Abstract
Description
Technical Field
[0001] The utility model relates to the field of water supply and drainage engineering, in particular to a water supply and drainage pipeline. Background Art
[0002] Building water supply and drainage pipe joints are important components that connect various pipe parts in the water supply and drainage engineering system to ensure smooth water flow and prevent leakage.
[0003] If the pipe near the joint is subjected to uneven external forces (such as pressure fluctuations caused by water hammer, soil movement, temperature changes, etc.), the joint may be subjected to tension, compression or twisting stress, causing the pipe at the joint to bend or deform.
[0004] The pipes at the joints are prone to bending or deformation due to stress, which may cause the pipe joints to no longer be flat, easily forming gaps and causing water leakage. Utility Model Content

[0010] The clamp is also lined with a silicone rubber waterproof layer, which is arranged between the two gear rings. The thickness of the silicone rubber waterproof layer is greater than the tooth height of the gear rings.
[0011] The above design uses two ring gears to reduce the bending or deformation of the two butted pipes between the clamp connection and the pipe interface when subjected to external forces, thereby reducing the generation of gaps. The silicone rubber waterproof layer is then used to fill small deformations or gaps, thereby reducing leakage in the drainage pipe joints. The silicone rubber material has good elasticity, high temperature resistance and chemical corrosion resistance, can adapt to small movements and temperature changes in the pipe, and effectively prevent water leakage in the pipe.

[0030] The length of the silicone rubber waterproof layer 3 is 0.7-0.9 times the length of the clamp 1 ; the length of the clamp 1 is greater than 1 times the inner diameter of the clamp 1 and less than 2 times the inner diameter of the clamp 1 .
[0031] The clamp 1 is made of stainless steel metal; the rib 11 is made of cast iron, and the outside of the rib 11 is provided with waterproof paint; the stainless steel clamp 1 ensures the long-term applicability of the clamp 1, and the cast iron rib 11 improves the deformation resistance of the clamp 1, ensuring that the clamp 1 is not easily deformed.
[0032] A rib 11 is provided on the outside of the clamp 1, and the two ends of the rib 11 extend from the two gear rings 2 at both ends of the clamp 1 respectively; at least three ribs 11 are provided; by providing the ribs 11, the axial deformation resistance of the clamp 1 is enhanced, the bending or deformation of the clamp 1 is reduced, thereby reducing the bending or deformation of the two pipes 5 at the joint, thereby reducing water leakage.

[0037] The inner ring of the silicone rubber waterproof layer 3 is provided with a circular groove 32, and the opening of the circular groove 32 is facing the central axis of the silicone rubber waterproof layer 3. There are at least 6 circular grooves 32 arranged along the central axis of the silicone rubber waterproof layer 3, and the at least 6 circular grooves 32 on the silicone rubber waterproof layer 3 are evenly arranged on both sides of the circular protrusion 31; the design of multiple circular grooves 32 makes the silicone rubber waterproof layer 3 more flexible, can adapt to slight changes and temperature changes, and reduces the risk of cracks and water leakage.
