Abstract
The utility model relates to a kind of single-layer metal film dust rupture disk, is made up of intensity film and gasket seal, and intensity film is metallic film, and three sides of this metallic film offer gap, and gasket seal is positioned at the both sides up and down of metallic film.Compared with prior art, the utility model structure is simple, light, and easily processes, and saves cost more than 60%; Transport, installation, replacing are conveniently, easy to use; Effectively can ensure the sealing of blasting piece device.
Description
Technical field
The utility model relates to a kind of rupture disk, especially relates to a kind of single-layer metal film dust rupture disk.
Background technique
Rupture disk safety installations has been widely used in the industries such as chemical industry, medicine, environmental protection, iron and steel, electric power now to be needed in the equipment of protection.Rupture disk safety installations is by the urgent pressure relief device of pressure differential, non-automatic cut out, mainly for the protection of pressurized container, pipeline or other closed system, makes it avoid causing because of excessive superpressure or vacuum destroying.
This class blasting piece device is mainly used in dust industry, and design for dusting apparatus equal pressure container overpressure relief, by double layer of metal, the dust rupture disk of prior art adds which floor plastic film forms usually, the process-cycle is longer, and material also compares waste.The dust also easy gap of cracking by metallic film is entered thus affects the performance of rupture disk.In order to address these problems, meet the needs of Market and Consumer, this is the problem that engineers and technicians need to solve.
Chinese patent CN201363555Y discloses panel dust rupture disk, this rupture disk comprises intensity film, sealing film, bracket, protective film, intensity film and bracket are provided with multiple cracking, sealing film is arranged between intensity film and bracket, protective film is arranged on the place of cracking of the upper and lower intensity film of sealing film and bracket, the sealing of rupture disk is ensured by sealing film, when adopting this technology, the tension pressure of the sealing film adopted itself must lower than the design pressure of rupture disk, when the design pressure of rupture disk is lower, market is difficult to buying ensures rupture disk normal unlatching to enough thin sealing film, therefore the rupture disk design pressure scope of this structure, by the restriction of sealing film.And because sealing film is very thin, if when protected equipment has a negative pressure, sealing film is easy to be destroyed, and therefore must arrange bracket to protect sealing film.The utility model relates to a kind of single-layer metal film dust rupture disk and is made up of intensity film and gasket seal, the place of cracking of intensity film fits tightly with gasket seal, ensure that the sealing of rupture disk, and structure is simple, compare with above-mentioned patent and eliminate sealing film, expand the design pressure scope of rupture disk, provide cost savings, enhance the competitiveness of product.
Model utility content
The purpose of this utility model is exactly provide a kind of structure simple, the convenient single-layer metal film dust rupture disk regulating bursting pressure to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of single-layer metal film dust rupture disk, is made up of intensity film and gasket seal,
Described intensity film is metallic film, and three sides of this metallic film offer gap to weaken intensity film strength, described gasket seal is positioned at the both sides up and down of metallic film.
Preferably, gasket seal is located at the outer of intensity film, and covers the gap that intensity film side is offered, and needs to ensure to seal between gasket seal and intensity film.
Preferably, the gasket seal that gasket seal is formed in one, or mutually bondd by strip pad and form.
Preferably, gap is provided with many, and be distributed on three sides of metallic film, the interval between each gap can be identical, also can be different.Controlled blasting pressure is carried out by regulating the gap size between each gap.
The outermost edges of described intensity film offers screw.
Compared with prior art, the utility model has the following advantages:
(1) structure is simple, light, and easily processes;
(2) cost more than 60% is saved;
(3) transport, install, change conveniently, easy to use;
(4) sealing of blasting piece device can effectively be ensured.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model.
In figure, 1-intensity film, 11-gap, 12-screw, 2-gasket seal.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
A kind of single-layer metal film dust rupture disk, its structure as shown in Figure 1-2, is made up of intensity film 1 and gasket seal 2.Intensity film 1 is metallic film, three sides of this metallic film offers gap 11, to weaken intensity film strength.Gap 11 is provided with many, and be distributed on three sides of metallic film, the interval between each gap can be identical, also can be different, and in the present embodiment, the interval between gap 11 keeps identical, carrys out controlled blasting pressure by regulating the gap size between each gap.Gasket seal 2 is positioned at the both sides up and down of intensity film 1, is positioned at the outer of intensity film 1, and covers the gap 11 that intensity film 1 side is offered, and needs to ensure to seal between gasket seal 2 and intensity film 1.The outermost edges of intensity film 1 offers screw 12.
The gasket seal 2 used can be integrated gasket seal, or is mutually bondd by strip pad and form.Gasket seal 2 must cover the gap of intensity film, and it is firm to paste at the guarantee of the both sides of intensity intermembrane space and gasket seal, ensures the sealing of blasting piece device.
