The utility model discloses a gas quick connecting pipe for solve gas pipe network and branch road of branch family, because of the pipeline breaks or connects new pipeline in addition for branch road user's etc. needs, and the pipeline maintenance or the change of going on. As shown in fig. 2, the old pipeline 5 is used to represent the cut gas pipeline, and in the existing construction process, the new pipeline to be installed and the old pipeline 5 are welded or screwed on site, so that the operation time is required to be long, and the gas stopping time can be prolonged; meanwhile, because the time requirement is tight and limited by installation conditions and environment, the quality of installation of new and old pipelines can not be guaranteed easily.
Especially, the branch lines of each household are mostly laid along the wall, limited by narrow space and the like, and generally do not have welding or tapping operation conditions, so that the construction difficulty is greatly improved. When the gas pipeline connecting device is used for connecting new and old gas pipelines, the new and old gas pipelines can be quickly connected and installed without welding or tapping operation, so that the construction efficiency and quality are improved, and the operation and the use are convenient.
As shown in fig. 1 and 2, the gas quick-connecting pipe includes a first connecting pipe 1 and a second connecting pipe 3. During the use, accomplish the gas pipeline cutting at former leakage position after, through first installation pipe fitting 2 and/or second installation pipe fitting 4 with first connecting pipe 1 or 3 way of second connecting pipe with the incision tip of old pipeline 5 be connected. Therefore, the installation efficiency and quality can be better improved, and the construction period and the air stopping time are shortened.
As shown in fig. 3, the first mounting pipe members 2 are provided at both ends of the first connection pipe 1, respectively, in this embodiment. The first mounting tube 2 comprises an elastic sealing sleeve 21, a sealing gasket 22 and a movable joint. The movable connector is matched with the end part of the first connecting pipe 1 by adopting a threaded structure, and the sealing gasket 22 and the elastic sealing sleeve 21 are compressed to realize the sealing connection of the first connecting pipe 1 and a pipeline to be connected.
The movable connector comprises an end cover 23 and a connecting cylinder 24 arranged on one side of the end cover 23, the sealing gasket 22 is arranged between the end cover 23 and the elastic sealing sleeve 21, the sealing gasket 22 and the end cover 23 are provided with middle through holes matched with a pipeline to be connected. The pipe to be connected is the cut end of the old pipe.
The connecting cylinder 24 is matched with the end part of the first connecting pipe 1 by adopting a threaded structure, and the end cover 23 is utilized to compress the sealing gasket 22 and the elastic sealing sleeve 21 to realize the sealing connection of the first connecting pipe 1 and a pipeline to be connected.
As shown in fig. 1, in order to increase the length of the pipe, a second connection pipe 3 is provided at one end of the first connection pipe 1. The second connecting pipe 3 comprises a second mounting pipe fitting 4, a thick connecting pipe 32 and a thin connecting pipe 31, wherein the thick connecting pipe 32 is fixedly and hermetically connected with one end of the thin connecting pipe 31, the second mounting pipe fitting 4 is mounted at the other end of the thick connecting pipe 32, and the other end of the thin connecting pipe 31 is hermetically connected with the first connecting pipe 1 through a first mounting pipe fitting 2.
With continued reference to fig. 1, the first mounting tube 2 and the second mounting tube 4 are identical in construction in this embodiment. Two sets of second connecting pipes 3 are arranged and are respectively arranged at two ends of the first connecting pipe 1.
In this embodiment, the first connecting pipe 1, the second connecting pipe 3 and the movable connector are made of metal materials. The first connecting pipe 1 and the second connecting pipe 3 can be prefabricated and then assembled for use. The elastic sealing sleeve 21 and the sealing gasket 22 are made of rubber materials, and gaps between new and old pipelines are sealed by utilizing the good sealing effect of the elastic sealing sleeve 21 so as to ensure that no leakage exists during gas transmission and use; at the same time, the sealing gasket 22 and the end cover 23 exert pressure to position and fix the elastic sealing sleeve 21.
