Embodiment Construction

[0027] 1. Manufacture circular (or square or other shapes) foil plate materials by mechanical processing, laser processing, electrical processing, etc.;

[0028] 2. Clean the surface of the material through a variety of surface treatments to remove all dust, presence or absence of dirt on the surface of the material;

[0029] 3. Accurate control of the boundary line between the welding area and the non-welding area of ​​the diffusion-welded multi-layer structure membrane box is realized by engraving after coating the surface protective glue;

[0030] 4. Stop welding for parts that do not require diffusion welding;

[0031] 5. For the parts that need to be welded by diffusion welding, the surface modification treatment of materials is carried out by means of ion implantation, chemical deposition, electroplating, chemical plating, etc. (some grades of materials may not be carried out);

[0032] 6. Assemble the materials according to a certain assembly relationship and assembly ...

Abstract

The invention is a diffusion welding multilayer structure diaphragm capsule, belonging to the field of diaphragm capsule manufacturing. By adopting the methods of diffusion welding, machining and shaping, the manufacturing of diaphragm capsule in the invention can be realized. The main procedures include thin wall blank preparation, surface cleaning, surface modified treatment, welding-stopping treatment, diffusion welding, machining, shaping and the like. Compared with the multilayer structure diaphragm capsule manufactured by other methods, the multilayer structure diaphragm capsule manufactured by the invention has the advantages of fine fatigue property (above 1 million times), strong pressurization performance, adjustable rigidity, high compression ratio (higher than 80%), capability of micromation of inner holes, high precision of geometric dimensions, strong destabilization resistance, precise and controllable weldingline profile, adjustable width of weldingline and the like. By using the invention, the diaphragm capsule in the shape of circle, square and other shapes can be manufactured, and can serve as a compensation element of displacement and angle in hydraulic, barometric, transferring pipeline installation, an elastic compensation element and a pore damping element as well as a measuring element for a manometer and an altimeter; besides, the diaphragm capsule can be also used as a heat transferring finned tube for air conditioning, refrigeration and other devices as well as a metal capsule of separating gas or liquid for an accumulator and a storage box. The invention can provide multilayer structure diaphragm capsule products with fine performance for related industries.

Description

1. Technical field [0001] The invention can be applied to displacement compensation and angle compensation for installation of hydraulic pressure, air pressure, and conveying pipelines, can be used as an elastic compensation element for valve products, can be used as a pore damping element for valve products, and can be used for measurement of pressure gauges and altimeters A component that can be used as a pressure accumulator, a metal bladder that isolates gases or liquids in a tank. 2. Background technology [0002] Compared with ordinary bellows, the multi-layer structure capsule has the characteristics of low stiffness under the same compressive strength and high pressure bearing capacity under the same stiffness, which provides a new design for the elastic components of aviation and aerospace valve products. Design ideas. [0003] At present, domestic and international multi-layer structure capsules are rarely used. The main reason is that the current manufacturing me...
