Abstract
The utility model discloses an antitheft insulating joint, which comprises an outer sleeve, an inner connecting pipe and an outer connecting pipe, wherein an external waterproof sealing ring, an insulating support ring, an internal insulating secondary sealing ring and an insulating pressure ring are arranged between the outer sleeve and the inner connecting pipe. Two internal primary sealing rings are respectively among the insulating pressure ring, the inner connecting pipe and the outer connecting pipe, and an internal secondary sealing ring is arranged between the outer sleeve and the outer connecting pipe. Sinker high-strength bolts are uniformly distributed on the end surface of a big outer circle of the outer connecting pipe, and the outer sleeve, the end surface of the outer connecting pipe and the sinker high-strength bolts are welded into integration by means of a weld bead. Because the outer sleeve, the end surface of the outer connecting pipe and the sinker high-strength bolts are welded into integration by means of the weld bead, the sealing of the insulating joint is more reliable. In addition, the theft-proof purpose is really realized.
Description
Technical field
The utility model relates to a kind of insulating joint, particularly relates to a kind of antitheft insulating joint that is used for petroleum pipeline.
Background technique
At present, be extensive use of insulating joint in pipelines such as oil, rock gas, chemical industry, the structure of insulating joint is varied, generally is insulation and sealing technique in order to solve insulating joint.The insulating joint of existing structure, overcoat and outer connecting pipe are easy to be disassembled, and cause oil stolen easily, can't reach real antitheft purpose.
The model utility content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, the antitheft insulating joint that provides a kind of overcoat and outer connecting pipe to be disassembled.
For achieving the above object, the technological scheme that the utility model adopted is: a kind of antitheft insulating joint, it comprises overcoat 3, inner connection tube 6 and outer connecting pipe 11, be provided with outside waterproof grommet 1 between overcoat 3 and the inner connection tube 6, insulation supporter ring 2, built-in electrical insulation secondary seal circle 4 and insulation pressure ring 5, insulation pressure ring 5 and inner connection tube 6, be respectively equipped with two inner once sealing circles 7 between the outer connecting pipe 11, be provided with inner secondary seal circle 8 between overcoat 3 and the outer connecting pipe 11, it is characterized in that: being evenly distributed with countersunk head high-strength bolt 9 on the described outer connecting pipe 11 big cylindrical end faces, is one with weld seam 10 with both and 9 welderings of countersunk head high-strength bolt at the end face of overcoat 3 and outer connecting pipe 11.
The utility model has the advantages that: the utility model makes that the sealing of insulating joint is more reliable, and has really realized antitheft purpose owing to the end face at overcoat and outer connecting pipe is one with weld seam with both and the weldering of countersunk head high-strength bolt.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Antitheft insulating joint as shown in Figure 1, it comprises overcoat 3, inner connection tube 6 and outer connecting pipe 11, be provided with outside waterproof grommet 1 between overcoat 3 and the inner connection tube 6, insulation supporter ring 2, built-in electrical insulation secondary seal circle 4 and insulation pressure ring 5, insulation pressure ring 5 and inner connection tube 6, be respectively equipped with two inner once sealing circles 7 between the outer connecting pipe 11, be provided with inner secondary seal circle 8 between overcoat 3 and the outer connecting pipe 11, be evenly distributed with countersunk head high-strength bolt 9 on the described outer connecting pipe 11 big cylindrical end faces, outer connecting pipe 11 reliably is connected with overcoat 3, and compress the insulation pressure ring 5, make inner once sealing circle 7 and inner connection tube 6 and outer connecting pipe 11 end faces form sealing, end face at overcoat 3 and outer connecting pipe 11 is one with weld seam 10 with both and 9 welderings of countersunk head high-strength bolt, reaches the antitheft purpose that manpower can't be dismantled.
