Abstract
A kind of coating die of flange sealing surface, including: a mould closed with flange sealing surface matching form, the several link bolt hole being arranged on disc for die, molding bolt hole and sealing water wave line profile.It is provided with ribs in the middle part of the disk of described mould；Mould is provided with suspension centre, alignment pin, handle.This utility model can not only carry out pressure coating protection to pressure bearing and seal face, solves long-acting anti-corrosion protection problem；And, also eliminate due to mould poorly sealed problem produced by produced slight deformation during assembling.
Description
Technical field
This utility model relates to mould, particularly relates to a kind of on-the-spot for the sealing surface in Big Diameter Flange anticorrosive construction
The coating die of the flange sealing surface of coating.
Background technology
At present, inside the profit processing equipments such as ocean engineering pressure vessel and equipment, usually contain corrosive acid, alkali,
The media such as salt, in the finishing system of these pressure vessel and equipments, its contact especially needed vigilant crevice corrosion of sealing surface and electricity
Thermogalvanic corrision.
Existing coating process is: at pipe connecting flange or the flange sealing surface of manhole flange sealing surface, especially major diameter
Water wave line can be caused to hide, and coating is hit in fastening bolt and assembling and extrudes also can be damaged, it is impossible to forms pressure-bearing profile.
Therefore, the flange contact sealing surface in profit processing equipment and transport pipeline is caused to become by corroding one of the most serious position.
Due to the corrosion in advance of flange contact sealing surface, not only break up the complete of profit processing equipment and transport pipeline entirety corrosion protection system
Whole property, cause serious hindrance properly functioning to profit processing equipment and transport pipeline, and destructive accident may be led to.And due to
Pressure vessel and equipment spraying process feature is that all prefabricated work completes just to allow to carry out corrosion-inhibiting coating construction after the water pressure test,
Therefore, anticorrosive construction must possess on-the-spot operability as last operation.
Utility model content
Main purpose of the present utility model is the disadvantages mentioned above overcoming prior art to exist, and provides a kind of flange seal
The coating die in face, it can not only carry out pressure coating protection, solve long-acting anti-corrosion protection and ask pressure bearing and seal face
Topic；And, also eliminate due to mould poorly sealed problem produced by produced slight deformation during assembling.
The purpose of this utility model is realized by techniques below scheme:
A kind of coating die of flange sealing surface, it is characterised in that: including: a mould closed with flange sealing surface matching form
Tool, the several link bolt hole being arranged on disc for die, molding bolt hole and sealing water wave line profile.
It is provided with ribs in the middle part of the disk of described mould；Mould is provided with suspension centre, alignment pin, handle.
The beneficial effects of the utility model: this utility model is owing to using technique scheme, and it can not only be to pressure-bearing
Sealing surface carries out pressure coating protection, solves long-acting anti-corrosion protection problem；And, also eliminate owing to mould is in assembling
Poorly sealed problem produced by slight deformation produced by during.

Detailed description of the invention
As shown in Fig. 1 Fig. 4, this utility model includes: the mould 8 that matches mutually with flange 9 sealing surface shape, be arranged on
Several link bolt hole 2, molding bolt hole 3 and sealing water wave line profile 5 on mould 8 disk, wherein, mould 8 is provided with and hangs
Point 1, alignment pin 6, handle 7；Ribs 4 it is provided with in the middle part of the disk of mould 8.
During use, the sealing water wave line profile 5 on mould 8, connection fastening bolt 11, the external coating of molding bolt 10
Releasing agent；The sealing surface of flange 9 is carried out sandblasting, at die sealing water wave line profile 5, flange 9 sealing surface surface brush coating,
Coating is scraped smooth；Mould 8 of the present utility model is arranged on flange 9 seals by molding bolt 10, connection fastening bolt 11
On face.When, after curing of coatings, being screwed into bolt 10 molding in molding bolt hole 3, now, flange 9 sealing surface surface i.e. forms water
Stricture of vagina shape seal coating 12.
The above, be only preferred embodiment of the present utility model, not this utility model is made any in form
Restriction, every according to technical spirit of the present utility model, above example is made any simple modification, equivalent variations with
Modify, all still fall within the range of technical solutions of the utility model.
