Technical Field

[0001] This utility model relates to the field of flow meter installation technology, specifically to a quick-installation structure for a flow meter. Background Technology

[0002] A flow meter is an instrument that indicates the measured flow rate and / or the total fluid volume within a selected time interval. Simply put, it's an instrument used to measure the flow rate of fluid in pipes or open channels. Flow meters are further classified into differential pressure flow meters, rotor flow meters, throttling flow meters, slot flow meters, volumetric flow meters, electromagnetic flow meters, ultrasonic flow meters, etc. They can also be classified by medium: liquid flow meters and gas flow meters. In urban water supply and drainage systems, they can accurately measure water flow, providing a basis for water resource management and water fee collection. The following problems exist with existing technologies: Existing flow meters require multiple bolts to connect to the pipeline during use, which involves additional tools, making installation complex, time-consuming, and labor-intensive. Furthermore, the lack of a sealing and positioning structure between the flow meter and the pipeline during installation results in poor positioning of the sealing ring, affecting the sealing effect.

After the water supply pipe 3 and the connecting pipe 4 are connected by a clamp, the locking component 5 is installed at the connection between the water supply pipe 3 and the connecting pipe 4, which enables quick installation between the flow meter dial 1 and the water supply pipe 3.

[0017] like Figure 2 As shown, this utility model provides a quick-installation structure for a flow meter: the locking component 5 includes a semi-circular clamp 51, a semi-circular clamp 52, a fixing block 53, an L-shaped fixing plate 54, a stud 55, and a knob 56. One end of the fixing block 53 is fixedly connected to one end of the outer wall of the semi-circular clamp 51. One end of the horizontal surface of the L-shaped fixing plate 54 is fixedly connected to one end of the outer wall of the semi-circular clamp 52. One end of the stud 55 is fixedly connected to one end of the knob 56. The left and right sides of the inner walls of the semi-circular clamp 51 and the semi-circular clamp 52 are respectively provided with slots 57. The middle side of the L-shaped fixing plate 54 in the vertical direction is provided with an insertion hole 540 that is adapted to the stud 55 and is through the front and back. The outer wall of the fixing block 53 is provided with a threaded hole 530 corresponding to the insertion hole 540. The outer wall of the stud 55 passes through the insertion hole 540 and is threadedly connected to the inner wall of the threaded hole 530. Fixing is achieved by a single stud 55, which further speeds up the installation efficiency.

[0018] like Figure 3 As shown, this utility model provides a quick-installation structure for a flow meter: a connecting block 511 is fixedly connected to the end of the outer wall of a semi-circular clamp 51 away from the fixing block 53, and a connecting plate 521 is fixedly connected to the end of the outer wall of a semi-circular clamp 52 away from the L-shaped fixing plate 54. The connecting plate 521 is L-shaped, and a groove 5210 matching the connecting block 511 is opened at the top vertical direction of the connecting plate 521. The left and right ends of the outer wall of the connecting block 511 are rotatably connected to the inner wall of the groove 5210. The semi-circular clamp 51 rotates along the groove 5210 through the connecting block 511, which can realize the opening and closing effect between the semi-circular clamp 51 and the semi-circular clamp 52.

A retaining ring 43 is fixedly connected to the outer walls of the two mounting sleeves 41 on opposite sides. An annular groove 410 is provided on the inner wall of the two mounting sleeves 41 near the connecting pipes 4. The annular groove 410 serves to position the connection between the connecting pipes 4 and the water supply pipe 3. The inner wall of the groove 57 engages with the outer wall of the retaining ring 43, thus locking the component 5 to the outer wall of the connecting pipes 4 and limiting its installation.

A sealing ring 34 matching the annular retaining groove 410 is fixedly connected to the side of the outer wall of the tube 31 away from the positioning collar 32. The outer wall of the tube 31 is sleeved with the inside of the mounting sleeve 41. The outer surface of the sealing gasket 42 overlaps with one end of the positioning collar 32. The outer wall of the sealing ring 34 engages with the inner wall of the annular retaining groove 410. The sealing ring 34 snaps into the annular retaining groove 410, thereby sealing and positioning the tube 31 and the mounting sleeve 41, achieving a tight fit between the sealing gasket 42 and the positioning collar 32.

[0021] The working principle of this quick-installation flow meter structure will be explained in detail below.

[0022] like Figure 1-5 As shown, when installing the flow meter, firstly, the water supply pipe 3, which is matched with the flow meter, is inserted into the installation housing 41 through the insertion tube 31. The sealing ring 34 is then positioned by pushing the water supply pipe 3 into the annular groove 410. Then, the sealing gasket 42 at one end of the installation housing 41 is tightly fitted to the surface of the positioning ring 32. Next, the semi-circular clamp 51 is opened along the groove 5210 through the connecting block 511, and the semi-circular clamp 52 is placed below the connection between the installation housing 41 and the insertion tube 31. The retaining ring 43 on the lower surface and the retaining ring 33 respectively engage with the retaining ring 43 in the semi-circular clamp 52. The groove 57 is then inserted, and then the semi-circular clamp 51 is fastened above the connection between the mounting sleeve 41 and the flow meter dial 1. The retaining ring 43 and retaining ring 33 on the upper surface are respectively engaged in the groove 57 in the semi-circular clamp 51. The fixing block 53 is engaged in the inner surface of the L-shaped fixing plate 54. The threaded hole 530 and the insertion hole 540 are aligned. Finally, the stud 55 is inserted from front to back along the insertion hole 540 into the threaded hole 530 and screwed in to lock the semi-circular clamp 51 and the semi-circular clamp 52. The operation is simple, time-saving and labor-saving, and realizes the rapid installation between the flow meter dial 1 and the water supply pipe 3.
