The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

The embodiment of the utility model provides a pipeline flange structure which can realize pipeline sampling. Referring to fig. 1 to 4, the pipe flange structure includes: the main flange 10 and the sampling flange 20 are of an integrated structure, namely, the main flange 10 and the sampling flange 20 are of an integrated structure, and the processing and the manufacturing are convenient. Fig. 1 is an isometric view of the pipe flange structure, fig. 2 is a top view of the pipe flange structure, fig. 3 is a sectional view A-A in fig. 2, and fig. 4 is a sectional view B-B in fig. 3.

As shown in fig. 3 and 4, a through hole 30 is provided between the inner side wall of the main flange 10 and the inner side wall of the sampling flange 20, and the through hole 30 communicates the main flange 10 and the sampling flange 20. Wherein the main flange 10 is adapted to be arranged on a pipe; the sampling flange 20 is used to mount sampling devices and/or pressure gauges.

In an embodiment of the present utility model, the main flange 10 of the flange structure of the pipe may be disposed on a pipe through which a liquid to be sampled flows; for example, the pipeline can be a pipeline in a wastewater treatment system, and the pipeline can be made of plastic materials such as UPVC, PP or PVDF. That is, the main flange 10 of the pipe flange structure may replace an original flange in a pipe or the pipe flange structure may be newly added to the pipe, and the main flange 10 is located on the pipe.

The pipe flange structure is also provided with a sampling flange 20, and a through hole 30 for communicating the main flange 10 and the sampling flange 20 is established by using the principle of a communicating vessel, and the pipe and the sampling flange 20 can be communicated by using the through hole 30. Moreover, the sampling flange 20 can be communicated with a sampling device and/or a pressure gauge, so that liquid in the pipeline can reach the sampling flange 20 through the through hole 30 and then enter the sampling device and/or the pressure gauge to realize sampling or pressure detection. For example, the sampling flange 20 is provided with two sides (an upper side and a lower side as shown in fig. 3) capable of mounting other components in the axial direction, and the sampling device and the pressure gauge can be mounted on the two sides of the sampling flange 20, respectively. For example, a sampling valve is arranged on the lower side surface of the sampling flange, and sampling is realized by controlling the sampling valve; the pressure gauge is arranged on the upper side of the sampling flange 20, so that a user can check the pressure in the pipeline at any time conveniently, and an isolation valve can be arranged between the pressure gauge and the sampling flange 20, thereby facilitating overhaul and the like. When the sampling flange 20 is only required to be provided with one of the sampling device and the pressure gauge, one side of the sampling flange 20 in the axial direction may be of a closed structure, or a blind flange may be provided.

Wherein, the material of this pipeline flange structure can be the same with the material of pipeline. Optionally, in order to ensure that the pipeline flange structure also meets the requirements of corrosion resistance and the like, the material of the pipeline flange structure can be UPVC, PP or PVDF. For example, the main flange 10 and the sampling flange 20 are made of the same material and are UPVC, PP, or PVDF.

The pipeline flange structure provided by the embodiment of the utility model comprises a main flange 10 used for being installed on a pipeline and a sampling flange 20 used for being installed with a sampling device and/or a pressure gauge, and the main flange 10 and the sampling flange 20 are communicated through a through hole 30 by utilizing the communicating vessel principle, so that the sampling of the pipeline can be realized by utilizing the sampling flange 20. The pipeline flange structure is simple in structure and low in cost; and only through holes 30 are formed between the two flanges, so that the performance reliability is high, and faults are not easy to occur. In addition, the appearance of the pipeline flange structure is easy to design, and the pipeline flange structure has certain aesthetic property.

Optionally, since the through hole 30 is located inside, it is not easy to directly process, and to facilitate processing of the through hole 30, the sampling flange structure has a through hole 40 coaxial with the through hole 30, and further includes a blocking member. Specifically, as shown in fig. 1, 3 and 4, a through hole 40 communicating with the outside is formed on one side of the sampling flange 20 away from the through hole 30, and the through hole 40 is coaxially disposed with the through hole 30; the blocking member is disposed at the through hole 40 for blocking the through hole 40.

In the embodiment of the utility model, the inner side wall of the sampling flange 20, which is close to the main flange 10, is provided with the through hole 30, and the side, which is far away from the through hole 30 (i.e. the side, which is far away from the main flange 10), is provided with the coaxial through hole 40, so that the through hole 40 and the through hole 30 can be machined at one time, and the machining is convenient. In addition, in order to avoid leakage of the sampling flange 20, the through hole 40 is also plugged by a plugging member, so as to ensure the sealing effect of the sampling flange 20. Wherein the closure is not shown in the figures.

Alternatively, the plug may be a plug, and the end of the through-hole 40 near the outside is an internal thread interface. As shown in fig. 4, the outermost end of the through hole 40 is an internal thread interface, and a plug with an external thread can be arranged in the internal thread interface in a matching way, so that the through hole 40 is plugged to realize sealing.

Optionally, as shown, at least one turn of the first waterline 101 is provided on both axial sides of the main flange 10. Wherein the plurality of first water lines 101 may be concentric annular. Similarly, at least one ring of second water lines 201 is provided on both axial sides of the sampling flange 20, and multiple rings of second water lines 201 may be concentric annular rings. The first water line 101 facilitates sealing between the main flange 10 and the pipe and the second water line 201 facilitates sealing between the sampling flange 20 and the sampling device and/or pressure gauge.

Optionally, for convenience in processing and manufacturing, the main flange 10 of the pipe flange structure is parallel to the axial direction of the sampling flange 20, and the main flange 10 and the sampling flange 20 are located on the same plane. As shown in fig. 3, the main flange 10 is parallel to the sampling flange 20 as a whole, with the two flanges being disposed side by side. Further optionally, the through holes 30 are arranged in the radial direction of the main flange 10 and the sampling flange 20. For example, as shown in fig. 4, the radial directions of the main flange 10 and the sampling flange 20 are left and right, and the through holes 30 are arranged in the left and right directions, for example, the through holes 30 are perpendicular to the two flanges.

Optionally, the size of the main flange 10 is larger than the size of the sampling flange 20. In the embodiment of the utility model, in order to save cost and reduce material consumption, the size of the sampling flange 20 only needs to be capable of realizing sampling, and the size of the sampling flange 20 is not required to be the same as that of the main flange 10, and in general, the size of the sampling flange 20 is smaller than that of the main flange 10.

The geometric dimensions of the inner diameter, the outer diameter, the center distance of screw holes and the like of the main flange 10 and the sampling flange 20 can be selected according to the selected pressure grade standard. For example, the sampling flange 20 may be of a size DN15 (15 mm inner diameter) or DN25 (25 mm inner diameter).

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art can easily think about variations or alternatives within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
