Abstract
The open a kind of high pressure elbow of the present invention, wherein the outside inwall of elbow is provided with buffering deflector, described buffering deflector along the medium of elbow flow to evenly spaced be provided with multistage；Arbitrarily first-level buffer deflector is set to 10 °～15 ° with the angle of tube wall, and the 1/5～1/4 of a length of elbow radial diameter of slow deflector, the described deflector that rushes is set to straight plate.The present invention, by the buffering deflector arranged on inwall outside elbow, reduces medium when bend pipe flows to the impulsive force of inwall outside bend pipe to the eddy current produced during media flow, 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 buffering deflector；Described buffering deflector edge
The medium of elbow flow to evenly spaced be provided with multistage；Outside described buffering deflector and elbow, the angle of inwall is set to 10 °
～15 °.
Preferably, described buffering deflector is welded in elbow interior wall.
Preferably, a length of elbow radial dimension of 1/5～1/4 of any first-level buffer deflector.
Preferably, any first-level buffer deflector is impact-resistant metal material.
Preferably, any first-level buffer deflector is set to straight plate.
Preferably, between described multi-buffer deflector, evenly spaced distance is the 1/8～1/4 of elbow radian size.
The beneficial effects of the present invention is:
The present invention arranges buffering deflector by inwall outside elbow, and direct impulsive force during media flow is transferred to
On buffer board, meanwhile, buffer board makes medium produce eddy current with the angle of elbow interior wall, and this eddy current also can reduce medium to inwall
Impulsive force, 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-buffers deflector
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 buffering deflector 2；
Described buffering deflector 2 along the medium of elbow flow to evenly spaced be provided with multistage；In outside described buffering deflector 2 and elbow
The angle of wall is set to 10 °～15 °.
Concrete, described buffering deflector 2 is welded on elbow 1 inwall.
The arbitrarily a length of elbow radial dimension of 1/5～1/4 of first-level buffer deflector 2, and arbitrarily first-level buffer water conservancy diversion
Plate 2 is set to straight plate；To ensure to form preferable venturi effect.
Arbitrarily first-level buffer deflector 2 is impact-resistant metal material, strengthens service life.
Between described multi-buffer deflector 2, evenly spaced distance is the 1/8～1/4 of elbow radian size, and interval is all
Even further ensure venturi effect, to reduce the medium impulsive force to inwall.
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, radially first the impulsive force of inwall outside elbow can be buffered and lead
Stream plate undertakes, and at the buffering deflector angle space with inwall, flow media produces eddy current, this eddy current relative medium flow velocity pair
The impact of inwall is much smaller, thus, when medium flows in elbow, the impulsive force of generation is weakened, and protects elbow
Inwall, extends the service life of high pressure 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.
