DJFK6型角阀控制器说明书

电动调节阀使用说明格，将面临新的挑战，尤其是在国际矿业巨头继续扩大垄断，谈判双方实力严重失衡的大环境下。

实际上，今年的铁矿石价格谈判时间未到，却早已引起国内外的关注了。

目前，我国铁矿石自给率约为45％至50％，另外一半需要进口，进口分为现货进口和长期协议进口两部分。

作为世界上最大的铁矿石进口国，我国在世界上的地位绝对是举足轻重的。

然而，近几年来，我国钢企参加了几次国际铁矿石价格谈判，但效果都不明显。

主要原因是我国的钢铁产业集中度低、钢企之间的力量分散，造成一、产品[电子式三通电动调节阀]的详细资料：产品型号：ZDSF（H）型产品名称：电子式三通电动调节阀产品特点：ZDSF（H）型直行程分流、合流电动调节阀，由三通分流，合流阀门配用德国进口PS系列直行程电动执行机构组成。

All applicable legal or institutional installation regulations must be complied during installation.The valve does not contain any parts that can be replaced or repaired by the user.The valve may not be disposed of as household refuse. All locally valid regulations and requirements must be observed.When determining the flow rate characteristic of controlled devices, the recognised directives must be observed.Product featuresThe 6-way characterised control valve is adjusted by a rotary actuator. The actuator is connected by a modulating control system or a bus signal and moves the ball of the ball valve to the position dictated by the control signal.If the valve is adjusted in the clockwise direction (till the end stop), e.g. the cooling sequence is completely enabled; if the valve is adjusted in the counter-clockwise direction (90°), e.g. the heating sequence is completely enabled.In cases of combined heating/cooling control elements, the fluid remains in the control element when in the closed position (no heating or cooling). The pressure of the enclosed fluid can rise or fall due to changes in fluid temperature caused by the ambient temperature. The 6-way characterised control valves have an integrated pressure relief function for the purpose of compensating for such pressure changes.The pressure relief function is active in the closed position (45°) of the valve; reliable separation of Sequences 1 and 2 continues. For additional information, consult the notes for project planning for the 6-way characterised control valve.AccessoriesMechanical accessoriesDescriptionType Elbow 90° male/female DN 15 Rp 1/2, R 1/2, Set of 2 pcs.P2P15PE-1GE Fixing bracket for 6-way valve DN 15/20ZR-004Pipe connector for ball valve DN 15ZR2315Installation notesThe ball valve can be installed upright to horizontal. The ball valve may not be installed in ahanging position, i.e. with the spindle pointing downwards.The water quality requirements specified in VDI 2035 must be adhered to.Belimo valves are regulating devices. For the valves to function correctly in the long term, they must be kept free from particle debris (e.g. welding beads during installation work). The installation of a suitable strainer is recommended.R3015-..-..-B1ServicingFlow directionValve characteristic curve Using an additional flow limiterBall valves and rotary actuators are maintenance-free.Before any service work on the control element is carried out, it is essential to isolate the rotary actuator from the power supply (by unplugging the electrical cable if necessary). Any pumps in the part of the piping system concerned must also be switched off and the appropriate slide valves closed (allow all components to cool down first if necessary and always reduce the system pressure to ambient pressure level).The system must not be returned to service until the ball valve and the rotary actuator have been correctly reassembled in accordance with the instructions and the pipeline has been refilled by professionally trained personnel.The flow direction must be observed. The position of the ball can be identified from the L-marking on the spindle.The lower diagram shows the valve characteristic curve in relation to the ball position.When using additional flow limiting valves (e.g. PIQCV C2..QP(T)-.. with manual flow rate setting) or an additional pressure-independent control valve (e.g. motorised PIQCV) at the system level, it is not necessary to use the flow characterised disc in the 6-way valve in the system to reduce the kvs value.R3015-..-..-B1 DimensionsDimensional drawingsThe actuator dimensions can be found on the respective actuator data sheet.Further documentation• The complete product range for water applications• Data sheets for actuators• Installation instructions for actuators and/or ball valves• Notes for project planning for 6-way characterised control valves。

