Silencer plug-in device for building drainage pipe

Abstract

The invention discloses a building drain pipe silencing insertion device. The device comprises a silencing box, wherein a cleaning port is formed in the bottom of the silencing box, and a down pipe and a guide pipe are spirally connected on the top surface and the right side wall of the silencing box respectively. A sand pit and a buffer ring plate are respectively fixed on the inside top surfaceof the silencing box through buffer springs, and a buffer elastic net is fixed on the inner ring wall of the buffer ring plate. Splash boards are fixed vertically on two sides of the top surface of the buffer elastic net, guide plates are fixed on two sides of the inner bottom surface of the sand pit in a titling mode, fine sand of certain thickness is laid on the inner bottom of the sand pit, a sand-proof net is disposed right above the fine sand, both sides of the sand-proof net are fixed on the inner side walls of the guide plates, and a plurality of overflow ports are formed in the left side wall and the right side wall of the sand pit. By means of the buffer elastic net, the impact force of high-speed water flow is reduced, and noise generated by water flow impact is reduced due to the arranged sand pit.

Description

technical field [0001] The invention relates to the field of connection of building pipes, in particular to a sound-muffling plug-in device for building drainage pipes. Background technique [0002] Building drainage pipes are mainly responsible for the discharge of rainwater and sewage. Generally, the drainage pipes are installed at the corners of the house. When a large amount of water is discharged, there will often be a sound of running water in the water pipes. This is the case at night. It is more obvious. This is mainly due to the impact sound generated by the main water pipe hitting the horizontally arranged diversion pipe from the vertical state when the running water is left from each floor to the next floor. The experience is more obvious. The water pours down directly from a high place, forming a high-speed water column. The water column impacts the diversion pipe at the bottom, forming a huge sound of water flow. This kind of water pipe noise has a very headache...

Problems solved by technology

[0003] At present, the common solutions in the market are generally to set up sound-proof cotton at the joints of water pipes to reduce the intensity of water impact noise spreading outwards. The roof drainage pipe, the sound insulation cotton set on the outer layer is easy to fall off in the wind and the sun, which cannot solve this noise problem for a long time and fundamentally, and the impact of this water flow not only produces noise, but also affects the main pipe and the diversion pipe. The connection of the water pipe will cause lasting impact, which will easily cause water leakage or bursting at the water pipe connection for a long time. Therefore, to solve this problem, we need a sound-absorbing device that can effectively reduce the damage and noise caused by the water flow impact of the water pipe.
