MOUNTING DEVICE OF PRESSURE REGULATOR IN PRESSURE VESSEL

PROBLEM TO BE SOLVED: To attach/detach a pressure regulator (pressure reducing valve) easily and quickly for a pressure vessel mounting a cover body for protecting so as to encircle a vessel valve. SOLUTION: A guide support member 12 is installed to an installation nut 11 screwed to the regulator installation port 5 of a vessel valve 3 and supported movably in an axial direction by the guide support member 12 and a seal member 27 is mounted on the tip part of a regulator connection pipe 13 extending after penetrating the center part of the installation nut 11. Further, a pipe shape joint 14 extending to a nearly right angle direction for the axis is connected in a communication state to the rear end of the regulator connection pipe 13 and the pipe shape joint 14 has a connected port 32 connected to the entrance 7 of a pressure regulator 6 and a clamp lever 15 providing a cam means 35 connected in a communication state by pushing the pipe shape joint 14 and contacting the tip of the regulator connection pipe 13 to the regulator installation port 5 through the seal member 27 is pivoted to the guide support member 12.
