变压器蝶阀 蜗轮法兰系列DN40-1200 变压器配件 蝶阀阀门 逆止阀

　　优点

　　advantage

　　1、启闭方便迅速、省力、流体阻力小，可以经常操作。

　　1. The utility model has the advantages of convenient and rapid opening and closing, labor saving, small fluid resistance and regular operation.

　　2、结构简单，外形尺寸小，结构长度短，体积小，重量轻，适用于大口径的阀门。

　　2. It has the advantages of simple structure, small overall size, short structural length, small volume and light weight. It is suitable for large-diameter valves.

　　3、可以运送泥浆，在管道口积存液体最少。

　　3. The mud can be transported and the liquid accumulated at the pipe mouth is the least.

　　4、低压下，可以实现良好的密封。

　　4. Good sealing can be achieved under low pressure.

　　5、调节性能好。

　　5. Good adjustment performance.

　　6、全开时阀座通道有效流通面积较大，流体阻力较小。

　　6. When fully open, the effective flow area of the valve seat channel is large and the fluid resistance is small.

　　7、启闭力矩较小，由于转轴两侧蝶板受介质作用基本相等，而产生转矩的方向相反，因而启闭较省力。

　　7. The opening and closing torque is small. Because the butterfly plates on both sides of the rotating shaft are basically equal under the action of media, the direction of torque is opposite, so the opening and closing is labor-saving.

　　8、密封面材料一般采用橡胶、塑料、故低压密封性能好。

　　8. The sealing surface materials are generally rubber and plastic, so the low-pressure sealing performance is good.

　　9、安装方便。

　　9. Easy installation.

　　10、操作灵活省力，可选择手动、电动、气动、液压方式。

　　10. The operation is flexible and labor-saving, and manual, electric, pneumatic and hydraulic modes can be selected.
