Embodiment Construction
[0020] Such as figure 1 , figure 2 As shown, a multi-water source multi-directional non-negative pressure water supply method, the most unfavorable point of water use in the water pipe network, preferably located at a high place, is provided with a non-negative pressure secondary water supply high-pressure water storage tank, and a filling tank is set in the tank. There is a diaphragm air bag with compressed air, so as to realize the non-negative pressure water supply of multiple water sources and multiple directions.
[0021] The most unfavorable point for water use refers to the point in the water pipe network that is far away from the water supply equipment, and the preferred solution is the high point of this point.
[0022] A non-negative pressure secondary water supply high-level pressure water storage tank, the pressure tank 3 is provided with a diaphragm air bag 2, the diaphragm air bag 2 is connected to the air inlet 4, and a vent valve 7 and a water supply valve 8 ...

The invention provides a multi-water-source multi-way non-negative-pressure water supplying method and device, relating to a water supplying method; in the multi-water-source multi-way non-negative-pressure water supplying method, the most disadvantageous point of the water tube net is that a non-negative-pressure secondary water supplying high-position pressure type water storage tank is arranged preferably at a high point; and a membrane air bag filled with compressed air is arranged inside the water storage tank so that the multi-water-resource multi-way non-negative-pressure water supplying is realized. In the invention, the water can be injected while the pump operates; when the pump is dormant, the multi-water-source water supplying system for a water pipe net is formed, can carry out the replenishment of water quantity in a short time, and has the effects of stabilizing pressure and flow; the powerless pressure-maintaining operation with small or zero flow quantity can be reached; and the method and the device ensure that the energy is saved, the operation cost lowered, and the device abrasion is reduced.
Description
technical field [0001] The invention relates to a water supply method, in particular to a method and equipment for non-negative pressure frequency conversion water supply and secondary water supply. Background technique [0002] Non-negative pressure secondary water supply equipment, including non-negative pressure superimposed water supply equipment, intelligent non-negative pressure pressurized water tank, non-negative pressure pipeline pressurized water supply equipment, non-negative pressure non-suction pipe network pressurized steady-flow water supply equipment, etc. , is a new type of water supply equipment after water tank (water tower) water supply, air pressure water supply, frequency conversion speed regulation water supply, has the advantages of fully enclosed, pollution-free, energy-saving, less land occupation, quick installation, reliable operation, and convenient maintenance. However, it fails to solve the three problems of water pumps, including the direct wa...
