Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to a drip-proof water meter. Background Technology

[0002] A water meter is an instrument used to measure water flow. Most of them measure the cumulative flow of water. They are generally divided into two categories: volumetric water meters and velocity water meters. Originating in the UK, water meters have been developed for nearly two hundred years. When selecting a water meter, you should first estimate the flow rate and range you usually use, and then choose the water meter with the closest commonly used flow rate as your first choice.

[0003] Existing water meters cannot measure water flow when the flow rate is low. In other words, when water is flowing through the water supply valve in a dripping manner, the water meter cannot measure the water consumption, resulting in water waste. In addition, water meters are usually installed and fixed using flanges, which require multiple bolts, making the installation process cumbersome. Therefore, a drip-proof water meter is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, water meters are usually installed and fixed using flanges, which requires multiple bolts and makes the installation process cumbersome. Therefore, this invention proposes a drip-proof water meter.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a drip-proof water meter, comprising a pipe body, a water meter body installed on the top of the pipe body, differential pressure sensors fixedly installed on the surface of the pipe body near both ends, L-shaped ring covers fitted and fixedly connected to the surface of the pipe body near both ends, L-shaped ring plates fitted and rotatably connected to the surface of the pipe body and inside the L-shaped ring covers, arc holes evenly spaced on one end surface of the L-shaped ring covers, arc plates embedded inside the arc holes, the outer arc edge of the L-shaped ring plate threadedly connected to the inner arc edge of the arc plate, a rotating ring fixedly connected to one end of the L-shaped ring plate, a fixed ring plate fixedly connected to one end of the arc plate, and a connecting pipe fixedly connected to the surface of the fixed ring plate.

[0006] Preferably, the surface of the rotating ring is provided with protrusions at equal intervals.

[0007] Preferably, the surface of the L-shaped ring plate is provided with a ring groove, and a compression ring plate is embedded inside the ring groove, and the compression ring plate is fixedly connected to the fixed ring plate.

[0008] Preferably, a sealing ring gasket is fixedly connected to the other end of the extrusion ring plate, and one side wall of the sealing ring gasket is in contact with the inner wall of the ring groove.

[0009] Preferably, the arc plate is adapted to the arc hole.

[0010] Preferably, the inner wall of the L-shaped ring plate and near its outer edge are fixedly connected with ring-shaped baffles.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by embedding the arc plate into the arc hole and threading the inner wall of the arc plate to the surface of the L-shaped ring plate, and then rotating the rotating ring to drive the L-shaped ring plate to rotate, the arc plate can be fully inserted into the arc hole. This allows the arc plate to drive the fixed ring plate to push the extrusion ring plate to extrude the sealing ring gasket, thereby improving the sealing performance of the pipe body and the connecting pipe, and also facilitating installation and disassembly.

[0013] 2. In this utility model, differential pressure sensors are installed on the surface of the pipe body near both ends. When water flows through, a pressure difference is generated between the inlet and outlet of the water meter. Under normal flow conditions, the pressure difference is within a certain range, and the water meter measures normally. In the event of a leak, a change in pressure difference will occur, and the change pattern will be different from that under normal flow conditions. The differential pressure sensor can sensitively detect this subtle change and can be used to determine whether there is a leak. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figure 1-5 As shown, this utility model provides a drip-proof water meter, including a pipe body 1. A water meter body 2 is installed on the top of the pipe body 1. Differential pressure sensors 3 are fixedly installed on the surface of the pipe body 1 near both ends, which can sense the pressure at both ends of the pipe body 1. An L-shaped ring cover 4 is sleeved and fixedly connected to the surface of the pipe body 1 near both ends. An L-shaped ring plate 5 is sleeved and rotatably connected to the surface of the pipe body 1 and inside the L-shaped ring cover 4. An arc hole 7 is evenly spaced on one end surface of the L-shaped ring cover 4. An arc plate 8 is embedded in the arc hole 7. The outer arc edge of the L-shaped ring plate 5 is threadedly connected to the inner arc edge of the arc plate 8. A rotating ring 6 is fixedly connected to one end of the L-shaped ring plate 5. A fixing ring plate 9 is fixedly connected to one end of the arc plate 8. A connecting pipe 10 is fixedly connected to the surface of the fixing ring plate 9, which can insert the arc plate 8 from the arc hole 7. At this time, the rotating ring 6 can drive the L-shaped ring plate 5 to rotate. The rotation of the L-shaped ring plate 5 can drive the arc plate 8 to move inward, thereby fixing the connecting pipe 10.

[0023] Example 2, as Figure 1-5 As shown, the rotating ring 6 has protrusions at equal intervals on its surface, which facilitates its rotation. The L-shaped ring plate 5 has an annular groove 11 on its surface, into which a compression ring plate 12 is embedded. The compression ring plate 12 is fixedly connected to the fixed ring plate 9, which positions the connecting pipe 10. A sealing ring gasket 13 is fixedly connected to the other end of the compression ring plate 12. One side wall of the sealing ring gasket 13 is in contact with the inner wall of the annular groove 11, allowing the compression ring plate 12 to compress the sealing ring gasket 13 for sealing. The arc plate 8 is adapted to the arc hole 7, allowing the arc plate 8 to be completely embedded inside the arc hole 7. Ring-shaped baffles 14 are fixedly connected to the inner wall of the L-shaped ring plate 5 and near its outer edge, which blocks the L-shaped ring plate 5.

[0024] Working principle: By embedding the arc plate 8 into the arc hole 7, and threading the inner wall of the arc plate 8 to the surface of the L-shaped ring plate 5, and then rotating the rotating ring 6 to drive the L-shaped ring plate 5 to rotate, the arc plate 8 can be fully inserted into the arc hole 7. This allows the arc plate 8 to drive the fixed ring plate 9 to push the squeezing ring plate 12 to squeeze the sealing ring gasket 13, thereby improving the sealing performance of the pipe body 1 and the connecting pipe 10. It also facilitates installation and disassembly. At this time, differential pressure sensors 3 are installed on the surface of the pipe body 1 and near both ends. When water flows through, a pressure difference will be generated at the inlet and outlet of the water meter. Under normal flow conditions, the pressure difference is within a certain range, and the water meter measures normally. In the case of leakage, the pressure difference will change, and the change pattern of the pressure difference under normal flow conditions will be different. The differential pressure sensor 3 can sensitively detect this subtle change and can be used to determine whether it is a dripping water flow.

[0025] The wiring diagrams of the water meter body 2 and the differential pressure sensor 3 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the water meter body 2 and the differential pressure sensor 3 will not be explained in detail.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
