VF3330K-3GD1-02 SMC电磁阀

DSG-03电磁换向阀的特点及应用2011年11月15日13：53时，7#高炉炉顶￠650液压放散阀自动打开，造成高炉减风，后续在更换电磁换向阀后再次造成放散阀打开，致使高炉二次减风。

后经原因分析，认为是电磁换向阀内部定位器失效，导致电磁阀误动作。

该种电磁阀为双电磁铁二位四通电磁换向阀，现场使用的型号为：DSG-03-02-D2-D24-N-50。

各字母代表的含义如下：一、外形图二、内部结构该阀主要由阀体1，一个或两个电磁铁，控制阀芯3和一个或两个复位弹簧4组成。

在未通电状态下，控制阀芯2由复位弹簧4保持在中位，或初始位置（脉冲阀芯除外）。

由湿式电磁铁2完成控制阀芯3的操作。

为确保正确的功能，务必在电磁铁衔铁压力腔中充满油液。

电磁铁2的力经推杆5作用在控制阀芯3上，将其由静止位置推到所需的切换位置。

使P至A和B至T，或有使P至B和A至T之间处于连通状态。

当电磁铁2断电时，控制阀芯3被复位弹簧4推回初始位置。

手动应急按钮6，用于在电磁铁不同电的情况下，驱动控制阀芯3的运动。

这是一种双电磁铁二位方向阀，带定位机构。

阀在两个位置之间切换。

在多数情况下，无需持续向电磁铁供电，阀可保持在任一切换位置。

Preparation before pipingBefore piping is connected, it should be thoroughly blown outwith air (flushing) or washed to remove chips, cutting oil andother debris from inside the pipe.2. Wrapping of pipe tapeWhen screwing piping orfittings into ports, ensure thatchips from the pipe threads orsealing material do not enterthe piping. Also, if pipe tape isused, leave 1 thread ridgesexposed at the end of thethreads.3. Connection of fittingsWhen screwing fittings into valves, tighten as follows.Tightening Torque for PipingConnection thread size (R, NPT)Proper tightening torque (N·m)1/8 3～53/8 15～201/2 20～253/4 28～301 36～381 1/440～421 1/248～502 48～50Follow the procedure of the manufacturer when fittings other thanSMC is used.1) If the fitting is tightened with excessive torque, a large amountof sealant will seep out. Remove the excess sealant.2) Insufficient tightening may cause seal failure or loosen thethreads.3) For reuse(1) Normally, fittings with a sealant can be reused up to 2 to 3times.(2) To prevent air leakage through the sealant, remove anyloose sealant stuck to the fitting by blowing air over thethreaded portion.(3) If the sealant no longer provides effective sealing, windsealing tape over the sealant before reusing. Do not use anyform of sealant other than the tape type of sealant.(4) Once the fitting has been tightened, backing it out to itsoriginal position often causes the sealant to becomedefective. Air leakage will occur.4. Uni thread fittings1) First, tighten the threaded portion by hand, then use a suitablewrench to tighten the hexagonal portion of the body further atwrench tightening angle shown below. For the reference valuefor the tightening torque, refer to the table below.Connection Female Thread: Rc, NPT, NPTFUni thread sizeWrench tightening angleafter tightened by hand(deg)Tightening torque(N·m)1/8 30 to 60 3 to 53/8 15 to 45 14 to 161/2 15 to 30 20 to 22Connection Female Thread: GUni thread sizeWrench tightening angleafter tightened by hand(deg)Tightening torque(N·m)1/8 30 to 45 3 to 43/8 15 to 30 8 to 91/2 15 to 3014 to 152) The gasket can be reused up to 6 to 10 times. It can bereplaced easily when it has sustained damage. A broken gasketcan be removed by holding it and then turning it in the samedirection as loosening the thread. If the gasket is difficult toremove, cut it with nippers, etc. In such a case, use caution notto scratch the seat face because the seat face of the fitting’s45° gasket is the sealing face.5. Piping to productsWhen piping to a product, refer to the operation manual toavoid mistakes regarding the supply port, etc.LubricationThis is a valve which requires lubrication. Besure to lubricate it for operation.It may cause problems such as damage andmalfunction of the valve if it is not lubricated.A valve of vacuum specification needs overhaulfor cleaning and addition of grease because itcannot be lubricated without it. (Refer to page 8.)1) If a lubricant is used in the system, use class 1 turbine oil (noadditive), ISO VG32.2) Please contact SMC regarding class 2 turbine oil (withadditives), ISO VG32.Lubrication amountIf too much oil is supplied, the oil will be accumulated in theproduct, causing malfunction or response delay.Air