Has the antifreeze technology of smart water meters improved?

Whether it is a smart water meter or a mechanical water meter, if it is installed outdoors, it is easy to freeze in winter. A common problem is that the glass of the water meter is bursting, because there is water in the dial of the water meter, which is expanded by cold. The other is that the temperature is extremely low, and the technical gears in the table are bursting.

Problem 1 Solution:

1. Magnetic transmission dry base meter, this kind of water meter dial does not go water, and is not affected by low temperature.

2. Insulation materials (glass fiber cloth, cotton and linen fabrics, plastic foam, straw rope, etc.) can be used to wrap and wrap tightly, and the water supply facilities in the shade should be thickened and tied.

Problem 2 Solution:

In addition to thermal insulation measures, keeping the water in the pipes flowing as much as possible can reduce the possibility of freezing the water meter.

Therefore, in the northern region where the incidence of water meter freeze is high, it is more recommended to use a dry radio frequency card water meter.

Ordinary dry water meters are not anti-freezing, liquid-sealed water meters are not anti-freezing, not to mention wet ones, the cold current at the beginning of 2016 froze a lot of ordinary dry water meters, and smart water meters are not spared. At present, only the patented product Taili anti-freezing water meter is a real anti-freezing water meter, and Taili anti-freezing water meter does not freeze or leak. Other introductions to what additional insulation materials are inefficient, needless to increase the cost of a very large amount, a huge waste of people, money and materials.

At present, there is no antifreeze water meter. It is recommended to use a dry water meter, which is not easy to freeze and break.

Now there are products specifically for water meters to do anti-freeze, you can search Dacheng County Tianlei fireproof material factory for consultation. The 20mm thick EVA polyethylene foam sponge material is highly used in the three northeastern provinces. Now it's about to spread across the country.

At the same time, in the days when the temperature is the lowest, keep the tap water at home running slowly, you can use a basin or something to connect the water, drop by drop of slow water, can also make the water meter not easy to freeze.

1. Use the electric heating bag of the water meter to keep the water meter warm. The electric heating bag of the water meter is heated by a voltage of 220v, so it can be used to wrap the water meter to protect the water meter from freezing.

2. Bury the water meter in visible soil. The surface temperature is still warmer than the air in winter, so you can bury the water meter in the soil that can be loosened, and it will be fine.

3. See if the water meter can be installed indoors. Water meters are usually installed outdoors, but if they are exposed to cold in winter, the meter will be severely damaged.

4. The water will generally not freeze when flowing in the water pipe, so that the water pipe is not frozen, the user can turn on the faucet before going to sleep at night, so that the fine water can flow for a long time, and it can generally be avoided by freezing when the temperature is low in the morning.

If you are not afraid of wasting water, turn on a small faucet in winter to let the water flow, which is simple and effective.

The upstairs method is also possible, but the antifreeze water meter has a dry water meter and a wet water meter. Dry water meter and wet water meter at the same height, wet water meter glass is easy to break, dry water meter has no water in it, table glass is not easy to break, in addition to the use of anti-freeze protection box, can be used with different insulation measures such as: high-density materials, insulation cotton, meter box cover to take protective measures, anti-freeze electric belt is through the power supply of 220.

It is advisable to bury the water meter in the ground and cover it with perlite or sawdust.

There are antifreeze protection boxes with different insulation medium materials, such as pure base paper foam, to form anti-freezing measures around the table and the meter box; Or use an electric heating bag to heat the meter through a 220V power supply, so as to achieve the anti-freezing effect. Water supply enterprises in the north (north of the Yangtze River) stipulate that the water meters installed outdoors are generally below the frozen soil, and indoor heating can ensure that the water meters are protected from freezing and cracking, and the situation is better than in the south.

