That is, the hole h formed in the through rod 37a communicates the inner path and the fourth region.

The inner path of the through rod 37a and the hole h communicate the third region and the fourth region isolated by the upper and lower partition plate P3 through which the through rod 37a is penetrated.

The other through-bores 37b, 37c, 37d, 37e, 37f, 37g, and 37h also communicate the space isolated by the upper and lower partition plates in the same manner.

The gas-liquid mixture existing in the regions defined by the upper and lower partition plate plates P1, P2, P3, P4 and P5 passes through the through holes 37 (37a, 37b, 37c, 37d, 37e, 37f, 37g, 37h) Through the internal path, it can be moved to another area.

The gas-liquid mixture existing in the first region may also move through the internal path of the penetrating rod 37f and be moved to the second region through the hole h formed in the penetrating rod 37f.

One end of the penetrating rod 37c is immersed in the mixture present in the first region and the length and diameter of the penetrating rod 37c are configured so that the gas layer g1 is formed at the top of the first region. The height of the gas layer g1 varies depending on the pressure of the mixture flowing into the main body 33.

The pressure of the mixture flowing into the main body 33 is usually not constant and fluctuates. The height of the gas layer g1 is automatically changed to perform the buffering function.

And gas layers g2, g3, g4 and g5 are formed at the tops of the other regions, respectively, and the pressure fluctuations are automatically changed by these gas layers.

5 is a view for explaining a leakage detection apparatus according to an embodiment of the present invention.

5, a leakage detection device 30 included in a multi-house water supply system using micro bubbles according to an embodiment of the present invention includes a main water supply line 30 for supplying water to the apartments 20 (H1, H2) Thereby detecting whether water leaks into the water line L1.

The leakage detection device 30 included in the apartment house water supply system using micro bubbles according to the embodiment of the present invention is technically improved as compared with the leakage detection devices using the conventional acoustic waves.

In general, the place where the water pipe (L) is buried is composed of various types of soil (moisture-free or little soil) or rocks. The elastic wave velocity in the soil with low humidity and the elastic wave velocity in the soil with high humidity Not only are there differences in the velocity of seismic waves in the rocky, sandy, or clay, but also the velocity of the seismic waves in the piping may vary with the dimensions of the same material, Even with dimensions, the acoustic wave velocity can vary greatly depending on the material of the pipe. Therefore, in order to estimate the correct seismic velocity, the mechanical properties and dimensions of the piping material should be given exactly. In the prior art, a method of manually inputting data such as the material and dimensions of a pipe to calculate the elastic wave velocity in the pipe, and calculating the elastic wave velocity in the pipe by a calculation formula is used. However, since not only the difficulty of obtaining accurate data of the piping already installed but also the actual piping can have various discontinuities (such as flanges, connectors, valves, branch pipes, pipe diameters, etc.) Estimation of the seismic velocity with the piping system inevitably has a lot of errors.

However, the leakage detection device 30 included in the multi-home water supply system using the micro bubble according to the embodiment of the present invention can accurately detect the leakage position without such an error. Hereinafter, the leak detection device 30 will be described in detail.

The water leakage detection device 30 includes elastic wave generation and receivers SG1, SG2 and SG3 for sensing elastic waves generated in the main water supply line 11. The elastic wave generation and receivers SG1, SG2 and SG3 can generate seismic waves themselves, and can also sense seismic waves. The elastic wave generation and receivers SG1, SG2 and SG3 are arranged for the respective regions R1, R2 and R3 of the main water supply line 11 and are connected to the main water supply line 11. [

In this embodiment, the main water supply line 11 passes through three regions (meaning a medium in which the moving speed of elastic waves are different from each other), generates acoustic waves and receivers SG1, SG2, SG3, Respectively.

Although not shown in FIG. 5, the leak detection device 30 includes a storage section for storing an acoustic wave velocity measured in each section (for each region) and a leakage position determination section for determining a position where the acoustic wave estimated by the leakage is generated . Here, the interval refers to the interval between the generation of the elastic wave and the receivers SG1, SG2, and SG3.

The leak position determining unit determines an elastic wave estimated as a leak from among the elastic waves sensed by the elastic wave generation and receivers (SG1, SG2, SG3) and estimates the leaked wave using the elastic wave velocity measured for each section stored in the storage unit The position where the elastic wave is generated is determined.

The storage unit stores the previously measured seismic velocity for each section. In the present embodiment, the storage unit can store the elastic wave movement speed in the first section (a section from the position where SG1 is installed to the position where SG2 is installed) and the second section (a section from the position where SG2 is installed to the position where SG3 is installed) have. The elastic wave velocities of the respective sections are set such that the elastic wave generation and receiver (SG1) generate arbitrary elastic waves, and the elastic wave generation and receiver (SG2) senses the elastic waves and the elastic waves generated by the receiver (SG1) The velocity of the elastic wave (elastic wave traveling from SG1 to SG2) moving in the first interval can be known. In addition, the generation of the elastic wave and the generation of the elastic wave and the sensing of the elastic wave by the receiver SG1 and the generation of the elastic wave by the receiver SG1, (Elastic wave traveling from SG2 to SG1). That is, two elastic velocities can be measured for each section.

In the similar manner, the elastic waves are determined for the remaining sections and stored in advance in the storage section.

The leak position determining unit determines the elastic waves and the seismic waves estimated by the leakage of the elastic waves sensed by the receivers (SG1, SG2, SG3). The method of determining the seismic wave estimated by the leakage may be appropriately selected by those skilled in the art among various methods known in the art. For example, after the reference waveform is stored in advance in the storage unit, the leakage position determining unit compares the elastic wave generated by the elastic wave generating unit and the reference wave with the elastic wave detected by the receivers SG1, SG2, and SG3, It is possible to determine the seismic wave estimated as a leak.

The leaked-position determining unit, when determining an elastic wave estimated as a leak, determines in what section such elastic wave is generated, that is, the elastic wave generating period is selected. Then, an elastic wave generation position estimated by the leakage is determined by using the elastic wave velocity (stored in the storage unit) corresponding to the selected elastic wave generation period.

The leakage position determining section can be performed by the following operation when selecting the elastic wave generating section. That is, the leak position determining unit selects the candidate section based on the intensity of the elastic wave estimated as the leak (for example, selects the elastic wave generated by first receiving the elastic wave estimated as leakage and the candidate section based on the receiver) The selected candidate section is verified. If the candidate section is valid, the candidate section is selected as the elastic wave generation section.
