手动球阀使用说明
球阀使用说明书 Q41F 浮动式球阀球 阀 (Ball Valve)球阀是由旋塞演变而来的，它的启闭件为一个球体，利用球体绕阀杆的轴线旋转90度实现开启和关闭的目的。
球阀在管道上主要用于切断、分配和改变介质流动方向，设计成V 形开口的球阀还具有良好的流量调节功能。
球阀不仅结构简单，密封性好，而且在一定的公称通径范围内体积较、重量轻、材料耗阀门品种之一。
特别是在美、日、德、法、意、西、英等工业发达国家，球阀的使用非常广泛，使用品种和数量仍在继续扩大，并向高温、高压、大口径、高密封性、长寿命、优良的调节性能以及一阀多功能方向发展，其可靠性及其他性能指标均达到较高水平，并已部分取代闸阀、截止阀、节流阀。
随着球阀的技术进步，在可以预见的短时间内，特别是在石油天然气管线上、炼油裂解装置上以及核工业上将有更广泛的应用。
此外，在其他工业中的大中型口径、中低压力领域，球阀也将会成为主导的阀门类型之一。

（2） 因在工作时不会卡住（在无润滑剂时），故能可靠地应用于腐蚀性介质和低沸点液体中。
（3） 在较大的压力和温度范围内，能实现完全密封。
（4） 可实现快速启闭，某些结构的启闭时间仅为0.05~0.1s，以保证能用于试验台的自动化系统中。
快速启闭阀门时，操作无冲击。
（5） 球形关闭件能在边界位置上自动定位。
（6） 工作介质在双面上密封可靠。
（7） 在全开和全闭时，球体和阀座的密封面与介质隔离，因此高速通过阀门的介质不会引起密封面的侵蚀。
（8） 结构紧凑、重量轻，可以认为它是用于低温介质系统的最合理的阀门结构。
（9） 阀体对称，尤其是焊接阀体结构，能很好地承受来自管道的应力。

Read these instructionsthoroughly!- Always use the necessary protective equipment and comply with applicable safety directives whenworking with hazardous or hot/cold medium.- Never operate a valve without fi rst ensuring that there is no risk of crush injuries. The risk is highest withautomatic valves.- Take necessary safety precautions to prevent unintentional manoeuvre - i.e to atmosphere.- Never dismantle a valve or part of a valve without ensuring that the line is free of pressure and anycontent.- Ball valves must always be dismantled in semi-open position to avoid trapping pressure and medium.- Always check that the valve type and material is suitable for its intended use. This applies especially to highly oxidising and corrosive medium. Observe also the risk of erosion and explosion as well as decaying medium. If in doubt, always request a writtenrecommendation from NAF AB.1. GeneralThis instruction is valid for NAF-Trunnball ball valves in accordance with catalogue sheet Fk 41.66 GB.2. LiftingAll lifting must be made inthe valve itself and not in theactuator. The joint betweenthe valve and the actuatoris designed principally forcarrying the operating torqueand the deadweight of theactuator (see Fig. 1).alve 3. Receiving inspectionAll valves leaving our works are inspected and testedin accordance with the relevant requirements or in accordance with the special conditions specifi ed by the customer. Valves equipped with actuators are subject to functional testing and are adjusted in such a manner that every unit is completely ready for direct installation inthe pipework. However, in view of damage that may have occurred during transport, it is advisable that receiving inspection is performed, if possible.We would suggest the following inspection procedure:- Check that the valve delivered is correct interms of type, size, equipment, etc.- Examine the valve, actuator and valve positioner regarding possible damages.4. InstallationBefore installing the valve, ensure that the pipework is free from impurities, that the pipe ends between which the valve is to be installed are parallel and are correctly aligned, and that the distance between the pipe ends corresponds to the valve length, including gaskets. The valve must not be used for drawing together or aligning incorrectly run pipes as this will cause needless loads on the valve and pipe which may lead to diffi cult damages during operation. See Fig. 2.Wrong installation Correct installation Fig. 2. Ensure that the pipe ends align and have thecorrect distanceNAF-Trunnball valves can be installed in any position and with optional fl ow direction.However, we recommend that, if installed in a horizontal run of pipe, the valve should be mounted with the stem pointing vertically upwards. If the valve is installed in a vertical run of pipe, the body half (2) according to fi g. 3 should be at the top to enable the ball and the seat ring to be replaced without the need for removing the valve from the pipework.The pipes should be supported on each side of the valve, in order to relieve the valve of loads and avoid vibrations.Locate the valve so that it will be easily accessible for inspection and service, particularly if the valve is equipped with an actuator and a valve positioner.5. Flange GasketsGaskets with sizes according to ANSI B16.5 1988, Table E1 Figure E2, SS 359 or DIN 2690 are recommended.6. Starting upBefore starting up, fl ush the pipework - with all valvesin the open position - so that any impurities that may damage the sealing surfaces of the valve and impede its operation will be fl ushed away.See also Fi 41.82 - Instruction Manual for NAF valve positioner giving useful hints for starting up. 7.

