Abstract
A gas shutoff device of the present invention is configured such that a control section determines that it inhibits a shutoff section from being returned from a shutoff state to a supply state, when a vibration has been detected by a vibration detecting section and a fluid pressure measured by a pressure measuring section has decreased to a value equal to or less than a predetermined pressure value. For example, the control section causes the shutoff section to switch to the shutoff state and disenables the return section to return the shutoff section to the supply state, when one of the vibration and the fluid pressure decrease has been detected and then the other has been detected within a predetermined time.
Claims15
A fluid shutoff device comprising:
- a shutoff section coupled to a fluid supply pipe and configured to switch from a supply state in which a fluid flows through the fluid supply pipe to a shutoff state in which the fluid is shutoff;
- a control section for controlling at least the shutoff section;
- a flow measuring section for measuring a flow rate of the fluid;
- a pressure measuring section for measuring a pressure of the fluid;
- a vibration detecting section for detecting a vibration;
- and
- a return section for returning the shutoff section from the shutoff state to the supply state;
- wherein when the vibration detecting section has detected the vibration within a preset predetermined time, and it has been detected that the pressure of the fluid measured by the pressure measuring section has decreased to a value equal to or less than a predetermined pressure value within a preset predetermined time, the control section causes the shutoff section to switch to the shutoff state and disenables the return section to return the shutoff section to the supply state.
A non-transitory storage medium that stores a computer program for causing a computer to implement a control section included in a fluid shutoff device, the fluid shutoff device comprising:
- a shutoff section coupled to a fluid supply pipe and configured to switch from a supply state in which a fluid flows through the fluid supply pipe to a shutoff state in which the fluid is shutoff;
- a flow measuring section for measuring a flow rate of the fluid;
- a pressure measuring section for measuring a pressure of the fluid;
- a vibration detecting section for detecting a vibration;
- and
- a return section for returning the shutoff section from the shutoff state to the supply state,
- wherein the control section controls at least the shutoff section in such a manner that when the vibration detecting section has detected the vibration within a preset predetermined time, and it has been detected that the pressure of the fluid measured by the pressure measuring section has decreased to a value equal to or less than a predetermined pressure value within a preset predetermined time, the control section causes the shutoff section to switch to the shutoff state and disenables the return section to return the shutoff section to the supply state.
