Description

M356039 VIII. New description: [New technical field] New inner and outer diameter plastic parts 'is used for drainage system and sewage system parts' such as elbows, joints, water three-way, Yangming ladder, inclined ladder, different diameter Parts such as tees can be quickly joined to the pipeline. [Prior Art] • Plastic parts for general drainage systems and sewage systems, such as elbows, two-way, etc. When the double flared parts are joined to the pipeline, there will be a side-to-counter joint, and the reverse water joint will easily cause water leakage. When the single flared part is engaged with the pipeline, it must rely on the gas burner to make the shrinkage action, resulting in labor and consumables. When joining with the cement wall pipe, the whistle must be driven out of the wall of the pipe, and it is easy to break the original pipe, and after processing, it can be combined with: • The joint is made, which makes the construction difficulty increase. More time consuming. [New content] It is contrary to the shortcomings of the previous parts: 1. Construction takes time. 2. Gas supplies. 3. Reverse water joints. It can quickly reach the new inner and outer diameter plastic parts of the water. It can be used without the blowtorch, that is, 6 M356039. It can improve the shortcomings of its previous parts, making it easier to configure the drainage g or forest pipeline, so that the specialization can be achieved. Attached. [Embodiment] As shown in the figure, the water pipe of the fine water pipe is connected. 1 expansion interface in the outer diameter of the g road, 7 shrinkage, joined to the inner diameter of the pipeline, along the direction of the water flow to complete the pipeline configuration.

M356039 IX. Scope of application: A plastic part with inner and outer diameter is used for the drainage system or the sewage system. The parts have an outlet for shrinkage, so that the parts can be directly inserted into the inner diameter of the pipeline, making the construction more convenient and convenient. .
