Secondary water supply system for high-rise water supply

Abstract

The invention discloses a secondary water supply system for high-rise water supply. The secondary water supply system comprises a water storage tank, a pressure stabilizing tank and a main water supply pipe, wherein a pressure control float valve structure is arranged in the water storage tank; a gas retaining float valve structure is arranged in the pressure stabilizing tank; the pressure controlfloat valve structure comprises a pressure control floating body, a pressure control connecting rod, a pressure control gas hole and a pressure control valve ball; the gas retaining float valve structure comprises a gas retaining floating body, a gas retaining baffle, a gas retaining gas hole and a gas retaining valve plate; a pressure stabilizing connecting pipe is arranged below the pressure stabilizing tank; a pipe pressure stabilizing hole is formed in the side wall of the main water supply pipe; a tank pressure stabilizing hole is formed in the bottom of the pressure stabilizing pipe; the upper end of the pressure stabilizing connecting pipe communicates with the tank pressure stabilizing hole; and the lower end of the pressure stabilizing connecting pipe communicates with the pipe pressure stabilizing hole. The secondary water supply system has the beneficial effects that the secondary water supply system has certain flow adaptive adjustment capability, can guarantee the relative stability of flow in the water use peak period, also has certain automatic buffer capability, can effectively cope with the water hammer phenomenon, can protect main pipelines and can also guaranteethe relative stability of water pressure when users use water.

Description

technical field [0001] The invention belongs to the technical field of secondary water supply and high-rise water supply, and in particular relates to a secondary water supply system for high-rise water supply. Background technique [0002] The secondary water supply device (or system) is a commonly used high-rise water supply device. It pressurizes the water in the municipal water supply network through pressurization equipment such as a booster pump and then enters the water storage structure (or transfer structure) at a high place. Then it is output to each user pipe through the main water supply pipe, so as to give each high-level user who needs water. The municipal water supply network itself has a certain water supply pressure. For low-level users, the water supply pressure of the municipal water supply network can directly supply water to the households. However, for high-level users, the water supply pressure of the municipal water supply network is insufficient. In...

AI Technical Summary

Problems solved by technology

When the pressurization equipment such as the pressurization pump assists in water supply, and when the user is using water, the water pressure in the pipeline may suddenly change greatly, which will easily lead to the "water hammer phenomenon", so that the pipeline, especially the main Damaged pipes (the main pipe here is mainly the main water supply pipe mentioned above)
