Abstract
The utility model belongs to the technical field of pipe connectors, in particular to a composite connector of an abrasion-proof bent pipe and an abrasion-proof tee pipe. The connector comprises a pipe connector body, a casing arranged on the outer wall of the pipe connector body, and an abrasion-proof layer arranged between the pipe connector body and the casing, and is characterized in that a T-type rib is arranged on the abrasion-proof layer arranged between the pipe connector body and the casing, a hole is formed on the casing at the part provided with the T-type rib, one end of the T-type rib and the pipe connector body are welded, and the other end of the T-type rib and the casing are in plug welding through the hole formed on the casing. Compared with the prior art, the utility model has the advantages of reasonable structure, increases the adhering force between the abrasion-proof layer and the pipe connector body with the T-type rib in the abrasion-proof layer, effectively improves the compression resistance capacity of pipes, and prevents the phenomena of explosion and easy deformation after the connector is mounted on the pipe of which the diameter is greater than Phi 800mm.
Description
Technical field
The utility model belongs to the conduit coupling technical field, particularly a kind of composite-material abrasive bend pipe and wear-resisting three-way pipe attaching parts.
Background technology
Industrial employed cleaning shaft and transport the mineral pipe material such as in metallurgy, mine at present, ubiquity in process of production the dust that produces or mineral material hardness height, than great, be with corner angle, have defective such as great chiseling property of mill, the tail of the tail of the broken factory in mine, ore dressing plant, pelletizing plant, coke-oven plant, Metallurgical Factory, sintering plant, finished product, pelletizing plant for example, the dust that production processs such as base material produce, when handling this type of dust, the speed of dusty gas is up to 18-22m/s in the cleaning shaft, gas dust content 10-20g/m3.The high speed dust-contained airflow constantly washes away pipeline, especially the wearing and tearing of bend pipe and three-way pipe position are comparatively seriously outstanding in conduit coupling, cause pipeline can not normally move work, the pipeline mill leaks the service life that wear damage has influenced pipeline, bend pipe and three-way pipe position grind Lou to wear and tear too early in the conduit coupling has not only increased the maintenance engineering amount, during maintain and replace and waste time and energy, waste material during maintenance, fund are bigger, and pipeline work efficiency effect is greatly reduced.Solve above-mentioned existing weak point for overcoming, people begin to develop wear-resisting attaching parts, Chinese patent ZL 99 2 24133.2 discloses a kind of " pipeline composite-material abrasive bend pipe and wear-resisting three-way pipe attaching parts ", its structure is that the lateral wall welded and installed at conduit coupling has body skin, has wearing layer between conduit coupling lateral wall and body skin.This wear-resisting attaching parts has improved the service life of conduit coupling effectively, and general being suitable for and the pipeline of diameter less than φ 800mm is if but just make pipeline generation explosion and yielding easily when diameter uses on greater than the pipeline of φ 800mm.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reasonable in design is provided, and avoids pipeline generation explosion and yielding phenomenon, the pipeline composite-material abrasive bend pipe of long service life and wear-resisting three-way pipe attaching parts.
According to pipeline composite-material abrasive bend pipe of the present utility model and wear-resisting three-way pipe attaching parts, comprise the conduit coupling body, be located at the housing of conduit coupling body outer wall and be located at the conduit coupling body and the outer wall housing between wearing layer, it is characterized in that on mill layer anti-between conduit coupling body and the outer wall housing, being provided with the T-shape muscle, on the outer wall housing that is provided with T-shape muscle place, have hole, described T-shape muscle one end and the welding of conduit coupling body, hole and the outer wall housing plug welding of the other end by having on the outer wall housing.
Described conduit coupling body is bend pipe or three-way pipe.
The utility model compared with prior art, have the following advantages and effect: it is rational in infrastructure, owing in wearing layer, be provided with the T-shape muscle, increased the adhesive ability between wearing layer and the conduit coupling body, increased the compressive property of pipeline effectively, avoided after diameter is installed attaching parts on greater than the pipeline of φ 800mm, producing explosion and yielding phenomenon.
Description of drawings
Fig. 1 is a bend pipe shape attaching parts overall structure partial schematic sectional view of the present utility model.
Fig. 2 is three-way pipe shape attaching parts of the present utility model part sectional view.
Fig. 3 is the B portion enlarged drawing of the utility model Fig. 1.
The specific embodiment
As Fig. 1, shown in 3, according to pipeline composite-material abrasive bend pipe of the present utility model and wear-resisting three-way pipe attaching parts, comprise conduit coupling body 1, be located at plumbing connection body 1 outer wall housing 3 and be located at conduit coupling body 1 and outer wall housing 3 between wearing layer 2, it is characterized in that on mill layer 2 anti-between conduit coupling body 1 and the outer wall housing 3, being provided with T-shape muscle 4, on the outer wall housing 3 that is provided with T-shape muscle 4 places, have hole, described T-shape muscle 4 one ends and conduit coupling body 1 welding, the other end and hole and outer wall housing plug welding 5 by having on the outer wall housing 3.Its T-shape muscle has increased the adhesive ability between wearing layer and the conduit coupling body.
Described conduit coupling body 1 is bend pipe or three-way pipe.
Fig. 2 shows the structural representation that conduit coupling is the three-way pipe shape, on mill layer 2 anti-between conduit coupling body 1 and the outer wall housing 3, be provided with T-shape muscle 4, on the outer wall housing 3 that is provided with T-shape muscle 4 places, have hole, 1 welding of described T-shape muscle 4 one ends and conduit coupling body, the other end with by having hole and outer wall housing plug welding 5 on the outer wall housing 3.Wearing layer 2 of the present utility model mixes institute by glass-cermic powder, diluent sodium silicate, curing agent sodium fluosilicate and alloy steel fiber and forms.This structure has increased the resistance to abrasion of conduit coupling, avoids conduit coupling explosion and yielding phenomenon, improves conduit coupling service life.The utility model is specially adapted to 400 ℃ of gas temperatures, gas flow rate 18-22m/s, gas dust content 10-20g/m3, the mineral pipe material that pipe diameter transports greater than metallurgical cleaning shaft and the mine of φ 800mm.The utility model also can be made four-way or five-way pipe.
