Abstract
The present invention 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.Function of the invention 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 invention belongs to filter technology fields, and in particular to a kind of high pressure resistant light-weighted small flow resistance filter core, it is especially suitable
For filtering the liquid-working-mediums such as 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.
Summary of the invention
To solve the above problems, the present invention provides a kind of high pressure resistant light-weighted small flow resistance filter core, filtering accuracy meets
It is required that operating pressure is high, light-weight, flow resistance is small under the conditions of metered flow.
To reach above-mentioned target, technical scheme is as follows:
One end welding of a kind of high pressure resistant light-weighted small flow resistance filter core, including connection end, filter cylinder and water conservancy diversion conehead, filter cylinder is led
The other end of flow cone head, filter cylinder is welded to connect end；The water conservancy diversion conehead is cone, is in cone inside water conservancy diversion conehead
Chamber；The filter cylinder is successively sintered by protective net, strainer, skeleton three-decker from outside to inside, the mesh of protective net and skeleton
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 present invention 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 the stream for shunting and generating
Resistance reduces weight and increases.The filter cylinder other end and connection end are welded to connect.The mesh of protective net is greater than sieve meshes.Skeleton
The mesh of net is laser processing, is greater than the sieve meshes.After being sintered, being welded into filter cylinder, working media divides under strainer effect
From impurity.Strainability is uninfluenced after the strainer is sintered, is welded, and reduces product flow resistance.The protective net, skeleton it is auxiliary
It helps, filter cylinder crushing strength improves, and internal unbraced structure reduces product weight.It is strong that the skeleton improves filter core conquassation
Degree and welding usability, can be big with filter area, reduces product flow resistance.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of filter cylinder in the present invention.
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 present invention 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 embodiments of the present invention and the technical principle used, any to be based on technical solution of the present invention
On the basis of equivalent transformation, all belong to the scope of protection of the present invention within.
Unspecified part of the present invention is known to the skilled person technology.
