EWO安全阀351系列选型及介绍

Safety valves serve to blow out non-poisonous and non-flammable gases into the atmosphere in order to protect pressure tanks against overpressure.

Please note: Only safety valves that have been set and sealed with lead (plumbed) by us can be delivered with the component symbols, it is thus absolutely necessary to indicate the setting pressure in bar when placing your order. To test their proper functioning, safety valves can be relieved by turning the knurled (thumb) screw to the left. The bearing surfaces and conical seals can be cleaned of impurities by unscrewing the entire upper part - without changing the pressure setting.

安全阀用于将无毒和不易燃气体排入大气，以保护压力罐免受超压。

请注意：仅提供由我们设置并用铅（铅）密封的安全阀及组件符号，因此绝对有必要在订购时以巴表示设定压力。为了测试其正常功能，可以通过向左转动滚花（拇指）螺钉来释放安全阀。拧开整个上部，可以清除轴承表面和圆锥形密封件上的杂质，而无需更改压力设置。只能由制造商进行维修。
