Pressure-superposed water supply device

Abstract

The invention discloses a pressure-superposed water supply device and relates to a water supply device for a high-rise or small high-rise storied building. The pressure-superposed water supply device comprises a regulation tank, a pressure superposition device and a control cabinet, as well as an ultraviolet water purifier, a pressure-stabilizing and energy-storing tank and a nitrogen bottle, wherein the water outlet of the regulation tank is connected with the water inlet of the ultraviolet water purifier, the water outlet of the ultraviolet water purifier is connected with the water inlet of the pressure superposition device, the water outlet of the pressure superposition device is connected with the pressure-stabilizing and energy-storing tank, a water supply interface is arranged on apipeline used for connecting the water outlet of the pressure superposition device with the pressure-stabilizing and energy-storing tank, the nitrogen bottle is respectively communicated with the upper part of the cavity of the regulation tank and the upper part of the cavity of the pressure-stabilizing and energy-storing tank via a pressure reduction valve, liquid level meters are respectively arranged on the regulation tank and the pressure-stabilizing and energy-storing tank, and a pressure gauge is arranged on the pressure-stabilizing and energy-storing tank. The pressure-superposed watersupply device can sterilize and disinfect tap water and further provide the tap water for a user, even a tap water pipeline is polluted, the user can safely and securely use the tap water; when the user uses a small amount of the water, the pressure in the water supply pipeline drops slowly, and the pressure-superposed water supply device is small in number of starts of a pressurization pump and low in energy consumption.

Description

technical field [0001] The invention relates to water supply equipment for high-rise or small high-rise buildings, in detail it is a laminated water supply equipment. Background technique [0002] We know that the existing stacked water supply equipment for high-rise or small high-rise building water supply includes a regulating tank, a stacking device and a control cabinet, the water outlet of the regulating tank is connected with the water inlet of the stacking device, the sensor in the control cabinet and the equipment, the stacking pressure device etc. When in use, the water inlet of the regulating tank is connected to the tap water pipe, and the water outlet of the stacking device is connected to the water supply pipeline. The stacking device will stack the tap water in the regulating tank and deliver it to the user through the water supply line. The device is functioning normally. This laminated water supply equipment has the following disadvantages: 1. There is no ...

AI Technical Summary

Problems solved by technology

This laminated water supply equipment has the following disadvantages: 1. There is no sterilization and disinfection function. When the tap water pipeline is polluted, the polluted tap water can only be provided to the user, and there is a safety hazard in the user's water; 2. When the user When a small amount of water is used, the pressure in the water supply pipeline will drop sharply, and the water supply pressure fluctuates greatly. The control cabinet immediately controls the operation of the lamination device to pressurize the water supply pipeline according to the signal from the sensor. The booster pump of the lamination device starts frequently and consumes energy. Big
