Description
Technical field
The utility model belongs to supply equipment technical field, is specifically related to a kind of box laminating water supply equipment.
Background technology
Can negative interaction be produced after general supply equipment directly accesses tap water pipe network at present, because the flow of water pump is usually greater than running water pipe flow of inlet water, thus cause ductwork pressure to decline, affect periphery user water.In order to solve the irrationality of this water supply scheme, so traditional way of supplying water needs to build water source water tank and attic tank in the import department of water pump, there are three problems in this traditional water supply scheme, first, all easily there is pollution problem in water pump water source water tank and attic tank, because the design in pond all exists overfall, the water tank of life also must periodic cleaning for avoiding water quality to degenerate, and thus causes the waste of drinking water.The second, the building cost of attic tank is higher, and along with the development in city, attic tank is also difficult to see.3rd, the tap water in city planting ductwork first will be put into water source water tank and then be extracted into attic tank with water pump, and like this, the pressure energy of tap water has just been wasted.
In order to overcome above-mentioned problem, existing a kind of constant pressure water supply equipment, be made up of water tank, non retern valve, vacuum tank, pressure sensor, frequency conversion tank, feed pump, control valve, liquid level sensor, though this supply equipment eliminates attic tank, but it does not thoroughly solve the problem of traditional water supply scheme, although eliminate attic tank, due to the existence of water pump water source water tank, pollute and still thoroughly do not solve; Water supply and energy saving problem and low discharge problem are not all solved in addition.
