Living and fire fighting shared pipe network pressure-superposed water supply system

Abstract

The invention discloses a living and fire fighting shared pipe network pressure-superposed water supply system. The living and fire fighting shared pipe network pressure-superposed water supply system is mainly composed of a non-negative-pressure controller, a flow stabilization regulation tank, a water pump, a safety valve, an air pressure water tank, a solenoid valve, a control cabinet, a domestic water point and a fire hydrant; in a normal situation, the water pump conducts non-negative-pressure frequency conversion and constant pressure water supply according to the pressure requirement of the domestic water point; and meanwhile, voltage stabilization for a looped network with the fire hydrant is carried out, when a fire fighting linkage signal is received, a fire fighting state is automatically switched to meet the pressure requirement of the fire hydrant for water supply, the solenoid valve is closed, and power frequency starting and power frequency running of the water pump are achieved. The living and fire fighting shared pipe network pressure-superposed water supply system has the beneficial effects that the functions of living non-negative-pressure frequency conversion and constant pressure water supply and fire fighting pressure water supply are achieved; in addition, the investment and the occupied land are saved, installation and maintenance are quite convenient and simple, the water supply pressure of the system is stable, and the protection function is complete; and when being used in occasions with the requirements for the living and fire fighting water supply, the system has the better practical value and the better prospect.

Description

technical field [0001] The invention relates to the technical field of secondary water supply, in particular to a superimposed water supply system of pipe network for domestic fire protection. Background technique [0002] In the secondary water supply of high-rise buildings with tap water as the water source, it is often necessary to set up pressurized equipment for the domestic water supply system and the fire-fighting water supply system at the same time. The fire-fighting pressurized water supply equipment is equipped with a fire-fighting pool and a special fire-fighting stabilized pump device, which not only takes up a lot of installation space, but also has high investment costs and troublesome installation, management and maintenance. Contents of the invention [0003] The purpose of the present invention is to provide a water supply system with a simple structure, less land occupation, and low investment, which is a pipe network superimposed for domestic fire prote...
