Technical requirements of Gaizhou rx680/0.4c-rf double run run gas regulator
In the process of gas transportation and distribution, gas pressure regulation is an essential part. As we all know, the basic task of the regulator is to adjust the higher inlet pressure of the front stage to the pressure needed downstream, and to resist the disturbance of fluctuating inlet pressure and flow change, so as to maintain the outlet pressure as a constant value. City gas has a history of over 100 years in the world. With the development of the gas industry, the pressure regulating equipment is also constantly upgrading. As far as gas regulator itself is concerned, it is not the same as before in terms of regulation stability, wide use, manufacturing process, design versatility and even operation safety and reliability. In order to operate safely, economically and reliably, people usually install the equipments with the functions of pressure regulation, flow measurement and safety protection in the same room, i.e. gas pressure regulating station, or assemble gas pressure regulating box. 　　
In the operation of gas, ensuring safety is always the most important factor. In the final analysis, the safety and normal operation of gas regulator stations is closely related to the lives and property of millions of households. Once the gas leakage or overpressure occurs, the consequences will be disastrous. Therefore, it is necessary to equip a complete set of safety devices in the normal operation of the surge station. Its significance lies in that under any accident, the gas source can be automatically cut off at the first time or the overpressure gas can be discharged to the atmosphere to protect the safety of downstream pipeline users.
