Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline direct drinking water systems, and in particular relates to a correction device for different-course pipe networks of pipeline direct drinking water systems. Background Art

[0002] According to the "Technical Specifications for Piped Drinking Water Systems in Buildings and Residential Areas" (CJJ / T110), the pipe network of the piped drinking water system should be laid out as a uniform circulation network, that is, the sum of the lengths of the supply and return pipes at each water distribution point (household pipe) in the piped drinking water network should be equal or approximately equal. The purpose of this layout is to keep the sum of the resistance losses of the supply and return pipes at each water distribution point (household pipe) roughly equivalent, achieving hydraulic balance and essentially preventing dead water or stagnant water. However, during actual construction, due to force majeure, it is impossible to lay the zoned pipe networks between the various zoned water supply systems in a uniform manner, resulting in unbalanced return water volumes. In some zoned water supply systems, the return water flow is very small or even non-existent (no circulation), resulting in dead water and stagnant water, and the water quality at the distribution points may deteriorate.

[0003] To this end, the utility model provides a correction device for different pipe networks of a pipeline direct drinking water system. Utility Model Content

[0004] The utility model is intended to provide a correction device for different-stage pipe networks of a pipe direct drinking water system, to correct the flow and pressure of different-stage partitioned pipe networks of the partitioned water supply system of the pipe direct drinking water system in the above-mentioned background technology, to reasonably allocate the partitioned water supply and return water flow in the partitioned water supply system, to achieve flow balance between the partitioned water supply systems, and to ensure the circulation effect of direct drinking water in the partitioned pipes of the pipe direct drinking water system.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0006] A correction device for different pipe networks of a piped drinking water system includes water transmission and distribution equipment, a water supply pipe, a return pipe, a zoned water supply system, and a correction device;

[0007] The water transmission and distribution equipment is designed and manufactured according to the direct drinking water network conditions, and the direct drinking water disinfection, water supply and circulation preservation devices are matched with the network;

[0008] The water supply pipeline is the main water supply pipe connecting the water transmission and distribution equipment with water supply branch pipe 1, water supply branch pipe 2, and water supply branch pipe 3;

[0009] The return pipe is the main return pipe connecting return branch pipe 1, return branch pipe 3, return branch pipe 3 and the water transmission and distribution equipment.

[0010] The sectional water supply system is a water supply system for different buildings, different water supply areas or different water-using devices in the direct drinking water pipeline system. The sectional water supply system includes sectional water supply system one, sectional water supply system two, and sectional water supply system three. The pipe network of the sectional water supply system consists of water supply branch pipe one, water supply branch pipe two, water supply branch pipe three, and return water branch pipe one, return water branch pipe two (32), and return water branch pipe three;

[0011] The correction device consists of multiple components, including correction device one, correction device two, and correction device three;

[0012] Correction device one includes water supply valve one, water supply flow regulating valve one, return water flow regulating valve one, return water valve one, and return water adjustable pressure reducing valve one.

[0013] The beneficial effects produced by this technical solution compared with the prior art:

[0014] The innovation of the present utility model lies in setting a correction device on the sectional water supply pipeline network of the direct drinking water pipeline system to correct the flow and pressure of different process pipe networks in each sectional water supply system, achieve the flow balance between each sectional water supply system, and achieve the same circulating water supply effect as the same-process pipe network.

[0019] In this embodiment, in the district water supply systems one (41), two (42), and three (43), the water supply branch pipes and return water branch pipes of each water distribution point within the same district water supply system are laid in the same path, while the water supply branch pipes and return water branch pipes of each water distribution point between different district water supply systems are laid in different paths.
