Description
Technical field
The invention belongs to haloflex preparation fields, and in particular to a kind of haloflex reaction kettle enamel repairing side
Method and component.
Background technology
Repairing after existing haloflex reaction kettle enamel damage, the damage of small area are attacked in kettle internal drilling
Silk, repair piece is fastened on corrosion-resistant bolt on autoclave body.The failure area of larger area is repaired, and the feelings perforated especially occurs
Under condition, then using the hole penetrated, the method tensed from outside with bolt.Need experienced maintenance personal, running check fastening.
The maintenance personal to lack experience, it is easy to which spot failure is magnified.In general, the short reason of repairing point service life is exactly to use
Gasket is tetrafluoro material, needs frequent follow-up investigations and firm.It frequently occurs repairing point to be difficult to check, is not to check after repairing
Frequently, cause to influence to produce;Otherwise it just checks not in place, is difficult to find when leaking, the enamel for causing whole value expensive
The heavy losses that reaction kettle is scrapped.
Invention content
The present invention provides a kind of haloflex reaction kettle enamel method for repairing and mending and component, this hair to solve Problems Existing
The bright reaction kettle that substantially reduces is because repairing point failure again, and causing problem to be extended to can not retrieve, up to what reaction kettle was scrapped asks
Topic.After present invention repairing is finished and come into operation, hand inspection is not needed.
The technical solution adopted by the present invention to solve the technical problems is:
On the one hand the present invention provides a kind of haloflex reaction kettle enamel method for repairing and mending, includes the following steps:
1, the specification of anti-corrosion repairing plate, teflon gasket, turnbuckle, butterfly spring is selected;
2,1. the central punch of the failure area in reaction kettle body internal jacket, penetrates reaction kettle body external jacket;
3, on reaction kettle body external jacket, centre bore 1. centered on, trepanning is 2.;
It 4, will be with the hole 2. matched chuck distance sleeve of size and the weldering of reaction kettle body internal jacket outer wall and reaction kettle body external jacket
It connects, keeps pressing container pressure grade, suppress and do not leak;
5, turnbuckle is threadedly secured on anti-corrosion repairing plate in the upper teflon gasket of turnbuckle other end set, and from
Reaction kettle body inner wall is pierced by, and disk spring is set on turnbuckle, screws on locking nut in turnbuckle, is twisted with torque wrench
Tightly, you can come into operation.
Preferably, the format diameter of the corrosion-resistant plate is bigger 90~110mm than failure area diameter.Since the present invention is suitable
In production technology for internal pressure less than 0.8MPa, glassed steel reaction vessels internal pressure is less than 0.8MPa, in long-term life
Production use during can make damaged part generate a tension, the elastic force of glassed steel reaction vessels internal pressure combination butterfly spring with
Service life, the format diameter 90~110mm service lifes bigger than failure area diameter and cost of corrosion-resistant plate just can reach
Most preferably.
