Description

Plug-in electromagnetic water meter

Technical Field

The utility model relates to a water gauge count technical field, concretely relates to bayonet electromagnetism water gauge.

Background

On a tap water pipe network for trade settlement or flow monitoring, various metering water meters need to be installed, the most common is a mechanical impeller water meter, the occupied amount is the largest at present, and then a pipe section type ultrasonic water meter and a pipe section type electromagnetic water meter are installed. The conventional mechanical water meter is mainly used for a long time due to lower manufacturing cost, and because the internal impeller, the gear and other conversion parts are plastic parts, the abrasion resistance is limited, the water meter can be slowly worn for one or two years, so that loss is caused to water sellers, the impeller occupies most space of a pipeline, the water passing capacity is reduced, pressure loss is generated, the power consumption of a water pump of a pump station is increased, and the energy conservation and consumption reduction are not facilitated.

With the continuous development of electronic technology and the demand of users for wide-range non-pressure-loss water meters, the pipe-section type ultrasonic water meter and the pipe-section type electromagnetic water meter are produced. The two kinds of electronic water meters have no movable parts, can achieve the performance of large range ratio and almost zero pressure loss by measuring the flow rate of water in the straight-through pipeline, and in addition, the theoretical battery life of the two kinds of water meters is 6-8 years, so that the two kinds of electronic water meters do not need to be frequently disassembled and assembled, and manpower and material resources are saved. The two kinds of pipe-section type electronic water meters are favored by water supply companies and users as soon as the two kinds of pipe-section type electronic water meters appear, and particularly, the excellent small flow metering performance of the two kinds of pipe-section type electronic water meters is preferred in the flow monitoring requirement of a water supply network. However, in the practical use process, the pipe-section type ultrasonic water meter gradually exposes to two problems of transducer fatigue and transducer scaling, so that the water meter is slower after one or two years, and the long-term metering stability is questioned by water. The solution is to remove the scale or calibration for maintenance and also to require frequent water shut-down for assembly and disassembly. The pipe-section type electromagnetic water meter is good in long-term stability after years of practice on metering performance, scaling does not occur, and the requirement of a water department is basically met. But the country has hard regulations for reasons based on mechanical watches: all large-diameter water meter water meters larger than 100mm need to be detached for verification and calibration every two years, and the fairness of trade settlement is ensured.

In the prior art, the design life is short, or the maintenance is needed, the verification and calibration are needed in a period of 2 years, so that the water has to be frequently stopped for assembly and disassembly, the labor cost is high, and the production life of a user is seriously influenced. Because the users are schools of enterprises and public institutions, the population under the watch is huge, water is not easy to stop, and even the user needs to be examined and approved by a captain. If the water meter is a large water meter with the flow monitoring function of more than 500mm, the production and life of hundreds of thousands of people and even hundreds of thousands of people are almost impossible, and the economic loss of water after one stop can reach millions.
