Abstract
The utility model provides a flange connecting device applicable to different standard systems, belonging to the field of chemical industry. The flange connecting device comprises a pair of flanges and two sections of pipelines belonging to different standard systems, wherein both of the flanges comprise flange faces and flange necks and are used for connecting the metal pipelines belonging to different standard systems, the connecting faces of the flanges are a pair of flange faces, and the flange faces are manufactured according to the structural specification form of one of the standard systems; one of the flange necks is designed into a size form matched with the inner diameter and the outer diameter of the first pipeline, and the other flange neck is designed into a size form matched with the inner diameter and the outer diameter of the second pipeline. Thus, the two sections of pipelines belonging to different standard systems can be connected through the flanges, and the specifications of the two sections of pipelines are similar. The utility model enables the installation of pipelines and pipe fittings in the chemical industry to be more convenient and flexible, and solves the technical difficulty that only parts meeting same system standard can be used in the installation of pipelines and the installation of pipelines and equipment in the traditional chemical technology.
Description
Technical field
The utility model relates to chemical field, particularly a kind of flange connecting apparatus that is applicable to different standard systems.
Background technique
It is exactly two pipelines, pipe fitting or equipment that flange connects, and is fixed on separately on the flange plate earlier, between two flange plate, adds flange gasket, with bolton together, has finished connection.In other words, flange connects and to be meant by flange, pad and bolt three and to interconnect releasable connection as one group of combined sealing structure that piping flange is the flange that pipe arrangement is used in the tube equipment, is used in the inlet/outlet flange of the equipment that means on the equipment.Flange connects easy to use, can bear bigger pressure.In industrial pipeline, especially the use that flange connects in chemical plant installations is very extensive.
1), European flange standards system: German DIN (comprising Soviet Union's standard) kind and the standard of flange are a lot, comprise NBS and international standard, and the system of pipe flange standard commonly used has following:; 2), America flange system: U.S. ANSIB16.5 " steel pipe flanges and flanged fitting "; 3), China's steel pipe flanges NBS system GB flange etc.The flange standards system of various countries' application has many, different national different industries that different application standards and standards system are arranged in the world, and some is mutually far short of what is expected between them, brings many troubles to the user.
At present, the domestic pressure piping and the application standard of element thereof also have a lot, and be all imperfect again.With the pipe flange standard is example, and standard commonly used just has NBS (GB), mechanical industry standard (JB), petrochemical industry standard (SH) and chemical industry standard (HG) etc.These standards respectively have temperature, pressure, size of seal contact face and adapter size separately, and interchangeability is poor each other, some in addition can not supportingly use.
The matter of utmost importance of pressure piping design is selected the application standard system exactly, and often can occur the pipeline or the flange of different standards systems in design, can not exchange when it is installed.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of flange connecting apparatus that is applicable to different standard systems.
The technical solution of the utility model is as follows:
A kind of flange connecting apparatus that is applicable to different standard systems, comprise a pair of flange, two segment pipes of different standard systems, described a pair of flange is formed by flanged surface and neck flange, the metallic conduit that is used for different standard systems leads to and connects, the face that described a pair of flange is connected is a pair of flanged surface, described flanged surface is by wherein a kind of structure and specification form manufacturing of standards system, described a slice neck flange be designed to first kind of pipeline in the size form that is complementary of external diameter, described another sheet neck flange be designed to the secundal viae road in the size form that is complementary of external diameter, two segment pipes that can connect described different standard systems by described a pair of flange, described two segment pipe specifications are close, but it does not belong to same standards system, as an Europe superscript pipeline and a U.S. mark pipeline.
The beneficial effects of the utility model are:
This pipe flange can satisfy between the different standard systems pipeline simultaneously, or being connected between pipeline and the equipment interface flange, at process pipe with more convenient and flexible during the installation of equipment is connected.
Description of drawings
Figure is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail.
As shown in the figure, the utility model comprises a slice flange 1, a slice flange 2, one Europe superscript pipeline 6, one U.S. mark pipeline 7, flanged surface 3, neck flange 4, neck flange 5, flange 1, flange 2 is respectively by flanged surface 3 and neck flange 4, flanged surface 3 is formed with neck flange 5, flanged surface 3 is pressed the structure and specification form of Europe superscript and is made, the neck flange 5 of flange 2 is designed to mark the size form that external diameters are complementary in the pipeline 7 with U.S., the neck flange 4 of flange 1 be designed to Europe superscript pipeline 6 in the size form that is complementary of external diameters, two segment pipes by flange 1 and flange 2 these two kinds of different standard systems of connection promptly connect Europe superscript pipeline 6, U.S. mark pipeline 7.Europe superscript pipeline 6 and U.S. mark pipeline 7, this two segment pipes specification is close.
This flange is by the application in installation of chemical process pipe line, make the easier for installation flexible of chemical pipeline, pipe fitting, improved chemical industry equipment, the working efficiency when process pipelines is installed, solved in the past between the chemical process pipeline, must adopt the narrow limitation with a kind of system standard piece when installing between pipeline and the equipment.The utility model is applicable to the installation of chemical industry equipment, process pipelines, and the structural feature of this flange greatly facilitates engineering construction, uses commonplace.
Claims (1)
