Description

Technical Field

[0001] The utility model mainly relates to the field of precision valve production, and in particular to a torque locking device used for precision valves. Background Art

[0002] Precision valve is a device used in water, steam, air and other media pipelines. Its main function is to control the flow of the medium by adjusting the opening of the opening and closing parts in the valve body, and at the same time adjust the opening of the opening and closing parts with the help of the pressure behind the valve to keep the pressure behind the valve within a certain range. This valve can keep the outlet pressure within the set range when the inlet pressure is constantly changing, thereby protecting the subsequent life and production equipment;

[0003] After the precision valve is produced, the hexagon socket bolts of the precision valve need to be tightened using a torque locking device.

[0004] The inventor discovered the following defects during the operation of the specific embodiment:

[0005] However, when the hexagon socket bolts of the precision valve are directly tightened manually, if too much force is used, the internal threads of the precision valve may be easily damaged. If too little force is used, the hexagon socket bolts cannot be in close contact with the precision valve, causing the sealing effect of the precision valve to decrease and the medium to easily flow out through the gap.
