Contents1.Introduction2.Pre-Inspection3.Installation4.Operation5.Maintenance6.Disassembly/Reassembly7.Storage8.Packing9.Transport21-2Personnel qualification 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

avoid personal injury resulting from sudden release of pressure,isolate the ball valve from all pressure and cautiously release trapped pressure inside the valve chamber before attempting disassembly.Ensure that the middle chamber of the valve is fully depressurized before dismantling ormaintaining the valve.Pressure inside the pipe may be released,but the middle chambermay still have residual pressure.Open and close the valve several times to ensure that the pressure in the valve is completely released.If the media conveyed by the valve is toxic,inflammable,or explosive,make sure that there are no residual media left in the valveespecially in the middle chamber.Flush the valve with water or the appropriate cleaningsolvent to ensure the complete removal of the residual media.Open and close the valveseveral times while flushing the valve.Observe proper protective measures when dismantling the valve.If the media conveyed by the valve is toxic,inflammable,or explosive,always wear personal protective equipment to avoid any injury or accident.Keep the working site away from fire,sparks,or ignitionespecially if the media is combustible.To disassemble the valve,start disassembling with the last part as outlined in the assembly section.Place the dismantled parts on a soft mat.Do not allow it to have direct contactwith the ground.Mark the dismantled parts correctly to avoid confusion during the assembly.Do not dropor apply excessive force to the valve and its related parts to avoid damage or deformation of the components.if it will not be used for a long time,store the dismantled parts in asafe and dry area in order to protect it and prevent the formation of rust.6-1.Separation of Valve from the Pipe LineTo repair leaking valve,the valve must be removed from pipe line and then parts must be separated as below-Before removing the valve from the line,make sure that the line has been fully depressurized.-Drain all mediums from the pipe.-Remove the parts and remove the valve from the pipe.-Once the valve is removed,appropriate isolation of the pipe ends should be undertaken by the operator/contractor to prevent the creation of a combustible mixture where possible,and to prevent the introduction of dirt and debris into the system.-Mark the location of each part of valve and pipe in order to be installed at same places where they were.11Installation &Maintenance Manual6-2.Disassembly (See.Fig.4)-Unfasten the yoke bolt and then remove operator from body.-Refer to the appropriate operator instruction manual for actuator

固定球阀结构说明书

固定球阀结构说明书嘿,朋友!想象一下这样一个场景,在一个热火朝天的工厂车间里,各种机器轰鸣作响,工人们忙碌地穿梭其中。

而在这一片繁忙之中,有一个小小的但却至关重要的部件——固定球阀,正默默地发挥着它的巨大作用。

这固定球阀啊,从外表看,它就像一个被精心打造的小堡垒。

它主要由阀体、球体、阀杆、阀座和密封件等部分组成。

先说这阀体,它就像是整个球阀的“身躯”,为其他部件提供了坚实的“家”。

阀体的材质那可得讲究,得能承受住各种压力和温度的考验,不然稍微一折腾就“罢工”可不行。

再瞧瞧这球体,它可是整个球阀的核心“人物”。

它就像一个灵活的“舞者”,在阀体内自由转动,控制着流体的通断。

当需要关闭阀门时,它就乖乖地与阀座紧密贴合,把流体通道堵得严严实实,一滴水、一丝气都别想溜过去。

而阀杆呢,就像是连接球体和外部操作装置的“桥梁”。

通过它,我们可以轻松地控制球体的转动。

想象一下,你轻轻转动手轮,阀杆就带动球体开始工作,是不是有种掌控一切的感觉?阀座也不容小觑,它就像球体的“亲密伙伴”,时刻陪伴在球体身边,为球体提供良好的密封性能。

