Plug for sealing signal line of instrument probe

Abstract

The invention relates to a plug for sealing a signal line of an instrument probe, and belongs to the technical field of petroleum storage and transportation. The plug includes a plug seat having a through cavity and a plug gland attached to one end of the plug seat for sealing the through cavity, the plug gland comprising a gland body and a sealing gasket between the plug seat and the gland. A wire bolt is disposed on the sealing gasket, one terminal of the wire bolt is located in the through cavity, and the other terminal of the wire bolt is located outside of the gland body. The plug provided by the embodiment of the invention solves the problem of poor sealing effect caused by a signal line of an instrument probe directly passing through a sealing pad, and the lubricating oil can be completely sealed to ensure that the oil and gas are not leaked; waste of lubricating oil is avoided, the safety hazard of erosion of electronic components by lubricating oil and lubricant leakage is eliminated.

Description

technical field [0001] The invention relates to the technical field of oil storage and transportation, in particular to a plug used for sealing instrument probe signal lines. Background technique [0002] The compressor is the core equipment of the natural gas transportation pipeline. The rotation speed of the compressor is generally high-speed rotation, and the general rotation speed is 4500r / min-5500r / min. Such high-speed rotation equipment must lubricate the bearings, and at the same time, the temperature of the bearings needs to be detected online. To master the operation of the compressor. [0003] When the existing temperature probe signal lead wire enters and leaves the bearing box wall, there is an oil leakage problem in the plug of the compressor temperature probe signal lead wire. When the compressor is running, the temperature of the lubricating oil is relatively high, generally around 60°C-70°C, and oil and gas are generated in the bearing box. The existing comp...

AI Technical Summary

Problems solved by technology

Rubber ring 1' is bound to cause damage and failure after being squeezed for a long time and under a large temperature difference, thus losing the sealing function, and it is difficult to achieve long-term complete sealing

Oil and gas leak from the sealing gap, enter the junction box, pass through the lead pipe, and finally enter the compressor control box, affecting the control components, causing waste of lubricating oil, polluting the environment, and posing safety hazards
