Also has a constant flow valve as a preferred embodiment.

[0009]

In the branch faucet of the present invention, the water inflow pipe and the water outflow pipe that communicate with the water passage for the branch water flow from the stop cock body are integrally formed, and the water inflow pipe corresponds to the water flow of the stop cock body. Since it has a water shutoff valve, it is possible to remove the water shutoff valve or the like of the water shutoff plug body and mount it directly there. Further, as the water shutoff valve, one removed from the water shutoff valve main body can be used, and moreover, the spindle for holding this water shutoff valve is located on substantially the same line as the spindle provided in the water shutoff valve main body. Therefore, the water stop operation can be performed from the same direction as that of the water stop cock body.

Further, in the branch faucet of the present invention, the water outflow pipe communicating with the water inflow pipe has a water stop valve, and only the branch water flow can be selectively stopped. Moreover, when the water outflow pipe is erected vertically, the spindle of the water shutoff valve can be operated from above. In that case,
Since the stop valve stops the reverse flow of the branched water flow by its own weight,
No pressing spring or the like is required, and the structure is simplified.

Furthermore, when the outlet of the water outflow pipe is directed downward, the distribution pipe for the branched water flow can be attached vertically to the outlet, and the connecting work becomes easy.
