Pipe gallery butterfly valve

^{管廊蝶阀is a high-performance butterfly valve designed specifically for comprehensive pipe galleries (underground pipeline centralized laying systems). Its main functions and application advantages are as follows:}

^{1、 Core functions
Fluid cutting and throttling
The pipe gallery butterfly valve controls the on/off of the pipeline medium (liquid/gas) by rotating the disc-shaped butterfly plate. When the butterfly plate is parallel to the fluid direction, it is fully open; when it is perpendicular, it is fully closed; Adjusting to an angle of 15 ° -70 ° can achieve precise flow control.
Wide adaptability to media
Suitable for water, steam, oil, corrosive liquids, mud, and even radioactive media, thanks to the elastic design of rubber or metal sealing rings.
2、 Advantages of Pipe Gallery Application
Space efficiency
Compact structure, light weight, short axial length, greatly saving limited space in the pipe gallery.
Quick opening and closing with low maintenance
Rotate 90 ° to complete the switch and respond quickly; The replacement cycle of elastic sealing rings is short (1-2 years), and the service life of metal seals can reach several decades.}

‌密封可靠性‌
‌橡胶密封‌：适合常规介质，低压密封性能优异。
‌金属硬密封‌：耐高温高压（Class600–1500），三偏心结构减少磨损，可替代闸阀。
三、选型与维护要点
‌关键因素‌ ‌要求‌
‌密封类型‌ 腐蚀性介质选金属密封；常规介质用橡胶密封
‌连接方式‌ 对夹式（空间极受限）、法兰式（检修便利）
‌操作机构‌ 大口径需配蜗轮减速器或电动执行器
‌维护重点‌ 定期检查密封件老化、阀杆润滑、避免<15°小开度长期使用
四、典型应用场景
‌市政管廊‌：给排水、消防管道的主控阀门。
‌工业管廊‌：石油化工的腐蚀性介质输送、电力管网蒸汽调控。
‌特殊环境‌：放射性介质隔离、泥浆管路节流。
管廊蝶阀凭借其结构适应性、操作效率及密封可靠性，已成为地下管网系统的关键控制部件。
