[Industrial applications]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saddle water faucet with a joint, and more particularly to a saddle water faucet with a fitting joint and a plug for use in the same.
[0002]
[Prior art]
Conventionally, when a water distribution pipe is connected to a saddle water tap, a separately configured joint has been used. However, recently, a water pipe directly connected to a water tap (for example, Patent Document 1) has been proposed. It has been developed and is widely used.
[0003]
Further, after attaching the saddle water tap to the water supply main pipe, in order to perforate a water distribution hole in the water supply main pipe, a cap at the top of the water tap is removed, and a drilling machine is inserted from above to perform the drilling. 2), but the discharge of chips generated at the time of drilling depends exclusively on the blowing force due to the water supply pressure of the water supply main pipe, and no special consideration is given.

[Problems to be solved by the invention]
However, when a saddle water tap with a fitting, particularly a fitting fitting called a one-touch fitting, is directly configured in the water tap, the opening end of the one-touch fitting mechanism can be formed by drilling a water hole in the water supply main pipe. There is a problem that swarf generated at the time of perforation simply enters the fitting mechanism or the water faucet mechanism simply by closing with the cap.
[0006]
Therefore, if the discharge of the chips generated at the time of drilling was dependent only on the blowing force due to the water supply pressure of the water supply mains, the removal of the chips was insufficient, and in particular, the material of the water supply mains to be drilled was not sufficient. Some of them are mixed into drinking water and reach the end-of-stream equipment, and it has been required to remove chips more completely.
[0007]
In addition, even if the chips are not mixed into the drinking water, if they enter the surroundings of the ball valve, which is the mechanism of the water faucet, the ball seat, or the fitting mechanism, the mechanism may cause biting or poor connection. It may cause water leakage or failure.
[0008]
Further, since the discharge of chips generated during drilling depends on the blowing force of the water supply pressure of the water supply main pipe, the pipe insertion lubricant applied to the L-shaped packing in the pipe joint at the time of chip discharge is subjected to hydraulic pressure. There is a problem that is washed away by.
[0009]
In order to cope with the above inconveniences, when drilling a water distribution hole in a water supply main pipe, a great deal of effort is required to apply a stopper ring 42, a retaining ring 43, an L-shaped packing 44, a joint cap, which constitute a one-touch fitting mechanism. There is a problem that the hole cannot be pierced unless all members such as 45 are removed and the base opening of the plug main body to which the fitting mechanism is attached is closed with the cap.
[0010]
