閘門及導槽技術規(guī)格翻譯-中英
1）閘門
閘門由鋼板和型鋼焊接而成，由預制截面的彈性氯丁橡膠密封條沿四周密封，并用壓板和緊固件固定。閘門為靜水啟閉，只承受單向水壓力，采用單向止水。每個閘門帶有平衡閥。平衡閥的動作是升降程序中的一部分，抓梁吊鉤抓合后，在提升閘門之前提升并打開平衡閥引水以平衡閘門兩側壓力。當兩側壓力達到平衡時，再提升閘門。閘門在側面導槽中由滾輪和導向塊定位，把橡膠密封條壓在密封面上密封。閘門上帶有觸底探測裝置以防止在閘門下降過程中被卡在導軌上使抓梁吊鉤意外脫扣。
2）導槽
導槽包含密封角鐵、底檻、門楣和上端導軌角鐵，均由角鋼制成用螺栓和調整螺母固定。錨板在一次灌漿中安置。在安裝時，螺栓焊接到錨板上，用調整螺母將導槽及各個部件精確找正對準。導槽材質為耐海水腐蝕的，導槽高度為全槽結構。
3）防腐要求
采用防腐涂料加犧牲陽極塊聯(lián)合保護，設計總的使用年限為60年。

7） 泄漏
閘門是水密性的，但在出現低水阻或密封構件被污物墊塞時會發(fā)生一些泄漏。當閘門完全浸沒時每米密封長度的最大泄漏率為0.05L/s，部分浸沒時最大泄漏率為0.l L/S。
8） 起重能力
設備數據參數表中給出的重量是閘門的自重。在起重時，為了克服閘門與密封面間的摩擦和在導槽上的咬和黏附作用，建議需要升降的重量按閘門自重的兩倍估計。
9） 閘門自動抓梁裝置技術規(guī)格
自動抓梁裝置在閘門升降過程中可以自動抓合和脫扣。自動抓梁裝置兩端帶有導向塊使其在導槽中定位并與閘門升降點對準。吊鉤與決定其開合偏差的轉軸組件相連接。在升降過程中，轉軸組件的精確動作可使吊鉤與閘門自動抓合或脫扣。抓梁帶有一個連鎖裝置以防止在測量裝置動作前升降桿與閘門脫扣。
c) Technical specification of strobe and guide barrel
1）Strobe
A strobe is welded by steel plate and steel section, which is sealed around by electrometric neoprene seal with preformed section and fixed by a pressure plate and a fastener. The strobe shall apply static water open-close, only bearing unidirectional pressure and adopting unidirectional water stopping. Each strobe is set with a balance valve. The movement of balance valve is a part of lifting and lowering processes. After the lifting hook of grabbing beam has grasped, it is required to lift and open the balance valve for drawing water to balance the pressure on both sides of strode before exalting it. When both sides have been balanced, strode will be lifted. A strode is positioned by a trolley and a guide block in the guide barrel on one side, pressing rubber seal on a sealed surface for sealing. The strode is installed with a bottom finding detection facility to prevent strode from being blocked on guide rail during descending, causing lifting hook of grabbing beam to escape away accidentally.
2）Guide barrel
The guide barrel consists of a sealed angle iron, bottom sill, door head and an upper guide rail angle iron, which are all made of angle steel and fastened by bolts and adjusting nuts. An anchor plate is installed during one time of grouting. During installation, the bolt is welded into the anchor plate, aligning the guide barrel and each part correctly with the adjusting nut. The material of guide barrel is seawater corrosion resistant and the height of guide barrel includes the whole structure of the guide barrel.
3）Anti-corrosion requirements
Combined protection by using preservative coatings and sacrificed anode is applied and the total service life is designed to be 60 years.
4）Data of plant site
Tidal levels of outer-sea are:
SEC designed highest tide level: 7.58m
CRF designed highest tide level: 4.54 m
CRF designed lowest tide level: -1.47m
SEC designed lowest tide level: -3.35m
The water levels of front tank（sea reservoir）of pump room are:
CRF designed lowest water level: -6.72m
SEC designed lowest water level: -8.00m
5）Equipment data
The elevation of orifice of strobe:
Top： -7.0m *
Bottom： -11.5m*
Elevation of operation platform 8.0m*
Width of water channel: 5.5m*
Number of strobe: 16（8 for each unit）
Width: 5.5m*
Height: 4.5m*
Weight:
Designed head difference: 9.1m*
Number of guide barrel: 16 set（8 for each unit）
Length of guide barrel: 20.0m*
6） Engineering material
Structure of strobe: Carbon steel
Balance valve: Carbon steel
Seal: Neoprene
Guide barrel: 316L
7） Leakage
The strobe is water tight, but leakage may occur when low water resistance takes place or the sealed component is padded by dirt. When the strobe is completely immerged, the maximum leakage rate of seal length per meter is 0.05L/s, and the maximum leakage rate of seal length per meter is 0.l L/S if it is partly immerged.
8） Lifting capability
The weight shown in the parameter table of equipment data is the dead weight of strobe. During lifting, it is suggested that two times of dead weight for lifting should be reuired to overcome the friction between strobe and seal surface as well as bite force and adhesive action on guide barrel.
9） Technical specification of automatic beam grabbing device for strobe
The automatic beam grabbing device can grasp and trip automatically during lifting of strobe. Guide blocks are installed on both sides of the automatic beam grabbing device for positioning in the guide barrel and aligning with rise-fall dot of strobe. The lifting hook is connected to components of rotating shaft which decides its retractable deviation. During lifting, the accurate action of rotating shaft will help the lifting hook and strobe grasp or trip automatically. The grabbing beam is set with an interlocking gear to prevent lifting bar and strobe from tripping before the movement of measuring device.
