Description

Technical Field

[0001] The present application relates to the technical field of insulating accessories, and in particular to an insulating joint. Background Art

[0002] The instrument system pipelines are generally composed of various monitoring instruments, transmitters, instrument valves, pipe fittings and other components. Among them, monitoring instruments and transmitters are electronic components and need to be powered on to work. During the operation of the system pipelines, various electronic components have different degrees of leakage risks. In the system pipelines in the fields of petroleum, chemical, natural gas, electricity, etc., flammable and explosive media are usually used. At this time, if there is a large amount of static electricity or pipeline leakage in the system pipeline, it may cause dangerous accidents such as fire and explosion, causing economic losses and personnel safety accidents. Insulating joints, while being used to connect system pipelines, also play the function of protecting the pipeline system. Its main function is to insulate and isolate the monitoring instruments and pipelines of the instrument system pipelines, and between the equipment and pipelines, to block the current conduction caused by leakage, and avoid the accumulation of static electricity in the main pipeline, thereby avoiding safety hazards in the instrument system pipelines.

[0021] When the joint needs to be repaired or disassembled later, it is only necessary to pull up the pull plate 9 by hand. After the pull plate 9 moves up, the two limit rods 12 will move up through the two connecting rods 10. At this time, the cross bar 13 is pressed again.

[0023] Insert the second insulating head 3 directly into the interior of the first insulating head 2, and align the two guide blocks 5 with the two guide grooves 7 of the first insulating head 2. When the guide blocks 5 are fully inserted into the guide grooves 7, the alignment is complete. At this time, pull out the cross bar 13. After the limiting effect is gone, the two limiting rods 12 will be moved downward by the elastic action of the two connecting springs 11, and pass through the two limiting holes 6 on the second insulating head 3, completing the installation. By setting the rubber sealing pad 4, the sealing performance of the joint connection can be increased to avoid affecting the safety and stability of the power line.
