Abstract
The invention relates to the sealing device field, in particular to a sealing device for an ultrahigh pressure vessel. A chock plug is connected with a barrel of the ultrahigh pressure vessel by a screw thread. The tail end of the chock plug, which is close to one side of the interior of the barrel of the ultrahigh pressure vessel, is an inclined plane. The inclined plane coincides with a triangular washer of the sealing device to realize first resealing. The tail end of the chock plug is a cylinder. The chock plug is screwed into the interior of the barrel of the ultrahigh pressure vessel by the screw thread. The cylinder part of the chock plug coincides with an alloy ring, an O-shaped ring, a square-shaped ring and the like of the sealing device to realize second sealing. The sealing device has moderate softness and hardness, hard wearing, high pressure resistant property, and good sealing effect. The sealing device is arranged on a groove of the inner wall of the ultrahigh pressure vessel, is difficult to drop off and resistant to wear, has long service life and simple operation, and saves cost.
Description
Technical field
The present invention relates to sealing device field, particularly a kind of seal arrangement that is used for ultrahigh pressure vessel.
Background technique
The sealing configuration of ultrahigh pressure vessel is an important component part of whole super-high-pressure Food-processing Technology equipment, effective operation of food press will depend on sealing material select for use with sealing configuration rationally.Weigh the quality of superhigh pressure sealing structure, main according to following principle: as in normal working conditions, to guarantee the sealing effect of container; Simple in structure, make, adorn, tear open and overhaul conveniently; The sealing configuration compactness, seal element is few, and it is few to occupy high-pressure space; Required fastener constructions is simple, light and handy, to reduce weight of equipment; Good endurance.
Common several seal arrangements have:
A. forced seal: as plain cushion, Caza sealing, the sealing of single conical ring.Main dependence between sealed element and the Sealing has certain contact pressure, to reach sealing effect.Owing to cause the distortion of equipment and fastening piece after internal pressure rises, reduced contact pressure, suggestion is not used to ultrahigh pressure vessel.
B. semi-automatic seal: its representative form is the sealing of biconial ring.It has certain for sigma compactness, but along with the rising of pressure, because of its structural feature is limit, the contact pressure between seal element and the sealed element decreases, and actually still needs bigger pretightening force, and this has just limited its application area.
C. self-tightening sealing: as zero shape ring, C shape ring, B shape ring, triangle ring, wedge ring, Bridgman sealing, combined type etc.Because its structural feature, the contact force after pressure raises between seal element and top cover, the cylindrical shell end strengthens, and seals more effective; Pressure is high more, and sealing effect is good more, and this becomes the sealing first-selection of ultrahigh pressure vessel gradually.
All ultrahigh pressure vessel Sealings all are to be loaded on the plug at present, are external.Because food is big with the ultrahigh pressure vessel capacity, pressure is high, bore is big, add inevitably frequent keying the in the food processing process, make the external Sealing be out of shape or wearing and tearing, come off from end socket easily and need frequent the loading, working life is short, and because the improper Sealing that makes that material is selected cannot or hardly bear high pressure.
Summary of the invention
Main purpose of the present invention, be to overcome the shortcoming and defect of prior art, provide a kind of good sealing effect, high pressure resistant, use the seal arrangement simply be used for ultrahigh pressure vessel, it is characterized in that, plug 2 and ultrahigh pressure vessel cylindrical shell 1 are by being threaded togather, plug 2 is the inclined-plane near the tail end of ultrahigh pressure vessel cylindrical shell 1 an inner side, and the triangular washer 3 of this inclined-plane and seal arrangement coincide; The end of plug 2 is a cylinder, makes plug 2 screw in ultrahigh pressure vessel cylindrical shell 1 inside by screw thread rotation, and the cylinder part of plug 2 is coincide with the alloy circle 4 of seal arrangement, zero shape circle 6, shape circle 5.
Described seal arrangement is installed in the inboard wall groove of ultrahigh pressure vessel cylindrical shell 1.
Beneficial effect of the present invention is: by the combination that optimizes the arrangement of of various materials, obtain moderate, wear-resisting, the anti-high pressure of hardness (≤1000MPa) seal combination, thus reach optimum sealing effect; Described sealing group device is loaded on the ultrahigh pressure vessel inboard wall groove, and difficult drop-off is wear-resistant, and long service life is simple to operate, saves cost.

1-ultrahigh pressure vessel cylindrical shell; The 2-lower end cap; 3-delta-ring I; 4-delta-ring II; 5-shape circle; 6-zero shape circle.
Embodiment
The invention provides a kind of seal arrangement that is used for ultrahigh pressure vessel, the present invention will be further described below by description of drawings and embodiment.
Fig. 1 is a seal arrangement assembling schematic representation of the present invention, and Fig. 2 is an A position structure enlarged diagram among Fig. 1.Ultrahigh pressure vessel cylindrical shell 1 is provided with a dovetail groove near the outlet port, when assembling, in advance seal arrangement is installed in the dovetail groove of ultrahigh pressure vessel cylindrical shell 1; Plug 2 and ultrahigh pressure vessel cylindrical shell 1 are by being threaded togather, and plug 2 is the inclined-plane near the tail end of ultrahigh pressure vessel cylindrical shell 1 inner sides, and the triangular washer 3 of this inclined-plane and seal arrangement coincide, and realizes a resealing; The end of plug 2 is a cylinder, make plug 2 screw in ultrahigh pressure vessel cylindrical shell 1 inside by screw thread rotation, after triangular washer 3 fluid-tight engagement of the inclined-plane of plug 2 and seal arrangement, owing to continue to apply external force, the alloy circle 4, zero shape circle 6, shape circle 5 etc. of the cylinder part of plug 2 and seal arrangement are coincide, realize two resealings.
Alloy circle 4 of the present invention, zero shape circle 6, shape circle 5, the active force of external pressure will impel being close to mutually of junction plane during because of sealing, do not need connection very firm between junction plane, so not only make ultrahigh pressure vessel realize reliable sealing bearing under the situation of higher pressure, and can significantly reduce the volume and weight of seal arrangement.
Above-described embodiment is a preferable embodiment of the present invention, and those skilled in the art can make various modifications within the scope of the appended claims.
