Description

Technical Field

[0001] The utility model relates to the technical field of gas filters, in particular to a gas filter provided with a sealing structure. Background Art

[0002] A gas filter is a device used to filter impurities in gas. It is usually composed of a filter element, a shell, an inlet and an outlet, etc. Gas filters are widely used in industries such as industry, energy, and environmental protection, where high gas cleanliness is required.

[0003] Common gas filters and connecting covers are usually positioned with bolts, which have poor sealing effects and are prone to gas leakage after long-term use. The bolts may loosen during long-term use, resulting in failure of positioning between the gas filter and the cover, which has certain adverse effects on people's use process. For this reason, we propose a gas filter with a sealing structure. Utility Model Content

[0004] Technical problems solved: In view of the shortcomings of the prior art, the utility model provides a gas filter with a sealing structure, which has the advantages of sealing and easy disassembly and assembly. The gas filter body and the upper positioning connection cover can be sealed and connected through the provided sealing connection mechanism. A No. 1 sealing rubber edging and an insert positioning ring block are inserted into the interior of the gas filter body. At the same time, the inner limit sealing block and the No. 2 sealing rubber edging are inserted into the inner limit sealing groove for positioning, thereby achieving a double sealing effect. The positioning through block is then inserted into the positioning through hole. The damper and the elastic member have a certain tension, so that the anti-detachment control block can be pushed outward, thereby firmly positioning the upper positioning connection cover and the gas filter body to prevent detachment. The lower end of the anti-detachment control block contacts the upper end of the sealing rubber pad, and the sealing rubber pad is used to support the anti-detachment control block, thereby preventing the anti-detachment control block from loosening, and also preventing the upper positioning connection cover and the gas filter body from loosening, thereby improving the sealing effect.
