64 is magnetically attached to the engaging step portion 216 of the stopper body 21 to stop the water stopper 2.
Hold.

Then, as shown in FIGS. 6 and 7, the outer peripheral screw 34 of the upper end mounting cylinder 33 of the water diversion valve body 3 from which the punching device is removed.
Then, the screw 41 at the lower end is aligned and screwed with the rotating handle 43 to fix the stopper device 5, and after the closed water diversion valve body 30 is opened, the handle 55 is pushed down to lower the elevating bar 52 and stop. The water faucet 2 is passed through the diversion valve body 3 and the standing cylinder 10
Then, the handle 55 is rotated to rotate the elevating bar 52 to screw the outer peripheral threaded portion 212 of the columnar main body 210 onto the inner peripheral threaded portion 11 of the standing cylinder 10 to attach the water stopcock 2. As a result, the large-diameter round seal ring 222 having a round vertical cross-section, which slightly protrudes from the outer periphery of the gasket 22 of the water stopcock 2, is crushed and pressure-bonded to the inner periphery of the standing cylinder 10 to be sealed. Further, the gasket 22 is in a state of being inserted into the water blocking bag insertion hole Aa.

Then, by pulling up the handle 55, the water stopcock 2 is removed from the elevating bar 52, the adapter 4 is removed from the water diversion valve body 3, and the stoppering device 5 is removed. Further, the water diversion valve body 3 is removed from the standing cylinder 10, and in this state,
The back portion of the water stopcock 2 is exposed, and by further tightening the nut 25, the presser member 23 is sent upward via the bolt 24 and the gasket 22 between the stopper body 21 and the main body 21.
Is bulged and deformed laterally, and is pressed against the inner peripheral surface of the bag insertion hole Aa to close it.

As shown in FIG. 9, the seal ring 222 on the outer periphery of the upper end of the gasket 22 and the inner periphery of the upright tube 10 and the bag insertion hole Aa are doubly sealed by the lateral bulging deformation of the gasket 22 to stop water. The effect is good, and finally, as shown in FIG. 8, the lid 8 accommodating the packing 81 is attached to the upper end of the standing cylinder 10 and the screw portion 82 of the inner periphery thereof is attached to the outer peripheral screw portion 12 of the standing cylinder 10. It may be screwed and fixed.

Although this embodiment has the above-mentioned configuration, the present invention is not limited to this. For example, the shape and structure of the saddle fixed to the pipe body and the standing cylinder connected to the saddle are not limited, and the structure of the water diversion valve body that is attached to and detached from the outer peripheral thread portion of the standing cylinder is not limited. Further, the stoppering device may be provided with an elevating bar that can rotate and ascend and descend, and can hold a water stopcock at the lower end thereof, and the rotating means of the elevating bar and the holding means for the water stopcock are also arbitrary. Furthermore, a configuration in which the stopper device is attached to and detached from the upper end portion of the water diversion valve body is also appropriate. The structure of the water stopcock is not limited.

Further, the structure of the water stopcock of the present invention is not limited, and the shape of the stopper main body, the gasket, and the pressing member arranged on the lower surface of the gasket are appropriate.

[0022]

According to the first aspect of the present invention, the water stopcock can be safely and easily screwed to the standing cylinder of the saddle, the bag insertion hole can be closed, and the diversion valve body can be removed for reuse. It can be achieved. According to the second aspect, it is possible to easily screw the water stopcock held by the elevating bar to the standing cylinder. According to the third aspect of the present invention, it is possible to easily hold the water stopcock on the lifting bar and remove it.

According to a fourth aspect of the present invention, a large-diameter round seal ring having a vertical cross-section, which slightly protrudes from the outer circumference of the gasket, is crushed and crimped to the inner circumference of the upright cylinder to be sealed, and the nut is further tightened. By this, the gasket is bulged and deformed laterally and pressed against the inner peripheral surface of the bag insertion hole, and the gasket is double-sealed to improve the water blocking effect,
Since the inner peripheral portion of the bag insertion hole is closed by the gasket, the exposed portion of the tubular iron can be shielded to prevent rust.
