Abstract
Description
Technical Field
[0001] The utility model belongs to the field of voltage regulator maintenance equipment, in particular to a voltage regulating wrench used for a voltage regulator. Background Art
[0002] As a high-quality clean energy, pipeline natural gas has been widely used in industry, commerce, urban and rural residents' lives and other fields. The pressure regulator is an important component on the natural gas pipeline. The pressure regulator needs to turn the adjusting screw when adjusting the gas pressure in the natural gas pipeline. When turning the adjusting screw, you first need to loosen the locking nut counterclockwise, but the adjusting gland and the locking nut are in contact. If the adjusting gland and the locking nut are rusted and adhered, it is easy to turn the adjusting gland and the locking nut at the same time. When turning the adjusting screw, it is also easy to drive the adjusting gland to rotate, causing unnecessary trouble. If you use your other hand to grab the adjusting gland to prevent it from rotating when loosening the locking nut, it is very laborious. For this reason, we have designed a pressure regulating wrench for the pressure regulator. Utility Model Content

The utility model has a simple structure and an ingenious design. The cooperation between the circular ring 5 and the adjusting gland 2 prevents the adjusting gland 2 from rotating when the locking nut 4 and the adjusting screw 3 are loosened. At the same time, the grip 7 is used to increase the force arm to achieve the effect of labor saving. The utility model can meet actual needs and is suitable for promotion. When using the utility model, the circular ring 5 is firstly mounted on the outer periphery of the adjusting gland 2. With the cooperation of several protrusions 6 and the anti-slip patterns on the outer periphery of the adjusting gland 2, the circular ring 5 and the adjusting gland 2 are prevented from rotating relative to each other. Then, the grip 7 is held in one hand, and the locking nut 4 is loosened with a wrench with the other hand, and the adjusting screw is then screwed with the wrench. After use, the circular ring 5 is removed, and the grip 7 is rotated to the inner side of the circular ring 5 to realize the storage of the device.