4/3 and 4/2 Directional Spool Valves, ISO Size 03Q max = 80 l/min, p max = 350 bar Direct acting, solenoid operatedSeries WEDO…1/7Reference: 400-P-181110-EN-01Issue: 08.2021S For controlling the starting, stopping,and direction of a flowS Manifold-mounting design, interface to ISO 4401-03-02S Operated by DC or AC solenoidsS Very reliable functions and extremely stable S With manual overrideS Solenoid coils can be changed quickly and easily wi­thout leakage from hydraulics system.1DescriptionThe WEDO-…-6… series of directional spool valves are so­lenoid operated, direct acting, manifold-mounting valves with a size 03 interface to ISO 4401-03-02. The main components of the valves are a steel body, either one or two solenoids, the control spool, and either one or two return springs. In the non-operated state, the return springs hold the control spool in the middle position or initial position. The control spool is operated by the DC or AC solenoids, whichare of the oil-immersed type. The integral manual override can be used to move the spool without energising the coil,for example during a power failure. These 4/3 and 4/2 direc­tional valves are used in plant and machines to control the direction of a flow, and to stop the flow. The slip-on coils can be replaced without opening the hydraulic envelope and can be positioned at any angle through 4x90°. The version WEDO-42-C-6... is fitted with a mechanical detent setting.2Technical dataGeneral characteristics Description, value, unitDesignation 4/3 and 4/2 directional spool valvesDesignflange design, direct acting, electrically operated Mounting method 4 mounting holes for M5x30 mounting bolts(valve mounting bolts supplied with the valve)Tightening torque 5.2 Nm ± 10 %Size size 03 interface to ISO 4401-03-02Weight- valve with one solenoid - valve with two solenoids1.60 kg2.10 kgMounting attitudehorizontal recommended(vertical mounting makes air bleeding difficult)Ambient temperature range-20 °C … +80 °C400-P-181110-EN-01/08.2021Series WEDO…2/7Hydraulic characteristics Description, value, unit Maximum operating pressure - ports A, B, P - port T350 bar 210 bar Maximum flow rate DC AC80 l/min 60 l/minFlow direction see table “Symbols / Spool types”Hydraulic fluidHL and HLP mineral oil to DIN 51 524;HEES biodegradable fluids;for other fluids, please consult BUCHER Hydraulic fluid temperature range -20 °C … +80 °CViscosity range10…500 mm 2/s (cSt), recommended 15...250 mm 2/s (cSt)Minimum fluid cleanlinessCleanliness class to ISO 4406 : 1999class 20/18/15Electrical characteristics Description, value, unitStandard - Supply voltage 12 V DC, 24 V DC / 110 V AC, 220 V AC (50 … 60 Hz)Supply voltage tolerance ± 10 %Ambient temperature range -20 °C … +50 °C Nominal power consumption DC AC 30/31 W energising 225 VA (RMS) / holding39 VA (RMS)Switching time bei 40 l/min, 175 barDC AC45 ms (energising)28 ms (deenergising)15 ms (energising)23 ms(deenergising)Depending on pressure, flow rate, pressure drop and viscosity as well as dwell time under pressure, the switching times may vary from the the stated values.Relative duty cycle100 %Protection class to ISO 20 653 / EN 60 529IP65(with appropriate mating connector and proper fitting and sealing)Electrical connectionDIN EN 175301-803, 3-pin 2 P+E (standard)for other connectors, see “Ordering code”400-P-181110-EN-01/08.2021 Series WEDO…3/73Symbols / Spool types400-P-181110-EN-01/08.2021Series WEDO…4/74Performance graphsmeasured with oil viscosity 33 mm 2/s (cSt), coil at steady-state temperature and 10 % undervoltage Δp = f (Q) Pressure drop - Flow rate characteristicA, B, C, D, F, G, H and J spool0Q [l/min]60504030201024681012p [bar]P0434.ai43215678Spool type Flow directionP % A P % B P % T A % T B % T A % B B % A A / B / C 66–55––AN / BN / CN55–22––D 55–22––F 6* 46** 4–337 + +7 + +G 66–3* 13+ 1––H 44 4 +22––J66844––*in mid–position, B closed **in mid–position, A closed +in mid–position, A + B closed ++in mid–position, P closed400-P-181110-EN-01/08.2021Series WEDO…5/7p = f (Q) Performance limits with AC-solenoid coil operating at 50 Hz0Q [l/min]60504030201050100150200250350p [bar]P0435.ai4321300Spool typeFlow direc­tionA 2B 2C 2D 1F 1G 4H 1J3p = f (Q) Performance limits - wIth DC-solenoid coil0Q [l/min]80705040301050100150200300350p [bar]P0436.ai542120603235250Spool typeFlow direc­tionA 3B 3C 3D 1F 2G 5H 2J4IMPORTANT!The indicated performance limits apply when symmetrical flows pass through the valve.For non-symmetrical flows, the max. flows are substantially reduced, in worst cases to 33%.400-P-181110-EN-01/08.2021Series WEDO…6/75Dimensions & sectional view4/3 spool valve (spring centred)4/2 spool valve (pulse signal, detented)1)4/2 spool valve (1-solenoid model, A or B side)± 5%M A Seal kit NBR no.

