Abstract
An anti-wear bushing comprises a bushing packing (1) with a pipe socket (2) at one end. The anti-wear bushing is characterized in that the pipe socket has a cycle of rotating edge inward.
Description
Technical field
The utility model belongs to a kind of boiler preheating organ pipe and smoke pipe sleeve pipe, is specifically related to a kind of Antiwear casing.
Background technology
The smoke pipe porch of Boiler smoke tube and preheater tube is because of the high-temperature gas that contains sulfur dioxide of preheater tube and smoke pipe porch and particle shape material corrode preheater tube and smoke pipe porch and rub badly damaged preheater tube and smoke pipe.Various boilers of Xiao Shouing in the market, at all supporting irony sleeve pipe that is provided with of its preheater tube and smoke pipe porch, because sleeve pipe is to insert preheater tube and smoke pipe porch inwall, and existing sleeve pipe is to adopt ferrous material to make, casing wall itself is very thick, when making the smoke evacuation of boiler preheating organ pipe and smoke pipe in use and crossing gas resistance big, have some setbacks, strengthened frictional force, therefore the sleeve pipe weak point of this structure to sleeve pipe: the one, not wear-resisting; The 2nd, non-refractory; The 3rd, Corrosion Protection is poor; Four are to use the life-span short; The 5th, the cost height; The 6th, influenced the burning quality of boiler.
The utility model content
The purpose of this utility model is the deficiency that overcomes existing sleeve technology, provide a kind of reasonable in design, simple in structure, antifriction, high temperature resistant, decay resistance strong, long service life, cost is low, the boiler combustion quality is high novel Antiwear casing.
The utility model is achieved by the following technical solution: the utility model comprises sleeve body, and sleeve body one end is provided with horn mouth, it is characterized in that described horn mouth edge inwardly is provided with a circle and changes the limit, and described sleeve body is to make with stainless steel material.
Owing to adopted technique scheme, compare with existing sleeve technology, have following beneficial effect: the one, inwardly being provided with a circle at the horn mouth edge changes the limit, has in fact increased the thickness at sleeve pipe horn mouth place, has promptly increased the abrasionproof performance of sleeve pipe; The 2nd, sleeve pipe adopts stainless steel material to make, and casing wall is thin, the resistance when having reduced the smoke evacuation of boiler preheating organ pipe and smoke pipe and having crossed gas, smoke evacuation and gas smooth and easy, improved the boiler combustion quality; The 3rd, also reduced the frictional force of smoke and gas simultaneously to sleeve pipe, long service life is at least more than 1 times of common irony sleeve pipe the service life of this Antiwear casing; Four are to use cost low; The 5th, decay resistance is strong; The 6th, simple in structure, only needing inwardly changes the limit with the horn mouth edge.
Antiwear casing described in the utility model needing can be used for abrasionproof, anti-high temperature, etch-proof pipeline.
Description of drawings
Accompanying drawing is the utility model structural representation
In the drawings: 1, sleeve body 2, horn mouth 3, commentaries on classics limit
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments:
As shown in the figure, the utility model comprises sleeve body 1, and sleeve body 1 one ends are provided with horn mouth 2, it is characterized in that described horn mouth 2 edges inwardly are provided with a circle and change limit 3, and described sleeve body 1 is to make with stainless steel material.
Claims (2)
