适用于连铸辊、蒸汽阀、楔形阀、安全阀等部件的硬面堆焊。
It is for hardfacing of continuous casting roll, steam valve, wedge-shaped valve, safety valve, etc.
当关闭通道时，用阀杆的楔形头使球体涨开与阀座压紧达到密封。
When the closed channel, the wedge-shaped head with a stem to open up the ball and pressed to seal the valve seat.
闸板有两个密封面，最常用的楔式闸板阀的两个密封面形成楔形，楔形角随阀门参数而异。
Gate has two sealing surfaces, the most commonly used wedge gate valve sealing surface to form two wedge-shaped, wedge Angle parameters vary with the valve.
采样管的里端头为与逆止阀的内口径呈上斜面的单面楔形；
The inner end of sampling tube is one-sided slant wedge with the caliber of check valve;
闸阀和截止阀具有各种楔形闸板或阀瓣和阀体的配置，适用于不同的应用场合。
Gate and globe valves are available with a selection of wedge or disc and body configurations for different services.
我们提供的闸阀的结构形式具有两种：平行阀瓣和弹性楔形闸板。平行阀瓣为定位阀座密封；弹性楔形闸板在关闭时则是扭矩阀座密封。
Gate valves are offered in two designs: Parallel Disc and Flexible Wedge. Parallel Disc are position seated; Flexible Wedge are torque seated when closing.
而且由于阀杆的楔形块与燕尾槽的作用，对阀门增加了强制密封力，增大了密封比压，实现双向密封。
And because the wedge block and the role of the dovetail groove of the stem, the valve increases the forced sealing force, increases the sealing pressure ratio, the two-way sealing.