它们之间的配合默契程度,直接决定了球阀的密封效果。

密封件则像是一层“保护罩”,进一步增强了球阀的密封性,确保不会有任何泄漏的情况发生。

这固定球阀在工作时,那可真是一丝不苟。

当需要截断流体时,球体迅速就位,紧紧地与阀座相拥,仿佛在说:“别想从我们这里过去!”而当需要让流体通过时,球体又灵活地转动,给流体让出一条通畅的道路,就像在热情地招呼:“快请,快请!”在我们的日常生活中,固定球阀的身影也是无处不在。

比如家里的水管总阀,它就是一个小型的固定球阀,默默地守护着我们的用水安全。

还有那些大型的工业管道系统,固定球阀更是发挥着不可替代的作用,保障着生产的顺利进行。

你想想,如果没有这固定球阀,管道里的水啊、气啊、油啊,岂不是要乱了套?到处泄漏,那场面简直不敢想象!所以说啊,这固定球阀虽然看似不起眼,但却是实实在在的“幕后英雄”。

球阀说明书球阀问世于20世纪50年代,随着科学技术的飞速发展,生产工艺及产品结构的的不断改进,在短短的40年时间里,已迅速发展成为一种主要的阀类。

在西方国家工业发达的国家,球阀的使用正在逐年不断的上升,在我国,球阀被广泛的应用在石油炼制、长输管线、化工、造纸、制药、水利、电力、市政、钢铁等行业,在国民经济中占有举足轻重的地位。

球阀主要用于截断或接通管路中的介质,亦可用于流体的调节与控制,其中本公司生产的硬密封V型球阀其V型球芯与堆焊硬质合金的金属阀座之间具有很强的剪切力,特别适用于含纤维、微小固体颗料等介质。

而多通球阀在管道上不仅可灵活控制介质的合流、分流、及流向的切换,同时也可关闭任一通道而使另外两个通道相连。

球阀的结构特点①流体阻力小,球阀是所有阀类中流体阻力最小的一种,即使是缩径球阀,其流体阻力也相当小。

②开关迅速、方便,只要阀杆转动90o,球阀就完成了全开或全关动作,很容易实现快速启闭。

③阀座密封性能好。

大多数球阀的密封圈都采用聚四乙烯等弹性材料制造,软密封结构易于保证启封,而且球阀的密封力随着介质压力的增高而增大。

④阀杆密封可靠。

球阀启闭时阀杆只作旋转运动而不作升降运动,阀杆的填料密封不易破坏,且阀杆倒密封的密封力随着介质压力的增高而增大。

⑤由于聚四氟乙烯等材料具有良好的自润滑性,与球体的摩擦损小,故球阀的使用寿命长。

⑥可配置气动、电动、液动等多种驱动机构,实现远距离控制和自动化操作。

⑦阀体内通道平整光滑,可以输送粘性流体、浆液以及固体颗粒。

⑧安装简便,能以任意方向安装于管道中的任意部位。

产品的主要结构、功能一、对夹系列球阀对夹球阀及对夹保温夹套球阀是我厂新开发的产品,与普通产品相比,具有结构长度短、重量轻、安装方便、节省材料等显著的优点。

(如图一、图二)二、全通径系列及缩径系列我公司球阀一般设有全通径及缩径两个系列,以满足不同工况的需要。

全通径球阀的通道内径与管线内径一致,流体阻力最小,并便于管道清扫。

而缩径系列球阀的重量只有相同口径全通径球阀的70%左右,能有效的降低成本及价格,而其流体阻力只有相同口径截止阀的1/7左右,故缩径球阀在国外得到了较广泛的使用。

如右图三、阀座的可靠密封1、浮动球阀采用双斜面弹性密封圈或V形槽弹性密封圈结构设计。

有效的降低了球体与密封圈之间的磨擦系数,减少了操作力矩。

当介质压力较小时,密封圈与球体接触面积较小,故有较大的密封比压,确保可靠密封。

介质压力较大时,密封圈与球体接触面积增大,故密封圈能承受较大的介质推力而不会损坏。

(如右图)2、当介质的冲刷力较大时,特别设计的阀座防冲刷结构能有效的防止介质冲刷,确保封圈的使用寿命。

如(图四)3、对于工作压力很低的球阀,考虑到介质压力不能确保阀座可靠密封,而预紧力长期使用后又会衰减,故对于低压、超低压或真空工况用球阀,采用弹簧加载的阀座密封结构,能确保球阀长期可靠的密封。

