一、DA21Y、DA42Y低温安全阀产品描述
DADA21Y、DA42Y低温安全阀是在一种用于低温的安全设备,低温安全阀需要通过低温处理,低温处理就是通过低温打压,一般最低温度能够承受零-80°作用,低于这个范围会由于温度太低,承受不了阀门断裂,所以我们要以最低的温度来衡量,一般都是用于氮气、二氧化碳等气体,DA21Y低温安全阀都是由不锈钢材质构成,不锈钢材质在承受低温性能上有优势。DA42Y低温安全阀无需借助任何外力来进行启闭的一种阀门,通过我们设定的整定压力值,当压力超过我们的整定压力值后,DA21Y低温安全阀安全阀会自动开启,释放压力,释放带整定压力以下的时候,安全阀会自动关闭。弹簧式安全阀它是一种利用弹簧的弹性,来对压力进行控制的一种保护管道安全的阀门,弹簧式安全阀也是我们一种常用性的安全阀,具有轻便、结构简单、拆装方便
