Description

  The present invention relates to a water tool suitable for exchanging a water meter or a stop cock.

  Conventionally, as shown in FIG. 2, a water meter M and a stop cock S are accommodated in a water meter box B. The water meter M has an expiration date of 8 years according to the Measurement Law, and the water supply department of each local government regularly replaces the water meter M.

  When the water meter M is replaced, the stop cock S is closed and the water is shut off. That is, after closing the stop cock S, the old water meter M is removed, and the new water meter M is attached there. At this time, although the old water meter M was somehow removed, the installation width of the new water meter M is less than the original size of the water meter M due to land changes and construction mistakes from the beginning. There is a case. If it is normal, some width | variety can be ensured by adjusting (shrinking) the expansion-contraction part and the elastic joint with which the water stop cock S is equipped. However, if neither adjustment is possible, that is, there is no play width, a new water meter M cannot be installed. Therefore, in the past, the pipes were forcibly shifted and new water meters M were fitted, but shifting the pipes manually to increase the width is very labor intensive and poor workability. This is particularly difficult if the worker is an elderly person.

  On the other hand, when the old water meter M is removed and the outside line or extension line is pulled and exceeds the installation width of the new water meter M in millimeters, it cannot be adjusted by the expansion / contraction function of the stop cock S, etc. It is necessary to forcibly displace the piping, and in this case, too much labor is required.

  Furthermore, when the stop cock S is obsolete and cannot be brought into a water shut-off state, it needs to be replaced from the stop cock S. Installation of the stop cock S is extremely difficult due to the water pressure.

  Accordingly, various meter units have been disclosed in order to facilitate replacement of the water meter M (see, for example, Patent Document 1 and Patent Document 2). It is considered that the water meter M can be replaced relatively easily by attaching the water meter M via the meter unit disclosed in Patent Literature 1 and Patent Literature 2.

  However, the attachment structure of the water meter M is generally a screwed structure in which a nut is screwed into a male screw provided on both sides of the water meter M. Accordingly, there is no suitable water tool when the width of the water meter M is slightly narrowed or slightly wide, and the current situation depends on human power.

  In addition, if the water meter M is attached through the meter unit disclosed in Patent Document 1 or Patent Document 2, it is considered that the water meter M can be replaced relatively easily. There are few cases where is attached. When a new meter unit is attached, it is necessary to secure a work time for attaching the meter unit, and an extra cost is required.

  Therefore, in view of the above problems, the inventor of the present application can easily adjust the mounting width and replace the water meter M even if a slight error occurs in the mounting width of the water meter M. As a result of intensive studies to provide a water tool that facilitates the replacement work of the stop cock S that is extremely difficult due to water pressure, the present invention has been achieved.

  That is, the water tool of the present invention is characterized in that a faucet plug is provided at the tip of each straight screw rod provided in the turnbuckle body.

  In the water tool of the present invention, a through hole is formed in the bottom surface of at least one of the faucet plugs.

  According to the water tool of the present invention, the water meter and the stop cock can be easily replaced without relying on human power.

  Further, in the water tool of the present invention, by forming a through hole in the bottom surface of at least one of the faucet plugs, the water pressure from the outside line can be reduced during the faucet replacement work, and the faucet replacement is performed. Work can be performed more easily.

It is a top view which shows the state which removed the water meter. It is a top view which shows the state which attached the water tool of this invention from the state of FIG. It is a top view which shows the state which removed the water meter and the stop cock. It is a top view which shows the state which attached the water tool of this invention from the state of FIG.

  Hereinafter, an embodiment of a water tool of the present invention will be described based on the drawings. Fig.1 (a) is a top view of the water tool 10 which concerns on one Embodiment of this invention, FIG.1 (b) is a right view of the water tool 10. FIG. As shown in the figure, the water supply tool 10 of this embodiment includes faucet plugs 18 and 20 at the tips 14 a and 16 a of straight screw rods 14 and 16 provided in the turnbuckle body 12.

  As shown in FIG. 1B, at least one of the faucet plugs 18 and 20 (the faucet plug 20 in the figure) has a plurality of through holes 24 formed in the bottom surface 22 thereof. It is preferable. By forming the through hole 24 in the bottom face 22 of the faucet plug 20, the water pressure from the outside line can be reduced when the stop cock S is replaced, and the replacement work of the stop cock S is facilitated. Can do. The procedure for replacing the stop cock S will be described later.

  According to the water supply tool 10 of the present embodiment configured as described above, the water meter and the stop cock can be easily replaced without relying on human power.

