Abstract
The utility model relates to an inverted-arch, annularly arch face-slotted rupture disc safety unit, which comprises a strength membrane and a reinforcing ring; wherein, the strength membrane is a pre-arched membrane, the arch face of which is provided with an annular weakening slot; the annular weakening slot is provided with a notch; and the reinforcing ring, which is arranged on the strength membrane, is provided with dentiform notches and a tongue-shaped sheet. Compared with the prior art, the utility model is applicable to equipment and pipelines for gas-phase media as well as equipment and pipelines for fully liquid-phase media, and moreover, the bursting pressure distribution range is wide, so the application range is wider.
Description
Technical field
The utility model relates to rupture disk, is specifically related to antiarch hoop arch face cutting (YCH type) rupture disk safety installations.
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 only can be adapted to gas phase media when liquid phase medium borehole blasting (full rupture disk normally opened because blasting energy is not enough).By Fig. 1, Fig. 2 is existing antiarch cross cutting type rupture disk, and its structure is to have cross on intensity film 1 arch face to weaken groove 3, and is provided with the nameplate 4 of the side of releasing.The rupture disk of the type is put on market.But along with developing rapidly of modernized mega project, need in full liquid phase medium equipment or the pipeline to use the occasion of rupture disk more and more, and these occasion working pressures and bursting pressure very near (maximum service pressure often near bursting pressure of bursting sheet 90%) and do not have fragment and spark when requiring the rupture disk explosion, existing antiarch cross cutting type rupture disk safety installations can't satisfy market demands.
The model utility content
The purpose of this utility model is exactly to provide in order to overcome the defective that above-mentioned prior art exists that a kind of applicable situation multiregion is wide, the pressure range of applicable working condition is big, is active in one's movements, the antiarch hoop arch face Notch blasting sheet safety installations of good seal performance.
The purpose of this utility model can be achieved through the following technical solutions: antiarch hoop arch face Notch blasting sheet safety installations, this device comprises the intensity film, it is characterized in that, also comprise stiffening ring, described intensity film is the diaphragm of pre-arch moulding, and the arch face of this diaphragm is provided with hoop and weakens groove, and this hoop weakens groove and is provided with a breach, described stiffening ring is arranged on the intensity film, and this stiffening ring is provided with dentation groove and ligule sheet.
The fan-shaped angle of described breach is 90 °.
It is pressure-sensing device that described hoop weakens groove.
Dentation groove on the described stiffening ring and ligule sheet are positioned at intensity film concave surface corresponding part.
Described dentation groove is for opening the element that causes brokenly of intensity film, and described ligule sheet is to prevent from that the intensity film from tearing to cause the protecting component that fragment flies out.
The described intensity film one side setting side of releasing is provided with nameplate on this side of releasing.
The utility model mainly is made up of intensity film and stiffening ring, the intensity film is the diaphragm by pre-arch moulding, and on arch face, be carved with hoop and weaken groove, it is pressure-sensing device, and stiffening ring cuts out dentation groove and ligule sheet in advance, the dentation ledge helps the unlatching of intensity film, and the ligule sheet prevents that the intensity film from tearing so that fragment flies out.Compared with prior art, the utility model is not only applicable to the equipment and the pipeline of gas phase media, is applicable to the equipment and the pipeline of full liquid phase medium yet, and bursting pressure has a very wide distribution, so its occasion scope that is suitable for is bigger.Owing to weaken the difference of groove structure, and be processed with the structure of dentation and ligule on the stiffening ring simultaneously, the pressure range of the utility model institute applicable working condition is bigger, and have be active in one's movements, good seal performance, fatigue performance are good, its operating mode working pressure can reach bursting pressure 90%, do not have good characteristics such as fragment and spark when opening.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 3～7, antiarch hoop arch face Notch blasting sheet safety installations, this device comprises intensity film 1, also comprises stiffening ring 2, the intensity film 1 one side settings side of releasing is provided with nameplate 4 on the side of releasing.Described intensity film 1 is the diaphragm with coforming, the arch face of this diaphragm is provided with hoop and weakens groove 5, determine that according to the bore requirement of releasing hoop weakens the diameter of groove 5, hoop weakens groove 5 and is provided with a breach, the breach angle is 90 °, different according to explosion bore and pressure are selected the cutter of different amount to process hoop and are weakened groove 5, and the angle of cutter is between 30 °～60 °.Described stiffening ring 2 is arranged on the intensity film 1, on the stiffening ring 2 at the concave surface place of intensity film 1, be provided with dentation groove 21 and ligule sheet 22 during stiffening ring 2 assembling, its dentation groove 21 helps the unlatching of intensity film, its ligule sheet 22 prevents that the intensity film from tearing so that fragment flies out, and the thickness of its material and concrete shape are to determine according to explosion bore and bursting pressure.
Hoop weakens groove 5 and is pressure-sensing device, and dentation groove 21 is for opening the element that causes brokenly of intensity film, and ligule sheet 22 causes the protecting component that fragment flies out for preventing that the intensity film from tearing.
