A new type of non-negative pressure water supply equipment relates to water supply equipment for high-rise buildings. The tap water pipe is connected to the steady flow regulating tank, and the water outlet pipe at the bottom of the steady flow regulating tank is connected to the water supply pipe through a butterfly valve connected in series with a check valve. The two ends of the tap water straight-through pipeline are connected in parallel with the pressurized pipeline, including a first butterfly valve, a booster water pump, a check valve and a second butterfly valve connected in sequence. The steady flow regulating tank is equipped with a negative pressure suppressor and a liquid level detection device. The two ends of the straight-through pipeline for tap water are also connected in parallel with a pressure-increasing pipeline. The water supply pipe is also connected with the pressure compensation tank. The utility model has the advantages that a pressure compensation tank is provided, and when the water supply pressure remains, the capsules in the pressure compensation tank are filled with water for pressure pre-storage, and when the pressure of the pipe network fluctuates slightly, the pressure compensation tank first performs pressure compensation adjustment. When there is a small fluctuation in the water supply network and further loss of pressure, a small flow boost pump is started to supplement the pressure. When the pipeline network further loses pressure, the large-flow booster pump in the booster pipeline is started to boost the pressure, and the pressure supplement and boost are started step by step. The equipment saves energy, reduces consumption, reduces dryness, and operates economically.
Description
Technical field:
The utility model relates to supply equipment, the non-negative pressure water-supply installation that particularly utilizes the tap water pipe network to supply water for high-rise building.
Background technology:
At present, the tap water pipe network generally can only guarantee the pressure of supply water of certain altitude, and it is very low to be in terminal ductwork pressure, and high-rise building just runs out of water, and the building of lid is more and more higher now, and building water supply has become problem.Be high-floor feedwater if adopting directly draws water from the tap water pipe network, then will cause to occur negative pressure in the pipe network, influence other user's water.If take to build the pond and add the way that booster water pump supplies water, the pond is uncovered easily contaminated again, and builds the pond investment greatly.Now, develop various non-negative pressure water-supply installations gradually, need not build the pond make-up water pump and supply water, non-negative pressure water-supply installation mainly is made of current stabilization regulating tank, booster pump unit, controller, the current stabilization regulating tank is provided with negative pressure inhibition device, can prevent during water supply that the pipe network negative pressure from producing, and guarantees non-negative pressure method of water supply.The weak point that existing non-negative pressure water-supply installation exists is, the end pressure of supply water fuctuation within a narrow range that supplies water is fallen when pressing, and also need start booster water pump, and starting mode of pump is frequent, and power consumption mechanical wear is big.It fails to be fully utilized when the surplus pressure of pressure of supply water during greater than user's request again, does not reach economical operation.
Summary of the invention:
Goal of the invention of the present utility model, provide a kind of novel non-negative pressure water supply equipment, have tap water straight-through pipeline, pressure piping, ftercompction pipeline three pipelines and connect characteristics, terminal feed pipe also and connect the pressure compensation jar gives Compensation Regulation by the pressure compensation jar earlier when water supply network minor swing decompression, further decompression starts the ftercompction pump ftercompction of low discharge, further decompression starts the supercharging of big flow booster pump again, energy-conservation, noise reduction, reduced investment, economical operation.
Can take following technical scheme for reaching the foregoing invention purpose, novel non-negative pressure water supply equipment comprises current stabilization regulating tank, booster pump unit, pipeline and switch board.Running water pipe 1 connects current stabilization regulating tank 4 water inlets, and current stabilization regulating tank bottom outlet pipe 10 connects feed pipe 11 through the straight-through pipeline of tap water of butterfly valve 8 serial connection flap valve 9.Straight-through pipeline two ends of tap water of butterfly valve 8 serial connection flap valve 9 also connect pressure piping, and pressure piping comprises first butterfly valve 13, booster water pump 14, first flap valve 15 and second butterfly valve 16 that connects successively.Negative pressure inhibition device 5 and liquid level detection device 6 are equipped with in described current stabilization regulating tank 4 its tops.The tap water of described butterfly valve 8 serial connection flap valve 9 leads directly to pipeline two ends also and is connected to the ftercompction pipeline, and the ftercompction pipeline comprises ftercompction water pump 20 and control valve.
A pressure compensation jar 21 is gone back and connect to described feed pipe 11, is filled with helium in jar, but also is provided with water-filled capsule 22.
The utility model has the advantages that:
Straight-through pipeline two ends of tap water also are connected to the ftercompction pipeline.Feed pipe also and connect the pressure compensation jar.Capsule is given pressure by water-filling and prestores in the pressure compensation jar when pressure of supply water remains, and when the ductwork pressure minor fluctuations, gives pressure compensation by the pressure compensation jar earlier and regulates.When the further decompression of water supply network minor swing, start the ftercompction pump ftercompction of low discharge.When pipe network more further during decompression, start the big flow booster pump supercharging of pressure piping, start ftercompction, supercharging step by step, this device energy conservation, lower consumption, fall dry, reach economical operation.
