Tips for antifreeze and thermal insulation of water pipes in winter

1. How to prevent water pipes from freezing in winter? What are the anti-freezing skills of water pipes?

Anti-freezing skills of water pipes:

1, water pipes, water meters, faucets and other water facilities in residents' homes can be tightly wrapped with thermal insulation materials (glass fiber cloth, cotton and linen fabric, plastic foam, straw rope, etc.). ), and the water supply facilities in the shade should be thickened and tied. Indoor water meters can also use the antifreeze cover of water meters.

2. Close the windows of corridors, kitchens, toilets and all shady rooms at night to ensure that the indoor temperature is above zero degrees Celsius. At the same time, close the indoor water meter valve, turn on the faucet, and let off the remaining water in the water pipe.

3. In cold weather (below minus 3℃), after using water at night, slightly unscrew the faucet to keep the faucet dripping, so as to ensure the running water in the water pipe and prevent it from freezing at night.

4. For the roof water tank, the top cover of the water tank should be covered, and the upper and lower water inlet pipes and valves of the water tank should be tightly wrapped with thermal insulation materials. For outdoor installed water pipes, water pipes and valves can be wrapped with warm goods (such as cotton, cotton cloth, linen, straw belts, straw ropes, etc.). ). The plastic wrap should be kept dry, waterless and tightly wrapped, and then wrapped in plastic bags (films) or plastic tapes.

2. How to keep the water pipes warm in winter?

Some tropical and subtropical flowers prefer warmth to coldness. When the temperature drops to 0℃, they will suffer from freezing injury. Therefore, if you want to raise these flowers well, you must do a good job of cold protection and heat preservation in winter, so that they can spend the winter safely. Do it yourself, you can make simple equipment such as heat preservation and cold protection shed.

(1) Simple incubator. Self-made simple incubator, put a few pots of flowers, which can not only keep warm and moisturize, but also take up no space. The manufacturing method is as follows: firstly, make a box basket with a height of 160cm, a width of 80cm and a thickness of 50cm with hardwood strips or angle irons, then weave two netted trays with thick iron wires and put them in the basket, put flower pots on the trays respectively, put a small basin at the bottom of the box and install two incandescent bulbs of 40-60w, and finally cover the box with plastic film, which will not be used indoors. The incubator can not only keep moisture, but also increase temperature and light, which is very beneficial to the safe overwintering and sustainable growth of flowers that like high temperature and high humidity.

(2) Plastic shed. Set up a bamboo bow shed at Nanyang Terrace. The requirement of the shed is low in the front and high in the back. The top and periphery are covered with double plastic films, and the bottom is pressed with bricks. When it is cold, cover it with a straw curtain or an old blanket at night to keep warm. After winter, low-temperature tolerant flowers and trees such as Chinese rose, pomegranate, oleander, peony, osmanthus, kumquat and conifer can be put into the shed for the winter.

(3) The indoor greenhouse in front of the window. Make a rectangular wooden (iron) basket about 140 cm long, 30 cm wide and 70 cm high, and wrap it tightly with plastic film. Install the greenhouse basket on the window facing south, and the base is flush with the top of the heater. After putting in the flowerpot, clamp the door curtain with a clothes peg. And pay attention to the following points: ① Water for watering flowers needs water close to room temperature, and cold water cannot be used. (2) Wash the dust outside the plastic film with clear water frequently to facilitate the lighting of flowers. (3) often sprinkle water on the ground to increase air humidity. (4) Water should be dry and wet, and it is advisable to dry it slightly.

3. How to prevent water pipes from freezing and keep warm?

Daily water use is related to the quality of life of every resident, so we need to know all kinds of methods to prevent water pipes from freezing in life, so as to provide convenience for future water use.

Therefore, it is necessary to understand the anti-freezing measures of water pipes in winter. The following is the introduction of anti-freezing measures for water pipes in winter, hoping to help everyone. Anti-freezing method of water pipes: 1. In the north where the temperature is underground, you can wrap a layer of cotton and linen to keep warm when the water pipe is antifreeze. You can wrap the hose beautifully. Interested owners can also doodle on the water pipes, which can beautify the effect and protect the water pipes well.

Water pipe antifreeze method: 2. If the indoor temperature is increased in winter, the indoor temperature will be lower. If the doors and windows are not closed at night, the indoor temperature will be lower, so even the indoor water pipes will freeze. Therefore, if you want to prevent indoor water pipes from freezing in winter, you can raise the indoor temperature, turn on some heating properly, or choose thicker curtains.

Water pipe antifreeze method: 3. We all know that flowing water is not easy to freeze, so the best way to prevent water pipes from freezing is to keep the water flowing. Although this method can prevent water pipes from freezing, it will waste some water resources. Water pipe antifreeze method: 4. Drain the remaining water from the water pipe. Because some of the above methods will cause waste of water resources, here Poly Pipeline introduces another method, that is, pull down the sluice at home in winter, and then let the water out of the water pipe so that it will not overflow, but remember to pay attention to the sluice to keep warm.

