Technical field
The utility model relates to corrosion-proof technology for pipeline fields, especially a kind of to give flanged fitting Lining device.
Background technique
The pipe fitting that the present invention is previously mentioned is indispensable component in pipe conveying procedure, and effect is to change quilt in pipeline
The medium conveying direction of conveying or to shunt, control the effects of flow, pipe fitting can be directly mounted on pipeline (welding) or band
Flange installation is formed flanged fitting after upper flange is welded in the inlet and outlet end of pipe fitting and by bolt and main pipeline
On flange be attached.Currently, in order to improve the reparation of the service life of pipeline and old pipeline, technical staff has been invented
Lined technology, covers inner wall of the pipe by the lining of anti-corrosion, wear-resistant material, the medium conveyed is not inside conveyance conduit
Pipeline is directly contacted, so that pipeline is not corroded and is worn, to improve the service life of pipeline, compares the pipeline being widely used
Inside lining composite material Manifold technology is exactly one of.And as itself anti-of pipe fitting indispensable in pipeline
Mill, corrosion-resistant and in consideration range, but pipe fitting can not be also usually coated while lining conduit, can only be considered individually
It just needs to solve with flanged fitting to this is attached with lining pipe conduit again after pipe fitting lining.It is existing at present to give flanged fitting
Lined technology is the mode of 1. rotational moulding, i.e., by molding powder or granule filling to flanged fitting, pipe heating is made plastics
Powder or particles fuse simultaneously form one layer of uniform plastics lining by the pipe fitting inner wall that is rotated in of equipment.2. being to utilize spraying technology
Fusion of metal powder is formed into a non-ferrous metal protective layer in pipe fitting inner wall by thermal-flame.3. being in pipe fitting inner wall by people
Work welds non-ferrous metal board, patch potsherd etc..The mode of these liners has different degrees of deficiency, and rotomoulding apparatus is huge, produces
Product uneven thickness, it is impossible to be used in pressure piping provides that it can only be in 2.5Mpa or less using pressure by HG/T20538-2016.Spray
It is expensive to apply technical equipment complexity, material price.Human weld's difficulty is big, there is blind angle, cannot entirely reach all standing.It is artificial to paste
The processing of potsherd technical requirements pipe fitting inner wall is strictly not easy to reach requirement and manual operation less can guarantee quality, and potsherd is easily de-
It falls and liner is caused to fail.It is guaranteed and can adapt to the pipe fitting of construction site that a kind of quality simple to operation is provided in summary
Lining technique has been that industry institute is necessary.
Summary of the invention
The object of the present invention is to provide a kind of applicable a variety of composite lining materials, overcome the shortcomings of the prior art,
It can use at the construction field (site) and simple and easy preparation facilities, flanged fitting is enable to be formed as liner pipe reliably
Continuous anticorrosion antiwear layer, improves the service life of integrated piping.
The purpose of this utility model is realized by following technological means: flanged fitting welds steel flange by normal bend
It forms, flanged fitting is cased with liner mould group, and silk plug, the first connection bolt, seal taper sleeve, positioning company are successively arranged on liner mould
Plate, interior lining core, pressurization injecting device connect the discharge port that gland center is provided with by high-pressure rubber pipe, and pressurization injecting device is equipped with feed bin,
Piston is installed in feed bin, feed bin top is sealed by gland, and feed bin external process has ring flange, and connecting rod is fixed by nut
On ring flange, the connecting rod other end is threadedly secured on pedestal, and pedestal is bolted feed bin by the second connection, in pedestal
Hydraulic top is laid between feed bin, positioning connecting plate will position the steel flange spiral shell on connecting plate and flanged fitting by bolt and nut
Hole is fixed, and forms liner layer.Liner layer is made of anti-corrosion, wear-resistant material, is coated on normal bend inner surface and steel method
Blue connecting end surface, is continuous clad；Interior lining core is made of any flexible material, is similar to the hollow part of any pipe fitting,
It can also be solid, outer dimension and pipe fitting and liner layer thickness are interrelated；Hydraulic top can be spiral as pressurization feeding
Top or hydraulic top.
The utility model is the utility model has the advantages that reasonable in design practical, and the Lining device of the flanged fitting is in flanged fitting
The miniaturization site operation of lining bring it is feasible, by the site operation of the device, after the completion of pipeline is served as a contrast and filled, using the device
Liner directly is carried out to flanged fitting at the scene, the inside of pipe fitting and pipeline is made all to form the lining of an entirety, construction is existing
Field also need not be worried prefabricated in advance or to wait prefabricated pipe fitting problem again, utilizes flange internal lining pipe made by the utility model
Part is bigger than the liner layer compactness of the flanged fitting by other modes liner, and quality is high, thus bearing capacity is strong, can be in height
Installed on pressure pipeline, but can direct manufacturing flange inner liner pipe fitting at the construction field (site), thus the utility model makes flange liner
Pipe fitting application obtains further expansion, has significant economic benefit and social benefit.
