Preferably, described upper clamper and lower gripper have the through hole of releasing of same diameter, and upper gasket seal is with The internal diameter of gasket seal is not more than the diameter for through hole of releasing.
Preferably, annular groove, the external diameter and flat board of annular groove are provided with the inside edge of the upper surface of lower gripper The diameter of slit type bursting disc matches, and the inside edge of the lower surface of upper clamper is provided with annular boss.
Preferably, the external diameter of described annular boss and annular groove matches, and the height of annular boss is recessed less than annular The depth of groove.
Preferably, described upper gasket seal, flat board slit type bursting disc edge and lower seal pad piece be from top to bottom successively It is arranged between annular boss and annular groove.
Preferably, lower gripper is provided with screwed hole, and upper clamper is provided with counterbore, and screwed hole and counterbore are located at ring respectively Outside connected in star and annular boss, upper clamper and lower gripper are tethered by the clamp screw being located in counterbore and screwed hole Connect, flat board slit type bursting disc is clamped.
Preferably, flat board slit type bursting disc includes diaphragm seal and intensity film, and described annular-slotted is arranged on intensity film On.
Preferably, the diameter of through hole of releasing is released diameter not less than minimum requirement.
Operation principle of the present utility model is:
The blasting piece device is connected to using in equipment during use, when superpressure phenomenon occurs in rupture disk side medium, put down Plate slit type bursting disc, which circumferentially cracks to extract out between upper gasket seal and lower seal pad piece, to be opened, and realizes explosion, release Jie Matter, after such blasting piece device is installed, avoided for the low-down container of design pressure due to deformation caused by breather valve failure Accident is highly effective.
Compared with prior art, the utility model has the advantages that:
(1) the utility model is simple in construction, and assembling is easy, changes and easy to maintenance, and reliability is high, manufacturing cost and use cost It is low, it is easy to spread.
(2) internal diameter of gasket seal and lower seal pad piece is less than the diameter of annular-slotted on, so that upper-lower seal pad Piece clamps annular-slotted when in use, and lower seal pad piece is mainly sealed, and upper gasket seal may be used also in addition to sealing function To also act as the effect of adjustment burst pressure by adjusting its thickness, the diameter of annular-slotted can also play adjustment pressure Effect.
(3) part beyond upper clamper lower surface annular boss of the present utility model and lower gripper upper surface annular are recessed Part beyond groove contacts with each other when upper clamper connects with lower gripper, and the height of annular boss is less than the depth of annular groove The space of level altitude is arranged at degree, the bottom of annular boss and the bottom of groove, so as to the thickness by adjusting upper gasket seal Degree adjusts the chucking power to flat board slit type bursting disc, and then plays a part of adjusting burst pressure.
(4) it is active in one's movements, burst pressure is stable, is not limited by use environment.
(5) it is applied widely, the low-down container of the design pressure that is particularly suitable for use in.
(6) when superpressure phenomenon occurs in rupture disk side medium, flat board slit type bursting disc circumferentially cracks from upper sealing gasket Extract out and open between piece and lower seal pad piece, effective discharge area is big.
Brief description of the drawings
Fig. 1 is diagrammatic cross-section of the present utility model;
Fig. 2 is the main structure diagram of flat board slit type bursting disc of the present utility model.
