Abstract
The utility model relates to a different-diameter rubber-lining steel casing tube expansion piece which is characterized in that an inner casing tube and an outer casing tube form a steel structure, abrasion-resistant rubber materials are lined in the steel structure to form a through-type different-diameter shell, sealing rings are arranged inside the inner casing tube and the outer casing tube, the inner casing tube and an inner casing tube flange are in an integrated structure, an outer casing tube flange and the outer casing tube are in an integrated structure, the outer casing tube is a reducer, a blocking ring is arranged in the outer casing tube, a movable flange is arranged outside the outer casing tube, and the inner casing tube and the outer casing tube are fixedly connected through limiting bolts. A press cover is arranged outside the inner casing tube and is connected with the outer casing tube flange through fastening bolts to press the sealing rings tightly, and therefore the inner casing tube and the outer casing tube are in a sealed state. The abrasion-resistant rubber materials are lined inside the inner casing tube and the outer casing tube which is the reducer. The using cycle of the different-diameter rubber-lining steel casing tube expansion piece is ten to fifteen times of an ordinary steel reducer, the service life of equipment is greatly prolonged, replacing frequency of the equipment is reduced, and using cost of the equipment is lowered.
Description
Technical field
The utility model belongs to a kind of reducing equipment that is arranged on pump discharge in slurry transportation pipeline, particularly a kind of reducing line with rubber steel casing expander.
Background technique
At present, the domestic reducing equipment that in slurry transportation pipeline, is installed in pump discharge, traditional mode is to adopt common steel reducer, owing to not serving as a contrast high-abrasive material in the common steel reducing body, do not have telescopicing performance, exist: the problems such as life cycle is short, wear-resisting property is poor, increased the replacing number of times, labor strength is large have affected manufacturing efficiency.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose provides a kind of being installed on the slurry pipeline, has wear-resisting, corrosion-resistant, life cycle long and have telescopicing performance and reduce the reducing line with rubber steel casing expander of noise performance.
The utility model reducing line with rubber steel casing expander content Description:
The utility model reducing line with rubber steel casing expander, it is characterized in that: formed by inner sleeve, inner sleeve flange, clamping bolt, gland, outer sleeve flange, seal ring, back-up ring, outer sleeve, loose flange and caging bolt, consisted of the straight-through type reducing housing of steel structure inner liner abrasive resistant rubber material by inner sleeve and outer sleeve, be provided with seal ring in inner sleeve and outer sleeve, inner sleeve and inner sleeve flange are structure as a whole; Outer sleeve flange and outer sleeve are structure as a whole, and outer sleeve is reducer, are provided with back-up ring in outer sleeve, and the outside of outer sleeve is provided with loose flange, and inner sleeve is fixedly connected with by caging bolt with outer sleeve.
Gland is arranged on the outside of inner sleeve, is connected with the outer sleeve flange by clamping bolt, and seal ring is compressed, and makes between inner sleeve and the outer sleeve and forms sealing state.
All be lined with the abrasive rubber material in the inside of inner sleeve and the inside of outer sleeve reducer.
The utility model reducing line with rubber steel casing expander, all there is the line with rubber flange flange both sides, need not to add in addition sealing gasket during installation, the straight-through type reducing housing of inner liner abrasive resistant rubber, reduced resistance to motion, life cycle is 10～15 times of common steel reducer, has greatly increased the life in application of equipment, reduce the replacing number of times of equipment, reduced the user cost of equipment.
Description of drawings
Fig. 1 is reducing line with rubber steel casing expander structural representation.
Among the figure: the 1st, inner sleeve, the 2nd, inner sleeve flange, the 3rd, clamping bolt, the 4th, gland, the 5th, outer sleeve flange, the 6th, seal ring, the 7th, back-up ring, the 8th, outer sleeve, the 9th, loose flange, the 10th, caging bolt.
Embodiment
The utility model reducing line with rubber steel casing expander is achieved in that below in conjunction with accompanying drawing makes specific description.See Fig. 1, the utility model reducing line with rubber steel casing expander, by: inner sleeve 1, inner sleeve flange 2, clamping bolt 3, gland 4, outer sleeve flange 5, seal ring 6, back-up ring 7, outer sleeve 8, loose flange 9 and caging bolt 10 form, consisted of the straight-through type reducing housing of steel structure inner liner abrasive resistant rubber material by inner sleeve 1 and outer sleeve 8, in inner sleeve 1 and outer sleeve 8, be provided with seal ring 6, inner sleeve 1 and inner sleeve flange 2 are structure as a whole, and are lined with the abrasive rubber material in inner sleeve 1 inside.
Loose flange 9 can rotate freely according to the position in pipeline upper flange hole in installation, favourable solution install in piping flange not to the hole problem.
One end of the utility model reducing line with rubber steel casing expander is that the import the other end is outlet, be installed on the pipeline of slag stock pump outlet, the import of reducing line with rubber steel casing expander is connected with the outlet of slag stock pump, when the slag stock pump normally moved, reducing line with rubber steel casing expander can be according to the temperature free-extension of medium; And has a reduction noise performance.Life cycle is 10～15 times of common steel reducer, has greatly increased the life in application of equipment.At inner sleeve and outer sleeve inner liner abrasive resistant rubber, have characteristics wear-resisting, corrosion-resistant, that life cycle is long, reduced the replacing number of times of valve, alleviated workman's labor intensity, reduced the user cost of equipment.
