Torque limiting device, the outer wall of thread bush is provided with ratchet portion, and what thread bush was screwed onto the packing box body is external to its mouth
At edge, pressure cap is screwed onto thread bush place suitable for reading and applies pressure to the packing by clamping sleeve, and rotary sleeve is to be fixed on screw thread
The ratchet portion of set and can ring its rotate ring bodies, through hole is provided with the wall of rotary sleeve side and pellet sleeve pipe is provided with the through hole,
Briquetting pellet, spring and cock are successively set on from inside to outside in pellet sleeve pipe, and briquetting pellet front end is provided with the spine with thread bush
The ratchet part that wheel portion coordinates, cock is screwed onto at the collar extension of pellet sleeve pipe, and spring is connected between briquetting pellet and cock, and handle is solid
It is scheduled on rotary sleeve outer wall.
The solution have the advantages that：It has rational in infrastructure, easy to use and the pressure that packing applies accurately is set
Advantage, can adapt to different well mouth of oil well sealings, there is provided scientific and reasonable quantitative sealed rotation torque, energy-conservation can be reached
The purpose of environmental protection.
Description of the drawings
Fig. 1 is the cross section structure diagram of the present invention；
