AI Technical Summary

Technical Problem

The existing building's silencer pipes for water supply and drainage are easily affected by water and cause noise when draining, and are easily damaged after long-term use.

Method used

A building that includes internal tubes, external tube and telescopic components is designed to pass the wall tube for drainage and discharge. The external pipe is connected to the wall, the internal tube is set inside the external tube, and the four telescopic components are evenly set up between the inner tube and the outer pipe. Each telescopic component includes the telescopic rod, spring and fixed block. , The telescopic rod and spring shrink or stretch when the water flow is impacted, reducing the impact of the water flow on the inner tube.

Benefits of technology

It effectively reduces the impact of water flow on the inner pipe, thereby reducing noise and extending the service life of the silencer wall pipe.

Abstract

The utility model relates to the technical field of building water supply and drainage, in particular to a building water supply and drainage silencing through-wall pipe which comprises a wall body, an inner pipe, an outer pipe and four telescopic assemblies, the outer pipe is connected with the wall body in a sliding mode and located in the wall body, the inner pipe is arranged in the outer pipe, and the four telescopic assemblies are evenly arranged between the inner pipe and the outer pipe. Each telescopic assembly comprises a plurality of telescopic rods, a plurality of springs and a fixing block, one ends of the telescopic rods are fixedly connected with the outer pipe, the other ends of the telescopic rods are fixedly connected with the fixing block and located between the outer pipe and the inner pipe, one side of the fixing block is arranged in an arc shape, the fixing block is matched with the inner pipe, and the surfaces of the telescopic rods are wrapped with the springs. By means of the arrangement of the structure, the noise reduction through-wall pipe solves the problems that in the prior art, when water is drained, the noise reduction through-wall pipe body can be directly impacted by water, the generated noise is large, and the noise reduction through-wall pipe body is prone to being damaged after being used for a long time.
