Abstract
The utility model relates to an antiarch unstability welding type rupture disc device, its characterized in that includes rupture disk and holder, and rupture disk and holder weld into whole, and the rupture disk encircles the back concave surface side that takes shape in advance and sets up weak flute profile one -tenth antiarch unstability trough of belt rupture disk, weak groove processing blade shape is different. The utility model discloses rupture disk and holder be integral, the convenience of customers installation with change, avoid so the reason influences improper blasting in the work.
Description
Technical field
The utility model relates to a kind of rupture disk safety protection device, particularly relates to a kind of antiarch unstability Welding blasting sheet device.
Background technique
Rupture disk safety installations is the non-reclosing formula pressure-relieving device assemblied by rupture disk and clamp holder etc.At the rupture disk temperature of setting, when rupture disk pressure at both sides difference reaches predetermined value, rupture disk is action at once, and flowing medium of releasing out.For the protection of pressurized container or a kind of safe pressure relief device of pipeline.
Conventional blasting method sheet is Split assembled, and in particular circumstances, when requiring mounting point harshness, clamp holder and rupture disk are installed foreign matter when changing, have deviation, can cause product rupture disk pressure transient, easily explosion in advance.
Model utility content
The utility model is for above-mentioned problems of the prior art, and provide a kind of antiarch unstability Welding blasting sheet device, solve pressure transient in prior art, anti-unstability is weak, installs inconvenient problem.
The technical solution of the utility model is as follows:
Antiarch unstability Welding blasting sheet device, comprises rupture disk and clamp holder, and rupture disk and clamp holder are welded into entirety, and rupture disk encircles shaping back concave surface side in advance and arranges weak groove formation antiarch unstability trough of belt rupture disk; Weak slot machining cutting edge shape is different.
Described cutting edge shape is the blade of different amount.
The blade of described different amount comprises sharp knife sword and wide-angle blade, and the angle of sharp knife sword is 50-60 degree, and wide-angle knife edge angular is 60-65 degree.
Described weak groove is cross.
Described clamp holder comprises entrance clamp holder and outlet clamp holder, and entrance clamp holder clamps rupture disk with outlet clamp holder by the machine mode of folder.
The utility model has the advantages of as follows:
1, the utility model antiarch unstability Welding blasting sheet device compared with prior art, and rupture disk and clamp holder are integrated type.Facilitate user installation and replacing, avoid improper explosion in therefore cause influence work.
2, have outside activity beneficial at antiarch unstability solder type rupture disk.Different choice cutting edge shape the utility model having been consolidated material (as stainless steel, nickel etc.) is also different.Rupture disk fatigue resistance is strong, opens effective after explosion.
3, the utility model inlet/outlet clamp holder is used for clamping rupture disk; Rupture disk and clamp holder ensure that sealing configuration by welding.
4, antiarch unstability Welding blasting sheet device, welding procedure sealing effect is better than existing technology.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of prior art blasting piece device.
Fig. 2 is prior art antiarch unstability cross schematic diagram.
Fig. 3 is structural drawing of the present utility model.
In figure, 1, weak groove, 2, entrance clamp holder, 3, rupture disk, 4, outlet clamp holder, 5, weld joint.
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 3, antiarch unstability Welding blasting sheet device, comprise rupture disk and clamp holder, clamp holder comprises entrance clamp holder and outlet clamp holder, entrance clamp holder 2 clamps rupture disk 3 with outlet clamp holder 4 by the machine mode of folder, rupture disk and clamp holder are welded into entirety by weld joint 5 again, by welding meet rupture disk clamping bore and entrance clamp holder accurately locate.Rupture disk encircles shaping back concave surface side in advance and arranges weak groove formation antiarch unstability trough of belt rupture disk, and rupture disk processes criss-cross weak groove 1 by assistant tool after being shaped, and this weak groove shape is according to the difference of rupture disk material, and the shape selecting blade is different.Ensure that this structure has stronger anti-de-stabilise, it is little that cutting stress is concentrated.Do not open after avoiding upset, do not reach requirement of releasing.The cutting edge shape of described weak slot machining different amount; The blade of described different amount comprises sharp knife sword and wide-angle blade, and the angle of sharp knife sword is 50-60 degree, and wide-angle knife edge angular is 60-65 degree.
