Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, in particular to a flow meter which is easy to install. Background Art

[0002] In order to monitor the state of the fluid in the pipeline, various flow meters are installed in the pipeline, and the sensor is separated from the rotating structure by a distance. When the fluid is transported in the pipeline, the flow meter processing circuit generates flow according to the pulse sensing signal.

[0003] For example, Chinese patent application No. 202221334072.6 discloses a flow meter that is easy to install quickly. By pre-connecting a connecting clamp tube to the pipeline, multiple fixed racks are arranged at both ends of the flow meter body, and a rack groove that matches the fixed rack is opened on the outer surface of the connecting clamp tube. When installation is required, the fixed rack only needs to be inserted into the connecting clamp tube along the rack groove to connect the flow meter body. The elasticity of the sealing gasket between the connecting clamp tube and the flow meter body can support the fixed rack to fit tightly with the rack groove. Finally, the threaded ring is rotated to the end of the fixed rack to prevent the fixed rack from being separated from the rack groove, and the connection is more stable.

[0004] In the above solution, the flow meter is fixed to the pipeline by hot-melt welding or other methods, and the monitoring rod is inserted into the pipeline. During use, impurities or corrosive substances contained in the sewage will corrode or stick to the surface of the monitoring rod, and it needs to be removed from the pipeline for cleaning and maintenance. In order to solve the above problems, we have designed a flow meter that is easy to install. Utility Model Content

[0024] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the following.

[0025] See also Figure 1-3 The embodiment of the utility model proposes a flow meter that is easy to install, including a docking pipe 1 and a flow meter body 3, a connecting sleeve 2 is fixedly connected to the side wall of the docking pipe 1, the connecting sleeve 2 penetrates the side wall of the docking pipe 1, two fixed slots 8 are provided on the connecting sleeve 2, and an annular groove 9 is provided on the upper end of the connecting sleeve 2 in an annular shape, a monitoring probe rod 4 is fixedly connected to the bottom side wall of the flow meter body 3, a sealing cover 5 is fixedly connected to the monitoring probe rod 4, and two fixed plug rods 6 are slidably connected to the sealing cover 5, each fixed plug rod 6 is sleeved with a connecting spring 7, one end of the connecting spring 7 is fixedly connected to the side wall of the fixed plug rod 6, and the other end of the connecting spring 7 is fixedly connected to the side wall of the sealing cover 5, and a sealing ring block 10 arranged in an annular shape is fixedly connected to the inner upper side wall of the sealing cover 5, and a filtering structure is provided on the docking pipe 1.

[0026] See also Figure 1-3The filtering structure includes a filter screen frame 12, which is located in the docking pipe 1. A filter screen 13 is fixedly connected to the inner side wall of the filter screen frame 12. Two mounting blocks 14 are fixedly connected to the side wall of the filter screen frame 12. Bolts 15 are provided on the two mounting blocks 14. Two accommodating grooves 16 are provided at one end of the docking pipe 1. Threaded holes 17 are provided on the two accommodating grooves 16. The side wall surface of the threaded hole 17 is threaded. The bolt 15 is rotated clockwise or counterclockwise to move the bolt 15 out of or into the threaded hole 17, so that the filter screen frame 12 can be removed from or installed on the docking pipe 1.

[0027] See also Figure 1-3 The outer diameter length of the filter frame 12 is the same as the inner diameter length of the docking pipe 1. The filter frame 12 is adapted to the internal size of the docking pipe 1, which can reduce the installation gap. The sewage can only pass through the filter screen 13, thereby improving the filtering effect.

[0028] See also Figure 1-3 A sealing gasket 11 is fixedly connected to the bottom side wall of the sealing ring block 10. The cross section of the sealing gasket 11 is annular. After the sealing gasket 11 is squeezed, the sealing effect between the sealing ring block 10 and the annular groove 9 is increased.

[0029] See also Figure 1-3 Two flanges 18 are fixedly connected to the butt joint pipe 1, and the two flanges 18 are respectively located at both ends of the butt joint pipe 1. It is convenient to connect the butt joint sleeve 1 with the external pipeline.

[0030] See also Figure 1-3 The bottom side walls of the two fixed rods 6 are arranged in an inclined shape. When the sealing cover 5 is inserted into the connecting sleeve 2, the fixed rods 6 can move outward with the extrusion of the connecting sleeve 2 under the guidance of the inclined surface. During installation, there is no need to manually pull the fixed rods 6.

[0031] The working principle of the utility model is as follows: when disassembling the flow meter body 3, the two fixed plug rods 6 are pulled outwards to move the fixed plug rods 6 located in the fixed slots 8 outwards, so that the flow meter body 3 can be removed from the connecting sleeve 2, so that the monitoring probe rod 4 can be maintained. Conversely, the monitoring probe rod 4 is inserted into the connecting sleeve 2, the sealing ring block 10 is inserted into the annular groove 9, and one end of the fixed plug rod 6 is inserted into the fixed slot 8. Under the elastic force of the connecting spring 7, the fixed plug rod 6 is pressed against and does not move outwards, so that the flow meter body 3 and the docking pipe 1 are installed together. At the same time, under the action of the sealing ring block 10, a sealing effect is achieved to prevent the internal liquid from leaking out (see the attached manual). Figure 3The distance between the middle sealing cover 5 and the connecting sleeve 2, and the distance between the sealing ring block 10 and the annular groove 9 is to more conveniently demonstrate the connection relationship between the various components, so that they are normally fitted together). The filter screen 13 can filter the liquid that passes through, reduce the circulation of impurities in the liquid, and reduce the adhesion of impurities to the monitoring probe 4. By rotating the bolt 15 clockwise and counterclockwise, the bolt 15 can be moved out of or into the threaded hole 17, so that the filter screen frame 12 can be removed from or installed on the docking pipe 1, which is very convenient.

[0032] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
