Abstract
The utility model discloses a novel fiber expansion joint which comprises a left adapter tube, a U-shaped expansion joint and a right adapter tube, wherein the U-shaped expansion joint is fixedly connected between the left adapter tube and the right adapter tube; and a drain outlet is connected to the bottom of the U-shaped expansion joint. The novel fiber expansion joint is characterized in that an anticorrosion coating layer is coated at the bottom of the U-shaped expansion joint; and the area of the anticorrosion coating layer accounts for one third of the area of the U-shaped expansion joint. According to the novel fiber expansion joint, the service life of the U-shaped expansion joint in the environment with strong corrosivity is greatly prolonged, the cost is saved, the novel fiber expansion joint is applicable to the large-error horizontal mounting of pipelines, and the mounting technique is simple.
Description
Technical field
The utility model relates to a kind of expansion joint, particularly a kind of non-metal expansion joint.
Background technique
The filament expansion joint can provide bigger multidirectional compensation rate on less axial mounting distance; Can effectively eliminate simultaneously the installation integrating error of whole system, so extensively adopted, but the filament expansion joint often uses in the abominable flue of environment; Contain various acidic materials in the medium; Like sulfur dioxide, sulfur trioxide, sodium chloride etc., to the very corrosive of filament expansion joint, so the working life of filament expansion joint is often not long.
The model utility content
The utility model technical problem to be solved is the deficiency to above-mentioned existing technology, provides a kind of working life long filament expansion joint.
For solving the problems of the technologies described above; The technological scheme that the utility model adopted is: a kind of tencel expansion joint; Comprise left side adapter, U type expansion joint and right the adapter; U type expansion joint is fixedly connected between left side adapter and right the adapter, and U type expansion joint bottom is connected to discharge opening, it is characterized in that U type expansion joint bottom scribbles corrosion resistant coating.
As the further improved technological scheme of the utility model, the area of corrosion resistant coating accounts for 1/3 of said U type expansion joint area.
As the further improved technological scheme of the utility model, said corrosion resistant coating is a silicon sealant.
As the further improved technological scheme of the utility model, between a said U type expansion joint and a left side are taken over, and be connected with bolt between U type expansion joint and the right adapter, be lined with steel plate between U type expansion joint and the bolt and nut.
As the further improved technological scheme of the utility model, between a U type expansion joint and a left side are taken over, and be lined with sheet rubber between U type expansion joint and right the adapter.
As the further improved technological scheme of the utility model, said sheet rubber is an ethylene propylene diene rubber.
The utility model scribbles corrosion resistant coating in U type expansion joint bottom, can prolong the working life of U type expansion joint under the strong environment of corrosivity greatly, practices thrift cost, and applicable to the big pipe level installation of error, mounting process is simple.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
Embodiment
Embodiment 1
Referring to Fig. 1; This tencel expansion joint comprises that a left side takes over 1, U type expansion joint 2 and rightly take over 3, and U type expansion joint 2 is fixedly connected on a left side and takes over 1 and right the adapter between 3; U type expansion joint 2 bottoms are connected to discharge opening 4, it is characterized in that U type expansion joint 2 bottoms scribble corrosion resistant coating 5.
As optimized technical scheme, the area of corrosion resistant coating 5 accounts for 1/3 of said U type expansion joint area.Said corrosion resistant coating 5 is a silicon sealant.A said U type expansion joint 2 and a left side are taken between 1, and are connected with bolt between U type expansion joint 2 and the right adapter 3, are lined with steel plate 6 between U type expansion joint 2 and the bolt and nut.A U type expansion joint 2 and a left side are taken between 1, and are lined with sheet rubber 7 between U type expansion joint 2 and the right adapter 3.Said sheet rubber 7 is an ethylene propylene diene rubber.
This tencel expansion joint is applicable to the pipe level installation that error is big, installs simply, and its bottom scribbles corrosion resistant coating, can prolong filament expansion and save working life, the saving cost.
