As shown in Figure 1, the hollow insulator 100 that an embodiment of the present invention provides comprising insulation tube 110, first
Flange 130 and second flange 150.
Specifically, insulation tube 110 has the first segment 111 being arranged positioned at one end of insulation tube 110 and is located at insulation tube
The second segment 113 of 110 other end setting.First flange 130 has embedded division 131, and embedded division 131 is inserted into insulation tube 110
Inner cavity, and be tightly connected with the inner surface of the first segment of insulation tube 110 111.Second flange 150 has the with insulation tube 110
The sleeved part 151 that two section 113 of outer surface is tightly connected.
Hollow insulator 100, the inner surface that first flange 130 passes through embedded division 131 and the first segment 111 of insulation tube 110
It is tightly connected, to avoid forming gap between first flange 130 and the outer surface of insulation tube 110, and then avoids between this
Gap is sealed the process of processing, so that the manufacture craft of hollow insulator 100 is simple.
In addition, first flange 130 is tightly connected by embedded division 131 and insulation tube 110, first flange 130 and absolutely is avoided
Gap is formed between the outer surface of edge pipe 110, i.e., without being sealed processing to the gap, without first flange 130 again
Sealing ring is set between insulation tube 110, reduces production cost.
First flange 130 is tightly connected by embedded division 131 and insulation tube 110, it is possible to reduce outside first flange 130
Diameter reduces production cost to reduce the material utilization amount of manufacture first flange 130.
In the present embodiment, the outer surface of the second segment 113 of second flange 150 and insulation tube 110 is tightly connected, i.e., by the
Sleeved part 151 on two flanges 150 is set in the second segment 113 of insulation tube 110.The structure of second flange 150 with to install
The structure of the breaker of hollow insulator 100 is related.Specifically, gas access 153 is additionally provided in second flange 150.
Certainly, in a further embodiment, if difference occurs for the structure of breaker, the structure of second flange is also accordingly sent out
It is raw to change.Optionally, under the premise of meeting the installation of breaker, the sleeved part of second flange can also be embedded in the of insulation tube
In two sections, and it is connect with the inner surface of the second segment of insulation tube.In this way, also can further such that hollow insulator manufacture craft
Simply, production cost is reduced.
Optionally, in a further embodiment, the sleeved part of second flange can also simultaneously with the second segment of insulation tube
The inner surface and the outer surface is tightly connected.Optionally, the sleeved part of second flange is equipped with to the side to the second segment for insulation tube
The slot of wall insertion, so that the sleeved part of second flange and the inner surface and the outer surface of second segment are tightly connected simultaneously.
It is understood that insulation tube 110 can be the insulation tube customary in the art such as glass reinforced plastic pipe or porcelain tube.
Optionally, the roughness of the outer surface of the embedded division 131 of first flange 130 is more than or equal to 6.3 μm, and first segment
The roughness of 111 inner surface is more than or equal to 6.3 μm, to prevent the embedded division 131 and insulation tube 110 of first flange 130
The sliding of sealing structure between first segment 111, to help the sealed connection of embedded division 131 and the first segment 111 of insulation tube.
Specifically, the inner surface of the roughness and first segment 111 of the outer surface of the embedded division 131 of first flange 130 is thick
Rugosity can be 6.3 μm, 7 μm, 8.5 μm, 9 μm, 10 μm, 11 μm, 12.5 μm, 15 μm, 17 μm, 20 μm, 25 μm, 30 μm, 33 μ
M, 37 μm, 41 μm, 46 μm, 48 μm, 50 μm, 55 μm or 60 μm etc..
Preferably, the inner surface of the roughness and first segment 111 of the outer surface of the embedded division 131 of first flange 130 is thick
Rugosity is all larger than equal to 50 μm, so that the sealing of the first segment 111 of the embedded division 131 and insulation tube 110 of first flange 130
Connection effect is more preferable.
In the present embodiment, the direction of the inner cavity of insulation tube 110 is inserted into along embedded division 131, the length of first segment 111 is greater than embedding
Enter the length in portion 131.The internal diameter of first segment 111 is greater than the internal diameter of the other parts of insulation tube 110.Therefore it is inserted by embedded division 131
Behind the inner cavity for entering insulation tube 110, the first segment 111 of insulation tube 110 and the end of embedded division 131 surround groove 115.Work as insertion
When portion 131 is tightly connected by the inner surface of bonding agent and insulation tube 110, groove 115 can accommodate the bonding agent of spilling, prevent
Bonding agent arbitrarily flows to the inner surface of insulation tube, to avoid cured bonding agent to the performance of the inner wall of insulation tube 110
It influences.
In the present embodiment, first flange 130 has the edge 133 being bonded with the end face of first segment 111.Edge 133 is set
It sets, it is possible to reduce sealing structure between embedded division 131 and the inner surface of first segment 111 and extraneous contact, to avoid outer
Steam intrusion embedded division 131 in boundary's environment and the sealing structure between the inner surface of first segment 111.
Further, if can completely cut off being also connected and sealed between edge 133 and the end face of first segment 111 embedding
Enter the contact of the sealing structure and external environment between portion 131 and the inner surface of first segment 111, to further ensure insertion
The sealing reliability of sealing structure between portion 131 and first segment 111.
It is understood that embedded division 131 is inserted into depth of inner cavity sealing according to needed for hollow insulator of insulation tube 110
Performance is determined.It is understood that influencing to insulate if the depth of the inner cavity of the insertion insulation tube 110 of embedded division 131 is too deep
The area of the cavity of 110 inner cavity of pipe, influences the performance of hollow insulator 100.Embedded division 131 is inserted into the inner cavity of insulation tube 110
Depth is excessively shallow, then causes embedded division 131 and the overlapping area of the interior performance of first segment 111 smaller, thus embedded division 131 and first
The area of the sealing structure of the inner surface of section 111 is smaller, so as to cause the sealing of embedded division 131 and the inner surface of first segment 111
Effect is weaker.
And in the present embodiment, the setting at edge 133 can also be used to limit the interior of the insertion insulation tube 110 of embedded division 131
The depth on surface, the depth for preventing embedded division 131 to be inserted into insulation tube 110 are too deep or excessively shallow.
