mso-hansi-font-family:"Times New Roman"">三. "Times New Roman"">概述
mso-hansi-font-family:"Times New Roman"">安全阀是锅炉、压力容器和其他受压力设备上重要的安全附件。其动作可靠性和性能好坏直接关系到设备和人身的安全，并与节能和环境保护紧密相关。而有的用户和设计部门在选型时，总是选错型号。为此本文对安全阀的选用加以分析。
mso-hansi-font-family:"Times New Roman"">四. "Times New Roman"">作用
mso-hansi-font-family:"Times New Roman"">安全阀在系统中起安全保护作用。当系统压力超过规定值时，安全阀打开，将系统中的一部分气体/ mso-hansi-font-family:"Times New Roman"">流体排入大气/ "Times New Roman"">管道外，使系统压力不超过允许值，从而保证系统不因压力过高而发生事故。上海贯高阀门有限公司
