Description
Technical field
It the utility model is related to a kind of Non-return filter.
Background technology
In pipe installation process, it is often necessary to check-valves is installed to prevent medium from flowing backwards, while in order to prevent in medium
Impurity some equipment are caused damage to generally require filter are installed before equipment.At the scene list is generally required in installation process
Solely installation check-valves and filter, while separated maintenance is also required to when the later stage maintaining and safeguarding, installation is safeguarded all cumbersome.
Utility model content
The purpose of this utility model is to provide a kind of installation and safeguards more convenient Non-return filter.
Realizing the technical scheme of the utility model purpose is：A kind of Non-return filter, including filter body；The filtering
Device body includes snout cavity, the filter chamber of sidepiece and the outlet plenum on top of bottom；The snout cavity is via filter chamber with going out
Oral cavity connects；Filter core is provided with the filter chamber；The check plate for separating outlet plenum up and down is provided with the outlet plenum, on check plate
End is provided with the non-return cylinder of tubular structure；The side wall of the non-return cylinder is provided with multiple outflow ports, on the check plate in non-return cylinder
Provided with the non-return hole run through up and down；The inside of the non-return cylinder is provided with spherical valve core, and the diameter of spherical valve core is less than in non-return cylinder
Footpath and it is more than non-return hole internal diameter.
The check plate is the sunk type slope structure gradually collapsed to centre by outer.
The outer surface of the spherical valve core is provided with elastic layer.
Above-mentioned technical proposal is employed, the utility model has following beneficial effect：(1) the utility model structure letter
It is single, easy to use, have non-return and filtering function concurrently, avoid the blocking of pipeline and the adverse current of medium and meanwhile reduce installation and
The cost of maintenance.
(2) retaining element in the utility model eliminates spring part commonly used in the prior art, avoids spring part and exists
The problem of being followed the string during long-term use, improve the service life of retaining element.
(3) check plate of the present utility model is the sunk type slope structure gradually collapsed to centre by outer, is more conducively situated between
Spherical valve core is tumbled to non-return hole site after matter stops flowing.
Brief description of the drawings
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model, wherein
Fig. 1 is structural representation of the present utility model.
Embodiment
(embodiment 1)
See Fig. 1, a kind of Non-return filter of the present embodiment, including filter body.Filter body includes entering for bottom
The outlet plenum 3 in oral cavity 1, the filter chamber 2 of sidepiece and top.
Snout cavity 1 connects via filter chamber 2 with outlet plenum 3.Filter core 4 is provided with filter chamber 2.It is provided with up and down in outlet plenum 3
Separate the check plate 5 of outlet plenum 3, the upper end of check plate 5 is provided with the non-return cylinder 6 of tubular structure.Check plate 5 is by outer to centre
The sunk type slope structure gradually collapsed.The side wall of non-return cylinder 6 is provided with multiple outflow port 6-1, the check plate 5 in non-return cylinder 6
It is provided with the non-return hole 5-1 run through up and down.The inside of non-return cylinder 6 is provided with spherical valve core 7, and the diameter of spherical valve core 7 is less than non-return
Cylinder and is more than non-return hole 5-1 internal diameters at 6 internal diameters.The outer surface of spherical valve core 7 is provided with elastic layer.
During work, fluid media (medium) enters snout cavity 1 by lower channel, then enters outlet plenum 3 by filter chamber 2, by check plate 5
On non-return hole 5-1 enter, spherical valve core 7 5-1 of non-return hole at will be got lodged in push up and open, fluid media (medium) is from the side wall of non-return cylinder 6
Multiple outflow port 6-1 exit into upper end pipeline.
Particular embodiments described above, the purpose of this utility model, technical scheme and beneficial effect are carried out to enter one
Step describes in detail, should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this
Utility model, it is all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements done etc., it all should wrap
It is contained within the scope of protection of the utility model.
