Abstract
The utility model relates to a safety device for an anti-arch groove welded rupture disc, which consists of an anti-arch groove rupture disc, an upper clamper, a lower clamper and a O-shaped ring, wherein the anti-arch groove rupture disc is welded between the upper clamper and the lower clamper; and the O-shaped ring is arranged between the anti-arch groove rupture disc and the lower clamper. Compared with the prior art, the utility model has the advantages of simpler and more compact structure, convenient installation, good sealing effect and the like.
Description
Technical field
The utility model relates to a kind of rupture disk safety installations, and the antiarch Notch blasting sheet and the upper and lower holder that relate in particular in this rupture disk safety installations are welded as a whole, and utilizes O type circle to guarantee sealing.
Background technique
The rupture disk safety installations is by pressure differential, non-automatic urgent pressure relief device of cutting out, and is mainly used in protection pressurized container, pipeline or other closed system, and it is avoided because of excessively superpressure or vacuum cause destroying.The rupture disk safety installations has been widely used in the equipment that industries such as chemical industry, medicine, environmental protection, iron and steel, electric power need protection now.
The antiarch cutting type rupture disk of domestic production at present all is and the supporting use of clamp holder, and rupture disk is loaded between the clamp holder, and clamp holder then places between the companion flange, as shown in Figure 1.Install with the process of changing rupture disk in, if the greasy dirt of the sealing surface between clamp holder and the rupture disk, granule foreign material etc. are not cleaned out, cause the improper explosion of leaking easily with rupture disk.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of structure simple more compact for the defective that overcomes above-mentioned prior art existence, and antiarch cutting solder type rupture disk safety installations easy for installation, that sealing effect is good.
The purpose of this utility model can be achieved through the following technical solutions: antiarch cutting solder type rupture disk safety installations, it is characterized in that, this device is made up of antiarch Notch blasting sheet, upper and lower holder, O RunddichtringO, described antiarch Notch blasting sheet is welded between the upper and lower holder, and described O RunddichtringO is arranged between antiarch Notch blasting sheet and the lower gripper.
Described antiarch Notch blasting sheet is the diaphragm of pre-arch moulding, and is provided with on arch face and weakens groove, is pressure-sensing device.
The described groove that weakens is cross or annular.
Described upper and lower holder is the clamping and fixing device of antiarch Notch blasting sheet.
Compared with prior art, the utility model antiarch cutting solder type rupture disk safety installations, rupture disk and clamp holder weldering are one, antiarch Notch blasting sheet fatigue performance is good except that having for this rupture disk safety installations, do not have the advantages such as fragment during explosion, compare with clamp holder with bore, outer diameter D of the present utility model is little, height H is little, so structure is simple more compact, sealing effect is good, user friendly installation and replacing, the possibility of minimizing rupture disk safety installations improper explosion in proper functioning.

Fig. 2 is the plan view of original technology antiarch Notch blasting sheet (cross);
Fig. 3 is the plan view of original technology antiarch Notch blasting sheet (annular);
Fig. 4 is that structure master of the present utility model looks and partly cuts open figure.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 4: antiarch cutting solder type rupture disk safety installations, this installs by antiarch Notch blasting sheet 1, upward clamp holder 2, lower gripper 3, O RunddichtringO 4 are formed, described antiarch Notch blasting sheet 2 is welded between clamp holder 2 and the lower gripper 3, soldering point 5 partly cuts open shown in the figure as Fig. 4 left side, weld seam 6 is shown in Fig. 4 the right, and described O RunddichtringO 4 is arranged on antiarch Notch blasting sheet 2 and last clamp holder 2 and lower gripper 3.Antiarch Notch blasting sheet 1 is the diaphragm by pre-arch moulding, and on arch face, be carved with and weaken groove, weakening groove and can be divided into cross (referring to Fig. 2) or annular (referring to Fig. 3), is pressure-sensing device, guarantees bursting pressure by selecting the suitable rupture disk material thickness and the degree of depth that weakens groove.Determine the inner diameter d of clamp holder according to the bore requirement of releasing, determine the outer diameter D of clamp holder, and the one side that contacts with rupture disk at upper and lower holder is by mach method processing welding groove according to user's flange bolt centre distance.Suitable O type circle is selected in inside and outside footpath according to clamp holder.With above-mentioned part combination, make each part be connected to an integral body by welding method, user friendly installation and replacing, the possibility of minimizing rupture disk safety installations improper explosion in proper functioning.
