FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic diagram of an embodiment of the present utility model;
fig. 3 is a schematic structural diagram of a second embodiment of the present utility model.
Detailed Description
As shown in fig. 1, a sealing air filter element comprises a filter element body 100, the filter element body 100 is provided with a filtering part 110 and a mounting part 120, the mounting part 120 is provided with an external thread 130 for assembling with a filter or a pipeline, the mounting part 120 is also provided with a sealing structure for sealing effect when assembling with the filter or the pipeline, the sealing effect of the joint of the filter element and the filter or the pipeline can be ensured by matching the sealing effect of the sealing structure with the filter element in a threaded assembling mode, and unfiltered air is prevented from passing through an assembling gap of the filter element, so that normal use of equipment is affected or the air filtering effect is affected.
The filter element body 100 is lined with a stainless steel hollow rod (not shown in the drawings), and the stainless steel hollow rod is added to improve the overall strength of the filter element body 100, and the stainless steel hollow rod is required to be used as a lining structure for supporting the filter element body 100 because the filter element may work under high temperature conditions, such as filtering steam, and under the condition of too high temperature, the filter element is softened.
Embodiment one; as shown in fig. 2, the sealing structure is a sealing ring 200, the outer wall of the mounting portion 120 has a limiting groove 121 for positioning the sealing ring 200, and the sealing ring 200 is disposed in the limiting groove 121.
At least one sealing ring 200 is arranged; in this embodiment, the sealing structure adopts the sealing ring 200, and the matching tightness and the sealing effect between the sealing ring 200 and the filter element body 100 are improved by arranging the limiting groove 121 on the outer wall of the mounting part 120.
Embodiment two; as shown in fig. 3, the difference between the present embodiment and the first embodiment is that the sealing structure is a sealing gasket 300, an annular sealing protrusion 310 is provided on one end surface of the sealing gasket 300, which is attached to the filter element body 100, and correspondingly, an annular sealing groove 122 is provided on the filter element body 100, when the sealing gasket 300 is assembled with the filter element body 100, the annular sealing protrusion 310 of the sealing gasket 300 is embedded into the annular sealing groove 122 of the filter element body 100, and the annular sealing protrusion 310 and the annular sealing groove 122 are provided to improve the matching tightness and sealing effect of the sealing gasket 300 and the filter element body 100.
The utility model has the beneficial effects that: the utility model provides a sealing air filter, which is characterized in that an external thread is arranged at the installation part of a filter element and matched with a sealing ring or a sealing gasket to realize sealing assembly, so that the filtering effect is improved, unfiltered air is prevented from flowing in from a gap between the filter element and a pipeline or a filter assembly part, and the sealing air filter is simple in structure, low in manufacturing cost and very practical.
The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be appreciated by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the utility model, and that simple modifications and substitutions by those skilled in the art are within the scope of the utility model without departing from the spirit and scope of the utility model.
