Abstract
A reverse domed impression bursting disc is mainly used to solve the problems that the maximum work pressure of the pressure device of the prior domed bursting disc is restricted by the structure of the bursting disc, which can only reach 70 to 80 percents of busting pressure; the leakage area is small with fragments and is unable to link with the safety valve after the bursting disc explodes. The utility model, including a bursting disc body, is characterized in that the transit point between the reverse domed convex surface of the bursting disc body and a clamping plane is provided with an incomplete circumferential impression. The utility model has the advantages that the maximum work pressure of the pressure device is up to more than 90 percents of the busting pressure; after the bursting disc explodes, the leakage area is large and the bursting disc is complete without fragments and the utility model is also able to link with the safety valve; the bursting disc is compatible to the pressure device of different mediums, thus being widely applicable to high, medium and low pressure.
Description
Technical field
The utility model belongs to a kind of pressure releasing safety installations that is subjected to pressure device, particularly a kind of antiarch impression rupture disk.
Background technique
Be subjected to be equipped with on the pressure device safe pressure relief device at some pressurized containers or pressure piping etc., be used to prevent to be subjected to pressure device owing to superpressure goes to pot, the structure of this device is provided with a domed rupture disk that convex surface is outside, be installed in by holding element and be subjected on the pressure device, the pressure of system acts on the convex surface internal surface of rupture disk, when system overpressure, rupture disk explosion pressure release, there is following deficiency in the rupture disk of this structure: 1, the maximum service pressure of pressure unit is subjected to the restriction of rupture disk structure, can only reach the 70-80% of bursting pressure of bursting sheet; 2, after the rupture disk explosion, its discharge area is less, and fragment is arranged, and can not with the safety valve coupling; 3, can not dual-purpose for the pressure device that is subjected to of splendid attire different medium, even liquid or gas.
The model utility content
The utility model purpose provides a kind of antiarch impression rupture disk, can make the maximum service pressure that is subjected to pressure device reach more than 90% of bursting pressure of bursting sheet, after the rupture disk explosion, its discharge area is bigger, and complete no fragment, simultaneously can with the safety valve coupling, can dual-purpose splendid attire different medium be subjected to pressure device, be widely used in high, medium and low pressure.
The utility model purpose is achieved by the following technical solution: it comprises the explosion lamellar body, it is characterized in that: the antiarch convex surface of explosion lamellar body and clamping plane switching place are provided with incomplete circumference impression.
Incomplete circumference impression radian on the above-mentioned explosion lamellar body is 210 °-345 °
The utility model and existing product are relatively, has following advantage: can make the maximum service pressure that is subjected to pressure device reach more than 90% of bursting pressure of bursting sheet, after the rupture disk explosion, its discharge area is bigger, and complete no fragment, simultaneously can with the safety valve coupling, can dual-purpose splendid attire different medium be subjected to pressure device, be widely used in high, medium and low pressure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the cross section enlarged view of the incomplete circumference impression of rupture disk.
Embodiment
See Fig. 1-3, concrete structure is as follows: the explosion lamellar body is counter-arch shaped, its antiarch convex surface 1 is provided with incomplete circumference impression 4 with 2 switchings place of clamping plane, and not exclusively the radian of circumference impression 4 is 210 °-345 °, does not have fragment when keeping the complete and rupture disk explosion of discharge area to fly out.The utility model is assembled in by holding element 3 and is subjected on the pressure device.
Claims (2)
