Description

内出火孔是由内焰挡火圈 2062和内出火圈 2061交替层叠构成的，通过改变每一个交替 层中内焰挡火圈 2062或内出火圈 2061的数量， 比如， 利用多片对齐后的内出火圈 2061和 内焰挡火圈 2062进行交替层叠， 可以增大内出火孔的出火面积， 亦即提高内出火孔的燃烧 功率， 反之可以降低内出火孔的燃烧功率； 同理， 还可以调节外出火孔的燃烧效率， 从而有 效实现燃烧器燃烧功率分布的简便调节。
在使用一些锅底较小的锅子时， 为防止锅底将燃烧器堵死， 在所述上顶盖 202上设有 防止锅底完全封死燃烧器顶部的安全柱 210， 优选的， 所述的安全柱 210设计为能直接套设 在销 201顶部的空心柱体。
所述进气座 209的进气端与主通道管 403连接， 所述的进气座 209上设有挡圈， 所述 主通道管 403上设有的倒角能防止液体渗入进气座 209与主通道管 403的连接缝隙，防止生 锈， 延长使用寿命。
