    • A valve for preventing freeze-fracturing prevents accidental freeze-fracturing due to the freezing of water by draining water from a flow pipe before the danger of freezing occurs when the temperature of ambient air drops. The valve for preventing freeze-fracturing includes a housing coupled to a pipe port and a draining chamber provided in a portion of the housing that faces the pipe port. The draining chamber has therein a water inlet hole, which communicates with an inside of the flow pipe, and a water outlet hole, which communicates with an outside of the housing. A storage chamber is provided in a portion of the housing that is opposite the draining chamber, and contains therein a phase change material, which decreases in volume while changing in phase from liquid to solid. A plunger is movably disposed in the draining chamber to open and close the water inlet hole.
    • 用于防止冻结压裂的阀防止在环境空气的温度下降之前发生冷冻危险之前通过从流动管排出水而导致由于水冻结造成的意外冻结压裂。 用于防止冻结压裂的阀包括联接到管口的壳体和设置在壳体的面向管口的部分中的排水室。 排水室具有与流管的内部连通的进水孔和与壳体的外部连通的出水孔。 储存室设置在壳体的与排水室相对的部分中,并且包含相变材料,相变材料在从液体到固体的同相改变时体积减小。 柱塞可移动地布置在排水室中以打开和关闭进水孔。
