Device for Preventing the Noise of a Drain Pipe Connected an Elbow Pipe

摘要

The present invention relates to a noise prevention device of the drain pipe connected to the elbow pipe so that the noise is not generated in the process of drainage sewage, so that the noise is not generated during the drainage of the sewage in the elbow pipe connected to the drain trap of the toilet seat.;To this end, a flange 9a is formed on the elbow pipe 5 and on which the lower portion of the first noise absorbing pipe 7 is placed, and the lower portion is located on the discharge side of the elbow pipe and is formed on the drain trap 2. A support ring (10) for supporting a second noise absorbing tube (9) made of rubber material forming a resonance chamber (8a) passed through the resonance chamber (8), and a second noise absorbing tube located at the discharge side of the elbow tube. In the noise prevention device of the drain pipe is connected to the elbow pipe consisting of), the first noise absorption pipe 7 extends to the upper portion of the drain trap (2) and the flange portion (7a) on the upper surface of the first noise absorption pipe The flange portion is formed on the upper surface of the drain trap 2 so that the resonance chamber 8 is formed between the drain trap 2 and the first noise absorbing tube (7).
