Q:Galvanized plastic lined pipe water meter is usually installed in front of the valve, or in the valve after installation
After valve.Because the pipe position is not properly installed, it will cause the water meter to idle even if you are not using water
Q:What are the sizes of the water meters in general?
General household water meter caliber: 15mm, 20mm, 25mm, 32mm. 15mm and 20mm mostly, there are a small number of 25, 32 of water meters, water gauge caliber depends on the size of the installation of the pipe diameter, that is, usually 4 points, 6 in charge.
Q:What is the nominal flow of water meters?
Nominal flow is the maximum flow that a meter allows for long-term use, under rated operating conditions.
Q:Must the new water meter be checked before use? Does the state expressly provide for it? In which regulation do you specify clearly?
Water meters belong to measuring instruments, and should be adjusted by the People's Republic of China metrology law.
Q:Why can the high level intelligent water meter be equipped with a check valve that can not prevent the water meter from idling?
The air sac causes a greater amount of rotation in this case. Production process of tap water enterprises are open construction, in the production process of water dissolved gas, at the same time in the construction process, the pipeline will be brought into the gas pipeline, if the exhaust valve is unreasonable, gas cannot be ruled out well. Thus, if the house does not use water for a long time, or the pipe design is unreasonable, the highest point or the starting point of the pipe in the house will have an air sac. As we all know, the compressibility of gases is very high. At this time, if there is pressure fluctuation on the pipe network, the space expansion in the pipeline will be very large, so the water meter will rotate more. According to statistics, the resulting water is less than 2-3 m3/ months, and more will produce dozens of cubic meters of water per month. According to the report statistics, the existing users reflect the water meter rotation of the phone 26, after field investigation and treatment found that because of the table after the airbag inside the house and the rotation of 21 households, accounting for 80.8%, after the pipeline leaking 5. Therefore, at present, most of the water meter produces rotation phenomenon, all because the back of the tube in the air bag caused.
Q:The cause of the water meter's rotation
This causes the rotation of the airbag, large amount of water. Tap water production process enterprise is open construction, in the production process of water dissolved gas, at the same time in the construction process, the pipeline will be brought into the gas pipeline, if the exhaust valve is unreasonable, gas cannot be ruled out such well. If the family for a long time without water or pipeline design is not reasonable, the highest point in the home or pipeline will be produced. The airbag sudden starting point as everyone knows, the compressibility of the gas is very high, if the pipe network pressure fluctuations, after duct space expansion will be a great amount of water rotation resulting according to statistics, resulting in less water is 2-3 more than m3 months, there will be dozens of monthly cubic meters of water. According to statistics, the existing water meter rotation to reflect the users call 26, after the scene investigation found, Because there is an air bag in the pipe behind the table, there are 21 households that make the rotation, accounting for 80.8%. After the meter, the pipe leaks 5. Therefore, at present, most of the water meters produce the rotation phenomenon, all because the memory behind the tube is caused by the air bag
Q:Advantages of intelligent water meters
Water consumption can be recorded and displayed electronically;
Q:What are the technical specifications for the installation of water meters?
Selection of water meter diameter pipeline installation location not only consider the waist diameter, but also consider the size of the flow is often used to select the suitable caliber water meter, to often use traffic close to or less than the water flux is appropriate.
Q:How many parts does the water meter consist of?
The internal structure of the traditional water meter of the traditional water meter from the outside can be divided into shell, sleeve, inner core three pieces. The shell is cast iron, water from the water inlet out through the lower part of the annular space of the shell, it is called "annulus".
Q:What is the working principle of the code type pre paid water meter?
LCD query: press the query key, the user can learn from the LCD screen on their use (cumulative usage, purchase times, current margin, the latest amount of purchase).
