管道系統接頭泄漏密封性測試儀常見問題

 

一、標準與適用範圍

 

Q1:該設備依據什麼標準?

設備符合ISO 4422-2:1996、ISO 13844:2000、DIN EN 1277及對應中國國家標準GB/T 39383-2020《埋地用無壓熱塑性塑料管道系統 彈性密封圈接頭的密封性能試驗方法》的要求。

 

Q2:適用於哪些管道系統?

適用於埋地用無壓熱塑性塑料管道系統中彈性密封圈類型接頭的密封性能測定,包括PVC-U單承口、雙承口及管件承口等。

  

Q3:試驗壓力有哪些?

標準規定三種基本試驗壓力:

- p1:內部負氣壓(部分真空);

- p2:較低的內部靜液壓;

- p3:較高的內部靜液壓。

具體試驗壓力的選擇按相關引用標準的規定執行。

 

 二、試驗條件與原理

 

Q4:試驗在哪些條件下進行?

標準規定了以下四種試驗條件:

- 條件A:無徑向變形和軸向偏角;

- 條件B:有徑向變形;

- 條件C:有軸向偏角;

- 條件D:有軸向偏角和徑向變形(同時施加)。

試驗條件的選擇按相關引用標準的規定執行。

 

Q5:試驗原理是什麼?

將PVC-U管段裝入待測PVC-U承口組成試樣,在規定溫度範圍內,對試樣施加規定的負壓(部分真空),同時對管材施加軸向偏角和徑向變形,在規定的試驗期間內監測接頭是否有洩漏跡象。

 

 三、設備功能與特點

 

Q6:設備的主要用途是什麼?

本設備用於測定埋地用無壓熱塑性塑料管道系統中彈性密封圈類型接頭的密封性能,驗證接頭在負壓、偏角及變形條件下的氣密性。

 

Q7:設備有哪些主要特點?

- 配備液壓式徑向變形裝置,高精度數顯儀錶顯示;

- 可施加四個方向的軸向偏角;

- 試樣裝夾系統設計獨特,安裝便捷;

- 測試數據可透過USB介面快速導出至計算機,便於後續分析和報告生成。

 

Q8:設備有哪些型號可選?

設備提供兩種型號:適用於管徑不超過500 mm的型號專為小直徑管材測試設計,適用於600 mm及以上管徑的型號用於大直徑管材測試,均確保操作便捷高效。
