Description

[Detailed Description of the Invention] The present invention relates to a water pipe leakage measuring device that quantitatively and directly measures the amount of water leaking from a water pipe.

Most of the leakage in water pipes occurs from the straight pipe section 7A shown in Figure 1a, but it also occurs from the joints.

The joint part of the water pipe is the socket 1 shown in Figure 1b.
A straight pipe joint structure 2 using a straight pipe part, and a T-branch joint structure 4 using a T-shape joint 3 shown in FIG.
There is a joint structure 6 for the bent part using the elbow 5 shown in FIG.
C, 7D, etc., but it also occurs when the socket 1, T-shaped joint 3, or elbow 5 is damaged, or when any part of the pipe portions 7B, 7C, and 7D is cracked or corroded.

Water leaks need to be repaired promptly, but for reasons such as post-processing and bill processing, it is sometimes necessary to measure the amount of water leakage as accurately as possible.

In conventional methods of measuring the amount of water leakage, the leakage location is exposed and then the state of the water leakage is determined empirically by the worker's visual inspection, so there are large individual differences.

Therefore, in some areas, water leakage is measured using a cup using a rubber hose, or the water pipe is cut about 20cm in front of and behind the leakage point and measured indirectly with a Woltmann flow meter.
Both of these methods were time-consuming and could not be expected to accurately measure the amount of water leakage, so there was a need for a leakage measuring device for water pipes that could directly and quantitatively measure the amount of water leakage.

In view of this, this proposal provides a water pipe water leakage measurement device that meets the above-mentioned request.The main body and lid have a required depth that can be opened and closed, and a non-water permeable A recessed portion is opened in the center of each of the molded gaskets on the main body side and the lid body side, where they overlap each other, and the leakage portion of the water pipe can be freely accommodated therein. , communicating with this recess, opening grooves having a semicircular cross-sectional shape on the outer surfaces of the main body and the lid into which the pipe portion of the water pipe can be freely inserted, and further providing an outlet communicating with the recess. A box for covering a water leak, a cylindrical measuring instrument having a vertical slit in the wall and housing a float that can be slid up and down in close contact therein, and having an outlet at the bottom, and the box. It consists of a hose that connects the water outlet of the meter with the water intake of the meter.

Next, embodiments of the present device will be described with reference to the drawings.

Fig. 4 is a partially cut-out front view of the embodiment of the proposed device, Fig. 5 is a plan view of the main body, and Fig. 6 is a partially cutaway box for covering the water leakage part. are shown in side view.

The present device consists of a box 10 for covering water leaks, which is formed by attaching a lid 9 to the main body 8 so as to be openable and closable, and a measuring device 12 connected via a hose 11. Each has a non-water permeable plastic molded gasket 1 inside.
3 is stored.

Molded packing 1 stored in the main body 8 and lid 9
3 shall be in close contact with each other when the main body 8 and lid body 9 are closed, and the water pipe joint portion 2,
4 or 6, there is a recess 14 of a size and shape that can accommodate the two parts divided in a plane including the axis, and a part communicates with this recess 14, and the other end is
Grooves 15A, 15B, and 15C are opened on the outer surface of the main body 8 or the lid 9, respectively, and each has a semicircular cross-sectional shape and into which a pipe portion of a water supply line can be inserted.

Each of the grooves 15A, 15B, and 15C is sized and shaped so that one half of the pipe portions 7A, 7B, and 7C of the water pipe line divided into two along a plane including the axes can be fitted therein.

On the other hand, the grooves 15A, 15B, 15C have a seventh groove.
One half of the blind cover piece 16 made of plastic material (for example, semi-hard rubber, etc.) shown in the plan view in the figure and in the side view in FIG. Grooves 17, 17 are formed by fitting.

The main body 8 and the lid 9 are connected by a hinge 18 so as to be freely openable and closable, and can be kept closed by latches 19A and 19B. good.

The box 10 in this embodiment has an outlet 20 in the center of the lid 9 that communicates with the recess 14.

A water intake port 21 that opens downward is formed at the bottom of the measuring device 12, and annular grooves 22 and 23 are provided in the outlet port 20 and the water intake port 21, respectively, into which the ends of the hose 11 can be tightly fitted. There is.

Note that the outlet 20 formed on the lid 9 may be formed on the main body side.

The measuring instrument 12 has a straight cylindrical shape, and has a hollow float 24 of a predetermined weight housed therein so as to be able to move up and down closely, and a vertical slit 25 is formed in the wall portion 12A.

The width of the slit 25 is determined experimentally,
When the tap water at a predetermined pressure pushes up the float 24 and flows down to the outside, the dimensions are set such that the flow rate reaches the value indicated by the scale 27 indicated by the indicator line 26 provided at the upper and lower middle portions of the float 24. There is.

In this embodiment, the scale 27 and the slit 25 are
Plate 28 attached to wall 12A of measuring instrument 12
A slit 25 is formed inside a size window hole 29 formed in the wall portion 12A, so that the slit width and scale can be changed.

Note that during measurement, the measuring instrument 12 is kept upright and stable. In addition, the hose 11 is made of a soft material and is designed to be larger than the diameter of the waterway to prevent the occurrence of turbulent flow.

Since this project has the above-mentioned configuration, after exposing the water leakage point of the water pipe, the box 10 for covering the water leakage point is placed.
The main body 8 and the lid 9 are opened, and the lower half of the leaking straight pipe and the joint structures 2, 4, and 6 are inserted into the recess 14 of the main body 8, and the upper half is inserted into the lid 9. In the case of the joint structure 2, the pipe part 7B of the water pipe is placed in the groove 15A, and the pipe part 7B of the water pipe is placed in the groove 15A.
The pipe section 7C of the water pipe will be stored in B,
The groove 15C remains open.

In the case of the joint structure 4, the tube portion 7B is placed in the groove 15A, the tube portion 7C is placed in the groove 15B, and the tube portion 7 is placed in the groove 15C.
D are stored respectively (see Fig. 10).

In addition, in the case of the joint structure 6, the pipe portion 7B is placed in the groove 15A.
However, the tube portion 7D is further accommodated in the groove 15C, and the groove 1
5B remains open.

Therefore, in order to close the groove that remains open, for example 15C when the joint structure 2 is housed in the recess 14, the flanges 16A, 16A of the blind cover piece 16 are fitted into the grooves 17, 17. The piece 16 fits into the groove which remains open.

When the joint structure 2 is housed in the recess 14 in this manner and the main body 8 and the lid 9 are closed, leakage water fills the recess 14 which has become a closed space.

The leakage water filling the recess 14 will eventually reach the outlet 20,
It enters the measuring instrument 12, which is supported upright by a worker on the ground, through the hose 11 and enters the float 24.
It flows out from the slit 25 while pushing up.

At this time, if the amount of water leakage is large, the float 24 rises to a high level.

An indicator line 26 is provided on the float 24, and the amount of water leakage can be determined by reading the numerical value on the scale 27 indicated by the indicator line 26.

As is clear from the above explanation, the present device has an excellent advantage of being able to easily and accurately measure the amount of water leakage, which is normally determined by visual inspection by workers, quantitatively and directly, regardless of individual differences. It has the following.
