Pipe gallery butterfly valve

^{管廊蝶閥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‌
‌橡膠密封‌：適合常規(guī)介質(zhì)，低壓密封性能優(yōu)異。
‌金屬硬密封‌：耐高溫高壓（Class600–1500），三偏心結(jié)構(gòu)減少磨損，可替代閘閥。
三、選型與維護要點
‌關(guān)鍵因素‌ ‌要求‌
‌密封類型‌ 腐蝕性介質(zhì)選金屬密封；常規(guī)介質(zhì)用橡膠密封
‌連接方式‌ 對夾式（空間極受限）、法蘭式（檢修便利）
‌操作機構(gòu)‌ 大口徑需配蝸輪減速器或電動執(zhí)行器
‌維護重點‌ 定期檢查密封件老化、閥桿潤滑、避免<15°小開度長期使用
四、典型應(yīng)用場景
‌市政管廊‌：給排水、消防管道的主控閥門。
‌工業(yè)管廊‌：石油化工的腐蝕性介質(zhì)輸送、電力管網(wǎng)蒸汽調(diào)控。
‌特殊環(huán)境‌：放射性介質(zhì)隔離、泥漿管路節(jié)流。
管廊蝶閥憑借其結(jié)構(gòu)適應(yīng)性、操作效率及密封可靠性，已成為地下管網(wǎng)系統(tǒng)的關(guān)鍵控制部件。
