进口电动Y型疏水阀结构特点：

①阀门上部由阀盖和填料箱组成，利于快速拆装以及在原地维修。倾斜阀杆的构造和最jia的流道形状设计使介质近于直线的方式，阀门具有最jia的Cv值，产生比其它形式阀门更低的压降。

②阀门本体上以特殊工艺堆焊硬质合金密封面（密封面表面经过整体硬化处理），结构更紧凑。锥形密封面设计使较小的轴向力就可密封，能提供可靠的密封和长久的使用寿命。

③采用阀体中腔导向的阀瓣具有上下两个导引环，阀瓣的顶部和底部同时导向，构成全程在阀体中腔导向的活塞式阀瓣，可以消除因各种受力不当产生的卡死，表面擦伤，阀杆弯曲，阀瓣振颤等现象。阀瓣底部的导引环将90%的流体以接近直线的方式通过，有效地消除所有侧面冲击引起的不良反应。这些特点使该阀门很适用于电站蒸汽快速"排放"和"疏水"系统。

④阀瓣密封面堆焊硬质合金，该合金具有*的机械特性，耐磨损，耐冲蚀，可保持阀门长久的使用寿命。

⑤阀杆填料采用进口的特种填料，能起到最jia的防漏效果，并且经久耐用，拆装方便。填料箱与阀体处的密封采用夹316高目柔性石墨垫，以预定的扭矩进行装配,安全可靠，杜绝外漏。

⑥采用气动装置作为执行机构,对阀门的控制 ,安全,有效.

⑦填料箱采用特殊结构设计，保证足够的强度和良好的热学特性。

Structure characteristics of inlet electric Y-type drain valve:

① The upper part of the valve is composed of valve cover and packing box, which is convenient for quick disassembly and in-situ maintenance. The structure of tilt stem and the shape of the most Jia channel make the medium close to the straight line. The valve has the most Jia CV value, which results in lower pressure drop than other valve forms.

② The valve body is equipped with special process to overlay the sealing surface of cemented carbide (the sealing surface is hardened as a whole), and the structure is more compact. The conical sealing cover design makes the sealing with small axial force, and can provide reliable sealing and long service life.

③ The valve disc guided by the middle cavity of the valve body has two guiding rings, the top and bottom of the valve disc are guided simultaneously, which forms the piston valve disc guided in the middle cavity of the valve body. It can eliminate the jamming, surface scratch, valve stem bending and valve disc vibration caused by various improper force. The guide ring at the bottom of the disc passes 90% of the fluid in a straight line way, effectively eliminating the adverse reactions caused by all side impacts. These characteristics make the valve suitable for the rapid "discharge" and "drain" system of steam in power station.

④ The sealing surface of valve disc is overlaid with cemented carbide, which has excellent mechanical properties, wear-resistant and erosion resistance, and can maintain the long service life of the valve.

⑤ The valve stem packing adopts imported special packing, which can play the most Ji leakage proof effect, and it is durable and easy to dismantle. The packing box and valve body are sealed with 316 high mesh flexible graphite gasket, which is assembled with the predetermined torque, which is safe and reliable, and the leakage is eliminated.

⑥ The pneumatic device is used as the actuator to control the valve accurately, safely and effectively

⑦ The packing box is designed with special structure to ensure sufficient strength and good thermal properties.

进口电动Y型疏水阀产品简介：

德国洛克《DE LOCKE》进口电动Y型疏水阀主要用于在机组启动阶段，排出各段蒸汽管道中的汽水混合物，直到汽轮机正常运行。另外在汽轮机出现故障或甩负荷时，按程序将疏水阀打开，将管道中蒸汽、水排至疏水扩容器，保证系统安全。

Introduction to imported electric Y-type drain valve products:

The imported electric Y-type drain valve of de lock in Germany is mainly used to discharge the steam water mixture in each steam pipe during the unit start-up stage until the steam turbine is in normal operation. In addition, in case of turbine failure or load rejection, open the drain valve according to the procedure, and drain the steam and water in the pipeline to the drain flash tank to ensure the system safety.
