United Pressure Regulator

United Pressure Regulator

Gas working principle: The high pressure natural gas in the sump tank is preheated and step by step, and the safety control and metering, odor and other processes are carried out so that the gas pressure reaches the pressure required to meet the specifications. According to the regulator mechanism can be divided into two levels of pressure regulator and three pressure regulator. Brief Introduction of CNG United pressure regulator Structure

Brief Introduction of CNG United pressure regulator

  Gas working principle: The high pressure natural gas in the sump tank is preheated and step by step, and the safety control and metering, odor and other processes are carried out so that the gas pressure reaches the pressure required to meet the specifications. According to the regulator mechanism can be divided into two levels of pressure regulator and three pressure regulator. Brief Introduction of CNG United pressure regulator Structure

Compressed natural gas decompression regulator in accordance with the equipment and the layout of the regulator and the equipment is divided into:

   Unloading system (high pressure hose, quick connector, high pressure valve); pressure regulating heat transfer system (high pressure emergency shutoff valve, heat ex-changer.

Flow metering system (flow meter) control system (central console); heating system (gas boilers, hot water pumps, etc.).

  First of all, the high-pressure natural gas through the dump truck system into the pressure transfer heat transfer system, in the regulator heat transfer system after two heat transfer, two or three times into the flow measurement and odor system, and then enter the pipe network. The heating system provides the heat required for the gas decompression process, and the control system monitors the entire system. Differences between Regulating Natural Gas Regulating System and Pipeline Pressure Regulating System

  Compressed natural gas pressure of 22MPa is ultra-high pressure gas, compared with the pipeline regulator on the safety requirements of the equipment more demanding.

  Compression of natural gas decompression process because the reduction of the magnitude of the gas will cause a rapid decline in the temperature, so the process of compressed natural gas need to add heat to the gas.

  Compressed natural gas decompression process is a gradual reduction in the pressure of the process, the import pressure will be reduced with the gas inside the pry, the pressure gradually reduced from 22MPa to 0.5-1.0MPa, so the scope of application of equipment pressure requirements higher.

  Compressed natural gas pressure is higher than the pipeline natural gas pressure, generally through two or three pressure regulator in order to make the final pressure to reach the pressure into the pipe network.
