PROBLEM TO BE SOLVED: To inhibit foreign objects from accumulating between a valve body and a valve seat to unfailingly stop water when the valve body contacts with the valve seat.SOLUTION: A fire hydrant 1 includes: an inflow part 10 which is connected with a water pipe for flowing water and into which the water flowing in the water pipe flows; and a valve seat 25 which is connected with the inflow part 10 so as to face the water pipe through the inflow part 10. The inflow part 10 has an inner wall 10c through which the water flowing into the inflow part 10 passes. The inner wall 10c has a spiral groove 10f formed into a spiral form along the inner wall 10c.SELECTED DRAWING: Figure 2
【課題】弁体及び弁座の間に異物が堆積することを抑制して弁体が弁座に当接したときに確実に止水する。【解決手段】消火栓１は、水が流れる水道管に接続され且つ水道管を流れる水が流入する流入部１０と、流入部１０を介して水道管に対向するように流入部１０に接続される弁座２５とを備え、流入部１０は流入部１０に流入した水が通過する内壁１０ｃを有し、内壁１０ｃは内壁１０ｃに沿って螺旋状に形成される螺旋溝１０ｆを有する。【選択図】図２
