1、 吊运 开箱后用吊车吊运蝶阀，起吊时应注意在四个吊环螺钉中选取平衡位置，避免液压油溢出或碰伤零部件。 液控缓闭止回蝶阀若较长时间存放时，应放于干燥处，封闭两端通道，在加工面涂上防锈油。临时停放时可在外墙板位置增加辅动支承以保持平稳（固定安装时可根据稳定性情况取舍）。半年不安装，液压系统需清洗换油。 2、 安装 安装前应核对液控缓闭止回蝶阀铭牌参数是否符合使用要求。 清洗阀体内孔及蝶板、检查各部位有无损坏现象，各连接螺栓是否紧固。 将阀门安装配图所标液流方向安装在泵出口端或水轮机进口端（阀门采用反装结构时传动机构在图示管道的另一侧），伸缩节装在另一端以便装拆。 3、 试车 根据液压原理图检测各控制阀是否在所需要位置。 接上总电源，启动电机观察电机风叶，顺时针旋转则接线正确。 按使用说明书依次核实开阀、保压、关阀、停止动作以及程序和参数是否相符，一般开、关阀程序出厂时已按常用工况调好，用户如需要按所在泵站的工况调整时，可来人、来函在我公司办理计算和调整手续（也可在订货时提出有关参数，以便我公司预先调好）。 试车中检查压力变化是否正常：液压系统不得有泄漏，阀体轴封不得有泄漏。 4、 运行 配置联动控制电路，与水泵联动操作空负荷运行核实程序及参数。 上述工作合格即可进入负荷运行试验（动水状态下），运行中需检查下列几项： a 开阀过程中阀前阀后压力变化比较平稳，全开后基本相近。 b 是否能按程序与水泵、水轮机联动关阀。 5、 润滑 液控缓闭止回蝶阀液压油为HJ-20#液压油或HU-22#汽轮机油，油位应不低于油标中线。过滤网每半年清洗一次。液压油每年抽样检查一次，检查其清洁度和润滑性，如不符合要求，则应更换。油箱标定容积为40升。

1, lifting Out of the box after the use of cranes lifting valve, lifting should pay attention to the four rings, screws, select the position of equilibrium, to avoid hydraulic oil spill or bruised parts. Fluid control slow closed-return valve if longer storage should be kept in dry place, closed at both ends of passage in the processing of surface coated with anti-rust oil. Temporary parking may outer wall position to increase secondary dynamic bearing in order to maintain stable (fixed installation according to the stability of the situation a choice). Six months is not installed, the hydraulic system needs to clean oil changes. 2, the installation Install former should check hydraulic control slow closed-return valve plate parameters are consistent with requirements. Cleaning the valve body bore and the disc, check each part for damage phenomenon, the connection bolts are tightened. The valve is installed with plans by the standard flow direction with the pump outlet or the turbine inlet (valve with anti-loaded structure of the transmission mechanism in the icon pipeline on the other side), expansion joint installed at the other end for assembly and disassembly. 3, test According to hydraulic schematic diagram to detect the control valve is in need here. Connected to the mains, start the motor observation of motor fan, clockwise rotation of the wiring correct. By using the manual order verification of open valves, packing, customs valve, stop the action and the procedures and parameters are consistent with the general opening and closing valve procedures for the factory has been under common conditions fine, the user such as the need to press where the pump station condition adjustment , may come, letter in my company to complete the calculation and adjustment procedures (also available on order, relevant parameters for our pre-stressed good). Test to check the pressure is normal: hydraulic system may have leaks, valve seal may not have leaked. 4, run Configuration interaction control circuit, and the pump linkage operation load Operation verification procedures and parameters. The above-mentioned qualified to enter the Load Test (dynamic water conditions), the operation need to check the following: a valve open during the valve before the valve after the pressure is relatively stable, fully open, are basically similar. b whether according to the procedure and the pumps, turbines linkage off valve. 5, lubrication Fluid control slow closed-return valve hydraulic oil for the HJ-20 # hydraulic oil or HU-22 # turbine oil, the oil level should be not less than oil standard midline. Filter every six months clean time. Hydraulic oil every year sampling time, check the cleanliness and lubrication, if not meet the requirements, should be replaced. Tank calibration volume of 40 liters.
