To provide a water supply piping antifreezing mechanism which has a compact configuration, curbs a cost and enables a valve opening temperature to be easily adjusted.SOLUTION: A faucet valve unit 3 comprises, as an antifreezing mechanism: a hollow chamber 44 which is installed in a lower section of a spindle 4 and has an auxiliary valve seat 46 on an upper face of a bottom wall; a movable body 11 which is stored in the hollow chamber so as to be movable in a vertical direction; an auxiliary valve body 14 which is installed at a lower edge of the movable body; a first spring 15 which upwardly energizes the movable body; and a second spring 16 which downwardly energizes the movable body and is made of shape memory alloy. The movable body has: a spring guide provided with a first spring receiving section at an upper edge section of an outer periphery and an energizing convex section at a lower edge section of an inner periphery; and an auxiliary valve body holder 13 which has an engaged section and is almost axial in shape with the auxiliary valve body installed at the lower edge thereof. The first spring is interposed between the spring receiving section and the bottom wall of the hollow chamber. The second spring is interposed between the upper edge section of the auxiliary valve body holder 13 and a top wall of the hollow chamber.SELECTED DRAWING: Figure 2
【課題】コンパクトな構成であって、コストが抑えられ、開弁温度の調整を容易に行うことができる給水配管の凍結防止機構を提供する。【解決手段】水栓弁体ユニット３は、凍結防止機構として、スピンドル4の下部内に設けられかつ底壁上面に副弁座４６を有する中空室４４、中空室に上下移動自在に収容された移動体１１、移動体の下端に設けられた副弁体１４、移動体を上向きに付勢する第１スプリング１５、および移動体を下向きに付勢する形状記憶合金製の第２スプリング１６を備えている。移動体は、外周面の上端部に第１スプリング受け部を有し内周面の下端部にスプリングガイドと、被係止部を有し下端部に副弁体が取り付けられた略軸状の副弁体ホルダ１３とよりなる。第１スプリングは、スプリング受け部と中空室の底壁との間に介在されている。第２スプリングは、副弁体ホルダ１３の上端部と中空室の頂壁との間に介在されている。【選択図】図２
