The utility model relates to a kind of duct survey flanged fittings, it is characterized in that it includes flanged fitting, flanged fitting is L shape, flanged pipe is integrated chemical conversion shape, L shape through-hole is equipped in flanged fitting, it is circle in the base portion of flanged pipe, the base portion of flanged pipe is equipped with a measurement recirculation hole being connected to L shape through-hole, and the base portion even circumferential of the flanged pipe on the outside of measurement recirculation hole is respectively equipped with several threaded holes.The utility model has the advantages that hidden danger of quality can be eliminated.
Description
Technical field
The utility model relates to a kind of flanged fitting more particularly to a kind of duct survey flanged fittings.
Background technique
When needing to measure rate-of flow in pipeline, optimal measurement direction is parallel to flow direction of medium, such as
Shown in Fig. 1, existing duct survey flanged fitting is made of three parts: elbow 1, tube socket 2 and flange 3, elbow 1, tube socket 2 and flange
It is linked together between 3 by the method welded.This structure, the welding of tube socket 2 and elbow 1, since the problem of angle causes
Welding fabrication is of poor quality, can not accurately RT detect to check weldquality, so that the elbow 1, tube socket 2 and flange 3 be caused to form
Duct survey flanged fitting there are hidden danger of quality.
Summary of the invention
For disadvantage mentioned above, the purpose of this utility model is to provide a kind of duct survey flanges that can eliminate hidden danger of quality
Pipe fitting.
The technology contents of the utility model are a kind of duct survey flanged fitting, it is characterized in that it includes flanged fitting, method
Blue pipe fitting is L shape, and flanged pipe is integrated chemical conversion shape, and L shape through-hole is equipped in flanged fitting, is circle in the base portion of flanged pipe
The base portion of shape, flanged pipe is equipped with a measurement recirculation hole being connected to L shape through-hole, the bottom of the flanged pipe on the outside of measurement recirculation hole
Portions even circumferential is respectively equipped with several threaded holes.
The utility model compared with prior art possessed by advantage are as follows: the utility model use integrated design,
Welding quality hidden danger is avoided, when for pipeline medium measurement, is greatly improved its reliability；The base portion of flanged pipe is logical
The threaded hole for crossing setting is connected with measuring device, and measurement recirculation hole is for measuring the data such as flow or the pressure of flow media.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing duct survey flanged fitting.
Fig. 2 is the structural schematic diagram of the utility model.
Fig. 3 is the right view of Fig. 2.
Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of flange for pipeline connection pipe fitting, it is characterized in that it includes flanged fitting 11, method
Blue pipe fitting 11 is L shape, and flanged pipe 11 is integrated chemical conversion shape, L shape through-hole 11.1 is equipped in flanged pipe 11, in flanged pipe 11
Base portion 11.2 is circle, and the base portion 11.2 of flanged pipe 11 is equipped with a measurement recirculation hole 11.3 being connected to L shape through-hole 11.1,
Several threaded holes 11.4 are respectively equipped in 11.2 even circumferential of base portion of the flanged pipe 1 in 11.3 outside of measurement recirculation hole.
