A device for fixing the position of a tube in an annular cross-sectional flow path formed by inserting a tube with both ends blocked in a pipe.
A device for fixing the position of a tube in an annular cross-sectional flow path formed by inserting a tube with both ends blocked in a pipe.
The present invention relates to a support device for self-supporting a tube and maintaining the center of the tube in the center of the pipe in an annular cross-sectional flow path formed by inserting a tube blocked at both ends into the pipe, and more specifically, inside the header and the pipe. The tube made of silicone rubber is installed at the center of the header and inside of the pipe to prevent breakage due to freezing even in the cold weather in winter so that the internal pressure increase due to the volume expansion even if the water inside the pipe and the header is frozen The present invention relates to a position fixing device of a silicone rubber tube which can prevent the breakage of the pipe and the header by temporarily contracting and absorbing the rubber tube.;In inserting the silicone rubber tube 16 into the pipe 14 and the header 12, Insert the ring of shape at regular intervals The ring is repeatedly installed at regular intervals such that the protruding portion of the ring faces the 12, 3, 6 and 9 o'clock directions or uses a spring 10 having two inner diameters. The spring 10 adheres to the silicone rubber tube 16, and the spring 10 having a large inner diameter adheres to the inner wall of the header 12 and the pipe 14 to support the silicone rubber tube 16 in any case. Located in the center of the pipe 14 and the header 12, so that the water flowing inside the header 12 and the pipe 14 can flow smoothly through the space between the fixing device and the silicone rubber tube (16). It is the position fixing device of the tube in the flow path of the annular cross section comprised.
