Abstract
The utility model relates to an integrated welding type rupture disk device comprising an alligator tooth-shaped piece and a rupture disk, wherein alligator teeth of the alligator tooth-shaped piece are evenly distributed on the inner circle of the whole alligator tooth-shaped piece and are connected with the rupture disk in a spot welding mode. The integrated welding type rupture disk device reduces tensile deformation. Meanwhile, after the integrated welding type rupture disk device is improved, the discharge area needed when the device carries out discharging is increased, and the discharging diameter is increased to be 95% from the prior 85%. When a protected device exceeds pressure, the rupture discharging area of the device is completely opened, and media are discharged more rapidly. The factors affecting the technical performance of the device are lowered to the maximum extent, the device is convenient to install and use by a user, and the quality problem caused when the rupture pressure of the device is not accurate due to improper installation is avoided. Meanwhile, the integrated welding type rupture disk device has the advantages that fragments are not produced after rupture, the fatigue resistance is good, and vacuum pressure can be borne.
Description
Technical field
The utility model relates to and a kind ofly prevents superpressure or occur the safety protection device of excessive vacuum for pressurized container, pipeline or other confined space, relates in particular to a kind of integral solder type blasting piece device.
Background technique
Along with the continuous enhancing of environmental protection consciousness, the mankind improve year by year to the requirement of clean energy resource.Rock gas is considered to fossil energy the cleanest on the earth: it has the rear lta of gasification, is easy to diffusion, and nontoxic, tasteless, is easy to the characteristics such as transportation and storage, makes to use increasingly extensive.The transportation industry of rock gas also grows up thereupon.LNG conveying trough tank car arises at the historic moment, and blasting piece device, for LNG conveying trough tank car provides safety protection, is the requisite device of LNG conveying trough tank car.
In prior art, be used in the blasting piece device on groove tank car, as shown in Figure 1, tensile buckling is large, and when protected equipment superpressure, device explosion discharge area can not be opened completely, and media discharge speed is slow; Prior art borehole blasting sheet devices is subject to the impact of its structure in addition, the pressure range using is lower, user is in installation process, owing to being subject to pipeline concentricity, parallel flange degree, the impact of the many factors such as bolt pretightening, can be affected the bursting pressure of blasting piece device significantly, sometimes setting exceeds permission bursting pressure scope and shifts to an earlier date explosion, has potential safety hazard.
Model utility content
The utility model, for above-mentioned problems of the prior art, provides a kind of integral solder type blasting piece device, has solved the tensile buckling of prior art borehole blasting sheet devices large, has the problem of potential safety hazard.
The technical solution of the utility model is as follows:
Comprise crocodile gear piece and rupture disk, the crocodile tooth of crocodile gear piece is evenly distributed on the inner ring of whole crocodile gear piece; The crocodile tooth of crocodile gear piece is connected with rupture disk spot welding.
Described rupture disk is counter-arch shaped.
Described rupture disk is welded on wall pipe periphery.
Described rupture disk is provided with gland.
Described gland is provided with plastic protective cap.
Described crocodile tooth is circular arc.
The crown of described crocodile tooth is towards the interior arch face of rupture disk.
The utility model has the advantages of as follows:
1, crocodile toothing is made to improvement, crocodile tooth is evenly distributed on the inner ring of whole crocodile gear piece, reduces tensile buckling.After improving, increase discharge area when device is released simultaneously, be increased to 95% by 85% of the original bore of releasing.In the time of protected equipment superpressure, device explosion discharge area is opened completely, makes media discharge rapider.
2, crocodile tooth is connected with rupture disk spot welding, rupture disk and the welding of wall pipe, adopt such welded structure, got rid of because the pressure range using is lower, user, in installation process, is subject to pipeline concentricity, parallel flange degree, the impact of the many factors such as bolt pretightening, can be affected the bursting pressure of blasting piece device significantly, sometimes arranges to exceed to allow bursting pressure scope and the problem of explosion in advance.The factor that affects device technique performance is reduced to greatest extent, facilitate user installation to use, avoid the inaccurate quality problems that occur of device bursting pressure that cause because of Rig up error.
3, there is following characteristic: after explosion, do not produce fragment simultaneously; Fatigue resistance is good; Can bear vacuum pressure.
4, the effect of gland and protective hat: gland plays the effect of compression in package unit, prevents from causing bursting pressure unstable not because of the depth of weld; Protective hat plays that protective gear is avoided being subject to colliding with etc. outer damage.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art blasting piece device.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is side structure schematic diagram of the present utility model.
In figure, 1, crocodile gear piece, 2, rupture disk, 3, wall pipe, 4, gland, 5, protective hat.
Embodiment
Below, with reference to accompanying drawing, the utility model is described in more detail in conjunction with the embodiments.
Embodiment
As Figure 2-3, comprise crocodile gear piece 1 and counter-arch shaped blasting piece 2, the circular arc crocodile tooth of crocodile gear piece 1 is evenly distributed on the inner ring of whole crocodile gear piece, and the crown of crocodile tooth is towards the interior arch face of rupture disk 2; The crocodile tooth of crocodile gear piece is connected with rupture disk spot welding.Described rupture disk is welded on wall pipe 3 peripheries; Rupture disk is provided with gland 4; Gland is provided with plastic protective cap 5.
The utility model working pressure under equipment normal operating condition is-0.1Pa(perfect vaccum); in the time that the vacuum layer between groove tank car inner bag generation leakage or inside and outside courage is destroyed; blasting piece device can become malleation by part by negative pressure work; in the time reaching device design bursting pressure interval; device explosion pressure release, protector tank car inner bag compressive deformation.
Machining process of the present utility model is: material prepare-is processed gland, rupture disk, crocodile tooth, thick walled tube-rupture disk and the spot welding of crocodile tooth and thick walled tube periphery welding-nut gland-installation plastic protective cap.
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.
