Description
Technical Field
The utility model relates to a connecting device of pipeline, specifically speaking indicate the flange formula connecting device of compound pipe.
Background
In the prior art, a plurality of sections of composite pipes are connected into a complete pipeline in a flange fixed connection mode. The flange connection mode requires that the end parts of the composite pipes are fixedly provided with force applying components (namely, connecting rings in the technology), and the force applying components at the end parts of the two composite pipes are clamped when the flanges are locked so as to achieve the pipeline connection effect. Because a construction site is rarely provided with complete auxiliary welding equipment, the end parts of the existing composite pipes are fixedly welded with force-applying parts before delivery. The force-applying component is clamped between the flanges, so the outer diameter of the force-applying component is necessarily larger than that of the composite pipe, namely, the two ends of the composite pipe are in a protruding structure, and the flanges are required to be assembled on the composite pipe before the force-applying component is arranged. The composite pipes are in a stacked state in transportation or storage, the contact surface of two adjacent composite pipes is mostly only the circumferential surface of the force application part or the circumferential surface of the flange, and the circumferential surface area of the force application part or the circumferential surface area of the flange is small, but the weight of the composite pipe is large, so that the pressure intensity of the joint of the two adjacent composite pipes is too high, the outer surface of the composite pipe is crushed, the force application part is pressed and deformed, and the like. Particularly, in the transportation process, the damage degree of the composite pipe and the force application part is heavier due to the jolt of the road surface, so that the service life of the composite pipe and the sealing precision between the pipeline connections are greatly influenced, and further, the defects of high maintenance cost, poor use effect and the like are caused.
Disclosure of Invention
The utility model provides a flange formula connecting device of compound pipe to the pipeline surface of overcoming current compound union coupling structure existence is damaged, sealed effect receives the influence scheduling problem between the pipeline by the pressure easily when transportation or storage.
The utility model adopts the following technical scheme:
the flange connecting device of the composite pipe comprises at least two flanges and a sealing element, wherein the sealing element is assembled on the connecting end surfaces of the two composite pipes, and the sealing element is a sealing ring or an annular sealing gasket. The composite pipe connecting end is provided with a mounting groove, the groove wall of the mounting groove adjacent to the sealing element is a near groove wall, the groove wall departing from the sealing element is a far groove wall, and the height of the near groove wall is smaller than or equal to that of the far groove wall. The mounting groove is provided with a connecting piece in a matching mode, the connecting piece is buckled on the top edge of the near groove wall, the side wall of the flange is connected with the connecting piece in a pressing mode, and the two composite pipes are connected in a locking mode through the flange.
More specifically:
the connecting piece is in a semicircular ring shape, the cross section of the connecting piece can be in a 7 shape, and the cross section of the connecting piece can also be in a T shape. The end part of each composite pipe is preferably provided with two connecting pieces which are spliced into a circular ring structure.
