Abstract
The utility model discloses the wire hole sealing structure on a kind of steam-turbine lubrication oil tank wall, it includes strap winding and extracts strap, the strap winding is centered on strap one end, the column structure of the other end successively winding, per between adjacent two layers strap many element lead-out wires are uniformly equipped with along the axial direction of the strap winding, and fluid sealant is filled between adjacent two layers strap, the two ends for extracting strap are respectively along the strap winding that axially penetrates through of the strap winding, and the two ends for extracting strap are located at the homonymy of the strap winding.Method of the utility model by sandwiching strap between fluid sealant filler so that in unit maintenance, can easily remove seal rubber plug, easily peel off wire and fluid sealant, both ensure that sealing effectiveness, and protect the technical parameter of element lead-out wire well.
Description
Technical field：
The utility model is related to a kind of sealing structure, and in particular to the wire hole sealing on a kind of steam-turbine lubrication oil tank wall
Structure.
Background technology：
Current steam turbine manufacturer, its respective grease-box element lead-out wire wire hole Sealing Technology mainly has two
Kind, one kind is filled using fluid sealant, and this encapsulating method can obtain preferable sealing effectiveness, will not typically produce permeability or
The situation of oil leak, but because all gaps are all shut with fluid sealant, in unit maintenance, the dismounting of lead will be extremely difficult, inspection
Repair difficulty big, generally require to use force and take out plug, be very easy to the insulation and shielding of damage wires；Another kind is to use
Oil resistant rubber plug is sealed, and this encapsulating method inspection operation is convenient, but sealing effectiveness is poor, due to element lead-out wire and rubber stopper it
Between cannot accomplish as fluid sealant filling it is tight, unavoidably have minim gap, lubricating oil can ooze out along gap.
Utility model content：
The purpose of this utility model is to provide the wire hole sealing structure on a kind of steam-turbine lubrication oil tank wall, solves mesh
The sealing effectiveness difference or the big problem of maintenance difficulty of preceding steam-turbine lubrication fuel tank element lead-out wire wire hole.
In order to solve the above-mentioned technical problem, the wire hole that the utility model is provided on a kind of steam-turbine lubrication oil tank wall is close
Seal structure, it includes strap winding and extracts strap, and the strap winding is the other end successively winding centered on strap one end
Column structure, per adjacent two layers straps between be uniformly equipped with many elements extractions along axial direction of the strap winding
Fluid sealant is filled between line, and adjacent two layers strap, the two ends for extracting strap are respectively along the axial direction of the strap winding
Through the strap winding, and the two ends for extracting strap are located at the homonymy of the strap winding.
Advantage of the present utility model：The utility model seals wire hole by strap winding, and every the two of strap winding
Filling with sealant between layer strap, because the cakey sealed gluing block of strap both sides can only be connected by strap mesh, this
Sample, equivalent to the intensity for reducing fluid sealant so that in unit maintenance, when with extracting strap and extracting strap winding, strap
Winding, fluid sealant and element lead-out wire are overall departs from from sealing hole, and when reusing external force and separating strap, sealed gluing block is by edge
Strap interface cracking, sealed gluing block can be easily removed, wire and fluid sealant is easily peeled off, sealing effectiveness is both ensure that,
The technical parameter of element lead-out wire is protected well again, while reducing labour intensity, has saved the repair time.
Brief description of the drawings：
Fig. 1 is the sealing interstitital texture schematic diagram of wire hole；
Fig. 2 is the A-A sectional views of Fig. 1.
Brief description of the drawings is as follows：1st, strap winding；2nd, strap is extracted；3rd, element lead-out wire；4th, wire hole.
Specific embodiment：
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
As shown in Figure 1-2, in embodiment of the present utility model, there is provided the outlet on a kind of steam-turbine lubrication oil tank wall
Hole sealing structure, it includes strap winding 1 and extracts strap 2, and strap winding 1 is that centered on strap one end, the other end is successively
The column structure of winding, draws per many elements are uniformly equipped with along the axial direction of strap winding 1 between adjacent two layers strap
Fluid sealant is filled between line 3, and adjacent two layers strap, the two ends for extracting strap 2 axially penetrate through cloth along strap winding 1 respectively
Band winding 1, and extract the homonymy that the two ends of strap 2 are located at strap winding 1.
Manufacturing process of the present utility model：During installation, it is 5 centimeters that width is made first, the suitable strap of length；Length root
According to wire hole 4 pore size determine, uniformly spread a thin layer acetone fluid sealant on cloth band so that two surfaces of strap all by
Fluid sealant is impregnated with, and takes an element lead-out wire 3, and the Fabric tape winding one that will be made is enclosed on element lead-out wire 3, sandwiches second
Element lead-out wire 3, clamp-ons proper amount of acetone glue between lead and strap, to fill minim gap, with same method, adjacent
Many element lead-out wires 3 are uniformly sandwiched between two layers of cloth band, the diameter with lead beam increases, often enclose the element entrained into adhesive plaster
The reasonable quantity of lead-out wire 3 increases so that bundle conductor is uniformly neat；When the quantity for entraining into wire reaches half of total amount or so,
One is sandwiched in a circle strap and extract strap 2, wherein extracting the two ends of strap 2 respectively positioned at the two ends of the circle strap；Treat institute
Have element lead-out wire 3 by all parcel finish after, continue wind daub strap, until winding after the diameter of strap winding 1 with
Bearing tank wall fairlead diameter quite, smear one and enclose acetone fluid sealant, for sealing wire hole 4 and cloth by last layer of strap appearance
With the gap between winding 1.
Due to being uniformly saturated with acetone fluid sealant, and the width of strap has 5 centimeters on two surfaces of strap, so that can
To ensure the seal degree of wire hole 4 well；When unit maintenance removes element lead-out wire 3, catch and extract strap 2, only need slightly
Micro- firmly one to draw, strap winding 1 will depart from wire hole 4, and due to there was only a small amount of fluid sealant between every layer of strap, find cloth
During the termination of band, as long as somewhat exerting oneself, the strap and element lead-out wire 3 in strap winding 1 will be easily peeled off very much without damaging
The insulation of element lead-out wire 3 and intensity.
Above is preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
Should be regarded as protection domain of the present utility model.