  Below, the procedure which replaces | exchanges the water meter M using the water tool 10 of this embodiment is demonstrated based on drawing. 2 is a plan view showing the inside of a conventional meter box B, FIG. 3 is a plan view showing a state where the water meter M is removed, and FIG. 4 is a state where the water tool 10 of this embodiment is attached from the state of FIG. FIG.

  First, the water stop cock S in the meter box B shown in FIG. And the nut which screwed the water meter M is removed and the water meter M is removed (refer FIG. 3). Here, when it is very difficult to remove the water meter M, the installation width of the new water meter M is less than the original size of the water meter M in millimeters due to land changes or construction mistakes from the beginning. there is a possibility. In this case, even if a new water meter M is to be attached, the new water meter M does not fit between the extension I side and the stop cock S.

  Therefore, as shown in FIG. 4, the water tool 10 of the present embodiment is attached to the attachment position of the water meter M. In the figure, a faucet plug 18 associated with the water tool 10 is screwed onto the extension I side, and a faucet plug 20 associated with the water tool 10 is threaded onto the stop cock S side.

  Then, the turnbuckle body 12 is turned to gradually increase the overall length of the water tool 10 so that the space between the extension I and the stop cock S is slightly wider than the width of the new water meter M. By leaving in this state for a while, the positions of the extension line I and the stop cock S are maintained in a state slightly wider than the installation width of the new water meter M, so the new water meter M is attached immediately after removing the water tool 10.

  On the other hand, when the old water meter M is removed, the distance between the extension I and the stop cock S increases due to external force or the like. For example, when the nut on the new water meter M and the extension I side is screwed, the nut of the stop cock S Even if it cannot be screwed, it can be easily replaced without relying on human power by using the water tool 10 of the present embodiment.

  That is, as shown in FIG. 4, the water meter 10 according to this embodiment is attached to the attachment position of the water meter M, and the turnbuckle body 12 is turned to gradually shorten the total length of the water tool 10. The space between I and the stop cock S is about the width of the new water meter M. By leaving in this state for a while, the positions of the extension line I and the stop cock S are maintained in a state that is about the same width as the installation width of the new water meter M. Then, the water meter M can be easily replaced by attaching a new water meter M immediately after removing the water tool 10.

  As described above, by using the water tool 10 of the present embodiment, the water meter M can be easily replaced without labor.

  Next, a procedure for replacing the stop cock S using the water tool 10 of the present embodiment will be described. If the stop cock S is damaged when the water meter M is replaced and cannot be shut off, the stop cock S needs to be replaced together with the water meter M.

  First, as shown in FIG. 5, the water meter M and the stop cock S are removed. At this time, a large amount of water is ejected from the outer line O side. Immediately, the water supply tool 10 of this embodiment is attached to the extension I side (see FIG. 6). Since the through-hole 24 is not formed in the faucet plug 18 on the extension line side according to the present embodiment, it is possible to prevent muddy water from entering the extension line side.

  Next, the stop cock S is screwed into the faucet plug 20. At this time, since the through hole 24 is formed in the bottom surface 22 of the faucet plug 20, the clean water ejected from the outer line O side can be discharged from the through hole 24 to the outside, and the pressure can be reduced. .

  When the water tool 10 of this embodiment is gradually extended in this state, the water stop cock S can be brought into close contact with the outer line O side while resisting the water pressure of clean water. Then, by fitting the nut on the outer line O side with the male screw of the water stop cock S, the water stop cock S can be easily attached to the outer line O side without being affected by water pressure.

  When the installation of the new stop cock S is completed, the water stoppage S can be shut off by closing the stop cock S, so the water tool 10 attached between the extension I and the stop cock S is removed, and a new water tap is placed at that position. By attaching the meter M, the replacement work of the stop cock S and the water meter M is completed.

  As described above, according to the water tool 10 of the present embodiment, it is possible to easily perform the operation of replacing the stop cock S, which is usually very difficult due to the water pressure of clean water.

  The water tool 10 according to one embodiment of the present invention exemplified above should not be construed as substantially limiting the technical idea of the present invention. For example, the lengths of the turnbuckle body 12 and the screw rods 14 and 16 are not particularly limited, and are appropriately selected depending on the total length of the water meter M. Further, the diameters of the faucet plugs 18 and 20 are not limited, and a nominal diameter used in a general water supply facility can be appropriately selected and applied. The present invention can be carried out without departing from the gist thereof, with appropriate improvements, changes or additions based on the inventive ideas and ideas of those skilled in the art.
