Abstract
The invention discloses a high temperature expansion joint. The expansion joint comprises two end pipes and corrugated pipes connected between the two end pipes, wherein at least two anchoring parts are arranged on the inner walls of the end pipes and the corrugated pipes; the anchoring parts comprise Y-shaped anchoring part bodies; coatings which can burn at high temperature are coated at the two front ends of the Y-shaped anchoring part bodies to form coating layers; and the length of the coating layers is 2mm. The expansion joint has the following beneficial effects that at least two anchoring parts are arranged on the inner walls of the end pipes and the corrugated pipes; anchoring part caps are not adopted, but instead, the coatings which can burn at a high temperature are coated at the two front ends of the Y-shaped anchoring part bodies to form coating layers; and the length of the coating layers is about 2mm, the coatings burn at a high temperature and gaps are reserved, thus ensuring the castables not to be easily damaged.
Description
Technical field
The present invention relates to expansion joint, relate in particular to a kind of high temperature expansion joint.
Background technique
The high temperature expansion joint that arrives commonly used in industry such as metallurgy, cement, thermoelectricity.The effect of high temperature expansion joint mainly is for fear of high-temperature gas and high-temperature-hot-water conveyance conduit snapping, being out of shape or fracture in frequent process of expansion and contraction.Expansion joint has multiple, for example bellows expansion joint.Standing in the expansion joint have anchoring piece, anchoring piece to be provided with the anchoring piece cap, is beneficial to water the location and the setting of firmware.But anchoring piece closely contacts with pouring material easily, causes pouring material to be damaged.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to above-mentioned existing technology, and a kind of high temperature expansion joint that is not easy to cause the casting material damage is provided.
For solving the problems of the technologies described above, the technological scheme that the present invention takes is: a kind of high temperature expansion joint, and comprise two end pipes and be connected two bellowss between the end pipe, it is characterized in that: on end inner tube wall and bellows inwall, be equipped with at least two anchoring pieces; Said anchoring piece comprises Y shape anchoring piece body, and the coating that when two front ends of said Y shape anchoring piece body scribble at high temperature, can burn forms coating layer.
As the further improved technological scheme of the present invention, said coating layer length is 2mm.
As the further improved technological scheme of the present invention, also comprise being connected two position-limited levers between the end pipe.
The present invention is provided with at least two anchoring pieces on end inner tube wall and bellows inwall; Do not adopt the anchoring piece cap, but the coating that when two front ends of Y shape anchoring piece body scribble at high temperature, can burn forms coating layer.Coating layer is about 2mm, and coating burns when high temperature, and leaving gap makes pouring material not fragile.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an anchoring piece structural representation of the present invention.
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
Embodiment
[0014] referring to Fig. 1 and Fig. 2, the Ben Gaowen expansion joint comprises two end pipes 4 and is connected two bellowss 5 between the end pipe 4, on end pipe 4 inwalls and bellows 5 inwalls, is equipped with at least two anchoring pieces; Said anchoring piece comprises Y shape anchoring piece body 1, and the coating that when two front ends 2 of said Y shape anchoring piece body 1 scribble at high temperature, can burn forms coating layer 3.Said coating layer 3 length are 2mm.Also comprise and be connected two position-limited levers 6 between the end pipe 4
Evenly distributed between a plurality of anchoring pieces, can an angle be arranged compartment relatively between each anchoring piece.In the present embodiment 90 degree.The present invention does not adopt the anchoring piece cap, but the coating that when two front ends 2 of Y shape anchoring piece body 1 scribble at high temperature, can burn forms coating layer 3, and coating layer 3 is about 2mm.Coating adopts the existing material that can when high temperature, burn, and he will leaving gap after coating burns during at high temperature like this, makes pouring material not fragile.
Claims (3)
1. a high temperature expansion joint comprises two end pipes (4) and is connected the bellows (5) between two end pipes (4), it is characterized in that: on end pipe (4) inwall and bellows (5) inwall, be equipped with at least two anchoring pieces; Said anchoring piece comprises Y shape anchoring piece body (1), and the coating that when two front ends (2) of said Y shape anchoring piece body (1) scribble at high temperature, can burn forms coating layer (3).
2. the special-purpose anchoring piece of high temperature expansion joint according to claim 2, it is characterized in that: said coating layer (3) length is 2mm.
