由于传统的硬杆操纵器无法实现与驾驶室整体倾翻影响到驾驶室的密封性能,无法解决室外粉尘的入侵。
北方奔驰在21世纪初在国内首先采用伸缩硬杆解决了操纵器与驾驶室整体倾翻的技术问题。
到目前重型汽车驾驶室已采用四气囊避震装置,提高驾乘人员的舒适度。
驾驶室避震性能的提高意味着驾驶室与底盘的非对称运动增强,由此造成车辆行驶不良路面时,造成操纵杆急剧晃动变速器自然脱档,凡具有优良避震性能的驾驶室就无法配置硬杆变速操纵系统,淘汰硬杆改为手排软轴操纵系统,软轴操纵解除了硬杆操纵存在的问题,但是长期运行中软轴操纵受到环境影响而有如下几个问题:A、变速操纵的耗力软轴大于硬杆,尤其是使用半年以上,传动效率低、伴随着耗力增大。
B、受到柴油机排气系统温度的侵蚀,严重影响软轴的使用寿命。
伸缩器
伸缩器(补偿器)安装指导由于输送介质温度的高低或周围环境的影响,管道在安装与运转时温度很高,必然引起管道长度和直径相应的变化,当温度差产生额热应力超过管材的允许压力时,使管子处于随时有损坏或危险状态之下,因此必须在管路上安装一定的装置来使管子有伸缩的余地,这就是为热胀冷缩用的伸缩器。
方形伸缩器安装注意事项:1、方形伸缩器组对时,应在平台上或平地上拼接。
2、垂直安装时,如输送介质为液体,应在伸缩器的最低点装疏水装置。
伸缩器两侧的第一支架宜设在距伸缩器弯头的弯曲起点0.5~1m处,支架的活动支架,不得设导向支架。
3、安装伸缩器为了减少热应力和提高热补偿能力,必须对伸缩器进行预拉伸,输送热介质的管道需冷拉,输送冷介质需冷压。
管道的预拉或预压应在两个固定支架之间的管道安装完毕并与固定支架连接牢固以后进行,预拉伸或预压缩的焊口离开伸缩器的起弯点应大于2mm,并应将伸缩器两臂同时拉伸或压缩。
4、管道支段设置伸缩器的最大距离。
5、方形伸缩器的预拉伸。
方形伸缩器安装前应进行预拉伸。
拉伸的方法,一种是用千斤顶将方形伸缩器顶开,另一种是常用的拉管器法。
在拉伸前,先将两端的固定支架焊牢,伸缩器两端的直管与连接管的末端之间应预留一定的间隙,其间隙值应等于设计补偿量的1/4。
然后用拉管器安装在两个待焊的接口上,收紧拉管器螺栓,拉开伸缩器直到管子接口对齐,并把它点焊好方可拆除拉伸器。
波形伸缩器:波形伸缩器因其强度较弱,补偿能力小,轴向推力大,适用于管径大于150mm以上及压力低于0.6MPa的管道。
波形伸缩器由钢板制成,其外形如下:波形伸缩器安装注意事项:1、波形伸缩器安装前应检查其各部尺寸是否符合要求,波形伸缩器表面不得有裂纹、凹凸、轧痕等缺陷。
并按设计规定压力,进行水压试验,合格后方可安装。
2、安装时,应注意伸缩器的方向。
伸缩器内的衬套外壳焊接的一端,应朝向坡度的上方,以防冷凝水大量流到波形皱折的凹槽中。
3、伸缩器的拉伸和压缩,应在平地上分次逐渐进行,拉伸或压缩应按照施工图规定数值进行,在待接管道上留出伸缩器的位置,再用拉管器将伸缩器拉长或缩短后,与管子连接。

In order to maintain this product warranty, Buyer must give written notice to Seller’s Field Service Supervisor prior to any work being performed.IN CONSIDERATION OF THE FOREGOING, SELLER EXCLUDES ALL OTHER EXPRESS OR IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.Seller does not warrant water operated metallic cylinders against damage caused by corrosion, electrolysis or mineral deposits. In no event shall warranty include valve removal or reinstallation.Read all applicable directions and instructions prior to any maintenance, troubleshooting orinstallationWARNINGWARNINGFUNCTIONAL DESCRIPTION 4INSTALLATION 5OPERATION 9MAINTENANCE 11 TROUBLESHOOTING 12CONTACTING PRATT 13PRODUCT DRAWINGS 14BF Series Butter f ly Valv esFunctional DescriptionRound butterfly valve disc rotates 1/4 turn to provide tight shut of f in air or water pipelines. The valves can be used to regulate flow rate by positioning the disc between 10 and 90 degrees open .Manually Operated ValveManually operated butterfly valves are powered with gear actuators, which convert multiple handwheel,chainwheel or handle input turns into 1/4 turn valve operation. The travel of the valve disc is limited by physical stops in the actuator housing.Forcing the handwheel, chainwheel or nut against the stops will not provide tighter shutoff of the valve and may damage the actuator. Only actuator adjustments will affect valve shutoff.Motor Operated ValveMotor operated butterfly valves are powered with gear actuators, which convert multiple motor input turns into 1/4 turn valve operation. The travel of the valve disc is limited by limit switches in the motor housing and physical stops in the actuator housing. Valve shutoff is affected by limit switch and physical stop settings.Improperly set limit switches and/or physical stops may damage the motor and/or actuator.Cylinder Operated ValveHydraulically operated butterfly valves are powered with a gear box and double acting cylinde r . The linear stroke of the cylinder is converted to 1/4 turn operation by the gear box. Auxiliary controls are provided todirect hydraulic power to the cylinder and to control the operating speed of the cylinder.WARNINGWARNINGBF Series Butter f ly Valv esINSTALLATIONGENERALValves are a significant component of any piping system. Failure due to faulty installation, improper operation or maintenance in such systems could result in damage, down time and costly repairs. In buried underground installations, problems or malfunctions can result in extensive, costly unearthing operations to correct the problem. Many problems with valves can be traced to improper installation, operation, or maintenance procedures.UNLOADINGInspect valves on receipt for damage in shipment and conformance with quantity and description in the shipping notice and order. Carefully unload all valves to the ground without dropping using fork trucks or slings under skids. Do not lift valves with slings or chain around operating shaft, actuator, or through waterway. Instead, lift valves with eye bolts or rods through flange holesSTORAGEWhenever practical, store valves