閥門專業(yè)術(shù)語(yǔ)及英文注解

閥門行業(yè)術(shù)語(yǔ)強(qiáng)度性能閥門的強(qiáng)度性能是指閥門承受介質(zhì)壓力的能力。閥門是承受內(nèi)壓的機(jī)械產(chǎn)品，因而必須具有足夠的強(qiáng)度和剛度，以保證長(zhǎng)期使用而不發(fā)生破裂或產(chǎn)生變形。密封性能閥門的密封性能是指閥門各密封部位阻止介質(zhì)泄漏的能力，它是閥門最重要的技術(shù)性能指標(biāo)閥門的密封部位有三處：?jiǎn)㈤]件與閥座兩密封面間的接觸處；填料與閥桿和填料函的配和處；閥體與閥蓋的連接處。其中前一處的泄漏叫做內(nèi)漏，也就是通常所說的關(guān)不嚴(yán)，它將影響閥門截?cái)嘟橘|(zhì)的能力。對(duì)于截?cái)嚅y類來說，內(nèi)漏是不允許的。后兩處的泄漏叫做外漏，即介質(zhì)從閥內(nèi)泄漏到閥外。外漏會(huì)造成物料損失，污染環(huán)境，嚴(yán)重時(shí)還會(huì)造成事故。對(duì)于易燃易爆、有毒或有放射的介質(zhì)，外漏更是不能允許的，因而閥門必須具有可靠的密封性能。流動(dòng)介質(zhì)介質(zhì)流過閥門后會(huì)產(chǎn)生壓力損失（既閥門前后的壓力差），也就是閥門對(duì)介質(zhì)的流動(dòng)有一定的阻力，介質(zhì)為克服閥門的阻力就要消耗一定的能量。從節(jié)約能源上考慮，設(shè)計(jì)和制造閥門時(shí)，要盡可能降低閥門對(duì)流動(dòng)介質(zhì)的阻力。啟閉力和啟閉力矩啟閉力和啟閉力矩是指閥門開啟或關(guān)閉所必須施加的作用力或力矩。關(guān)閉閥門時(shí)，需要使啟閉件與發(fā)座兩密封面間形成一定的密封比壓，同時(shí)還要克服閥桿與填料之間、閥桿與螺母的螺紋之間、閥桿端部支承處及其他磨擦部位的摩擦力，因而必須施加一定的關(guān)閉力和關(guān)閉力矩，閥門在啟閉過程中，所需要的啟閉力和啟閉力矩是變化的，其最大值是在關(guān)閉的最終瞬時(shí)或開啟的最初瞬時(shí)。設(shè)計(jì)和制造閥門時(shí)應(yīng)力求降低其關(guān)閉力和關(guān)閉力矩。啟閉速度啟閉速度是用閥門完成一次開啟或關(guān)閉動(dòng)作所需的時(shí)間來表示。一般對(duì)閥門的啟閉速度無嚴(yán)格要求，但有些工況對(duì)啟閉速度有特殊要求，如有的要求迅速開啟或關(guān)閉，以防發(fā)生事故，有的要求緩慢關(guān)閉，以防產(chǎn)生水擊等，這在選用閥門類型時(shí)應(yīng)加以考慮。動(dòng)作靈敏度和可靠性這是指閥門對(duì)于介質(zhì)參數(shù)變化，做出相應(yīng)反應(yīng)的敏感程度。對(duì)于節(jié)流閥、減壓閥、調(diào)節(jié)閥等用來調(diào)節(jié)介質(zhì)參數(shù)的閥門以及安全閥、疏水閥等具有特定功能的閥門來說，其功能靈敏度與可靠性是十分重要的技術(shù)性能指標(biāo)。使用壽命它表示閥門的耐用程度，是閥門的重要性能指標(biāo)，并具有很大的經(jīng)濟(jì)意義。通常以能保證密封要求的啟閉次數(shù)來表示，也可以用使用時(shí)間來表示。類型type按用途或主要結(jié)構(gòu)特點(diǎn)對(duì)閥門的分類型號(hào)model按類型、傳動(dòng)方式、連接形式、結(jié)構(gòu)特點(diǎn)、閥座密封面材料和公稱壓力等對(duì)閥門的編號(hào)連接尺寸connectiondimensions閥門和管道連接部位的尺寸主要外形尺寸generaldimensions閥門的開啟和關(guān)閉高度、手輪直徑以及連接尺寸等連接形式typeofconnection閥門與管道或機(jī)器設(shè)備的連接所采用的各種方式（如法蘭連接\螺紋連接\焊接連接等密封試驗(yàn)sealtest檢驗(yàn)啟閉件和閥體密封副性能的試驗(yàn)上密封試驗(yàn)backsealtest檢驗(yàn)閥桿與閥蓋密封副密封性能的試驗(yàn)密封試驗(yàn)壓力sealtestpressure閥門進(jìn)行密封試驗(yàn)時(shí)規(guī)定的壓力適用介質(zhì)suitablemedium閥門能適用的介質(zhì)適用溫度suitabletemperature閥門適用的介質(zhì)的溫度范圍密封面sealingface啟閉件與閥座（閥體）緊密貼合，起密封作用的兩個(gè)接觸面啟閉件disc用于截?cái)嗷蛘{(diào)節(jié)介質(zhì)流通的一種零件的統(tǒng)稱，如閘閥中的閘板、節(jié)流閥中的閥瓣等填料packing裝入填料函（或填料箱）中，阻止介質(zhì)從閥桿處泄漏的填充物填料墊packingseat支承填料，保持填料密封的零件填料壓蓋gland用以壓緊填料達(dá)到密封的零件支架yoke在閥蓋或閥體上，用于支承閥桿螺母和傳動(dòng)機(jī)構(gòu)的零件連接槽尺寸dimensionofconnectingchannel啟閉件與閥桿裝配連接部位的結(jié)構(gòu)尺寸流道面積flowarea指閥門進(jìn)口端到閥座密封面間的最小截面積（但不是指“簾”面積），用來計(jì)算無任何阻力影響時(shí)的理論排量流道直徑flowdiameter對(duì)應(yīng)于流道面積的直徑流量特性flowcharacteristics穩(wěn)定流動(dòng)狀態(tài)下，當(dāng)進(jìn)口壓力等參數(shù)不變時(shí)，減壓閥的出口壓力與流量的函數(shù)關(guān)系流量特性