Description

Technical Field

[0001] This utility model relates to the field of voltage regulator technology, specifically to a venting sleeve that can autonomously vent the voltage regulator. Background Technology

[0002] During routine maintenance and safety inspections of the RB-type pressure regulating box, a slight leak was found at the top cover of the pressure regulator. This is because when the outlet pressure of the pressure regulating box exceeds the set value of the venting pressure, the pressure regulator will release a small amount of pressure through the venting mechanism. At this time, it is necessary to adjust the pressure regulating venting nut on top of the pressure regulator. However, when adjusting the venting nut, it was discovered that there is also a tightening nut above it, and the space at the top cover of the pressure regulator is too small. Existing sockets and wrenches cannot adjust both nuts simultaneously. Using only one socket would cause the lower venting nut to rotate continuously, potentially damaging the lower pressure regulating spring. If an emergency is not handled promptly and effectively, the impact and losses will inevitably expand, posing a significant threat to the environment and the personal safety and property of surrounding residents.
