After reading so many articles about how to make a decoration budget, how to buy building materials, how to prevent increasing items, and so on, the article on decoration and money saving is enough? If you think that way, then I can only send you a famous saying "Tuttu is broken." There is one thing that people rarely notice, but many people in life will encounter it. It is the necessary water meter and electricity meter. If water meters and meters fail, your home's utility bills may grow like a house price. Therefore, if you want to save money, the meter problem must be taken seriously.

After the renovation is completed, the meter will not turn when you switch off your home switch. When you send all the other open airs and all the lights and sockets in the house are not used, the meter starts to rotate slowly. What is the reason?

Everyone should know that using a wire along the 10KV high voltage line about 2.5 meters, pull 200 meters you will know that this wire has electricity began to hemp, and simply said this is called induction, do not believe that your home longer lines You try out the insulating layer of the wire with an electric pencil, and the tube of the test pencil will be reddish. Therefore, the power meter will appear to rotate, which is also related to the circuit in your home. It is usually safe to turn off other circuits without using electricity. It is relatively safe. Inductive power can make the meter turn slightly. There is also a way to deal with it. It is to ground the 0 line. Eliminates induced electricity. The grounding point can be located in the toilet's equipotential grounding box.

In addition to the problems of electricity meters, there are cases where the smart water meter rotates. In the process of using smart water meters, we often find that there is no water in the home, but the smart water meter is still turning. In many cases, it is thought that the water supply unit deliberately got it. Actually, this phenomenon is very common in the use of water meters. This is mainly due to reasons such as the negligence of installation and the gas in the pipeline. Today, we look specifically at the causes of rotation and the methods and measures to prevent the rotation of smart water meters.

A lot of money is the rotation of the meter! The reason for the rotation of the meter and its solution:

1. Excluding the gas evolved in the pipeline

In the design, according to the characteristics of the pipeline, the exhaust valve should be arranged rationally to eliminate the gas precipitated in the pipeline. When the newly installed pipeline or the newly installed household water is turned on for the first time, the valve should be opened slowly to empty the air in the pipeline to reduce the water content. Gas volume.

2, indoor installation is not reasonable

The main reason for the phenomenon of self-rotation of smart water meters is due to indoor pipes and water appliances leaking. The main reason is that the installation of unreasonable indoor pipes leads to indoor air bags causing air bags, so it should be done in future work.

3、Install check valve before smart water meter

Since the smart water meter rotates due to pressure fluctuations and the water is compressed, consider installing a check valve that can stop the water from flowing back. In this way, when the pressure rises, the water is compressed and the smart meter rotates positively; when the pressure decreases, the check valve closes automatically and the smart water meter does not rotate. When the pressure rises again, as long as the pressure is not higher than the pressure in the check valve, the smart water meter will not turn again; the smart water meter rotates mainly because the smart water meter reciprocates many times before it accumulates a large amount of water, and the check valve can be installed. By reducing the frequency of rotation of the smart water meter, it is also possible to solve the problem of smart water meter rotation caused by pressure fluctuations. However, due to the high frequency of domestic water use by residents and the small fluctuations in pipeline pressure, the check valves are required to have high sensitivity and high quality requirements.

4, can install the exhaust valve

The main reason for the rotation of the smart water meter is still caused by gas, so consider installing an exhaust valve. However, due to the high price of exhaust valves and the high requirements for installation location, pipeline layout and check valve sensitivity, it will also add a certain amount of work to the maintenance and management of the pipeline network. Therefore, install exhaust valves as few as possible unless necessary. .