It eliminates the need for a change-over valve and enables the use of a single coil for heating and cooling.B320-116-186 Operation A loop pressure relief is designed into port number two (2). This allows the increased pressureto dissipate to the supply loop on port number one (1). This is intended to release any pressurebuild up in the loop (coil) when the valve is in the closed position and is isolated from the systemexpansion vessel. The change in pressure occurs due to a change in the media temperature inthe coil while isolated from the pressure vessel. The pressure relief does not affect the efficiencyof the system because cross-flow cannot occur between the heating and cooling loops. Thesystem loops (heating/cooling) should share a common expansion vessel to keep the systempressure and volume balanced.Flow/Mounting detailsAccessoriesMechanical accessories Description TypeFixing bracket for 6-way valve DN 15/20ZR-004 DimensionsType DN WeightB320-116-18620 4.63 lb [2.1 kg]A B C D E F G H1H27.5" [191] 3.9" [100]9.0" [229]7.6" [194] 2.0" [51]2.0" [51]2.4" [60]1.2" [30]0.6" [15]LRX24-MFTModulating, Non-Spring Return, 24 V, Multi-Function Technology®Technical dataElectrical dataNominal voltageAC/DC 24 V Nominal voltage frequency 50/60 HzNominal voltage rangeAC 19.2...28.8 V / DC 21.6...28.8 V Power consumption in operation 2.5 W Power consumption in rest position 1.2 W Transformer sizing 5 VAElectrical Connection18 GA plenum cable with 1/2" conduitconnector, degree of protection NEMA 2 / IP54, 1 m 3 m and 5 mOverload Protection electronic thoughout 0...90° rotation Electrical Protectionactuators are double insulated Functional dataOperating range Y 2...10 VOperating range Y note 4...20 mA w/ ZG-R01 (500 Ω, 1/4 W resistor)Input Impedance100 kΩ for DC 2...10 V (0.1 mA), 500 Ω for 4...20 mA, 1500 Ω for PWM and On/Off Operating range Y variable Start point 0.5...30 V End point 2.5...32 VOperating modes optional variable (VDC, on/off, floating point)Position feedback U 2...10 V Position feedback U note Max. 0.5 mA Position feedback U variable VDC variableDirection of motion motor selectable with switch 0/1Manual override external push button Angle of rotation 90°Angle of rotation note adjustable with mechanical stop Running Time (Motor)150 s / 90°Running time motor variable 35...150 s Noise level, motor 35 dB(A)Position indicationMechanically, pluggable Safety dataPower source ULClass 2 Supply Degree of protection IEC/EN IP54Degree of protection NEMA/UL NEMA 2Enclosure UL Enclosure Type 2Agency Listing cULus acc. to UL60730-1A/-2-14, CAN/CSA E60730-1:02, CE acc. to 2014/30/EU Quality Standard ISO 9001UL 2043 CompliantSuitable for use in air plenums per Section 300.22(C) of the NEC and Section 602 of the IMCAmbient humidityMax. 95% RH, non-condensingLRX24-MFTFootnotesSafety dataAmbient temperature -22...122°F [-30...50°C]Storage temperature -40...176°F [-40...80°C]Servicingmaintenance-free Weight Weight1.5 lb [0.70 kg]MaterialsHousing material Galvanized steel and plastic housing†Rated Impulse Voltage 800V, Type action 1.B, Control Pollution Degree 3.AccessoriesGatewaysDescriptionType Gateway MP to BACnet MS/TP UK24BAC Gateway MP to Modbus RTU UK24MOD Gateway MP to LonWorksUK24LON Electrical accessoriesDescriptionType Battery backup system, for non-spring return models NSV24 US Battery, 12 V, 1.2 Ah (two required)NSV-BAT Auxiliary switch 1 x SPDT add-on S1A Auxiliary switch 2 x SPDT add-onS2AFeedback potentiometer 140 Ω add-on, grey P140A GR Feedback potentiometer 1 kΩ add-on, grey P1000A GR Feedback potentiometer 10 kΩ add-on, grey P10000A GR Feedback potentiometer 2.8 kΩ add-on, grey P2800A GR Feedback potentiometer 500 Ω add-on, grey P500A GR Feedback potentiometer 5 kΩ add-on, greyP5000A GR ToolsDescriptionTypeConnection cable 10 ft [3 m], A: RJ11 6/4 ZTH EU, B: 3-pin Weidmüller and supply connectionZK4-GEN Service Tool, with ZIP-USB function, for programmable and communicative Belimo actuators, VAV controller and HVAC performance devicesZTH USElectrical installationINSTALLATION NOTESProvide overload protection and disconnect as required.Actuators may be connected in parallel.

