泄水板

Dryer evaporator, heat expansion valve and control box, etc, and choosing packaged imported cooling compressor, famous brand controlling parts, and choosing packaged imported cooling compressor, famous brand controlling parts, and choosing packaged imported cooling compressor, famous brand controlling parts, and condenser used advanced B10 high efficient heat transmitting pipe, and can protect ship swing from flow-stop.

压缩机选用原装德国或美国进口制冷压缩机；冷凝器选用抗腐蚀能力强的海水型专用壳管式冷凝器，冷疑器铜管材质为B10，壳体为A3碳钢，管板、端盖为碳钢加防腐环氧树脂涂层，并且端盖内装有防腐锌块；关键电气控制元件选用进口名牌产品；电控箱内有冷冻水和超低温冰点控制，制冷系统有压力控制和超温泄放装置，有电机过热和电流电压保护措施。

When a sudden power failure or accident or normal pump stops when the pump stops, the valve inlet water velocity to reduce stress Agency, the valve plate also fall, when its velocity is zero (that is, inlet flow rate is zero Department), large valve plate because of its own gravity and rapidly turn off (time 3s ~ 5s), the majority of water to prevent backflow, when the valve before and after the formation of a water pressure, water stress, on the one hand through the small valve at the bottom of the three slot for pressure relief vent pressure. 4 water stress from the bypass tube into the cavity patch up the control room (this process for the suction pressure chamber that can effectively absorb the energy of water), when water stress on cavity than inferior vena cava, the pressure of water promote the diaphragm down mobile , the current cavity pressure of water being squeezed out all the small valve plate slowly drop back to standby status, the process time to ease closure adjustable (3s ~ 150s), then the valve has been fully closed, watertight.

当突然停电或事故停泵或正常停泵时，阀门进水口处压力水流速降低，大阀板也随之下降，当其流速为零时，大阀板由于自身重力而迅速关闭（时间3s～5s），可防止大部分水倒流，此时阀门前后形成一种水压差，压力水一方面通过小阀板底部的三条泄压槽进行泄压。4）压力水从旁通管进入膜片控制室上腔（此过程为吸压腔，能有效吸收一部分水能量），当上腔压力水大于下腔时，压力水推动膜片往下移动，当下腔压力水全部被挤出来时，小阀板缓缓下降，恢复到待机状态，此过程中缓闭时间可调节（3s～150s），届时阀板已全部关闭，滴水不漏。

Chain lockers to be provided with drain well of sufficient capacity, covered by perforated, removable and galvanised steel plate.

锚链舱中应布置有具有足够容量的泄水阱，阱的顶部装有镀锌钢板制成的可拆型多孔板。

Down sliding track using Step-down design, no drainaging board, draining water smooth , waterproof performance better.

阶梯式下滑，无档水板，排水泄水顺畅无阻，加高档水设计，防水性能更佳。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
