Description

Technical Field

[0001] The present application relates to the technical field of valve control, and in particular to a distributed ultrasonic water meter. Background Art

[0002] Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change in speed of the ultrasonic sound beam when it propagates downstream and upstream in water, analyzes and processes the water flow rate, and further calculates the water flow rate. It is widely popular due to its wide range ratio, high measurement accuracy and stable operation.

[0003] The existing ultrasonic water meter includes a detection tube, a sensor, a display screen and a water valve. The sensor is built into the detection tube along the length direction of the detection tube, and the water valve is set at one end of the water inlet of the detection tube to adjust the water flow rate flowing into the detection tube. When the water flows through the detection tube, the transmission time difference caused by the change in speed when the ultrasonic sound beam propagates in the water flow downstream and upstream is analyzed and processed to obtain the water flow rate, thereby further calculating the water flow rate, and displaying the water flow rate on the display screen, so that the meter reader can check the water flow rate of each ultrasonic water meter. At the same time, the user can also set the flow rate of the ultrasonic water meter according to his own needs. The ultrasonic water meter controls and adjusts the size of the water valve switch according to the water flow rate set by the user, so that the water flow rate of the water pipe meets the water flow rate set by the user.

[0004] With regard to the above-mentioned related technologies, the inventor believes that since the water valve and the ultrasonic water meter are an integrated structure and the water valve is a fragile component, once the water valve is damaged, the ultrasonic water meter needs to be completely disassembled for water valve maintenance, which causes the ultrasonic water meter to be unable to work normally for a certain period of time, thereby resulting in the defect of high water valve maintenance cost.
