Abstract
The utility model relates to a pipe flange. The pipe flange comprises a flange body with a containing opening, wherein the flange body is provided with a threaded hole, the junction surface of the flange body is provided with a cylindrical protruding edge, the surface of the cylindrical protruding edge is provided with an external thread, and the side wall of the containing opening is provided with a flexible plastic lining layer. According to the pipe flange, on one hand, the flexible plastic lining layer is arranged on the containing opening to prevent abrasion of pipes and also to prevent the phenomenon that a medium expands due to an excess temperature and bursts weld joints; on the other hand, the thread is arranged outside the protruding edge so that the protruding edge can be connected with another corresponding pipe flange in a screwing mode, and the connection is convenient and quick.
Description
Technical field
The utility model relates to a kind of pipe joint, relates in particular to a kind of piping flange.
Background technique
It is exactly two pipelines, pipe fitting or equipment that flange connects, and is first fixed on separately on a flange plate, between two flange plate, adds flange gasket, is bolted together, and has completed connection.Some pipe fittings and equipment have carried flange plate, also belong to flange and connect.The pipeline that is applicable to the various devices such as oil, chemical industry, water power, light textile, nuclear energy and pharmacy connects.
At present, in pipeline and flange connection procedure, the pipeline of particularly making for metallic material, and between flange, easily produce wearing and tearing, if conveying is high temperature media, pipeline meeting expanded by heating, at pipeline and flange connections, can cause weld seam to open, reduce its sealing effect.
Model utility content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of piping flange is provided.
The utility model is to be achieved through the following technical solutions:
A piping flange, comprises the flange body with birdsmouth, and described flange body is provided with tapped hole, and the junction surface of described flange body is provided with cylindric flange, and described ledge surface is provided with outside thread, and the sidewall of described birdsmouth is provided with inside liner.
Further, described cylindric flange is provided with seal ring, and described seal ring is "O"-ring.
Further, described inside liner is that flexible plastic material is made.
Further, the thickness of described inside liner is 4mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model, on the one hand by flexiplastic inside liner is set at birdsmouth, prevents pipe wear, prevent from expanding the generation of weld seam distending phenomenon because of the too high generation of medium temperature simultaneously; By being arranged on flange, screw thread is set outward on the other hand, flange can be screwed to connection with another corresponding flange, easy to connect quick.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of piping flange, comprise the flange body 1 with birdsmouth 2, described flange body 1 is provided with tapped hole 3, the junction surface of described flange body 1 is provided with cylindric flange 4, described flange 4 surfaces are provided with outside thread 5, on another piping flange of correspondence, are provided with the groove corresponding with flange, and internal thread is set in groove, flange 5 and groove are screwed, can complete the connection of two piping flanges.
The sidewall of described birdsmouth 2 is provided with inside liner 7, and described inside liner 7 is made for flexible plastic material, and the thickness of described inside liner 7 is 4mm.The utility model arranges flexiplastic inside liner 7 by the birdsmouth 2 at pipeline and flange connections, prevents pipe wear, prevents from expanding the generation of weld seam distending phenomenon because of the too high generation of medium temperature simultaneously.
Described cylindric flange 4 is provided with seal ring 6, and described seal ring 6 is "O"-ring, good sealing effect.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
