第六章 气动执行元件
2、磁性耦合式无杆气缸
在活塞上安装了一组高磁性的永久磁环4，磁力 线通过缸筒与套在外面的另一组磁环2作用。由于 两组磁环极性相反具有很强的吸力。当活塞在一 侧输入气压作用下移动时，则在磁耦合力作用下 带动套筒与负载一起移动。
它的特点：小型、重量轻、无外部空气泄 漏、维修保养方便。当速度快、负载大时 ，内外磁环易脱开，即负载大小受速度影 响，且磁耦合的无杆气缸中间不可能增加 支撑点，最大行程受到限制。
如符合国际标准ISO6430、ISO6431、 ISO6432，符合我国标准GB8103-87（即 ISO6431）的都为标准化气缸。
对于ISO6431标准而言，标准主要内容 是对气缸的缸径系列、活塞杆伸出部分的 螺纹尺寸作了规定，对同一缸径的气缸的 外形尺寸(其长度、宽度、高度)作了限制， 对气缸的连接尺寸作了统一的规定。这一 规定仅针对外部连接尺寸的统一，而连接 件与气缸的连接尺寸未作规定。因此，对 于两家都符合ISO6431标准的气缸不能直 接互换，而必须连同连接件一起更换。这 一点在气缸选用时要特别注意
6．1．8 气液转换器
气液转换器是将气压直接转换为油压（增 压比为1:1）的一种气液转换元件。由于空 气有压缩性，而油液一般可不考虑压缩性 ，通过气液转换器可以获得液压驱动良好 的定位、稳定速度和调速特性，可用于精 密切削、精密稳定的进给运动。
当压缩空气由上部输 入管输入后，经管道 末端的缓冲装置使压 缩空气作用在液压油 面上，因而液压油即 以压缩空气相同的压 力，由转化器主体下 部的排油孔输出到液 压缸，使其动作。
6．1．3 冲击气缸
冲击气缸把压缩空气的能量转化为活塞高 速运动能量的一种气缸。活塞最大速度可 以达到10m/s以上，利用此动能做功，与 同尺寸的普通气缸相比，其冲击能要大上 百倍。

For more details about valves, positioners and accessories, refer to the separate installation, operating and maintenance instructions of the par-ticular unit.1.2Structure and operationThe BJ and B1J series actuators are pneumatic cylinder actuators designed for control and shut-off service.The linkage has PTFE, PE-HD and Glacier DU bearings. The robust cast-iron housing efficiently protects the mechanism from ambient dust and moisture.The spring provides the required safety function; the valve either opens or closes if the air supply is interrupted.The mounting face dimensions of the BJ actuator comply with the manufacturer ’s internal standard and those of the B1J with the ISO 5211 standard.In the BJ type, the spring is located on the piston rod side. The secondary shaft of the actuator, operated by the spring, rotates clockwise as seen from the pointer cover side. The piston then moves towards the end of the cylinder. The BJ type is normally applied for the spring-to-close operation, as it normally closes in the clockwise direction. The two keyways in the secondary shaft are positioned at an angle of 90° to each other, making it possible to change the position of the actuator in relation to the valve,see Fig. 1.In the BJA type, the spring is located in the cylinder end side. The secondary shaft, operated by the spring, rotates counter-clock-wise as seen from the pointer cover side. The piston moves away from the cylinder end. The BJA type is used for the spring-to-open function, see Fig. 1.The size of the spring actuator is selected according to the torque given by the spring. It is, however, important to check that there is sufficient supply pressure to give the required torque in the opposite direction.Screws are located in the upper end of the cylinder and in the lower end of the housing to regulate the length of the piston stroke and also the rotation angle of the actuator shaft.1.3Actuator markingsThe actuator is provided with an identification plate, see Fig. 2.Identification plate markings are:1.Type 2.

