衬氟蜗轮法兰球阀

概述:

衬氟蜗轮法兰球阀是一种集 “氟塑料衬里耐蚀”“法兰连接稳固”“蜗轮传动省力” 三大特性于一体的球阀,通过阀体内部衬氟层隔绝腐蚀介质、法兰与管道刚性连接、蜗轮机构降低启闭扭矩,核心功能是在强腐蚀工况下实现介质的精准截断与调节,广泛应用于化工、制药、冶金等需耐蚀且大口径 / 高扭矩操作的场景。


公称通径:DN15~DN400

公称压力:PN0.6~PN2.5MPa

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 + 省力 + 稳固)

1、极致耐蚀:全衬氟设计(阀体、球体、密封座均衬 PTFE),解决普通金属球阀在强酸强碱中易腐蚀的问题,使用寿命是不锈钢球阀的 3~5 倍;

2、操作省力:蜗轮传动大幅降低扭矩,手动即可操作 DN400 大口径球阀,无需额外动力(相比电动球阀成本更低);

3、密封可靠:PTFE 密封面具有弹性和自润滑性,双向密封设计(固定球)可适应正反流向,泄漏率低,且耐磨损(球体抛光减少摩擦);

4、连接稳固:法兰连接(符合 GB/T 9113 或 ANSI B16.5)与管道刚性连接,抗振动、抗压力波动,适用于工业管路长期运行。

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.
