Its operating principle is that electric energy is changed into mechanical energy by drive unit, then the liquid in the cylinder body forms high and low pressure to drive piston up by impeller circumrotation, so vertical motion is changed into wagging of brake arm by leverage and declutch is completed. This product has passed the experiment test by National Quality Supervise Administration and every technical criterion is accorded with national trade standard.

电力液压块式制动器包括电力液压推动器和块式制动架两部分组成，其工作原理是通过驱动装置的电能变成机械能，通过叶轮旋转，使缸体内液形成高低压腔推动活塞向上运动，从而通过杠杆机构将垂直运动转变成制动臂的左右摆动、完成松闸。

According to the structure characteristics of L-B composite brake beam, the finite element model of L-B brake beam based on contact is established, and the stress distribution of the brake beam in different conditions calculated is using I-DEAS software. Calculated results show that the stress concentration mainly generates in the root of brake header slider, which fit with the faults in actual operation, and provide reliable basis to improve design and optimization.

根据L-B型组合式制动梁的结构特点，运用I-DEAS软件建立基于接触的L-B型制动梁有限元模型，并计算了制动梁在不同工况下的应力分布，计算结果表明应力集中主要发生在闸瓦托滑块根部，这与实际运行中出现的故障较为吻合，为制动梁的改进设计和结构优化提供了依据。

In a normal pipe ram, the two blocks of steel that meet in the center of the wellbore to seal the well have a hole (one-half of the hole on each piece) through which the pipe fits.

在标准的管闸板中，在井眼中间相会，以密封井的两块钢板有一个可以通过钻杆的中孔。

The excess nitrogen atoms in WNx films desorbs at temperatures below 766 ?aC. The excess nitrogen in WNx films can cause the effective work function lowering. Weak Fermi-level pinning effect is observed on HfO2 film. In this case, WNx/HfO2 gate stack can be applied to p-type fully-depletion SOI devices but WNx is not suitable to be meal gate of bulk p-type MOSFTEs.

氮化钨中过多的氮元素在温度低於766 oC便会析出，且过多的氮会导致氮化钨有效功函数下降，在氧化铪上会有轻微的费米栓效应，这种情形下，氮化钨可应用於p-型全空乏绝缘层上矽金氧半场效电晶体元件，但不适合当块材 p-型金氧半场效电晶体闸极。

The bottom of the disc is made of knife-shaped gate with a cut off function of the medium. When gate is closed , oblique plane of gate valve encounters wedge block of gate to achieve sealing effect.

闸板底部做成刀形斜面具有切断介质功能，而且闸板关闭时通过阀体上的锲块紧靠闸板斜切面使得闸板紧紧贴靠阀座密封面，从而起到了密封效果。

Composed of round door frames, gate, rack , sealing strip, adjustable structure of sealing , this kind of sealing principle is door frame is fixed on square pipe of pool and wall, rack is fixed on door frame and wall, through rack opens and closes till weld block of gate meets with weld block of rack to make sealing surface of gate close to sealing surface of door frame to achieve sealing .Besides , sealing of gate and sealing of door frame are made of inlaid copper which is well resistance ,It makes valve with well sealing ,wear resistance , corrosion resistance, easily operation, convenient installation , long life , wildly usage.

本闸门是由圆型门框、闸板、导轨、密封条、可调整密封机构等部件组成，其密封原理是门框固定于水池圆型管道及墙壁上，导轨固定门框与墙壁上，闸板通过导轨做启闭动作，直到闸板上的锲块碰到导轨条上的锲块，使得闸门密封面紧靠门框上的密封面，从而起到密封效果，另外闸板密封面跟门框密封面都是镶铜材质的，具有耐磨损的特性，使得阀门密封密封性好、耐磨性强、耐腐蚀、操作简单、安装方便、使用寿命长、适应性广等特点。
