Flow divider for district metering area (DMA) of water supplying pipe network

Abstract

The invention discloses a flow divider for a district metering area (DMA) of a water supplying pipe network, and belongs to the technical field of flow dividing of water supplying pipe networks. The flow divider aims at solving the problems that flow dividing design and flow metering design of an existing water supplying pipeline are constructed respectively, the construction difficulty is high, and the consistent metering time cannot be ensured. According to the flow divider, ultrasonic transducers are arranged on the walls of branch pipelines of an n-passage flow dividing pipe body, every two ultrasonic transducers are located on the two sides of the corresponding branch pipeline, the included acute angle between each ultrasonic transducer and the wall of the corresponding branch pipeline is 45 degrees, and the axes of every two ultrasonic transducers coincide with each other and intersect with the axis of the corresponding branch pipeline; a control box is used for forwards controlling the forward transmitting transducer on each branch pipeline to transmit signals, forwards controlling the reverse transmitting transducer on each branch pipeline to receive the signals, then reversely controlling the reverse transmitting transducer on each branch pipeline to transmit signals and reversely controlling the forward transmitting transducer on each branch pipeline to receive the signals; and finally, the liquid flow, corresponding to the intermediate time, in each branch pipeline is calculated. The flow divider is used for flow metering of the water supplying pipe network.

Description

technical field [0001] The invention relates to a diverter for independent metering partitions of a water supply pipe network, and belongs to the technical field of water supply pipe network diversion. Background technique [0002] With the acceleration of urbanization, the water demand of residents is increasing; in order to ensure the water consumption of users, higher requirements are put forward for the smooth operation of the water supply network. Among them, the leakage control of water supply pipe network, as the main problem of pipe network operation, has been paid more and more attention by the water affairs department. [0003] In the existing pipeline network leakage control methods, the method of independent metering area (DMA) has been widely used. DMA divides a large and complex pipe network system into several small and simple independent areas by dividing the whole into parts, and measures the amount of water diverted into or out of the independent areas by ...

AI Technical Summary

Problems solved by technology

[0007] In view of the problem that the diversion design and flow metering design of the existing water supply pipelines are constructed separately, and the construction is difficult when metering facilities need to be installed later; and each metering design is independent, and the metering time of the metering data cannot be guaranteed to be consistent. The present invention provides a Splitter for independent metering partition of water supply pipe network
