Detailed Description
Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.
As shown in fig. 1, the structural composition of the non-negative pressure intelligent water supply equipment is shown. The core of the device is a main pressure-stabilizing tank 1 and an auxiliary tank 2. The working principle of the pressure stabilizing main tank 1 is the same as that of the existing pressure stabilizer, water from a water supply company enters the pressure stabilizing main tank 1 through a main tank water inlet valve 11 and a main tank water inlet filter 12, and a main water pump 13 is arranged at a water outlet to pressurize tap water for supplying water. The vacuum suppressor 14 ensures that no negative pressure occurs in the surge tank 1 when the primary water supply is stopped. The main tank level gauge 15 monitors the water level and the system gives an early warning or shuts down when the water level is low.
The main water pump 13 is shown as one, more than one main water pump can be arranged according to the requirement, a one-way valve is arranged behind the main water pump to supply water to a main pipeline of the building, and the main pipeline is provided with a pressure gauge and a flow meter to be connected with the control cabinet 3. The main water pump is a variable frequency water pump, and the rotating speed is adjusted according to the set value of the secondary water supply pressure.
Because the power of the main pump is large, the water demand of the building is small in the water use valley period (such as at night), the main pump is used for maintaining the water supply pressure and flow and consuming high energy, and the auxiliary pump and the storage tank are considered to be used for supplying water in the water use valley period.
As shown in fig. 1, the sub-tank 2 of the present embodiment is provided at the top level for supplying water during the water-using valley period. The auxiliary tank 2 is communicated with the pressure stabilizing main tank 1 through a main and auxiliary tank connecting pipe. The first main and auxiliary tank connecting pipe 21 is provided with a one-way valve which can be communicated with the auxiliary tank in a one-way manner; the second main and auxiliary tank connecting pipe 22 is provided with a check valve, which can conduct the flow direction of the water supply outlet to the pressure-stabilizing main tank in one way.
The auxiliary pump 23 is provided at the first main and auxiliary tank connection pipe 21 at the top level for pumping the water in the pressure-stabilizing main tank into the auxiliary tank 2, and the water stored in the auxiliary tank 2 is supplied to the user at the water valley period by using the water pressure provided by gravity. And a one-way valve is arranged between the auxiliary tank and the auxiliary pump and is communicated with the auxiliary tank in a one-way.
And the top of the auxiliary tank is provided with a one-way air inlet and a one-way air outlet 24, and the one-way air inlet 25 and the one-way air outlet are both provided with one-way valves to be electrically connected with the control cabinet. The one-way air inlet 25 is provided with an air filter.
The auxiliary pump and the container for supplying water at night are moved from the bottom layer to the top layer, so that the auxiliary pump does not need to be operated all the time, and water pressure is supplied by gravity. Because the air pressure tank is adopted, the tank body not only needs to store a certain amount of high-pressure gas, but also needs to store a certain amount of water, the volume is larger, and the common container is adopted to replace the air pressure tank and only needs to store water, so that the space can be reduced, and the material requirement of the container can be reduced.
When the auxiliary tank is used for supplying water, the water level is reduced slightly relative to the height of the supplied water, and the pressure of the air pressure tank is obviously reduced along with the expansion of the gas, so that the auxiliary tank is used for supplying water at night, and the water pressure is more stable.
The second main and auxiliary tank connecting pipe is provided with a one-way valve, the flow direction of the water supply outlet of the pressure stabilizing main tank is conducted in a one-way mode, water is supplied through the water supply pipeline of the pressure stabilizing main tank instead of supplying water to the water supply pipeline from the top, a plurality of pipelines are avoided, and the cost is saved.
Fig. 2 shows the connection relationship of the control modules. The control cabinet is connected with a main water pump, a main tank water level meter, a main tank water inlet valve, an auxiliary water pump, an auxiliary tank water level meter, check valves and pressure gauges, and the control cabinet is connected with a control center.
Operation of the water supply equipment in the water trough period:
the main water pump 13 stops running, the auxiliary pump 23 pumps water to the auxiliary tank 2, the one-way air outlet 24 exhausts the air, the auxiliary pump 23 stops after the set water level is reached, the one-way air inlet 25 can intake the air, and the gravity of the water provides water pressure for water use at night. When the water level is lowered to a certain extent, the auxiliary pump 23 is turned on.
The mode that the auxiliary pump and the air pressure tank are arranged on the bottom layer in the existing scheme is changed into the mode that the auxiliary pump and the air pressure tank are arranged on the top layer; and the mode of providing pressure by the air pressure tank is changed into the mode of providing pressure mainly by gravity. Therefore, the auxiliary pump can be prevented from continuously operating, and an air pressure tank is not required to be arranged, so that the equipment cost is reduced and the space is saved.
And the control center is connected with the control cabinet and records the action of the auxiliary pump and the historical data of the auxiliary tank water level meter. The analysis is carried out through historical data, the setting of the water level of the stored water is facilitated, and the design of the specification of the auxiliary tank of the later project is facilitated, so that energy is saved, and the design is more reasonable.
In this specification, the water supply during the water trough period is sometimes referred to as night water supply.
With respect to the pressure-stabilizing main tank and the sub-tank, the essence thereof is that the additional functional components of the container, and containers of other shapes, such as a box body, are equivalent to the "tank" used in this application.
