Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
All other embodiments obtained without making creative work shall fall within the protection scope of the present invention.
As shown in Figure 1 and Figure 2, the rupture disk safety device of a kind of automatic Prediction service life and replacement early warning in real time, including lower folder
Holder 1, rupture disk 2, upper clamper 3, deformation monitoring patch 4, gland head 5, signal wire 6, signal pickup assembly 7；
The lower gripper 1, rupture disk 2 and upper clamper 3 form the blasting piece device of real-time guard equipment, the deformation
Monitoring patch 4 is bonded in 2 surface of rupture disk, and the through-hole of adaptation gland head, the deformation monitoring are offered on the upper clamper
Patch 4 is connected to by signal wire 6 on signal pickup assembly 7, and the signal wire is clamped by gland head 5, clamper 3 in realization
Inner sealing；
The signal pickup assembly timely feedbacks the signal that deformation monitoring patch 4 is acquired.
Lower gripper 1, rupture disk 2 and upper clamper 3 form blasting piece device and realize sealing, and rupture disk 2 is moved for pressure
Make element, when superpressure occurs in equipment, rupture disk 2 ruptures in time, pressure of releasing.
Deformation monitoring patch 4 is bonded in 2 surface of rupture disk, and deformation monitoring patch 4 must not deposit the bursting property of rupture disk 2
In any influence, when rupture disk 2 deforms, the change of deformation physical quantity when deformation monitoring patch 4 can deform rupture disk 2
Change is transferred to signal pickup assembly 7 in a manner of electric signal by signal wire 6.
Signal pickup assembly 7 can timely feedback the deformation physical quantity when rupture disk 2 that deformation monitoring patch 4 is acquired deforms
Variation, and in the form of indicator light or digital display screen record and feed back, so as to it is direct, objectively understand explosion
The instantaneous operating conditions of piece 2.
Using the patent of the present invention of above-mentioned technical proposal, the fixed form of blasting piece device usually selects common flange to connect
Connect fastening；
As shown in Figure 1, it is assumed that the pattern of rupture disk 2 is right arch plain edition rupture disk, is pressed inside the equipment protected at this time
Power is service pressure, and the operating pressure ratio of rupture disk 2 should be not more than 70%, and the variation of the deformation physical quantity of rupture disk 2 should
It is zero, the content shown by signal pickup assembly 7 should be designated as rupture disk 2 and not deform at this time；
As shown in Figure 2, it is assumed that the pattern of rupture disk 2 is right arch plain edition rupture disk, and the equipment internal pressure protected is deposited
Multiple superpressure occurs in pressure oscillation but explosion does not occur for rupture disk 2, the operating pressure ratio of rupture disk 2 is more than 70% at this time, has
90-95% is likely to be breached, the model deformation of rupture disk 2 is the pressure-bearing of rupture disk 8 (after deformation), at this time rupture disk 8 (after deformation)
Ability has declined to a great extent, and for a long time there are during pressure oscillation inside equipment, explosion may occur at any time for rupture disk 2, it is possible to
It causes to release in advance under regular operating pressures, and then influences the safety of equipment, influence the normal operation of production.And the present invention is specially
A kind of automatic Prediction service life and the rupture disk safety device of replacement early warning in real time that profit is related to can be by the deformation physics of rupture disk 2
The variation of amount is converted into electrical signal form and feeds back, and so as to directly objectively predict the service life of rupture disk 2, works as rupture disk
When service life is reduced to critical value but explosion does not occur, timely alarm replaces rupture disk, so that it is guaranteed that rupture disk is safe
Normal operation.
In addition, corrosion resistance of the explosion sheet material to respective media and surrounding medium, actual use temperature, the temperature of rupture disk
Degree fluctuation, the practical operation ratio of rupture disk, other unpredictable factors such as incorrect installation and mechanical damage all can be to quick-fried
Fragmentation bursting property has direct influence, and then influences the service life of rupture disk, and therefore, patent of the present invention fills pressure releasing
The automatic Prediction service life put and Realtime Alerts, replace it is imperative.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe is described in detail the present invention with reference to foregoing embodiments, it will be understood by those of ordinary skill in the art that：Its according to
Can so modify to the technical solution recorded in foregoing embodiments either to which part or all technical features into
Row equivalent replacement；And these modifications or replacement, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
