JP2000227378A - Method for deciding water leak position in water tube due to pouring of foreign object - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily measure the distance between the water leak position of a water tube and a cock by opening one of the cocks being provided in the water tube, by closing all of the other cocks, and by pouring a foreign object and water from an open cock port for transferring the foreign object to a water leak position. SOLUTION: A water tube 1 includes a base cock 2 and cocks 3, 4, 5, 6, 7, and 8. When a water leak position 9 exists, the cock 4 is opened, other entire cocks are closed, and a foreign object 10 is poured into the water tube 1 from the cock 4 by continuously pouring water by a pump 11. Then, the foreign object 10 is pressed toward the water leak position 9. When the foreign object 10 reaches the water leak position 9, poured water 13 is changed to leak water, the foreign object 10 remains, and the water leak position 9 is decided. The foreign object 10 is tied with a string. When the foreign object 10 is transferred from the cock 4 by pouring water by the pump 11 to reach the water leak position 9, the foreign object 10 remains, and the water leak position 9 is confirmed. The length of the cord in the tube at that time shows the distance between the water leak position 9 and the cock 4, thus securely prospecting the water leak.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention determines a water leakage position in a water pipe in order to easily measure the distance between the water leakage position of the water pipe and the faucet.

[0002]

2. Description of the Related Art Conventional water leak detection is very inaccurate and time-consuming because it attempts to detect a small sound generated by water leakage from outside.

[0003]

SUMMARY OF THE INVENTION At a leak position in a water pipe,
Make the distance measurement from the faucet easier by making a definite indication of the leak location with foreign matter.

[0004]

Means for Solving the Problems When foreign matter and water are injected from one faucet and all the other faucets are closed, the foreign matter proceeds to the water leakage position according to the water leak, and beyond that, Since the water does not advance, the position of the water leakage can be determined in the water pipe by the foreign matter.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, a water pipe 1 includes a base faucet 2 and other faucets 3, 4,.
In the case where there are a plurality of faucets, such as 5.6.7.8, and the water pipe is broken and there is a leak position 9, one of the faucets 4
Is opened, all the other faucets are closed, and the foreign substance 10 is injected into the water pipe 1 from the faucet 4 by the continuous water injection of the pump 11, and the foreign substance 10 is pushed toward the water leakage position 9 according to the amount of water leakage. When the water reaches the water leakage position, the injected water 13 leaks and does not push the foreign matter 10, so that the foreign matter 10 stops and the water leakage position 9 is determined in the water pipe. However, the foreign material 10 in this case is a size that does not come out of the water leak port.

In the case where the foreign matter 10 of claim 2 is colored water 13, when the colored water 14 is continuously injected, the colored water 14 which is a foreign matter advances toward the water leaking position 9 as described above, and thereafter the water is leaked. Since the water leaks out of the water pipe and does not proceed beyond the water leak position 9, the water leak position 9 is determined by this color difference.

[0007] In the case of claim 1, after the foreign substance 1o and water are injected from the faucet 4, the leak position is determined, and then the faucet 2.3.5.
The foreign matter 10 whose water leakage position has been determined does not come out of the faucet even when the openings 6 and 7 are opened, but the foreign matter 10 is discharged from the faucet 8 when the faucet 8 is opened. Dividing this discharge by the cross-sectional area of the water pipe gives the faucet 8
From the water leak position 9 can be calculated. Discharge volume cm ÷ Water pipe cross-sectional area cm = Distance between water leak position and faucet cm

When the foreign substance 10 is colored water 13, the distance can be calculated only when the faucet 8 is opened.
However, as an example when another faucet is opened, when the faucet 5 is opened and the ordinary water 14 is injected from the pump 11, as shown in FIG. , The arrangement and length of the colored water 13 in the water tubes of the faucet 4 and the faucet 5 can be determined. Next, when the faucet 7 is opened, the arrangement and length of the colored water 14 in the water pipe from the branch point B to the faucet 7 can be determined by the discharged water from the faucet 7 as shown in FIG. Next, when the faucet 8 is opened, as shown in FIG. 2c, the arrangement of the colored water 14 in the water pipe from the branch point C to the faucet 8 can be understood, and the water leak determining position and the faucet 8
The distance to can be calculated.

Further, the faucet 7 is opened, and the colored water 14
When the leak position determination method is performed by injecting water, the water leak can be calculated in a short distance between the faucet 7 and the faucet 8, so that a more accurate leak position can be calculated.

If the foreign matter 10 and the foreign matter in the form of colored water are simultaneously injected, the determination and calculation of the water leakage position can be easily performed.

As shown in FIG. 3, a string is attached to the foreign matter 10 according to claim 4, which is sent from the faucet 4 by the injection of the pump 11 to reach the water leakage position 9, and the foreign matter 10 stops and the water leakage position is reached. 9 is determined. The length of the cord 15 at that time indicates the distance between the water leak position 9 and the faucet 4.

[0012]

According to the present invention, the position of the water leak in the water pipe is determined by a foreign substance, so that the position of the water leak can be accurately calculated from the position of the faucet by the subsequent discharge of the water in the water pipe. The arrangement of the water pipes can be known from the calculation of the distance between the faucets by changing the drainage faucets. This ensures that water leak detection can be performed quickly.
