Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flowmeters, in particular to an ultrasonic flowmeter which is easy to install. Background Art

[0002] Ultrasonic flowmeters are primarily used to measure the flow of fluids such as gases or liquids in industrial pipelines. They are fixedly connected to the pipe flanges on either side via fixed flanges at both ends. The two fixed flanges are generally symmetrically arranged, and the screw holes in the fixed flanges are fixed. Once connected to the pipe flange on one side, the flange on the other side is difficult to align with the screw holes in the fixed flanges. The existing technology requires one worker to forcibly rotate the pipe section to align it with the fixed flange on the flowmeter, while another worker screws the pipe flange to the fixed flange. This installation method, on the one hand, forcibly rotating the pipe section can cause varying degrees of damage to the pipe section, especially in cold weather, where the pipe section can crack due to long-term torsional forces. On the other hand, it requires two workers to work together, making installation inconvenient and increasing labor costs. Utility Model Content

[0003] In view of the fact that the existing technology has the problem of difficulty in aligning the measuring pipe with the flanges of the pipe sections on both sides and inconvenient installation, the utility model provides an ultrasonic flowmeter that is easy to install. The split flange at the end of the measuring pipe can adapt to the angular rotation and alignment of the pipe section flange and has strong flexibility.

[0004] The utility model provides an ultrasonic flowmeter that is easy to install, comprising a flow pipe, a fixed flange arranged at one end of the flow pipe, a mounting groove located at the other end of the flow pipe, and a split flange that is snap-fitted and installed in the mounting groove; the split flange comprises a first half flange and a second half flange that is connected to the first half flange, and the first half flange and the second half flange are detachably installed at the end of the flow pipe; after the fixed flange and the pipe section flange on one side are fixedly installed, the first half flange and the second half flange are adapted to the installation angle of the pipe section flange on the other side, and then the first half flange and the second half flange are fixedly connected.

[0005] Furthermore, a first overlapping platform is provided at both ends of the first half flange, and a second overlapping platform is provided at both ends of the second half flange, which is overlapped and installed corresponding to the first overlapping platform; the first overlapping platform and the second overlapping platform are fixedly installed by screws.

[0006] Furthermore, the flow pipe is provided with a transducer mounting threaded hole for mounting the ultrasonic transducer; the angle between the extending direction of the transducer mounting threaded hole and the extending direction of the flow pipe is 45°.

[0007] Furthermore, two sealed wire boxes for loading ultrasonic transducer energy transmission lines are relatively arranged on the flow pipe. A mounting flange for connecting to the flow meter head is installed on the top of the sealed wire box. The ultrasonic transducer energy transmission lines on both sides are connected to the flow meter head through the wire holes on the mounting flange wall.

[0008] Furthermore, ultrasonic transducer covers are provided on both sides of the flow pipe and are fixedly mounted to the flow pipe with screws.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] After fixing the fixed flange at one end of the flow pipe to the pipe section flange on one side, the split flange at the other end of the flow pipe is split apart. The first half flange is first installed into the installation groove and rotated to align with the pipe section flange and then fixed. The second half flange is then installed into the installation groove and adjusted in a small range to align with the pipe section flange and then fixed. Finally, the first half flange and the second half flange are fixed. This structure has strong flexibility and can adapt to pipe sections of various angles. The split flange at the end is detachable and easy to clean. The separation and rotation alignment method conveniently and efficiently realizes the fixed installation of the flow pipe and the pipe section flanges on both sides.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0022] Please refer to Figures 1-4 The utility model provides an ultrasonic flowmeter that is easy to install, including a flow pipe 1, a fixed flange 2 arranged at one end of the flow pipe 1, a mounting groove 4 located at the other end of the flow pipe 1, and a split flange 3 that is snap-fitted and installed in the mounting groove 4; the split flange 3 includes a first half flange 31 and a second half flange 32 that is connected to the first half flange 31, and the first half flange 31 and the second half flange 32 are detachably installed at the end of the flow pipe 1; after the fixed flange 2 and the pipe section flange on one side are fixedly installed, the first half flange 31 and the second half flange 32 are adapted to the installation angle of the pipe section flange on the other side, and then the first half flange 31 and the second half flange 32 are fixedly connected.

[0023] After the first half flange 31 and the second half flange 32 are fixed together, the first half flange 31 and the second half flange 32 are installed in the installation groove 4.

[0024] like Figure 2 and Figure 4 As shown, first overlapping platforms 311 are provided at both ends of the first half flange 31, and second overlapping platforms 321 are provided at both ends of the second half flange 32, which are overlapped and installed corresponding to the first overlapping platforms 311; the first overlapping platforms 311 and the second overlapping platforms 321 are fixed by screws.

[0025] In this embodiment, the split flange 3 can be fixedly installed in the installation groove 4 by overlapping and fixing the first overlapping platform 311 and the second overlapping platform 321, which facilitates the fixed installation of the split flange 3 and the pipeline flange.

[0026] like Figure 3 As shown, the flow pipe 1 has a transducer mounting threaded hole 5 for mounting an ultrasonic transducer; the extending direction of the transducer mounting threaded hole 5 and the extending direction of the flow pipe 1 form an angle of 45°.

[0027] In this embodiment, the ultrasonic transducer transmitting end and the ultrasonic transducer receiving end are respectively installed in the transducer mounting threaded hole 5. Since the extension direction of the transducer mounting threaded hole 5 and the extension direction of the flow pipe 1 are at an angle of 45°, the ultrasonic transducer transmitting end and the ultrasonic transducer receiving end arranged at a 45-degree diagonal angle to each other can receive ultrasonic waves. The two pairs of ultrasonic transducers work simultaneously, and the flow rate and flow of the gas or liquid in the flow pipe 1 are calculated by measuring the time difference between the two sets of transmitted signals; the setting of the two pairs of ultrasonic transducers can ensure the accuracy of the measurement data; the setting of the threaded holes can facilitate the fixed installation of the ultrasonic transducer transmitting end and the receiving end, thereby ensuring the stability of the data.

[0028] like Figure 3 As shown, two sealed wire boxes 6 for loading ultrasonic transducer energy transmission lines are relatively arranged on the flow pipe 1, and a mounting flange 7 for connecting to the flow meter head 8 is installed on the top of the sealed wire box 6. The ultrasonic transducer energy transmission lines on both sides are connected to the flow meter head 8 through the wire holes 71 on the wall of the mounting flange 7.

[0029] In this embodiment, the ultrasonic transducer energy transmission line is connected to the flow meter head 8 through the wire hole 71 between the sealing box 6 and the mounting flange 7. The sealing box 6 is in a completely sealed state to ensure the safety of the ultrasonic transducer energy transmission line.

[0030] like Figure 2 As shown, ultrasonic transducer covers 9 are provided on both sides of the flow pipe 1 and are fixed to the flow pipe 1 with screws.

[0031] In this embodiment, the ultrasonic transducer cover plate 9 protects the internal ultrasonic transducer and prevents the ultrasonic transducer from being damaged by the outside world.

[0032] It should be understood that the specific embodiments described above are only used to explain the present invention and are not intended to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
