Transport,installation,commissioning,maintenance or repair must only be performed by trained or instructed personnel.WarningIn order to ensure successful and safe operation of our valves the entire operation manual must have been read through and understood prior to installation and commissioning.Under certain operating conditions,the use of damaged equipment could cause a degradation of the performance of the system which may lead to personal injury or death.If you have any questions about problems arise,contact UNICON office.Installation &Maintenance ManualTrunnion-Mounted Ball Seat RingSeat InsertSpring1-3Principle of OperationThe main function of the Trunnion Mounted Ball Valve is to cut off or connect the flow of fluid in a pipeline system.Via the manual hand wheel or other driving device,application of torque force allows the ball to rotate 90degrees,enough to align the ball bore to the centerline passage of the ball valve body,thus allowing fluid to pass through it.2.Pre-InspectionBefore installation of valve to the ‘Pipe Line’,it is recommended to inspect a valve closely as below.4Installation&Maintenance Manual2-1.Inspecting Valve&Accessory-Ensure any damage that might be occurred during the transportation.-Remove the protection cover of valve just before installation and clean a dust or harmfulparticles with an air blaster or smooth dust cloth/clean towel.-Check the tightness of all kinds of bolts and nuts.2-2.Inspecting Pipeline-Remove foreign materials such as a rust,welding chip,etc,which remain in the pipe orflange.-Make sure the clearness of pipe flange and gasket surface.Caution:When the fluid is flowing through the line,any foreign material is subject to scratch theseat and inner body,so that the scratch may cause leakage and shortening of the valvelifetime.To avoid product damage,inspect the valve before installation for any damage or anyforeign material that may have collected in the valve body.Also remove any pipe scale,welding slag,or other foreign material from the pipeline.3.InstallationIt is recommended to install valves on horizontal piping in a upright position.3-1Check the following items before valve mounting1.Service conditions should be within the valve specifications.2.Valve flanges should correspond with piping flanges.3.Gasket contact surfaces of pipes and valve flanges must be thoroughly inspected tomake sure no scratch or any other indication of flaw is found.4.The appropriate length should be kept between pipe flanges for the valve face-to-facedimensions including gasket thickness.5.The valve and pipe center should be aligned accurately.6.Bolt holes of flanges should be arranged symmetrically lined up against the center lineof flanges.57.Remove flange covers from valves just before installation.8.Check all stud bolts /nuts after installation and retighten them,if needed.Installation &Maintenance Manual Caution Before installation,the connecting pipes should be cleaned to remove any foreign object such as sand dust and welding spatters from the connecting pipe interior.CautionHandle valves carefully so that they may not fall or drop on the ground.Any extraordinary mechanical impact should be avoided.CautionPiping should be flushed before test operation,with valves open to assure removal of any foreign object that could damage valves.DO not operate valve during flushing.3-2Installation Procedure1.Make sure that pipes should be aligned accurately.2.The length between piping flanges should correspond with the valve face-to-face including gasket thickness.3.Place the valve between pipe flanges.Install two stud bolts at the bottom of the flanges lightly.4.Insert gaskets between valve and pipe flanges.5.Make sure the correct alignment of gaskets which are placed on bottom flange bolts between valve and pipe flanges.Figure 1.Installation6Installation&Maintenance Manual6.Stud bolts through the other bolt holes and tighten them lightly.7.Tighten bolts evenly,gradually and alternately in a star pattern as shown below.(See.Fig.2)The ends of all tightened bolts should protrude equally beyond the nuts.8.Raise the line temperature and pressure gradually on test operation Retighten the studbolts/nuts,if needed.Figure2.Flange Bolt Tightening SequenceWarningPersonal injury or system damage may result if the ball valve is installed where service conditions could exceed the limits given in the Specifications.Additionally,physical damage to the ball valve may result in personal injury or property damage due to escaping of accumulated fluid.To avoid such injury and damage,install the ball valve in a safe location.4.OperationThe valve is only intended to block or allow flow through the pipeline.The valve should only be used in either fully open or fully closed position.Do not use this valve to regulate flow by partially opening or partially closing the valve.The valve should not stay in a semi-open or semi-closed state for more than two minutes.Do not use the ball valve in process conditions where the pressure,temperature,media and other technical conditions exceeds the limitations set by the valve’s specification.WarningTo avoid possible personal injury,equipment damage,or leakage due to fluid,make certain the ball valve is installed as instructed in the Installation.7Installation &Maintenance ManualCaution 1.Wear the protective items such as goggle,gloves and working shoes.2.Take safely measures against the toxic,flammable or corrosive fluid.3.Reduce the line pressure to the atmospheric level before retightening packing gland and flange bolts and nuts.4.Operators should take protective measures to prevent direct exposure to the fluid.when the fluid spouts out from flange areas.5.Reduce theline pressuretotheatmosphericlevel,whenthe packing and gaskets arereplaced or bolts and nuts are loosened.Operator should take protective measures toprevent direct exposure to the fluid when the fluid spouts out from valves.6.Do not apply the lubricant to the pipes and valves which handle oxygen.Caution If the ball valve is equipped with test connection port,make sure that it is fully closedbefore pressurizing the valve.1.Check that proper installation is completed and any downstream equipment has beenproperly adjusted.2.Ensure that the pipeline system is free of foreign material before the startup.3.Make sure that the ball valve is fully turned to the open position before allowing fluidto pass through the valve.5.MaintenanceWarning Personal injury,equipment damage,or leakage due to escaping fluid may result if seals are not properly lubricated or maintained.Due to normal part wear or damage that may occur from external sources,ball valve should be inspected and maintained periodically.The frequency of inspection,maintenance,and replacement of parts depend upon the severity of service conditions or the requirements of local,state,and federal regulations.Ball valves that have been disassembled for repair must be tested for proper operationbefore returning it to service.In the maintenance process,take appropriate protective measures,such as wearing protective clothing,oxygenmasks,and gloves.Discharge the residual materials inside thevalve body before doing repair or maintenance.For electric,hydraulic or pneumatic valves,ensure that these lines are shut off before performing maintenance.8Installation &Maintenance ManualTrouble ShootingTrouble Possible Causes Remedial MeasureDisturbed valve operation Foreign objects mayhavechoked up the valve

