The installation of floor heating is convenient for the elderly and children. However, if things are used for a long time, it will inevitably lead to problems, such as the leakage of water to the floor . If we encounter such a problem, what should we do? Today, we come to a good understanding of how to do a warm leak ?
Floor heating leakage, processing steps 1, first consider the set, the water separator and the heating coil connection
It is a weak link, because the thermal expansion coefficient of plastic pipe and copper joint heating is different, plastic pipe and copper joint in the space heating system is easy to produce thermal expansion and contraction phenomenon, and this phenomenon is especially in the radiator and plastic pipe Water seepage often occurs in the connection.
Floor water leakage, process step 2, pressure test
The best way to detect whether there is water leakage by leaking water is to re-do a pressure test. When the floor is warm, a pressure test must be done: Turn off the floor heating valve, use a manual pressure machine to warm the floor, and wait for half an hour if the pressure is 8 to 10 kg. If the pressure can be maintained, the heating pipe will not leak. If it leaks, the water leak will be obvious and the pressure will be difficult to maintain for a long time.
Floor water leakage, processing step 3, observation of pressure gauge changes
Under normal circumstances, if it is determined that there is water leakage from floor heating, the pressure gauge will generally fall in a short period of time. When it is determined that it is a slow leak, first of all, let the pipeline stop running. After the warm surface is cooled down, pressurize it with hot water. Close all valves on the water separator and observe the pressure gauge to determine that the pressure gauge has not changed.
Floor water leakage, process step 4, determine the leakage circuit
Open the valves of each circuit separately, and observe which circuit has a pressure drop phenomenon. Generally, a circuit with obvious pressure drop is a leakage circuit. After confirming the leaking circuit, turn off all the loops without leakage, and then fill the pipeline with warm water to the ground to adjust the water temperature to the maximum temperature for warm water circulation. At this point, the pressure gauge will gradually decrease. When warming up, pay attention to maintaining the pressure value of the floor heating pipe. After the leakage floor heating circuit is started, use an infrared thermometer to measure the temperature of the ground surface.
During the initial measurement, it will be found that the surface will have a certain temperature difference. This temperature difference is generally linear, that is, the direction of the laying of warm pipes during installation. Do not close the valves on the water separator and observe the pressure gauge to make sure that the pressure gauge has not changed.
Warm water leakage, processing step 5, determine the leaking point
With the extension of time, the surface temperature gradually rises, and the determined leaky pipe temperature will rise very high. A peak will be formed at the leak point where the temperature of the leak point will be much higher than the temperature of other parts of the pipe. When the leakage point area is determined, the determination of the center point is performed. Generally, the center of the leakage point is usually the place with the highest temperature. According to this, the user can roughly determine the center position of the leakage, and then a small area of ​​ground can be drilled. Floor heating pipe for inspection and maintenance.
The above is the related content of warm water leakage , I hope to help you, more decoration information, all in this site, so stay tuned.
