Abstract
The utility model discloses an electric leakage preventing and insulating bolt, which comprises the composition of multilayer fiberglass cloth (1). An organic silicon adhesive layer (2) is provided between the glass fiberglass cloth. The electric leakage preventing and insulating screw cap, which comprises the composition of multilayer fiberglass cloth (1). An organic silicon adhesive layer (2) is provided between the glass fiberglass cloth. On the ground that the electric leakage preventing and insulating bolt and screw cap are formed by the composition of multilayer fiberglass cloth and the organic silicon glue is applied between the fiberglass cloth, fiber glass is full of silicon glue with good heat resistance up to 500 degrees and good insulating ability; the industrial frequency dielectric strength can be up to 20kv/mm with definite mechanical strength. The utility model can be used for parts which doesn't need too much mechanical strength on an electric stove with good insulating ability and simple mounting and operation.
Description
Technical field
The utility model relates to a kind of electric furnace accessory, a kind of anticreep insulated bolt and nut.
Background technique
Electric furnace is used in metallurgy and non-ferrous metal industry widely, a large amount of bolt, nuts that use various models on the electric furnace, and bolt and nut are all metallic article.In order to prevent bolt, charged, the electric leakage of nut,, between bolt, nut and conductive attachment, install mica washer and the mica sleeve pipe that is used for insulating usually additional with protection operator's safety.Each need be with two insulating washers and a spaghetti to bolt, nut.Increase the workload of installing and keeping in repair, also reduced the reliability of equipment.
Summary of the invention
The utility model is intended to propose a kind of bolt that insulating property are arranged and nut that suits to use, a kind of anticreep insulated bolt and nut on electric furnace.
This anticreep insulated bolt is composited mutually by multilayer woven glass fabric, is filling the organosilicon glue-line between the glass fiber cloth.
Also be composited mutually with the anticreep insulation nut that above-mentioned anticreep insulated bolt is used, filling the organosilicon glue-line between the glass fiber cloth for multilayer woven glass fabric.
This anticreep insulated bolt and nut, owing to be composited by multilayer woven glass fabric, bonding between the glass fiber cloth with organic silica gel, silica gel abrim between the glass fibre, good heat resistance, the high temperature that ability is 500 ℃, good insulation preformance, the power frequency dielectric strength can reach 20KV/mm, and certain mechanical strength arranged, use at position that can requirement of mechanical strength is not too high on electric furnace, has good insulation preformance, can simplify the characteristics of fitting operation.
Description of drawings
Accompanying drawing 1 is a kind of structural drawing of anticreep insulated bolt;
Accompanying drawing 2 is the another kind of structural drawing of anticreep insulated bolt;
Accompanying drawing 3 is a kind of structural drawing of anticreep insulation nut;
Accompanying drawing 4 is the another kind of structural drawing of anticreep insulation nut.
Embodiment
As shown in Figure 1, this anticreep insulated bolt is composited mutually by multilayer woven glass fabric 1, is filling organosilicon glue-line 2 between the glass fiber cloth.Glass fiber cloth shown in the figure parallels and stacks, and can coat superimposed behind the silica gel, pressurization, solidify with glass fiber cloth, makes plate, cuts into rod again, is lathed bolt at last.
As shown in Figure 2, the glass fiber cloth 1 in this anticreep insulated bolt also can become to intervolve shape.This structure intervolves, pressurizes, is solidified into bar after can glass fiber cloth being coated silica gel earlier, and reface becomes bolt.
As shown in Figure 3, also be composited mutually, filling organosilicon glue-line 2 between the glass fiber cloth by multilayer woven glass fabric 1 with the anticreep insulation nut that above-mentioned anticreep insulated bolt is used.Glass fiber cloth shown in the figure parallels superimposed, and working process also is to be combined into plate earlier, cuts into piece again, is processed into nut.
As shown in Figure 4, the glass fiber cloth 1 in this anticreep insulation nut also can become to intervolve shape.The nut of this structure, its blank are to intervolve the pole that forms.
Claims (4)
1, a kind of anticreep insulated bolt is characterized in that this bolt is composited mutually by multilayer woven glass fabric (1), is filling organosilicon glue-line (2) between the glass fiber cloth.
2, anticreep insulated bolt as claimed in claim 1 is characterized in that described glass fiber cloth (1) becomes to intervolve shape.
3, the anticreep insulation nut that is used of anticreep insulated bolts a kind of and claim 1 or 2 is characterized in that this nut is that multilayer woven glass fabric (1) is composited mutually, is filling organosilicon glue-line (2) between the glass fiber cloth.
4, anticreep insulation nut as claimed in claim 3 is characterized in that described glass fiber cloth (1) becomes to intervolve shape.
