Detailed description of the invention
Fig. 1 is the low structural schematic diagram for rushing separating experiment device；
In figure: 1 pedestal, 2 separation rings, 3 shells, 4 initiators, 5 pistons, 6 separator disks, 7 points of valve nuts, 8 bolts.
Specific embodiment
The low separation simulation experiment analytical method that rushes of the invention is described in detail below, it is low to rush separation simulation experiment point
Analysis method, including following experimental procedure:
1, it establishes and low rushes separating experiment model.
(1) according to the low structure composition and working principle for rushing separator, the low each components for rushing separator are processed；
As shown in Figure 1, being the low structural schematic diagram for rushing separator, it includes pedestal 1, separation ring 2, shell 3, initiator
4, piston 5, separator disk 6, divide valve nut 7 and bolt 8, shell 3 is fixedly installed on pedestal 1, is equipped on housing first end
Initiator 4, initiator work can blow shell.Multiple separation rings 2, multiple separation rings are equipped in the inside of second end of the housing
Spaced set on the same circumference is equipped in the inside of separation ring and divides valve nut 7, and dividing valve nut includes identical three
Point, divide the outer wall of valve nut to contact with the inner wall for separating ring, divides the inner wall of valve nut to be equipped with internal screw thread, in separation ring and shell
Under the action of divide valve nut to be cylindrical in shape structure.Be movably installed with bolt 8 on the base, bolt also with the inner thread that divides valve nut
Connection, it is relatively fixed between bolt and pedestal in shell, under the action of separating ring and divide valve nut in this way.In bolt and initiator
Between be equipped with separator disk 6, side where the first end to initiator of separator disk extends, in order to give after initiator work
Separator disk applies certain pressure；Piston 5 is additionally provided between ring with separating in separator disk.The second end of separator disk and divide valve nut
Inner wall contact can push the interior of point valve nut when initiator Work Promote separator disk is mobile to the side where bolt
Wall, and then accelerate that the radial of valve nut is divided to decompose, and then release and divide valve nut to the radial forces of bolt, bolt is rushing at this time
Power acts on lower and base-separation.
According to the low structure composition and working principle for rushing separator, to pedestal, separation ring, shell, initiator, piston,
Separator disk divides valve nuts and bolt to carry out reasonable material, and carries out scaled down according to the actual low separator that rushes, and add
Work goes out above each components.
(2) above-mentioned each components are assembled together, composition is low to rush separating experiment model.
2, the low separating experiment model that rushes the low installation for rushing separating experiment model: is mounted on fixed or movable workbench
On.
3, the installation of experimental monitoring instrument；
