There are three water pumps 4, which are connected in parallel with the water inlet collecting pipe 9 and the water outlet collecting pipe 10.

The control cabinet 13 is provided with a PLC controller, a touch display screen, a frequency converter and a power supply, a pressure transmitter 7 on the municipal water inlet pipe 6, a flow controller 3, a negative pressure detection device 8, a water pump 4, a stabilizer The signals of the flow tank 1, the pressure transmitter 11 on the water outlet collecting pipe, the overpressure protection device 12, the upper liquid level controller and the lower liquid level controller in the steady flow tank 1 are all transmitted to the PLC controller.

The base is installed on a concrete foundation, and a shock-absorbing pad is arranged between the base and the concrete foundation.

The vacuum suppressor 2 is also equipped with activated carbon, and adopts a floating ball externally installed piston type connection, which solves the common problem that the floating ball falls into the tank body on the market.

The water inlet collecting pipe 9 and the water outlet collecting pipe 10 are both cold drawn and stretched, and the inner walls of the joints have a natural and smooth slope, which effectively reduces the noise and the loss of the water flow pipeline.

The steady flow tank 1 adopts the process of automatic welding, one-side welding and two-side forming, one-time bottoming and two-time covering process, and all welds in the tank are polished inside and outside, which greatly prolongs the service life of the steady flow tank 1 .

The operation steps and working principle of the tank-type non-negative pressure stabilizing and regulating storage water supply equipment of the utility model are as follows:

1. According to the water supply situation of the municipal pipe network and the needs of users, set a series of parameters such as municipal pressure and user pressure on the touch screen;

2. When the municipal water pressure is normal and the water volume is sufficient, the flow controller 3 is turned on, and the water pump 4 uses the municipal water pressure to relay water to achieve the purpose of energy saving.

3. When the municipal incoming water pressure drops to the minimum service pressure value set by the PLC controller, the pressure transmitter 7 installed on the municipal water inlet pipe 6 in the front section of the flow controller 3 sends the pressure signal to the PLC controller , the PLC controller closes the flow controller 3 according to the programming instruction, and at this time, an instant vacuum is generated before the inlet section of the water pump 4.

4. The vacuum suppressor 2 is opened under the action of the instantaneous vacuum, the air is reciprocally filtered through the activated carbon in the vacuum suppressor 2, and the air is purified and enters the stabilization tank 1 to achieve the effect of breaking the vacuum. At this time, the water level in the stabilization tank 1 rapidly When falling to the upper liquid level, the signal is transmitted to the PLC controller, and the flow controller 3 is opened according to the program instruction. At this time, the water pump 4 and the municipal pipe network have formed a fault layer.

5. At this time, the municipal incoming water flows into the steady flow tank 1 through its own gravity, instead of being forcibly pumped by the water pump. At the same time, the upper end of the steady flow tank 1 is used to protect the municipal pipe network. Two kinds of situations can occur in municipal water flow at this moment: the first kind is that municipal water flow is greater than demand, and the air in the steady flow tank 1 can be got rid of gradually, eliminates fault layer and reaches initial state; The second kind is that municipal water flow is less than demand, so that the liquid level in the steady flow tank 1 is gradually decreasing. When it drops to the lower liquid level, the tank-type non-negative pressure stabilizing and regulating storage water supply equipment will automatically shut down. But at this time, the municipal water supply has not been cut off, and the municipal water is still pouring water into the steady flow tank 1. When the water level rises to the upper liquid level, the water pump 4 starts automatically. How much water the user supplies without damaging the pressure of the municipal pipe network, thus achieving the purpose of protecting the municipal pipe network.

The utility model is a new generation of secondary pressurized water supply equipment that can be directly connected to the tap water pipe network without any side effects on the tap water pipe network. When the pressure of the pipe network drops to the minimum service value, the utility model It can really achieve the function of large-capacity voltage regulation and livestock adjustment (using the water flow of the pipe network to supply water to users), and it will not have any negative impact on the municipal pipe network. When the pressure of the municipal pipe network is normal, this equipment can directly use the pressure of the pipe network to provide superimposed water supply to users, which truly reflects energy saving and environmental protection. Reliable operation, convenient maintenance and many other features.

To sum up, when the water inlet pressure of the municipal pipe network can directly meet the user's requirements, the tank-type non-negative pressure stabilized pressure storage water supply equipment is in a dormant state, and the municipal pipe network directly supplies water to the user; when the municipal pipe network pressure cannot When the user's needs are met, the system will automatically wake up, and through frequency conversion control, the water supply will be superimposed on the basis of the original municipal pipe network pressure until the actual required pressure is reached.

The above is a detailed introduction of a tank-type non-negative pressure stabilized pressure storage water supply equipment provided by the embodiment of the present invention. In this paper, specific examples are used to illustrate the principle and implementation of the present invention. The above embodiments The description is only used to help understand the technical solutions disclosed in the utility model; at the same time, for those of ordinary skill in the art, according to the idea of the utility model, there will be changes in the specific implementation and application scope. As stated above, the content of this specification should not be construed as a limitation of the present utility model.
