Abstract
The anti-leakage reactance of superhigh pressure sealing is oozed connecting head, relates to mechanical technique, particularly link technology.The utility model comprises the male-pipe of nut segment and nut segment both sides, it is characterized in that, at the end face of male-pipe, is provided with groove, and the aperture of male-pipe is positioned at groove, or groove arranges around the aperture of male-pipe.The beneficial effects of the utility model are, compared with prior art, to have better sealing under ultra-high voltage environment.Because the utility model leaves a lowest compression surplus to elastomer seal, can effectively protect encapsulated coil, make it not by undue extrusion-deformation, thus maintenance sealing state that can be lasting for a long time.
Description
Technical field
The utility model relates to mechanical technique, particularly link technology.
Background technique
In the interconnection technique of extra-high tension unit, the deep-well equipment (for example oil well bottom hole pressure bomb) such as oil well particularly, need to consider the impact of pressure on sealing, because the degree of depth of some deep-well is up to more than 4 kms, bottom hole pressure bomb need to bear pressure more than 50MPA, and this has just proposed very high requirement to the connection sealing of this kind equipment.Slightly seepage will be damaged electronic component wherein.
Prior art is as Fig. 1, comprise male-pipe and nut segment, by nut segment one side at male-pipe, elastomer seal 4 (for example rubber seal) is set and realizes sealing, facts have proved that its sealability under ultra-high voltage environment is not good, tracing it to its cause, is that prior art easily occurs that excess compression seal ring causes its distortion infringement.
Model utility content
Technical problem to be solved in the utility model is that a kind of connected element being applied in ultra-high voltage environment is provided.
The technological scheme that the utility model solve the technical problem employing is, the anti-leakage reactance of superhigh pressure sealing is oozed connecting head, the male-pipe that comprises nut segment and nut segment both sides, end face at male-pipe is provided with groove, the aperture of male-pipe is positioned at groove, or groove arranges around the aperture of male-pipe, described groove is used for arranging elastomer seal.
Further, the aperture of male-pipe is positioned at groove, and groove is cylindrical, and coaxial with male-pipe.
Or groove arranges around the aperture of male-pipe, groove is ring.
The utility model also provides a kind of anti-leakage reactance of superhigh pressure sealing of oozing connecting head with the anti-leakage reactance of superhigh pressure sealing to ooze link, also comprises that elastomer seal, elastomer seal are embedded in groove, and its thickness is greater than the degree of depth of groove.
Described groove is cylinder shape groove, and the aperture of male-pipe is positioned at bottom portion of groove, and described elastomer seal is the cylindrical shape with through hole, and its through hole is coaxial with male-pipe.The geomery of elastomer seal and groove are adaptive.
Further, the through-hole aperture of elastomer seal is greater than the internal diameter of male-pipe.
Further, described groove is that described elastomer seal is also annular around the annular groove of the aperture setting of male-pipe.
The beneficial effects of the utility model are, compared with prior art, to have better sealing under ultra-high voltage environment.Because the utility model leaves a lowest compression surplus to elastomer seal, can effectively protect encapsulated coil, make it not by undue extrusion-deformation, thus maintenance sealing state that can be lasting for a long time.

Fig. 1 is the structural representation of prior art.
Fig. 2 is embodiment 1 structural representation.
Fig. 3 is embodiment 1 schematic perspective view.
Fig. 4 is embodiment 1 end view (being provided with elastomer seal).
Fig. 5 is embodiment 2 end view.
In figure, 1 nut segment, 2 male-pipes, 3 grooves, 4 elastomer seals, 20 screw threads, 21 apertures.
Embodiment
Embodiment 1: referring to Fig. 2,3,4.
The present embodiment comprises the male-pipe 2 of nut segment 1 and nut segment 1 both sides, and nut segment 1 is fixedly connected with male-pipe 2, a connecting tube with through hole of whole formation.Nut segment 1 and male-pipe 2 can be one-body molded, also can are fixedly connected with and be formed by separated parts.
The outer wall of male-pipe 2 is provided with screw thread 20, at the end face of male-pipe 2, is provided with groove 3, and the aperture 21 of male-pipe 2 is positioned at groove 3.Groove 3 is cylindrical, and coaxial with male-pipe 3, and groove 3 is for arranging elastomer seal.The aperture 21 of male-pipe 2 is positioned at groove 3.Elastomer seal 4 is embedded in groove 3, and its thickness is greater than the degree of depth of groove 3, to guarantee elastomer seal 4 pressurizeds under working state.The geomery of elastomer seal 4 should be adaptive with groove, and the groove of the present embodiment is cylindrical, and elastomer seal 4 is the cylindrical shape with through hole, and its through hole is coaxial with male-pipe 2.The through-hole aperture of elastomer seal 4 should be slightly larger than the aperture in the aperture 21 in groove 3, in order to avoid descend in working order " bottleneck " that forms pipeline after pressurized, reduces because the impact of pressurized deformation on aperture.Elastomer seal can adopt rubber ring.
In order to guarantee that the shape of elastomer seal 4 after pressurized do not have a negative impact, the elastomer seal 4 of the present embodiment be shaped as flat, for example, the thickness of Sealing is less than radius; As the groove 3 that limits elastomer seal position, be shallow slot, the degree of depth of groove is less than the radius of groove.
Measure of merit:
Utilize piston gauge as the device that produces pressure, utilize Plexol 201 as transmission medium, utilize large-scale climatic chamber as temperature control apparatus.Anti-leakage reactance is oozed laboratory data following (data are after a continuous several times experiment in month is observed and gather, and each experimental period is 10 hours):
When the field pressure meter that utilizes the utility model technology is tested in China test institute, because its good sealing effect has obtained test data satisfactory for result.
Embodiment 2: referring to Fig. 5..
The present embodiment comprises the male-pipe 2 of nut segment 1 and nut segment 1 both sides, and nut segment 1 is fixedly connected with male-pipe 2, a connecting tube with through hole of whole formation.
