11.4.1.1 Safety opening device (11)
This Safety device is a 3/2 operating pneumatic spring-loaded valve (2
position, 3 ports) that is connected to the safety port of the door. An
angular bracket (12), which is attached to one of the arms, will push the
valve’s piston to a position that at the instant that the arms are locked,
the safety port of the door is blocked.
At the instant that the arms move backward the valve changes its
position and the chamber is vented. After the pressure in the chamber
equalizes the ambient pressure the autoclave’s door can be opened
with no risk for the operator, of steam or hot water burst.
