technical field

The utility model relates to the field of municipal pipeline engineering, more specifically, the utility model relates to a decontamination joint used for municipal water supply pipelines.

Background technique

Although domestic water has been treated by precipitation, disinfection and filtration, when it is supplied to users, after the tap water passes through the water supply pipeline, it will inevitably carry impurities such as rust and residual sediment in the water, which will affect people's health. In the prior art, such as the application number CN202121565365.0, the bottom of the cylinder is connected with an obliquely arranged intermediate pipe, and the intermediate pipe is arranged obliquely downward to facilitate the discharge of impurities downward through the sewage pipe. When the decontamination joint runs for a period After a period of time, there is no need to close the equipment when cleaning impurities, and there is no need to close the front and rear valves, so that the system is cut off and then disassembled to clean impurities. Only need to open the valve to discharge some impurities in time. Although the above-mentioned decontamination joints can be used without stopping the water supply However, due to the horizontal setting of the filter cartridge, there will still be a lot of residual dirt accumulated in the filter cartridge. These residual dirt are difficult to clean, and the filter cartridge needs to be removed and cleaned frequently, and the filter can only be filtered after the water is cut off. If the filter cartridge is removed for cleaning or replacement, if the residual dirt is not cleaned, the filter cartridge will be blocked and the water supply will be affected. Therefore, the utility model provides a decontamination joint for municipal water supply pipelines to solve the above problems.
