Abstract
The utility model relates to the technical field of production equipment in chemical engineering, petroleum and the like, in particular to a pipeline flange, which comprises a flange body, wherein a pipe interface connected with an external pipeline is arranged on the flange body, and the pipe interface and the flange body form an integral structure. In the pipeline flange, the flange body and the pipe interface form the integral structure, the pipe interface is in a necked structure, when the pipeline flange is communicated with a conveying pipeline, alignment can be conveniently performed for butt welding, and the sealing performance can be simultaneously and effectively improved, thereby reducing the possibility of the leakage of the pipeline.
Description
Technical field
The utility model relates to the technical field of manufacturing mechanisms such as chemical industry, oil, especially a kind of piping flange.
Background technique
Flange is to make pipe and the interconnective part of pipe, is connected in pipe end, is applicable to that the pipeline of various devices such as oil, chemical industry, petrochemical industry, water power, light textile, nuclear energy and pharmacy connects.
Being connected between present most of pipe and the valve, between pipe and the pipe all is that pipe and flange body are directly welded, its structure is pipe and flange directly to be carried out electric welding or fail to explode to weld being connected, thereby reach the purpose of sealing, such connection, during its butt welding weld bond is difficult for aiming at its complicated operation, and poor sealing performance, leak easily, the pressure that weld can bear is little.
The model utility content
The technical problems to be solved in the utility model is: in order to overcome the above-mentioned middle problem that exists, a kind of good seal performance is provided, is difficult for leaking and piping flange simple to operate.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of piping flange, comprise flange body, and described flange body is provided with the tube-like interface that is connected with external pipe, and described tube-like interface and flange body are overall structure.
In order to make things convenient for pipeline and piping flange to peg graft, described tube-like interface is the reducing shape, with the bore of the tube-like interface of the flange body connecting end bore greater than the tube-like interface the other end.
Described flange body is flat flange, processes by forging.
Be evenly distributed with at least two symmetrical through holes around the center of circle on the described flange body.
Described number of openings is 8.
Described flange is made by steel, and steel are Q235-A level steel.
The beneficial effects of the utility model are, piping flange of the present utility model, adopting flange body and tube-like interface is overall structure, tube-like interface is a reducing shape structure, when piping flange is connected with conveyance conduit, can conveniently aim at and carry out butt welding, can effectively improve sealability simultaneously, thereby be difficult for causing the leakage of pipeline.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. flange bodies among the figure, 11. through holes, 2. tube-like interface.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Piping flange as shown in Figure 1, comprise the flat flange body of making by steel 1, be fixed with the reducing shape tube-like interface 2 that is connected with external pipe on the flange body 1, with the bore of the tube-like interface 2 of flange body 1 connecting end bore greater than tube-like interface 2 the other ends, tube-like interface 2 is an overall structure with flange body 1, is evenly distributed with eight symmetrical through holes 11 around the center of circle on the flange body 1.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
