电动法兰蝶阀的工作原理:
电动法兰蝶阀蝶板的回转中心(即阀杆的中心)位于阀体的中心线和蝶板的密封面截面上。阀座采用合成橡胶,关闭时蝶板的外圆密封面挤压合成橡胶阀座,使阀座产生弹性变形,从而形成弹性力作为密封比压***蝶阀的密封。
电动法兰蝶阀的适用范围:
电动法兰蝶阀适用于温度≤120℃或≤150℃,公称压力≤1.6MPa给排水、污水、食品、供暖、燃气、船舶、水电、冶金、能源系统以及轻纺等行业,特别适用于双向密封和阀体易锈蚀场合,作调节流量和截流介质。
The working principle of the electric flange butterfly valve:
The rotary center of the butterfly plate of the electric flange butterfly valve (the center of the stem) is located on the center line of the valve body and the cross section of the seal face of the butterfly plate. The seat is made of synthetic rubber, and the rubber seat is extruded by the outer sealing surface of the butterfly plate when it closes. It causes elastic deformation of the valve seat, thus forming elastic force as the seal pressure to ensure the seal of butterfly valve.
