Claims

[Claims for Utility Model Registration] (1) An automatic air vent valve connected to the middle of an exhaust pipe of a high-pressure steam sterilizer, the automatic air vent valve having an exhaust hole on its top surface and an intake hole on its side surface. , a main body case whose lower surface is open, a bellows valve that opens and closes the exhaust hole by the action of a bellows that expands and contracts in the axial direction of the main case according to temperature changes, and a bellows valve that is installed inside the main case. An automatic air vent valve for a high-pressure steam sterilizer, comprising a bellows seat detachably attached to the open end of the supported main body case and movable in the axial direction of the main body case. (2) The bellows valve is inserted into the main body case by inserting its upwardly and downwardly protruding protrusions into the exhaust hole formed in the upper surface of the main body case and the recess formed in the bellows seat. Utility model registration claim No. 1 characterized in that it is supported by
Automatic air vent valve for high-pressure steam sterilizers as described in ). (3) Utility model registration claim No. (2), characterized in that the bellows valve has a downwardly projecting protrusion that is removably fixedly supported in a recess formed in the bellows seat. Automatic air vent valve for high-pressure steam sterilizers as described in section.
