Intelligent safe switching-off device

The invention discloses an intelligent safe switching-off device. The intelligent safe switching-off device comprises a manual control module, an air cylinder control module and a body assembly module, wherein the manual control module is connected to an intelligent control module which is connected to a motor energy storage module; the air cylinder control module is connected to a locking controlmodule; and a valve position indicator is arranged above the body assembly module. The intelligent safe switching-off device has the beneficial effects that when the pipeline pressure is abnormal, the intelligent safe switching-off device emergently switches off a gas transmission pipeline; a valve uses pipeline natural gas as main power, so that the functions of long-distance high-pressure opening and closing and emergent high-low pressure switching-off can be realized; compared with traditional mechanical self-operated, nitrogen-enabled type and leading role type emergency switching-off structures, the intelligent
