Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the utility model further.
With reference to Fig. 1-2, this detailed description of the invention is by the following technical solutions: non-negative pressure water-supply installation, comprise Intelligent control cabinet 1, steady-flow tank tank body 2, all steel pump 3, Wafer Check Valves 4, wafer type butterfly valve 5, water inlet supervisor 6, draining valve 7, water outlet main pipe 8, bypass pipe and inlet pressure tank 9, steady-flow tank tank body 2 is connected with water inlet supervisor 6, water inlet supervisor 6 is by Wafer Check Valves 4, wafer type butterfly valve 5 is connected with all steel pump 3, all steel pump 3 is connected with water outlet main pipe 8, water outlet main pipe 8 is provided with draining valve 7, described water outlet main pipe 8 is also connected with multiple bypass pipe, inlet pressure tank 9 is connected with water inlet supervisor 6, Intelligent control cabinet 1 is connected with all steel pump 3 with inlet pressure tank 9.
It should be noted that described steady-flow tank tank body 2 is non-negative pressure stabilized tank.
It should be noted that described Intelligent control cabinet 1 is computer transduce switch board.
In addition, described Intelligent control cabinet 1 is also connected with pressure sensor, and pressure sensor is arranged in water outlet main pipe 8, for monitoring hydraulic pressure.
The operating principle of this detailed description of the invention: when equipment normally comes into operation, the water of city planting ductwork enters non-negative pressure stabilized tank, and the air in tank flows out in a large number from outlet valve, when air is drained, valve inner float ball is floated by water, and transmission chock plug is to fastening position, slowly close exhaust opening, stop exhaust, prevent water outlet, when current are normally carried in steady-flow tank, if any a small amount of air accumulation at Fa Nei road certain degree, water level decreasing in valve, ball float declines thereupon, and now air is then discharged by steam vent; Equipment normally runs in engineering, when city planting ductwork water-supply shortages, when municipal administration water inlet pipe in-pipe flow is empty, or when in steady-flow tank, hydraulic pressure is lower than atmospheric pressure, water level decreasing in steady-flow tank, ball float declines thereupon, drive chock plug is opened, suck air, make to keep atmospheric pressure in steady-flow tank, be unlikely to produce negative pressure to city planting ductwork.
When pressure in city planting ductwork is lower than setting pressure needed for user, pump variable frequency speed governing is carried out, ensure that user's ductwork pressure meets the requirement of user's water, city planting ductwork hydraulic pressure is higher, and the rotating speed of water pump is lower, and city planting ductwork hydraulic pressure is lower, the rotating speed of water pump is higher, when city planting ductwork pressure of supply water reach user require time, equipment quits work automatically, and the water of city planting ductwork directly supplies user by bypass pipe and uses; When city planting ductwork is cut off the water, in steady-flow tank, water level declines gradually, and when being reduced to lowest water level, the content gauge on long steady-flow tank sends stopping signal, and equipment is automatically out of service and show excessive low water level protection signal.When grid power blackout, equipment downtime, the water of city planting ductwork is directly fed to user from equipment bypass pipe.
This detailed description of the invention does not build pond, water tank, and infrastructure investment is little, environmental type, totally-enclosed, pollution-free, non-secondary pollution, water saving, utilize former pipe network water pressure, water pump operation power is little energy-conservation more, pipe network superimposed without negative pressure, variable frequency control, energy-conservation more than 50%, structure is simple, compact, space availability ratio is high, the few construction period short easy installation of floor space.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
