Device for measuring leakage of water supply pipeline in laboratory and measuring method using same

Abstract

The invention relates to a device for measuring leakage of a water supply pipeline and a measuring method using the device, in particular to a device for measuring leakage of a water supply pipeline in a laboratory and a measuring method using the device. The device for measuring leakage of the water supply pipeline in the laboratory and the measuring method using the device are used for solving the problems that in the prior art, a method for detecting the relation between the leakage amount and the pressure of a water supply pipeline cannot achieve the purpose of measuring the leakage amount of leaking openings with different shapes, or when a nighttime minimum flow method is used for measurement by collecting regional pipe network data, the method is complex and high in time consumption, and regional normal water supply is influenced. The device is composed of a controllable valve, a tail end pressure gauge, a vent valve, a casing pipe, a front-end pressure gauge, the water supply pipeline, a hoop, a volume flowmeter, a water containing device, a surge bank, a water pump, a water tank and a programmable logic controller. The measuring method comprises the steps of adjusting the water pressure and measuring the leakage amount. The device for measuring leakage of the water supply pipeline in the laboratory and the measuring method using the device are implemented.

Description

technical field [0001] The invention relates to a device for measuring the leakage of a water supply pipeline and a measuring method using the device. Background technique [0002] Due to pipeline corrosion, there are different forms of leaks on the water supply network, and leakage is prone to occur during the water distribution process. After the water is transported through the water supply network for a long distance, the water pressure of the pipe network will decrease, and the water supply will decrease. With the increase of leakage, In the end, the water pressure will be insufficient to meet the needs of users; the seriousness of leakage: due to corrosion of pipelines, loose joints of pipelines, and excessive operating pressure of pipelines in underground water supply pipe networks, the leakage of most urban pipe networks has reached the total More than 20% of the water supply, a serious waste of water resources. my country is a country with few per capita water reso...
