Description
Technical field
This utility model relates to machinery manufacturing technology field, is specifically related to a kind of blasting piece device.
Background technology
Rupture disk is a kind of by the urgent pressure relief device of pressure differential, difference according to pressure-bearing surface is divided into positive arch rupture disk, antiarch shape rupture disk and the compound rupture disk of flat board, pressure-bearing surface be concave surface for positive arch rupture disk, pressure-bearing surface be convex surface for antiarch shape rupture disk.Conventional a kind of plate compounding type rupture disk includes that 2 pieces are provided with the pressure-bearing flat plate cracked and are placed in diaphragm seal therebetween, pressure-bearing flat plate is pressure-sensing device, when its pressurized is higher than the pressurized of another side, and pressure reduction is when reaching its maximum pressure-bearing, pressure-bearing flat plate pressurized is by explosion of cracking, diaphragm seal explosion therewith, rupture disk forms pressure relief opening and superpressure is discharged, it is ensured that the safety of closed system.Adeciduate feature when compound slab rupture disk has easy to manufacture and explosion, is widely used on the pressure vessel of industry, pipeline or other hermetic containers such as chemical industry, petrochemical industry, chemistry, metallurgy, weaving.During use, by the pressure-bearing surface of flat board rupture disk towards the inside of hermetic container, under normal pressure difference, rupture disk is deformed towards another side (pressure release face) by pressure-bearing, but owing to the pressure in container is affected greatly by materialization factor, the pressure extremely unstable of hermetic container, time have bounce-back, when pressure falls after rise, the two sides of rupture disk forms the differential back in opposite direction with positive differential pressure, and differential back causes rupture disk to the contrary Direction distortion of blasting direction.This positive differential pressure and differential back in pressure vessel occur alternately, make continuous reciprocal transformation in the middle part of flat board rupture disk, and in this case, the flat board rupture disk that metal material makes loses resistance to compression effect and to be replaced soon.
Utility model content
This utility model purpose is to provide a kind of blasting piece device, to solve many defects that prior art deficiency causes.
A kind of blasting piece device, include lower gripper, pressure-bearing film, diaphragm seal, rupture disk and upper clamper successively, mutual clamping between described lower gripper, pressure-bearing film, diaphragm seal, rupture disk and upper clamper, described lower gripper is provided with the knife rest of outwardly convex, described pressure-bearing film is provided with the skeleton mated with knife rest, described diaphragm seal is PTFE plastic sheeting, and described rupture disk is provided with some through holes, and rupture disk is provided with emanant cracking.
Preferably, it is provided with reinforcing ring between described diaphragm seal and rupture disk.

It should be noted that and between described diaphragm seal 3 and rupture disk 5, be provided with reinforcing ring 4, protect diaphragm seal 3, also can malleation release.
In the present embodiment, it is provided with pressure cap 6 between described rupture disk 5 and upper clamper 7.
In the present embodiment, described knife rest 8 is in triangular pyramidal, it is simple to punctured diaphragm seal 3 to perform pressure release by knife rest 8 during vacuum.
Additionally, described rupture disk 5 is plate rupture disk, when facilitating high pressure, perform pressure release by opening to meet.
Based on above-mentioned; blasting piece device of the present utility model; reinforcing ring 4 protects diaphragm seal 3; also malleation can release, when knife rest 8 is easy to vacuum in triangular pyramidal, punctured diaphragm seal 3 to perform pressure release by knife rest 8, during the more convenient high pressure of plate rupture disk, perform pressure release by opening to meet; this kind of blasting piece device has simple in construction; advantage reasonable in design, easy to use, economic and environment-friendly.
As known by the technical knowledge, this utility model can be realized by the embodiment of other essence without departing from its spirit or essential feature.Therefore, embodiment disclosed above, for each side, all it is merely illustrative, is not only.All all comprised by this utility model in the range of this utility model or being equal to the change in the range of this utility model.
