Description

Technical field:

[0001] The utility model relates to the technical field of water conservancy project construction, in particular to an engineering pipeline connection sealing device. Background technology:

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. They are a general term for projects such as flood control, waterlogging removal, irrigation, power generation, water supply, reclamation, soil and water conservation, immigration, water resource protection (including new construction, expansion, reconstruction, reinforcement, and repair) and their supporting and ancillary projects; projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production;

[0003] The known authorized invention (publication number: CN215000004U) discloses a water conservancy project construction pipeline inner wall connection sealing device, which can play a connection positioning role and also play a better sealing connection role on the inner side of the two sections of the construction pipeline by designing the inner sealing tube, the sealing ring and the sealing ring, thereby greatly improving the overall sealing efficiency;

[0004] When the device is in use, although the sealing effect is improved by setting the sealing ring and the sealing ring, this sealing device needs to be fixed with multiple bolts when connected. The connection process is relatively cumbersome, which not only increases the installation time, but also increases the installation cost. In addition, the use of multiple bolts also increases the complexity of the operation, and has high technical requirements for the installation workers. Once the operation is improper, the sealing effect may be reduced. For this reason, an engineering pipeline connection sealing device is proposed. Utility model content:
