机械式燃气温控阀的典型流量温度曲线与结构

Typical flow temperature curve and structure of mechanical gas temperature control valve

通过介绍机械式燃气恒温器的流量曲线特点及机械结构,了解关键件对关键参数回差的影响及跳转簧片设计中应注意的问题。需要注意的是,跳转簧机械结构是燃气流量小于15 L/min的小流量机械式燃气阀,对于大流量的阀类似的结构,要考虑簧片的性能和使用寿命问题,可增加杠杆结构缩放力值。

By introducing the flow curve characteristics and mechanical structure of mechanical gas thermostat,the influence of key parts on the hysteresis of key parameters and the problems in the design of jumping reed are discussed.It should be noted that the jump spring mechanical structure is a small flow of gas flow less than 15 L/min mechanical gas valve. It needs to consider the reed performance and service life for large flow of the valve,which can increase the leverage structural scale force.
