Abstract

The invention relates to the technical field of high-rise domestic hot water pipelines, in particular to a high-rise domestic hot water centralized decompression circulating pipeline system which comprises an outer tube and an inner tube, wherein the inner tube penetrates through the outer tube and is located on the center line of the outer tube, the two ends of the outer tube are in sealed connection with the inner tube, the inner tube directly communicates with a hot water source, and the outer tube communicates with the hot water source through a decompression valve; and a plurality of user water outlets are formed in the outer tube. Hot water from the upper pipeline enters the decompression valve and the inner tube, the hot water from the decompression valve flows in a cavity formed by the inner tube and the outer tube, the hot water flowing in the inner tube supplements heat lost by the outer tube, so that the water temperature of a water using point meets the requirements; hot water in the inner tube does not pass through the decompression valve, thus not affecting the circulation of the system, and meanwhile, the water temperature requirements of a user are met. In addition, only a large decompression valve is arranged at a header tube of a low-area system, so that the pressure of the whole subarea meets the requirements, and meanwhile, the whole water supply system is ensured not to be overpressure in operation.

Description

technical field [0001] The invention relates to the technical field of high-rise domestic hot water pipelines, in particular to a high-rise domestic hot water centralized decompression circulation pipeline system. Background technique [0002] The existing centralized high-rise domestic hot water belt circulation system requires a pressure reducing valve on each floor. If there are many water points on the entire flat floor, many pressure reducing valves need to be installed on each floor, resulting in project investment and Difficulty in debugging increases and there is no possibility of back-up for the pressure reducing valve, resulting in insufficient reliability of water supply. This kind of system does not increase the cost, and at the same time reduces the applicable amount of the pressure reducing valve, and reduces the cost of commissioning and operation and maintenance. Contents of the invention [0003] The invention provides a high-rise domestic hot water centr...
