Description

Technical Field

[0001] The utility model relates to a multifunctional pipe section structure of an ultrasonic water meter, in particular to a multifunctional pipe section of an ultrasonic water meter equipped with multiple sensors, belonging to the technical field of ultrasonic flow measurement. Technical Background

[0002] As a new type of flow meter, ultrasonic water meters are gradually gaining widespread application due to their advantages such as high precision, no mechanical wear, and low pressure loss. However, existing small-diameter ultrasonic water meter pipe sections have relatively simple functions. In some complex measurement environments or when more fluid parameter information is needed to improve measurement accuracy, these single-function pipe sections cannot meet the measurement requirements. For example, temperature and pressure have a significant impact on the measurement accuracy of ultrasonic water meters. These factors often require additional devices and complex installation connections. The lack of an integrated measurement solution not only increases costs and complicates installation, but may also affect measurement accuracy and stability. Based on the above issues, there is an urgent need for a multifunctional pipe section that is low in cost, easy to install, and has comprehensive functions. Utility Model Content

[0004] The technical solution of the utility model is:

[0005] A multifunctional pipe section structure for an ultrasonic water meter comprises a copper pipe section, wherein a boss is provided on the pipe wall of the copper pipe section, and an upstream transducer hole, a pressure sensor hole, a downstream transducer hole, a temperature sensor hole and a valve stem hole are provided on the boss in sequence according to the direction of water flow; the upstream transducer hole, the pressure sensor hole, the downstream transducer hole and the temperature sensor hole are all arranged on a plane of the boss; an upstream transducer is installed in the upstream transducer hole and is pressed and fixed by a second pressure plate; a pressure sensor is installed in the pressure sensor hole; a downstream transducer is installed in the downstream transducer hole, and a temperature sensor is installed in the temperature sensor hole, and the downstream transducer and the temperature sensor are both pressed and fixed by a first pressure plate.

[0006] Furthermore, the plane position of the valve stem hole on the boss is higher than the plane positions of the upstream transducer hole, the pressure sensor hole, the downstream transducer hole and the temperature sensor hole.

[0007] Furthermore, the pressure plate 1 is a component for fixing the temperature sensor and the downstream transducer, and a screw hole is opened on the top. After the temperature sensor and the downstream transducer are respectively placed in the temperature sensor hole and the downstream transducer hole, the pressure plate 1 is placed on it and the screws are driven in to fix it to prevent the temperature sensor and the downstream transducer from falling off from the temperature sensor hole and the downstream transducer hole.

[0008] Furthermore, the second pressing plate is a component for fixing the upstream transducer, and is installed in the same manner as the first pressing plate to prevent the upstream transducer from falling off from the upstream transducer hole.

Real-time measurement of parameters such as temperature and pressure is used as an auxiliary function. In some complex measurement environments or when more fluid parameter information needs to be obtained, no additional devices and complex installation connections are required, thus saving costs; the integrated measurement mode can improve measurement accuracy; the sensor and transducer are fixed using a pressure plate structure, which is easy to install and reduces costs.

DETAILED DESCRIPTION

[0014] The present invention will be further described below through embodiments with reference to the accompanying drawings.

[0015] Combined with attachment Figure 1-3 A multifunctional pipe section structure for an ultrasonic water meter comprises a copper pipe section 1, a boss 17 being provided on the pipe wall of the copper pipe section 1, and an upstream transducer hole 11, a pressure sensor hole 13, a downstream transducer hole 12, a temperature sensor hole 10 and a valve stem hole 14 being provided on the boss 17 in sequence according to the direction of water flow; the upstream transducer hole 11, the pressure sensor hole 13, the downstream transducer hole 12 and the temperature sensor hole 10 are all arranged on a plane of the boss 17; an upstream transducer 4 is installed in the upstream transducer hole 11 and is pressed and fixed by a second pressing plate 16; a pressure sensor 3 is installed in the pressure sensor hole 13; a downstream transducer 5 is installed in the downstream transducer hole 12, and a temperature sensor 2 is installed in the temperature sensor hole 10, and the downstream transducer 5 and the temperature sensor 2 are both pressed and fixed by a first pressing plate 7.

[0016] Refer to the attached Figure 1The plane position of the valve stem hole 14 on the boss 17 is higher than the plane positions of the upstream transducer hole 11, the pressure sensor hole 13, the downstream transducer hole 12 and the temperature sensor hole 10.

[0017] The temperature sensor 2 is an important device for ultrasonic water meters to measure fluid temperature changes in real time. Its structure and size are adapted to the temperature sensor hole 10. To prevent fluid leakage, a sealing ring is added to the temperature sensor hole. The temperature sensor 2 comes into contact with the fluid after passing through the sealing ring and the mounting hole to measure the fluid temperature changes in real time.

[0018] The pressure sensor 3 is an important device for ultrasonic water meters to measure fluid pressure changes in real time. Its structure is divided into two parts, the upper and lower parts. The size of the lower end is adapted to the pressure sensor hole 13. After being inserted into the pressure sensor hole 13, it comes into contact with the fluid and measures the fluid pressure changes in real time.

[0019] The upstream transducer 4 and the downstream transducer 5 are important devices for ultrasonic water meters to measure fluid flow rate and flow rate. The upstream transducer 4 and the downstream transducer 5 are both composed of a transducer body and a signal line. The transducer body is cylindrical in shape, and its size and structure are adapted to the transducer hole. After being inserted into the upstream transducer hole 11 and the downstream transducer hole 12 respectively, they receive the corresponding upstream reflector 8 and downstream reflector 9 signals, and the software converts the received electrical signals into digital signals of the fluid flow rate.

[0020] The valve stem 6 is used to control the rotation of the valve core 15. The valve core 15 is cylindrical in shape and has a through hole in the middle to connect the valve stem 6. The valve stem 6 enters the valve core through hole from the valve stem hole 14. The size of the valve core 15 is the same as the inner diameter of the pipe section. The valve core 15 rotates from 0° to 90° with the valve stem 6. The state of the channel of the pipe section 1 changes from open to closed as the valve core 15 rotates.

[0021] The pressure plate 1 7 is a component for fixing the temperature sensor 2 and the downstream transducer 5. A screw hole is provided on the top. After the temperature sensor 2 and the downstream transducer 5 are respectively placed in the temperature sensor hole 10 and the downstream transducer hole 12, the pressure plate 1 7 is placed on it and screws are driven in to fix them to prevent the temperature sensor 2 and the downstream transducer 5 from falling off from the temperature sensor hole 10 and the downstream transducer hole 12.

[0022] The second pressing plate 16 is a component for fixing the upstream transducer 4 and is installed in the same manner as the first pressing plate 7 to prevent the upstream transducer 4 from falling off from the upstream transducer hole 11.

[0023] The upstream reflector 8 and the downstream reflector 9 correspond to the upstream transducer 4 and the downstream transducer 5 respectively. The planes of the upstream reflector 8 and the downstream reflector 9 for reflecting signals form a certain angle with the planes of the upstream transducer 4 and the downstream transducer 5 for receiving signals. The distance between the upstream reflector 8 and the downstream reflector 9 is the same as the distance between the upstream transducer 4 and the downstream transducer 5.