The torque changes according to supply pressure.1.5Recycling and disposal of a rejected actuatorMost actuator parts can be recycled if sorted according to material. Most parts have material marking. A material list is supplied with the actuator. In addition, separate recycling and disposal instructions are available from the manufacturer. An actuator can also be returned to the manufacturer for recycling and disposal against a fee.1.6Safety precautionsCAUTION:Don’t exceed the permitted values!Exceeding the permitted pressure value marked on the actuator may cause damage and lead to uncontrolled pressure release in the worst case. Damage to the equipment and personal injury may result.CAUTION:Don’t dismantle a pressurized actuator!Dismantling a pressurized actuator leads to uncontrolled pressure release. Shut off the supply pressure and release pressure from the cylinder before dismantling the actuator.Otherwise, personal injury and damage to equipment may result.CAUTION:Follow the instructions given on the actuator warning plates!CAUTION:Before opening the cylinder fastening screws,release spring tension directed on actuator warning plate and in these instructions!CAUTION:Don’t operate the actuator manually by turning from the lever arm!CAUTION:Don’t dismantle the spring package!The spring package within the cylinder is preloaded. The lock-welded fastening screw of the piston must never be opened or the spring package dismantled. The piston, piston rod, spring and spring plate of the BJ actuator are always delivered as a pre-assembled package.CAUTION:Don’t use the lever in the torsion arm for manual operation when the actuator is pressurized!Shut off the supply pressure and release pressure from the cylinder before using the hand lever. Note also the dynamic torque caused by the pipe flow.Otherwise, personal injury and damage to equipment may result.CAUTION:Take the weight of the actuator or valve combination into account when handling it!Do not lift the valve combination from the actuator,positioner or limit switch or their piping.Lift the actuator as directed in section 2,lifting ropes for a valve combination should be fastened around it.Weights are listed in the table on page 18.Dropping may result in personal injury or damage to equipment.M β / M Nβ °BJAFig. 3.Output torque a a function of turning angleM β / M Nβ °BJ42TRANSPORTATION, RECEPTION AND STORAGEMake sure that the actuator and associated equipment have not been damaged during transportation. Store the actuator carefully before installation, preferably indoors in a dry place. Do not take it to the installation site or remove the protective caps of ports for piping until just before installation.Lift the actuator as shown in Fig. 4: in a horizontal position from the stop screws, in a vertical position from an eye bolt screwed in the place of a stop screw. Do not use the lug for lifting dual-cylinder actuators. Refer to page 18 for weights.3MOUNTING AND DEMOUNTING 3.1Actuator gas supplyDry compressed air or natural gas can be used in actuators in open-close operation, no oil spraying is needed. Clean, dry and oil-free instrument air must be used for cylinder actuators with a positioner. The air supply connections are presented in the dimensional drawings on page 18. The maximum supply pressure is 8.5 bar.3.2Mounting the actutor on the valveCAUTION:Take the weight of the actuator or valve combination into account when handling it!CAUTION:Beware of the cutting movement of the valve!Install the actuator so that the shaft of the valve or any other device to be actuated goes into the shaft bore of the actuator.If the bore is larger than the shaft diameter, use a collar in between. The actuator shaft bore has two keyways at an angle of 90°. These allow the installation position of the actuator to be changed in relation to the valve. Metso Automation valves have a bevel at the end of their shafts to facilitate installation.The installation position can be selected freely, but Metso Automation recommends installation with the cylinder upright.The actuator is thus best protected against damage due to supply air impurities or water.When the installation position of the actuator is altered, the arrow indicating the operating direction must be turned to correspond with the actual operation of the valve.When necessary, lubricate the actuator bore and collar with Cortec VCI 369 or an equivalent anti-corrosive agent to prevent it from jamming due to rust.The actuator must not be allowed to come in contact with the pipework, because the vibrations may damage it or cause unsat-isfactory operation.In some cases, e.g. when using large actuators or with extensive pipework vibrations, the actuator should be supported. Consult Metso Automation for instructions.If the actuator is used with devices other than Metso Automation valves, any additional parts attached to the actuator must beproperly protected.Fig. 4.Lifting the actuatorFig. 