Function:
Due to the high pressure inside the gas cylinder, while the pressure required for gas welding, gas cutting, and usage points is relatively low, it is necessary to use a pressure reducer to reduce the high pressure gas stored in the gas cylinder to low-pressure gas, and ensure that the required working pressure remains stable from beginning to end. In short, a pressure reducer is a regulating device that reduces high-pressure gas to low-pressure gas and maintains stable output gas pressure and flow rate.

Classification:

Carbon dioxide pressure reducerAccording to different purposes, it can be divided into oxygen pressure reducers and acetylene pressure reducers, and can also be divided into centralized and post type; According to different constructions, it can be divided into single-stage and two-stage types; According to different working principles, it can be divided into two types: positive action type and negative action type. At present, the common types of domestically produced pressure reducers are single-stage reaction type and two-stage hybrid type (with the first stage being positive acting and the second stage being negative acting).