indoors. If not, protect valves and actuators from weather and accumulation of water, dirt, rocks and debris. When valves fitted with power actuators and controls are stored, energize electric actuator or otherwise protect electrical control equipment to prevent corrosion of electrical contacts due to condensation resulting from temperature variation. Do not expose rubber seats to sunlight or ozone for any extended period. Valves should be stored with the valve disc or closure member slightly open. INSPECTION PRIOR TO INSTALLATIONMake sure flange faces and joint sealing surfaces, body seats and disc seats are clean. Check bolting attaching actuator to valve for loosening in transit and handling. If loose, tighten firml y. Open and close valve to make sure it operates properly and that stops or limit switches are correctly set so that the valve seats fully. Check that valve rotation direction is correct and close valve before installing.INSTALLATIONThe following items must be performed during installation to ensure proper function.•Carefully place valves into position avoiding contact or impact with other equipment, vault walls or trench walls.BF Series Butter f ly Valv es•Valves are to be installed in accordance with the General Arrangement Drawings furnished for the order.•Foreign material in a valve can damage the rubber seat when valves are operated. Be sure valve interiors and adjacent piping are clear of foreign material prior to mating valve to pipe joint.•Prepare pipe ends and install valves in accordance with the pipe manufacturer’s instructions for the joint used. Do not deflect pipe/valve joint. Do not use valve and jack to pull pipe into alignment•In plant piping, install so as to minimize bending of valve connection with pipe loading.•Make sure valve disc, when opened, will not contact pipe port. This is especially necessary on pipe with lin-ings. Check manufacturer for minimum pipe I.D. required for clearance.Valve disc without actuator may open or close at any time and cause injury to persons or damage to valve and other property. The shaft/disc clamping device when furnished is intended for temporary use during shipping, handling and valve installation only. Do not subject valve to flow conditions before actuator is mounted and tested for performance and clamping device is removed.Buried valves installed with valve boxes must be so installed that the valve box does not transmit shock or stress to the valve actuator as a result of shifting soil or traffic loadWhen valves are installed in vaults, the vault design must provide space for valve/actuator repair. The valve operating nut should be accessible from the top opening of the vault with a tee wrench....Series valves are bi-directional and will control flow equally well in either direction. For the best results in slurry service, position the valve so that the valve stem is in the horizontal position and the lower disc edge opens downstream. This will ensure a self flushing effect extending the life of the valve.The valve should not be placed too close to other valves, elbows, etc. as its operational performance may be affected. It is recommended that the valve have, at a minimum, six pipe diameters upstream and four pipediameters downstream between int and any other valves, elbows, etc. in the system.WARNINGBF Series Butter f ly Valv esInstallation Between Pre Existing Flanges1.Observe that the disc sealing edge is in line with the parallel flats (or keyway) on the stem. Rotate the ste m clockwise to position the disc within the body at least 0.375in. away from the body face.2.S pr ead the flanges to exceed the valves face to face dimension by 0.19in. before placing the valve in position to prevent distortion and/or damage to the seating face of the valve.3.Center the valve body between t he flanges and span the valve body with all flange bolts possible.Turn the disc to the fully open position.4.While gradually removing the flange spreaders, center the valve to the flanges and tighten the bolts h alf tight. Slowly close the valve to check for adequate disc clearance.5.Return the disc to the fully open position and cross-tighten all bolting. Bolt tightening sequence should be per the following table and diagram.Bolt TorquesFlange Size Recommended Min. BoltTorque (Pound Force Inches)Flange Size Recommended Min.

