Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a pipeline inner wall connection device for water conservancy projects. Background Technology

[0002] In today's water conservancy engineering field, the connection effect of pipelines directly affects the quality and efficiency of the project. With the continuous advancement of water resource development and utilization, the scale of water conservancy projects is becoming increasingly large, and the requirements for pipeline connections are becoming more and more stringent. Previous pipeline inner wall connection methods have many limitations, such as poor sealing leading to leakage, poor durability, and complex construction. Therefore, in order to meet the development needs of water conservancy projects, it is urgent to develop high-performance pipeline inner wall connection devices to ensure the safe and stable operation of water conservancy systems.

[0003] Existing pipe connection seals directly seal the connection between two pipes using sealant, leaving gaps between the inner walls of the pipes. Furthermore, due to the high pressure inside water pipes when transporting water or gas, the connection between pipes is prone to leakage after long-term use.

[0004] An existing patent (publication number: CN220647102U) proposes a sealing device for the inner wall connection of water conservancy engineering pipelines, relating to the field of water conservancy engineering pipeline technology. It includes a sealing connection device, a first water conservancy pipeline, and a second water conservancy pipeline. The sealing connection device includes a separator ring, and an outer sealing plate is fixedly installed on the outer wall of the separator ring. This invention achieves a sealed connection between the two water conservancy pipelines by inserting the first water conservancy pipeline into the space between the outer sealing plate and the inner wall sealing plate on the left, and inserting the second water conservancy pipeline into the space between the outer sealing plate and the inner wall sealing plate on the right, and by pressing a waterproof sealing gasket. The gap between the outer sealing plate and the outer walls of the first and second water conservancy pipelines is sealed and fixed using sealant, and the gap between the inner wall sealing plate and the inner walls of the first and second water conservancy pipelines is sealed and fixed using waterproof sealant. This completes the sealed connection of the two water conservancy pipelines, eliminating the risk of leakage at the connection point and achieving a tighter connection.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, most existing devices use waterproof sealant and connectors to connect the inner walls of pipes. During prolonged use, the sealant will gradually age due to increased usage time and changes in environmental pressure, thus affecting the sealing effect. Furthermore, in actual use, the two pipes in the connected state may experience vibration or shaking, which will affect the sealing performance and service life of the connectors.

[0006] Therefore, a connection device for the inner wall of water conservancy engineering pipelines is proposed. Utility Model Content
