Abstract
A kind of rubber lined pipe and end face of flange linkage structure, comprise interconnective metal tube and flange, the seal face place of described flange is provided with rubber bushing, and rubber bushing is annular; Metal pipe internal surface and rubber bushing are outside coated by rubber bushing.Advantage of the present utility model is as follows: 1, metallic conduit is connected with knuckle with end face of flange, to reduce slurries resistance, reduces wearing and tearing; 2, end face of flange place arranges rubber bushing, the rubber bushing of metal tube is coated on outside inner wall of metal tube and rubber bushing, so not only ensure that end face of flange place line with rubber thickness, improves sealing effect, after making again metal tube rubber bushing rout up, buffer layer has been arranged at bottom, can not press against wound and burst apart.The utility model sealing effect is good, eliminates rubber-lined pipe flange connections seepage easy to wear, poorly sealed drawback.
Description
Technical field
The utility model relates to a kind of pipeline configuration, particularly a kind of for carrying rubber lined pipe and the end face of flange linkage structure of Korrosionsmedium.
Background technique
The big-and-middle-sized firepower electrical plant of current domestic majority all have employed limestone-gypsum sulfur removal technology that smoke desulfurization efficiency is higher, Technical comparing is ripe.The slurries pipeline system media of wet desulphurization is the mixture of water and solid particulate matter, and it should have all characteristics of common fluid pipeline, has easy to wear, easy blocking, the own characteristic such as perishable again.The anticorrosion antiwear of metallic conduit conveying slurries to depend in pipe fitting rubber lining lining, and rubber lined pipe is subject to slurry erosion and wearing and tearing and seepage, particularly pipeline and flange connections are the weak links that seepage easily occurs.Trace it to its cause, the structure of traditional inner-walls of duct and end face of flange joint to be used for inner-walls of duct line with rubber and to reserve the rubber bushing of certain length, stretched out to rout up by rubber bushing to be directly affixed on end face of flange from inner.This structure makes the rubber bushing of stretching form tension force, and line with rubber layer thickness reduces 1-2mm herein.In addition, clear up although carried out welding slag to the surface, joint of metal tube and end face of flange before line with rubber and polish process, being bordering on rectangular-shaped structure herein and very easily after the direct flange of rubber bushing, line with rubber layer being formed and press against wound, leave hidden leakage defect.In sum, the seepage of desulfurization rubber lined pipe and flange connections has become the difficult problem having a strong impact on slurries pipeline and normally run.
Model utility content
The purpose of this utility model is the drawback for prior art, provides a kind of and effectively keeps away metal tube and flange connections easy to leak and poorly sealed rubber lined pipe and end face of flange linkage structure.
Problem described in the utility model realizes with following technical proposals:
A kind of rubber lined pipe and end face of flange linkage structure, comprise interconnective metal tube and flange, the seal face place of described flange is provided with rubber bushing, and rubber bushing is annular; Metal pipe internal surface and rubber bushing are outside coated by rubber bushing.
Above-mentioned rubber lined pipe and end face of flange linkage structure, the welding part of described metal tube and flange seal end face is provided with knuckle, and the inner port edge of described rubber bushing extends and coated knuckle to knuckle.
Above-mentioned rubber lined pipe and end face of flange linkage structure, be connected by adhesive layer between rubber bushing and the seal face of flange, and described metal tube is connected by adhesive layer with between rubber bushing, is connected between rubber bushing with rubber bushing by adhesive layer.
Above-mentioned rubber lined pipe and end face of flange linkage structure, the thickness of described rubber bushing is 2 millimeters.
The utility model provides a kind of rubber lined pipe and end face of flange linkage structure for solution rubber lined pipe metal tube and flange connections easy to leak problem.The metal tube of described linkage structure is connected with knuckle with end face of flange, can reduce slurries resistance, reduces wearing and tearing; End face of flange place arranges rubber bushing, the rubber bushing of metal tube is coated on outside inner wall of metal tube and rubber bushing, so not only ensure that end face of flange place line with rubber thickness, improves sealing effect, after making again metal tube rubber bushing rout up, buffer layer has been arranged at bottom, can not press against wound and burst apart.Test shows: adopt the utility model significantly can reduce the slurries transporting resistance of metallic conduit and flange connections, ensure that the line with rubber thickness at end face of flange flange place, sealing effect is good, eliminates rubber-lined pipe flange connections seepage easy to wear, poorly sealed drawback.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged view at Fig. 1 A place.
In figure, each list of reference numerals is: 1, metal tube, 2, rubber bushing, 3, flange, 4, knuckle, 5, adhesive layer, 6, rubber bushing.
Embodiment
Referring to Fig. 1, Fig. 2, rubber lined pipe described in the utility model and end face of flange linkage structure comprise metal tube 1 and flange 3, and metal tube and flange are through being welded to connect.The welding part of metal tube and flange seal end face joint is trimmed to smooth knuckle 4, and this knuckle significantly can reduce this place's slurries transporting resistance, and prevents from pressing against and hinder rubber bushing.The utility model is provided with rubber bushing 2 at the seal face place of flange, rubber bushing is annular, rubber bushing is bonded in the seal face of flange through adhesive layer, and the inner port edge place of rubber bushing extends to knuckle place, be coatedly bonded in outside knuckle.Rubber bushing 2 through adhesive layer by metal pipe internal surface and rubber bushing outer surface coated.Said structure, rubber bushing 6 one aspect set up ensure that the thickness of end face of flange place rubber layer, improves sealability; Rubber bushing is by the coating function to welding part on the other hand, and rubber bushing is not pressed against wound and burst apart to have had buffer layer fully to ensure bottom after making rubber bushing rout up.
The utility model make time first by metal tube and flange welding integral; The seal face weld reconditioning of metal tube and flange is gone out knuckle; Metal pipe internal wall and end face of flange are carried out sand blast and carries out surface clean degreasing; At inner wall of metal tube and end face of flange coated with adhesive layer; Rubber bushing is bonded in inner wall of metal tube, and rubber bushing end reserves the surplus in order to flange; At end face of flange sticking rubber liner, rubber bushing stretches to knuckle position and bonds; Coated with adhesive layer on rubber bushing outer surface; Rubber bushing is reserved position to stretch and rout up and be pasted on rubber bushing outer surface, roll real after finished edge profile.Rubber bushing drawn is positioned at the position of end face of flange thickness after routing up is less than the thickness being positioned at metal tube position, but owing to being provided with rubber bushing, so the integral thickness of end face of flange place rubber layer is greater than metal tube position.In the illustrated embodiment, the part thickness that rubber bushing is positioned at metal tube is 5 millimeters, and the part thickness that rubber bushing is positioned at end face of flange place is 4 millimeters, and rubber bushing is 2 millimeters.
