Secondary constant-pressure water supply system of high-rise building

Abstract

The invention relates to a secondary constant-pressure water supply system of a high-rise building, which comprises a variable-frequency speed-regulating primary constant-pressure water supply device, a main pipe, constant-pressure water flow servo valves of a secondary constant-pressure water supply device and floor water branches. The variable-frequency speed-regulating primary constant-pressure water supply device is placed in a sectional manner according to the height the high-rise building, sections of the variable-frequency speed-regulating primary constant-pressure water supply device are serially connected via the main pipe, the main pipe is located at the center of the building and is arranged perpendicularly, the floor water branches are horizontally arranged from the main pipe to two sides of the building, the constant-pressure water flow servo valves are mounted at inlets of the floor water branches, secondary constant pressure is realized by the constant-pressure water flow servo valves, the problem that water supply pressures of the various floor water branches are inconsistent due to height change when in primary constant-pressure water supply is resolved, and water supply quality is high. The secondary constant-pressure water supply system is simple in structure, does not increase control and management difficulty, is high in reliability and small in occupied space of the building, and does not increase running noise of equipment, and secondary pollution of running water is avoided.

Description

Technical field: [0001] The invention relates to the technical field of constant-pressure water supply, in particular to a secondary constant-pressure water supply system for high-rise buildings. Background technique: [0002] With the rapid development of economy and the continuous expansion of city scale, a large number of high-rise and super high-rise buildings have appeared. The water supply of high-rise buildings generally adopts the water supply method of secondary pressurization. At present, the most advanced method is to use a multi-stage relay constant pressure water supply system to realize the secondary pressurized water supply, which avoids the traditional method of using water tanks for secondary pressurization, which may cause Secondary pollution of tap water and occupation of building space by water tanks. [0003] The multi-stage relay constant pressure water supply system first divides the building into three areas: the low area (1-17 floors), the middle ar...

AI Technical Summary

Problems solved by technology

[0004] The multi-level relay constant pressure water supply system still has the defect that the water pressure difference between the bottom and high-rise users in the same area is too large, and the method of further reducing the number of partition layers and increasing the number of relay stages to reduce this water pressure difference requires not only a large Increasing investment will make operation control more difficult and reduce reliability, and further increase the space occupied by constant pressure water supply equipment in buildings, and further increase the operating noise of constant pressure water supply equipment

Therefore, it is necessary to find another way to overcome the defect that the water pressure difference between users is too large