5.Ways to install the actuator53.3Operating directions A sticker on the actuator cylinder indicates the spring action direction.NOTE:Separate instructions are available for adjusting the close limit of metal-seated butterly valves. Refer to the installation,operating and maintenance instructions of the valve.3.3.1BJ actuator -spring-to-close directionInstall the actuator on the valve with the piston in the upper end of the cylinder and the valve in the closed position, see Fig. 6.The cylinder must be depressurized and the air ports open.Adjust the closed-position setting using the stop screw (26) at the end of the cylinder. Seal the screw thread with a non-hard-ening sealant, such as Locktite 225 or the equivalent. The open-position setting is adjusted with the stop screw (27) at the bottom of the housing while the actuator is pressurized and the piston is in the lower position.3.3.2BJA actuator -spring-to-open directionInstall the actuator on the valve with the piston in the lower end of the cylinder and the valve in the open position, see fig 7. The cylinder must be unpressurized and the air ports open. Adjust the open-position setting using the stop screw (27) at the end of the cylinder. The close-position setting is adjusted with the stop screw (26) at the end of the cylinder while the actuator is pressurized and the piston is in the upper position.3.4Demounting the actuator from the valveCAUTION:Take the weight of the actuator or valve combination into account when handling it!CAUTION:Beware of the cutting movement of the valve!The actuator must be depressurized and the supply air pipes disconnected. Unscrew the actuator-side screws of the bracket and pull the actuator off the valve shaft. This is best done using a specific extractor, see fig 8 and section 6 ’Tools ’.Note the mutual positioning of the valve and the actuator to ensure correct functioning after reassembly.4MAINTENANCE 4.1GeneralCAUTION:Note the precautions in section 1.6 before beginning work!Under normal conditions, the actuators do not need regular maintenance. Maintenance procedures that the end user can do himself when necessary are described below.Unless stated otherwise, the part numbers given refer to the exploded view and parts list in section 8.In especially harsh corrosive conditions the linkage system inside the housing must be lubricated every six months. Use Cortec VCI 369 anti-corrosive agent or the equivalent. The housing may also be half filled with semi-fluid water-resistant grease (e.g.Mobilux EP2) while the piston rod is in the lower position.If you remove the stop screw, adjust the limits after lubrication or grease filling !2 keyways Closed-position stop screwOpen position stop screw80°90°Fig. 6.BJ actuator2 keyways Closed-position stop screwOpen position stop screw80°90°Fig. 7.BJA actuatorFig. 8.Removing the actuator with an extractor64.2Maintenance of the BJ actuatorCAUTION:Don ’t dismantle a pressurized actuator!CAUTION:To release spring tension, the stop screw at the end of the cylinder must be removed before the cylinder fastening screws are opened!CAUTION:Don ’t dismantle the spring package!The spring package within the cylinder is preloaded.

Burkert 2051QT气动旋转执行器说明书
Pneumatic rotary actuatorDouble acting and spring return The 2051QT pneumatic rotary actuators are ofthe rack and pinion type where the linear kineticenergy is directly transformed into a “quarter turn” operation with a constant output torque over the full stroke.Both double acting and spring return actuators have twin pistons horizontally opposed and incorporate piston guides to ensure correct contact between the rack and pinion at all pressures.High quality materials are employed throughout the construction and the compact design is readily fitted to any type of ball valve, butterfly valve or other equipment requiring efficient pneumatic actuators.The actuator is suitable for mounting a full range of accessories, such as limit switches, solenoid valves, positioners and manual override gearbox.Extruded aluminium alloy, gold anodizedPressure die cast aluminium alloy, black epoxy coated Carbon steel, zinc platedType 6519NAMUR Solenoid valve Type 8792/93 Positioner SideControlType MV2650Ball valve Type 1062QTPosition feedbackType VV2670Butterfly valveFunctional principleDouble acting actuator (DA)Counter clockwise output operation is achieved by inserting pressure into Port ‘A’, to force piston apart thus rotating the actuator pinion counter clockwise. During the operation, air from the outer chambers is exhausted through Port ‘B’. Clockwise output operation is achieved by reverse of the above and inserting pressure into Port ‘B’.Single acting actuator (SR)Pressure applied to Port ‘A’ will cause the inner chambers to be pressurized, forcing the pistons outward to compress the springs. The pinion is rotated counter clockwise. Upon release of pressure through Port ‘A’ the springs will exert pressure to close the pistons and rotate the pinion clockwise rapidly. This action will often be used to close a 90oturn valve in shutdown mode.Pistons assembly variationsArrangement of springs for single acting actuatorActuator direction of rotation can be changed by switching both the pistons in accordance to the below diagramSprings can be added or removed according to torque requirement. It is recommended to install springs in accordance to the below diagramAir ConsumptionFree Air per stroke (Liters)Opening / Closing timeat 5.6 bar airWeight (kg)Torque Output (Nm) | Ordering Chart (other versions on request) Double acting actuator (DA)Torque Output (Nm) | Ordering Chart (other versions on request) Single acting actuator (SR)Dimensions [mm]AP01 to AP10 DA/ SR*** To be specified during order.
