange plate II; the first leakage detection protective shell 3 is in a semicircular ring shape, connecting blocks are welded at two ends of the first leakage detection protective shell, the two connecting blocks are in a cuboid shape, and two threaded holes are formed in each connecting block; the leakage detection protective shell I3 and the leakage detection protective shell II 4 are identical in structure; the width of the inner side space of the first leakage detection protective shell 3 and the second leakage detection protective shell 4 is larger than that of the pipeline flange 5 and the compensator flange 7 when the pipeline flange 5 and the compensator flange are connected together.

When the pipeline leakage detection device is used, the pipeline flange 5 is in butt joint with the compensator flange II 7 and is fixed through bolts, and then the first leakage detection protective shell 3 and the second leakage detection protective shell 4 are sleeved on the outer sides of the pipeline flange 5 and the compensator flange II 7.
