Abstract
The invention discloses a two-way casing for power cables, comprising a two-way casing body, a first joint, a second joint, an upper shielding layer, a lower shielding layer, and a throttling control valve. The first joint and the second joint are respectively arranged at the two ends of the two-way casing body. The upper shielding layer is arranged in the upper side of the two-way casing body. The lower shielding layer is arranged in the lower side of the two-way casing body. The throttling control valve is arranged in the middle of the two-way casing body. Through the technical scheme, the two-way casing for power cables is provided with the upper shielding layer, the lower shielding layer and the throttling valve, has a good shielding effect, and further has a throttling control function.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of bilateral sleeve pipe for power cable.
Background technology
Electric cable fitting refers to that various cable in cable line is connected with centre and the continuing of terminal, and it forms conveying electric network together with cable; Electric cable accessories, mainly according to the characteristic of the construction of cable, had both met and had recovered the performance of cable, ensured again the prolongation of cable length and the connection of terminal.Generally be divided into terminal connection and centre to continue by its purposes, terminal connects and is divided into indoor terminal and outdoor terminal, and ordinary circumstance outdoor terminal refers to outdoor cable connector, and indoor terminal refers to the connection of cable and electrical equipment; Continue and be divided into through type and transition type two kinds in centre, the cable that two eradication edge structure types are identical is interconnected and is called through type, and the cable that two eradication edge structure types are different is interconnected and is called transition type.Electric cable accessories of a great variety, generally common are several as follows, all kinds respectively have feature and limitation, and any one technology all can not replace mutually.
But, at present for the bilateral liner shields weak effect of power cable, but also do not possess throttling controlling functions.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of bilateral sleeve pipe for power cable, and shield effectiveness is good, but also possesses throttling controlling functions.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of bilateral sleeve pipe for power cable, comprise: bilateral sleeve body, first joint, second joint, upper shielding layer, lower screen and throttling control valve, the two ends of described bilateral sleeve body are respectively arranged with the first described joint and the second described joint, described upper shielding layer is provided with in the upper side of described bilateral sleeve body, described lower screen is provided with in the downside of described bilateral sleeve body, described throttling control valve is provided with in the middle part of described bilateral sleeve body.
In a preferred embodiment of the present invention, the internal diameter of the first described joint is identical with the internal diameter of the second described joint.
In a preferred embodiment of the present invention, the thickness of described upper shielding layer is identical with the thickness of described lower screen.
In a preferred embodiment of the present invention, the thickness of described upper shielding layer is less than the thickness of described lower screen.
The invention has the beneficial effects as follows: the present invention is provided with upper shielding layer, lower screen and throttling control valve, and shield effectiveness is good, but also possesses throttling controlling functions.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the present invention for bilateral sleeve pipe one preferred embodiment of power cable;
In accompanying drawing, the mark of each parts is as follows: 1, bilateral sleeve body, the 2, first joint, the 3, second joint, and 4, upper shielding layer, 5, lower screen, 6, throttling control valve.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of bilateral sleeve pipe for power cable, comprise: bilateral sleeve body 1, first joint 2, second joint 3, upper shielding layer 4, lower screen 5 and throttling control valve 6, the two ends of described bilateral sleeve body 1 are respectively arranged with the first described joint 2 and the second described joint 3, described upper shielding layer 4 is provided with in the upper side of described bilateral sleeve body 1, be provided with described lower screen 5 in the downside of described bilateral sleeve body 1, in the middle part of described bilateral sleeve body 1, be provided with described throttling control valve 6.
In the present invention, the internal diameter of the first described joint 2 is identical with the internal diameter of the second described joint 3.
In the present invention, the thickness of described upper shielding layer 4 is identical with the thickness of described lower screen 5.
In the present invention, the thickness of described upper shielding layer 4 is less than the thickness of described lower screen 5.
The beneficial effect that the present invention is used for the bilateral sleeve pipe of power cable is: the present invention is provided with upper shielding layer, lower screen and throttling control valve, and shield effectiveness is good, but also possesses throttling controlling functions.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
