Espresso 机器安全阀

浓缩咖啡机上最重要的安全功能之一是炉安全浓缩咖啡机的最后一招

什么需要安全无法正常工作的最新事件之一生在 2009 年的 Sainsbury'sElektra 浓缩咖啡机的炉爆炸的地方。安装了一种新型安全,但无法正常工作

典型的浓缩咖啡机炉装有水并用加元件加。看到它是一个封炉,炉内部的力和温度都会增加。通常元件由力开关控制,当炉内的力达到一定力开关将切断加元件的源。一旦力下降,加元件将再次开始打开。

但是力开关有可能生故障,所以在您遇到了加元件的源不再关的情况。并将持热锅炉内的水,并增加炉内的蒸汽力。

在某些情况下,安装了炉恒温器或加元件恒温器。将在达到预设温度并需要手重置闭电源。

但是,如果恒温器不存在或出故障,安全将在预设压力下打开,并将过压释放出浓缩咖啡机。这样可以防止炉爆炸。

安全如何工作?

安全本身有一个黄铜阀体,内外都有螺该阀门内部有 4 件(注意,可能因型号和品牌而异)。第一是黄铜垫圈支架,里面有圈。该垫圈通常密封炉以防止蒸汽逸出。该垫圈支架通过锥簧支架固定到位。在此之上,您会发现一个不锈钢压缩弹簧。最后,了保持一切就位,您将有一个黄固定螺阀门的开启力是工厂预设的。当您需要高开启,固定螺向内旋入。当您想要低的开启,它被到外面。

浓缩咖啡机有哪些型的安全

安全有多种配置。如螺纹类型、密封材料、力、阀门材料、认证型、可测试西。

纹类型:

在大多数浓缩咖啡机安全上,它是外螺。最准的螺纹类型是 3/8” BSP-G,但您也可以在各种品牌上找到 ½” BSP-G ¼”BSP-G。有一些品牌也使用公制螺,例如 La San MarcoGaggia Pavoni

校准

用于浓缩咖啡机的炉安全通常 1.8 bar。但也取决于它所使用的浓缩咖啡机的品牌。它的范 1,5 bar 一直到 2,1 bar。当些安全过认证时,它在某种程度上是固定的,无法整。例如,是通盖板或/密封件完成的,因此它无法更改。

认证

有些型号的安全没有认证。使用些型号,您可以整开启力。但大多数型号都通 CEPED 或汽车认证

密封材料

于安全,可以在安全内部使用各种型的密封件。可以是 nbrfkm、硅脂和 PTFE浓缩咖啡机,您通常会发现 Viton 密封件。

测试安全

在某些情况下,您会发现锅炉安全阀顶部有一个。当你拉环时,你会拉一个打开阀门。通此程序,您可以测试密封材料是否没有粘在配合面上。

密封安全

安全可用各种密封材料密封。在大多数情况下,使用可碎的铜垫圈。但在该领域中,您也确看到了 PTFE 或液体密封材料的使用。

替代品

您需要多久更一次炉安全?您应该 2 年更一次。炉安全是一种相便宜的品,如果生故障可能会生很大的后果。
