Description
Technical field
The utility model relates to a kind of filter core sealing structures.
Background technique
At present in filter core product, in rotation valve arrangement using end face seal, this rotation valve sealing structure has
Water stopping function, although there is fast and simple preferential, this end face seal structure pair without closing angle valve when changeing filter core
The size of plastic Shooting Technique, the mold accuracy of manufacture and sealing ring requires stringent, manufacture difficulty；Product size slightly becomes simultaneously
Change will result in disabler；And the structure will cause installation filter core when feel it is heavier.
Summary of the invention
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of filter core sealing structures.
The utility model is achieved through the following technical solutions:
A kind of filter core sealing structure, including joining wall base and filter element shell, set between the wall base and filter element shell
Rotation valve is set, the water hole matched with wall base is provided on the rotation valve, between the rotation valve at water hole and wall base
It is provided with cartridge type sealing ring, the internal perisporium of cartridge type sealing ring one end extends internally and has compressed part, is arranged in the compressed part
There is a holddown spring.
In the utility model embodiment, the internal perisporium of cartridge type sealing ring lower end extends internally and has compressed part, is located at pressure
Cartridge type sealing ring peripheral wall above tight portion is from bottom to top gradually to extending out.
In the utility model embodiment, be arranged on the wall base and the end face that connect of rotation valve it is fluted, in the groove
It is provided with the water pipe of crossing of protrusion, described holddown spring one end was set in water pipe periphery, the holddown spring other end and compression
Portion is connected.
In the utility model embodiment, cartridge type sealing ring periphery is provided with the sealing ring matched with recess peripheral wall.
In the utility model embodiment, the rotation valve is connected through a compacting ring with wall base.
A kind of filter core sealing structure of the utility model, has the following beneficial effects:
1, lower, manufacture difficulty reduction is required the size of wall base and cartridge type sealing ring.
2, function reliable is high, it is not easy to fail.
3, for hand without using many strength, feel is splendid when installing filter core.
Detailed description of the invention
It, below will be to institute in embodiment or description of the prior art in order to illustrate more clearly of the technical solution of the utility model
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some of the utility model
Embodiment for those of ordinary skill in the art without creative efforts, can also be attached according to these
Figure obtains other attached drawings.
Fig. 1 is the schematic diagram of state one in the utility model.
Fig. 2 is the schematic diagram of state two in the utility model.
Fig. 3 is the enlarged diagram in Fig. 2 at A.
Fig. 4 is the schematic diagram of cartridge type sealing ring in the utility model.
Fig. 5 is the schematic diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, to the technical solution in inventive embodiments carry out it is clear,
It is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
Reference book attached drawing, a kind of filter core sealing structure, including joining wall base 10 and filter element shell 20, it is described
Setting rotates valve 30 between wall base and filter element shell, is provided with the water hole 31 matched with wall base on the rotation valve, was located at
Cartridge type sealing ring 40 is provided between rotation valve at water hole and wall base, the internal perisporium of cartridge type sealing ring one end extends internally and has
Compressed part 41 is provided with a holddown spring 50 in the compressed part.
Further, the internal perisporium of cartridge type sealing ring lower end, which extends internally, compressed part, above compressed part
Cartridge type sealing ring peripheral wall makes the upper half of cartridge type sealing ring bowl-shape in one so from bottom to top gradually to extending out.
In one preferred embodiment of the utility model, it is arranged fluted 11 on the end face that the wall base is connect with rotation valve, institute
The mistake water pipe 12 that protrusion is provided in groove is stated, described holddown spring one end was set in water pipe periphery, and the holddown spring is another
One end is connected with compressed part, make in this way the lower half of cartridge type sealing ring with rotate valve and realize the contact in face, and holddown spring
Using may insure leakproofness.Further, in order to which with better seal effect, cartridge type sealing ring periphery is provided with
The sealing ring 42 matched with recess peripheral wall.
Further, the rotation valve is connected through a compacting ring 60 with wall base.
The utility model China, have one for sealing cartridge type sealing ring, be made using flexible material, the cartridge type is close
Spring is cased with inside seal, rotation valve is installed on wall base by a compacting ring.Spring force of the structure in holddown spring
Under effect, cartridge type sealing ring is contacted with rotation valve always, and sealing can be effectively ensured.The structure equally has water stopping function, tears open
It is fast and simple without closing angle valve when changing filter core.
Above disclosed is only the preferred embodiment of the utility model, certainly cannot be practical new to limit this with this
The interest field of type, therefore equivalent variations made according to the claim of the utility model still belong to the model that the utility model is covered
It encloses.
