在厂矿企业中,氧气表(带高、低压两个表头)主要用来气焊或气割。高压表用来指示氧气瓶中所剩氧气的压力数,低压表的压力数是根据需要来调节焊枪的需氧量。其整套的作用正如它的全称“氧气减压器”一样是一个减压的仪器。 实际.工作中,绝大多数企业或县市计量部门将生产工艺过程 In factories and mines, oxygen meter (with high and low pressure two header) is mainly used for gas welding or gas cutting. The high pressure gauge is used to indicate the pressure of the remaining oxygen in the oxygen cylinder. The pressure of the low pressure gauge is used to adjust the oxygen demand of the welding gun as needed. Its entire set of functions, like its full name “Oxygen Regulator,” is a decompression device. In practice, the vast majority of enterprises or counties and cities will measure the production process
