产品简介与用途
三偏心金属密封蝶阀，采用"U"型不锈钢密封圈，该阀精密的弹性密封圈与经过抛光的蝶板，三维偏心密封面接触，而者有机的结合具有耐高温、高压、低温等技术参数，因此被广泛应用于介质温度≤550℃的冶金、电力、石油、化工、空气、煤气可燃气体及给排水等腐蚀性介质的管道上，是调节流量和截断流体的最佳装置。
双偏心四氟骨架密封蝶阀是介于软密封橡胶蝶阀良好的密封性能，又具有金属密封耐温、耐压等特点，因此被广泛应用于介质温度≤180℃的石油、冶金、电力、市政工程、水厂等管道上，作定向控制介质流向的启闭机构。
特点：
三偏心金属密封蝶阀

Product description and usage:
Three eccentric metallic sealing butterfly valve employs "U"-shaped stainless steel sealing ring .With the contact of precision elastic surface ,such organic combination enables the technical parameters of resistance against high temperature , high pressure and low temperature etc. Hence , they have been widely used in pipeline with corrosive mediums in metallurgy , power , petroleum, chemicals, air, ignitable gas like coal gas ,as well as feedwater and drainage etc .,which medium temperature is ≤550℃.It is an optimal device to adjust flow and cut off fluid.
Features:
Three-eccentric metal seal butterfly valves
1 Three eccentric metallic seal butterfly valve is simply structured, compact, lightweight, easy for installation and disassembly ,and conveniently maintainable.
2 This butterfly valve employs stainless steel "U"-shaped sealing performance with disc under whatever conditions of high temperature and low temperature.
3 The three-dimensional eccentricity of this butterfly vavle is subject to strict calculation to enable almost non-friction between "U"-shaped sealing ring and disc for long performance life and the function of closer seal upon off.
4 Disc sealing surface employs deposited cobalt-base hard alloy for abrasion resistance and long performance life .
5 Endurance against high temperature ,low temperature and corrosion
