三、壳体试验和密封试验:

1、插板阀的壳体试验和密封试验介质为水(含防腐剂)、煤油或粘度不大于水的其他适宜液体。
2、密封副是非金属密封的插板阀,密封壳体试验和要求按GB/T13927-92 D级规定。
3、密封副是金属密封的插板阀,对有密封性能要求的,密封试验的泄漏量按1×DNmm3/s计算,没有密封性能要求的不做
  此项试验。
4、用电动、液动、气动装置驱动的插板阀,关闭位置调定后,关闭3次按1和3要求进行壳体和密封试验。
5、插板阀清洁度要求按JB/T7748的规定。
6、静压寿命试验。
7、插板阀静压寿命试验次数按规定,其他技术要按JB/Z 234的规定。

静压寿命实验次数

金属密封

DN≤150mm

1200次

DN≥200-400mm

1000次

Dn≤150mm

800次

非金属密封

Dn≤150mm

1400次

DN≤200-400mm

1200次

Dn≤450mm
