Heating has almost all households in the north, and now people have high requirements for quality of life. Heating in the winter can bring us a very comfortable living environment. Today Xiao Bian wants to speak with everyone about the heating pipe installation method and related knowledge. We can all come together to understand together!
Heating pipe installation method
Single tube series
Single-tube series installation, the amount of material is relatively low, the transformation time is very short. Labor intensity is relatively weak. In the heating pipeline arrangement, the single-tube series is a common one. The water in the entire system is first passed through the system's first group of radiators, followed by the second group, the third group..... for this water temperature. It is gradually reduced in the order of the series.
Double pipe parallel decoupling
The parallel installation of the two pipes is parallel and the pipeline travel is short. Each radiator can be controlled independently. The flow balance of the system will be greatly improved compared to the single pipe series, and the temperature after use is more uniform. This type of heating pipe installation currently has certain limitations. Because the water flow rate of each set of radiators is different, the front-end backwater is closer to the main pipe, so the return is faster and the back-end water return is slower. This may cause the end of the heating not to be hot or hot.
Double-pipe parallel connection
The parallel operation of the two pipes is also referred to as double pipe synchronization. Its characteristics are basically the same as that of the double pipes. However, the two heating pipe installation methods have different operating principles. The parallel connection of the two pipes is the first connection for the first time. In simple terms, the first set of radiator system in the front end continues to go down and does not temporarily circulate to the main pipe, and is connected to the return pipe of the next set of radiators. Analogy .... When it reaches the end of the radiator, it will return a return pipe and return to the return pipe of the main pipe.
Heating pipe installation precautions
Pipe slope requirements
The installation of pipelines should have a slope. If there is no requirement for design, the slope should meet the following requirements: 1. Steam and condensate pipelines with hot water heating and hot water supply pipes and soda flowing in the same direction. In this case, the slope of the pipeline is general. For 0.003, note that it must not be less than 0.002; 2. Steam and condensate pipes with reverse flow of soda water generally have a slope of less than 0.005.
Pay attention to installing exhaust and drain devices
During the installation of indoor heating pipes, the pipes pass through doors and windows or from other openings, beams, columns, corners, etc. If the corners of the pipes go above or below the horizontal direction of the pipes, they should be at their highest or lowest point respectively. Install the exhaust and drain fittings so that the main function of the installation is to remove the air in the pipes and the dirt at the lowest point.
Set metal or reinforced casing
When the pipeline passes through the floor and the walls, it should be provided with a metal sheath or a steel casing. In this process, the bushing must meet the following two conditions: 1. The bushing installed in the wall should have both ends parallel to the wall finish so as to ensure that the pipe is not affected by the expansion and contraction. influences. At the same time, if there is water accumulation on the ground, it will not flow to the lower layer; 2. The casing installed in the floor should be parallel to the bottom of the floor, and the top should be 15-20 cm higher than the ground.
The above is the heating pipe installation method and installation precautions that Xiaobian brings to everyone. After reading the above introduction, we hope that we can help you. If you want to learn more about other related information, please continue to pay attention to this site. More exciting please. look forward to!
