电动密封蝶阀，不锈钢电动法兰蝶阀生产厂家

电动密封蝶阀结构特性：

1、在高温高压工况下，仍具有稳定的密封性能。它的特殊密封系统可保证从超低温至超高温各温度范围都具有较高的密封性能

2、三维偏心密封系统加之人优化的设计，使阀门开启阻力小。蝶板密封面为一向上凸起的锥形，开启时蝶板圆周面上的各点同时完成脱离密封圈，固体物不易在密封面上堆积。阀门关闭过程通过密封圈的弹性受压来完成，

3、蝶板与密封圈之间不存在相卡现象。

4、阀门的密封性能不受温度变化的影响。

5、阀杆轴径密封采用石墨压制成形密封圈。综上所述确保了零泄漏，金属密封加上在火灾前、中、后均为零泄漏，故是本质火灾安全型。

Structural characteristics of electric sealing butterfly valve:

1. It still has stable sealing performance under high temperature and high pressure working conditions. Its special sealing system can ensure high sealing performance in various temperature ranges from ultra-low temperature to ultra-high temperature

2. The three-dimensional eccentric sealing system and optimized design make the valve opening resistance small. The sealing surface of the butterfly plate is an upwardly convex cone. When opening, the points on the circumferential surface of the butterfly plate are separated from the sealing ring at the same time, and the solid matter is not easy to accumulate on the sealing surface. The valve closing process is completed by the elastic pressure of the sealing ring,

3. There is no phase jam between the butterfly plate and the sealing ring.

4. The sealing performance of the valve is not affected by temperature changes.

5. The shaft diameter of the valve stem is sealed with graphite pressed into a sealing ring. In summary, zero leakage is ensured, and the metal seal plus zero leakage before, during and after the fire, it is an intrinsic fire safety type.
