Abstract
The utility model relates to a quick cap opening device for a supercritical CO2 high-pressure extracting kettle, which is composed of a pretension supporting ring, an O-shaped ring, a V-shaped ring, a triangular ring, a positioning bolt, a quick opening cap body and a clamp. The sealing performance is good because the pretension supporting ring collides to the slope of the kettle when the quick opening cap body is laid down, so the O-shaped ring is deformed to generate the initial seal. When the pressure is increased, the pretension supporting ring moves upwards and forces the V-shaped ring to expand so as to achieve the self-tightening seal. The utility model can be used for high-pressure and ultra-high pressure operation.
Description
The utility model relates to a kind of kettle cover device of supercritical carbon dioxide extracting still, particularly a kind of fast lid opening device for supercritical CO 2 high pressure extraction still.
Use the seal with O ring of hand extraction kettle in the prior art, general only with a seal with O ring.Because extraction kettle frequent intermittent operation under high pressure, CYCLIC LOADING and at supercritical carbon dioxide (CO
2) under high osmosis and the high-solvency, make O shape enclose very easily swelling and etch and damage, not only service life short, and be difficult to realize operation with high pressure.
The purpose of this utility model is to provide a kind of fast lid opening device for supercritical CO 2 high pressure extraction still, and its advantage is that the self-tightening sealing of sealing surface energy is applicable to high pressure, super-pressure operation.
Embodiment of the present utility model is as follows:
It is made up of pretension filler ring, O shape circle, v shaped ring, triangle ring, bolt, quick-actuating closure body and clip, described pretension filler ring, O shape circle, v shaped ring, triangle ring are the peripheries that is positioned at the quick-actuating closure body successively from the bottom up, and bolt is to pass the pretension filler ring to link to each other with the bottom of quick-actuating closure body, and clip is to be stuck on the upper periphery of quick-actuating closure body.
Advantage of the present utility model: O shape circle, v shaped ring, pretension filler ring combination sealing, good sealing effect can be used for high pressure, super-pressure extraction equipment, the potted component long service life, assembly and disassembly are very convenient.
Following preference combination accompanying drawing is described in detail the utility model.
Fig. 1 is a fast lid opening device for supercritical CO 2 high pressure extraction still sketch of the present utility model.As can be seen from Figure 1,10 ° of chamferings are arranged at kettle top.The following peripheral of quick-actuating closure body 6 is that combination sealing is pretension filler ring 1, O shape circle 2, v shaped ring 3 and triangle ring 4 from descending, and pass triangle ring 4 by bolt 5 and be positioned on the quick-actuating closure body 6, when putting into quick-actuating closure 6, pretension filler ring 1 is collided with kettle 8 ramps, O shape is enclosed 2 compressive deformations, produces initial sealing with kettle 8.And then clip 7 compresses quick-actuating closure 6, works as CO
2Boost, promote to move on the pretension filler ring 1, make further distortion of O shape circle 2, compressing v shaped ring 3 distendings have enlarged sealing surface, reach the effect of self-tightening sealing.This combination sealing can be used for high pressure, super-pressure operation.During dismounting since in pressed, remove clip 7, the quick-actuating closure 6 of slinging, pretension filler ring 1 glides along bolt 5, O shape circle 2, v shaped ring 3 resile, quick-actuating closure 6 is reusable just.
O shape circle 2, v shaped ring 3 in the combination seal can be placed reversed order in addition, can be from being pretension filler ring 1, v shaped ring 3 (spill is up), O shape circle 2, triangle ring 4 combination sealings down, the result combinations sealing effectiveness is constant.This combination sealing makes high pressure CO
2Directly do not contact, avoided CO with O shape circle 2
2Etch, prolong O shape and enclosed for 2 service lifes.