Shut off all compressed air connections and isolate all electrical connections to the actuator.4. Disconnect all compressed air lines and electric cables connected to the actuator.5. Loosen the fl ange joint between the valve and the pipework. Then lift out the valve. Don’t use the actuator for lifting. Apply all lifting forces tothe valve itself and not to the actuator - Fig. 1.N.B . In certain applications, the pipe can be discon- nected from one side of the valve, and the body half (2) - Fig. 3 - can be removed, without the need for removing the whole valve from the pipework.6. Mark the relative positions of the body halves by centre-punching before the dismounting, since the pattern of the holes drilled in the valvefl ange and pipe fl ange may vary.Fig. 4. Lifting the ball with the valve in closed posi- tion - here with the valve on a work bench. It can also be done with mounted actuator and the body (1) mounted in the pipework.8. MaintenanceMany valves are installed in such locations that their performance is of decisive importance to the entire process. Such valves should be inspected regularly and any faults should immediately be corrected.8.1 To remove the valve from the pipeworkNo special tools are needed for the inspection and maintenance.1. Ensure that the recommended spare parts and gaskets for the pipe fl anges are available.2. Close the valve. Before dismounting the valve, make certain that it is completely empty . Operate the valve several times between the open and closed positions to ensure that the space between the valve body and ball is not under pressure.Caution! The liquid in the valve may be harmful.8.2 To inspect and replace the ball and seatrings 1. The actuator does not need to be removed for replacing the seatring and ball.2. Operate the valve to make certain that it is completely empty . Close the valve.3. Remove the bodyhalf (2).4. Remove the ball and the trunnion plates - easy to do when the valve is in closed position.5. Remove the trunnion plates and the metaloplast bearing from the bearing journal of the ball.6. Carefully inspect the ball and the seatrings.7. Clean all parts carefully. First use hot water and then, if necessary, some degreasing compound. Do not scrape any machined surfaces with hard tools.8.3 Valves with seatrings in PTFE1. To ensure good tightness of the valve, change the seatrings, wave springs and sealings if they are worn or damaged.2. Mount the wave spring and sealing ring (pos 24 and 25) behind the seatring (pos 20).3. Inspect the ball. Minor damage to the sealing surface can be removed by polishing with fi ne emery cloth. If the ball has major damages, it must be replaced to ensure satisfactory tightness.4. Change sealing ring (14) between the two body- halves.5. Change the metaloplast bearing in the trunnion plates.6. Mount the bearing plates on the bearing journal of the ball.7. Coat the ball with Molycote U. If the valve is intended for service in an oxygen system, the ball can be coa- ted with silicone grease, which is approved for oxygen applications.8. Lubricate all stainless steel bolts with suitable grease, i.e. Crane Packings’s Thread-Grade or Gleitmo 600.9. Mount the ball and the bearing cage in the bodyhalf (1) and then the upper bodyhalf (2). Make sure that the centrepunch marks made according to section 8.1 item 6 are lined up. Tighten the bolted joint of the two bodyhalves alternately in several stages and tighten them fi nally as per the table below.10. Torque for tightning of the bolted joint:11.Operate the valve between closed and open positions.12. If possible, pressure test the valve with water to check its tightness - Fig. 5. Make sure that the c avities of the valve are properly fi lled with water before the pressure testing. The valve should be pressure tested as follows: Open valve: PN x 1,5Closed valve: Max dp x 1,1Bolt Torque NMBolt Torque NmM1276UNC 1/2”89M16187UNC 5/8”175M20364UNC 3/4”308M24629UNC 7/8”493UNC 1”73768.4 Valves with chromium-plated ball and seatrings in alloy 61. Check the sealing surfaces of the seatrings.A groove on the inside of the ring facilitates with- drawal. Minor damage to the rings can be polished with fi ne emery cloth. Check the rings on a face plate to ensure that they are perfectly fl at. Do not lap the rings and the chromium-plated ball together. Change the rings if they are severely damaged.2. Inspect the sealing surface of the ball. Minor damage may be polished with fi ne emery cloth. If the existing ball must be used for a furtherperiod of time, remove all sharp edges, dents and irregularities with a fi ne fi le or emery cloth. Check the circularity of the ball. The tolerance is 0.04 mm. If the ball is seriously damaged, it must be replaced.3. Mount the wave spring and the sealing ring (24 and 25) behind the seatring.4. Change the sealing ring (14) between the bodyhalves.5. Lubricate the ball with a suitable grease, such as Molykote U.6. Continue assembling the valve as described in section 8.3 item 8-12.Valve open Valve closedSealing fl angeWaterFig. 5.

