ABSTRACT:
This invention relates to an improved high pressure mounting for removably positioning pitot tube type flow measurement devices in a pipeline where the mounting includes a hollow tubular collar welded to the pipe in alignment with a probe-receiving opening therein and which is sized to slidably receive the body of the probe for movement into and out of the pipe, a relatively deformable and compressible ferrule encircling the probe body movable into abutting relation to an annular seat provided on the end of the collar remote from the welded end thereof, and a compression nut adapted to be screwed onto a threaded end of the collar adjacent the seat and cooperate therewith and with the ferrule therebetween to crimp the latter tightly around the probe thus sealing the probe in a fixed operative position, the improved positive lock which is characterized by adding an externally-threaded male extension to the compression nut, providing the probe body with a fixed abutment-forming projection exposed beyond said extension, and mounting a hollow open-ended generally cup-shaped cap on the probe body on the opposite side of the projection from the extension, the projection being sized to pass easily into the cap while the latter has both an internally-threaded portion adapted to screw onto the extension as well as an abutment-forming shoulder positioned and adapted to engage the projection when thus threadedly interconnected thereby preventing the probe body from being withdrawn from the collar.
