水轮机进水重锤式液压控制蝶阀产品使用说明书 The following text is amended on 12 November 2020.一、主要性能特点、用途及适用范围本产品为新型的水轮机进水重锤式液压控制蝶阀，全称为希斯威系列水轮机进水重锤式液控蝶阀或希斯威系列水电站开阀锁定型自动保压重锤式液控止回蝶阀，分普通型和防泥沙型两种，防泥沙型液控蝶阀用于水中含泥沙等杂质较多的水电站工程。

希斯威系列液控蝶阀开启采用液压驱动，油压可达16Mpa，减少了接力器的体积，开启过程中，同时将一重锤举起，利用举起的重锤蓄能关闭，取消蓄能罐，开启后锁锭自动投入，液压系统自动保压，重锤不下掉，蝶板不抖动。

关闭时不需动力油源，自动解除锁锭销、按预定的程序关闭，简单可靠，大大简化了液压系统。

采用双偏心阀板，水平安装的阀轴在管道中心线上抬高一定距离，使阀板下半部迎水面积大于上半部，能利用动水力的作用帮助阀门关闭以减小重锤的重量，将结构简单、体积小的油压装置、蝴蝶阀控制柜、电气自动控制箱、接力器、控制油管很紧凑的与阀门集聚在一起，不需用户另外配置。

该阀能实现就地控制、远方控制及联动控制，可满足“无人值班、少人值守”的要求，是一种理想的新型管路控制设备。

这种液控蝶阀是水电站中管线系统截断或接通介质的理想设备，适用于装在水轮机前的压力钢管处，作为水轮机进水阀，其作用为：1、水轮机发生事故且导叶不能关闭时，动水关闭阀门，紧急关闭截断水流，防止水轮机发生飞逸，确保机组安全。

2、机组停机备用时，关闭阀门，截断水流，防止水轮导叶长期漏水，既减少水能损失，又可防止在导叶端面和立面处产生间隙气蚀。

3、机组停机检修时，静水关闭阀门，截断水流。

本蝶阀还适用于高位布置在压力钢管的始端，用作压力钢管保护阀，在压力钢管发生爆裂等情况时紧急关闭截断水流，防止事故扩大，确保安全。

本系列蝶阀的驱动装置可根据厂房的需要设计在水流方向的左边或右边，重锤可根据电站需要而设计成倒向顺水流方向或逆水流方向。

通常情况下，还原性物质主要是有机物，因此，化学需氧量也是作为有机物相对含量的指标之一。

化学需氧量测定方法通常是重铬酸钾法或高锰酸钾法。

欧美多采用重铬酸钾法，日本则广泛采用高锰酸钾法，我国根据自己的国情规定了用重铬酸钾法测定化学需氧量。

COD-571型化学需氧量分析仪是采用比色法测定化学需氧量的实验室仪器。

参照了我国有关化学需氧量的测定方法，我们专门设计了与分析仪配套的消解装置，可同时进行21个样品加热回流仪器，具有体积小，操作方便，节约大量水、电及试剂，减少二次污染等优点,主要适用于焦化、造纸、石化、印染、皮毛、制革、制药、试剂、食品加工等工业废水中化学需氧量的测定。

1.1仪器的主要特点1.采用单片机技术，中文菜单显示操作简单明了。

2.COD分析仪可直接读取COD结果，无需滴定等其它方法进行分析。

3.采用PP40打印机，可将结果打印输出。

1.2仪器的正常工作条件1.环境温度：(5～35)℃；2.相对湿度：不大于85％；3.供电电源：AC(220±22)V，频率(50±0.5)Hz；4.周围空气中无腐蚀性的气体存在；5.周围无影响性能的振动存在；6.周围除地磁场外无其它影响性能的电磁场干扰。

