Abstract
The utility model discloses a non-metal expansion joint, which belongs to an expansion-compensation device for pipelines. The utility model comprises a hollow concave shell 1 and a hollow convex shell 2, wherein the inner walls of the shells are fixed with pouring material fixing forks 3, a stopping opening 4 between a concave and a convex parts of the shells is provided with a telescopic high temperature material layer 5, and the shells are centrifugally cast with high temperature material layers 6. The utility model has the advantages of good tightness and long service life, and the utility model can be used in the pipelines of various generating combustion engine flues, boiler flues and high temperature zone corrosive medium and other occasions in fire electricity, metallurgy, machine and other industries.
Description
The utility model relates to a kind of non-metal expansion joint, belongs to pipeline expansion compensation device.
Industrial, when carrying high temperature corrosion gas, for example carry 1100～1200 ℃ SO
2, SO
3During gas, owing to temperature height, gas are corrosive again, therefore be difficult to find suitable metal to do expansion joint, this adopts non-metal expansion joint often.The shell portion of a kind of expansion joint of the prior art is by fire-resistant brick system, and hermetic unit is made by glass fibre.This expansion joint often comes off refractory brick owing to the system of building is firm, and easy fracture causes the gas of seal failure, conveying to leak because glass fibre is very crisp again, and the life-span is short, fabricating cost is bigger.
The purpose of this utility model is to provide a kind of non-metal expansion joint of corrosion-resistant, high temperature resistant, good seal performance.
The purpose of this utility model is achieved in that
A kind of non-metal expansion joint, comprise hollow spill housing and hollow convex housing, being fixed with the pouring material fixation fork on the inner walls, is scalable exotic material layer in the seam between housing " recessed ", " protruding " position, and centrifugal pressure casting has the exotic material layer in the housing.
The outer wall of hollow spill housing and hollow convex housing is fixed with a frame respectively, is the thermal insulating filling layer in the cavity that two frames form, and the thermal insulating filling layer is outward a covering.
The inwall of the cavity that forms in frame is placed with a refractory steel silk screen.
The utility model has following advantage than prior art: (1) good seal performance, can be effectively heat insulation and isolate Korrosionsmedium, and prolonged the working life of housing and covering, thereby the life-span of whole expansion joint is long; (2) absorption three direction displacement amount is big, and axial dimension is little.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the sectional view of the utility model expansion joint.
Fig. 2 is the A-A view of Fig. 1.
A kind of non-metal expansion joint, comprise hollow spill housing 1 and hollow convex housing 2, be fixed with pouring material fixation fork 3 on the inner walls, axially dock at " recessed " of hollow spill housing 1 and hollow convex housing 2, " protruding " position, in the seam 4 between " recessed ", " protruding " position is scalable exotic material layer 5, and centrifugal pressure casting has exotic material layer 6 in the housing.The outer wall of housing is fixed with a frame 7 respectively, and putting in the cavity that a refractory steel silk screen 10, two frames form at the inwall of the cavity that frame forms is thermal insulating filling layer 8, and the thermal insulating filling layer is outward a covering 9.Be connected with pipeline by adpting flange 11 during use.Because the utility model expansion joint is symmetry axially, so Fig. 1 and Fig. 2 have only drawn half.
Claims (3)
1, a kind of non-metal expansion joint, it is characterized in that: this expansion joint comprises hollow spill housing (1) and hollow convex housing (2), be fixed with pouring material fixation fork (3) on the inner walls, in the seam (4) between housing " recessed ", " protruding " position is scalable exotic material layer (5), and centrifugal pressure casting has exotic material layer (6) in the housing.
2, expansion joint according to claim 1 is characterized in that the outer wall of hollow spill housing and hollow convex housing is fixed with a frame (7) respectively, is thermal insulating filling layer (8) in the cavity that two frames form, and the thermal insulating filling layer is outward a covering (9).
3, expansion joint according to claim 2 is characterized in that: the inwall of the cavity that forms in frame is placed with a refractory steel silk screen (10).
