摘要
研制了遇热自动关闭安全阀,该阀在使用时可方便地串接在燃气管道上,利用双金属片制成的温控片遇热形变的微小变化,通过触发机构触发弹簧力驱动阀芯,在当环境温度或者管道内气体温度达到设定的警戒温度时,自动切断燃气,有效地避免或减少了灾害和损失,同时其不用电,体积小巧,结构简单、安全可靠,值得大力推广。
The development of the heat automatically shut off the safety valve, the valve can be conveniently connected in series on the gas pipeline in use, temperature control sheet using double metal sheet made of tiny change in hot deformation, the trigger mechanism drives the valve core to trigger the spring force, when the gas temperature or pipe temperature reaches the set warning temperature, automatically cut off the gas, effectively avoid or reduce the disasters and loss, at the same time, without electricity, small volume, simple structure, reliable and safe, is worth popularizing.
