Description

A kind of pressure test cylinder sealing surface anticorrosion treatment technology

Technical field

The present invention relates to a kind of pressure test cylinder sealing surface anticorrosion treatment technologies.

Background technique

Deep-sea simulated pressure test cylinder is mainly used to simulated deep-sea environment, the carry out voltage endurance capability survey to deep-sea test equipment Examination.Since interior media is the stronger seawater of corrosivity, salt corrosion and stress corrosion, pressure are generated to container in a high voltage state Power test cylinder flat cover needs often to open and close again, and frequency of usage is high, therefore the abrasion and hardness requirement to pressure test cylinder sealing surface are high. It cannot be met the requirements using conventional surface spraying technology, existing sealing corrosion method is without especially effective.Using anti- The materials such as austenitic stainless steel, the two phase stainless steel of rotten superior performance are as sealing surface, these right material higher costs, and material Strength character is not high, and welding difficulty is big.It adopts this method and is easy in the sealing surface use process of manufacture using stress corrosion, effect Fruit is bad.

Summary of the invention

It is an object of the invention to insufficient regarding to the issue above, it is desirable to provide one kind both can guarantee that flat cover and cylinder sealing connect Anti-corrosion, the sealing performance of contacting surface, and the abrasion of sealing contact surface is reduced, reduce the pressure test cylinder sealing surface anti-corrosion of process costs Treatment process.

Implementation method of the invention is a kind of pressure test cylinder sealing surface anticorrosion treatment technology, the specific steps are as follows:

1) sealing contact surface of cleaning pressure test cylinder cylinder and flat cover;

2) cylinder contact surface processes a concave station, then carries out built-up welding bottoming with pure nickel welding wire, then welded with Monel 400 Built-up welding corrosion-resistant alloy layer one carries out gas shield using the argon gas of purity 99.99% in weld deposit process, and the height of built-up welding should be stayed There is machining allowance;

3) flat cover contact surface surface processes a groove platform, then carries out built-up welding bottoming with pure nickel welding wire, then be with covering 400 welding rod built-up welding corrosion-resistant alloy layers two of that, process annular seal groove, clean seal slot seals annular seal groove on overlay cladding Firmly, resin glue is poured into seal groove;

4) annular seal groove pours resin glue and spends 24 hours, and after its solidification, annular seal groove is machined to technique requirement;

5) it is packed into sealing ring in the seal groove on flat cover, then flat cover is fitted into cylinder, form preserving and sealing Face.

The technique that the present invention is combined using welding anti-corrosion alloy and pouring resin glue, process both can guarantee simulation The antiseptic property of pressure test cylinder, and the abrasion of the less sealing contact surface of energy, while production cost is reduced, improve production effect Rate.

Detailed description of the invention

Fig. 1 is anti-corrosion layer structure schematic diagram of the present invention,

Fig. 2 is I magnified partial view in Fig. 1,

Fig. 3 is 1 contact face structure figure of flat cover.

Specific embodiment

The present invention is described in further detail below in conjunction with the accompanying drawings.

The specific steps of the present invention are as follows:

1) sealing contact surface of cleaning pressure test cylinder cylinder and flat cover;Clean diesel oil mechanical derusting, electrochemical deoiling and miscellaneous The method of matter.

2) 5 contact surface of cylinder processes a concave station, then carries out built-up welding bottoming with pure nickel welding wire, avoid corrosion resistant alloy with Ontology dilution is excessively high to influence anti-corrosion effect;400 welding rod built-up welding corrosion-resistant alloy layer 1 of monel metal is used again, is adopted in weld deposit process Gas shield is carried out with the argon gas of purity 99.99%, then the height of built-up welding should be machined out there are 1mm machining allowance.

3) 1 contact surface surface of flat cover processes a groove platform 7 (see Fig. 3), then carries out built-up welding bottoming with pure nickel welding wire, 400 welding rod built-up welding corrosion-resistant alloy layer 22 of Monel is used again, annular seal groove is processed on overlay cladding, and cleaning agent cleans seal groove The sundries such as surface derusting, greasy dirt and metallic dust are sealed annular seal groove with adhesive tape, and resin glue 3 is poured into seal groove;

It seals annular groove processing request roughness and is lower than Ra6.3, to increase the adhesive force of encapsulating resin glue.

4) annular seal groove pours resin glue and spends 24 hours, and after its solidification, annular seal groove is machined to technique requirement;

5) it is packed into sealing ring 6 in the seal groove on flat cover, then flat cover is fitted into cylinder 5, forms Fig. 1,2 institutes The preserving and sealing face shown.

The technique that the present invention is combined using welding anti-corrosion alloy and pouring resin glue, process both can guarantee simulation The antiseptic property of pressure test cylinder, and the abrasion of the less sealing contact surface of energy, while production cost is reduced, improve production effect Rate.
