Abstract

PROBLEM TO BE SOLVED: To provide a branch faucet, in which torque of a fixed value or more is required when a spindle is retracted to the end and by which a water outflow path cannot be cut-off only by lightly turning the spindle and retracting the spindle. SOLUTION: The branch faucet consists of a branch faucet member 1 with a branch path 3 and a partition wall 12 for the branch path and a spindle 5 with a cutoff valve 6 being penetrated to the branch faucet member 1 and cutting-off a partition wall 10 for cutoff screwed to a straight stop cock body 2 and a cutoff valve 7 for the branch path cutting off the partition wall 12 for the branch path. A distance between the cutoff valve 6 installed to the spindle 5 and the cutoff valve 7 for the branch path is made shorter than that between the partition wall 10 for cutoff and the partition wall 12 for the branch path, and an elastically deformed projection 14 is formed to a surface butted against the partition wall 12 for the branch path in the cutoff valve 7 for the branch path or a surface butted against the cutoff valve 7 for the branch path in the partition wall 12 for the branch path at that time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branch faucet which is mounted on a water stopcock body to form a branch.

[0002]

2. Description of the Related Art As shown in FIG.
The water stop main body 2 having two water outflow passages 8a and 8b on the downstream side of the water stop partition 10 has an axis in the same direction as the flow axis of water passing through the water stop partition 10. It is installed on the side of the water outflow channel 8a. The branch faucet is composed of a branch faucet member 1 and a spindle 5 having a water stop valve 6 and a branch path water stop valve 7.
The stop cock main body 2 is screwed so as to be movable in the left-right direction in FIG.

[0003] The movement of the branch faucet will be described. First, when the spindle 5 is rotated to move forward (moving to the right) and the water stop valve 6 is brought into contact with the water stop partition 10, Is stopped, and both the water outflow passages 8a and 8b can be brought into a state where no water flows. Next, when the spindle 5 is moved backward (moves to the left) and the water stop valve 6 is disengaged from the water stop partition 10, water flows in from the water inlet 11 as shown in FIG. Flows into the outlet 8b, and the other from the water outlet 8a through the branch inlet 4
It flows into the fork 3. Finally, when the spindle 5 is further retracted, as shown in FIG. 9, the water stop valve 7 for a branch path contacts the branch path inlet 4, and the water flowing from the water inlet 11 flows only into the water outlet path 8 b. Become like

[0004] That is, the branch faucet shown in FIGS. 7 to 9 is configured such that the spindle 5 is gradually retracted from the state in which the water stop valve 6 is in contact with the water stop partition 10, thereby (1) the water outflow path. 8
a and 8b are both still water (see FIG. 7), (2) water outflow channel 8a,
8b both pass water (see FIG. 8), (3) water outflow channel 8a,
