Abstract
A kind of gas-liquid two-phase high pressure the utility model discloses is without fragment counter-arch shaped blasting piece device, comprise, band subtracts the upper clamp holder (1) of energy device (5) and the lower gripper (2) of band small boss (6) and is placed in counter-arch shaped diaphragm (3) and stiffening ring (4) therebetween.On the concave surface of the spherical (7) of counter-arch shaped diaphragm, the annular that is shaped with adjacent compression limit (9) weakens groove (8), compress limit and be shaped with the counter-arch shaped diaphragm endless belt groove (10) that coordinates described small boss, the stiffening ring that is fixedly connected with toothed projections (11) and band cambered surface baffle plate (12) on the counter-arch shaped diaphragm of the one that is connected with compression limit, stiffening ring connects firmly between upper clamp holder and the junction plane of lower gripper by asymmetric localization pin (13).The utility model is applicable to vacuum, has fluctuation pressure, gas-liquid two-phase, high pressure operating mode, can demarcate 90% operation of bursting pressure, compared with the prior art, opens without advantages such as fragment, good airproof performance, bursting pressure are more stable while having explosion.
Description
Technical field
The utility model relate to a kind of in the time of Pressure-Container-Exceeding Pressure the automatic blasting piece device of release pressure.Especially a kind ofly can under gas-liquid two-phase, hyperbaric environment, open the blasting piece device without fragment.
Background technique
In prior art, the blasting piece device that be applicable to vacuum, have fluctuation pressure, can move under 90% operating mode of demarcation bursting pressure can only be selected antiarch shape blasting piece device, the blasting piece device that is wherein applicable to gas-liquid two-phase medium operating mode, can only adopt antiarch band " C " word grooved blasting piece device and antiarch band " C " word groove and " Y " shape folded tooth type blasting piece device.Although the blasting piece device of this suitable gas-liquid two-phase medium has advantages of that unlatching is effective, but it is large to require to weaken groove (8) diameter than counter-arch shaped diaphragm (3) annular just because of the diameter of its similar stiffening ring toothed projections function, so in the time that system pressure reaches setting pressure, when rupture disk convex surface pressurized unstability is overturn fast, potential energy can be larger, when particularly bursting pressure is larger, easily produce fragment, can cause pipeline or container to stop up, produce potential safety hazard, be also not suitable for the occasion that has safety valve to contact after device; Secondly, when bursting pressure is large, diaphragm can thicken relatively with stiffening ring material, and the instantaneous compression of explosion limit easily produces twitch, causes bursting pressure unstable.
Summary of the invention
The purpose of this utility model is for above-mentioned prior art Shortcomings part, provides a kind of and can under gas-liquid two-phase, hyperbaric environment, open without fragment, the more stable blasting piece device of bursting pressure.
The purpose of this utility model can reach by following measures.A kind of gas-liquid two-phase high pressure is without fragment counter-arch shaped blasting piece device, comprise, band subtracts the upper clamp holder 1 of energy device 5 and the lower gripper 2 with small boss 6 and is placed in counter-arch shaped diaphragm 3 and the stiffening ring 4 of both therebetween, it is characterized in that: on the concave surface of the spherical 7 of counter-arch shaped diaphragm 3, the annular that is shaped with adjacent compression limit 9 weakens groove 8, compress limit 9 and be shaped with the counter-arch shaped diaphragm endless belt groove 10 that coordinates described small boss, on the counter-arch shaped diaphragm 3 of the one that is connected with compression limit, be fixedly connected with toothed projections 11 and the stiffening ring 4 with cambered surface baffle plate 12, stiffening ring 4 connects firmly between upper clamp holder and the junction plane of lower gripper by asymmetric localization pin 13.
The utility model compared to existing technology tool has the following advantages:
1. without fragment.Owing to strengthening endless belt toothed projections diameter, to weaken groove diameter than diaphragm annular little, and when counter-arch shaped diaphragm unstability upset, stiffening ring can consume part energy, continues upset, run into and subtract energy device, diaphragm can twist on pole, can not produce fragment, thereby reaches the object of safety relief medium.
2. good airproof performance, bursting pressure are more stable.Owing to being designed with small boss on lower gripper, the little concave station on small boss and diaphragm is made during fabrication in the lump.On lower gripper 2, the height of small boss 6 is h2, and the endless belt groove 10 on counter-arch shaped diaphragm 3 is highly h4, h2, h4 meets: h2=h4, and concave, convex platform matching is good, can not produce and takes out limit phenomenon therefore compress limit when explosion, not only good airproof performance, can not cause dielectric leakage, and bursting pressure is also more stable.
