The water supply installation with the above structure is adopted, the single-suction valve is opened when negative pressure is produced in the tank, the internal portion of the tank is communicated with the atmosphere, the water pump is pressurized to supply water, which cannot produce negative pressure to the pipe network, when the negative pressure is provided in the tank, the single-suction valve is closed, the water pump can be pressurized to supply water on the basis of the water pressure of the tap-water pipe, thereby lowering energy consumption.
Description
Technical field
The utility model relates to the supply equipment technical field, and being specifically related to a kind of pipe network does not have negative pressure and laminate pressurized watering device.
Background technology
At present, high-rise building is supplied water or, often can't satisfy user's requirement because hydraulic pressure is low or hydraulic pressure is unstable to the water supply of tap water hydraulic unstable region building.Now dual mode is taked in the solution of this problem usually.The one, on water supply pipe, directly seal in water booster system, but this method produces negative pressure to the tap water pipe network easily, influences other users on the pipe network; The 2nd, to build water-storing devices such as reservoir or water tank, and then supply water with water pump pressurization, this method can not make full use of the hydraulic pressure of tap water pipe network, wastes the energy, moreover water-storing device mostly is open containers and is easy to generate secondary water and pollutes.
The utility model content
The technical problems to be solved in the utility model is the deficiency that exists at existing water supply installation, provides a kind of hydraulic pressure that can make full use of the tap water pipe network can not cause the water supply installation of negative pressure again to pipe network.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme, and water supply installation comprises tank body and electrical control cubicles, and tank body is provided with water inlet and delivery port, water inlet links to each other with water supply pipe, and normal pressure feed pipe that is set up in parallel and pressurization feed pipe are communicated with delivery port and main-supply; The normal pressure feed pipe is provided with one way valve, and the pressurization feed pipe is provided with one way valve and water pump, and main-supply is provided with pressure sensor; Tank body is provided with pressure sensor and liquid level sensor, and water pump, pressure sensor and liquid level sensor are electrically connected with electrical control cubicles; Tank body is provided with single-suction valve, and its air inlet pipe has with atmosphere and is communicated with, and its escape pipe is communicated with tank interior.
The pipe network of employing said structure does not have negative pressure and laminates pressurized watering device, because tank body is provided with single-suction valve, do not reach when producing negative pressure in the water requirement jar single-suction valve at flow of inlet water and hydraulic pressure and open, tank interior is communicated with atmosphere, the water pump water supply of pressurizeing can not cause negative pressure to pipe network.When flow of inlet water and hydraulic pressure reached water requirement, single-suction valve was closed, and the water supply of can pressurizeing on the basis of tap water pipe network hydraulic pressure when the water pump pressurization is supplied water can cut down the consumption of energy like this.
In order to prevent that the single-suction valve air inlet port from being used by dust foreign material occlusive effects, air inlet pipe is passed tank body, is communicated with atmosphere in the tank body bottom.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, water supply installation is by tank body 1 and electrical control cubicles 2, and tank body 1 is provided with water inlet 3 and delivery port 5, and water inlet 3 links to each other with water supply pipe 4, and normal pressure feed pipe 6 that is set up in parallel and pressurization feed pipe 7 are communicated with delivery port 5 and main-supply 8; Normal pressure feed pipe 6 is provided with one way valve 9, and pressurization feed pipe 7 is provided with one way valve 9 and water pump 10, and main-supply 8 is provided with pressure sensor 11; Tank body 1 is provided with pressure sensor 11 and liquid level sensor 12, and water pump 10, pressure sensor 11 and liquid level sensor 12 are electrically connected with electrical control cubicles 2 by lead 16; Tank body 1 is provided with single-suction valve 13, and its air inlet pipe has 14 to pass tank body 1 and be communicated with atmosphere in its underpart, its escape pipe 15 and tank body 1 internal communication.
When above-mentioned water supply installation reached setting value at discharge and hydraulic pressure, when water pump was not worked or the water pump that has a power failure can not be worked, water can enter normal pressure feed pipe 6 and back down one way valve 9 through delivery port 5, enters main-supply 8, supplied water to the user realizing.When discharge and hydraulic pressure do not reach setting value, pressure sensor 11 on the tank body 1 sends signal to electrical control cubicles 2, electrical control cubicles 2 starts water pump 10 runnings and realizes supplying water, if this moment, flow of inlet water was less than the user's request amount, when producing negative pressure in the tank body 1, single-suction valve 13 is opened automatically tank body 1 inside is communicated with atmosphere, avoid the negative pressure of network of rivers generation from the beginning, the water of tank body 1 storage inside replenishes the water inlet insufficient section simultaneously, liquid level sensor 12 sends signal and stops water pump operation when liquid level is reduced to the low liquid level of setting in the tank body 1, to avoid water pump to damage because of anhydrous, when returning to high water level Deng tank body 1 interior water level, liquid level sensor 12 sends the signal enabling water pump operation, resumes water supply.Thereby the pressure sensor 11 on the main-supply 8 can detect the size of hydraulic pressure and send signal to the rotating speed of frequency converter with control of pump, can more reasonably utilize the energy.