本手册给客户提供所有相关球阀安装、操作和长期使用维护的信息，所提供的图纸均为标准结构的图纸。
一、 安装前的注意事项1.阀门到达现场后，应仔细检查是否在运输途中受损。
2.在没有完成安装前，应保留阀门的包装和保护的设施。
3.如果阀门的通道以及法兰端面、对焊端等与管路安装有关的地方被裸露，应采取措施加以保护，以防止杂质进入阀门体腔。
4.阀门安装前，应检查和清洗管道，防止杂质如砂子、电焊渣等损坏球体和阀座表面。
5.如果阀门在安装使用前需要存放较长时间，应在阀门裸露表面涂上防锈油，并建议将阀门处于全开位置时存放在干燥和通风的地方，通道两端应上好闷盖保护。
长时间存放后安装使用该阀门，应先进行清洗，并重新试压，合格后投入安装使用。
6.手柄驱动的阀门，手柄指示的位置是阀门开关的标志，当手柄与管道的轴线平行时，阀门为开启，当手柄与管道的轴线垂直时，阀门为关闭。
二、 安装过程中的操作规程1.球阀可在除阀杆方向朝下的任何位置安装，建议安装阀门时将阀杆处于水平位置，严禁阀门倒装！2.阀门不应负载管道的重量。
对管道的支撑将因管道系统的震动造成阀门的变形，阀门可以通过在阀体上安装管道夹和支撑物进行支撑，不应在法兰上固定支撑物（如图7）。
3.不要通过法兰螺栓的调整来纠正管道的不平行。
4.不允许用阀门承载管道的重量来避免管线的扭曲和阻塞。

球阀安装维护手册..
铸钢球阀安装维护手册○本维护手册适用于公称通径不同而又没有特殊需要的同类产品。
○使用前请认真阅读维护手册。
前言本厂生产的软密封铸钢固定球阀，专门设计成密封可靠、使用寿命长、维护简单、维护成本低的一种新型产品。
同时，合适地以及规律的维护则可以最大限度的延长阀门的使用寿命。
目录1.用途和性能规范 (2)2.设计特点 (2)4.设计标准与规范 (4)5.阀门简图 (5)6.主要零件材料 (7)7.存储 (7)8.试验 (7)9.安装调试 (8)10.使用维护 (8)●用途和性能规范本阀门主要适用于天然气、油品等介质，并在管路中作启闭的装置。
具有流阻小、启闭迅速、启闭力矩小、全通径便于清扫管线等特点。
●设计特点a.阀体采用两体侧装或三体侧装结构，阀门内件经过精心选择，确保在各种工况下能可靠的工作。
阀门的壁厚和连接螺栓强度经过严密计算，符合美国标准ASME/ANSI B16.34的要求。
确保阀体的压力等级和连接的稳定性。
b.阀门为固定球结构，采用了具有自润滑衬PTFE的金属轴承，而且阀杆和球体可拆除，球体采用固定轴套支撑。
介质作用在球体上的力不会传递到阀杆上，避免了阀杆径向承受介质力。
球面和阀杆配合表面的光洁度高，减少摩擦力，降低了操作扭矩。
c.阀门处于关闭位置而且球体的一侧受压，阀体中腔内的高压介质（气体或液体）可以通过密封阀座自动往压力低的一端泄放。
d.双截断和排泄（DBB）功能,阀门处在关闭位置而且球体的两侧同时受压，阀体内腔的介质（气体或液体）可以从排泄阀泄放。
e.双活塞效应阀座设计（需要双活塞结构时）：阀座的两侧在压力的作用下均可密封（即双活塞效应），双面密封阀座的特点在于：一旦上游阀座损坏而泄露，介质压力进入阀腔作用在下游侧，将阀座推向球体紧密接触，使下游阀座照样能密封。
这种双活塞效应阀座的球阀，阀体上应装有一个安全卸压阀以防止阀腔内介质因温度变化而产生超压的危险。

