Abstract
The utility model discloses a novel ultrahigh-pressure plug self-sealing device which comprises an ultrahigh-pressure cylinder, a cylinder plug and an ultrahigh-pressure sealing ring. The ultrahigh-pressure sealing ring sleeves the cylinder plug, the cylinder plug and the ultrahigh-pressure sealing ring are mounted in the ultrahigh-pressure cylinder from right to left, and a plurality of semicircular sealing rings are arranged on the contacting portion of the periphery of the ultrahigh-pressure sealing ring and the ultrahigh-pressure cylinder and the contacting portion of the side face of the ultrahigh-pressure sealing ring and the cylinder plug. The novel ultrahigh-pressure plug self-sealing device has the advantages that the novel ultrahigh-pressure plug self-sealing device is simple and unique in structure and effectively solves the problem that an existing sealing device for an ultrahigh-pressure cylinder cannot meet use requirements, and the sealing performance is improved.
Description
Technical field
The utility model relates to sealing and leakage-proof device, particularly a kind of plug self-seal device of ultrahigh pressure cylindrical shell.
Background technique
Superhigh pressure technique in China still in the starting stage, the research of its hermetic unit plays an important role to the development of superhigh pressure technique, because traditional sealing means can only use under lower pressure, under extra high voltage system, its structure cannot ensure the sealing of equipment, for ensureing the normal safe operation of extra high voltage system, the improvement and bring new ideas on extra high voltage system seal arrangement is the problem that needs solution.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of plug self-seal device of ultrahigh pressure cylindrical shell, and the seal arrangement that can effectively solve existing ultrahigh pressure cylindrical shell can not meet the problem of use needs.
The technological scheme that the utility model adopts is: a kind of novel ultrahigh pressure plug self-seal device, comprise ultrahigh pressure cylindrical shell, cylindrical shell plug and ultra-high voltage sealing ring, ultra-high voltage sealing ring is set on cylindrical shell plug, cylindrical shell plug and ultra-high voltage sealing ring right-to-left pack in ultrahigh pressure cylindrical shell, and ultra-high voltage sealing ring external diameter and ultrahigh pressure cylindrical shell contact segment, ultra-high voltage sealing ring side and cylindrical shell plug contact segment all have multiple semicircle seal rings.
As preferably, it is stepped that described cylindrical shell plug is cylinder, is divided into three rank, increases successively from left end to right-hand member external diameter, angled transition between left end the first rank and second-order, ultra-high voltage sealing ring is inserted in to angled transition and cooperatively interacts from the left end of cylindrical shell plug.
As preferably, described ultra-high voltage sealing ring outside and the inwall close contact in ultrahigh pressure storehouse, and be provided with outer seal ring, inner side incline section is provided with side sealing ring.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, unique, improve sealing, and the seal arrangement that effectively solves existing ultrahigh pressure cylindrical shell can not meet the problem of use needs.
Brief description of the drawings
In order to be illustrated more clearly in the technical solution of the utility model, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is organigram of the present utility model;
Fig. 2 is the part enlarged view of the utility model Fig. 1;
In figure: 1, ultrahigh pressure cylindrical shell, 2, cylindrical shell plug, 3, cylindrical shell plug second-order, 4, side sealing ring, 5, outer seal ring, 6, ultra-high voltage sealing ring, 7, ultrahigh pressure storehouse.
Embodiment
In order more clearly to understand the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further illustrated.
Embodiment 1
As Fig. 1, a kind of novel ultrahigh pressure plug of the utility model shown in Fig. 2 self-seal device, comprise ultrahigh pressure cylindrical shell 1, cylindrical shell plug 2 and ultra-high voltage sealing ring 6, ultra-high voltage sealing ring 6 is set on cylindrical shell plug 2, cylindrical shell plug 2 packs in ultrahigh pressure cylindrical shell 1 with ultra-high voltage sealing ring 6 right-to-lefts, ultra-high voltage sealing ring 6 external diameters and ultrahigh pressure cylindrical shell 1 contact segment, ultra-high voltage sealing ring 6 sides and cylindrical shell plug 2 contact segments all have multiple semicircle seal rings 4, 5, the inwall close contact in ultra-high voltage sealing ring 6 outsides and ultrahigh pressure storehouse 7, and be provided with outer seal ring 5, inner side incline section is provided with side sealing ring 4, it is stepped that described cylindrical shell plug 2 is cylinder, be divided into three rank, increase successively from left end to right-hand member external diameter, angled transition between left end the first rank and second-order 3, ultra-high voltage sealing ring 6 is inserted in to angled transition and cooperatively interacts from the left end of cylindrical shell plug 2, the side sealing ring 4 on ultra-high voltage sealing ring 6 right sides is contacted with the left side of cylindrical shell plug 2 middle part second-orders 3.
Before 1 supercharging of ultrahigh pressure cylindrical shell, cylindrical shell plug 2 and ultra-high voltage sealing ring 6 are put into ultrahigh pressure storehouse 7 from ultrahigh pressure cylindrical shell 1 right side, and make the outer seal ring 5 of ultra-high voltage sealing ring 6 and the inwall close contact in ultrahigh pressure storehouse 7.
Between said adjacent side sealing ring 4 and outer seal ring 5, be plane structure, adjacent both sides sealing ring 4 top lines are parallel with the left side at cylindrical shell plug middle part 3, two adjacent outer seal ring 5 top lines are parallel with the inwall in ultrahigh pressure storehouse 7, ensure that at least one seal ring seals completely.
When the utility model uses, highly pressurised liquid enters ultrahigh pressure storehouse 7, and along with the increase of storehouse internal pressure, highly pressurised liquid is exerted pressure to seal ring from left side, and ultra-high voltage sealing ring 6 compresses with cylindrical shell plug middle part 3, ultrahigh pressure storehouse 7 inwalls.Ultra-high voltage sealing ring 6 is subject to the extruding generation deformation of ultrahigh pressure cylindrical shell 1, cylindrical shell plug 2, side sealing ring 4 is contacted and is become face contact from line with cylindrical shell plug middle part 3, outer seal ring 5 is contacted and is become face contact from line with the inwall in ultrahigh pressure storehouse 7, finally reach the effect of sealing, formed a kind of self-sealing system.Because working portion of the present utility model is by side sealing ring 4, outer seal ring 5, the face that deformation produces to occur to contact, therefore can reduce the requirement of the machining accuracy of sealing system, cut down finished cost.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
