Turn on the faucet

In severe cold winter, due to the low temperature, it is easy to freeze the water pipes. What about the anti-freezing application of water pipes? The following editor will provide you with some preventive measures to prevent freezing of water pipes. On nights when the temperature is very low in winter, you can turn on the faucet a little bit to let the water continue to flow out. The flowing water can effectively prevent the water pipes from freezing even in a colder environment. When turning on the faucet, you need to pay attention that only a small water flow is needed. If the water flow is too large, it will waste too much water, which is very uneconomical. Large diameter plastic coated steel pipe

The anti-freezing method of indoor water pipes is relatively simple in facility engineering, but the anti-freezing method of outdoor water pipes is more troublesome. When anti-freezing outdoor water pipes, you can wrap the faucet with cotton, hemp silk or straw rope, and also It is necessary to wrap the water pipe tightly with cotton or linen fabric or anti-freeze sleeve. It is best to wrap the water pipe in several layers, so as to effectively enhance the warmth of the water pipe and prevent the water pipe from being frozen. The pipes at both ends of the water meter and the exposed pipes exposed on the ground should also be wrapped with cotton fabric, and the water meter box should be kept dry and the cover should be tightly closed. After it snows, the snow on the water meter box should be removed in time to prevent the snow from melting and flowing into it. Inside the water meter box.

Temperature switch

When the temperature is low, you can also close the small indoor water meter valve before going to bed, and then turn on the faucet to drain the remaining water in the water pipe. This water pipe antifreeze method can effectively save water compared with the previous opening of the faucet. In the water pipe antifreeze, some material experts have designed materials that can sensitively sense temperature according to the principle of the thermal expansion and contraction characteristics of the material. A mechanical temperature-sensing switch was developed according to the shape change of special materials at different temperatures. It means that the switch will automatically open when the temperature is close to the freezing point, so that the cold water in the pipeline can be effectively discharged, and the valve will be automatically closed when the temperature is appropriate.

Heat up

The most important thing in the anti-freezing method of the water pipe is to ensure the temperature of the water pipe and avoid the temperature of the water pipe from being too low. This can effectively prevent the water pipe from freezing. If the water pipe has been frozen, you can wrap the faucet with a hot towel on the faucet, water pipe, and water meter that has been frozen, and then use warm water to thaw the tap water, but you must remember that the warm water should not be too hot. The most important thing in thawing is to control the water temperature, so that it can be effective and at the same time not cause damage to the water pipe, so that the water pipe can be used normally.

Precautions

In the antifreeze treatment of the tap water pipe, it is often the case that the tap water pipe has been frozen. If warm water is used when the tap water pipe is thawed, if there is still no water flowing out of the water meter, it means that the inside of the water meter is also frozen. You can wrap a hot towel on the water meter, and then sprinkle it with warm water. The temperature of the water should not exceed 30 degrees Celsius. Do not use fire to directly bake the water pipe. The most important point is to control the temperature of the pouring water. The above is the specific introduction of the editor on the anti-freezing techniques of water pipes. I hope everyone can learn from the anti-freezing technology of water pipes.
