Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to a water supply and drainage device for construction. Background Art
[0002] The water supply and drainage pipe is the main water supply and drainage system of a building. Through the drainage pipe, residents can discharge domestic wastewater in a timely manner. However, since domestic wastewater usually contains a large amount of impurities, a filter net will be added inside the water supply and drainage pipe to ensure that domestic wastewater can be discharged in a timely manner.
[0003] As the water supply and drainage pipes are used for a long time, more impurities will accumulate on the surface of the filter screen, so the filter screen needs to be cleaned regularly. However, during the cleaning process, the drainage of building wastewater needs to be stopped, resulting in reduced drainage efficiency. To this end, a water supply and drainage device for buildings is proposed. Utility Model Content

[0006] A water supply and drainage device for a building comprises an upper three-way water pipe and a lower three-way water pipe, wherein the two upper ends of the lower three-way water pipe are fixedly provided with filter cartridges, and the interiors of the two filter cartridges are fixedly provided with filter screens, the two lower ends of the upper three-way water pipe are fixedly provided with sealing heads, and the sealing heads are plugged into the interiors of the filter cartridges, fixing mechanisms are provided between the two lower ends of the upper three-way water pipe and the two filter cartridges, and switch valves are provided on both side walls of the upper three-way water pipe.
[0007] Preferably, the fixing mechanism includes a fixing bolt and a fixing nut, the pipe wall of the upper three-way water pipe and the cylinder wall of the filter cylinder are fixedly provided with mounting feet, and the upper and lower mounting feet are fixedly connected by the cooperation of the fixing bolt and the fixing nut.
[0008] Preferably, the sealing head adopts an inverted truncated cone structure, the inner wall of the opening of the filter cartridge matches the sealing head, and the sealing head adopts a rubber head.
[0009] Preferably, the upper end of the upper three-way water pipe and the lower end of the lower three-way water pipe are both fixedly provided with pipe joints.
[0010] Preferably, the interior of the filter cartridge and located above the filter screen is an impurity storage area.
[0011] Preferably, the upper three-way water pipe and the lower three-way water pipe are both UPVC three-way water pipes.
[0012] Compared with the prior art, the present invention provides a water supply and drainage device for buildings, which has the following beneficial effects:
[0013] 1. The water supply and drainage device for a building is provided with filter cartridges and filter screens on both sides of the upper tee water pipe and the lower tee water pipe. The filter cartridges and filter screens on both sides can be opened and closed by corresponding switch valves, so that the two filter screens can be switched for use. When one of the filter screens needs to be cleaned, the pipeline of the corresponding filter screen can be closed, and the pipeline corresponding to the other filter screen can be connected, thereby ensuring that the construction wastewater is continuously discharged while the impurities in the filter screen are cleaned, thereby improving the efficiency of discharging the construction wastewater.
[0014] 2. The water supply and drainage device for a building is provided with fixing bolts and fixing nuts. When cleaning the filter screen, the fixing bolts and fixing nuts are loosened with a wrench, and then the upper three-way water pipe and the lower three-way water pipe are pulled relative to each other to remove the sealing head from the inside of the filter cartridge, thereby exposing the filter screen inside the filter cartridge, making it easier to clean impurities on the surface of the filter screen.
[0015] The parts not involved in this device are the same as the existing technology or can be implemented by using the existing technology. The utility model adopts two water supply and drainage pipes, and each water supply and drainage pipe is provided with a filter screen inside, so that the two filter screens can be switched for use, so that construction wastewater can be continuously discharged while the impurities in the filter screen can be cleaned, thereby improving the efficiency of discharging construction wastewater.
