A communication shaft hole 55 is provided which communicates with the water flow passage 11 and the upper side of the piston-like shaft portion 53, which is inside the ring-shaped portion 14.

  According to this, since the pressure water is communicated by the communicating shaft hole 55, the hydraulic pressure between the upper side of the piston shaft 53 and the side of the water passage 11 of the piston shaft 53 becomes equal, as shown in FIG. The water stop operation from the water flow state to the water stop state shown in FIGS. 1 and 2 has a particularly advantageous effect of being able to be performed with more uniform and smaller operation resistance. That is, since the resistance applied to the operation does not increase until the water blocking valve body 31 completely closes the communication port 12, the operation can be smoothly performed with a light force.

  Next, an embodiment of the antifreeze water decanter according to the present invention will be described in detail based on the attached drawings (FIGS. 4 to 6). The antifreeze water decanter is an upper and lower displacement of the water draining valve body 41 on the upper side of the water flow on-off valve unit 30 which opens and closes the water passage 11 by the vertical displacement of the water blocking valve body 31 inside the main body 10. The water draining on-off valve unit 40 for opening and closing the water draining passage 20 is disposed, and the water flow on-off valve unit 30 and the water draining on-off valve unit 40 are linked and operated by the vertical movement operation mechanism 70. It is a faucet that can be drained to switch.

Switching from the water flow state shown in FIG. 6 (water shut-off state for the water discharge passage 20) to the water drained state (water shut-off state for the water passage 11) shown in FIGS. Can be done properly. Also, conversely, switching from the draining state (water blocking state for water passage 11) to the water passing state (water blocking state for drain passage 20) similarly causes a time lag to cause water leakage. It can be done appropriately so as not to cause it.
