Abstract
The utility model aims to provide an expansion joint type flange which is used for connection of pipelines provided with thin pipe walls. The technical scheme includes that the expansion joint type flange comprises a flange body, and at least one groove is installed on the lower portion of the flange body. The expansion joint type flange is simple in structure, can be fast and effectively connected with the pipelines, cannot damage the pipe walls, and has good fastening effect on the pipe walls.
Description
Technical field:
The utility model relates to flange, particularly a kind of expansion-fit flange.
Background technique:
The flange that is used for now connecting tube, generally be divided into clip connected, be threaded, weld this several Placements, above-mentioned several flanges, shortcoming is more, user cost is higher, installation procedure is comparatively complicated, and especially when the pipe wall that needs to connect was thinner, the strength of tube wall was limited, the flange of above-mentioned these several Placements all is not suitable for using, design is a kind of to be applicable to the thinner flange of connected tube tube wall with regard to needing, though the applicant has solved the problems referred to above at the patent ZL 201020219636.2 of first to file, but still exists partly not enough.
Summary of the invention:
The purpose of this utility model is a kind of expansion-fit flange that is applicable to connect the thinner pipeline of tube wall of design.
The technical solution of the utility model is, a kind of expansion-fit flange, and it comprises flange body, it is characterized in that: be provided with at least one groove in the flange body bottom.
The utility model is simple in structure, and connecting tube can not damage tube wall fast and effectively, and better to the fastening effect of tube wall.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Describe by reference to the accompanying drawings embodiment in detail, specific embodiments of the present utility model is, a kind of expansion-fit flange, it comprises flange body 1, be provided with lead angle 5 between the inflation port 4 of flange body and straight hole 6, expansion loop 3 and seal ring 2 are installed in inflation port, seal ring also can substitute with O shape circle, be provided with at least one groove 7 in the flange body bottom, can effectively improve the fastening effect of tube wall.When using the utility model, pipeline is inserted between expansion loop and the seal ring, re-use expander, expansion loop is expanded, the expansion loop stress deformation with tube wall and sealed ring deformation, has played and will manage the effect that is tightly connected.The utility model is simple in structure, and is easy to install.
