ABSTRACT:
A probe assembly system for high pressure insertion and retrieval in pressure vessels includes a stuffing box fitting with an integrally formed collet which surrounds a probe or device passing axially therethrough. The collet fingers are externally taper threaded and an internally taper threaded collet lock nut locks and releases the collet with minimal rotation. The interior of the collet fingers have teeth which bite into the shank of the probe or device. A single acting hand pump operated tool is quickly attached to the fitting. The tool includes a piston and cylinder with an elastic cord spring return inside the cylinder and attached to the piston in sling shot fashion. The lower end of the tool includes a socket for the collet lock nut which can be tightened and released by axial rotation of the tool. The lower end also includes a window and piston stop. The piston can be attached to the probe, if required. The hand pump includes a pressure gauge and variable relief valve. The entire system is portable and may be operated by one person.
