Description

Partial pressure water supply device and its partial pressure water supply method

The present invention relates to a water supply system, and more particularly to a partial pressure water supply device and a partial pressure water supply method therefor. Background technique

The existing type of water supply device supplies water to users through the water network as a water source, and the water network pressure can usually only be used by users of about six floors. When the pressure of the water network cannot be used by the high-end users with higher ground conditions, the water is usually used to pressurize the water of the water source. After the water is pressurized by the water pump, the water flow is more urgent and the water resources are wasted as the terrain rises. The water pressure of the high-end user terminal is small, which makes the water pressure of the high-end user end and the water pressure of the low-end user end greatly different. It is unable to satisfy the relatively balanced position of the higher ground and the lower pressure of the lower ground. There is also a type of water supply device that stores water through a container tank, and then uses an air compressor instead of a water pump to pressurize the water in the container tank. Whether using an air compressor or a water pump increases the cost of the device and wastes the air compressor. Or the energy consumed by the pump.

For example, the Chinese Patent Bulletin No.: CN2432256Y, a water supply device announced on May 30, 2001, consists of a water pump, a faucet, a switch that controls the opening and closing of the water pump, and a control circuit thereof. The contact of the switch and the valve stem of the faucet In surface contact, the faucet valve stem has a curved surface with a gradual radius. The contact reciprocates or retracts as the wide rod rotates up and down, and the switch is opened or closed to control the opening and closing of the water pump. The water supply device in this patent is passed The water pump is started to pressurize the water supply. However, after the water pump is pressurized, the water pressure is higher at the lower position. As the terrain increases, the water pressure decreases. It is impossible to ensure that the water supply pressure is higher in the position with higher terrain and lower position. Balance; and the pressure in the lower position is too high, the water is too fast, the water is wasted, and the pump starts to consume a lot of other energy, such as electricity, environmental protection, and waste of energy. Disclosure of invention

The invention mainly aims at the problem that the water supply pressure of the existing water supply device is unbalanced, the water pressure of the low-end user end is large, the water resource is wasted, and the water pressure of the high-end user end and the water pressure of the low-end user end are greatly different, and the like, and the problem can be effectively provided. A partial pressure water supply device for dividing the water pressure of the low-level user end and the high-end user end, and the water pressure of the high-end user end and the water pressure of the low-level user end are relatively balanced, and energy-saving and water-saving, and a partial pressure water supply method thereof.

The object of the present invention is mainly achieved by the following scheme: a partial pressure water supply device comprising at least one set of sealed container cans, the sealed container can including a low-level sealed can connected to a low-end user end and at least a high-position sealed can connected to the high-end user end and having a height difference between each other, the high-position sealed can and the low-position sealed can are communicated through an air-guiding pipe, and the inlet end of the high-position sealed can and the lower sealed can The water end is connected to the water source, the water inlet end of the low level sealed tank is provided with a first valve, the water inlet end of the high level sealed tank is provided with a second valve, and the water outlet end of the high level sealed tank is provided with a check valve. When the sealed container tank group is a single group and the high-position sealed tank is one, the low-level sealed tank is set at a lower position, and the high-position sealed tank is set on the topography according to the difference of the high-end user end ground and the high-end user end water demand. Higher position.

As the water level of the high sealed can and the low sealed can rise, the gas chamber of the high sealed can and the low sealed can is reduced, and the gas in the sealed canister is squeezed to make the gas pressure between the high sealed can and the low sealed can. Increase. When the gas pressure between the high sealed can and the low sealed can is balanced with the water pressure at the inlet end of the high sealed can, the second valve is closed. The water source pressure is continuously applied to the inlet end of the low-level sealed tank and continues to fill the water in the low-level sealed tank. As the water level in the low-level sealed tank rises, the gas that is in equilibrium with the inlet end pressure of the low-level sealed tank enters the air duct. The high-position sealed canister and the gas pressure is applied to the water body in the high-level sealed can, so that the pressure at the outlet end of the high-position sealed canister at a high position is relatively balanced with the pressure at the inlet end of the low-level sealed can, and the high-position sealed can can be directed to the high-end user end.

When the user of the low-end user is using water, the water level of the low-level sealed can is lowered, and the gas pressure between the high-sealed can and the low-sealed can is reduced. When the gas pressure between the high sealed can and the low sealed can is less than the inlet pressure of the high sealed can, the water source fills the high sealed can through the second valve. As the water level in the high sealed tank rises, the gas in the high sealed tank enters the low sealed tank from the air duct, and the gas pressure is applied to the water in the low sealed tank. The outlet pressure of the low-level sealed canister can supply water to the lower user end. At this time, the outlet pressure of the low sealed can is balanced with the gas pressure, and both are less than the pressure of the water source, but sufficient to supply water to the lower user end.

