城市门站

　　概述该系列调压站通常采用撬装式结构.是天然气长输管线进入城市管网的关键 设备.主要适用于天然气长输管线的分输线站、首站的下游或者城市的中压管网的上游作为城市门站。燃气管网的配气站、CNG站等高-高、高-中压 燃气管网的调压和稳压：具有净化、计量、调压、分配。安全保护等功能.. 还可根据用户要求配置燃气报警系统.自控系统，加臭系统。也可以选装 RTU单元和通讯单元。
　　OverviewThis series of pressure regulating stations is usually skid-mounted. Served as the key of supporting the gas long-distance transmission pipeline into the city pipe network, the equipment mainly applies to the branch station of the gas long-distance transmission pipeline as well as the downstream of the first station or the upstream of the city medium pressure network as the city gate station. The pressure regulation and stabilization of the high-high and high-medium pressure gas networks of the gas distribution station, CNG station, etc. of the gas networks have functions such as purification, metering, pressure regulation, distribution and safety protection. The equipment can also be configured with gas alarm system, automatic control system and odorization system according to the user’ s requirements, and can also be configured with optional RTU unit and communication unit.
