[0002] An ultrasonic water meter is a new type of water meter that uses ultrasonic measurement technology to measure the flow rate of water. The ultrasonic water meter measures the flow velocity and flow rate of water by transmitting and receiving ultrasonic signals, and its working principle is based on the relationship between the propagation speed of ultrasonic waves in water and the flow velocity of water.

[0003] When the existing ultrasonic water meter is installed in a water pipeline, it is generally installed on the surface of the pipeline by means of threaded connection. However, during threaded installation, due to long-term use, oxidation may occur at the connection, resulting in rusting of the threaded connection. In order to reduce the degree of oxidation at the connection, we propose an installation structure for an ultrasonic water meter to solve the above problems. Summary of the Utility Model

By setting the sliding of the guide post 13 in the guide groove 12, the up-and-down sliding of the installation connection cylinder 5 is guided and limited, so that the installation connection cylinder 5 is installed on the outer surfaces of the second connecting pipe 4 and the first connecting pipe 2. The initial position of the bottom end face of the installation connection cylinder 5 is above the threaded part of the first connecting pipe 2. The height of the guide groove 12 is greater than the sliding distance of the installation connection cylinder 5 on the surface of the first connecting pipe 2. A threaded hole 6 is opened on the surface of the installation connection cylinder 5. A threaded pipe 7 with a hollow structure is threadedly connected to the surface of the threaded hole 6. A limiting hole 8 is opened at a position on the surface of the second connecting pipe 4 corresponding to the threaded pipe 7. After the threaded pipe 7 slides in the threaded hole 6 and sleeves on the surface of the second connecting pipe 4, it is threadedly connected to the inner surface of the threaded hole 6 by means of threaded rotation, and the opposite end faces penetrate into the inner surface of the limiting hole 8. A filling pad 9 is filled at the outer end face of the threaded pipe 7. A first sealing ring 10 is sleeved on the surface of the first connecting pipe 2. A second sealing ring 11 is sleeved on the surface of the threaded pipe 7. Both the first sealing ring 10 and the second sealing ring 11 are located on the inner surface of the installation connection cylinder 5. The first sealing ring 10 and the second sealing ring 11 are respectively sleeved on the surfaces of the first connecting pipe 2 and the second connecting pipe 4 in advance. The first connecting pipe 2 is installed on the inner surface of the second connecting pipe 4 through the thread on the surface of the first connecting pipe 2. By slidably connecting the installation connection cylinder 5 on the outer surface of the first connecting pipe 2, the installation connection cylinder 5 covers the surface of the second connecting pipe 4. Open the filling pad 9 and inject a certain amount of butter through the threaded pipe 7, so that the butter fills between the first connecting pipe 2 and the second connecting pipe 4, isolating moisture and air and reducing the degree of oxidation. After the injection is completed, rotate the threaded pipe 7 into the inner surface of the threaded hole 6, so that the threaded pipe 7 is stuck into the inner surface of the limiting hole 8, so that the installation connection cylinder 5 is installed on the surface of the second connecting pipe 4.

[0024] Embodiment 2:

[0025] Figures 1-3The ultrasonic water meter installation structure of an embodiment of the present invention is shown. The installation structure is arranged between the water meter 1 and the water pipe 3. The water pipe 3 is located at the bottom of the water meter 1. The installation structure includes a connecting pipe 1 2 fixedly connected to the bottom of the water meter 1. The top of the water pipe 3 is connected to a connecting pipe 2 4. The surface of the connecting pipe 1 2 is slidably provided with an installation connecting cylinder 5. The surface of the installation connecting cylinder 5 is provided with a threaded hole 6. The surface of the threaded hole 6 is threadedly connected to a threaded pipe 7 with a hollow structure. A limiting hole 8 is provided on the surface of the connecting pipe 2 4 and at a position corresponding to the threaded pipe 7. After the threaded hole 6 slides on the surface of the connecting pipe 2 4, the threaded pipe 7 is threadedly connected to the inner surface of the threaded hole 6 by threaded rotation, and the opposite end face passes through the inner surface of the limiting hole 8. The surface of the threaded pipe 7 is fixedly connected to a toggle plate 14 for rotating the threaded pipe 7. By setting the threaded pipe 7 The surface of the screw pipe 7 is fixedly connected with a toggle plate 14 for rotating the screw pipe 7, which can facilitate the installer to rotate the screw pipe 7. When grease needs to be injected, the screw pipe 7 can be rotated so that the screw pipe 7 leaves the inner surface of the limiting hole 8. The toggle plate 14 is located on the outer surface of the installation connecting tube 5, and the opposite ends of the screw pipe 7 extend into the inner surface of the limiting hole 8 by a distance of three to five millimeters. By setting the opposite ends of the screw pipe 7 to extend into the inner surface of the limiting hole 8 by a distance of three to five millimeters, the limiting hole 8 is prevented from penetrating the inner surface of the connecting pipe 2 4, thereby affecting the threaded rotation of the connecting pipe 1 2 on the inner surface of the connecting pipe 2 4. The outer end face of the screw pipe 7 is filled with a filling pad 9, the surface of the connecting pipe 2 is provided with a sealing ring 10, and the surface of the screw pipe 7 is provided with a sealing ring 2 11. The sealing ring 10 and the sealing ring 2 11 are both located on the inner surface of the installation connecting tube 5.

[0026] Working principle: When the present invention is used, the sealing ring 10 and the sealing ring 2 11 are respectively sleeved on the surfaces of the connecting pipe 1 2 and the connecting pipe 2 4 in advance, and the connecting pipe 1 2 is installed on the inner surface of the connecting pipe 2 4 through the thread on the surface of the connecting pipe 1 2, and the connecting tube 5 is installed and slidably connected on the outer surface of the connecting pipe 1 2. The sliding of the guide column 13 in the guide groove 12 guides and limits the up and down sliding of the installing connecting tube 5, so that the installing connecting tube 5 is installed on the outer surface of the connecting pipe 2 4 and the connecting pipe 1 2. The filling pad 9 is opened, and a certain amount of butter is injected through the threaded tube 7 so that the butter is filled between the connecting pipe 1 2 and the connecting pipe 2 4, isolating moisture and air and reducing the degree of oxidation. After the injection is completed, the toggle plate 14 is rotated to make the threaded tube 7 rotate to the inner surface of the threaded hole 6, and then the threaded tube 7 is stuck in the inner surface of the limiting hole 8, so that the installing connecting tube 5 is installed on the surface of the connecting pipe 2 4, which can reduce the degree of oxidation at the connection and reduce the rust of the thread.
