The present invention relates to a safety valve device and, more specifically, to a safety valve device which minimizes malfunction and an error rate by using a non-contact solenoid method; improves hermeticity and durability and significantly reduces noise; and facilitates manual operation. The safety valve device according to the present invention comprises a pressing bar on the internal top of a housing to be joined to a spring by the bottom; an elevation housing which is joined to the outer circumferential bottom of the pressing bar and which comprises an outer body and an inner body; a coil body inside aΠ-shaped bracket; a fixed cylindrical body joined to the outer circumferential bottom of the housing to maintain hermiticity; a pressing rod protruding outwards and lengthwise from the through-hole of the housing; a connection body with an inlet and an outlet on both sides to connect them through a pipe conduit to allow a gas to flow; and an opening and closing unit at the bottom of the pressing rod to open or close the pipe conduit of the connection body. The opening and closing unit comprises an opening and closing member integrated with an engagement extension piece; a joint member having a joint protrusion; and an elastic member to pressurize the opening and closing member upwards. Sealing protrusions are integrated with both upper side of the opening and closing member at a distance from each other to prevent the opening and closing member from rising at a predetermined level. |
