Utility model content
The purpose of this utility model is to provide a kind of submerged cable and connects sealing device, its strong adaptability, seal reliable and simple in structure.
To achieve these goals, technical solution of the present utility model is: a kind of submerged cable connects sealing device, comprise sealing matrix, compress plug screw and seal plug, sealing matrix center is provided with through hole, this through hole comprises circular cylinder shaped portion and the circular cone shape part of convergent from top to bottom, the through-hole wall of circular cylinder shaped portion is provided with internal thread, compress plug screw outer wall and be provided with external screw thread, the center that compresses plug screw is provided with through hole, seal plug upper end is the upper frustum of a cone of flaring from top to bottom, lower end is the lower frustum of a cone of convergent from top to bottom, seal plug is provided with the through hole that power supply cable passes, seal plug is made by elastomeric material, compressing plug screw is screwed onto on the circular cylinder shaped portion through-hole wall that seals matrix, the through hole that compresses plug screw is the circular cone shape of flaring from top to bottom near one end of sealing matrix, described seal plug is arranged at described sealing matrix and compresses between plug screw.
The utility model submerged cable connects sealing device, wherein, the tapering of the circular cone shape part of the through hole on described compression plug screw equates with the tapering of the upper frustum of a cone of seal plug, and the circular cone shape that seals through hole on matrix tapering partly equates with the tapering of the lower frustum of a cone of seal plug.
The utility model submerged cable connects sealing device, wherein, on described sealing matrix, between the circular cylinder shaped portion of through hole and circular cone shape part, is provided with annular recess.
The utility model submerged cable connects sealing device, and wherein, described sealing matrix, compression plug screw all adopt metal material, and described seal plug is made by polytetrafluoroethylene or nylon material.
Adopt after such scheme, because connecting sealing device, the utility model submerged cable comprises sealing matrix, compress plug screw and seal plug, seal plug is located at sealing matrix and is compressed between plug screw, seal plug is made by elastomeric material and seal plug is provided with the through hole that power supply cable passes, by compressing plug screw, relative to sealing matrix, rotate, can make seal plug extrusion, various fit clearances are eliminated completely, can realize the positiver sealing that very flood is depressed, and, according to different cable sizes, through hole on processing seal plug correspondingly can be realized the sealing of different cables, sealing matrix can adopt various structures form to realize easily the application in different occasions, strong adaptability, and simple in structure.
In addition, because sealing matrix, compression plug screw adopt metal material, seal plug is made by polytetrafluoroethylene or nylon material, with low cost, can adopt conventional material to realize through conventional processing technology.
Accompanying drawing explanation
Fig. 1 is the cutaway view that the utility model submerged cable connects sealing device.
