阀门专业术语及英文注解

阀门行业术语强度性能阀门的强度性能是指阀门承受介质压力的能力。阀门是承受内压的机械产品，因而必须具有足够的强度和刚度，以保证长期使用而不发生破裂或产生变形。密封性能阀门的密封性能是指阀门各密封部位阻止介质泄漏的能力，它是阀门最重要的技术性能指标阀门的密封部位有三处：启闭件与阀座两密封面间的接触处；填料与阀杆和填料函的配和处；阀体与阀盖的连接处。其中前一处的泄漏叫做内漏，也就是通常所说的关不严，它将影响阀门截断介质的能力。对于截断阀类来说，内漏是不允许的。后两处的泄漏叫做外漏，即介质从阀内泄漏到阀外。外漏会造成物料损失，污染环境，严重时还会造成事故。对于易燃易爆、有毒或有放射的介质，外漏更是不能允许的，因而阀门必须具有可靠的密封性能。流动介质介质流过阀门后会产生压力损失（既阀门前后的压力差），也就是阀门对介质的流动有一定的阻力，介质为克服阀门的阻力就要消耗一定的能量。从节约能源上考虑，设计和制造阀门时，要尽可能降低阀门对流动介质的阻力。启闭力和启闭力矩启闭力和启闭力矩是指阀门开启或关闭所必须施加的作用力或力矩。关闭阀门时，需要使启闭件与发座两密封面间形成一定的密封比压，同时还要克服阀杆与填料之间、阀杆与螺母的螺纹之间、阀杆端部支承处及其他磨擦部位的摩擦力，因而必须施加一定的关闭力和关闭力矩，阀门在启闭过程中，所需要的启闭力和启闭力矩是变化的，其最大值是在关闭的最终瞬时或开启的最初瞬时。设计和制造阀门时应力求降低其关闭力和关闭力矩。启闭速度启闭速度是用阀门完成一次开启或关闭动作所需的时间来表示。一般对阀门的启闭速度无严格要求，但有些工况对启闭速度有特殊要求，如有的要求迅速开启或关闭，以防发生事故，有的要求缓慢关闭，以防产生水击等，这在选用阀门类型时应加以考虑。动作灵敏度和可靠性这是指阀门对于介质参数变化，做出相应反应的敏感程度。对于节流阀、减压阀、调节阀等用来调节介质参数的阀门以及安全阀、疏水阀等具有特定功能的阀门来说，其功能灵敏度与可靠性是十分重要的技术性能指标。使用寿命它表示阀门的耐用程度，是阀门的重要性能指标，并具有很大的经济意义。通常以能保证密封要求的启闭次数来表示，也可以用使用时间来表示。类型type按用途或主要结构特点对阀门的分类型号model按类型、传动方式、连接形式、结构特点、阀座密封面材料和公称压力等对阀门的编号连接尺寸connectiondimensions阀门和管道连接部位的尺寸主要外形尺寸generaldimensions阀门的开启和关闭高度、手轮直径以及连接尺寸等连接形式typeofconnection阀门与管道或机器设备的连接所采用的各种方式（如法兰连接\螺纹连接\焊接连接等密封试验sealtest检验启闭件和阀体密封副性能的试验上密封试验backsealtest检验阀杆与阀盖密封副密封性能的试验密封试验压力sealtestpressure阀门进行密封试验时规定的压力适用介质suitablemedium阀门能适用的介质适用温度suitabletemperature阀门适用的介质的温度范围密封面sealingface启闭件与阀座（阀体）紧密贴合，起密封作用的两个接触面启闭件disc用于截断或调节介质流通的一种零件的统称，如闸阀中的闸板、节流阀中的阀瓣等填料packing装入填料函（或填料箱）中，阻止介质从阀杆处泄漏的填充物填料垫packingseat支承填料，保持填料密封的零件填料压盖gland用以压紧填料达到密封的零件支架yoke在阀盖或阀体上，用于支承阀杆螺母和传动机构的零件连接槽尺寸dimensionofconnectingchannel启闭件与阀杆装配连接部位的结构尺寸流道面积flowarea指阀门进口端到阀座密封面间的最小截面积（但不是指“帘”面积），用来计算无任何阻力影响时的理论排量流道直径flowdiameter对应于流道面积的直径流量特性flowcharacteristics稳定流动状态下，当进口压力等参数不变时，减压阀的出口压力与流量的函数关系流量特性偏差flowcharacteristicsderivation稳定流动状态下，当进口压力等参数不变时，减压阀流量的变化所引起的出口压力变化值通用阀门generalvalve各工业企业中管道上普遍采用的阀门自动阀门Self-actingvalve依靠介质（液体、空气、蒸汽等）本身的能力而自行动作的阀门驱动阀门Actuatedvalve借助手动、电力、液压或气压来操纵的阀门撞击手轮hammerblowhandwheel利用撞击作用力以减轻阀门操作力的手轮结构蜗轮传动装置wormgearactuator用蜗轮机构启闭或调节阀门的装置气动装置pneumaticactuator用气压力启闭或调节阀门的驱动装置液动装置hydraulicactuator用液压力启闭或调节阀门的驱动装置热凝结水排量Hotcondensatecapacity在给定压差和温度下疏水阀一/j咐内能排出凝结水的；犀大重量漏汽量Steamloss单位时间内疏水阀漏出新鲜蒸气的量CQ螺纹球阀CQThreadBallValvesL形三通式L-patternthreewayT形三通式T-patternthreeway安全阀Safetyvalve暗杆闸阀Insidescrewnonrisingstemtypegatevalve百叶窗;闸板shutter百叶窗式挡板louverdamper摆阀式活塞泵swinggatepistonpump保温式Steamjackettype报警阀alarmvalve报警阀;信号阀;脉冲阀sentinelvalve背压调节阀backpressureregulatingvalve背压率Rateofbackpressure本体阀杆密封bodystemseal波纹管阀Bellowsvalves波纹管密封阀bellowsealedvalve波纹管密封式Bellowssealtype波纹管平衡式安全阀Bellowssealbalancesafetyvalve波纹管式减压阀Bellowsreducingvalve波纹管式减压阀Bellowswealreducingvalve薄膜thinfilm薄膜;隔膜diaphragm薄膜式减压阀Diaphragmreducingvalve薄型闸阀ThinGateValves不封闭式Unsealtype槽车球阀TankLorryBallValves颤振Flutter常闭式Normallyclosedtype常开式Normallyopentype超低温阀门Cryogenicvalve超高压阀门Superhighpressurevalve超过压力Overpressureofasafetyvalve衬胶隔膜阀rubberlineddiaphragm衬胶截止阀rubberlinedglobevalve垂直板式蝶阀Verticaldisctypebutterflyvalve磁耦合截止阀MagneticCo-operateGlobeValves带补充载荷的安全阀Supplementaryloadedsafetyvalve带辅助装置的安全阀Assistedsafetyvalve单阀碟双面平行密封闸阀parallelsinglediskgatevalve单口排气阀SingleOpeningExhaustValves单向阀Non-returnValve单闸板Singlegatedisc单闸板平板闸阀SingleDiscFlatGateValves弹簧薄膜式减压阀Springdiaphragmreducingvalve弹簧式安全阀Directspringloadedsafetyvalve弹簧座Springplate弹性闸板Flexiblegatedisc当量计算排量Equivalentcalculatedcapacity挡板damper导阀Pilotvalve导向套Valveguidediscguide低温阀门Sub-zerovalve低压阀门Lowpressurevalve底阀bottomvalve底阀Footvalve电磁动装置Eletromagneticactuator电磁阀magneticvalve电磁阀solenoidvalve电磁－液动装置Eletromagnetichydraulicactuator电动球阀阀mortoroperatedvalve电动球阀阀motorizedvalve电动球阀截止阀ElectricActuatedStopValves平行式双闸板闸板ElectricDoubleDiskParallelGateValves楔式闸阀ElectricActuatedWedgeGateValves装置Electricactuator电－液动装置Eletrohydraulicactuator电液伺服阀electro-hydraulicservovalve调节弹簧Regulationspring调节阀adjustingvalve调节阀controlvalve调节阀regulatingvalve调节螺套AdjustingboltAdjustingscrew调节圈Adjustingring蝶板Disc蝶阀；瓣阀butterflyvalve蝶阀；瓣阀；拍门；铰链阀flapvalve蝶式缓冲止回阀ButterflyTypeNon-slamCheck蝶式止回阀Butterflyswingcheckvalve定比减压阀Proprutioningpressurereducingvalve定差减压阀Fixeddifferentialreducingvalve定值减压阀Fixedpressurereducingvalve动态特性Dynamiccharacteristics对焊连接阀Buttweldingvalves对夹蝶板阀Waferplatevalves对夹式衬胶蝶阀WaferTypeButterflyValveswithRubberItning对夹式阀门Clampvalves对夹式止回阀WaferCheckValves额定排量Certifiedcapacity额定排量系数Deratedcoefficientofdischarge二通阀Two-wayvalves阀valve阀板valvedeckplate阀板valveplate阀板式活塞泵valvedeckplatetypepistonpump阀板式活塞泵valveplatetypepistonpump阀瓣Disc阀操纵杆valveoperatingrod阀痤槽valveseatrecess阀挡valvegrid阀挡valvepositioner阀挡valvestop阀导杆valvetailrod阀导向器valveguide阀盖bonnet阀盖衬套bonnetbush阀盖垫片bonnetgasket阀杆stem阀杆valverod阀杆valvespindle阀杆端部尺寸Dimmensionofvalvestemend阀杆环stemring阀杆螺母YokebushingYokenut阀杆填料stempacking阀杆头部尺寸Dimensionofvalvestemhead阀簧valvespring阀簧压板valvespringplate阀控水锤泵valve-controlledhydraulicram阀框架valveyoke阀门Valve阀门传动装置valvebandleset阀门和管件ValvesandFittings阀门盘根valvepacking阀门手柄valvehandle阀盘disc阀盘valvedisc阀片Disc阀球valveball阀驱动臂valvedrivingarm阀驱动臂valvemotionarm阀式活塞valvetypepiston阀式活塞valvetypebucket阀室式活塞泵valveboxtypepistonpump阀室式活塞泵（美）valvepottypepistonpump阀抬起装置valveliftingdevice阀体body阀体valvebody