Lubricate a new packing box (11) with silicone grease before you press it down into the body. Note that the broadest of the 5 rings should be on top, see fi g 3 on page 3.11. Mount the stem by pressing if from the inside of the body and out.12. Mount the supporting ring (7) in the anti-friction washer (13), lubricate a new o-ring (26) with silicone grease and mount it in the anti-friction washer. Mount the anti-friction washer with the o-ring downwards against the valve.13. Mount the remaining parts in reverse order from item 5 to 1.8.5 Valves with ball and seatrings in alloy 6.1. The instructions for these valves are the same as those in section 8.4 above.2. If the sealing surfaces are damaged, we recom- mend that the valve is returned to NAF for repair. This applies especially if the ball must be ground before l apping. Assemble the valve before dispat- ching it to NAF.3. The ball and seat rings can be temporarily renova- ted by lapping them together. This can be done manually with a compound with grit size 200. Take great care to ensure that the ball and seat rings do not become oval.4. Balls in alloy 6 must be carefully cleaned andlubricated before they are mounted. Use a suitable solvent for cleaning. Then lubricate the ball with silicone grease, such as Molykote Dow Corning FS3452. The coat of grease must be very thin. Then polish the ball with chamois leather or apiece of soft cloth.WaterWat8.7 Change of the upper stem sealing with o-rings(DN450-DN800) i.e. type 898295-XXXXChange the upper o-ring (32) if the stem sealing is leaking.

The actuator may be mountedeither in line with the connected pipes or transversely to them. For mounting in line with the connectedpipes an intermediary plate is required2. Ensure that both the valve and the actuator are inthe closed position before mounting the actuator.The valve is in the closed position when thekeyway on the stem is in the direction of fl ow.(An actuator which uses compressed air to closethe valve and a return spring to open the valveshould be mounted with the actuator and valve in theopen position.)N.B. The direction of closure must always beclockwise, as viewed from the actuator.3. Before fi tting a new actuator, check that theactuator slides easily onto the stem when thekeys are not fi tted. Check also that the keys fi tfreely into the keyways in the hollow shaft of theactuator. Deburr if necessary. Lubricate the hollowshaft of the actuator and push it in over thethreaded sleeve. Mount the actuator onto the stem.Mount the bolts and nuts, and tighten them.4. Check the function and check that the end stopshave been correctly preset. If necessary, makeadjustments.If any accessories such as valve positioner orlimit switches should be mounted, please see thecorresponding manufacturer’s instructions forinstallation and adjustment.7NAF ABSE-581 87 Linköping Telephone +46 13 31 61 00Facsimile +46 13 13 60 54e-mail info@naf.seWebsite: www.naf.seISO 9001 Certifi edWe reserve the right to design modifi cationswithout prior notice8。

6 Operation
The valve can be manually operated by using the handle for manually operated valves or motor-operated by the electric actuator for motor operated valves or pneumatic operated by pneumatic actuator for pneumatic operated valves. The valve open or closes by turning the ball. Clockwise turning to 90ºresults in valve open.
6.1 The manually operated valve is opened when the handle and the position mark on stem end are parallel to pipeline. When that is perpendicular to the pipeline, the valve is closed.
6.2 For motor/pneumatic operated valves, valve open/close is indicated by the positioner on the electric/pneumatic actuator.
7 Storage, maintenance, installation and service
7.1 The valve should be stored in dry room with good ventilation. Valve ends should be covered.
7.2 For valve stored for a long period of time, regular checkup is required to ensure that the valves are in good conditions. Foreign particles should be removed and special care should be taken to keep the valve seat sealing surface clean and prevent any damage of sealing surface.
7.3 Check the conformance of valve identification to the service requirements prior to installation.
7.4 Check the cleanness of the valve cavity and sealing surface and sealing surface and wipe off any dirt with white cloth prior to installation.
7.5 Before installation, the tightness of packing should be checked to ensure that sealing is secured without affecting the turning of stem.
7.6 The valve shall be in full open position when conducting system or pip line pressure test after the valve installation.
7.7 Ball valve shall be in full open or full close position while in service. partial opening for controlling the flow is not allowed.
7.8 Manually operated valve should be operated by using the handle. Use of lowers or other tools is not allowed.
7.9 Valve in service should be examined at prescribed intervals to see whether the wear of sealing surface or stem occurs and the gasket or packing fails. Repair or replacement shall be carried out timely if necessary.
7.10 “Electric valve actuator instruction manual” and “Pneumatic valve actuator instruction manual” should be referred with regard to the storage, maintenance, installation and service for motor-operated valve and pneumatic-operated valve respectively.