Test pressure may cause leakage past the rubber seat or damage to the valve.In order to prevent time lost in searching for leaks, it is recommended that excavations for buried valves not be back-filled until after hydrostatic pressure tests have been made .Seat leakage can occur due to foreign material in the line. If this occurs, open valve 5 – 10 degrees to get high velocity flushing action. Close and repeat several times to clear seats for tight shut o f f.Seat leakage can occur due to rotational shift in position of the disc with relation to the body seat. Readjust closing stop in accordance with manufacturer’s instructions.Do not permit use and operation of any valve at pressure above the rated pressure of the valve.Do not exceed 300 ft-lb input torque on actuators with wrench nuts, 200 lb. rim pull input torque for handwheels or chainwheels. If portable auxiliary actuators are used, size the actuator or use a torque limiting device to prevent application of torque exceeding 300 ft-lbs. If an oversize portable auxiliary actuator with no means of limiting torque is used, stop the actuator before valve is fully opened or closed against stops and complete the operation manually. Be sure to check portable auxiliary actuator directional switch against direction indicated on wrench nut, handwheel or records before applying opening and closing torque.If a valve is stuck in some intermediate position between open and closed, check first for jamming in the actuator. If nothing is found, the interference is inside the valve. In this case, do not attempt to force the disc open or closed since excessive torque in this position can severely damage internal parts.MANUAL ACTUATOR FUNCTION AND USE:The manually operated butterfly valves are operated by rotating the handwheel, chainwheel, or nut.The actuator is equipped with gearing to convert the many turns into 1/4 turn operation. Inside actuator stops that limit the travel of the valve are pre-set at the factory. Forcing the handwheel, chainwheel, or nut will not cause the valve to shut off any tighter and may cause damage to the gearing.CYLINDER ACTUATOR FUNCTION AND USE:The cylinder operated butterfly valves are operated automatically by directing hydraulic pressure to either side of the power cylinder. Solenoid valves are used to direct the fluid to the cylinder ports based on electrical power signals. In cylinder actuators, the travel stops are in the cylinder so that full hydraulic pressure can be held on the cylinder at either end of travel.MOTOR ACTUATOR FUNCTION AND USE:The motor actuator is designed to open and close the valve through its one quarter turn of rotation. It contains gearing so that hundreds of turns of the motor or handwheel will slowly move the valve from open to close position or vice versa. Electrical controls are included in the motor actuator for local electrical control.The output motion of the actuator is limited to about 100 degrees of output rotation by mechanical stops inthe gearing. These are factory set and should not need adjustment. The actual positioning of the valve disc will be done by limit switches in the motor actuator. The switches are also set at the factory but adjustmentis sometimes required if the motor unit is installed on a separate mounting base or floorstand. Detailed procedures are given in the motor manual if adjustment is needed for the mechanical stops or the limitswitches. The wiring and power requirements are given on wiring diagrams included in this instruction manual.BF Series Butter f ly Valv esFluids exposed to freezing temperatures may cause valve to fail resulting in injury to persons or dam-age to valves and other property. Do not use in applications that are exposed to freezing temperatures unless sufficient flow is maintained through the valve to prevent freezing, or other protection is pro -vided .IMPORTANT SAFETY NOTICEAll persons who will install, operate or adjust this equipment must read the instructions and drawings carefully. Injury and property damage may occur from improper use. It is understood that this equipment will be installed by individuals with knowledge and skills in electrical equipment. The manufacturer cannot be responsible for the misuse of this information or equipment, nor can it assumeany resultant liability.WARNINGWARNINGBF Series Butter f ly Valv esMAINTENANCEMaintenance of valves by owner is generally limited to actuators and shaft seals. In some instances, valve de-sign permits field adjustment of seat when leakage occurs. Unless the owner has skilled personnel and proper equipment, any major rework will require removal of the valve from the line. Depending on condition, valve may require return to the manufacturer.ANNUAL MAINTENANCE1.Cycle valve to verify operation and no interference in line.2.Close valve and check for leakage. If leakage is detected, check actuator stops to verify that disc is fully closed. If leakage persists, remove valve to inspect seat. Refer to the service procedures section of this manual for information regarding adjustment or replacement of seat.3.Check flange connections for leakage. Tighten bolts accordingly.4.Check top trunnion area for shaft leakage. If leakage is detected, replace valve o-rings in top cover.5.If Access to the line is possible, then removal of scale that may interfere with disc travel is suggested.The seat should be inspected for wear and the screws should be tight. NOTE: LUBRICATION IS NOT REQUIRED.Removal of actuator from valve shaft will cause disc to rotate, striking persons or objects in the disc path, causing injury to persons and damage to valve. Block or lock disc before removing actuator.Typical maintenance would be shaft o-ring replacement and actuator adjustment. O-ring leakage, broken parts and difficult operation should be discussed with the factory before valve repairs are attempted.Stop line flow and isolate from line pressure prior to performing any corrective maintenanceAfter completing repair, cycle valve through one complete operating cycle and after line pressure has beenrestored, inspect for leakage.WARNINGBF Series Butter f ly Valv esTroubleshooting GuideProblemCausesRemediesHigh Torque•Pinched seats•Flange bolts are not evenlytorqued•Over-torqued boltsLoosen the flange bolts.
