Description

An intelligent water supply device

[technical field]

The utility model relates to the technical field of water supply equipment, in particular to an intelligent water supply equipment.

[Background technique]

In recent years, emerging water supply equipment directly uses the municipal pipe network as the water source. Due to the cancellation of the traditional reservoir, the entire pipe network system is closed from the municipal water inlet pipe network to the outlet of the water supply equipment to the user, and based on the municipal water pressure. Pressurized water supply, how much to make up for the difference, has two major advantages of sanitation and energy saving, but there are still some problems in the current product: on the one hand, the water source buffer tank that is currently matched with the product is a pure water storage tank, only when negative pressure is generated in the tank, The volume of water in the tank can be effectively used to compensate for the lack of municipal water supply. At this time, the inlet of the water pump is at zero pressure, so the head of the supporting water pump is required to be high. The head of the pump must meet the requirements from zero pressure to the least utilized by the user The pressure of the water point, thus limiting the overall energy saving effect of the equipment. Moreover, the volume of the buffer tank is limited, and it is generally difficult to buffer the peak water consumption contradiction of users, and the reliability of water use is poor. On the other hand, in order to retain the function of stopping and maintaining pressure, the current product also needs to install a pressure-stabilizing air tank at the equipment outlet, which will cause the equipment to be bulky, occupy a large building area, and the structural design of the equipment is also difficult to handle.

[Content of the invention]

The task of the utility model overcomes the deficiencies of the prior art, and provides a kind of intelligent water supply equipment, which is a composite water supply equipment with tap water directly supplied and a water tank as a backup water source. According to different water supply conditions, by controlling the switch of the valve, it is possible to select whether each water pump is supplied by tap water or a water tank, so as to achieve the purpose of energy saving.

The utility model adopts the following technical scheme: an intelligent water supply equipment, including a water pump unit, a valve, a pipeline, a pressure sensor, and an electric control cabinet. The water inlet of the water pump is connected to the tap water by a pipeline, and the water is directly supplied by the tap water; the water inlet of at least one water tank supply pump is connected to the water outlet of the water tank by a pipeline, and the water tank is used as a backup water source for water supply.

The water inlet pipelines of the tap water supply pump and the water tank water supply pump are connected by pipelines and valves.

The valve adopts manual valve or electric valve.

The beneficial effect of the utility model is that it is beneficial to the structural design of the equipment, effectively reduces the volume of the equipment, saves the construction area, and reduces the cost. Users use water, which greatly improves the reliability of water supply compared with traditional stacked water supply equipment.

[Description of drawings]

Fig. 1 is a schematic diagram of pipeline connection of the present invention.

See Figure 1, 1 is the water tank, 2 is the hydraulic control valve, 3 is the water inlet of the water tank, 4 is the inlet pressure sensor, 5 is the valve I, 6 is the valve II, 7 is the valve III, 8 is the valve IV, and 9 is the pump I , 10 is the pump II, 11 is the pump III, 12 is the control cabinet, and 13 is the outlet pressure sensor.

[specific example]

The utility model is described in detail below in conjunction with accompanying drawings and specific embodiments.

As shown in Figure 1, the water pump unit is equipped with 3 water pumps, of which pump I9 and pump II10 are directly supplied by tap water, pump III11 is supplied by the water tank as a backup water source, and the water inlet pipes of pump I9, pump II10 and pump III11 are respectively equipped with valve I5 , valve II6 and valve III7, the water inlet pipelines of pump II10 and pump III11 are connected with pipeline and valve IV8, and the control cabinet 12 controls the inlet pressure sensor 4, outlet pressure sensor 13, pump I9, pump II10 and pump III11.

Three pumps can be used for two purposes and one for standby, or three-purpose working mode. The number of water pumps supplied by tap water or water tanks can be one or more.

When the tap water is used at the peak of the user, the flow rate can meet the user's water consumption. Valve IV is closed, valve I, valve II and valve III are fully open, and pump I and pump II are pressurized to supply water from tap water (two uses and one backup); pump III is pressurized to supply water from the water tank (three uses); make full use of the original pressure of tap water , to achieve the purpose of energy saving.

When the tap water supply is used at the user's peak, the flow rate cannot meet the user's water consumption. Valve II is closed and valves I, III and IV are fully open. Pressurized by pump I from tap water. Pump II or pump III pressurizes water supply from the water tank (two uses and one standby); both pumps II and pump III pressurize water supply from the water tank (three uses). The above working conditions can be restored during non-peak water consumption, which not only makes full use of the original pressure of tap water, but also achieves the purpose of energy saving. It can also ensure the user's water consumption during the peak water consumption, which greatly improves the reliability of water supply compared with traditional stacked water supply equipment.

When pump I and pump II fail, valve III is closed, valve I, valve II and valve IV are fully opened, and pump III can supply tap water. Valve I, valve II, valve III and valve IV can be manual valves or electric valves.
