摘　　要：针对现有调压站运行中的问题,提出一种燃气智能调压技术。该技术在指挥器前后分别增加微流阀和导阀,利用可编程逻辑控制器对工艺数据进行逻辑控制,通过电气转换器控制微流阀,由微流阀驱动指挥器和导阀,实现压力调节、支路均衡供气、分时压力调节。结合工程实例,验证该技术的良好效果。Aiming at the problems in the operation of existing pressure regulating stations,an intelligent gas pressure regulating technology is proposed.This technology adds micro-flow valve and pilot valve before and after the pilot respectively.The programmable logic controller is used to logically control the process data.The micro-flow valve is controlled by an electrical converter.The micro-flow valve drives the director and pilot valve to achieve pressure regulation,branch balanced gas supply,and time-sharing pressure regulation.Combined with engineering examples,the good effect of this technology is verified.