球阀安装、使用与维护保养标准手册
一、目的
为加强对公司内常用球阀的安装、使用与维护保养，保证球阀的长周期正常使用，特制订本标准操作手册。
二、适用范围
公司内车间员工。
三、术语解释
球阀：球阀的启闭件是个球体，球体绕阀体中心线作旋转来达到开启、关闭的一种阀门，在管路中主要用来做切断、分配和改变介质的流动方向，它只需要用旋转90度的操作和很小的转动力矩就能关闭严密；适用于低压、小口径管道上用于截断水流和改变水流的分配或需快速启闭的场所。
四、基本流程
五、工作指导 1、球阀安装前准备
1）安装前，确保前后管道同轴无扭曲。
如果是法兰连接，两法兰密封面必须平行。
当管道不能承受球阀的重量时，应在管道下部配有足以支撑管道和阀体的支撑。

2、球阀的安装与使用
1）把球阀装上管线，不能用执行机构作为起重的吊装点，避免造成执行机构及附件的变形或损坏。
2）阀法兰与管线法兰间按管路设计要求装上密封垫。
3）法兰上的螺栓需对称、逐次、均匀拧紧，并抹上黄油保养。

4）对管道与球阀间的法兰结合面进行密封性能检查。
5）开启、关闭球阀数次，灵活无滞涩，其工作正常。
6）安装完成后管道试压，观察法兰处无泄漏。
3、球阀的维护保养
1）阀门只做开关使用，不宜做调节使用；特别不允许在超越温度、压力界线和频繁交变压力工况条件下使用，高温时允许周期性拧紧螺栓以防泄漏，尽力减少热梯度。
2）运行中的阀门要每天检查和维护，严防锈蚀卡阻，要始终保持设备处于

完好状态。
3）填料涵处外漏，检查填料是否压紧。
如用软质填料加注密封方式时，需再加注软质填料至不漏。
4）法兰处外漏，重新均匀拧紧螺栓一直不漏。
5）密封面内漏，检查是否关到位，密封面上是否有异物，在允许情况下打开阀门再关上看是否漏。
6）阀门检修时应重新清洗零件，清除异物，污渣和锈斑。
更换损坏的填料，垫片，修正密封面。
经检修、压力试验合格后方可再次投入使用。
4、球阀的维修
1）必须保证球阀上、下游管道确定已经卸除压力，才能进行拆卸维修操作。
2）拆卸及再装配时必须小心谨慎，防止损伤零件和密封面，尤其是非金属零件，取出O型密封圈时一定要使用专用的工具（尖锥、弯锥、曲锥、装配钩、镊子等）。
3）如果是法兰连接，重新装配时法兰上的螺栓必须对称、逐步、均匀地拧紧。
不可用力过轻，连接不严密，也不可用力过猛，以防脱丝。
4）清洗剂应与球阀中的橡胶件、塑料件、金属件及工作介质（例如燃气）等均相容。
工作介质为燃气时，可用汽油清洗金属零件。
非金属零件可用纯净水或酒精进行清洗。
5）分解下来的单个零件可以用浸洗方式清洗。
尚留有未分解下来的非金属件的金属件可采用干净的细洁的浸渍有清洗剂的绸布（为避免纤维脱落粘附在零件上）擦洗。
清洗时须去除一切粘附在壁面上的油脂、污垢、积胶、灰尘等。
6）非金属零件清洗后应立即从清洗剂中取出，不得长时间浸泡。
7）清洗后需待被洗壁面清洗剂挥发后（可用未浸清洗剂的绸布擦）进行装配，但不得长时间搁置，否则会生锈、被灰尘污染。
再重新装备前必须保证其干燥无污物。
