Building water supply and drainage device with self-dredging function

Abstract

The invention belongs to the technical field of water supply and drainage devices, and discloses a building water supply and drainage device with a self-dredging function, which comprises a pipeline, a clamping sleeve is arranged on the side wall of the pipeline, an air inlet pipe is arranged on the side wall of the clamping sleeve in a penetrating manner, and one end of the air inlet pipe is fixedly connected with a connecting pipe; the end, away from the air inlet pipe, of the connecting pipe is fixedly connected with an air nozzle. A dredging ring is arranged in the pipeline, the bottom face of the dredging ring is fixedly connected with a pressure-bearing cylinder, and the pressure-bearing cylinder is matched with the air tap. According to the pipeline dredging device, high-pressure air is sprayed out through the air nozzle to impact the pressure-bearing cylinder, the pressure-bearing cylinder drives the dredging ring to ascend, then sundries in a pipeline and dirt attached to the inner wall of the pipeline are removed, and therefore automatic pipeline dredging is achieved.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage devices, in particular to a building water supply and drainage device with a self-dragging function. Background technique [0002] With the acceleration of urbanization and the improvement of building energy-saving requirements and the continuous development of the construction industry, the building water supply and drainage system is one of the essential building facilities, and the scale and some pollution in the water of the building water supply and drainage pipes in use The pollutants are easily adsorbed in the drainage pipes, and as time goes by, they will accumulate more and more, which will easily cause the drainage pipes to be blocked. Once the blockage occurs, it will affect the smooth discharge of sewage, and even backwater or water leakage will occur. However, the existing building water supply and drainage devices do not have the function of self-dredging. If there ...

[0002] With the acceleration of urbanization and the improvement of building energy-saving requirements and the continuous development of the construction industry, the building water supply and drainage system is one of the essential building facilities, and the scale and some pollution in the water of the building water supply and drainage pipes in use The pollutants are easily adsorbed in the drainage pipes, and accumulate more and more as time goes by, which is easy to cause the drainage pipes to be blocked. Once the blockage occurs, it will affect the smooth discharge of sewage, and even reverse water or water leakage will occur

However, the existing building water supply and drainage devices do not have the function of self-dredging. If there is a blockage during use, it is necessary to contact professionals to clear it, which is time-consuming and affects the quality of people's daily life. Therefore, we propose a self-dredging function The building water supply and drainage device is used to solve the above problems
