To realize simplification, downsizing, and cost reduction of a water discharge port and to avoid troubles or failures such as dust clogging in an air passage by protecting an air suction port externally.SOLUTION: An antifreeze water tap post includes a spool valve mechanism 4 that can switch to a water supply mode Ms, a water cut-off mode Mc, or a water removal mode Mr by a spool part 4s that moves up and down through an operation mechanism 3 and disposes a thermo-valve 5 in a water passage R inside a water discharge port 2e, where, when at least an external temperature drops to a predetermined temperature or lower, the thermo-valve 5 is switched to an air suction side to allow air suction into the water passage R inside a water vertical pipe 2 closed by the water cut-off mode Mc, and the antifreeze water tap post shifts to the water removal mode Mr. When constituting the antifreeze water tap post, a residue preventing function Fr that discharges residual water Wo remaining in a water discharge passage Ro at least in the water cut-off mode Mc is provided, and an air suction port 5i of the thermo-valve 5 disposed inside the water discharge port 2e is caused to face the inside of the water discharge passage Ro.SELECTED DRAWING: Figure 1
【課題】 吐水口部のシンプル化及び小型化、コストダウンを図るとともに、吸気口を外的に保護して通気通路のゴミ詰まり等のトラブルや故障を回避する。【解決手段】 操作機構部３により昇降変位するスプール部４ｓにより、給水モードＭｓ，止水モードＭｃ，又は水抜モードＭｒに切換可能なスプール弁機構部４を備え、かつ吐水口部２ｅの内部における通水路Ｒにサーモバルブ５を配設し、少なくとも外気温が設定温度以下まで低下したならサーモバルブ５を吸気側に切換え、止水モードＭｃにより密閉された水道立上管２の内部における通水路Ｒへの吸気を許容して水抜モードＭｒに移行する不凍水栓柱を構成するに際して、少なくとも止水モードＭｃでは吐出通水路Ｒｏ内に残留する残留水Ｗｏを外部に排出する残留防止機能Ｆｒを設けるとともに、吐水口部２ｅの内部に配設したサーモバルブ５の吸気口５ｉを吐出通水路Ｒｏの内部に臨ませる。【選択図】 図１
