Description

Loose joint for pipe installation

The connection that the utility model relates between the plumbing pipe is installed and the loading and unloading maintenance.

Original union is the big nut of spill inner stopper by an end, its two ends connect an end respectively and are the primary nut of convex outer stopper and the primary nut of screw assembling, its objective is and connect two pipelines, but owing to 0～5 millimeter in the gap between the primary nut of two correspondences, so piping erection and maintenance are just had very big difficulty, in actual piping erection, maintenance, to take a lot of work, require great effort, middle rubber pad is fragile again.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provides a kind of new pipe to the silk union, thereby more accurate, carry out the installation and the maintenance of pipeline more easily.

Technical solution of the present utility model is: have on the length fiber tube 4 of set screw nut moving nut 3 of assembling and harness cord pipe collar 2.

Accompanying drawing of the present utility model is the sectional view after connecting between the pipeline.

Below in conjunction with accompanying drawing the utility model embodiment is further described: set screw nut of welding on length fiber tube 4, the perhaps direct whole length fiber tube 4 of machining, moving nut 3 and harness cord pipe collar 2 are assemblied in the long filament end of length fiber tube 4 successively, the working principle of its whole erection is: existing short silk end with length fiber tube 4 directly is assemblied on a certain steam pipe fitting 5, again nut 3 and harness cord pipe collar 2 are assembled at the end on length fiber tube 4 temporarily, the long filament end of length fiber tube 4 is to the neat size of next joint connecting tube one end, be to connect by neat size connecting tube 1, instantly after next saves connecting tube and neat size connecting tube 1 is connected, the long filament end of its connecting tube 1 end and length fiber tube 4 has certain distance, " the pipe; then its open distance is 10～15 millimeters; harness cord pipe collar 2 is withdrawed from connecting tube 1 be connected then; after screwing moving nut 3, the connection of whole pipe finishes that as adopts 1/2.In like manner in maintenance, need to change two ends connecting tube 1 or 5, then unload pipe successively silk union and connecting tube are got final product.

The utility model has the advantages that:

Install very conveniently, and accurately reliable, be applicable to the zinc-plated pipeline of steam of various bores, material is saved in installation and the maintenance in steam black pipe road, and the easy processing and fabricating of the utility model.

Claims (1)

1, a kind of pipe comprises nut 3 to the silk union, it is characterized in that: have on the length fiber tube 4 of set screw nut moving nut 3 of assembling and harness cord pipe collar 2.
