According to an embodiment of the present invention, a gas-liquid circulating type gas hydrate reactor, includes: a reactor body configured to be supplied with gas and water to generate a gas hydrate; and a bubble generator configured to be disposed around a lower portion of the reactor body, wherein the gas supplied from the lower portion of the reactor body is jetted into the reactor body through the bubble generator. The gas-liquid circulating type gas hydrate reactor in accordance with the present invention makes it possible to jet gas at a high speed by using the bubble generator disposed at the low portion of the reactor body so as to promote the reaction of water and gas which are accommodated in the reactor body while forming a water stream at the lower portion of the reactor body that enables a smooth agitation of the water and the gas.

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.
