Description
Technical field
The utility model belongs to tube head connecting piece field, and in particular to be a kind of ceramic wear-resisting bend.
Background technology
In some high temperature of existing industrial circle, the especially industrial circle such as petrochemical industry, thermoelectricity desulfurization, nuclear power station, power station
The pipeline being on active service under high pressure, corrosive wear environment, abrasion is easily produced under half admittedly half gas or half erosion for consolidating half liquid or full liquid
Make metallic walls thinning, especially be highly prone to wear at the curved arc of pipeline elbow, its degree of wear be straight pipe-line several times with
On, industrial pipeline leakage accident of the whole world almost more than percent 90 all occurs from elbow, potential safety hazard be present, endangers people
Body safety.
Existing elbow is made of mild steel, steel alloy etc. more, but the hardness of these materials, which is difficult resistance, tells water
The impact of stream, and tube wall can also be formed in flow at high speed doped with some granule foreigns, granule foreign in current
Huge impulsive force, so as to damage, reduce the Stability Analysis of Structures of elbow.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of impulsive force that can reduce current, enable to
What the granule foreign adulterated in current crushed, the ceramic wear-resisting bend of intensity height and service life length.
To achieve the above object, the technical solution adopted in the utility model is a kind of ceramic wear-resisting bend, including import department
And export department, bending section is connected between import department and export department, its structural feature is that bending section includes relief portion and buffer part,
Relief portion is tubaeform setting, and buffer part seamlessly transits setting, buffer part inner surface by relief portion to export department's large diameter circular arc
Provided with the dashpot provided with the progressive setting of spiral, the side wall of dashpot is provided with the protuberance that zigzag is set.
As further improvement of the utility model, the wall thickness of bending section is 2 times of the wall thickness of import department and export department.
As further improvement of the utility model, import department, export department and bending section are integrally formed.
As further improvement of the utility model, copper alloy is equipped with the inwall of import department, export department and bending section
Layer.
As further improvement of the utility model, the surface of copper alloy layer is provided with fine and closely woven kick.
As further improvement of the utility model, import department, export department and bending section are made by alumina powder, wall
Inside it is wound with alloy-steel wire.
The beneficial effects of the utility model are：It is reasonable in design, it is simple in construction, current can be reduced when flowing through elbow to curved
The impulsive force of head, reduces the destruction to elbow, moreover, impurity particle present in fluid can be crushed, further reduces
Infringement to elbow, add the service life and security of elbow.

Embodiment
Explanation is further explained to the utility model below in conjunction with the accompanying drawings, but does not limit protection model of the present utility model
Enclose.
As shown in Figure 1 to Figure 2, a kind of ceramic wear-resisting bend, including import department 1 and export department 2, import department 1 and export department 2
Between connect bending section 3, described bending section 3 includes relief portion 4 and buffer part 5, and relief portion 4 is tubaeform setting, buffer part 5
Setting is seamlessly transitted by relief portion 4 to the large diameter circular arc of export department 2, the inner surface of buffer part 5 is provided with provided with the progressive setting of spiral
Dashpot 6, after current are flowed into by import department 1, because relief portion 4 is tubaeform setting, in the unit area of current now
Pressure can reduce, then by the buffering of buffer part 5, because dashpot 6 is the progressive setting of spiral, current are in dashpot 6
Mixing impact can be formed after interior flowing, causes the counteracting of water flow impact pressure, further reduces the destructive power of current, and is buffered
The side wall of groove 6 is provided with the protuberance 7 that zigzag is set, can be with protrusion when the doping particle in current flows with current
Portion 7 collides, and crush doping particle by constantly collision, described import department 1, export department 2 and bending section 3
Copper alloy layer 8 is equipped with inwall, the surface of described copper alloy layer 8 is provided with fine and closely woven kick, and does not have also in current
When flowing into bending section 3, it becomes possible to friction and collision occurs with kick, more reduces the destructive power of doping particle.
The wall thickness of described bending section 3 is 2 times of the wall thickness of import department 1 and export department 2；Add the anti-broken of bending section 3
Bad intensity, improve service life.
Described import department 1, export department 2 and bending section 3 is integrally formed；Increase the stability of seal and structure.
Described import department 1, export department 2 and bending section 3 is made by alumina powder, and steel alloy is wound with wall
Silk；Toughness and intensity can be increased.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
