摘要： The present invention provides a pipe connecting structure including a male flange block combined with a first pipe and a female flange block combined with a second pipe, which is fastened to the male flange block by fastening means, where a protrusion having a hole that communicates with the first pipe is formed through the male flange block, and an insert portion into which the protrusion is inserted is formed through the female flange block, and a sealing member to closely contact with the end face of the protrusion is seated on the bottom inside the insert portion, and the sealing member includes an inner sealing part of soft metal and an outer sealing part of rubber tightly fitted around the outer circumference of the inner sealing part. Therefore joints between pipes, a heat exchanger and a pipe, or two components can bear high pressures in a refrigerating cycle system using a CO2 refrigerant, air tightness can be maintained under low and high temperatures without changes in quality and shape of a sealing members, and it is possible to prevent and minimize leakage of the refrigerant by preventing permeation of CO2.

摘要翻译：一种管连接结构，包括与第一管组合的阳凸缘块和与第二管组合的阴法兰块，其通过紧固件固定到阳凸缘块，其中具有与第一管连通的孔的突起是通过阳凸缘块形成，并且通过阴凸缘块形成插入突起的插入部分，并且与突起的端面紧密接触的密封构件位于插入部分的底部，并且密封构件包括软质金属的内密封部分和密封地装配在内密封部分的外圆周上的橡胶的外密封部分。因此，在使用二氧化碳制冷剂的制冷循环系统中，管道，热交换器和管道或两个部件之间的接头可承受高压，在低温和高温下可以保持气密性，而不会改变密封构件的质量和形状，并且可以通过防止CO 2的渗透来防止和最小化制冷剂的泄漏。
