Abstract
The utility model relates to a pipeline flange which comprises a flange body provided with an inner hole. Positions tightly adhering to the inner edge of the flange body are axially provided with multiple arc insertion grooves in a protruding and extending mode, and reinforcing ribs are arranged between the insertion grooves and the flange body. According to the pipeline structure with the structure, pipelines are inserted through the insertion grooves, the connection stability between the flange and the pipelines in welding is enhanced, placement of the pipelines and the flange in welding by welders is facilitated, labor intensity is relieved, meanwhile, the structural strength after the pipelines are welded to the flange is high, and service life is prolonged.
Description
Technical field
The utility model relates to a kind of piping flange.
Background technique
The flange arrangement being connected with pipeline in prior art, direct two ends at pipeline by flange welding normally, but flange with before pipeline welding be connected and insecure, difficulty is shaped, conventionally flange need to be lain on worktable, again pipeline is vertically placed on flange body, thus the stability while strengthening welding.Yet there is certain defect in this mode, increased on the one hand welder's labor intensity, the welding posture that welder need to overlook to bow completes welding, not only increased welding difficulty, long bad welding posture simultaneously, has all caused certain infringement to welder's cervical vertebra etc.; On the other hand, because the joint area of contact of flange and pipeline is less, often also there is the defects such as the rear structural strength of welding is lower, working life is shorter.
Model utility content
The purpose of this utility model is to overcome the problem of above-mentioned prior art, a kind of piping flange is provided, its can strengthen when welding flange with pipeline between the stability that is connected, while facilitating pipeline and flange welding, welder's puts, reduce labor intensity, structural strength after pipeline and flange welding is higher simultaneously, increases the service life.
The purpose of this utility model is to be achieved through the following technical solutions: a kind of piping flange, comprise the flange body of orate, and described flange body is close to the slot that inner edge axially protrudes out a plurality of circular arcs, between described slot and described flange body, is provided with stiffening rib.
Further, the width of rebate of described slot and the thickness of pipeline equate.
Further, described slot and described flange body are integral type structure.
Further, described flange body has at least three slots, and described slot is distributed on described flange body.
Further, described flange body has six slots.
Further, described flange body is equipped with mounting hole.
A kind of pipeline configuration described in the utility model, a kind of piping flange, comprises the flange body of orate, described flange body is close to the slot that inner edge axially protrudes out a plurality of circular arcs, between described slot and described flange body, is provided with stiffening rib.The pipeline configuration of this structure, by slot plug-in mounting pipeline, the stability being connected between flange and pipeline while having strengthened welding, while having facilitated pipeline and flange welding, welder's puts, reduced labor intensity, the structural strength after pipeline and flange welding is higher simultaneously, has extended working life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of piping flange described in the utility model;
Fig. 2 is the sectional view along A-A line in Fig. 1.
Embodiment
According to drawings and embodiments the utility model is described in further detail below.
As shown in Figure 1 to Figure 2, a kind of piping flange described in the utility model embodiment, comprises the flange body 1 of orate 2, and described flange body 1 is close to the slot 3 that inner edge axially protrudes out a plurality of circular arcs, between described slot 3 and described flange body 1, is provided with stiffening rib 4.
The width of rebate of described slot 3 equates with the thickness of pipeline (not shown).Described slot 3 is integral type structure with described flange body 1.Described flange body 1 has at least three slots 3, and described slot 3 is distributed on described flange body 1.Described flange body 1 has six slots 3.Described flange body 1 is equipped with mounting hole 5.
The foregoing is only explanation mode of execution of the present utility model; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
