Abstract
The utility model relates to a weld-free quick-connecting flange plate which is a couple of ring-shaped circular discs whose centers are provided with pipe punching holes and outer edges are provided with connecting holes and connecting bolts. The middle part of each ring-shaped circular disc is protruded with a round table shape towards one surface; the center of the round table is the pipe punching hole, and the hole wall of the center of the round table is provided with a ring-shaped sealed slot; the side surface of the round table is provided with positioning holes and positioning screws. The utility model has the advantages of easy fabrication, repeatable use after the disassembly and simple, convenient and quick installation, and the utility model does not need to be welded; a coating of a pipeline provided with the coating can not be damaged, and the service life of the pipeline can be extended; the engineering cost is reduced, and the fire hazard and the burning accident which are caused by the high temperature of the welding can be prevented; the utility model is an ideal product for the connection of low-temperature and low-pressure pipelines.
Description
The utility model relates to the flange plate that a kind of pipeline connects usefulness.
At present, it is the principal mode that pipeline connects that flange connects, and flange plate need be welded on the pipeline, realizes tube and tube, and pipe is connected with valve.Because welding needs with special equipment, special personnel operate, and just connection causes the situation that efficient is low, cost is high to pipeline for this.
The purpose of this utility model provides a kind of quick mounting flange of exempting to weld, and does not need welding machine, welding rod and welder to get final product quick mounting, reduces engineering cost.
Thisly exempt to weld quick mounting flange, be that a pair of center has pipe perforation, outer rim has the annular disc of attachment hole and connecting bolt, it is characterized in that: the middle part of annular disc is round table-like outstanding to one side, the round platform center is a pipe perforation, the annular seal groove is arranged on the hole wall at round platform center, and there are positioning hole and positioning screwn in the side of round platform.
The head center of above-mentioned positioning screwn is recessed, and the outer ring is outstanding.
The utility model when mounted, two flange plate are enclosed within on the pipeline, again seal ring set on pipe, and insert in the annular seal groove on the flange plate central tube perforation inwall, orifice plane is consistent with seal ring, then the connecting bolt of flange plate outer rim is tightened, at last the set screw of frustum cone side is tightened, allow set screw head outer ring be pressed into tube wall, prevent to move axially, reach and compress the purpose that seal ring is embraced tube wall.
The utility model has the advantages that easy to manufacturely, dismounting back is reusable; Install simple and convenient fast, need not weld, coated pipeline is not destroyed coating, prolong the pipeline life-span; Reduce engineering cost; Preventing to weld the fire of high temperature generation and the generation of burning accident, is the ideal product that low temperature, low pressure line connect.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is structure of the present utility model and scheme of installation.
As shown in the figure, thisly exempt to weld quick mounting flange, be that a pair of center has pipe perforation, outer rim that the annular disc 2,6 of four attachment holes and connecting bolt 1 is arranged, the middle part of annular disc is round table-like outstanding to one side, round platform 5,9 centers are pipe perforations, annular seal groove 8 is arranged on the hole wall at round platform center, interior edge annular seal bar 4, there are four corresponding positioning holes and positioning screwn 3,7 in the side of round platform.The head center of positioning screwn is recessed, and the outer ring tightly is stuck on the pipeline.
