DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: an angular insertion vortex flowmeter, comprising a flowmeter body 1, a fixed outer screw ring 3, an insertion rod 5 and a protective screw barrel 9. The lower end of the flowmeter body 1 is fixed with a mounting flange 13 by means of a sealing rubber 14 and bolts. A metal fixed pipe 2 is integrally arranged in the middle of the lower end of the mounting flange 13. A fixed outer screw ring 3 is fixed to the lower end of the annular side of the metal fixed pipe 2. A leak-proof rubber ring 4 is fixed to the lower side of the fixed outer screw ring 3 by means of epoxy resin glue. A sensor 6 is installed in the insertion rod 5. An outer thread 7 is arranged on the upper end of the annular side of the insertion rod 5. A double screw ring 8 is sleeved on the outside of the insertion rod 5. Sponge rings 10 are fixed to the upper and lower ends of the annular side of the protective screw barrel 9. Rubber cylinders 11 are arranged on the annular sides of the two sponge rings 10. This design solves the problem that the insertion rod and the sensor in the original device are directly exposed to the outside world without any protective structure. Once it is subjected to external collision and other factors, it is very easy to cause damage and water leakage at the connection between the insertion rod and the pipeline.

[0019] As the first embodiment of the utility model: the upper end of the insertion rod 5 is screwed into the metal fixing tube 2 through a thread, and the added metal fixing tube 2 facilitates the insertion rod 5 to be screwed in or removed through a thread. The double screw ring 8 is screwed into the outside of the fixed outer screw ring 3 through a thread, and the leakproof rubber ring 4 is tightly attached to the lower end of the double screw ring 8. The added double screw ring 8 can be screwed into the outside of the fixed outer screw ring 3 through a thread, thereby shielding and protecting the connection between the insertion rod 5 and the metal fixing tube 2, and the double screw ring 8 can also be connected to the protective screw barrel 9 through a thread.

[0020] A plurality of rubber protective rods 12 are installed at equal angles between the two sponge rings 10. The added plurality of rubber protective rods 12 can protect the middle of the outside of the protective screw barrel 9. The annular sides of the two rubber tubes 11 are provided with anti-skid patterns. The added anti-skid patterns make it convenient for the staff to twist the two rubber tubes 11 for rotation, and then facilitate the protection screw barrel 9 to rotate and move through the sponge ring 10. The protection screw barrel 9 is screwed on the outside of the double screw ring 8 through threads, and the metal fixed pipe 2 and the insertion rod 5 are both inside the protection screw barrel 9. The added protection screw barrel 9 can be screwed on the outside of the double screw ring 8 through threads, thereby realizing the protection of the metal fixed pipe 2 and the insertion rod 5. The sponge ring 10, rubber tube 11 and rubber protective rod 12 can reduce the impact of the outside world, thereby enhancing the protection of the protection screw barrel 9 on the lower part of the flowmeter body 1, the insertion rod 5 and the sensor 6.

[0021] As the second embodiment of the present utility model: when it is necessary to assemble and install the device, firstly, screw the insertion rod 5 into the metal fixed tube 2 through the external thread 7. Since the sensor 6 has been fixed in the insertion rod 5, the upper end of the sensor 6 will also be in the metal fixed tube 2. During this process, the double screw ring 8 can be screwed onto the outside of the fixed external screw ring 3 through the thread, and the leak-proof rubber ring 4 will also be in close contact with the lower end of the double screw ring 8, thereby enhancing the sealing between the double screw ring 8 and the fixed external screw ring 3. Then, hold the two rubber tubes 11 and screw the protective screw tube 9 onto the outside of the double screw ring 8 through the thread until the protective screw tube 9 completely covers the insertion rod 5 and the metal fixed tube 2. Then, the protection of the metal fixed tube 2 and the insertion rod 5 can be achieved. The sponge ring 10, rubber tube 11 and rubber protective rod 12 can reduce the impact from the outside, thereby enhancing the protection of the protective screw tube 9 on the lower part of the flowmeter body 1, the insertion rod 5 and the sensor 6.
