Example 1

Figure 3 is a basic water supply unit of the present invention comprising a first container 1, a first conduit 3 and a second conduit 4, said first conduit being connected to the upper end of the first container and the second conduit being connected to the lower end of the first container. The first container 1 is filled with two fluids of different densities, the first conduit 3 is connected to one of the fluids, and the second conduit 4 is connected to the other fluid. The basic structure of such a water supply unit can be separately provided in the system, and in the water supply unit and the water supply system described below, it is characterized by including the basic structure of such a water supply unit.

Example 2

As shown in FIG. 1, a water supply unit according to this embodiment adds a second container 2 to the first embodiment, including a first container 1, a first tube 3, and a second container that are sequentially connected to form a loop system. 2 and the second pipe 4, the first pipe 3 and the second pipe 4 are both in communication with both ends of the first container 1, and communicate with both ends of the first container 2, which are two as shown in FIG. The basic structure of the water supply unit and the structure of the pipeline connection. Taking gas and water as an example, when the first container 1 and the second container 2 are disposed at different heights, and the second pipe 4 is provided with the lifting device 5, the first pipe 3 communicates with the first container 1 and the first The gas in the second container 2, the second pipe 4 is connected Water in the first container 1 and the second container 2. Neglecting the effects of trace amounts such as gas density and water flow resistance, the pressure gauge 6 is equal to the reading of the pressure gauge 7, and the reading of the pressure gauge 8 is equal to the reading of the pressure gauge 6 plus the water level of the first container 1, the pressure gauge 9 The reading is equal to the reading of the pressure gauge 7 plus the water level of the second container 2, and is equal to the reading of the pressure gauge 8 plus the water level difference between the second container 2 and the first container 1.

If the flow rate of the inlet pipe 21 is equal to the flow rate of the outlet pipe 22, and the flow rate of the lifting device 5 is greater than the flow rate of the outlet pipe 22, water flows from the first container 1 into the second container 2 while the second container 2 is discharged. The gas is replenished to the first container 1; when the flow rate of the lifting device 5 is smaller than the flow rate of the water outlet pipe 22, the water stored in the second container 2 replenishes the shortage of the flow rate, and the gas in the first container 1 flows into the second container 2 .

It can be seen that the basic structure of a single water supply unit holds the other fluid because it is filled with one fluid; because one fluid can flow and the other fluid has a regulated volume.

Example 3

As shown in FIG. 2, the water supply unit of the embodiment adds a third container 10 to the first embodiment, including the first container 1, the first conduit 3 and the third conduit 13 that are connected, if the light weight is neglected. The effect of the density of the fluid, regardless of the relative position of the first container 1 and the third container 10, the reading of the pressure gauge 16 is equal to the reading of the pressure gauge 18.

As shown in FIG. 2, the water supply unit of the present embodiment adds a fourth container 12 to the first embodiment, including the first container 1, the connected second pipe 4, and the fourth pipe 14, because of the heavy fluid. The effect of the density is that the reading of the pressure gauge 16 is equal to the reading of the pressure gauge 17 plus the liquid level difference between the fourth container 12 and the first container 1.

In this embodiment, if the lifting device 15 is disposed on the fifth pipe 19, when the flow rate of the lifting device 15 is greater than the flow rate of the water outlet pipe 22, the third container 10 stores the surplus water amount; the flow rate of the lifting device 15 is smaller than that of the water outlet pipe 22 At the time of flow, the third container 10 replenishes the insufficient amount of water. And the pressure of the third container 10 is related to the relative positions of the first container 1 and the fourth container 12, and the adjustment volume of the third container 10 is related to the sixth duct 26 of the fourth container 12.

In the present embodiment, if the fourth duct 14 is in communication with the fifth duct 19, it is the same as in the second embodiment; if the fourth duct 14 is connected to the fifth duct 19 of the other present water supply unit, a multi-stage combination is formed.
