Description
Technical field
The utility model relates to a kind of blasting piece devices, are controlled more particularly, to burst pressure by mandril, and rupture disk rises
A kind of mandril of sealing function controls pressure type blasting piece device.
Background technique
Blasting piece device is a kind of urgent pressure relief device by pressure differential, is divided into right arch according to the difference of pressure-bearing surface
Shape rupture disk, antiarch shape rupture disk and plate shaped rupture disk.It can the explosion under defined temperature and pressure, pressure of releasing, protect
Hinder the safety of people's life and national wealth.And in existing blasting piece device, the burst pressure of blasting piece device is by quick-fried
Fragmentation element itself determines.
Summary of the invention
The purpose of this utility model is to provide burst pressures to be controlled by mandril, and a kind of top that rupture disk seals
Bar controls pressure type blasting piece device.
The utility model is equipped with lower flange, casing, studs, upper flange, nut, locking nut, mandril, cover board, quick-fried
Fragmentation, bolt and supported flange；It is fixed between the lower flange and upper flange by studs and nut, lower flange and upper flange
Between be equipped with casing, the upper end of the mandril is fixed by passing through the locking nut in the middle part of upper flange, and the lower end of mandril is by passing through down
Cover board above flange is fixed, and rupture disk is located between cover board and lower flange, rupture disk be mounted on supported flange and lower flange it
Between, the cover board and rupture disk are bolted on lower flange.
It can be fixed by the studs of circumference uniform distribution and the nut of circumference uniform distribution between the lower flange and upper flange.
The casing of circumference uniform distribution can be equipped between the lower flange and upper flange.
The lower flange is preferably arranged in parallel with upper flange.
The metal round rod that both ends are machined with smooth arc surface can be used in the mandril.
The top center of the cover board is machined with smooth arc surface and mandril end face arc surface cooperates, and by supported flange
Internal hole positioning is placed in the top of rupture disk.
Plate shaped rupture disk can be used in the rupture disk, and the burst pressure of rupture disk itself is lower than the burst pressure of whole device
Power.
Compared with prior art, the utility model has the advantages that following prominent：
1) burst pressure is controlled by mandril.The utility model is according to the principle of mandril buckle in compression in the mechanics of materials, making
Pressure for rupture disk is transferred to mandril, and push rod structure is simple, and diameter and length are easy to control, easy processing.
2) rupture disk selection is unrestricted.Not contact medium when due to mandril work, the burst pressure of whole device
It is not influenced by medium temperature.And the blasting piece device of burst pressure is controlled by explosion piece element, the explosion of rupture disk itself
Pressure is influenced by medium temperature.It is particularly suitable for worst hot case.
3) rupture disk manufacture is reduced.Since mandril is the key part for determining burst pressure, rupture disk itself
Burst pressure only need to be lower than whole device burst pressure, i.e., it is rupture disk that pressure, which reaches the burst pressure of whole device,
Can pop pressure of releasing, and the burst pressure of rupture disk itself is not necessarily to manufacture according to original burst pressure franchise, reduce
The manufacture difficulty of rupture disk itself.
4) the utility model be suitble to small pressure, heavy caliber, worst hot case a kind of blasting piece device.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of the utility model embodiment.
Fig. 2 is push rod structure schematic diagram in Fig. 1.
Fig. 3 is the operation principle schematic diagram of Fig. 1 borehole blasting piece.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing,
In fig 1 and 2, the utility model embodiment be equipped with lower flange 1, casing 2, studs 3, upper flange 4, nut 5,
Locking nut 6, mandril 7, cover board 8, rupture disk 9, bolt 10 and supported flange 11；By justifying between the lower flange 1 and upper flange 4
The studs 3 of Zhou Junbu and the nut 5 of circumference uniform distribution are fixed, and the casing of circumference uniform distribution is equipped between lower flange 1 and upper flange 4
2, the upper end of the mandril 7 is fixed by the locking nut 6 for passing through 4 middle part of upper flange, and the lower end of mandril 7 is by passing through on lower flange 1
The cover board 8 of side is fixed, and rupture disk 9 is located between cover board 8 and lower flange 1, and rupture disk 9 is mounted on supported flange 11 and lower flange 1
Between, the cover board 8 and rupture disk 9 are fixed on lower flange 1 by bolt 10.
The lower flange 1 is arranged in parallel with upper flange 4.
The mandril 7 is machined with the metal round rod of smooth arc surface using both ends.
The top center of the cover board 8 is machined with smooth arc surface and 7 end face arc surface of mandril cooperates, and by supported flange
11 Internal hole positioning is placed in the top of rupture disk 9.
The rupture disk 9 uses plate shaped rupture disk, and the burst pressure of rupture disk itself is lower than the burst pressure of whole device
Power, rupture disk 9 is consistent with the outer diameter of supported flange 11, and is machined with the consistent circumference uniform distribution bolt of quantity, diameter
Hole, lower flange 1 are machined with the circumference uniform distribution threaded hole connecting with bolt 10, and rupture disk 9 is tightened by supported flange 11 and bolt 10
It is fixed on lower flange 1, the inner hole of supported flange 11 and 9 contact surface side of rupture disk is machined with circular arc chamfering.The locking nut 6
Bottom centre on be machined with smooth arc surface and 7 end face arc surface of mandril and cooperate, be connected through a screw thread and be fixed on upper flange 4
At center.The upper flange and lower flange are machined with the consistent circumference uniform distribution bolt hole of quantity, diameter, pass through studs
3 and nut 5 be connected and fixed, be cased with casing 2 consistent in length on studs 3, guarantee support to upper flange 4 and upper and lower
It is parallel between flange.
Referring to Fig. 3, during the work time, the compression of rupture disk 9 deforms, and is drawn into arch face 12, and pressure is passed through lid
Plate is transmitted on mandril, and mandril stress generates bending deformation.When pressure medium reaches the burst pressure force value of device, mandril bending
Unstability falls off, and then 9 explosion of rupture disk ejects cover board, so that pressure of releasing, protects system.In Fig. 3, label 11 is to compress
Flange.
