闸杆

Based on the research and design of the lock wall of the Three Gorges Project,the action of the dead load and temperature load during construction of the temperature and seepage pressure during operation is analyzd,and the stress of the anchor rod of different free lengths is studied in detail.

结合三峡船闸设计研究工作，通过分析闸墙施工过程中自重荷载、温度荷载以及完建运行时温度应力、渗透压力的作用，详细研究了锚杆取不同自由长度时锚杆的应力情况。

Shut off the lower pipe ram, open the choke line and test the next ram and choke line.

关下部钻杆闸板，开放喷阀，试压第二个闸板和放喷泉管线。

Valve:(dark-parallel) 1 - wedge-shaped gate valve; 2 - sleeve nut; 3 - Valve; 4 - stem; 5 - valve cover; 6 - Thrust Convex shoulder; 7 - Packing letter flange; 8 - packing; 9 - Packing Gland, 10 - hand wheel; 11 - valve cover pad.

闸阀：1--楔形闸瓣；2--套筒螺母；3--阀体；4--阀杆；5--阀盖；6--止推凸肩；7--填料函法兰；8--填料；9—填料压盖；10--手轮；11--阀盖垫。

Dark rod knife gate valve with disc buried in the body cavity is completely isolated from the external environment, it is suitable for pip which is installed in the swage pool and body is immersed in the liquid . If disc is not isolated from external environment ,disc will be corrupted immediately , so it will affects life of the valve.

暗杆式刀闸阀是闸板埋在阀体内腔完全与外界环境隔绝的一种阀门，它适合与那些安装在污水池底下阀体浸泡在液体里的管道，如果不把闸板与外界环境隔离，那么闸板就很快会被外界环境所腐蚀，影响了阀门使用寿命。

It is mainly made up of frame, gate board, screw pole, nut etc.Rotate the handwheel by hand, then the screw pole drives the nutand gate board move in horizontal to and fro to open or close thevalve.

主要由框架、闸板、丝杆、螺母等零件构成，用手转动手轮使丝杆带着丝杆螺母和闸板沿水平方向往复运动，达到闸门的启闭目的。

Classified according to location of threaded stem can be divided into Ming and dark rod valve valve two kinds of stroke.

按阀杆的螺纹位置划分，可分为明杆闸阀和暗杆闸阀两种。

Wedge gate valve is usually no valve chamber overpressure protection 2, no clear protection bar gate, not recommended.

契形闸板阀通常没有阀腔超压保护 2、无保护的明杆闸阀，不推荐使用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
