Abstract

PURPOSE: To efficiently absorb and reduce surge pressure by forming a hole in pipe wall, placing a rubber tube over the outer circumference of the hole and further arranging a protective room in the outer circumference of the rubber tube. CONSTITUTION: A hole 2 is formed in pipe wall of the pipeline 1, a rubber tube 3 is placed over the hole 2 to form an elastic deformation room 4, and a pipe 5 having a big diameter is further placed on the outer circumference of the rubber tube 3 to form a protective room 6. This structure is not only suitable to a new pipeline but also easily suitable to an existing pipeline, high reliability and durability are ensured and the surge pressure can efficiently be absorbed.