m时应尽量设置平台,以利于操作手轮和便于进行维修;⑷调节阀安装前应对管路进行清洗,排除污物和焊渣;安装后,为保证不使杂质残留在阀体内,还应再次对阀门进行清洗,即通入介质时应使所有阀门开启,以免杂质卡住;在使用手轮机构后,应恢复到原来的空档位置;⑸为了使调节阀在发生故障或维修的情况下使生产过程能继续进行,调节阀应加旁通管路;同时还应特别注意,调节阀的安装位置是否符合工艺过程的要求;⑹电动调节阀的电气部分安装应根据有关电气设备施工要求进行;如是隔爆型产品应按爆炸危险场所电气设备安装规范要求进行安装;如现场导线采用SBH型或其它六芯或八芯、外径为 mm左右的胶皮安装电缆线;在使用维修中,在易爆场所严禁通电开盖维修和对隔爆面进行撬打;同时在拆装中不要磕伤或划伤隔爆面,检修后要还原成原来的隔爆要求状态;⑺执行机构的减速器拆修后应注意加油润滑,低速电机一般不要拆洗加油;装配后还应检查阀位与阀位开度指示是否相符;调节阀系列选型系统应用调节阀选型软件之所以上升为选型系统,有它的创新点所在：1 选型系统借助互联网,将企业在全国各地销售网点的订货信息自动传输至企业本部信息系统中,进行销售商务处理自动报价、合同评审、计划排产等,改变以往发邮件再人工重复录入的工作模式;2 远程自动判别订货产品是属于常规产品或特殊产品,调节阀产品选型系统可以使销售人员在公司外与客户签订合同前,利用软件系统,自动判别所选产品是否属于特殊品,为商务洽谈技术提供依据;3 可远程更新软件版本,随时可将产品的更新信息发布到各销售网点,保证销售选型人员得到的始终是最新的产品数据,从而保证了选型人员所选的产品信息与企业内部设计信息一致,减少了中间的出错环节;性能1.由于不需要进行系统调试,所以省去许多麻烦,节约了大量的时间,缩短竣工日期；2.由于不用使用阀门组和用于分层控制的阀门,所以为您节约了较多的管材,保温材料及安装费用和时间；3.使水系统时时刻刻都处于平衡状态,所以无论安装分期施工或设备分期使用都不会影响水系统的平衡;4.即使工程后期或投入运行后因改变某些用途而需要改变某些区域的水系统设计,也不会影响其他区域的水系统设计,更不会影响区域的水系统平衡;5.由于整个系统处于动态平衡状态,所以制冷机组及水泵将以最节能状态运行,节省了运行维护费用;6.由于系统的流量平衡是自动进行的,使安装维护更加便利,并杜绝了人为操作失误破坏平衡的可能;特点用途具有体积小,重量轻、连线简单、流量大、调节精度高等特点,广泛应用于电力、石油、化工、冶金、环保、轻工、教学和科研设备等行业的工业过程自动控制系统中;电动调节阀阀内组件：阀芯型式：上导单座套筒柱塞型阀芯流量特性：直线特性、等百分比特性或快开特性材料：1Cr18Ni9Ti 0Cr18Ni12Mo2Ti电动调节阀的用途及作用用于调节工业自动化过程控制领域中的介质流量、压力、温度、液位等工艺参数;电动调节阀适用范围空调、供暖、蒸气用电动调节阀通风、生活热水等民用系统及化工、石油冶金、电力轻工业等各行业生产过程中的自动控制;阀体结构选用要点⒈ 电动调节阀选用主要控制参数为：公称直径、设计公称压力、介质允许温度范围、流量系数等;⒉ 对于要求流量和开启高度成正比例关系的严格场合,应选用专用调节阀;球阀和蝶阀一般粗调时可以选用;⒊阀门的密封性能是考核阀门质量优劣的主要指标之一;阀门的密封性能主要包括两个方面,即内漏和外漏;内漏是指阀座与关闭件之间对介质达到的密封程度;外漏是指阀杆填料部位的泄露,中口垫片部位的泄露以及阀体因铸造缺陷造成的泄露;外漏是不允许发生的;⒋ 调节阀理想流量特性有快开、抛物线、线性、等百分比四种,需根据实际工作流量特性选择具有合适流量特性的调节阀;流量特性的选择原则见表1;表1 按配管情况选择阀门的特性注：S=调节阀全开时的压力损失/调节阀所在串联支路的总压力损失;为了避免通过阀门的水流速过高并尽量节省水泵功耗,宜使阀门工作状态的S≤.