Abstract
The utility model relates to a kind of high pressure resistant light-weighted small flow resistance filter core, including connection end, filter cylinder and water conservancy diversion conehead, water conservancy diversion conehead is welded in one end of filter cylinder, and the other end of filter cylinder is welded to connect end；The water conservancy diversion conehead is cone, is conical cavity inside water conservancy diversion conehead；The filter cylinder is successively sintered by protective net, strainer, skeleton three-decker from outside to inside；The inside of the connection end is equipped with the through-hole connecting with filter cylinder inner cavity.The function of the utility model is filtering liquid-working-medium, and when pipeline work, medium is filtered through filter cylinder and flowed out by connection end after the shunting of water conservancy diversion conehead, and the impurity in working media plays catharsis by filter cylinder blocking, separation.
Description
Technical field
The utility model belongs to filter technology field, and in particular to a kind of high pressure resistant light-weighted small flow resistance filter core, especially
It is suitable for the liquid-working-mediums such as filtering aviation kerosine, high density hydrocarbon.
Background technique
Filter core is widely applied in engine liquid channel system.With the continuous development of technology, operating pressure increases, flow resistance refers to
Mark it is harsh so that filter core weight increase, it is difficult to meet product index requirement.Filter core in the prior art, weight is larger or flow resistance
Larger, weight and flow resistance performance can not get both.
Utility model content
To solve the above problems, the utility model provides a kind of high pressure resistant light-weighted small flow resistance filter core, filtering accuracy
It meets the requirements, operating pressure is high, and light-weight, flow resistance is small under the conditions of metered flow.
To reach above-mentioned target, the technical solution of the utility model is as follows:
A kind of high pressure resistant light-weighted small flow resistance filter core, including connection end, filter cylinder and water conservancy diversion conehead, one end weldering of filter cylinder
Water conservancy diversion conehead is connect, the other end of filter cylinder is welded to connect end；The water conservancy diversion conehead is cone, is circular cone inside water conservancy diversion conehead
Shape inner cavity；The filter cylinder is successively sintered by protective net, strainer, skeleton three-decker from outside to inside, protective net and skeleton
Mesh diameter is greater than the mesh diameter of strainer；The inside of the connection end is equipped with the through-hole connecting with filter cylinder inner cavity.
The protective net, strainer, skeleton are roll type structure, and three forms cylindrical filtration cartridges.
The outer surface of the water conservancy diversion conehead smoothly transits with cylindrical filtration cartridges.
The connection end is equipped with piston type seal groove structure.
The filter cylinder and connection end and water conservancy diversion conehead use grafting welding structure.
The utility model compared with prior art the utility model has the advantages that
Working media shunts under the effect of water conservancy diversion conehead in pipeline.The cone angle of the water conservancy diversion conehead can reduce shunting and generate
Flow resistance, reduce weight increase.The filter cylinder other end and connection end are welded to connect.The mesh of protective net is greater than sieve meshes.
The mesh of skeleton is laser processing, is greater than the sieve meshes.After being sintered, being welded into filter cylinder, working media is acted in strainer
Lower separation impurity.Strainability is uninfluenced after the strainer is sintered, is welded, and reduces product flow resistance.The protective net, skeleton
Auxiliary, filter cylinder crushing strength improves, and internal unbraced structure reduces product weight.The skeleton improves filter core pressure
Intensity of bursting and welding usability, can be big with filter area, reduces product flow resistance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of filter cylinder in the utility model.
In figure, 1, connection end, 2, filter cylinder, 3, water conservancy diversion conehead, 4, protective net, 5, strainer, 6, skeleton.
Specific embodiment
Referring to the drawings, in conjunction with specific embodiments, the utility model is described in detail.
Embodiment
As shown, a kind of high pressure resistant light-weighted small flow resistance filter core, including connection end 1, filter cylinder 2 and water conservancy diversion conehead 3,
Water conservancy diversion conehead 3 is welded in one end grafting of filter cylinder 2, and the other end grafting of filter cylinder 2 is welded to connect end 1；The water conservancy diversion conehead is
Cone, water conservancy diversion conehead inside is conical cavity, and outer surface and the cylindrical filtration cartridges of water conservancy diversion conehead smoothly transit；The filter cylinder
It is successively sintered from outside to inside by protective net 4, strainer 5,6 three-decker of skeleton, the mesh diameter of protective net and skeleton is greater than
The mesh diameter of strainer；The connection end is equipped with piston type seal groove structure, and the inside of connection end is equipped with and filter cylinder inner cavity
The through-hole of connection.
Skeleton 6 is formed after laser boring by steel band, and the skeleton 6 is sequentially stacked and sintered into strainer 5 and protective net 4
One, through edge rolling butt welding.Keep protective net in 2 outer surface of filter cylinder.After connection end 1, filter cylinder 2, water conservancy diversion conehead 3 assemble, point
It Han Jie not filter cylinder 2 and 3 abutment joint of water conservancy diversion conehead and 2 abutment joint of connection end 1 and filter cylinder.
When working media flows through water conservancy diversion conehead 3, it is split under cone angle effect.Under pressure is used in liquid channel system, work
Make medium and successively penetrates protective net 4, strainer 5, skeleton 6.
4 mesh diameter of protective net is greater than 5 mesh diameter of strainer.Flow resistance when working media penetrates protective net 4, with the generation of strainer 5
It compares, protective net 4, which generates flow resistance, to be ignored.When working media penetrates strainer 5, the impurity in working media is blocked, separates,
Form satisfactory cleaning medium.6 mesh diameter of skeleton is greater than 5 mesh diameter of strainer.Working media penetrates skeleton 6
When, the flow resistance generated with strainer 5 compares, and the flow resistance that skeleton 6 generates can be ignored.Finally, clean working media is from even
The outflow of end 1 is connect, is used for liquid channel system.
In the case where protective net 4 and skeleton 6 act on, the crushing strength and bending performance of filter cylinder 2 are improved, in connection end 1
Under supporting with water conservancy diversion conehead 3, the crushing strength of filter cylinder 2 is improved.Without being further added by support in filter cylinder 2.
The above is specific embodiment of the utility model and the technical principle used, any to be based on the utility model
Equivalent transformation on the basis of technical solution, belongs within the protection scope of the utility model.
The utility model unspecified part is known to the skilled person technology.
