Device and construction method for preventing pipeline from being damaged due to solidification and expansion of medium

Abstract

The invention discloses a device for preventing pipelines from being damaged due to medium solidification and expansion, and a construction method thereof, which comprises a rubber tube laid on the inner bottom of the transportation pipeline, and the two ends of the rubber tube extend from a connecting flange at the bottom of the transportation pipeline to the transportation pipeline On the outside, the end is integrally provided with a ring-shaped fastening seal ring and is closed by the valve core. A flange plate is installed on the outside of the connecting flange through fastening bolts, and the flange plate and the connecting flange compress the fastening seal ring to seal , the rubber tube is filled with air through the air compressor, and its internal air volume is greater than the volume increase when the medium inside the transportation pipeline solidifies. The present invention installs a rubber tube in the transportation pipeline and fills the rubber tube with an appropriate amount of air to provide sufficient accommodation space for the volume expansion caused by the solidification of the medium in the transportation pipeline, and avoids the pipeline damage caused by the solidification and expansion of the medium in the transportation pipeline of the system. .

Description

Technical field [0001] The present invention relates to the field of pipeline antifreeze techniques, and more particularly to devices that prevent damage caused by dielectric solidification and its construction method. Background technique [0002] In the cold region of the northern, the water supply or other liquid medium pipe is not perfect or although there is an insulation structure but does not have a continuous heat source (such as electric heating), due to the loss of the pipeline damage, the pipe is damaged, in the second When the temperature rises from the year, the loss of other items is damaged due to the loss of other items, which seriously affects the normal operation of the system. Inventive content [0003] SUMMARY OF THE INVENTION It is an object of the present invention to propose a device for preventing damage to a dielectric solidification expansion and its construction method to solve the technical problems described in the background art. [0004] In order t...

AI Technical Summary

Problems solved by technology

[0002] In the northern cold regions, due to the imperfect insulation of water supply or other liquid medium pipelines or the lack of continuous heat source (such as electric heat tracing) for heat supply despite the insulation structure, the pipeline is damaged due to the solidification and expansion of the liquid medium. When the annual temperature rises, the pipeline is damaged and the medium melts and leaks, causing other items to be polluted and damaged, which seriously affects the normal operation of the system.
