Abstract
The utility model discloses a major-diameter column type insulator for inserting a flange, which is provided with the flange (1) and the column type insulator (8), and is characterized in that: an epoxy fiber glass core rod (3) is provided with an outer-layer chamfer (4) matched with a flange chamfer (5) of a flange short pipe through an end part of the column type insulator with an outer layer (2) and an inner layer (7) being solidified. The major-diameter column type insulator for inserting the flange has the advantages that: the column type insulator is matched with the flange between connecting flanges through interference inserting, and has the obvious characteristics that the strength is high, the processing time is saved, and the service life is prolonged. The major-diameter column type insulator for inserting the flange is particularly suitable for flange connection of the major-diameter column type insulator with the diameter being larger than 130mm.
Description
Technical field
The utility model belongs to the insulator that uses in the power circuit, and definite saying is a kind of major diameter pillar insulator of plug-in mounting flange.
Background technology
The major diameter composite insulator that uses at present basically all is to be employed in to adopt between pillar insulator and the flange to process certain clearance with being connected of flange; Then with the structure of cement or adhesives; Such structure perhaps, can produce brittle failure and perhaps be extruded problems such as inefficacy after freezing because of moisture in the winter time after stressed.For addressing this problem, the designer of the utility model has done research in earnest, has proposed the goal of the invention of the utility model.
Summary of the invention
The goal of the invention of the utility model puts forward for the above-mentioned deficiency that overcomes present pillar insulator adpting flange existence.A kind of major diameter pillar insulator of plug-in mounting flange promptly is provided.
The technical solution of the utility model is to realize like this; The major diameter pillar insulator of this plug-in mounting flange; Have flange and pillar insulator, it is characterized in that the epoxy glass fiber plug has the outer chamfering that cooperates with the flange chamfering of flange short tube through the end outer and pillar insulator that internal layer solidifies.
The beneficial technical effects of the utility model is: pillar insulator cooperates through the interference plug-in mounting with flange between the adpting flange, has the intensity height, practices thrift machining period, improves the distinguishing feature in useful life.Be particularly suitable for the flange connection of diameter greater than 130 millimeters larger-diameter pillar insulator.The flange of having avoided existing major diameter pillar insulator is through cement or the brittle failure of Spring Festival holidays agent gap bonding problem, the problem of stressed compression failure.
Description of drawings
Accompanying drawing 1 is the cross-sectional view of the utility model.Sequence number in the accompanying drawings is: 1, flange, 2, skin, 3, the epoxy glass fiber plug, 4, outer chamfering, 5, the flange chamfering, 6, interior packed layer, 7, internal layer, 8, pillar insulator.
Embodiment
Below in conjunction with the embodiment that provides in the accompanying drawing, the structure and the use of the utility model is elaborated.With reference to accompanying drawing; The major diameter pillar insulator of this kind plug-in mounting flange; Have flange (1) and pillar insulator (8), it is characterized in that epoxy glass fiber plug (3) has the outer chamfering (4) that cooperates with the flange chamfering (5) of flange short tube through the end of the pillar insulator of outer (2) and internal layer (7) curing.
In order to make plug-in mounting more smooth, its angle design in said flange chamfering (5) is 30 to 60 degree, and the outer chamfering (4) of its said pillar insulator end is designed to 20 to 50 degree.
In order to guarantee that the pillar insulator behind the plug-in mounting has reliable stretching resistance, with the external diameter less than pillar insulator of the internal diameter design of its said flange, its diameter difference is: 0.05 to 0.5 millimeter.And the insulator that diameter is big is got relatively large numerical value.
During use, with the loose pillar insulator rod of skirt of the flange that processes and pillar insulator plug or compound silicon rubber, place on the workbench of forcing press, the opening pressure machine is pressed into the end of pillar insulator inner the getting final product of short tube of flange.
Claims (3)
1. the major diameter pillar insulator of a plug-in mounting flange; Have flange (1) and pillar insulator (8), it is characterized in that epoxy glass fiber plug (3) has the outer chamfering (4) that cooperates with the flange chamfering (5) of flange short tube through the end of the pillar insulator of outer (2) and internal layer (7) curing.
2. according to the major diameter pillar insulator of the described a kind of plug-in mounting flange of claim 1, the angle that it is characterized in that said flange chamfering (5) is 30 to 60 degree, and the outer chamfering (4) of pillar insulator end is 20 to 50 degree.
3. according to the major diameter pillar insulator of the described a kind of plug-in mounting flange of claim 1, it is characterized in that the external diameter of the internal diameter of said flange less than pillar insulator, its diameter difference is: 0.05 to 0.5 millimeter.
