Description

  The present invention provides a case where the waterfall pipe used to branch the water supply pipe that leads the tap water from the water main to each home is not used due to the replacement work of the water supply pipe or the deterioration of the waterfall When installing a new saddle-equipped water faucet on the water main, cover the lower shell of the water main faucet remaining on the water main, The present invention relates to a protector for a scabbard water faucet that can install a stool with a saddle without touching the trunk and prevents leakage even if the lower trunk of the scabbard watercock is loosened. .

  Conventionally, when branching a water supply pipe that leads tap water from a water main to each home or office, an upper-form water faucet with a screw-bar-shaped stopper is integrated. (For example, refer to Patent Document 1 and Patent Document 2).

  As shown in FIG. 7, the upper-shaped water faucet 20 is screwed to the water main pipe P and is connected to the water main pipe P and is connected to the upper end portion of the lower cylinder 21. A cylindrical upper body 22 having a cylindrical branching portion 22a to which a water supply pipe (not shown) is connected, a lower body 21 and a stop top 23 screwed into the upper body 22 so as to be movable up and down, A locking nut 24 that is screwed onto the upper end of the barrel 22 to prevent the locking piece 23 from coming off; a gasket 25 that seals between the lower barrel 21 and the upper barrel 22 and between the upper barrel 22 and the locking nut 24; It is composed of

  In FIG. 7, 26 is a union socket to which a water supply pipe is connected, 27 is a cap nut for connecting the union socket 26 to the branch portion 22a of the upper trunk 22, and 28 is a union socket 26 and a branch portion 22a of the upper trunk 22. It is a gasket that seals between the two.

  By the way, a new water faucet is newly installed in another location of the water main P, such as when the water pipe replacement work or the quat faucet 20 becomes obsolete, and the water supply route goes through the new water faucet. Switching to the root is done. In recent years, as the water faucet, a water faucet with a saddle (not shown) that can be branched by unrestricted water when the water supply pipe is branched from the water main P is used.

  When the old water-type faucet 20 is no longer used due to the replacement work of the water supply pipe or the like, first, the stop top 23 located in the upper body 22 is lowered to the position of the lower body 21 with a tool (not shown). The inside of the lower trunk 21 is closed (see FIG. 8A). Next, the union socket 27 and the water supply pipe are removed from the upper body 22 by rotating the cap nut 27 in a loosening direction (see FIG. 8B). Thereafter, the upper body 22 is removed from the lower body 21 and water is stopped by a retaining piece 23 in the lower body 21, and a retaining nut 24 is screwed onto the lower body 21 to prevent the retaining body 23 from coming off. Then, the water tap 20 was buried (see FIG. 8C). In other words, the former water faucet 20 that was no longer used was left in this state, leaving the lower barrel 21 in the water main P, closing the water intake of the water main P with the stopper 23 in the lower barrel 21. .

  Then, a new water faucet with a saddle to be newly installed is installed near the lower trunk 21 of the former water faucet 20.

  However, since the lower shell 21 is screwed into the main water pipe P made of cast iron pipe, the above-described upper-shaped water faucet 20 may loosen due to secular change or the action of external force. It is very easy to remove from the tube P. As a result, it is extremely dangerous to leave the water faucet 20 as it is, which causes water leakage. In particular, when a new water faucet with a saddle is installed in the water main P, the water faucet with a saddle is likely to come into contact with the lower trunk 21 of the waterfall main water tap 20 remaining in the water main P. The lower body 21 can be easily removed from the water main P.

  In order to solve this problem, it is desirable to remove as much as possible the water tap 20 which is no longer used from the water main P.

  However, in this case, the water main P is temporarily cut off, and the lower trunk 21 of the water tap 20 is removed from the water main P, and the water intake of the water main P is closed with a water stop plug or the like. There is another problem that each home, business office, etc. temporarily shuts down.
