Description

Technical Field

[0001] This utility model relates to the field of flow meter technology, specifically to an insertion vortex flow meter. Background Technology

[0002] An insertion vortex flow meter works by inserting a vortex velocity probe into a pipe. When fluid flows past the probe, alternating vortices are formed behind it. The frequency of these vortex shedding is proportional to the fluid velocity. By measuring the vortex shedding frequency, the fluid velocity can be calculated, and then the volumetric flow rate can be calculated based on the pipe cross-sectional area.

[0003] Existing vortex flow meters are typically fixed directly to pipelines via flanges, using the flow meter's sensor to measure the fluid inside the pipeline. However, malfunctions can occur during flow meter use, requiring subsequent maintenance. The traditional fixing method makes disassembly and assembly inconvenient, requiring the flange to be removed from the pipeline, which is time-consuming and labor-intensive. Therefore, subsequent maintenance is inconvenient and time-consuming, failing to meet usage requirements. To address the shortcomings of existing technology, this invention provides an insertion-type vortex flow meter to solve the above problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This application provides an insertion vortex flow meter, which solves the problem that existing flow meters are usually directly fixed to the pipeline by flanges, and then use the flow meter's sensor to measure the fluid inside the pipeline. However, since the flow meter may malfunction during use, subsequent maintenance is required. The traditional fixing method makes it inconvenient to install and remove the flow meter, resulting in inconvenient subsequent maintenance, time-consuming and labor-intensive maintenance work, and thus failing to meet the usage requirements.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] This utility model discloses an insertion-type vortex flow meter, according to the attached... Figure 1-4 As shown, it includes a loading base 1 fixed on the pipeline, a positioning docking platform 2 fixedly connected to the loading base 1, a docking pressure plate 3 movably engaged on the positioning docking platform 2, a flow meter body 4 provided on the docking pressure plate 3, and the flow meter body 4 movably inserted into the interior of the loading base 1.

[0027] A locking unit is provided between the positioning docking platform 2 and the docking pressure plate 3. The locking unit includes:

[0028] The limiting block 5 is set on the docking pressure plate 3, and the limiting block 5 is provided with a locking groove 501;

[0029] The limiting sleeve 6 is set on the positioning docking platform 2, and the limiting block 5 is movably inserted into the limiting sleeve 6;

[0030] The wedge block 7 is movably inserted into the limiting sleeve 6 and the locking groove 501. The wedge block 7 is used to lock the position of the limiting block 5.

[0031] Furthermore, the locking unit also includes an adjusting seat 701 set on the positioning docking platform 2. An adjusting block 702 is slidably connected inside the adjusting seat 701. A connecting arm 703 is fixedly connected to the adjusting block 702. The connecting arm 703 is fixed to the wedge block 7. The locking unit has a simple structure and is easy to use. The design of the adjusting seat 701, adjusting block 702 and connecting arm 703 makes it easy to provide support and limit the wedge block 7, so that the force on the wedge block 7 is stable and the lateral adjustment process of the wedge block 7 is convenient.

[0032] Furthermore, the wedge block 7 is internally rotatably connected to a double-threaded screw 704, which is threadedly connected to the adjusting block 702. The double-threaded screw 704 facilitates the displacement adjustment of the adjusting block 702. Therefore, the adjusting block 702 drives the connecting arm 703 and the wedge block 7 to move, making the position adjustment of the wedge block 7 convenient, thus making the locking or unlocking operation of the locking unit convenient.

[0033] The double-threaded lead screw 704 is equipped with a rotating handle 705, which makes the rotation of the double-threaded lead screw 704 easier and more convenient.

[0034] Specifically, flanges 101 are fixedly connected to both sides of the loading base 1, which makes it easy to fix the loading base 1 to the pipeline.

[0035] Furthermore, a sealing ring 201 is fixedly connected to the positioning docking platform 2. The sealing ring 201 ensures a stable connection and good sealing between the positioning docking platform 2 and the docking pressure plate 3.

[0036] This insertion-type vortex flow meter connects the entire device to the pipeline via the loading base 1. The sensor of the flow meter body 4 enters the loading base 1 for flow measurement through the docking of the positioning docking platform 2 and the docking pressure plate 3. The locking unit design makes the disassembly and locking process of the positioning docking platform 2 and the docking pressure plate 3 convenient, thus making the disassembly and assembly of the flow meter body 4 easy and facilitating subsequent inspection and maintenance of the flow meter body 4, meeting the usage requirements.

[0037] When inserting the flowmeter body 4 into the loading base 1, first insert the sensor end of the flowmeter body 4 into the loading base 1, and at the same time, make the positioning docking platform 2 and the docking pressure plate 3 dock and fit together. The docking pressure plate 3 drives the limiting block 5 to insert into the limiting sleeve 6. At this time, rotate the double threaded screw 704, so that the double threaded screw 704 drives the adjusting block 702 to move. The adjusting block 702 drives the connecting arm 703 to move. The connecting arm 703 drives the wedge block 7 to move. Therefore, by inserting the wedge block 7 into the locking groove 501, the positions of the limiting block 5, the docking pressure plate 3 and the flowmeter body 4 are fixed. When the flowmeter body 4 needs to be disassembled later, the loading process is reversed.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
