Detailed Description
The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments, not all embodiments, of , and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 6, kinds of pipe connection devices comprise an outer pipe 1 and a connector, wherein an inner pipe 2 is arranged in the outer pipe 1, the inner pipe 2 is used for conveying liquid or gas, and the outer pipe 1 can be used as a protection pipeline to prevent the inner pipe 2 from directly leaking after being broken.
The connector comprises a connecting disc 3 and a quick joint, the quick joint comprises an outer pipe quick joint 4 communicated with the outer pipe 1 and an inner pipe quick joint 5 communicated with the inner pipe 2, the outer pipe quick joint 4 and the inner pipe quick joint 5 are respectively connected with the connecting disc 3 through threaded through holes 6, and the connecting disc 3 is connected with the outer pipe 1. The connection disc 3 and the outer tube 1 may be coupled by a screw thread.
When in use, the inner pipe 2 is connected with the inner pipe quick connector 5; then the connecting disc 3 is connected with the outer tube 1, and after the connecting disc 3 is connected with the outer tube 1, the inner tube 2 quick connector on the connecting disc 3 is communicated with the outer tube 1. Liquid or gas enters the inner pipe 2 through the inner pipe quick connector 5, and the quick connector of the outer pipe 1 can correspond to a high-pressure gas source or a leakage alarm. When the gas (natural gas, methanol gas) conveyed in the inner pipe 2 leaks, the gas cannot be directly discharged, but enters the outer pipe 1, and the alarm is triggered.
And , determining the number of the inner pipes 2 according to the number of pipelines to be conveyed, for example, when an oil inlet channel and an oil return channel are provided, two inner pipes 2 are provided, the inner pipes 2 correspond to the inner pipe quick joints 5 , that is, when two inner pipes 2 are provided, two inner pipe quick joints 5 are also provided, of course, the number of the connectors of the outer pipe 1 can also be set according to the actual situation, and two connectors are provided in the figure.
, the outer pipe quick connector 4 and the inner pipe quick connector 5 are preferably quick-plug connectors in the prior art, and are connected in a plug-in manner.
, a boss 7 is arranged on the connecting disc 3, an external thread can be arranged on the boss 7, and a corresponding internal thread is arranged on the inner surface of the outer tube 1.
The above description has been made in detail only for the preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art, and all such changes are intended to be encompassed by the present invention.
