Abstract
The utility model relates to an integral rupture disk device, which structurally comprises a rupture disk and a holder. The rupture disk and the holder are of an integrally formed structure. According to the technical scheme of the utility model, safety protection requirements on long-tube trailer and other mobile type pressure containers especially in middle-high voltage systems can be met. Meanwhile, the defects of a conventional rupture disk structure and a combined structure of a rupture disk and a fusible alloy plug in the prior art are overcome. That is to say, the pressure relief can be quickly realized at a predetermined bursting temperature under a predetermined bursting pressure. Simultaneously, the safety is ensured during the usage process. Compared with similar products, the relief outlet of the device can be completely opened after the bursting process. Moreover, the device is extremely strong in fatigue resistance, and can meet the requirements of the long-term usage. The maximum working pressure of the device can be 90% of an allowable minimum bursting pressure. The device is applicable to gaseous and liquid media. Meanwhile, the device has no requirement on the torque at an installation site, and is free of leakage.
Description
Technical field
The utility model relates to a kind of blasting piece device, relates in particular to a kind of global blowup sheet devices.
Background technique
In prior art, the blasting piece device structural type that mesohigh place is used divides following several: 1. welding type: rupture disk base sheet is welded on outlet(discharge) flange, then encircles shaping by hydraulic pressure pwc.This kind of form is only suitable for positive arch form structure, and the working pressure of device can only reach below 70% of rupture disk minimum burst pressure, on the place using, has significant limitation.2. common positive arch form: rupture disk is used in conjunction with specific carrier ring (shearing ring).The rupture disk working pressure of this kind of form can only reach below 70% of rupture disk minimum burst pressure, runs into pressure surge frequently, there will be and does not reach the bursting pressure of regulation and in advance explosion.3. rupture disk-easy fusing alloy plug composite structure: be widely used in portable CNG long-tube trailer, but this device is only reaching low melting alloy melting point after melting, rupture disk is explosion pressure release, has to a great extent certain potential safety hazard.
Mesohigh operating mode, working pressure are higher, more than 85%, and the pressure place of frequent fluctuation, said structure cannot meet the demands.
Model utility content
The utility model, for above-mentioned problems of the prior art, provides a kind of global blowup sheet devices, has solved mesohigh place rupture disk in prior art and has been difficult to meet the demands, and has the problem of potential safety hazard.
The technical solution of the utility model is as follows:
Rupture disk and clamp holder adopt integrated formed structure.
Described clamp holder is even slug, and evenly slug central authorities form film and are rupture disk.
Described film thickness is less than slug thickness.
The utility model has the advantages of as follows:
1,, in the time reaching eversion pressure, rupture disk overturns immediately and breaks in the joint of rupture disk and shell.
2, solve the safety protection demand of the transportable pressure vessels such as middle-and-high voltage system, particularly long-tube trailer, overcome the shortcoming of rupture disk structure and rupture disk-easy fusing alloy plug composite structure in the past simultaneously.Pressure release rapidly under the explosion temperature stipulating, bursting pressure can be realized, Security in use can be guaranteed again.
3, relatively have with like product, after explosion, bleed outlet is opened completely; There is extremely strong fatigue resistance, meet long-term user demand.Maximum service pressure can reach minimum 90% of the bursting pressure that allows.Be applicable to gaseous state and liquid medium.In erecting bed to moment of torsion no requirement (NR), zero leakage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, rupture disk, 2, clamp holder.
Embodiment
Below, with reference to accompanying drawing, the utility model is described in more detail in conjunction with the embodiments.
Embodiment
As shown in Figure 1, rupture disk 1 adopts integrated formed structure with clamp holder 2; Clamp holder is even slug, and evenly slug central authorities form film and are rupture disk, and film thickness is less than slug thickness.
Machining process of the present utility model is:
Material is prepared, and processes even slug profile, evenly in the middle of slug, is processing film, and hydraulic pressure pwc arch is shaped, and forms rupture disk.
The above is specific embodiment of the utility model and the know-why used, and any equivalent transformation based on technical solutions of the utility model basis, within all belonging to protection domain of the present utility model.
Claims (3)
1. global blowup sheet devices, is characterized in that rupture disk and clamp holder adopt integrated formed structure.
2. global blowup sheet devices according to claim 1, is characterized in that described clamp holder is even slug, and described rupture disk is film, and film is arranged on even slug central authorities.
3. global blowup sheet devices according to claim 2, is characterized in that described film thickness is less than slug.
