Therefore, an energy-efficient natural gas valve is urgently needed to be improved. Content of the Utility Model

It is a high-molecular compound with the function of reducing resistance. When it is added to the fluid during fluid transportation, effects such as increasing the flow rate and reducing the energy consumption can be achieved.
