Abstract
The open a kind of high pressure elbow of the present invention, including elbow, the inwall of described elbow is provided with the impeller inducer for eliminating part stress, and described impeller inducer is set to many groups, and the radial dimension that described impeller inducer is in elbow is elbow radial dimension of 1/4～1/2.Described impeller inducer interlocks and uniform intervals layout along the upper and lower surface of elbow interior wall.Arbitrary group of impeller inducer is equipped with evenly spaced 3～8 blades；Described blade uses impact-resistant metal material.The outer circumferential side of described elbow is provided with thickened wear-resisting.High-pressure fluid medium, by arranging impeller inducer in elbow, is played orderly elicitation effect by the present invention, assume responsibility for the part stress that high-pressure fluid medium washes away, and beneficially the uniform of medium circulates；Simultaneously by setting up thickened wear-resisting at elbow outer circumferential side, also further increase the service life of the present invention.
Description
Technical field
The invention belongs to high-pressure pipe member technical field, be specifically related to a kind of high pressure elbow.
Background technology
Elbow, as pipe fitting, conduit coupling, is used to change pipeline pumped (conveying) medium flow direction；Elbow is that circulation is situated between
Matter corner, is the weak link of whole pipeline；Concrete, that elbow interior wall is stressed concentration effect, simultaneously curved
The outer circumferential side of head is easily subject to abrasion due to applied environment；Thus be easy to wear under the erosion damage of high-pressure fluid medium
Hole, leak and the accident such as cracking, therefore there is serious potential safety hazard.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of simple in construction, can reduce elbow internal stress,
Increase elbow service life, reduce the high pressure elbow of potential safety hazard.
For achieving the above object, present invention employs techniques below scheme:
A kind of high pressure elbow, including elbow, the inwall of described elbow is provided with the impeller inducer for eliminating part stress,
Described impeller inducer is set to many groups, and the radial dimension that described impeller inducer is in elbow is elbow radial dimension of 1/4～1/
2。
Preferably, described impeller inducer interlocks and uniform intervals layout along the upper and lower surface of elbow interior wall.
Preferably, arbitrary group of impeller inducer is equipped with evenly spaced 3～8 blades.
Further, described blade uses impact-resistant metal material.
Preferably, described impeller inducer radial dimension in elbow is elbow radial dimension of 1/3.
Preferably, described impeller inducer is rotating to be fixed on quarter butt, and quarter butt is welded in elbow interior wall.
Preferably, the outer circumferential side of described elbow is provided with thickened wear-resisting.
Preferably, the two ends of described elbow have plumb joint respectively.
The beneficial effects of the present invention is:
High-pressure fluid medium, by arranging impeller inducer in elbow, is played orderly elicitation effect, assume responsibility for by the present invention
The part stress that high-pressure fluid medium washes away, and beneficially the uniform of medium circulates；Simultaneously by adding in elbow outer circumferential side increase
Thick wearing layer, also further increases the service life of the present invention.
Accompanying drawing explanation
Fig. 1 is the structure schematic diagram of the present invention.
In figure, the implication of label symbol is as follows:
1-elbow 10-thickened wear-resisting 2-impeller inducer 20-blade
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the present invention is clearly and completely retouched
State.Following example are only used for clearly illustrating technical scheme, and can not limit the guarantor of the present invention with this
Protect scope.
As it is shown in figure 1, be a kind of high pressure elbow, including elbow 1, the inwall of elbow 1 is provided with for eliminating part stress
Impeller inducer 2, impeller inducer 2 is set to many groups, and the radial dimension that impeller inducer 2 is in elbow 1 is that elbow is radial dimension of
1/4～1/2 to ensure that impeller will not hinder the smooth circulation of fluid media (medium) while undertaking part stress；The periphery of elbow 1
Side is provided with thickened wear-resisting 10.Plumb joint is had respectively at the two ends of elbow 1.
As one preferred embodiment, the impeller inducer 2 radial dimension in elbow 1 is elbow radial dimension of 1/
3.Wherein, impeller inducer 2 is rotating to be fixed on quarter butt, and quarter butt is welded in elbow interior wall (invisible in figure).
Wherein, impeller inducer 2 interlocks and uniform intervals layout along the upper and lower surface of elbow interior wall, will not produce eddy current, make
Fluid media (medium) circulates steadily, does not cause the situation that flow velocity is too fast or the slowest.
Arbitrary group of impeller inducer 2 is equipped with evenly spaced 3～8 blades 20, and the number of blade can be according to the chi of elbow
Little progress Row sum-equal matrix, to realize current stabilization.And blade 20 uses impact-resistant metal material, increase service life.
Below in conjunction with the accompanying drawings the structural principle of the present invention is described further.
When fluid media (medium) flows through elbow 1 of the present invention, impeller inducer 2 is driven to rotate under the high pressure effect of fluid, phase
The meeting answered drives the segment fluid flow medium of elbow interior wall to concentrate to the central part of elbow, that is, be assume responsibility for by impeller inducer
Part stress, therefore can reduce the scouring force to elbow interior wall.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and deformation, these improve and deformation
Also should be regarded as protection scope of the present invention.
