Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, specifically a water supply and drainage pipe connection device. Background Technology

[0002] Municipal water supply and drainage refers to the urban water supply system, drainage system, and building water supply and drainage, often simply called water supply and drainage. Water supply engineering provides domestic water for residents, factories, mines, and transportation enterprises, as well as fire-fighting water, road and greening water, etc. It consists of water source, water intake structure, raw water pipeline, water treatment plant, and water supply network, and has the function of collecting and transporting raw water and improving water quality. Drainage engineering is the project to remove domestic sewage, various wastewaters from production, and excess surface water.

[0003] Chinese patent application number 202310060304.6 discloses a water supply and drainage pipe connection device, including a first pipe and a second pipe to be connected. A first connecting ring is fixed at the pipe opening of the first pipe, and a second connecting ring is fixed at the pipe opening of the second pipe. A fixing block is fixed on the side of the second connecting ring away from the second pipe. A fixing groove adapted to the fixing block is formed on the first connecting ring, and a locking element corresponding to the positioning groove is provided on the first connecting ring. The device achieves the function of initially limiting the distance between the first and second connecting rings by setting a limiting groove, a limiting block, and a spring. It achieves the function of limiting and fixing the distance between the first and second connecting rings by setting a connecting block, a limiting slide rod, and a slot. It prevents liquid leakage by setting a sealing ring, a sealing ring, and an external thread. The water supply and drainage pipe connection device provided by this invention is easy to assemble and disassemble, simple to operate, easy to use, and has strong connection stability.

[0004] The current water supply and drainage pipe connection device only seals the connection by using a sealing ring between the first and second connecting rings. After prolonged use, corrosion of the sealing ring can cause gaps to appear at the connection, leading to water leakage and reducing its practicality. Therefore, we propose a new water supply and drainage pipe connection device. Utility Model Content
