Abstract
The open a kind of high pressure elbow of the present invention, including elbow, with the spoiler being arranged in elbow, described spoiler is arranged on the front of sweep, consistent with the bending direction of elbow, and material is impact-resistant metal material, one group can be arranged in elbow or organize spoiler more, when medium flows through spoiler, flow regime can be affected by spoiler, thus can weaken the impulsive force of elbow interior wall.The present invention is by the spoiler arranged at elbow, and fluid pressure dissipation elbow interior wall born is opened, and protects elbow interior wall, thus improves the service life of high pressure elbow.
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 outside elbow, inwall is stressed concentration effect, simultaneously
Elbow outer circumferential side due to applied environment be easily subject to abrasion；Thus be easy to send out under the erosion damage of high-pressure fluid medium
Raw perforation, 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 one or more groups spoiler.
Preferably, described spoiler is welded in elbow interior wall, integral with elbow-shaped.
Preferably, the thickness of described spoiler is less than 3mm.
Preferably, the material of described spoiler is impact-resistant metal material.
Preferably, described spoiler is with the consistent bent plate of elbow bending direction.
Preferably, described spoiler is arranged on the fluid inflow end of elbow.
Preferably, spoiler is installed at 1/4～1/2 height of elbow.
The beneficial effects of the present invention is:
The present invention, by the spoiler arranged inside elbow, makes medium before by elbow, has been formed to curved
Flow-disturbing direction inside Tou, when by elbow, will weaken the impulsive force of inwall outside elbow, be greatly reduced high pressure
The fluid impact to elbow interior wall, such that it is able to increase the service life of elbow.
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 2-spoiler
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 described elbow 1 is provided with one or more groups and disturbs
Stream plate 2.
Concrete, described spoiler 2 is welded in elbow interior wall, integral with elbow-shaped.
In order to not affect the flow velocity of fluid media (medium), the thickness of described spoiler 2 is less than 3mm.
The material of spoiler 2 is impact-resistant metal material, can improve service life.
Spoiler 2 is with the consistent bent plate of elbow bending direction, and spoiler 2 is arranged on the fluid of elbow and flows into end；Make
Fluid media (medium) before by elbow, formed the flow-disturbing direction to inner side of elbow, when by elbow, to elbow outside
The impulsive force of side inwall will weaken, and is greatly reduced the high-pressure fluid impact to elbow interior wall.
Described spoiler 2 is installed at 1/4～1/2 height of elbow, as it can be seen, be at 1/2, spoiler can move down,
To reduce the high-pressure fluid impulsive force to elbow interior wall.
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, by the spoiler arranged inside elbow, make medium by curved
Before Tou, form the flow-disturbing direction to inner side of elbow, before medium stream is by elbow, is the formation of bending flowing
Direction, when by elbow, the impulsive force of inwall outside elbow will be weakened by fluid, is greatly reduced high-pressure fluid to curved
The impact of head inwall, such that it is able to increase the service life of elbow.
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.