As shown in Figures 1 and 2, a partial pressure water supply device includes a set of sealed container cans, and the sealed container can includes a high sealed can 1 and a low sealed can 2 . The inside of the lower sealed can 2 and the high sealed can 1 are each provided with a diaphragm 11 as a water chamber for storing water, and a portion between the low sealed can 2, the can of the high sealed can 1 and the diaphragm 11 For the air chamber, the air chamber of the high sealed can 1 and the air chamber of the low sealed can 2 are electrically connected. Both ends of the air guiding tube 18 are electrically connected to the diaphragms in the high-level sealed can 1 and the lower sealed can 2, respectively. An inflation hole 10 is attached to the top end of the lower sealed can 2 . The water inlets of the high sealed can 1 and the lower sealed can 2 are connected to the water source 3, and the water source 3 can also be connected to the neutral user terminal 5 through a three-way joint. The outlet end of the lower sealed can 2 is connected to the lower user end 4, and the high sealed can 1 is connected to the upper user terminal 6. A first valve 7 is connected between the water inlet end of the lower sealed can 2 and the water source 3, and the water inlet and water cut of the lower sealed can 2 are controlled by the first valve port. A second valve 8 is connected between the water inlet end of the high-position sealed can 2 and the water source 3, and the water inlet and water cut of the high-level sealed can 1 are controlled by the second valve. A unidirectional width 9 is connected between the water outlet end of the high level sealed can 2 and the upper user end 6.

As shown in FIG. 2, as the water level of the high sealed can 1 and the lower sealed can 2 rises, the gas chambers of the high sealed can 1 and the low sealed can 2 are reduced, and the gas in the sealed canister group is squeezed to seal the high position. The gas pressure between the tank 1 and the lower sealed can 2 is increased. A pressure gauge can be installed on the sealed container can set to detect the magnitude of the gas pressure between the high sealed can 1 and the low sealed can 2. When the gas pressure between the high sealed can 1 and the lower sealed can 2 is balanced with the water pressure at the inlet end of the high sealed can 1, the second valve 8 is closed. As shown in Fig. 3, the water source pressure is continuously applied to the inlet end of the low-level sealed can 2 and continues to be filled into the lower sealed can 2, as the water level in the lower sealed can 2 rises, and the inlet of the lower sealed can 2 The pressure-balanced gas enters through the air duct 18 The high-position sealed can 1 and the gas pressure is applied to the water body in the high-pressure sealed can 1, so that the pressure at the water outlet end of the high-position sealed can 1 at a high position is relatively balanced with the pressure at the water inlet end of the low-level sealed can 2, and the high-position sealed can 1 is It is possible to supply water to the high-end customer terminal 6.

As shown in Fig. 4, when the water level of the lower sealed can 2 rises to a certain value or the water level of the high sealed can 1 drops to a certain value, the first wide door 7 is closed and the second wide door 8 is opened. When the user of the lower user terminal 4 is in use of water, the water level of the lower sealed can 2 is lowered, and the gas pressure between the high sealed can 1 and the lower sealed can 2 is reduced. When the gas pressure between the high sealed can 1 and the lower sealed can 2 is less than the inlet pressure of the high sealed can 1, the water source 3 is filled with water into the high sealed can 1 through the second valve 8, as shown in FIG. As the water level in the high sealed can 1 rises, the gas in the high sealed can 1 enters the lower sealed can 2 from the air guiding tube 18, and the gas pressure is applied to the water in the lower sealed can 2, so that the low position is sealed at a low position. The outlet end pressure of the tank 2 can supply water to the lower customer end 4. At this time, the outlet pressure of the lower sealed can 2 is balanced with the gas pressure, and both are smaller than the pressure of the water source 3, but sufficient to supply water to the lower user terminal 4. It is avoided that the water pressure of the low-end client terminal 4 is too large, the water flow is too fast, and the water source is saved. By controlling the water supply 3 to the water supply in the high sealed can 1 and the low sealed can 2, the gas pressure between the high sealed can 1 and the low sealed can 2 is changed, and the high sealed can 1 and the low sealed can 2 are controlled by different gas pressures. The water pressure is effective to save energy. Make high client 6 and low client 4 and the water pressure of the median client 5 is relatively balanced, and water resources are saved.
