Abstract
The invention relates to a two-way rupture disk safety device, which comprises an upper clamp holder, a rupture disk component and a lower clamp holder. After being assembled, the periphery of the rupture disk is welded in a spot way, and the rupture disk is arranged between the upper clamp holder and the lower clamp holder. The rupture disk component mainly comprises a strength film, a sealing film, a protecting film and a bracket. The sealing film is arranged between the strength film and the bracket. The protecting films are arranged among the sealing film, the strength film and the bracket. The strength film and the bracket are opened with slots weakening the strength of the materials. Compared with the prior art, the device has the advantages of stable and reliable performance, great bursting pressure difference range, good antifatigue performance, etc.
Description
Technical field
The present invention relates to a kind of rupture disk safety installations, the rupture disk assembly that refers more particularly to is mainly by forward and reverse two kinds of two-way rupture disk safety devices that pressure-sensing device constitutes.
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 now has been widely used in the equipment that industries such as chemical industry, medicine, environmental protection, iron and steel, electric power need protection.
Traditional slit type bursting disc is only applicable to unidirectional occasion of releasing (right arch slit type or inverted arch slit type bursting disc device).The existing inverted arch slit type bursting disc of claimant (number of patent application is 200820151632.8) mainly is made up of intensity film, protective film and sealing film, and hoop cracks on the intensity film arch face; The right arch slit type bursting disc is made up of intensity film, protective film, sealing film and carriage, and this two classes rupture disk is put on market.But along with developing rapidly of modernized mega project, constantly the widening of rupture disk application is at some special operation conditions; the malleation and the negative pressure that need the control container in these occasions, just need to install a kind of rupture disk; can realize forward and reverse explosion, to reach the purpose of protection equipment.
Domestic two-way rupture disk device mainly contains two kinds at present, and wherein a kind of its reverse explosion is the knife rest type, and the bursting pressure scope is little, can produce spark during explosion, is not suitable for inflammable and explosive medium.Another kind of two-way rupture disk device anti-fatigue performance is poor, is not suitable for the big occasion of pressure surge frequency.
Summary of the invention
Purpose of the present invention is exactly to provide the two-way rupture disk safety device that a kind of bursting pressure difference scope stable and reliable for performance, positive and negative is big, anti-fatigue performance is good for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: two-way rupture disk safety device; it is characterized in that; this device is made of last clamp holder, rupture disk assembly and lower gripper; the spot welding of rupture disk assembly assembling rear perimeter edge; be installed between clamp holder and the lower gripper; described rupture disk assembly mainly is made up of intensity film, sealing film, protective film and carriage; sealing film is arranged between intensity film and the carriage; be equipped with protective film between sealing film and intensity film and the carriage, have the seam that weakens the strength of materials on described intensity film and the carriage.
The pre-arch moulding earlier of described intensity film, hoop cracks on the arch face after the moulding, and perforate on arch face, described intensity zona is to the bursting pressure of minimum aperture when controlled blasting sheet forward is released at the place of cracking, when forward pressure reduction reaches the design bursting pressure, the at first section tension fracture of intensity film minimum aperture distance drives whole rupture disk and digs.
Described intensity film is a pressure-sensing device.
Described carriage encircles moulding in advance; on the arch face after the moulding, cut out the seam of dentation structure; bursting pressure when the long controlled blasting sheet of foot bridge at place of cracking is oppositely released; when reverse pressure reduction reaches the design bursting pressure; the long section tension fracture of foot bridge of carriage; sealing film is torn by the sawtooth of carriage, thus carriage sealing film protective film dig fully, medium is released by the hole on the intensity film arch face.
Described carriage is a pressure-sensing device.
Compared with prior art, rupture disk assembly of the present invention mainly is made of slit type bursting disc, on the positive intensity film of rupture disk and reverse side carriage, all have the seam that weakens the strength of materials, can realize the pressure release quick and precisely of rupture disk safety installations, allow the rupture disk pressure at both sides to change, any side pressure raises, when both sides pressure reduction reaches rupture disk design bursting pressure, and the rupture disk explosion.Have advantages such as stable and reliable for performance, positive and negative bursting pressure difference scope is big, anti-fatigue performance is good.

Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment 1
As shown in Figure 1: two-way rupture disk safety device comprises: go up clamp holder 1, rupture disk assembly 2 and lower gripper 3 and constitute.2 its peripheral spot welding of rupture disk assembly are installed between clamp holder 1 and the lower gripper 2.
Shown in Fig. 2～4: rupture disk assembly 2 is made up of intensity film 21, protective film 22, sealing film 23 and carriage 24, and sealing film 23 is arranged between intensity film 21 and the carriage 24, is equipped with protective film 22 between sealing film 23 and intensity film 21 and the carriage 24.
Shown in Fig. 5～6: intensity film 21 is pressure-sensing devices, intensity film 21 pre-arch moulding earlier, hoop cracks 4 on the arch face after the moulding, and perforate 5 on arch face, pressure release passage during as reverse pressure release is controlled the forward bursting pressure according to the bridge length that the place of cracking keeps, when pressure reduction surpasses bursting pressure, the intensity film is opened, thereby whole rupture disk is opened.The crack bursting pressure of minimum aperture when controlled blasting sheet forward is released at 4 places of intensity film 21 hoops, when forward pressure reduction reached the design bursting pressure, at first the section tension fracture of intensity film 21 minimum aperture distances drove whole rupture disk and digs.
Shown in Fig. 7～8: carriage 24 also is a pressure-sensing device; carriage 24 pre-arch moulding; the seam 6 that cuts out dentation structure on the arch face after the moulding is to weaken the intensity of carriage; control reverse bursting pressure according to the bridge length that 6 places of cracking keep; its dentation structure helps the unlatching of sealing film 23; oppositely during explosion; medium is released from the hole 5 on intensity film 21 arch faces; therefore can be according to the hole 5 on intensity film 21 arch faces; discharge area when the adjustment rupture disk is oppositely released; the carriage 24 long controlled blasting sheet of foot bridge at the 6 places bursting pressure when oppositely releasing that cracks; when reverse pressure reduction reaches design during bursting pressure, the long section tension fracture of foot bridge of carriage 24, sealing film 23 is torn by the sawtooth of carriage 24; thereby carriage sealing film protective film is dug fully, and medium is released by the hole 6 on intensity film 21 arch faces.