如(图五)4、固定球阀根据压力大小、可选择不同的密封形式:A:进口端密封B:出口端密封C:进、出口端双向密封。

(见下图)由于d1、d2的面积差在上游介质的压力作用下,形成的活塞效应,使阀座与球体紧密接触而密封。

由于d1、d2的面积差在阀体中腔介质的压力作用下,形成的活塞效应,使阀座与球体紧密接触而密封。

由于d1>d2>d3在d1、d2、d3之间的面积差,在受到上游介质与中腔介质的压力作用下,形成的活塞效应,使阀座与球体紧密接触而密封。

四、防静电结构根据用户的要求,球阀可设计防静电结构。

采用弹簧一柱式塞式静电导出装置,即在球体与阀杆、阀杆与阀体之间设置导电弹簧,使球体与阀杆及阀杆与阀体之间形成静电通道,达到清除静电的目的。

避免静电打火点燃易燃介质,确保系统安全。

(图七)五、启闭灵活的操作机构在有相对运动的部位(如阀杆与阀体、阀杆与填料压套),设置了摩擦系数小的增强聚四氟乙烯衬套,不仅减小了操作力矩,使启闭更加灵活,而且避免了金属部件之间的擦伤。

如(图八)六、阀杆防冲飞及倒密封结构阀杆采用下装式、设置带有密封垫片的倒密封结构,倒密封的密封力随阀腔介质压力的增高而增大,从而确保阀杆的密封效果。

当阀腔异常升压时,阀杆不会被冲出,填料采用设计合理的V型结构,能将阀腔内部的介质力及外部压盖的锁紧力有效的转化成阀杆的密封力。

如(图九、图十)七、耐火结构根据用户的需要,球阀可设计成耐火结构。

当万一发生火灾而使聚四乙烯等软密封圈烧损时,球阀仍然能够可靠操作并具有良好的密封性能,以防止火灾的扩大。

如(图十一)八、自动泄压结构当滞留在阀门中腔的液体介质由于温度升高而气化,从而中腔压力异常升高时,中腔介质能依靠本身的推力推动阀座而自动泄压,从而确保阀体的安全。

如(图十二)九、辅助密封结构根据用户的需要,球阀的阀座及阀杆的密封部位,可加注脂阀,当密封部位因擦伤而引起泄漏时,通过注脂阀注入密封脂中,可起瞬时密封作用。

如(图十三)十、V型球阀本厂开发了硬密封V型球阀,其V型球芯与堆焊硬质合金的金属阀座之间具有很强的剪切力,特别适用于含纤维、微小固体颗粒、料浆等介质。

图(图十四)十一、中、高温球阀的阀座密封结构采用对位聚苯密封圈可用于300℃的温度而采用全屏密封耐高温组合材料结构设计的球阀可用于更高的温度。

十二、低温球阀为了防止低温工况下阀杆填料密封的失效,低温球阀采用长颈结构设计。

阀座采用具有自动泄压功能的结构设计,以防止阀门中腔介质由于升温而出现的异常升压。

严格控制材料的化学成分及低温冲击韧性等力学性能指标。

十三、球阀的设计制造标准十四、球阀的试验压力BQ71F对夹保温球阀BQ971F气动对夹保温球阀制造标准Manufacture Standard: GB 口径Caliber(mm):15~150 材质Material:WCB、304、316、316L 压力Pressure(MPa):1.0、1.6、2.5 温度Temperature(℃):-20~+300三通内螺纹电动/气动球阀球阀是用带有圆形通道的球体作启闭件,球体随阀杆转动实现启闭动作的阀门,其启闭件是一个有孔的球体,绕垂直于通道的轴线旋转,从而达到启闭通道的目的。
