Abstract

PURPOSE: To prevent gas from leaking out by means that after an emergency has passed and an original action is reset, a communication hole remains closed by an equalizing valve until difference in pressure between upstream and downstream fluid comes down to a specified value or less.
CONSTITUTION: When an emergency signal turns off a control switch to de-energize an electromagnetic coil, a spring 4 is released to down a plunger 3, which pushes a sub-valve 2 to make contact with an equalizing plate 10. Then the plate colse an equalizing hole 10. The equalizing plate 10 makes further down against a spring 11 until a main valve 9 closes a communication hole 7. Under the state, an emergency is released. After that, if the control switch is turned on to energize the electromagnetic coil 18, the magnetic force is too weak to attract the plunger 3. the communication hole 7 remains closed. Even if a pushbutton 14 is depressed to manage the plunger 3 to be attracted on the coil, gas released from the valve opened under load pushes the equalizing plate 10 to remain closed.
