Abstract

The utility model relates to a multifunctional self-closing valve. At present, the phenomenon of pipeline fuel gas supply at high pressure easily happens because of inconsistent environments. If a user does not close a valve or a gas cooker valve of a gas appliance in time or forgets to close the same in rush repair, a fuel leakage and an explosion accident can be caused when the fuel gas is supplied again, thereby endangering surrounding persons and social safety. The utility model aims to develop a multifunctional self-closing valve. The multifunctional self-closing valve is characterized in that a valve body is connected with a valve cover; a control lever component and a magnet component are assembled in the valve body; an iron sheet (8) is in socket joint with a boss on the upper part of the control lever (15) which can move up and down; and the iron sheet (8) is in separation or pull-in contact with the upper surface of a center-passing permanent magnet (9). The self-closing valve can not only be automatically closed at the over-pressure or the under-pressure, but also utilize power supply signals of an alarm and a detector to enable a solenoid coil in the valve to generate electromagnetism so as to forcibly close the valve. The multifunctional self-closing valve has the advantages of high practicability, simple structure and high safety.