Safety of water meter installation:

1. Before installing the water meter on the newly laid pipeline, the debris in the pipeline must be rinsed before installation, so as not to damage the water meter or affect the normal operation of the water meter after the water is opened;

2. When the water meter is installed, it must be considered that the water pressure and water temperature used on site are within the maximum pressure and maximum temperature of the water meter. When installing small-caliber civil water meters, attention should also be paid to whether the connection pipes and pipe joints of the following water meters feel particularly thin, so as to avoid installing fake and shoddy water meters;

3. The outdoor installation of water meters should generally be installed with a protective box, which should not be installed in exposed and frozen places to prevent external injuries. In the severe winter season, the water meter installed outdoors should have anti-freezing measures;

4. The location of the water meter should also avoid the erosion of corrosive gas;

5. If the industrial water meter is installed near the boiler, a check valve should be installed behind the meter to prevent the hot water from pouring back and damaging the water meter parts.

Hello: First, from the perspective of the structure of the water meter, it is divided into wet and dry; The glass of the wet water meter freezes and cracks; Whereas the dry water meter movement has no water, in the same case freeze protection;

2. Anti-freezing facilities for water meters: there are different insulation medium materials for anti-freeze protection boxes; Such as: pure base paper foam, the table and the meter box around the formation of anti-freezing measures; Depending on the region, there are different protective measures;

Three: electric heating bag, through 220V power supply, heat to protect the meter, so as to achieve the anti-freezing effect;

Four: Installed in the anti-freezing well, installed in the meter-deep backwater well to solve the problem of anti-freezing in winter;

Hope it helps.

1 The basic insulation measures are in place Wrap the insulation material for insulation treatment 2. The water meter will not be east if the water is not stopped.

Generally, it really can't be prevented, so it's better to try the layer of foam that wraps the hot water pipe.

There are several ways to protect the smart waterproof water meter in winter:

1. Sprinkle cold coal ash, sawdust, etc. on the water meter, use old cotton wool or other warm things, wrap the water meter, and wrap the water meter to facilitate the meter reader to check the meter.

2. When the temperature is low at night, close the ball valve in front of the water meter, and then empty the remaining water in the pipe behind the meter.

3. For users who are difficult to close the ball valve, they can use the trickle method: open the faucet to the minimum, and it is advisable for the water meter to just start rotating. This approach to the problem is not advocated because it is too wasteful of water.

The anti-freezing measures for water meters are:

1. Thoroughly clean and repair the inside of the water meter well. The water meter well is tight and free of stagnant water. The water supply facilities in the meter well should be intact and free of leaks.

2. Make a cold-proof mat of the same size as the water meter well. Choose plastic snakeskin bags, straw bags, filled with dry straw or homemade cotton pads, put them in the table well and cover them flat, or you can buy asphalt glass wool felt, which is both cold and moisture-proof.

3. Fill the water meter well without stagnant water with hay, slag, sawdust and other materials to the water meter base to protect the water meter and the pipes in the meter well.

4. Make a box with a thin wooden board and put it on the water meter, with a certain gap between the water meter and the wooden box, containing warm materials such as sawdust and rice husk asphalt glass, and the pipes at both ends of the water meter are wrapped with asphalt glass felt and linen.

The only real antifreeze water meter in the country.

You have a good mess type, there is only an anti-freezing water meter at present, and there is no need to conduct research on anti-freezing water meters. Because after the water meter freezes, the user cannot use water, and the measurement of the water meter is not accurate when it is a few degrees below zero. The best measure is to install an antifreeze layer on the water meters and water supply pipes to avoid freezing and cracking.

The user's water meter is transferred from the indoor to the outdoor centralized water meter box, and the wet bright water meter may freeze when the outdoor temperature drops to about 0.

After practical comparison, there are currently 3 schemes:

Scheme 1: Deepen the burial depth of the main car of the water meter, so that the geothermal heat can be relied on to protect the water meter, but the meter reading is inconvenient and the cost is high.

Scheme 2: Use a customized foam shell to cover the water meter, which can effectively play a role in heat preservation and reduce the cost, but it is inconvenient to read the meter. Moreover, the customized size of the foam is difficult to match the site.

Scheme 3: Fill the water meter box with yellow sand, which can have a good thermal insulation effect and greatly reduce costs. Scheme 3: It is a more economical and practical method to fill the hail yellow sand in the water meter box, and fill the yellow sand in the meter box to the copper edge of the water meter, so that the cold insulation effect is obvious.