⒌ 调节阀公称直径的选取应根据所需阀门流通能力确定;调节阀公称直径不应过大或过小;过大,增加工程成本,并且阀门处于低百分比范围内,调节精度降低,使控制性能变差;过小,增加系统阻力,甚至会出现阀门100%开启时,系统仍无法达到设定的容量要求;6、调节阀的调节压差和关断压差对于调节阀,其允许的调节压差和关断压差是其选型的重要指标;实际压差如高于调节阀允许的调节压差,阀门会出现不能准确调节的问题,严重的会损伤阀门执行器;安装要点⒈ ；阀门的安装位置、高度、进出口方向必须符合符合口方向；设计要求,连接应牢固紧密;⒉ ；阀门可用各种形式的端部与管路连接;其中最主要的连接方式有螺纹、法兰及焊接连接;法兰连接时,若温度超过350℃时,由于螺栓、法兰和垫片蠕变松弛,应选择耐高温螺栓材料;⒊ ；阀门安装前必须进行外观检查,阀门的铭牌应符合现行国家标准GB12220通用阀门标志的规定;对于工作压力大于及在主干管上起到切断作用的阀门,应进行强度和严密性试验,合格后方准使用;其他阀门可不单独进行试验,待在系统试压中检验;⒋ ；强度试验时,试验压力为公称压力的倍,持续时间不少于5min,阀门的壳体、填料应无渗漏;⒌ ；严密性试验时,试验压力为公称压力的倍；试验压力在试验持续的时间内应保持不变,时间应符合表2的规定,以阀瓣密封面无渗漏为合格;⒍ ；公称通径：DN15~500表2 阀门压力持续时间执行标准产品标准GB/T13927-92通用阀门压力试验JB/T5296-91通用阀门流量系数和流阻系数的试验方法JB/T8528-1997普通型阀门电动装置技术条件GB12220-89通用阀门标志工程标准GB50243-2002通风与空调工程施工质量验收规范GB50242-2002建筑给水排水及采暖工程施工质量验收规范特点调节阀主要由阀体、套筒、阀瓣、阀杆等零件组成;套筒和阀瓣上都开有节流孔通过阀瓣在阀座内回转来改变过流面积,调节流量;配ZKJ型或其它型电动角行程执行器可实现遥控和自动控制;调节阀广泛应用于给水管路中作调节流量使用;也可在油品管路中使用;性能⒈由于不需要进行系统调试,所以省去许多麻烦,节约了大量的时间,缩短竣工日期；⒉由于不用使用阀门组和用于分层控制的阀门,所以为您节约了较多的管材,保温材料及安装费用和时间；⒊使水系统时时刻刻都处于平衡状态,所以无论安装分期施工或设备分期使用都不会影响水系统的平衡.⒋即使工程后期或投入运行后因改变某些用途而需要改变某些区域的水系统设计,不会影响其他区域的水系统设计,更不会影响其他区域的水系统平衡;⒌由于整个系统处于动态平衡状态,所以制冷机组及水泵将以最节能状态运行,节省了大量维护费用.⒍由于系统的流量平衡是自动进行的,使安装维护更加便利,并杜绝了人为操作失误破坏平衡的可能.优点除高可靠、全功能、超轻型的特点外,电动调节阀还有如下好处：⑴用电源既方便又节约,省去了建立气源站的一系列费用；⑵用“气动阀+电气阀门定位器+气源”的复杂方式,它不只是增加了费用,反而带来了可靠性的下降环节越多,可靠性差的因素增加；⑶从经济性上看,除省去气源站的费用外,还省去电气阀门定位器的费用：一台好的进口的电气阀门定位器,通常在5000～6000元以上,更好的在8000～10000的价位上,而这个价位基本上可购回上述高可靠的电子式执行机构；⑷环节减少了,相应减少了维修工作量;缺点电动调节阀也不是没有缺点：电机运行产生的内热会导致热保护,使调节阀停止工作；由于电机必须经过多级减速才能输出力矩,所以运行速度还不是很快,在有些要求快速启闭的场合还不适用,大力矩和高速,还是一个比较难以解决的矛盾；由于运动部件多,相对容易产生故障,尤其在调节频繁的工况,容易产生电机热保护、减速齿轮损坏、模块可控硅烧毁等故障,在这种工况下,最好还是选用气动调节阀比较适宜;。
