Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, and specifically relates to a pipe sealing structure for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering. Only by building water conservancy projects can water flow be controlled, floods be prevented, and water volume be regulated and distributed to meet the water needs of people's lives and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, rafts, and fishways to achieve their goals.

[0003] Patent application number 202120421099.8 discloses a pipeline for hydraulic engineering, comprising: a first pipeline, a second pipeline, a first flange, and a second flange; the first flange is fixed to the first pipeline, and the second flange is fixed to the second pipeline, the first flange and the second flange being connected in a mating manner; it also includes a sealing structure for being disposed between the first flange and the second flange; the sealing structure includes: a first semi-circular ring and a second semi-circular ring, a first semi-circular sealing gasket being disposed on the inner wall of the first semi-circular ring, and a second semi-circular sealing gasket being disposed on the inner wall of the second semi-circular ring; the first semi-circular ring and the second semi-circular ring are combined to form a ring, the inner diameter of the ring being larger than the outer diameter of the first flange, and the inner diameter of the ring being larger than the outer diameter of the second flange. The hydraulic engineering pipeline provided by this solution, due to the addition of the sealing structure, can effectively improve the sealing effect of the flange.

[0004] However, for non-metallic pipes, the connection between the flange and the pipe is prone to loosening, which affects the overall use. The existing method of using a sealing gasket to connect the two pipes is prone to aging of the sealing gasket over time, which affects the sealing performance. Utility Model Content

[0005] In view of this, the present invention provides a pipe sealing structure for water conservancy projects. The left connecting mechanism and the right connecting mechanism are respectively connected and fixed to two pipes through two connecting parts. Then, the two connecting parts are sealed and connected to the left connecting mechanism and the right connecting mechanism through the first fixing bolt and nut, thereby improving the stability and sealing performance of the connection between the two pipes.

[0006] The technical solution is as follows: A pipe sealing structure for water conservancy projects includes a left connecting mechanism and a right connecting mechanism connected to a pipe.
