Abstract

PURPOSE: To release a working pressure securely to obtain a nonreturn state by a method wherein the working pressure is expanded in two stages during the detecting operations.
CONSTITUTION: When the pressure governing valve of a pressure cooker gets trouble and the pressure reaches the working pressure of a safety valve, steam comes from a valve hole 5 into a chamber 13. Said steam pushes a seal 11 and is filled quickly in the chamber 13 keeping a hermetic seal thereof. This pressure simultaneously breaks the balance with an energizing force F by a force corresponding to the pressure on a diameter B and the valve body 9 rises. Then, the valve body 9 interrupts a parallel movement by means of a projection 7, is upset and does not return to the original state.
