Problems solved by technology

[0005] When assembling the filter cartridge to the mounting seat in the filter device, for those previous filter devices that put the sealing member between the mounting seat, it is necessary to prepare a backup part of the sealing member, so there is Problems that raise costs
In addition, because when replacing the filter cartridge, there is a problem that the sealing member installed between the above-mentioned mounting seat and the filter cartridge deviates from the specified position that exerts the sealing effect, it is necessary to confirm that the sealing member is installed between the mounting seat and the filter cartridge. After the specified position between the filter cartridges, the assembly of the filter cartridge is performed, so the replacement of the filter cartridge is troublesome.

Abstract

A filter has the filter drum installed to its holder on fluid channel by pushing it. It has good sealing between filter drum and said holder without sealing member. The filter drum can be exchanged easily. The installation holder on the spacing member is composed of the inclined surfaces. The second filter drum is composed of the internal and external drums made of resin, which have the relative inclined surface in contact with that of said installation holder. Its inclined surface has the continuous convex rib along its circumference for good sealing.

Description

technical field [0001] The present invention relates to a filter device, in particular to an improved structure of a filter device which can ensure good sealing between a filter cartridge and its mounting seat in the filter device without having to provide a separate sealing member . Background technique [0002] Conventionally, when a fluid such as gas is used in various factories, various filter devices are installed and applied on the pipeline through which the fluid flows. For example, starting from factory equipment, a filter device for compressed air is installed on the pipeline supplying compressed air to various air compressors used in the medical field and nuclear power plants, and the moisture contained in the supplied compressed air, Remove oil and solid objects to protect the above-mentioned air compressors, or maintain the working quality of these air compressors, and improve their workability. [0003] Moreover, in the various initial filter devices for this ...
