Totally closed negative-pressure-free additive pressure water supply device

Abstract

The invention relates to a water supply device, in particular to a totally closed negative-pressure-free additive pressure water supply device. The totally closed negative-pressure-free additive pressure water supply device comprises a water storage tank, an energy storage flow stabilizing tank, an air supplementing device, a stabilizing tank, a suction-type stabilizing pump, a pressure sensing element, a liquid level sensing element, an electric control cabinet, an antifouling breaker, valves, connecting pipes and the like. The totally closed negative-pressure-free additive pressure water supply device is characterized in that a water storage unit is composed of the water storage tank and the energy storage flow stabilizing tank which are three-dimensionally disposed with an upper layer and a lower layer and in a totally closed structure; a pressure compensating unit is composed of the energy storage flow stabilizing tank, the air supplementing device, an electric-air valve and connecting elements; the suction-type stabilizing pump which is mounted on the upper layer of the water storage tank serves as a stabilizing pump of a variable frequency compressing unit. The totally closed negative-pressure-free additive pressure water supply device is disposed in a three-dimensional layered manner, large in water storage amount, low in floor space and pollution-free, and gets water directly from municipal water supply network to pressurize, and can supply water continuously to the water supply network during busy hours of water use.

Description

technical field [0001] The invention relates to a water supply device, in particular to a fully enclosed non-negative pressure laminated water supply device. Background technique [0002] The traditional secondary water supply method is inseparable from the reservoir. The water in the reservoir is generally supplied by the tap water pipe network. In this way, the pressure of the originally pressurized water enters the reservoir and becomes zero, and then pressurizes from zero. Cause a lot of waste of electricity and energy; In addition, there are secondary pollution, running, leaking, dripping and other series of problems in the open storage tank, and the storage tank needs to be cleaned regularly every year, not only the quality of water supply is poor, but also the cost of water supply is high . [0003] Ordinary superimposed water supply devices use water pumps directly connected to the water pipe network, use pressure regulating tanks as water pump water storage devices...
