Description
Technical field
The invention belongs to cable penetration Seal Design fields, and in particular to a kind of sealing to through the wall for odd-shaped cross section cable
Device.
Background technology
Cable is when across closed container, in order to ensure the sealing performance of closed container, needs to carry out specially through walls close
Envelope design.At present, engineering field mostly carries out sealing to through the wall using seal socket for wall penetration.Seal socket for wall penetration is mounted on first close
It closes on chamber wall, installation interface is sealed using O-ring, and for seal socket for wall penetration after installation is complete, one end is located at sealed compartment
Interior, the other end is located at outside sealed compartment, this both ends forms electric pathway with the cable connector inside and outside closed container respectively.Substantially, should
Method is by a cable across being split as two sections at closed container wall, and connect this two sections using seal socket for wall penetration
Come.In practical engineering application, the considerations of for certain special engineering factors, some cables do not allow for splitting, such case
It is lower to need to design special sealing to through the wall structure.
Invention content
The technical problems to be solved by the invention are to provide a kind of wall-through sealing device for odd-shaped cross section cable.
The wall-through sealing device for odd-shaped cross section cable of the present invention, its main feature is that：The wall-through sealing device packet
Include seal receptacle and casting glue；The bottom of the seal receptacle is pedestal, has boss on pedestal；The center of the pedestal has logical
There is seal groove in hole on pedestal around boss, and the circumferential annular of pedestal is evenly distributed with mounting hole；Have what is penetrated through with through-hole in the boss
Encapsulation cavity；
The course of work of the wall-through sealing device is as follows：
Cable is pierced by successively through encapsulation cavity and through-hole, and casting glue is perfused in encapsulation cavity and through-hole and cures, O-ring seal
It is placed in seal groove, pedestal is fixed on by mounting hole on closed container wall, completes sealing to through the wall.
The material of the seal receptacle is one kind in aluminium alloy or titanium alloy.
The casting glue is one kind in pure epoxy glue, epoxy polyurethane glue or Thomas's glue.
Seal receptacle in the wall-through sealing device for odd-shaped cross section cable of the present invention is Nian Jie with cable by casting glue
It is integrated, the bonding location of seal receptacle can be determined according to design requirement.Corresponding position is provided with seal receptacle peace on closed container wall
Threaded hole is filled, is blind hole structure.During use, seal receptacle is mounted on closed container wall using uniformly distributed bolt.Cable
Sealing to through the wall realized by two seals link：Sealing of first of sealing part between seal receptacle and cable, through embedding
After processing, the gap between cable and seal receptacle is all filled by casting glue, and sealing is realized by good bonding curing performance
Sealing in seat；Second sealing part is the sealing between closed container wall and seal receptacle, and seal groove is provided on seal receptacle,
Effective sealing outside seal receptacle can be realized using widely used O-ring seals.The present invention for odd-shaped cross section cable
Wall-through sealing device eliminates all channels of outer gas flow in cable penetration link, effectively prevents the disengaging of gas.This
The wall-through sealing device for odd-shaped cross section cable of invention has the advantages that simple in structure, sealing performance is reliable, suitable for more
The cable of kind cross sectional shape, such as circle, pancake, ellipse, polygon, pentagon etc., do not need to split on cable
It is two sections, as the important supplement of seal socket for wall penetration, can be applied to the sealing to through the wall design of particular/special requirement.
