This paper has discussed the focal point of design scheme and article of the two pillar stacker crane of universal use in modern most enterprises in detail put , in thirdly parts: elevator Gou , walk organization and fork telescoping mechanism design , design a kind of tape the cranes safe organization of flexible installation design scheme.

本文详细论述了在现代大多数企业中普遍使用的双立柱堆垛机的设计方案，文章的重点放在其三个部件：升降机构、行走机构、货叉伸缩机构的设计上，并设计一种带柔性装置的堆垛机安全机构的设计方案。

The cut-off valve with pilot valve without hand wheel, stem and lift nut inside will guide block and guide slot Butterfly Valves to guide sleeve, the disc-shaped disc to disc type bowl shape, and holes in the bottom of the flap valve to open, the valve cover of the original valve stem hole to hole diversion, because of increased pressure ring, ring, and the valve flap to class mortar, so that the flow passage separated the upper chamber cavity, external cavity, cavity, in the cavity and The external cavity increases with draft tube and stainless steel manual ball valve, flap valve in the cover plate and the center of the end of installing the spring, the upper flap valve install compression seal of the pressure ring, outside the cavity of the wall to open a Drainage holes.

带先导球阀的截止阀无手轮、阀杆和内升降螺母，将导向块与导向槽改为导向套，将盘形阀瓣改为类钵体形阀瓣，并在底部开阀瓣孔，电动蝶阀将阀盖原阀杆孔改为导流孔，因增加压环、密封圈和将阀瓣改为类钵体，使上通流腔分隔为上腔、外腔、内腔，在上腔与外腔的外部加设有导流管与不锈钢手动球阀，在盖板与阀瓣底的中心部加设弹簧，阀瓣上部加设压紧密封圈的压环，在外腔的壁上开有放水孔。

As a downstream piping system when the valve opens, reflux valve, when closed, the main medium used to prevent backflow to prevent the pump and drive motor reversal, as well as a container medium discharge; currently the most commonly used is the valve flap around the body Swing Pin rotation flap valve and the valve body along the vertical axis to move lift check valve, but the above two kinds of structures exist in the valve closed, medium speed back quickly from the largest drop to zero, inlet side of the pipe resulted in the rapid pressure rise, resulting Proportional Pressure Reducing Valves in damaging effects on the piping system of water hammer phenomenon, it is generally a diameter of valve production of 50 ~ 500 mm.

止回阀作为管道系统顺流时开启，逆流时关闭的阀门，主要用于防止介质倒流，防止泵及驱动电机反转以及容器内介质泄放；目前使用最普遍的是阀瓣围绕阀体销轴旋转的旋启式止回阀和阀瓣沿着阀体垂直中心线移动的升降式止回阀，但以上2种结构的阀门均存在关闭时介质倒流速度从最大迅速降为零，致使管道进水管一侧内压迅速升高，从而产生对管路系统有破坏作用的水锤现象，所以一般止回阀生产口径为50～500 mm。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
