[0002] Central heating refers to the way of supplying steam and hot water generated by a central heat source to a city (town) or part of the area through a pipe network to meet the heat requirements for production, heating and daily life.

[0003] Central heating is one of the infrastructure of modern cities and an important facility of urban public utilities. The existing hot water conveying devices for central heating have certain limitations in function, especially in terms of filtration effect. The hot water often contains water stains and impurities. Over time, these sediments will gradually accumulate in the pipeline, resulting in pipeline blockage, seriously affecting the flow efficiency of hot water and the heating effect. This not only increases the maintenance cost, but also may cause the shutdown of the heating system, bringing inconvenience to users. In addition, the existing filtration devices on the market also have deficiencies in design. Many devices are not convenient to replace, often requiring a long shutdown time and complex operation procedures. This situation not only wastes a lot of manpower and material resources, but also may lead to the interruption of hot water supply, affecting the daily life of users. Content of the Utility Model
