QUICK FREEZING DEVICE OF WATER PIPE

摘要

PURPOSE: A quick freezing device of a water pipe is provided to replace the pipe after blocking the water flow by freezing the pipe with solid dry ice. CONSTITUTION: A quick freezing device of a water pipe comprises fixed body(10), a fixed body combining member(20), a guide groove(30) and a pressing member(40). The fixed body comprises a central space part(12) surrounded with the circumference of a small-diameter pipe. The fixed body is divided into two parts based on a central space part. Split ends(22) of the combining member are formed in the central space part outside of the fixed body. The split ends are combined with the magnetic force. Solid dry ice is inserted into the guide groove. The guide groove is carried to the central space part. The pressing member pressurizes the dry ice toward the central space part.
