统一安装燃气阀门系骗局
“我们是燃气公司的，按规定将你家的液化气阀门更换为安全阀门。”五一前，几个自称是燃气公司的人在襄阳路附近的居民区向住户推销“安全阀门”。昨日，记者从该处所属的东风燃气公司得到证实，该公司从未向市民推销过安全阀门，请广大用户谨防上当。 昨日下午，记者就此咨询了东风燃气公司。工作人员表示没有委托任何人上门推销产品，如果有什么改造项目会联合物业提前进行宣传，因此张阿姨等人遇到的肯定不是他们燃气公司的工作人员。 　　工作人员介绍，阀门连接处抹洗洁净会冒泡泡，可能是推销人员故意松动了输气管，燃气灶具的火焰颜色也是可以调整的，这些都是惯用的伎俩。他们同时提醒广大用户，遇到类似情况应先拨打东风燃气公司的咨询电话8218474进行核实，对于来历不明的“工作人员”要提高警惕，以免上当受骗。
