Abstract
The utility model discloses a leak-proof sealing structure of an upper opening cover of a filter. The leak-proof sealing structure comprises an upper opening cover, a filter shell and a seal ring, wherein the seal ring is arranged on the upper opening cover; a flange is also arranged outside the upper edge of the filter shell. The leak-proof sealing structure has the advantages that the flange is additionally arranged on the upper edge of the filter shell so as to increase the sealing contact surface of the seal ring, a good sealing effect can be achieved by closing the upper opening cover on the shell, liquid leakage and vacuum leakage are avoided, the service life of the seal ring is prolonged, and the difficulty for mounting alignment is also reduced.
Description
Technical field
The utility model relates to a kind of container leak-proof sealing structure, particularly a kind of filter upper flap leak-proof sealing structure.
Background technology
Alcohol extracting, the per tour of water extraction filter need to be opened upper flap, and the screen pack that takes out the inside washs.Upper flap and filter housings seal by the sealing ring being arranged in upper flap, and upper flap closing lid is on housing, and sealing ring contacts sealing with housing top edge.This action need when mounted, carries out contraposition to sealing ring and housing top edge, aligns badly, seals not in placely, while filter being moved to liquid with vavuum pump, often occurs leakage, leaks the phenomenon of vacuum, needs often to change sealing ring, affects manufacturing schedule.
Utility model content
Utility model object: for the problems referred to above, the purpose of this utility model is to provide a kind of filter upper flap leak-proof sealing structure, convenient installation, Leakage prevention, the service life of improving sealing ring.
Technical scheme: a kind of filter upper flap leak-proof sealing structure, comprise upper flap, filter housings, be arranged on the sealing ring in described upper flap, described filter housings top edge is also provided with flange outward.
Described flange width is greater than described sealing ring width.
Described flange upper surface flushes with described filter housings top edge.
Beneficial effect: compared with prior art, the utility model has the advantages that by increasing flange at filter housings top edge, thereby increase the sealing contact surface of sealing ring, while making upper flap closing lid on housing, can reach good sealing effectiveness, avoid leakage, leak vacuum, in the service life of having improved sealing ring, also reduced the difficulty that contraposition is installed.
Accompanying drawing explanation
Accompanying drawing 1 partly cuts open structural representation for the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in drawings, a upper flap leak-proof sealing structure, comprises upper flap 1, filter housings 2, sealing ring 3, flange 4, and sealing ring 3 is arranged in upper flap 1, it is outside that flange 4 is welded on filter housings 2 top edges, and flange 4 upper surfaces flush with filter housings 2 top edges.Flange 4 width are greater than sealing ring 3 width, when upper flap 1 closing lid is on filter housings 2, and sealing ring 3 and flange 4 upper surface sealing laminatings.
