标准摘要
[中文适用范围]: 本国际标准规定了由热塑性材料制成的止回阀的设计、功能特性和制造要求,旨在允许液体流体仅沿一个方向流过阀门并防止回流、止回阀与管道系统的连接、阀体材料其压力/温度额定值介于 - 40 °C 和 + 120 °C 之间,使用寿命为 25 年,并指定了其测试。 本国际标准适用于安装在工业管道系统中的阀门,无论应用领域和输送的流体如何。 注 1:工业管道系统还包括一般用途的供水系统、排水系统和污水处理系统。 注 2:特殊要求可适用于人类消费水的管道系统。 本国际标准涉及DN DN 8、DN 10、DN 15、DN 20、DN 25、DN 40、DN 50、DN 65、DN 80、DN 100、DN 125、DN 150、DN 200、DN的范围250、DN 300、DN 350、DN 400、DN 500 和 DN 600 以及 PN 和 PN 6 级、PN 10、PN 16、PN 25 以及 150 级和 300 级范围。 [外文原描述]: ISO 16137:2006 specifies requirements for the design, functional characteristics and manufacture of check valves made of thermoplastics materials intended to allow the flow of liquid fluids through the valve in one direction only and to prevent backflow, their connection to the pipe system, the body materials and their pressure/temperature rating between -40 degrees Celsius and + 120 degrees Celsius, for a lifetime of 25 years, and also specifies their tests. ISO 16137:2006 is applicable to valves to be installed in industrial pipe systems, irrespective of the field of application and the fluids to be conveyed. It is concerned with the range of DN 8, DN 10, DN 15, DN 20, DN 25, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200, DN 250, DN 300, DN 350, DN 400, DN 500 and DN 600, and the range of PN 6, PN 10, PN 16, PN 25, and Class 150 and Class 300.
