VALVE, FAUCET AND ANTIFREEZE WATER DRAINING PLUG
To provide a valve, a faucet and an antifreeze water draining plug allowing closing operation with further uniform and little operation resistance.SOLUTION: A valve has a top shaft 50 provided with a tip shaft part 51 fixedly disposed with a water cutoff valve element 31, a piston-like shaft part 53 provided at an upper side of the tip shaft part 51, and a rear end connection part 54 provided at an upper side of the piston-like shaft part 53 and connected to a vertical motion operation mechanism 70. The piston-like shaft part 53 of the top shaft 50 is vertically movably sealed and arranged inside a sleeve-like part 14 installed upward from a position forming a water flow passage 11 of a body 10 provided with a communication port 12 and a valve seat 13 of a water flow on-off valve 30. A communication shaft hole 55 communicating the upper side of the piston-like shaft part 53 with the water flow passage 11 is installed to the top shaft 50 inside the sleeve-like part 14.SELECTED DRAWING: Figure 1
【課題】より均一且つより小さな操作抵抗で閉塞操作ができるバルブ、水栓及び不凍水抜栓を提供する。【解決手段】止水用弁体３１が固定状態に配される先端軸部５１と、該先端軸部５１の上側に設けられたピストン状軸部５３と、該ピストン状軸部５３の上側に設けられて上下動操作機構７０に連結される後端連結部５４とが設けられたコマ軸５０を備え、該コマ軸５０のピストン状軸部５３が、通水開閉弁部３０の連通口１２及び弁座１３が設けられている本体１０の通水路１１を形成する部位よりも上側に設けられたスリーブ状部１４の内部に、上下に変位可能にシールされて配され、コマ軸５０には、スリーブ状部１４の内部であってピストン状軸部５３の上側と、通水路１１とを連通する連通軸孔５５が設けられている。【選択図】図１
