管道系统接头泄漏密封性测试仪常见问题

 

一、标准与适用范围

 

Q1:该设备依据什么标准?

设备符合ISO 4422-2:1996ISO 13844:2000DIN EN 1277及对应中国国家标准GB/T 39383-2020《埋地用无压热塑性塑料管道系统 弹性密封圈接头的密封性能试验方法》的要求。

 

Q2:适用于哪些管道系统?

适用于埋地用无压热塑性塑料管道系统中弹性密封圈类型接头的密封性能测定,包括PVC-U单承口、双承口及管件承口等。

 

Q3:试验压力有哪些?

标准规定三种基本试验压力:

- p1:内部负气压(部分真空);

- p2:较低的内部静液压;

- p3:较高的内部静液压。

具体试验压力的选择按相关引用标准的规定执行。

 

 二、试验条件与原理


Q4:试验在哪些条件下进行?

标准规定了以下四种试验条件:

- 条件A:无径向变形和轴向偏角;

- 条件B:有径向变形;

- 条件C:有轴向偏角;

- 条件D:有轴向偏角和径向变形(同时施加)。

试验条件的选择按相关引用标准的规定执行。

 

Q5:试验原理是什么?

PVC-U管段装入待测PVC-U承口组成试样,在规定温度范围内,对试样施加规定的负压(部分真空),同时对管材施加轴向偏角和径向变形,在规定的试验期间内监测接头是否有泄漏迹象。

 

 三、设备功能与特点

 

Q6:设备的主要用途是什么?

本设备用于测定埋地用无压热塑性塑料管道系统中弹性密封圈类型接头的密封性能,验证接头在负压、偏角及变形条件下的气密性。

 

Q7:设备有哪些主要特点?

- 配备液压式径向变形装置,高精度数显仪表显示;

- 可施加四个方向的轴向偏角;

- 试样装夹系统设计独特,安装便捷;

- 测试数据可通过USB接口快速导出至计算机,便于后续分析和报告生成。

 

Q8:设备有哪些型号可选?

设备提供两种型号:适用于管径不超过500 mm的型号专为小直径管材测试设计,适用于600 mm及以上管径的型号用于大直径管材测试,均确保操作便捷高效。
