衬氟手动法兰蝶阀

概述:

衬氟手动法兰蝶阀是一种结合 “氟塑料衬里强耐蚀”“法兰连接稳固”“手动操作便捷” 三大特性的蝶阀,通过阀体、阀板表面的氟塑料衬里隔绝强腐蚀介质,以法兰与管道刚性连接,借助手动杠杆或手轮驱动阀板旋转实现介质通断与调节,核心应用于化工、制药、环保等强腐蚀工况下的中低压管路系统。


公称通径:DN50~DN600

公称压力:PN0.6~PN1.6MPa

适用温度:-196℃~260℃(PTFE)、-80℃~200℃(FEP)

适用介质:强酸(盐酸、硫酸、硝酸)、强碱(氢氧化钠)、强氧化剂(双氧水)、有机溶剂(甲醇、丙酮)

核心优势(耐蚀 + 便捷 + 经济)

1、全工况耐蚀:阀体、阀板、密封座均采用氟塑料衬里,解决普通金属蝶阀(如不锈钢、铸铁)在强腐蚀介质中易生锈、泄漏的问题,使用寿命可达普通蝶阀的 3~5 倍;

2、操作便捷灵活:手动杠杆 / 蜗轮驱动,小口径快速启闭,大口径省力调节,且可通过手轮精准控制流量,适配 “全开 / 全关” 与 “流量调节” 双重需求;

3、流通阻力小:阀板全开时与流道平行,介质流通截面大,阻力系数(ζ)仅 0.1~0.5(远低于截止阀、闸阀),能耗更低;

4、成本与安装友好:相比同规格衬氟球阀,衬氟蝶阀结构更紧凑、重量更轻(约轻 30%),采购与安装成本更低,且法兰连接适配多数工业管路标准(GB/ANSI/DIN)。

Products and services that meet fluid control requirements

Each process, each facility, and each environmental constraint has its own special requirements. Therefore, Dongyan offers a comprehensive range of products covering different performance levels, pressures, different functions and different materials.

Product Application Scope

These devices are suitable for accurately controlling media such as gases, liquids, steam, etc., and maintaining process parameters such as pressure, flow rate, temperature, and liquid level at given values. Especially suitable for work environments where the allowable pressure difference is small and the allowable leakage is also small, and the pressure difference is not significant.
