Description
Technical field
The present invention relates to a kind of automatic water supply device, particularly a kind of non negative pressure steady flow automatic water supply equipment.
Background technology
At present general supply equipment can produce negative interaction after directly inserting the tap water pipe network, because the flow of water pump is usually greater than the running water pipe flow of inlet water, thereby causes ductwork pressure to descend, and influences peripheral user's water.In order to solve the irrationality of this water supply scheme, so traditional way of supplying water need be built 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 are pollution problem in water pump water source water tank and attic tank, because all there is overfall in the design in pond, the water tank of life usefulness also must regularly clean for avoiding water quality to degenerate, thereby has caused the waste of drinking water.The second, the building cost of attic tank is higher, and along with the development in city, attic tank also is difficult to see.The 3rd, the tap water in the city planting ductwork will be put into the water source water tank earlier 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, constitute by water tank, non retern valve, vacuum tank, pressure sensor, frequency conversion tank, feed pump, control valve, liquid level sensor, though this supply equipment has been cancelled attic tank, but it does not thoroughly solve the problem of traditional water supply scheme, though cancelled attic tank, because the existence of water pump water source water tank, pollute still not thoroughly solution, water supply and energy saving problem and low discharge problem all are not solved in addition.
Summary of the invention
The objective of the invention is to solve traditional water supply and the existing problem of constant pressure water supply device in the prior art, provide a kind of and can thoroughly solve the water pollution issue that the traditional water supply scheme causes because of secondary water-supply equipment and the non negative pressure steady flow automatic water supply equipment of energy dissipation, improve the reliability and the automaticity of original water supply scheme simultaneously.The present invention designs non negative pressure steady flow automatic water supply equipment, comprise into water non retern valve, vacuum tank, pressure sensor, frequency conversion tank, control valve, feed pump, liquid level sensor, it is characterized in that: a current stabilization jar that is connected with the tap water water inlet pipe is arranged, on the current stabilization jar, be connected to vacuum breaker, the outlet of current stabilization jar also is connected to few two water pumps and control valve, one outlet is arranged and connect three non retern valves, non retern valve connects exit of pump and control valve outlet respectively, be connected to vacuum tank and pressure sensor on outlet pipe, liquid level sensor, pressure sensor, feed pump connect frequency conversion tank.Advantage of the present invention is to prevent the water pollution that causes because of secondary water-supply equipment, will reduce waste of electric energy simultaneously.
Description of drawings
Below in conjunction with embodiment the present invention is elaborated,
The specific embodiment
Comprise into water non retern valve 1 among the figure, vacuum tank 2, pressure sensor 3, frequency conversion tank 4, control valve 5, feed pump 6, liquid level sensor 7, it is characterized in that: a current stabilization jar 9 that is connected with tap water water inlet pipe 8 is arranged, on current stabilization jar 9, be connected to vacuum breaker 10, the outlet of current stabilization jar 9 also connects two feed pumps 6 and control valve 5, one outlet 11 is arranged and connect three non retern valves 12, non retern valve 12 connects feed pump 6 outlets and control valve 5 outlets respectively, on outlet 11, be connected to vacuum tank 2 and pressure sensor 3, liquid level sensor 7, pressure sensor 3, feed pump 6 connects frequency conversion tank 4.The water of tap water pipe network enters current stabilization jar 9 by tap water water inlet pipe 8 during use, and jar 9 interior air are discharged from vacuum breaker 10, treat that water is full of current stabilization jar 9 final vacuum arresters 10 and closes automatically.When tap water pipe network pressure can satisfy the water requirement, system was directly supplied water to the water pipe network by bypass control valve 5, non retern valve 12; When tap water pipe network pressure can not satisfy the water requirement, the system pressure signal fed back to frequency conversion tank 4 by pressure sensor 3, and feed pump 6 operations are regulated rotating speed automatically according to the size of water supply volume and reached constant pressure water supply; When if running feed pump 6 reaches the power frequency rotating speed, then start another feed pump 6 frequency conversions running.When feed pump 6 supplied water, greater than pump capacity, system kept normal water supply as if tap water pipe network output; During water use peak, when tap water pipe network output during less than pump capacity, the water in the current stabilization jar 9 water source as a supplement still can normal water supply, at this moment, air enters current stabilization jar 9 by vacuum breaker 10, and jar 9 interior vacuum are destroyed, and have guaranteed that the tap water pipe network does not produce negative pressure; After the water use peak, system returns to the normal water supply state again.Cut off the water when the tap water pipe network, cause current stabilization jar 9 interior liquid levels constantly to descend, liquid level sensor 7 is given frequency conversion tank 4 with signal feedback, and system's autostop is also reported to the police, with the protection water pump assembly.When night, low discharge water supply and tap water pipe network pressure can not meet the demands, vacuum tank 2 can be stored and release energy, and has avoided the frequent starting of feed pump 6.System efficiently solves that secondary water-supply equipment directly inserts the tap water pipe network and the negative pressure problem that causes, thereby makes second pressure water supply equipment save the pond and directly insert the tap water pipe network; Effectively utilized simultaneously the pressure of tap water pipe network, select for use the lift of water pump to reduce, thereby the power of motor of coupling is little, the cost and the operating cost of complete equipment have all reduced, in addition, when tap water supply pressure can be met consumers' demand, system can not open feed pump 6 and flow directly into user's pipe network by bypass control valve 5, had so just saved the energy widely; Because this secondary water-supply scheme has been saved the pond fully, simultaneously, the water that water pump and pipeline are all selected for use stainless steel product to eliminate fully and caused because of second pressure water supply equipment pollutes; This water supply scheme has also been considered the public safety problem, when dropping into hazardous substances because of artificial destruction in the secondary water-supply pipeline, the water inlet that flows into current stabilization jar 9 is provided with into water non retern valve 1, prevents the anti-city planting ductwork that flows into of water in the secondary pressurized equipment, thereby enhances public security.
