Editing features of this paragraph

　　美标法兰蝶阀具有密封面耐磨损.耐腐蚀.使用寿命长.结构排除了其他类型蝶阀开过位而不能密封的缺点，且在高曙下能正常使用，克服了其它类型阀门在高温使用时因热膨胀而容易泄漏的缺点。主要集中在以下方面：

American standard flange butterfly valve has a sealing surface wear resistance. Corrosion resistance. The service life is long. The structure and exclusion of other type butterfly valve open and can not be sealed faults, and can be used in high Shu, overcome the other valve types when used in high temperature due to thermal expansion and easy leakage faults. Mainly in the following aspects:

　　①三向偏心的独特设计使密封面之间无摩擦传动，延长了阀门使用寿命。

Three to the unique design of the eccentric sealing surface between the friction free transmission, prolonging the service life of the valve.

　　②由扭矩产生弹性密封。

The torque generated by the elastic sealing.

　　③巧妙的楔形设计使阀门有越关越紧的自动密封功能，密封面之间具有补偿性、零泄漏。

Wedge cleverly designed so that the valve has the function of automatic sealing more closed more tightly, with compensatory, zero leakage sealing surface.

　　④体积小、重量轻、操作轻巧、便于安装。

The small volume, light weight, easy operation, easy to install.

　　⑤可根据用户要求配置气动、电动装置，满足遥控和程控的需要。

It can be configured according to user requirements of pneumatic, electric device, to meet the needs of remote control and program control.

　　⑥更换零件材质可适用于各种介质，并可进行衬里防腐（衬F46、GXPP、PO等）。

Replacement parts can be applied to various dielectric materials, and the anti-corrosion lining (lining F46, GXPP, PO etc.).