Supply1. Use clean air.Do not use compressed air that contains chemicals, syntheticoils including organic solvents, salt or corrosive gases, etc., asit can cause damage or malfunction.1. Install an air filter.Install an air filter upstream near the valve. Select an air filterwith a filtration size of 5 ㎛or smaller.2. Take measures to ensure air quality, such as byinstalling an aftercooler, air dryer, or waterseparator.Compressed air that contains a large amount of drainage cancause malfunction of pneumatic equipment such as valves.Therefore, take appropriate measures to ensure air quality,such as by providing an aftercooler, air dryer, or waterseparator.Be sure to read before handling.CautionCautionWarningWarningAir Supply3. If excessive carbon powder is seen, install a mist separator on the upstream side of the valve.If excessive carbon dust is generated by the compressor, it may adhere to the inside of a valve and cause it to malfunction.For compressed air quality, refer to SMC’s Best Pneumatics catalog.Operating Environment1. Do not use in an atmosphere having corrosivegases, chemicals, sea water, water, water steam, or where there is direct contact with any of these . 2. Do not use in an environment where flammable gas or explosive gas exists. Usage may cause a fire or explosion.The products do not have an explosion proof construction.3. Do not use in a place subject to heavy vibration and/or shock.4. The valve should not be exposed to prolonged sunlight. Use a protective cover.Note that the valve is not for outdoor use. 5. Remove any sources of excessive heat.6. If it is used in an environment where there is possible contact with a waterdrop, oil, weld spatter, etc., exercise preventive measures.(1) Temperature of ambient environmentUse the valve within the range of the ambient temperature specification of each valve. In addition, pay attention when using the valve in environments where the temperature changes drastically.(2) Humidity of ambient environmentIf the humidity rises, take measures to prevent the adhesion of water droplets on the valve.Maintenance1. Perform maintenance inspection according to the procedures indicated in the operation manual.If handled improperly, malfunction and damage of machinery or equipment may occur.2. Removal of equipment, and supply/exhaust of compressed airWhen components are removed, first confirm that measures are in place to prevent workpieces from dropping, run-away equipment, etc. Then, cut off the supply pressure and electric power, and exhaust all compressed air from the system using the residual pressure release function.When the equipment is operated after remounting or replacement, first confirm that measures are in place to prevent lurching of actuators, etc. Then, confirm that the equipment is operating normally.3. Low frequency operationValves should be operated at least once every 30 days to prevent malfunction. (Use caution regarding the air supply.)4. If the volume of air leakage increases or the valve does not operate normally, do not use the valve.Perform periodic maintenance on the valve to confirm the operating condition and check for any air leakage.1. Drain flushing Remove drainage from the air filters regularly.CautionCautionCautionVPA31∗5 SeriesPrecautions for 3 Port Air Operated Valve ③Be sure to read before handling.Other Precautions1. Pressure balance among each portThis valve is pressure-unbalanced type. Operate it within this pressure range: IN ≧ OUT ≧ EXH. If not operated in the range, the valve will malfunction.2. Use as 2 port valve1) Plug EXH port in case of pressure-in and plug IN port in case of vacuum use.2) This valve has slight air leakage and can not be used for such purposes as holding air pressure (including vacuum) in the pressure container.3.
