Teach you how to rule out the rotation of the water meter

[Chinese instrument network encyclopedia knowledge] winter has come, not only people become tired, even the water meter has become wayward. In winter, there will be a phenomenon that the water meter does not use the water meter, which is called water meter rotation. The following is a summary of the maintenance staff of Shandong Jinan Water Supply Group, and teach yourself to eliminate the phenomenon of water meter rotation.

One of the reasons is that the water in the room has leakage.

There are many types of household water appliances, and if there is leakage, users can find and repair it in time. However, leakage of toilet water storage tanks in household water appliances is not easy to find, which can easily cause the rotation of the water meter. There are two major leaks in the water storage tanks: First, the float tank floats are adjusted too high or fail, causing tap water to overflow from the tank overflow port. Outflow causes the water meter to turn. The solution is to lower the float position or replace the defective part. The second is that the aging of the water outlet of the water storage tank or the opening of the water stop can cause the water meter to rotate. When the amount of water leakage is large, it may appear to follow the leakage phenomenon. The water meter pointer rotates evenly and smoothly; when the water leakage is small, intermittent performance may occur. Make up the water, make the water meter stop when the time, the interval time is a few minutes to ten minutes. The solution is to replace the damaged part.

The second reason: Old-fashioned valve pad damage Old-fashioned valves are mostly spiral open methods that require 720° to fully open. New valves can be opened by just 90°. When the user of the same pipeline finishes using water, the old valve is closed. The pressure is several times that of the new valve. When the old valve pad is damaged and the leakage is very inconspicuous, the water meter pointer does not move. When other users on the same pipeline run out of water and close the valve, the water pressure increases, causing tap water to flow from the damage of the old valve pad. To make the water meter turn. The solution is to replace the damaged part.

The third reason: water leakage in the indoor water supply pipeline.

When water leakage occurs in the general indoor water supply pipeline, the user can easily find out, just look for the property or property company for maintenance, or call “Xiao Bai Hotline 82612319” Jinan Water to provide you with the service of the customer table. Some users of the first floor buried the indoor water supply pipeline underground in the renovation. When this water supply pipeline leaks, the water will leak directly to the ground. The user cannot find it in time, but the water meter pointer turns evenly and smoothly. The simple way to judge is to turn off all the water equipment. If there is no other water equipment leaking, check whether the water meter pointer rotates evenly and smoothly. If there is any movement, there is water leakage in the water supply pipeline.

The fourth reason is that there are gas in the water supply pipeline to form water hammer.

The presence of gas in the water supply pipeline is another reason for the rotation of the water meter. When there is air in the water pipe, because the water is physically incompressible, and the air can be compressed, when the user turns off the water tap, the inertia pressure in the water pipe increases instantaneously, the air in the water pipe is compressed, and then rebounds. The water in the water pipe flows back and forth. Due to the pressure change in the water pipe, the “walking” of the water meter may also cause the water meter to “reverse”. These fluctuations are all within the error range of the water meter. Overall, the user’s profit and loss are basically the same, and the people will not be as numerous. Water fee. There are many reasons for the intake of pipelines. One is that the water supply pipeline has air due to the unreasonable design of the new water-passing residences, indoor pipelines, and unauthorized conversion of users' pipelines. The solution is to close the home water main valve, open all the faucets and plugs in the house, and then open the main water valve to discharge water for 1-2 minutes to exhaust. The second is that under the effect of water pressure, water will also be pressed into some water appliances that will have space or be deformed after being pressurized, such as water tanks for water heaters, water tanks for toilets, washing machines, and water heaters. Water hoses and so on. The solution is to install a cut-out door in front of these water appliances and close it when not in use. At the same time, it is recommended that when the user is not at home for a long time, the total water valve in the room should be closed.

How do leaks in the home self-checking method and treatment method know whether the water pipe (dark pipe) in the home leaks? Tell you the simplest way to check: Close all the taps in your home and observe the total water meter on the incoming water pipe for 1-2 minutes to see if the water meter has a continuous and continuous rotation. If yes, it can be judged as leaking (or leaking at home) after the watch.

Approach:

1. Check whether the toilet in the home is stuck or damaged. Replace the toilet.

2, please professional leak detection company leak detection. Repair the leakage point after repairing.

In order to do a good job of anti-freezing work for the winter tap water meter, please protect the tap water meter box or wall-mounted water meter box from frost. The Municipal Public Utilities Water Group reminds the public:

1, outdoor exposed pipes and faucets, etc., must be wrapped with cotton, linen fabric, plastic foam and other thermal insulation materials, do well insulation. Old cotton wool, straw mats and other warm items can be used to cover the water supply facilities in the water meter well (water meter box). After the snow is cleared, the snow on the surface of the water meter well shall be removed in time to prevent the snow from flowing into the meter well after melting.

2. Whenever you are away for more than two days, please close the tap water valve after the water meter, empty the pipeline and water equipment, such as tap water in the solar energy, to prevent the water pipe from freezing or freezing, causing water leakage and inundation, which will bring unnecessary to your life. loss.

3. Newly built residential units with low occupancy rate and unoccupied water users, especially in December, January and February when the weather is coldest. If there is no living, please apply for water stoppage procedures in time; The valve drains the remaining water in the pipe.

4. When replacing the insulation material in the water meter well, first check whether the bottom of the water meter and the water pipe are solid. After confirmation, use a snake skin bag or other Packaging Bag to install the insulation material. Do not tie it tightly, fill in the solid water well, and read the meter. When the bag is removed, it is convenient for meter reading and keeping the well clean.

5, indoor water supply facilities are generally exposed, under normal circumstances, please bare water pipes, water meters wrapped in a layer of cotton fabric insulation; close the doors and windows before going to sleep, try to increase the indoor temperature.

6. The windows of the kitchen, toilets and all shade rooms should be closed at night to ensure that the indoor temperature is above zero degrees Celsius.

7. When the temperature drops to minus 5 degrees Celsius, it is best to unscrew the faucet to make the water in the pipe flow to prevent freezing after the water is used in the evening.

8, outdoor water pipes such as balconies should pay attention to insulation, prevent the freezing of water pipes affect indoor water use.

9. In case of water stoppage, prepare for water storage at night, preferably hot water, so as to avoid inconvenience to the morning of the next morning. For pipes that are frozen, they can be blow-dried by using a hair dryer, or wrapped in a towel and slowly poured with warm water. Do not use fire to bake or use water to freeze.

Water pipe anti-freeze methods ● Wrap cold-proof materials Use blankets, cloth strips, ropes, felt, and other items to wrap water pipes and faucets. It would be better to wrap a layer of plastic cloth on the outside.

● Anti-frozen water meter can be filled in the water meter well old blankets, rags, waste paper and other items, surface mounted water meters can be wrapped with cold materials.

● Thaw the pipes Do not pour hot water directly on the frozen pipes. This may cause pipes to crack. Apply a towel, a rag to the water pipe, then slowly pour it in the warm water from the tap.

● When the indoor water pipe breaks when the water pipe bursts, turn off the water meter valve to stop the water. If the valve has been unable to close, use a piece of cloth to tie the ruptured part firmly and carry out emergency treatment, and then promptly report for repair.
