グの保護機構。[Claims for Utility Model Registration] (1) A piston that is pressed in one direction by the biasing force of a pressing spring is fixed to a piston rod with a fixing ring, and the outer surface of this fixing ring is fixed at an appropriate non-pressing interval by a covering protector. What is claimed is: 1. A protection mechanism for a fixing ring, characterized in that it is covered with a piston and a covering protector is pressed against a piston by a biasing force of a pressing spring. (2) A protection mechanism for a fixing ring according to claim 1 of the utility model registration, characterized in that the cover protector is formed into a U-shaped cross section and has one end of the piston rod passed through the center thereof. (3) A protection mechanism for a fixing ring according to claim 1, wherein the covering protector is formed into a U-shape in cross section and covers one end of the piston rod as well as the fixing ring. (4) The fixing ring is used to fix the piston to the piston rod of the air-operated valve. ,
A valve part installed in the piston changes the fluid flow path from normally open to normally closed by sensing an open/close signal and applying control fluid pressure to the piston. A protection mechanism for a fixing ring according to claim 1, which is characterized in that it is in a closed state or in an open state from a normally closed state. (5) The securing ring protection mechanism according to claim 4, wherein the cylinder of the air-operated valve is rotatable relative to the main body. (6) The locking ring protection mechanism according to claim 5, wherein the cylinder is rotatably fixed to the main body via a lock ring.
