电动衬胶蝶阀

概述:

电动衬胶蝶阀是融合 “橡胶衬里耐弱蚀 / 防冲刷”“蝶阀流通阻力小”“电动驱动自动化” 三大特性的阀门,通过阀体、阀板的橡胶衬里隔绝弱至中等腐蚀介质,借助电动执行器驱动阀板旋转实现介质通断与调节,核心适配水处理、化工、冶金等中低压、含微量颗粒或需自动化控制的工况,尤其适合大流量管路系统。


公称压力:PN0.6~PN2.0MPa

公称通径:DN50~DN600

适用温度:-50℃~150℃

适用介质:弱 / 中等腐蚀介质(稀酸、稀碱)、含微量颗粒介质(污水、矿浆)、高粘度介质(润滑油、糖浆)、卫生级介质


核心优势(耐弱蚀 + 自动化 + 低阻力)

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,成本仅为衬氟蝶阀的 1/2~2/3,性价比高,适合大规模市政或工业管路应用;

2、自动化高效便捷:电动执行器实现远程控制与精准调节,无需人工现场操作,适配无人值守工况(如污水处理厂远程控制系统),且调节型执行器可实时反馈开度,便于系统监控;

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≈0.1~0.5)远低于截止阀、闸阀,能耗低,尤其适合大流量管路(如自来水输水干线、供暖主管路);

4、密封可靠 + 寿命长:偏心结构减少橡胶密封面摩擦,双偏心型号的密封面寿命是同心蝶阀的 2~3 倍;橡胶弹性密封对介质清洁度要求低,可耐受微量杂质,维护周期长(常规使用 2~3 年更换一次衬胶)。

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.
