Abstract
The utility model relates to a pipeline structure which is a pipeline joint structure concretely. The pipeline joint structure consists of a pipeline of equal section, a clasp is sleeved at the periphery of the end of the pipeline, and the clasp is welded and fixed at the end of the pipeline. The utility model can be used for large diameter pipeline, with good reliability of connection and no effect on the pipeline inner diameter.
Description
Technical field
The utility model relates to the structure of pipeline, specifically is a kind of pipe joint structure.
Background technique
Existing be used for fields such as chemical industry, coal gas, electric power, metallurgy, mine, shipbuilding large-size pipe, its joint structure generally as shown in Figure 1, promptly process an annular groove A near the mode by roll extrusion on the outer wall of connecting end, then two segment pipes are connected by clip at pipeline.The joint structure of this structure because the slot rolling root has circular arc, can not combine with hoop tube adaptor is complete on the one hand, influences join strength, may be because of the poorly sealed phenomenon that leaks that produces; Because the internal diameter at pipeline process roll extrusion slot rolling position diminishes, the throttling phenomenon is arranged on the other hand, cause the pressure loss of pipeline inner fluid.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of pipe joint structure that large-diameter pipeline, connection reliability are good, do not influence internal diameter of the pipeline that can be used in is provided.
Pipe joint structure of the present utility model comprises a prismatic pipeline, is with a snap ring in the periphery, end of pipeline, and snap ring is weldingly fixed on the end of pipeline.
The utility model is owing to adopt the structure of external snap ring, and snap ring and clip by two segment pipes cooperate realizes that pipeline is connected, thereby internal diameter of the pipeline is not had influence, has avoided the pressure loss of pipeline inner fluid; Can protrude in pipeline outer wall owing to snap ring in addition morely, thus more firm with cooperating of clip, improved the reliability that pipeline connects.
Description of drawings
Fig. 1 is traditional pipe joint structure schematic representation;
Fig. 2 is a pipe joint structure schematic representation of the present utility model;
Fig. 3 is the structural representation of the utility model under the as installed state;
Fig. 4 is the end view of clip installment state.
Embodiment
As shown in Figure 2, pipe joint structure of the present utility model is to be fixed with a snap ring 2 in the end of pipeline 1 peripheral solder.
As shown in Figure 3, Figure 4, when two segment pipes 1 connect, its end butt joint, two snap rings 2 are fixedly connected by the end to end clip of plurality of sections 3.
Claims (1)
1, a kind of pipe joint structure is characterized in that: it comprises a prismatic pipeline (1), is with a snap ring (2) in the periphery, end of pipeline, and snap ring is weldingly fixed on the end of pipeline.
