The invention discloses a special timer-shut-down valve safety device for a gas stove. The special timer-shut-down valve safety device comprises a box body and a valve body, wherein a section of horn cavity is arranged in a valve cavity of the valve body; a tapered valve plug is arranged in the horn cavity; the tapered valve plug is connected with a valve rod; an elastic sealing valve cover capable of extending and retracting along with shifting of the valve rod is arranged on the valve rod; the elastic sealing valve cover is used for sealing and covering the valve body and a hole gap therein, wherein the hole gap is formed in the valve body after the valve rod passes through the valve body; the free end of the valve rod is hinged with a transmission lever; the other end of the transmission lever is freely hinged with a tension bar; a nose is arranged on the free end of the tension bar; the nose is in engagement and disengagement connection to an engagement and disengagement hook; an electromagnet trigger is arranged near the other end of a engagement and disengagement rod; and the electromagnet trigger is connected with a timer. The special timer-shut-down valve safety device is safe and reliable, is capable of being shut down in a timed manner, and is further capable of normally working under an electric condition or a non-electric condition.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a safety device for timing closing valves dedicated to gas furnaces. Background technique [0002] There are various gas valves in the market, and there are too many to count. No one can know which valve can achieve safe and reliable performance. However, gas accidents are all due to the poor sealing of gas valves, leakage and other safety accidents. . [0003] For example, a gas valve disclosed in utility model patent CN201120152748.5 includes a valve body and a handle, a valve core and a valve stem are arranged in the valve body, one end of the valve stem is connected to the valve core, and a positioning rod is provided between the valve stem and the handle. One end of the positioning rod is fixed circumferentially with the other end of the valve stem, the other end of the positioning rod is connected to the handle, and there is a device between the positioning rod and the valv...
