Abstract
The utility model relates to an expansion joint with an anti-erosion structure, which comprises a corrugated pipe, a pipe connection, and a flow guiding sleeve, and is characterized in that a round bar for retaining the welded corner of the flow guiding sleeve is welded on the wall of the pipe connection in front of the welded corner of the fixed end of the flow guiding sleeve. The utility model has the advantages that the convex portion of the round bar can effectively prevent the deep erosion agents from flowing away the flow guiding sleeve, thereby increasing the service life of the expansion joint products.
Description
Technical field
The utility model belongs to a kind of pipeline compensator, particularly a kind of expansion joint with erosion control dendritic structure.
Background technique
There particularly often have expansion joint water conservancy diversion cover to be got by the medium erosion in the smoke wind pipe system in engineering in the past to be riddled with gaping wounds, even the situation that the water conservancy diversion cover is washed out.It is to reduce fluid flow resistance that inside is provided with the water conservancy diversion cover, but the situation of this ever-present ducted medium erosion water conservancy diversion cover and tube wall has had a strong impact on the life-span of product.
The model utility content
The purpose of this utility model provides a kind of expansion joint with erosion control dendritic structure, can prevent effectively that the strong medium of erosion from washing out the water conservancy diversion cover, prolongs the working life of expansion joint product.
The purpose of this utility model is achieved by the following technical solution: it comprises bellows, adapter and water conservancy diversion cover, it is characterized in that: weld one round steel on the adapter tube wall before water conservancy diversion cover fixed end leg, block the leg of water conservancy diversion cover with the convex portion of round steel.
The utility model has the advantages that: the convex portion of round steel can prevent effectively that the strong medium of erosion from washing out the water conservancy diversion cover, prolonged the working life of expansion joint product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
See Fig. 1, concrete structure is as follows: the two ends of bellows 4 connect respectively takes over 1, assembling water conservancy diversion cover 3 in bellows 4, and water conservancy diversion overlaps 3 one ends and is welded in the adapter 1, and the other end is a free end.One round steel 2 of welding on the adapter tube wall before water conservancy diversion overlaps 3 fixed end legs.
Claims (1)
1, a kind of expansion joint with erosion control dendritic structure, it comprises bellows, adapter and water conservancy diversion cover, it is characterized in that: the round steel of water conservancy diversion cover leg is blocked in welding together on the adapter tube wall before water conservancy diversion cover fixed end leg.
