Mounting method of individually-charged heating pipelines

Abstract

The invention discloses a mounting method of individually-charged heating pipelines. A double-pipe circular reversed return system is adopted, and the heating pipelines comprise a fixed heating pipeline and a spare heating pipeline. A vertical branch pipe of radiators is externally mounted while a main vertical drain pipe is mounted in a pipe well; drain valves are respectively mounted on main feeding and backwater pipes of all household embedded pipes, and two drain valves are communicated by a tee joint and is communicated with the main vertical drain pipe in the pipe well. The mounting method reduces the crossed times and the time for mounting and the civil engineering of the heating pipelines, improves the working efficiency and the quality of the mounting and the civil engineering of the heating pipelines, reduces on-site melting joints, facilitates the cleaning and the draining of the heating pipelines individually measured, ensures the cleanness of the heating pipelines individually measured and improves the working conditions of heat meters individually measured, thereby prolonging the service life of the heat meters.

Description

[0001] This patent application is a divisional application, and the application number of the original application is 200810050084.4. technical field [0002] The invention relates to an installation method of household metering heating pipelines. Background technique [0003] In order to save energy, household metering should be adopted in the central heating design of commercial buildings. But in fact, household metering is difficult to promote. An important technical reason why household metering is difficult to promote is that the service life of heat meters is short, and the cleanliness of water in the heating system is difficult to guarantee. The existing household metering heating pipelines are all welded together. Except for the detachable radiator, other pipelines cannot be disassembled and cleaned. However, it is difficult to ensure the cleanliness of the pipelines by flushing the entire system, resulting in Granular dirt is not easy to discharge. After being heat...

Problems solved by technology

[0005] The water intake of the last group of radiators in the single-pipe series indoor system comes from the return water of the previous group of radiators, which will cause the following problems: except for the water in the last group of radiators that can be drained, the other radiators The water stored in the radiator cannot be completely drained. If the pressure is tested in winter and the antifreeze is not done well, except for the last group of radiators, other radiators will be damaged by freezing, and the dirt with a high density in the buried pipe cannot be discharged, that is, sand Dirt such as particles and metal welding slag cannot be discharged

The disadvantage of this system is that it uses less than twice as many buried pipes as the single-pipe series system, and the cost is slightly higher than that of the single-pipe series system. However, this system solves the problems in the first two systems and is suitable for The system form of buried pipe heating

Since the installation of the heating pipeline and the construction of the civil engineering are carried out repeatedly, not only the progress of the project is affected by each other, but also the quality of the installation of the heating pipeline and the construction of the civil engineering are affected. As a result, the radiator is repeatedly polluted by cement mortar and paint, and the installation of window frames and glass Often there is a phenomenon of stepping on the radiator, causing the fixed radiator to loosen, and the heating pipeline that has been tested and pressure leaks again. Need to repaint and repair the pipeline

[0010] After the existing commercial housing is handed over, many owners want to remove the exposed heating pipes and radiators, reinstall the hidden pipes, and choose high-end radiators with beautiful appearance. Many owners also want to change the position of the radiators. This shows that the existing The design and installation method of the heating pipeline is no longer suitable for the pursuit of individualized requirements of the fast-growing Chinese people, resulting in a waste of limited resources and labor
