衬胶法兰截止阀

概述:

衬胶法兰截止阀是一种在阀体、阀盖、阀瓣等与介质接触的关键部位衬覆橡胶(如天然橡胶、丁腈橡胶、氟橡胶等)的法兰连接式截止阀,核心功能是在弱至中等腐蚀、含颗粒或粘性介质工况下实现介质的截断与调节,通过橡胶衬里隔绝腐蚀介质、法兰确保管路稳固连接,广泛应用于化工、水处理、冶金等行业的中低压管路系统。


公称压力:PN0.6~PN1.6MPa

公称通径:DN15~DN300

适用温度:-40℃~200℃

适用介质:弱 / 中等腐蚀性介质(稀酸、稀碱)、含微量颗粒介质(如污水、矿浆)、粘性介质(如润滑油、糖浆)


核心优势(耐弱蚀 + 防冲刷 + 经济)

1、针对性耐蚀:橡胶衬里对弱 / 中等腐蚀介质(如稀酸、稀碱、污水)适配性强,且成本远低于氟塑料衬里(约为衬氟截止阀的 1/2~2/3),性价比高;

2、防颗粒冲刷:橡胶具有弹性和耐磨性,能缓冲含微量颗粒介质(如污水中的泥沙、矿浆中的细颗粒)的冲刷,避免金属阀体直接受冲磨损,延长使用寿命;

3、密封可靠:橡胶密封面的弹性可补偿阀体、阀瓣的微小变形,且贴合性好,对介质清洁度要求低于金属密封(可耐受微量杂质);

4、流通阻力适中:截止阀结构适配流量调节,橡胶衬里表面光滑,流道阻力系数(ζ≈10~20)低于衬胶闸阀,能耗较低。

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.
