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