衬胶法兰闸阀

概述:

衬胶法兰闸阀是一种在阀体、阀盖、闸板等与介质接触的核心部位衬覆橡胶(如天然橡胶、丁腈橡胶、氯丁橡胶等)的法兰连接式闸阀,通过橡胶衬里隔绝弱至中等腐蚀介质、法兰实现管路刚性连接,借助闸板直线升降实现介质全开 / 全关控制,核心应用于水处理、化工、冶金等中低压、弱腐蚀或含微量颗粒的工况,不适用于流量调节。


公称压力:PN0.6~PN1.6MPa

公称通径:DN15~DN400

适用温度:-50℃~150℃

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


核心优势(耐弱蚀 + 防冲刷 + 经济)

1、针对性耐弱蚀:橡胶衬里对弱腐蚀、含微量颗粒的介质(如污水、稀酸)适配性强,且成本仅为衬氟闸阀的 1/2~2/3,性价比高,适合大规模市政或工业管路应用;

2、防颗粒冲刷:橡胶具有弹性和耐磨性,能缓冲含泥沙、细颗粒介质的冲刷,避免金属阀体直接受冲磨损,使用寿命是普通铸铁闸阀的 2~3 倍;

3、双向密封可靠:橡胶密封面的弹性可补偿部件微小变形,且对介质清洁度要求低(可耐受微量杂质),密封成功率高于金属密封闸阀;

4、流通阻力小:闸板全开时与流道平行,介质流通截面大,阻力系数(ζ≈0.1~0.5)远低于截止阀,能耗更低,适配大流量管路(如自来水输水干线)。

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.
