Description

Technical Field

[0001] The utility model relates to the technical field of heating filters, in particular to a magnetic flange valve cover sewage filter. Background Art

[0002] Before the heating season arrives, the staff of the heat exchange station prepares for the heating season. They need to clean all the filters in the community units. The removal of the flange valve cover filter is relatively complicated and the workload is large. Cleaning the filter usually requires two people to work together. The operation process is: first close the valves before and after the filter, remove some bolts on the valve cover to release the pressure, and after the pressure is reduced, remove the valve cover to take out the filter for cleaning. After cleaning, put the filter back, install the valve cover, and finally open the valves before and after the filter. Under ideal circumstances (meaning that there is enough operating space and the front and rear valves can be closed tightly), it takes 10-15 minutes for two people to clean a unit filter. The workload is huge. The thermal staff is short of staff and needs to recruit seasonal workers to work with the thermal staff to prepare for heating. Utility Model Content

[0020] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] like Figure 1As shown, this embodiment provides a magnetic flange valve cover sewage filter, including a valve body 1, a water inlet 2 on one side of the valve body 1, and a water outlet 3 on the other side. The valve body 1 is connected to a filter pipe 4, and a filter 5 is provided in the filter pipe 4 to intercept impurities. The end of the filter pipe 4 is connected to a flange valve cover 6, and a slag storage tank 8 is provided in the flange valve cover 6. A magnet 9 is also provided on the flange valve cover 6. Because of the flow requirement problem, the filter 5 cannot be made too precise to increase resistance and reduce flow, which will cause fine particles to enter the user's home. After the small particles are deposited, they will block the pipeline, resulting in insufficient flow rate and the heating will not be hot. The blockage of the unit filter will cause the entire unit community to be underflow, resulting in a large number of complaints. At this time, the staff needs to clean the unit filter, and it takes a long time to clean the unit filter. When using this filter, hot water from the thermal power station enters the filter pipe 4 through the water inlet 2, impurities are intercepted by the filter 5, and the filtered water flows from the filter pipe 4 to the water outlet 3 to complete the filtration. In addition, when the water passes through the filter pipe 4, it flows through the slag tank 8, and fine rust is adsorbed by the magnet 9 in the slag tank 8. The flange valve cover 6 is also provided with a ball valve 7. During the continuous interception and filtration, the filter 5 will slowly become clogged, and there will be more and more impurities in the slag tank 8. At this time, the ball valve 7 needs to be opened, and the water flows from the water inlet 2 into the filter pipe 4 and is directly discharged by the ball valve 7. The blocked filter 5 and the slag tank 8 are rinsed clean by water pressure. After cleaning, the ball valve 7 is closed, and the water flow resumes entering the filter pipe 4 from the water inlet 2, and the impurities are intercepted by the filter 5. The filtered water flows from the filter pipe 4 to the water outlet 3 to continue filtering.

[0023] In this embodiment, the flange valve cover 6 and the filter screen tube 4 are fixed by bolts and nuts, and a steel gasket 12 is provided at the connection between the flange valve cover 6 and the filter screen tube 4 to increase the sealing performance and prevent water leakage.

[0024] Since thermal water is high-temperature water, it will affect the life of the magnet, and in order to ensure the flow of the thermal pipeline, in this embodiment, the magnet 9 is arranged on the outside of the flange valve cover 6 to avoid contact with water. Specifically, a magnet bin 10 is provided on the periphery of the flange valve cover 6, and the magnet 9 is placed in the magnet bin 10. After the magnet 9 is placed in the magnet bin 10, it is sealed with a cover 11. In this embodiment, the cover 11 is detachably connected to the magnet bin 10, which is convenient for the replacement of the magnet 9 at a later time. Specifically, the cover 11 is threadedly connected to the magnet bin 10, and the cover 11 can be screwed on the magnet bin 10. The outside of the cover 11 is a hexagonal protrusion for easy disassembly.

[0025] The magnetic flange valve cover sewage filter is based on the Y-type filter design. The HVAC filter is different from other industries. When the pressure is sufficient, it is also necessary to minimize the resistance to maintain the user's home flow. The ordinary filter structure consists of three parts: the filter body, the filter screen 5 and the flange valve cover 6. The main impurities in the thermal water circulation process are radiators or pipes. Because oxidation produces more and more rust, the filter flange valve cover 6 is connected to the filter screen pipe 4 by bolts. To prevent water leakage, a steel pad 12 is sandwiched between the flange valve cover 6 and the filter screen pipe 4; the slag storage tank 8 can store more rust impurities. The outer end of the tank body has a cavity for placing a strong magnet 9, and is sealed with a cover 11, so that the magnet 9 is in a closed space to maintain the stability of the magnet 9, so that the magnet 9 has a longer service life. In the application of thermal pipelines, the temperature and flow of water are the primary factors. Water needs to resist many resistances such as elbow resistance and pipeline friction resistance during the flow process. In order to maintain the flow, obstacles must be reduced in the pipeline, and thermal water is high-temperature water, which affects the life of the magnet 9, so it is chosen to place the magnet 9 outside the filter. The filter of this embodiment can increase the ability of the filter to filter impurities without reducing the user's water flow. The fine particles accumulate at the flange valve cover 6, which can reduce the entry of impurities into the user's home, extend the maintenance period of the user's home heating facilities, and reduce the workload of thermal workers.

[0026] Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in this application.
