Description

Pipeline installation connecting device Technical Field The utility model relates to the technical field of pipeline installation, in particular to a pipeline installation connecting device. Background When carrying out gas transportation or other gas transportation, need communicate a plurality of pipelines and carry, if carry the circuit of gas when longer, consequently need a plurality of pipeline connection extension to the whole length of pipeline has been increased. In the prior art, two pipelines are directly connected in a threaded manner, and the outer side of the pipeline is sealed through sealing rubber or sealing glue. The sealing mode has poor sealing effect, can easily cause air leakage of the pipeline, and can easily cause corrosion at the joint of the pipeline if corrosive gas is conveyed, thereby causing air leakage. Disclosure of utility model The utility model aims to provide a pipeline installation connecting device so as to achieve the purpose of preventing pipeline leakage. The technical scheme of the utility model is realized as follows: The utility model provides a pipeline installation connecting device, includes isolation section of thick bamboo and ring flange, the one end of isolation section of thick bamboo realizes being connected with the pipeline through cup jointing in the outside of pipeline butt joint end, the ring flange is through cup jointing in the outside other end of isolation section of thick bamboo realize being connected with the isolation section of thick bamboo, and butt joint between the ring flange of the pipeline tip of two butt joints for two pipelines, isolation section of thick bamboo intercommunication. In the pipe installation connection device as described above, preferably, the isolation cylinder includes a cylinder body, a limiting disc and a sealing portion, the limiting disc and the sealing portion are all annular and are respectively disposed at two ends of the cylinder body, the sealing portion is used for sleeving the pipe, the limiting disc is used for connecting the flange, and outer diameters of the sealing portion and the limiting disc are both larger than the outer diameter of the cylinder body. In the pipe installation connection device as described above, preferably, the flange plate includes an engagement groove and a connection plate, the engagement groove is annular, an outer ring diameter of the engagement groove is adapted to an outer ring diameter of the stopper plate, an inner ring diameter of the engagement groove is adapted to an outer ring diameter of the sealing portion, the connection plate is annular, and an inner ring of the connection plate is connected to an outside of a notch of the engagement groove. In one of the pipe installation connection devices described above, it is preferable that the depth of the fitting groove is greater than the thickness of the limiting plate. In one of the pipe installation connection devices described above, preferably, the limiting plate is detachably connected with the flange plate through bolts. In the above-described pipe fitting connection device, preferably, sealing rubbers are provided on both the inner wall surface of the orifice edge of the sealing portion and the inner wall surface of the notch edge of the fitting groove, and the sealing rubbers are used for sealing the joint between the inner wall surface of the sealing portion and the outer wall surface of the pipe and the flange plate, respectively. In one of the pipe installation connection devices described above, preferably, the inner wall surface of the sealing portion is provided with a screw thread that is adapted to the outer wall surface of the abutting end of the pipe, and the pipe is screwed between the sealing portions. The utility model has the following beneficial effects: Through installing the isolation tube additional at the tip of pipeline, utilize the mode that isolation tube and ring flange are connected for pipeline, isolation tube and ring flange constitute the intercommunication each other.
