实施电磁阀控制系统是一个不可或缺的元素,因为它的体积小,开关速度快、简单的布线、低功耗、高性能价格比和其他重要的经济实用的特点,广泛应用于自动控制领域的每个环节,发挥了巨大的作用。电磁阀是一种流体控制阀门,尽管其众多优势,但选择的准确与否直接影响到阀门本身的使用效果和系统的稳定性,甚至严重后果的自动控制系统。和机械设备常用的气动电磁阀和液压电磁阀、流量电磁阀的选择和使用更复杂的比单一介质电磁阀、电磁阀执行机构的部分原因,尽管外表自动化仪表和其他手动阀是相似的,但是内部结构非常好,和一般手动阀有着本质的区别。commonmanualvalveswitchcompletelydependonthesizeoftheartificialhardtooperate,electromagneticvalvecompletelyonitsownthefunctionofthecontrolpurpose,;solenoidvalveisdistinguishedfromothervalvesbecauseofitsinternalstructureisdifferent,thedifferentworkingmediumcan'tgeneralavalve,onceconfirmedthatthemediatypeandtheselectedsolenoidvalveproductswillnotbeblendedwithdifferentmedia,otherwiseitwillleadtothefailureordamageofsolenoidvalve,solenoidvalve,asaprofessionalstrongindustrialproducts,intheselectionshouldbeaccordingtotheactualworkingconditionandtechnologicalparametersoftheautomaticcontrolsystem,andreferringtorelatedproductmanualtoselectthecorrespondingproduct,ordirectlycommunicatewithspecializedtechnicalpersonnel,choosetomeettherequirementsofthecontrolsystemproducts,choicethanactualsystemtoductileironpipesaretoohighandtoolowfortheparametersofsolenoidvalveisnotconducivetoplayaroleoftheductilepipeinthesystemcontrol,andcauseunnecessarylossandwaste;underneaththeelectromagneticductileironpipevalvesweresimpleclassification ne,tobecontrolledwithinthelineofmediumandusingdifferentoftheminingcanbedividedinto:liquidwithelectromagneticvalve,gaswithsolenoidvalve,solenoidvalve,steamgassolenoidvalve,oilsolenoidvalve,ductileironpipefirespecialelectromagneticvalve,solenoidvalve,solenoidvalve,solenoidvalveinhightemperatureandhighpressuresolenoidvalveanddifferentialpressuresolenoidvalves,cryogenicsolenoidvalve(cryogenicsolenoidvalve),vacuumelectromagneticvalve,etc.;second,accordingtotheelectromagneticvalveinternalstructurecanbedividedintodifferentpilottype,straightmovingtype,complex,something,sincekeeptype,pulsetype,doublesteady,two-waytype,etc.;3,accordingtotheuseofelectromagneticvalvematerialisqualitativedifferentcanbedividedinto:castironbody(grayiron,ductilecastiron),copperbody(ductilecastingcastingcopper,copper),caststeel,stainlesssteelbody(304,316),non-metallicmaterials(abs,ptfe).4,根据不同的球墨铸铁管中介的压力可以分为:真空式(0.1~0mpa)、低电压型(0~0.8mpa)、中压型(1.0~2.5mpa)、高压力类型(4.0~6.4mpa)和超高压类型(10~21mpa)。5日,根据不同可以分为:在室温下的介质温度(5~80℃),温度式高温(100~150℃)类型(150~220℃)的超高温(250~450℃)和低温类型(40~0℃)、低温电磁阀(196℃)。6日,根据不同的工作电压分为:交流电压:ac220v,380v,110v,24v;直流电压:dc24v,12v,6v,220v电压为ac220v;一般常见,dc24v,建议客户尽可能选择常见的电压,特殊的电压供应周期长。七、根据保护水平的电磁阀可以分为:防爆型、防水、防尘、类型、户外水下特殊等;
