Description

[0030] An exemplary embodiment and further advantages of the invention will be discussed below in conjunction with the following figures, In the drawings:

[0031] FIG. 1 shows a schematic, longitudinal section through a flange element according to the invention; and

[0032] FIG. 2 shows a schematic, longitudinal section through a pipe according to the invention.

[0033] The description of the above-mentioned figures is given with reference to cylindrical coordinates with a longitudinal axis X, a radial direction R oriented perpendicularly to the longitudinal axis X, and a circumferential direction (not shown) running around the longitudinal axis X.

[0034] FIG. 1 shows a schematic longitudinal section through a flange element 1 according to the invention. The flange element 1 consists of a flange body 10 made of aluminum, which is produced integrally e.g. as a casting or milled part. Along the longitudinal axis X, the flange body 10 has a media passage opening 11 through which a medium, e.g. a fluid, can flow in a flow direction A (or in the opposite direction), as will be explained in more detail with reference to FIG. 2. In the illustration of FIG. 1, a pipe receiver 12 is provided which can receive a pipe element 3, as will also be explained in more detail with reference to FIG. 2. The pipe receiver 12 is here configured as a recess or depression.

[0035] On the opposite side along the longitudinal axis X, the pipe receiver 12 has a guide element 13 which points away from the flange body 10 as an annular protrusion and is configured to be introduced into a corresponding opening of a connection partner such as e.g. an apparatus (not shown). A sealing ring body 40, which is closed in the circumferential direction, of a sealing element 4 may be arranged round the guide element 13, see FIG. 2.

[0036] A lateral sensor passage opening 14 extends perpendicularly or radially to the longitudinal axis X, and is shown pointing to the left in FIGS. 1 and 2. The sensor passage opening 14 is introduced into the flange body 10 as a bore laterally towards the radial inside, and thus connects the media passage opening 11 radially to the environment of the flange element 1. On the radial outside, a lateral sensor receiver 15 adjoins the sensor passage opening 14; this receiver is formed significantly larger than the sensor passage opening 14 in the circumferential direction (not shown) and along the longitudinal axis X, so that a sensor 2 or its sensor housing 20 can be received therein. A sensor element 21 of the sensor 2 may in this way extend through the sensor passage opening 14 into the media passage opening 11, as will be described in more detail below with reference to FIG. 2.

[0037] During drilling, a further bore is made through the sensor passage opening 14 into the material of the flange body 10 on the radially opposite side of the media passage opening 11, forming a pulsation damping chamber 16. The pulsation damping chamber 16 may be formed open as shown in FIGS. 1 and 2, or be provided with a Helmholtz resonator or a damping membrane (not shown). In this way, pulsations in the medium flowing through the media passage opening 11 can be damped.

[0038] The flange body 10 furthermore has a connection passage opening 17 which runs parallel to the media passage opening 11. A connecting element, e.g. a bolt, can be guided through the connection passage opening 17 in order to attach the flange element 1 and its connected pipe element 3 to a connection partner (not shown) such as e.g. an apparatus.

[0039] FIG. 2 shows a schematic longitudinal section through a pipe 1, 3 according to the invention. The pipe 1, 3 comprises the above-mentioned pipe element 3 which is made of an integral, cylindrical pipe body 30 of aluminum extending along the longitudinal axis X. The pipe body 30 may also be described as a pipe wall 30. The hollow interior of the pipe body 30 forms its media passage opening 31, which has the same cross-section as the media passage opening 11 of the flange body 10. The pipe element 3 may comprise further elements such as e.g. retention and connection elements (not shown) and similar.

[0040] The pipe body 30 is inserted with an open end in the pipe receiver 12 of the flange body 10 during installation. The pipe body 30 and the flange body 10 are there welded together e.g. by laser welding, so as to form a substance-bonded connection 32 in the form of a weld connection 32. This forms a one-piece pipe 1, 3.

[0041] Then the above-mentioned sensor 2 is inserted from the radial outside into the lateral sensor receiver 15 of the flange element 1, so that the sensor housing 20 in the lateral sensor receiver 15 lies thereon both radially and in the circumferential direction and along the longitudinal axis X. The sensor 2 may be fixed there, e.g. by gluing. At the same time, the sensor element 21, which may also be described as a measurement probe 21, protrudes radially inwardly into the media passage opening 11 of the flange body 10, so that the medium can flow around the measurement probe 21 or its measurement tip (not designated). This may allow the measurement probe 21 to detect properties of the medium, e.g. its temperature, flow speed and similar. The measurement probe 21 is here glued in the sensor passage opening 14 so as to achieve a secure retention and media-tight seal.

[0042] Towards the radial outside, the sensor 2 has a pair of plug contacts 23 which serve for connection of a corresponding plug connector, e.g. for electrical energy supply to or data exchange with the sensor 2. The plug contacts 23 are surrounded by a plug collar 22 for protection.

[0043] In this way, a pipe 1, 3 can be produced which may be connected to a connection partner by means of a flange 1 as previously known. This may take place as described above, e.g. by means of a bolt through the connection passage opening 17. At the same time, a seal can be made against the connection partner, such as e.g. an apparatus, by means of the above-mentioned sealing element 4. Furthermore, the measurement probe 21 may be arranged such that the measurement probe 21 or its measurement tip can reach the medium and sensorily detect at least one property of the medium. This may take place media-tightly. At the same time, this can be achieved comparatively easily since only the flange element 1 need be machined for this, instead of the pipe element 3. This can not only keep the production costs down but also avoid potential leakage points.
