The disadvantage is that when the residents on the upper or lower consecutive floors (or more floors) stop heating because they have not paid the heating fee, the water accumulated at the upper end of the water supply riser or the lower end of the return riser of the indoor system may become Stagnant water that does not flow, this section of the pipeline is easy to freeze and damage in cold weather

Embodiment Construction
[0010] See figure 1 , the antifreeze method in the household heating renovation design. This method adopts antifreeze connecting pipes at the top and bottom of the water supply riser and return water riser of the indoor system, so that the water supply riser and the water supply riser at the top and bottom of the indoor system and The backwater standpipe is connected to maintain hot water circulation, and a locking regulating valve is set on the antifreeze connecting pipe.
[0011] The antifreeze system is composed of water supply standpipe 1, water supply indoor branch pipe 2, return water indoor branch pipe 3, return water standpipe 4, antifreeze connecting pipe 5, and lock regulating valve 6. The circulating water of the civil heating system is composed of water supply standpipe 1 First enter the households on the first floor (or the top floor households), and then go up (or down) into the households on other floors in turn until the top floor (or bottom floor). One side of...

The invention relates to an antifreezing method in the design of civil heating household reconstruction, which comprises the following steps: mounting antifreezing communicating pipes on the top and the bottom of a water supply standpipe and a back water standpipe of an indoor system respectively; communicating the water supply standpipe and the back water standpipe on the top and the bottom of the indoor system to keep the hot water circulation; and mounting locking and adjusting valves on the antifreezing communicating pipes. The method has the following advantages: uniquely designing the antifreezing communicating pipes on the prior heating system, skillfully mounting the locking and adjusting valves on the antifreezing communicating pipes, and with the combination, reducing the probability of frost damages to the pipelines in corridors, reducing the loss of heating units, and greatly ensuring the heating effect of heating devices.
Description
technical field [0001] The invention relates to an antifreeze method in household heating renovation design. Background technique [0002] The water supply standpipe of the existing civil heating system first enters the households on the first floor or the households on the top floor, and then enters the households on other floors sequentially up or down until the top floor or the bottom floor. The water supply vertical pipe has a water supply indoor branch pipe connected to the radiator in each household, and the last group of radiators is connected to the return water vertical pipe through the water return indoor branch pipe. The disadvantage is that when the residents on the upper or lower consecutive floors (or more floors) stop heating because they have not paid the heating fee, the water accumulated at the upper end of the water supply riser or the lower end of the return riser of the indoor system may become Stagnant water, this section of pipeline is easy to freeze ...
