Abstract
The utility model discloses a multi-variable fuzzy control pipe network non-negative pressure water supply device, which comprises a steady flow water storage tank, wherein the water inlet orifice of the steady flow water storage tank is connected with a tap water pipe and the water outlet orifice is connected with an user water pipe via a water pump water supply pipe unit; the steady flow water storage tank is mounted with a pressure sensor and an intelligent negative pressure eliminator; a bypass branch is provided between the tap water pipe and the user water pipe; the bypass branch is provided with a check valve; the user water pipe is mounted with a remote pressure sensor and a flow meter; the pressure sensor, the remote pressure sensor and the flow meter are electrically connected with an electric control box. The utility model resolves the instable water pressure problem caused by water consumption valley and peak times, and can satisfy user's demands at tap water pipe and can save water and electricity resource.
Description
Technical field
The utility model relates to the supply equipment field, specifically is a kind of Multivariable Fuzzy control pipe network non-negative pressure water-supply installation that is used for the water supply pipe system.
Background technology
At present, along with the progressively development in city, urban water consumption increases, and original water supply pipe pressure occurs not enough.In this case, traditional way is a reservoir in the middle of building, and is pressurised into each subscriber unit by non-negative pressure water-supply installation or secondary and supplies water.Non-negative pressure water-supply installation mostly adopts the mode of series connection current stabilization water tank on the running water pipe, and under any circumstance, the current stabilization water tank is all in running order, causes the waste of the energy easily; Second pressure water supply, wherein pressure in the service pipe and flow cannot be regulated in real time, can not solve the pressure balance problem of water use peak phase and low peak period.
The utility model content
The technical problems to be solved in the utility model provides a kind of energy-conservation and regulate the Multivariable Fuzzy control pipe network non-negative pressure water-supply installation of service pipe pressure and flow in real time.
For solving the problems of the technologies described above, the Multivariable Fuzzy control pipe network non-negative pressure water-supply installation that is provided, comprise the current stabilization water tank, the water inlet pipe mouth of current stabilization water tank is connected with running water pipe, the effluent pipe mouth of current stabilization water tank is connected with service pipe by water pump feed pipe group, it is characterized in that: be provided with the bypass branch road between running water pipe and the service pipe, the bypass branch road is provided with flap valve, distal pressure sensor and flow meter are installed on the described service pipe, and described distal pressure sensor and flow meter all are electrically connected with electric control box.
Be provided with liquid level sensor in the described current stabilization water tank, liquid level sensor is connected with electric control box.
After adopting said structure, distal pressure sensor and flow meter that service pipe is provided with import signal into electric control box at any time, electric control box will be controlled according to the bivariate of water flow and pressure, thereby make service pipe lead to the pressure all-the-time stable of a unit users by the variable frequency adjustment of water pump.When the pressure of running water pipe was enough to satisfy unit users, the current stabilization water tank was in off position, directly supplied water for each subscriber unit by the bypass branch road; When water use peak, utilize water pump to increase the pressure and the flow of outlet pipe; When the water ebb, reduce pressure of supply water automatically.The utility model has not only solved the unstable phenomenon of the user's hydraulic pressure that water low peak period and peak period brings, and when running water pipe can be met consumers' demand, but the conserve water electric resources.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
Multivariable Fuzzy control pipe network non-negative pressure water-supply installation as shown in Figure 1, comprise current stabilization water tank 3, the water inlet pipe mouth of current stabilization water tank 3 is connected with running water pipe 1, the effluent pipe mouth of current stabilization water tank 3 is connected with service pipe 2 by water pump feed pipe group, water pump feed pipe group comprises two groups of water pumps 7 in parallel and flap valve, the top of current stabilization water tank 3 is equipped with pressure sensor 5 and intelligent negative pressure arrester 6, be provided with liquid level sensor 11 in the inner chamber of current stabilization water tank 3, be provided with bypass branch road 4 between running water pipe 1 and the service pipe 2, bypass branch road 4 is provided with flap valve 12, distal pressure sensor 8 and flow meter 9 are installed on the service pipe 2, the terminal of service pipe 2 is each subscriber unit 13, described pressure sensor 5, water pump 7, liquid level sensor 11, distal pressure sensor 8, flow meter 9 all is electrically connected with electric control box.
Computer transduce variable quantity and pressure multivariable fuzzy control technology and no negative pressure treatment technology that the utility model adopts are directly connected with the tap water pipe network.Liquid level sensor 11 and pressure sensor 5 import signal in the electric control box Control System of Microcomputer, intelligence negative pressure arrester 6 can guarantee the stable of pressure in the current stabilization water tank 3, at first according to the actual conditions analysis of user's pipe network, by flow meter 9 with water flow, by distal pressure sensor 8 with the calculation of pressure of service pipe 2 and input channel characteristic curve to Control System of Microcomputer, during the equipment operation, real-time signal with flow meter 9 and distal pressure sensor 8 is transferred to the Control System of Microcomputer in the electric control box 10, determine service pipe 2 pressure by pipeline characteristic curve and current actual pressure, Control System of Microcomputer control variable frequency pump 7, thereby the flow of control service pipe 2 and the demand that pressure satisfies each subscriber unit 13.Whole Control System of Microcomputer can be monitored real-time control in real time, reaches the effect of big ground energy conservation.
