Quenching chamber with an integral access door

摘要

A quenching apparatus is disclosed which has a generally cylindrical base and upper housing. A removable cover is affixed to the top of the upper housing. The quenching apparatus includes means for supporting the removable cover above the upper housing such that a passageway is defined between the upper housing and the removable cover. A generally cylindrical door is dimensioned and positioned within the quenching apparatus to be coaxial within the upper housing and the base. An actuator is coupled to the cylindrical door for moving the door between an open position and a closed position. In this manner, the door is adapted for closing the opening between the base and the upper housing and thereby provides a closed quenching chamber. Redundant retractable seals are provided in the base and the upper housing to seal the door to the upper housing and the base when the door is closed.
