Abstract
The utility model relates to a conical ultrahigh-pressure self-sealing system which can effectively solve the problems that the sealing performance in the ultrahigh-pressure system is poor so as to be able to meet requirements. The technical scheme is that the conical ultrahigh-pressure self-sealing system comprises a valve body and a connecting valve, wherein a conical surface at the front part of the connecting valve is arranged inside the valve body; the rear part of the connecting valve is fixed inside the valve body by an end closure; a plurality of semicircular sealing rings are arranged on the conical surface of the connecting valve; a through hole in the center of the connecting valve is communicated with a conical groove at the rear part of the connecting valve; a conical valve core is arranged inside the conical groove; a plurality of semicircular sealing rings are arranged on the conical valve core; and a spring is arranged in a hole through which the conical valve core is communicated with the connecting valve. The conical ultrahigh-pressure self-sealing system is unique in structure, convenient to use and good in sealing effect and is an innovative sealing device for the ultrahigh-pressure system.
Description
Technical field
Native system relates to the sealed against leakage system, particularly a kind of conical surface ultrahigh pressure selfsealings system.
Background technique
Superhigh pressure technique still is in the starting stage in China; 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 usual pressure; Its structure can't guarantee Seal of Equipment property under extra high voltage system, and for guaranteeing the normal safe operation of extra high voltage system, the innovation of the seal arrangement of extra high voltage system is the problem that needs solution.
Summary of the invention
To above-mentioned situation, for overcoming the defective of existing technology, the purpose of the utility model just provides a kind of conical surface ultrahigh pressure selfsealings system, can effectively overcome sealing difference and the problem that can not satisfy the demand in extra high voltage system.
The technological scheme of its solution is to comprise valve body and be connected valve that the conical surface that connects the valve front portion places in the valve body; The rear portion is fixed in the valve body by end cap; On the conical surface of connection valve a plurality of semicircle seal rings are arranged, intracardiac through hole is connected with the conical socket at rear portion in the connection valve, and taper valve core is housed in the conical socket; A plurality of semicircle seal rings are arranged on the taper valve core, taper valve core be connected the hole that valve is connected in spring is housed.
The utility model structure is unique, easy to use, and good sealing effect is the innovation on the extra high voltage system seal arrangement.
Description of drawings
Fig. 1 is the main pseudosection of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explain.
Provided by Fig. 1, the utility model comprises valve body and is connected valve, connects valve 4 anterior conical surfaces and places in the valve body 5; The rear portion is fixed in the valve body 5 by end cap 6; On the conical surface of connection valve 4 a plurality of semicircle seal rings are arranged, intracardiac through hole 7 is connected with the conical socket 8 at rear portion in the connection valve 4, and taper valve core 2 is housed in the conical socket 8; A plurality of semicircle seal rings 10 are arranged on the taper valve core 2, taper valve core 2 be connected the hole that valve 4 is connected in spring 3 is housed.
In order to guarantee using effect, between said taper valve core 2 and the connection valve 4 the corresponding spring fixed hole is arranged, spring 3 places in the spring fixed hole, and through hole 7 is connected with conical socket 8 through the spring fixed holes that connect in the valves 4.
There is connecting rod 9 at said taper valve core 2 rear portions, and taper valve core 2 is fixed on the spool bearing 1 through connecting rod 9.
Between said two continuous semicircle seal rings 10 is cone structure, and two halves circular seal ring top line is the structure parallel with internal conical surface, guarantees that at least one seal ring seals fully.
When the utility model uses, at first will connect valve 4 and be installed on the valve body 5, both rely on cone match; Again taper valve core 2 and spring 3 are installed in and are connected on the valve 4, then be fixed on taper valve core 2 on the spool bearing 1, use then end cap 6 with spool bearing 1 with to be connected valve 4 fixing; At this moment, the extruding force when connection valve 4 receives valve body 5 with valve gap 6 installations, the extruding that its protruding semicircle seal ring receives valve body 5 internal conical surfaces deforms; With contacting of valve body 5, connect valve 4 and the sealing fully of valve body 5 attachment portions quilt, under working condition by the contact of line contact becoming face; Highly pressurised liquid gets into from the sealing system left side, and taper valve core 2 moves right, valve open; Liquid flows into high-pressure chamber through spool bearing 1, and when high-voltage power supply stopped voltage supply, taper valve core 2 received the pressure from high-pressure chamber; Make it to compress with being connected valve 4, taper valve core 2 protruding semicircle seal rings receive the extruding that connects valve 4 internal conical surfaces and produce distortion, and its contact segment is by the contact of line contact becoming face; Finally reach the purpose of sealing, so just formed a kind of selfsealings system, because the working portion of sealing is the face contact that is produced by seal ring generation deformation; Therefore can reduce the machining accuracy of sealing system within the specific limits, effectively reduce processing cost.
The utility model structure is unique, easy to use, and good sealing effect is the innovation on the extra high voltage system seal arrangement.
