All be need to reach after design pressure could explosion, such as patent application 201210044576.9, disclose a kind of antiarch shearing-type
Blasting piece device, including lower gripper, antiarch shearing-type rupture disk component and upper clamper, it is characterised in that：The lower clamping
The upper surface of device is provided with groove；The antiarch shearing-type rupture disk component includes shearing ring and antiarch shape rupture disk, the shearing
Ring is fixed on the antiarch shape rupture disk；The upper clamper includes upper clamper and buffer block, under the upper clamper
Surface is provided with the boss with the groove match on lower gripper, and the buffer block and the inwall of the upper clamper fix company
Connect；It is engaged by the boss on the groove on lower gripper and upper clamper and consolidates the antiarch shearing-type rupture disk component
It is fixed.Patent ZL200910047707.7 discloses a kind of two-way rupture disk safety device, and the device is by upper clamper, rupture disk group
Part and lower gripper are formed, and rupture disk assembling components rear perimeter edge spot welding, are installed between clamper and lower gripper, described
Rupture disk component is mainly made up of intensity film, diaphragm seal, diaphragm and bracket, and diaphragm seal is arranged between intensity film and bracket,
Diaphragm is equipped between diaphragm seal and intensity film and bracket, described intensity film weakens the strength of materials with being provided with bracket
Seam.
These rupture disks are all that need to reach could explosion after design pressure.When need rupture disk design burst pressure with
After the problem of shifting to an earlier date explosion down occurs, conventional all blasting piece devices can not meet such demand, to solve the above problems, full
Sufficient market and the demand of client, it is necessary to develop a kind of blasting piece device that can shift to an earlier date explosion effectively, stable.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of simple in construction, installation
Active unstable failure antiarch shape blasting piece device convenient and using stabilization.
The purpose of the present invention can be achieved through the following technical solutions：A kind of active unstable failure antiarch shape explosion is on chip
Put, including lower gripper, rupture disk and upper clamper, it is characterised in that also include hitting component, the device assembly is fixed on down
On clamper, counter-arch shaped blasting piece is hit after hitting component stress, causes antiarch shape rupture disk arch face to be damaged, it is shifted to an earlier date unstability
Upset, reach the purpose for pressure of releasing.
Described shock component includes thimble, sealing ring, pilot hole, front limit and rear spacing, described pilot hole setting
Rear spacing and front limit is provided with the side wall of lower gripper, and along pilot hole, described thimble is inserted out of pilot hole, passed through
Spacing afterwards and front limit, is stretched into lower gripper, and described sealing ring is arranged between thimble and lower gripper side wall, sealing ring
Sealed for O-ring, similar piston movement seals, and ensures not reveal during motion.When thimble stress, thimble is transported forward along pilot hole
It is dynamic, move at front limit, just strike on rupture disk, make its unstability.
The head of described thimble is relative with the position that rupture disk is most weak.
Described pilot hole is the angling hole being arranged in the side wall of lower gripper, makes thimble of the insertion in it and lower clamping
Angle between device side wall is 15-75 degree.
Described front limit is that the shaft shoulder is spacing, including is located at the boss of thimble side wall, and is arranged on lower clamping wall side wall
Interior groove, the groove match with the boss, and thimble moves to groove stop motion.
It is described it is rear it is spacing be the circlip for being arranged on pilot hole afterbody.
Under normal use, thimble is in contraction state, is not contacted with rupture disk；
When needing rupture disk unstability to overturn, thimble is stretching state, hits rupture disk arch face, destroys its upset.
Rupture disk part is usually counter-arch shaped.The failure mechanism of antiarch shape rupture disk is unstable failure, antiarch shape rupture disk
Correct mounting means is that arch face is installed towards pressure source, if wanting to make its effective unstability, percussion device is necessarily mounted at high-pressure side.
Lower gripper and upper clamper are that screw thread screws or flange is to folder.
Compared with prior art, the present invention has following items advantage：
(1) structure is simpler, makes, be easy for installation；
(2) it is active in one's movements, is not limited by rupture disk design pressure；
(3) manufacture, use cost are low；
(4) using reliable and stable；Rupture disk should first be designed and produced before design by hitting part, after the sagitta determination of rupture disk
The installation site and thimble length of percussion device are determined further according to the sagitta of rupture disk.Lower clamping device is provided with front and rear limit
Position, front limit be the shaft shoulder it is spacing, it is rear it is spacing for circlip it is spacing.When needing advancement, thimble by gas or electric drive, to
It is interior to be moved along a straight line along pilot hole, the most weak part of antiarch shape rupture disk is hit and pit occurs, forces rupture disk to lose in advance
Steady upset；
(5) advancement pressure is made by oneself for client, according to pressure is actually needed, actively destroys.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the magnified partial view that the present invention hits component.
Embodiment
