Abstract
The utility model discloses a high-pressure two-way rupture disk of a monolithic structure and relates to the technical field of rupture disks. The high-pressure two-way rupture disk of the monolithic structure comprises a diaphragm, wherein an arc-shaped protrusion is formed in the middle of the diaphragm, a cross-shaped weakening groove is formed in the middle of the concave face of the arc-shaped protrusion, a weakening groove is formed in the periphery of the diaphragm, and the weakening groove is formed in the outer side of the arc-shaped protrusion. The high-pressure two-way rupture disk of the monolithic structure is novel in structure and is a two-way rupture disk, two-way discharge can be achieved, a container is prevented from being damaged under the condition of vacuum, overpressure and positive and negative pressure difference, the high-pressure two-way rupture disk of the monolithic structure can be used under the condition that bursting pressure is high, and the requirements of users are met.
Description
Technical field
The utility model relates to a kind of high-voltage bidirectional rupture disk of monolithic structure, 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 the pressure difference of rupture disk both sides reaches predetermined value, rupture disk moves (break or come off) at once, relieving pressure, the safety of guarantee 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: four kinds of positive arch rupture disks, antiarch shape rupture disk, plate shaped rupture disk, graphite rupture disk.
Using at present maximum is unidirectional rupture disk, and in vacuum, superpressure with have under the operating mode of positive and negative pressure, unidirectional rupture disk cannot satisfy 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 high-voltage bidirectional rupture disk of monolithic structure.
The high-voltage bidirectional rupture disk of monolithic structure of the present utility model, it comprises diaphragm, and the middle part of diaphragm forms arch projection, and the concave surface middle part of arch projection is provided with cross and weakens groove, and the periphery of diaphragm is provided with and weakens groove, and weakens groove and be arranged on the outside of arch projection.
The beneficial effects of the utility model are: its novel structure, for two-way rupture disk, can realize two-way releasing, the in the situation that of preventing in vacuum, superpressure and have positive/negative pressure poor, container destroys, can in the situation that bursting pressure is higher, use, meet consumers' demand.
Brief description of the drawings
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is plan view of the present utility model.
In figure: 1-diaphragm; 2-arch projection; 3-cross weakens groove; 4-weakens groove.
Embodiment
For making the purpose of this utility model, technological scheme and advantage more cheer and bright, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these descriptions are exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, omitted the description to known features and technology, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1-2, this embodiment is by the following technical solutions: it comprises diaphragm 1, and the middle part of diaphragm 1 forms arch projection 2, and the concave surface middle part of arch projection 2 is provided with cross and weakens groove 3, the periphery of diaphragm 1 is provided with and weakens groove 4, and weakens groove 4 and be arranged on the outside of arch projection 2.
This embodiment is single-layer arch diaphragm, and its processing process is: neck material, blanking, base, moulding, cross cutting, hoop cutting, stress-relieving by beat treatment.
This embodiment is the convex surface of arch projection 2 high pressure side in pressure system in use, and when action, because compression unstability is broken, arch projection 2 concave surfaces are carved with cross and weaken groove 3, weaken the strength of materials, after unstability upset, rupture disk is torn along cutting place, relieving pressure, and rupture disk moulding bore periphery is provided with and weakens groove 4 simultaneously, in the time that the recessed side pressure of rupture disk is too high, rupture disk is subject to tension fracture, comes off weakening groove 4 places, and relieving pressure, thereby can two-way shot, regulate positive/negative pressure poor.
More than show and described 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; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of 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.