偏差flowcharacteristicsderivation穩(wěn)定流動(dòng)狀態(tài)下，當(dāng)進(jìn)口壓力等參數(shù)不變時(shí)，減壓閥流量的變化所引起的出口壓力變化值通用閥門generalvalve各工業(yè)企業(yè)中管道上普遍采用的閥門自動(dòng)閥門Self-actingvalve依靠介質(zhì)（液體、空氣、蒸汽等）本身的能力而自行動(dòng)作的閥門驅(qū)動(dòng)閥門Actuatedvalve借助手動(dòng)、電力、液壓或氣壓來操縱的閥門撞擊手輪hammerblowhandwheel利用撞擊作用力以減輕閥門操作力的手輪結(jié)構(gòu)蝸輪傳動(dòng)裝置wormgearactuator用蝸輪機(jī)構(gòu)啟閉或調(diào)節(jié)閥門的裝置氣動(dòng)裝置pneumaticactuator用氣壓力啟閉或調(diào)節(jié)閥門的驅(qū)動(dòng)裝置液動(dòng)裝置hydraulicactuator用液壓力啟閉或調(diào)節(jié)閥門的驅(qū)動(dòng)裝置熱凝結(jié)水排量Hotcondensatecapacity在給定壓差和溫度下疏水閥一/j咐內(nèi)能排出凝結(jié)水的；犀大重量漏汽量Steamloss單位時(shí)間內(nèi)疏水閥漏出新鮮蒸氣的量CQ螺紋球閥CQThreadBallValvesL形三通式L-patternthreewayT形三通式T-patternthreeway安全閥Safetyvalve暗桿閘閥Insidescrewnonrisingstemtypegatevalve百葉窗;閘板shutter百葉窗式擋板louverdamper擺閥式活塞泵swinggatepistonpump保溫式Steamjackettype報(bào)警閥alarmvalve報(bào)警閥;信號(hào)閥;脈沖閥sentinelvalve背壓調(diào)節(jié)閥backpressureregulatingvalve背壓率Rateofbackpressure本體閥桿密封bodystemseal波紋管閥Bellowsvalves波紋管密封閥bellowsealedvalve波紋管密封式Bellowssealtype波紋管平衡式安全閥Bellowssealbalancesafetyvalve波紋管式減壓閥Bellowsreducingvalve波紋管式減壓閥Bellowswealreducingvalve薄膜thinfilm薄膜;隔膜diaphragm薄膜式減壓閥Diaphragmreducingvalve薄型閘閥ThinGateValves不封閉式Unsealtype槽車球閥TankLorryBallValves顫振Flutter常閉式Normallyclosedtype常開式Normallyopentype超低溫閥門Cryogenicvalve超高壓閥門Superhighpressurevalve超過壓力Overpressureofasafetyvalve襯膠隔膜閥rubberlineddiaphragm襯膠截止閥rubberlinedglobevalve垂直板式蝶閥Verticaldisctypebutterflyvalve磁耦合截止閥MagneticCo-operateGlobeValves帶補(bǔ)充載荷的安全閥Supplementaryloadedsafetyvalve帶輔助裝置的安全閥Assistedsafetyvalve單閥碟雙面平行密封閘閥parallelsinglediskgatevalve單口排氣閥SingleOpeningExhaustValves單向閥Non-returnValve單閘板Singlegatedisc單閘板平板閘閥SingleDiscFlatGateValves彈簧薄膜式減壓閥Springdiaphragmreducingvalve彈簧式安全閥Directspringloadedsafetyvalve彈簧座Springplate彈性閘板Flexiblegatedisc當(dāng)量計(jì)算排量Equivalentcalculatedcapacity擋板damper導(dǎo)閥Pilotvalve導(dǎo)向套Valveguidediscguide低溫閥門Sub-zerovalve低壓閥門Lowpressurevalve底閥bottomvalve底閥Footvalve電磁動(dòng)裝置Eletromagneticactuator電磁閥magneticvalve電磁閥solenoidvalve電磁－液動(dòng)裝置Eletromagnetichydraulicactuator電動(dòng)球閥閥mortoroperatedvalve電動(dòng)球閥閥motorizedvalve電動(dòng)球閥截止閥ElectricActuatedStopValves平行式雙閘板閘板ElectricDoubleDiskParallelGateValves楔式閘閥ElectricActuatedWedgeGateValves裝置Electricactuator電－液動(dòng)裝置Eletrohydraulicactuator電液伺服閥electro-hydraulicservovalve調(diào)節(jié)彈簧Regulationspring調(diào)節(jié)閥adjustingvalve調(diào)節(jié)閥controlvalve調(diào)節(jié)閥regulatingvalve調(diào)節(jié)螺套AdjustingboltAdjustingscrew調(diào)節(jié)圈Adjustingring蝶板Disc蝶閥；瓣閥butterflyvalve蝶閥；瓣閥；拍門；鉸
