Abstract
The utility model discloses a kind of small-bore combined type rupture disk, it relates to rupture disk technical field, and it comprises pressure ring and rupture disk; Rupture disk is arranged on the bottom of pressure ring, and the outer ledge of rupture disk is wrapped in the outside of pressure ring bottom, and the centre of rupture disk upwards forms arch projection.Its volume is little, easy for installation, and structure is simple and can not be formed and take out limit, and rupture disk pressure is accurate, practical.
Description
Technical field
The utility model relates to a kind of small-bore combined type rupture disk, belongs to rupture disk technical field.
Background technique
Rupture disk is the important safety of pressurized container, pipeline, and at the explosion temperature of regulation, when rupture disk pressure at both sides difference reaches predetermined value, rupture disk action at once (break or come off), relieving pressure, ensures the safety of people's life and national wealth.Rupture disk is widely used in the fields such as chemical industry, oil, metallurgy, nuclear power, aviation.Rupture disk is divided into by the difference of failure mode and material: positive arch rupture disk, antiarch shape rupture disk, plate shaped rupture disk, graphite rupture disk four kinds.The rupture disk by which kind of type is selected according to operating mode.Current existing rupture disk is substantially all be installed in supporting clamp holder according to latus rectum specification or be directly loaded in flange, and volume is large, and when client needs to be contained on bolt block or other little equipment, existing blasting piece device cannot meet the demands.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of small-bore combined type rupture disk.
Small-bore combined type rupture disk of the present utility model, it comprises pressure ring and rupture disk; Rupture disk is arranged on the bottom of pressure ring, and the outer ledge of rupture disk is wrapped in the outside of pressure ring bottom, and the centre of rupture disk upwards forms arch projection.
The beneficial effects of the utility model are: its volume is little, easy for installation, and structure is simple and can not be formed and take out limit, and rupture disk pressure is accurate, practical.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure: 1-pressure ring; 2-rupture disk; 3-arch is protruding.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly understand, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1, this embodiment by the following technical solutions: it comprises pressure ring 1 and rupture disk 2; Rupture disk 2 is arranged on the bottom of pressure ring 1, and the outer ledge of rupture disk 2 is wrapped in the outside of pressure ring 1 bottom, and the centre of rupture disk 2 upwards forms arch projection 3.
This embodiment belongs to right arch plain edition rupture disk, is mainly used in gas cylinder tack valve.
This embodiment processing technology comprises: neck material, blanking, base, bound edge, shaping, cleaning.First the material of bursting pressure determination rupture disk as required and the size of material thickness and pressure ring, be then placed on rupture disk in wrapping mold and carry out bound edge, be placed in shaping die after bound edge, and it is shaping that bursting pressure as required carries out pre-arch.Rupture disk is individual layer diaphragm, arch face wall thickness reduction during superpressure and tension fracture, causes rupture disk explosion, relieving pressure.
Embodiment:
Need model to be the rupture disk of LP7-5.8-A (represent model be right arch plain edition, bore of releasing is 7 ㎜, and design bursting pressure is 5.8MPa, and explosion temperature is normal temperature 22 DEG C, and sealing surface pattern is plane sealing), franchise is ± 5%.
Its manufacture method is: neck material, blanking, base, bound edge, shaping, cleaning.By design, select thickness to be that the Ni of 0.0508 ㎜ carries out shaping, select diameter phi 14mm, the aluminium pressure ring of thickness 3mm, briquetting pressure is carry out bursting test after 4.64MPa. completes, and data are 5.9MPa and 5.65MPa, franchise is respectively+1.72% and-2.59%, meets the demands.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
