1. Under what circumstances do you need to vent the radiator
1. The radiator is not hot as a whole, which may be due to the fact that the outdoor water inlet and the return water valve are not open.
2. The local part of the single household is not hot, which may be caused by the fact that the top floor is not vented.
3. The radiator is half hot and half cool, which is caused by the accumulation of gas at the tail.
In short, under the condition of ensuring the circulating pressure and temperature, the main reason for not heating is air blockage, which can be solved by proper air release.
Second, why should the radiator deflate
During the operation of the radiator system , there will be gas constantly generated inside the pipeline, and these gases are stored at the highest point of the system. When these gases accumulate to a certain level, the phenomenon of “air blockage” will occur, hindering the movement of water in the system pipeline, and the heat conduction radiator will appear. The appearance of no heat or uneven heat, so it needs to be deflated.
Three, five steps of radiator deflation
1. What is the radiator exhaust valve?
The radiator exhaust valve, also known as the radiator run off. The exhaust valve is an inconspicuous but vital device in the entire radiator system. The exhaust valve is generally installed at the top of the radiator and looks like a small screw.
During the operation of the entire radiator system, gas will be continuously generated inside the pipeline, and these gases will be stored at the highest point of the system. ” phenomenon, which hinders the flow of water in the system pipeline, and the heat conduction radiator is not hot or unevenly heated. Therefore, the air release valve is an indispensable part of the radiator heating system.
2. After knowing the vent valve on the radiator, we can teach you how to get the radiator to deflate.
⑴Users should first check whether the inlet valve of the pipeline is open.
⑵Close the inlet and outlet valves of the radiator at home.
⑶ When the upper and lower valves are closed, the user gently loosens the air release valve, and immediately stops twisting the air release valve after hearing the sound of gas being discharged, so that the gas can be exhausted by itself. Since the gas in the radiator is accumulated on the top of the radiator, it is easy to release the gas under the action of atmospheric pressure.
⑷ Gently loosen the water inlet valve until there is a steady flow of water, and then close the air release valve. You must be patient in this step, just unscrew it a little and hear the sound of water, otherwise the gas will not be easily discharged.
⑸ Repeat the action in step 4 several times until all the gas is exhausted. Some users have a lot of gas in the radiator system pipes in their homes, which requires repeated exhaust to ensure the stability of heating.
Fourth, what are the precautions for radiator deflation?
The main problem with poor heating is the accumulation of air in the pipes, which can lead to poor water circulation. When residents put water on the radiator, what is actually released from the radiator is gas, but the amount of water released is very small. Some residents do not understand. Insufficient storage, resulting in the heating not reaching the temperature it should be.
In the process of deflating the radiator, many residents accidentally unscrewed the exhaust valve, and the water in the pipe spurted out, and the floor and furniture of the house were flooded. IKEA’s well-known brand radiator HVAC experts offer advice. If the user accidentally twists the exhaust valve, they can immediately find a wooden chopstick, sharpen one end, and insert it into the exhaust hole to avoid a lot of water leakage. Then, find a professional for repairs.
In addition, users should pay special attention to the fact that “venting” is not the same as “releasing water”. “Watering” is actually a misunderstanding, which is not only ineffective, but also gets colder and colder, and even affects the entire building. Because the pressure of the heating is constant, if the user puts water in the house, it will cause the heating station to continuously add “cold water” to fill, and as a result, the pipe becomes cooler and cooler. If there is too much water in a building, the whole building will freeze, and there is no scientific reason for “watering”.
There are many reasons why the radiator is not hot, and venting the radiator is one of the common ways to solve the problem of the radiator not being hot. The use effect of the radiator is related to the three parts of design, installation and after-sales. Therefore, a professional and guaranteed HVAC company is required for installation and debugging to avoid various problems during use, and to enjoy professional service after failure. After-sales service.