In addition to the above methods, there are also popular electric heating insulation bags, which are widely used in solar water heaters. If it is used in the insulation and heating of tap water pipes, it is feasible and the price is slightly expensive. Be careful not to pour hot water directly on the frozen water pipe, which may easily cause the water pipe to rupture; If the outdoor tap water pipeline is broken, please close the water meter valve to stop the water supply; If not, the damaged part can be tied with cloth for emergency treatment, and then contact a professional water supply enterprise for treatment; Citizens and friends should prepare for water storage at night, and it is best to prepare hot water to avoid the inconvenience caused by life the next day.

4. Common sense: Teach you how to prevent water pipe faucet from freezing.

According to past experience, the freezing weather of rain, snow, strong wind will have a great impact on urban traffic, water supply and power supply. Nanchang water supply department has issued anti-freezing tips for water supply facilities.

Nanchang water supply department reminds the general public to make timely preparations to avoid freezing of outdoor water pipes and water meters caused by sudden drop in temperature, which will affect normal water use. Users who install pipelines in the north and windward side should pay special attention. In addition, galvanized iron pipes are easier to freeze than hot melt pipes, and should be fully insulated and bandaged. At the same time, the water supply department reminds all owners, property management companies and residents to do a good job of anti-freezing and heat preservation of water facilities such as residential pipelines, building risers and roof water tanks in advance.

For the water meter installed outdoors, you can choose a thick towel or cloth to wrap the water meter, or you can turn on the faucet at home to let the water flow out in a linear way and let the water in the water pipe move, so as to prevent the water meter and water pipe from freezing. If the water meter has frozen, wrap it with a hot towel and sprinkle it with warm water (not exceeding 60 degrees Celsius) until the ice in the pipe melts and the water flows out smoothly. Do not pour boiling water or bake with fire to avoid damaging the plastic parts in the water meter.

Outdoor exposed water pipes and indoor water pipes can be wrapped with thermal insulation materials (such as old clothes, cotton wool, sponge, etc.). ), and a layer of waterproof material (plastic sheets, etc.). ) wrapped in insulation materials to prevent them from freezing. If the faucet and water pipe are frozen, you can blow them with a hair dryer, or wrap them in a towel and slowly pour in warm water. At the same time, you can tap the water pipe gently with a hard object until the ice in the pipe melts and the tap water flows out smoothly.

5. How to prevent household tap water from freezing in winter?

1, put a coat on the water supply pipe.

In the north where the temperature is underground, you can wrap a layer of cotton and linen around the water pipe to keep warm when the water pipe is antifreeze. You can wrap the water pipe beautifully when you wrap it. Interested owners can also doodle on the water pipes, which can beautify the effect and protect the water pipes.

2, improve the indoor temperature

The indoor temperature is also relatively low in winter. If the doors and windows are not closed at night, the indoor temperature will be lower, so even the indoor water pipes will freeze. Therefore, if you want to prevent indoor water pipes from freezing in winter, you can raise the indoor temperature, turn on some heating properly, or choose thicker curtains.

3. Drop antifreeze

Flowing water is not easy to freeze, so the best way to prevent water pipes from freezing is to keep the water flowing. Although this method can prevent water pipes from freezing, it will waste some water resources.

4. Drain the residual water in the water pipe.

Because some of the above methods will waste water resources, here is another method, that is, pull down the sluice at home in winter, and then drain the water in the water pipe, so that the water in the water pipe will not overflow, but remember to keep the sluice warm.

Disinfection method of tap water:

At present, most tap water is chlorinated. The main purpose of chlorination of public water supply is to prevent water-borne diseases. This method has been popularized for more than 100 years, and it has relatively perfect production technology and equipment. Chlorine used for disinfection of tap water has the advantages of good disinfection effect, low cost and almost no harmful substances.

However, after understanding and studying the theoretical data, it is found that chlorine still has some disadvantages in disinfection of tap water. Chlorinated tap water will produce carcinogens. At present, relevant experts have put forward many improvement measures.

Chlorine is dissolved in water and reacts with water to produce hypochlorous acid and hydrochloric acid, and hypochlorous acid plays a major role in the whole disinfection process. For inorganic substances with peculiar smell, they can be thoroughly oxidized and disinfected. For algae, bacteria and other living natural substances, they can penetrate the cell wall, oxidize their enzyme systems (enzymes are biocatalysts), inactivate them, hinder the life activities of bacteria and die.

Hypochloric acid itself is close to neutrality, easy to approach bacteria, showing good bactericidal effect. Hypochlorite ion also has a certain disinfection effect, but it is difficult to get close to negatively charged bacteria (negatively charged bacteria), so its disinfection effect is much worse than hypochlorous acid, so chlorine disinfection effect is better than bleaching powder disinfection.
