煤气瓶检测后角阀变成旧的
最近，平远的凌先生遇到一件烦心事：他前段时间拿着家中两个煤气瓶去检测，不料瓶子送回时角阀却被换成另一个，虽然没发生过事故，但凌先生总觉得不安全。 　　凌先生说，他的两个煤气瓶是2006年购买并开始使用的。今年6月中旬，他把瓶子送到平远县中行液化石油气储罐站进行检测。约一个星期过后，瓶子检测完毕后送还，并未发生有异常。“但我发现角阀很旧，不是原来那个。”他说，被换过的角阀用起来有些不习惯，他曾经找过中xx站，但对方答复说这属于检测过程中安装角阀的正常现象，不会有质量和安全问题，至于检测后为什么不安装原来的角阀，具体要问负责检测业务的市富乐钢瓶检测有限责任公司。 　　带着凌先生的疑问，记者咨询了市富乐钢瓶检测有限责任公司负责人林先生。林先生表示，煤气瓶使用的最长年限是15年，每4年须检测一次。通常，各地液化气储罐站运来钢瓶后，他们会将瓶装供气系统退化不合格的角阀、减压阀密封圈、胶管或钢瓶体等进行更换安装。“凌先生被换的角阀，可能会比原来的要旧，但质量是有保障的，使用时也不必担心有安全问题。”林先生说，如果要使角阀等置换过的系统零件变得清洁，可用洗衣粉水洗掉表层的污渍。
