Description
Technical field
The utility model relates to a kind of rupture disk safety devices, more particularly to the antiarch Notch blasting with back pressure bracket is on chip
It sets.
Background technique
Blasting piece device is the pressure releasing safety device assemblied by rupture disk and clamper etc..For protecting pressure
Container or pipeline are from a kind of safe pressure relief device for destroying by superpressure., discharge area simple with structure be big, sealing
The advantages that performance is good, reliable operation.It is best suited for working media large viscosity, has polymer deposits or corrosive nature by force and pressure
Power sharply increases, common safety valve protection on inefficient pressure vessel or pipeline.Blasting piece device is non-closed
Bleeder is started by the static pressure of entrance, by the rupture of compression film come pressure of releasing.In rupture disk application operating condition, warp
It often needs to meet and bears vacuum or backwards pressure duty, and guarantee superpressure explosion under forward demolition pressure.Conventional counter-arch shaped cutting
Rupture disk, which can only meet, can bear vacuum.
Summary of the invention
The present invention provides a kind of band back pressure aiming at the problem that existing antiarch Notch blasting sheet devices can not bear greater back-pressure
The antiarch Notch blasting sheet devices of bracket solve rupture disk in the prior art and are unable to satisfy asking of requiring under greater back-pressure operating condition
Topic.
Technical scheme is as follows:
Antiarch Notch blasting sheet devices with back pressure bracket, including counter-arch shaped blasting piece and clamper, the clamper
Including entrance clamper and outlet clamper, the bracket for bearing back pressure, the domed dome shape of bracket, arch are had on entrance clamper
Sieve pore is machined on shape bracket.
The rupture disk is that antiarch carves " ten " word groove profile rupture disk.
The entrance clamper and bracket are an integral structure.
The rupture disk arcuate surface height is consistent with the support height of entrance clamper.
The entrance clamper and outlet clamper periphery design has threaded hole, and rupture disk is installed on by pre-loading screw
Between entrance clamper and outlet clamper.
The backing thickness is 4-5 times of rupture disk thickness.
The utility model has the advantages of as follows:
1, the utility model rupture disk is antiarch " ten " word notch type rupture disk.Weaken in rupture disk concave panel with cross
Slot ruptures when explosion, no fragment along slot.It is heat-treated after rupture disk cutting, eliminates machining stress, guarantee the performance of rupture disk
Consistency.Secondary forming, guarantee rupture disk arcuate surface height and entrance clamper are carried out after rupture disk heat treatment with particular manufacturing craft
Support height is consistent, that is, can guarantee and work normally under greater back-pressure, also can guarantee at or about the predetermined burst pressure rupture to
It releases pressure.
2, the arch spherical surface bracket with sieve pore, arch spherical surface height and rupture disk arch are designed as at entrance clamper inner hole
Face height is consistent, does not generate plastic deformation when guaranteeing rupture disk by backwards to pressure, burst pressure is avoided to change.
3, the backing thickness with sieve pore is 4-5 times of rupture disk thickness, and it is below backwards can to bear 5 times of burst pressure of design
Pressure.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the overlooking structure diagram of Fig. 1.
In figure, 1, entrance clamper, 2, pre-loading screw, 3, outlet clamper, 4, rupture disk, 5, sieve pore, 6, bracket, arrow
A represents back pressure direction, represented by arrow B positive pressure direction.
Specific embodiment
Referring to attached drawing, the utility model is illustrated in more detail in conjunction with the embodiments.
Embodiment
As shown, the antiarch Notch blasting sheet devices with back pressure bracket, including counter-arch shaped blasting piece 4 and clamper, institute
The rupture disk stated is that antiarch carves " ten " word groove profile rupture disk；The clamper include entrance clamper 1 and outlet clamper 3,
Entrance clamper and outlet clamper periphery design have threaded hole, and rupture disk 4 is installed on entrance clamper 1 by pre-loading screw 2
Between outlet clamper 3；With the arch dome shape bracket 6 for bearing back pressure on entrance clamper, on arch dome shape bracket
It is machined with sieve pore 5, the rupture disk arcuate surface height is consistent with the support height of entrance clamper；Backing thickness is rupture disk
4-5 times of thickness.Entrance clamper and bracket are an integral structure.
Rupture disk 4 when by backwards to pressure, play a supporting role by bracket, guarantees that rupture disk does not generate plastic deformation.Explosion
For piece when by positive pressure superpressure explosion, pressure makes rupture disk overturn and open along cutting by the sieve pore on bracket.
Clamper periphery design has threaded hole, and rupture disk 4 is installed on the entrance clamper 1 and outlet clamper 3 of belt supporting frame
In, it is tightened with pre-loading screw 2 by given torque value, it is ensured that rupture disk is correctly installed and clamped.
Antiarch " ten " word notch type rupture disk anti-fatigue performance is superior, and what is born before blasting piece device explosion is that compression is answered
Power, the mechanism of explosion are equivalent to the compression of trough of belt shell when reaching buckling pressure, and unstability overturning is ruptured along slot simultaneously.Even if close to losing
Steady pressure, stress suffered by rupture disk also operates in elastic range still far below the yield limit of material when operation.Therefore, have
Extremely excellent anti-fatigue performance.Rupture disk cutting process when, have stress generation, by carry out heat treatment and it is secondary forming, guarantee it is quick-fried
The consistency of broken pressure.Bursting property is stablized, and rapid pressure release is safe and reliable.
Such structure can bear biggish back pressure, also ensure that the installation of rupture disk and service performance meet user and want
It asks.
The above is specific embodiment of the utility model and the technical principle used, any to be based on the utility model
Equivalent exchange on the basis of technical solution, belongs within the protection scope of the utility model.
