Abstract

The utility model relates to an elbow, which is suitable for being used at the corner of a pipeline which is more badly worn in the process of conveying ash and powder, and can effectively reduce the wear of the elbow of the pipeline. The novel wear resisting elbow comprises flanges (1), an elbow inner pipe (2), an elbow outer pipe (3) and cement (4), and is characterized in that an elbow with same curvature and larger diameter (an elbow with large diameter can be chosen according to the actual situation) is sleeved outside an ordinary elbow, and the cement is filled between the two elbows; the flanges are welded on the two ends of the elbows after the cement is set to form a wear resisting elbow, and the nominal diameter is the nominal diameter of the inner pipe. The utility model not only increases the wear resistance and effectively lowers the cost, but also saves the replacement time of the elbow.

Description

The novel wear resistant elbow

Technical field

The utility model is a kind of wear-resistant bend, and in particular, the utility model is the wear-resistant bend that is applicable to the more serious pipeline corners of wearing and tearing such as defeated ash, defeated powder.

Background technique

In smelter, often need by the pulverous solid matter of line transportation, as the dedusting ash in blast furnace pulverized coal conveying, blast furnace gas dry dust removal system etc.These pipelines often use wear-resistant bend in the corner, yet more serious even wear-resistant bend also weares and teares, the consumption of elbow is bigger, and frequently changing elbow has influenced produce continuous, has also increased cost.

Summary of the invention

The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of novel wear-resistant bend is provided, and it can reduce the loss of the channel bend of conveying solid substance powder, has also reduced the engineering time of equipment.

The technical solution of the utility model is summarized as follows:

A kind of novel wear resistant elbow includes: pipe, elbow outer tube, cement in flange, the elbow.

Characteristics of the present utility model are filling concrete between the elbow in two different-diameters, identical curved footpath, pipe and outer pipe bend in can selecting flexibly according to the internal diameter of ash conveying pipe, and welding upper flange in two ends has just been formed wear-resistant bend.

Compared with prior art, the beneficial effects of the utility model are as follows:

1. filling concrete between two elbows is compared with two elbows, has increased wear resistance.

2. reduce the loss of elbow, effectively reduced cost.

3. the replacing number of times owing to elbow reduces, so saved engineering time.

4. preparation process is simple, and cost is lower.

Description of drawings

Fig. 1 is the plan view of wear-resistant bend;

Fig. 2 is the left view of wear-resistant bend;

Fig. 3 is the A-A sectional view of wear-resistant bend.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

In the drawings, can be in identical curved footpath of cover, common elbow outside, elbow (can select large diameter elbow) that diameter is bigger according to actual conditions, filling concrete between two elbows, Deng solidifying back two ends welding upper flange, can be used as wear-resistant bend and use, its nominal diameter is the nominal diameter of interior pipe.

Claims

1, a kind of novel wear resistant elbow is to be made of pipe, elbow outer tube, cement in flange, the elbow, it is characterized in that, two elbows that vary in size are nested together and form an elbow, and flange plays fixation, and cement is packing.

2, be characterised in that elbow two ends welding upper flange by the described novel wear resistant elbow of claim 1.

3, be characterised in that at two different-diameters by the described wear-resistant bend of claim 1 but filling concrete between the common elbow in identical curved footpath.