The dry cells are not installed on receipt of the instrument.4 Operation1. Install four AA cells. When using an external power supply, do not install the dry cells. Supply power only through the external power supply.2. Simply plug-in the BNC output connector to the vertical input of a oscilloscope, and connect the auxiliary grounding terminal to a proper ground. If necessary, use a ground extention lead.3. Select the proper range setting. For higher resolution and less noise when measuring signals below 350V, switch the attenuation to 1/100. Otherwise, set the attenuation to 1/1000 when measuring signals above 350V.4. If the offset voltage is large, short the top of input leads, and turn the ADJUST variable resistor (DC voltage adjustment) using a flat-head screwdriver to adjust the offset voltage.• To protect against electric shock the ground side of the output cable (the shielded side of the BNC connector) must be grounded.• Make sure to avoid an electric shock when connecting the probe to the object ofmeasurement. Do not remove the probe from the measuring instrument after the object of measurement is connected.• When disconnecting the probe BNC output connector, first turn OFF the power to the circuit under measurement. Then, disconnect the probe from the high voltage parts of the circuit under measurement.• When replacing batteries or connecting an external power supply, first turn OFF the power to the circuit under measurement. Then, remove the input lead from the circuit under measurement.CAUTION• This probe is to carry out differential measurement between two points on the circuit under measurement. This probe is not for electrically insulating the circuit under measurement and the measuring instrument.• Use a soft cloth to clean the dirt. Prevent damage to the probe. Avoid immersing the probe, using abrasive cleaners, and using chemicals contains benzene or similar solvents.Note• Connect the BNC connector to the input terminal of the oscilloscope and for two pointmeasurement (differential measurement), connect both input leads. Because the performance declines in case you carry out measurements with only one input lead connected, make sure to always connect both.• Accurate measurement may not be possible near objects with strong electric fields (such as cordless equipment, transformers, or circuits with large currents).5 SpecificationsItemSpecificationsFrequency bandwidth *1DC to 100 MHz (−3 dB)Input typeBalancing difference inputAttenuation ratioswitched ratios of 100:1 and 1000:1Output offset voltage *1 *2±7.5 mVInput resistance and capacity 4 M Ω + 10 pF each side to groundDifferential allowable voltage ±1400 V (DC + ACpeak) or 1000 Vrms at 1000:1 attenuation (between + − terminal)±350 V (DC + ACpeak) or 250 Vrms at 100:1 attenuation Max common mode voltage ±1400 V (DC + ACpeak) or 1000 Vrms Max input voltage(to ground)±1400 V (DC + ACpeak) or 1000 VrmsCMRR (typical)*160 Hz: less than −80 dB; 1 MHz: less than −50 dB Output voltage *1±3.5 V (DC + ACpeak)Output impedance Using 1 M Ω input system oscilloscopeGain accuracy *1±2% (common mode voltage ≤ 400 V and ≥ −400 V)±3% (common mode voltage ≤ 1000 V and ≥ −1000 V)Operating environment 5 to 40°C, 25 to 85% (no condensation)Storage environment −30 to 60°C, 25 to 85% (no condensation)Operating altitude 2,000 m or lessPower requirements *3Internal battery: four dry cells (AA, R6)External power supply:6 VDC/200 mA or more, or 9 VDC/150 mA or more.From the DL series instrument’s probe power supply, 700938, or 701934 using the probe’s power supply cable.

(The electromagnetic brake leads have polarity. The electromagnetic brake will not operate if the leads are connected in reverse polarity.)For the electromagnetic brake, use a power supply of 24 VDC ●±5%, 0.1 A or more for DRL42, or 24 VDC ±5%, 0.3 A or more for DRL60.To connect the electromagnetic brake to the DC power supply, use a ●shielded cable of AWG24 or thicker and keep the wiring distance to a minimum. Be sure to use the supplied surge suppressor to protect switch contact and suppress noise.Notes on Wiring◇Use twisted-pair wires of AWG24 to 22 and 2 m (6.6 ft.) ● or less in length for the signal lines.Note that as the length of the pulse signal line increases, the maximum ●transmission frequency decreases. Technical reference ➜ F-67Use wires of AWG22 for the power supply lines.●When assembling the connector, use the hand-operated crimp tool or the crimped driver lead wire set (sold separately). The crimp tool is not provided with the package. It must be purchased separately.Signal lines should be kept at least 2 cm (0.79 in.) away from power lines ●(power supply lines and motor lines). Do not wire the signal lines with the power lines in the same duct or bundle them together.Extension of the motor leads should be within 10 m (32.8 ft.).●If noise generated by the wiring and layout of motor cables and/or power ●cables causes a problem, try shielding the cables or insert ferrite cores.Incorrect connection of DC power input will lead to driver damage. Make ●sure that the polarity is correct before turning the power on.Connection Diagram●DriverController Input/Output Signal Connection◇Keep the input signal V ●0 between 5 VDC and 24 VDC.When V 0 is equal to 5 VDC, the external resistor R 1 is not necessary.

This value varies greatly depending on the actuator type and load inertia.Pulse Input Mode ◇1-Pulse Input Mode●The 1-pulse input mode uses "Pulse" and "Rotation Direction" signals. When the "Pulse" input is switched from ON to OFF while the "Rotation Direction" input is ON, the screw shaft moves one step forward.

产品详细信息D71X脱硫蝶阀产品介绍：大气污染中，二氧化硫是重要污染物，而二氧化硫污染物60%以上来源于工业烟气的排放。

随着我国环境标准的逐步完善和提高，以及国民对环境意识的提高，我国今后对有工业烟气排放的工程必须进行脱硫处理。

烟气脱硫装置中的重要部件之一就是阀门，对于脱硫阀门的要求是既能耐氯化物、氧化物、酸，又能耐苛刻的磨粒磨损和泥浆的磨损腐蚀。

正确的选择阀门材料和结构形式，延长阀门的使用寿命是烟气脱硫蝶阀的关键。

在众多的工业或电力领域需要有一套完整的脱硫系统.目前，国际上采用的是石灰石－石膏湿法，一炉一塔脱硫装置，该脱硫装置的脱硫效率可达到95.5%。

石灰石浆液系统经过脱硫管道后介质会出现较强的腐蚀性，对整个管道系统和流体控制阀门以及阀门执行器都有着极高的要求。

脱硫专用蝶阀就是针对脱硫系统的特殊要求设计制造的。

脱硫脱硝蝶阀专为电厂脱硫脱硝工程而设计，充分考虑了脱硫浆液对阀门的腐蚀和磨损，保证阀板衬里是唯一能够接触到浆液的部件，而其他部件不被石灰石（或石灰膏）浆液腐蚀。

因此，阀体和阀杆就不需要采用昂贵的合金(2205)材料，从而大大节约了成本。

脱硫蝶阀独特的阀座设计完全把阀体与流体介质隔开，与其他同类阀门比较，它有更佳的阀座牢固方式、就地更换阀座快捷、阀门保持零泄漏、且摩擦小。
