Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant elbows, in particular to a wear-resistant pipe elbow that is easy to connect. Background Art

[0002] Wear-resistant mining pipe elbow is a kind of pipeline connector used in mining, metallurgy, electric power and other fields. It mainly plays the role of changing the direction of the pipeline. In mining pipelines, elbows are usually used to extend the pipeline in different directions to adapt to the complex structure and working environment inside the mine.

[0003] A novel wear-resistant elbow for mining with publication number CN210266351U comprises an elbow body, wherein both ends of the elbow body are respectively provided with an inlet flange and an outlet flange; the utility model, through the joint action of the first wear-resistant layer, the second wear-resistant layer and the flow limiting plate, the flow limiting plate slows down the impact force of the material entering from the inlet flange on the inner wall of the elbow body, reduces the degree of wear of the inner wall of the elbow body by the impact force, and under the joint action of the protective plate and the spring, when encountering external impact, the protective plate is pressed on the spring under the action of the force generated by the external impact, and the impact generated by the impact is reduced under the action of the spring rebound. The force protects the elbow body and prevents the elbow body from being deformed by external impact force, causing the flow rate and flow rate of the material on the inner wall of the elbow body to change, and generating impact force on the pipe wall of the elbow body to protect the elbow body. However, due to the curved structure of this wear-resistant elbow, the opening of the limiting plate that squeezes the spring outward cannot be completely sealed with the elbow body, and external impurities, moisture, etc. entering the pipeline will block it and affect the normal operation of the elbow. At the same time, the suspended setting of the protective plates at both ends of the pipe elbow makes it inconvenient to connect or fix the elbow with other pipe parts, resulting in poor sealing when the whole is used.

[0004] In view of the above problems, a wear-resistant pipe elbow which is easy to connect is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a wear-resistant pipe elbow that is easy to connect, which solves the problem that the existing pipe elbow in the background technology has a curved structure, so that the opening of the flow limiting plate that squeezes the spring outward cannot be completely sealed with the elbow body, and external impurities, moisture, etc. enter the pipeline, which will block and affect the normal operation of the elbow. At the same time, the suspended setting of the protective plates at both ends of the pipe elbow makes it inconvenient to connect or fix the elbow with other pipe parts, resulting in poor sealing when the whole is used.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant pipe elbow that is easy to connect, including a mining elbow, a sealing joint is clamped on one side of the mining elbow, a sealing swivel is sleeved on the sealing joint for extrusion and fixation, the mining elbow includes a fixed elbow, side joints fixedly arranged at both ends of the fixed elbow, tungsten carbide coatings are arranged on the inner and outer sides of the fixed elbow, a large gasket is arranged inside the side joint, the sealing joint includes a connecting pipe with the large gasket extruded, the sealing swivel is movably sleeved on the connecting pipe and rotates forward along the side joint, and a small gasket is clamped on one side of the connecting pipe.

[0007] Preferably, the large gasket matches the shape of the built-in bayonet of the side joint.

[0008] Preferably, the side joint comprises a fixing ring fixedly arranged at both ends of the fixed elbow, and a threaded groove is formed at an outer end of one side of the fixing ring.

[0009] Preferably, a limiting ring is fixedly provided on the connecting pipe, and a gasket groove is opened on one side of the limiting ring.

[0010] Preferably, the small gasket is engaged in the gasket groove.

[0011] Preferably, the sealing swivel comprises a sleeve ring arranged on a sleeve pipe, and a limiting groove is provided inside the sleeve ring.

[0012] Preferably, a built-in thread is provided inside one side of the collar.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model provides a wear-resistant pipe elbow that is easy to connect. By setting a tungsten carbide coating in a fixed elbow, the tungsten carbide coating is set on both the inner and outer sides of the fixed elbow. The tungsten carbide coating is a wear-resistant material, which improves the hardness and wear resistance of the surface and interior of the elbow.

[0015] 2. The utility model provides a wear-resistant pipe elbow that is easy to connect. By squeezing the large gasket and the small gasket, the mining elbow and the sealing joint can be sealed and fixed by rotating and squeezing the sealing swivel, preventing external impurities, moisture, etc. from entering the pipeline and blocking the normal operation of the elbow. At the same time, the inner diameters of the connection between the fixed elbow and the side joint are the same, which will not affect the transportation of materials inside the mining elbow. The existing pipe elbow is solved because the wear-resistant elbow is a curved structure, which makes it impossible to completely seal the opening of the flow limiting plate to squeeze the spring outward and the elbow body, and external impurities, moisture, etc. enter the pipeline, which will block the normal operation of the elbow.
