復(fù)合式過熱蒸汽疏水閥 Combined overheated sream trap 產(chǎn)品介紹:SH系列內(nèi)帶集水倉的倒置桶過熱蒸汽疏水閥專門用來克服過熱,高壓,小負荷等多種不力因素。集水倉存集足夠的凝結(jié)水,保證在整個排放周期能夠保持水封。密封的小杯在集水倉中起密封調(diào)節(jié)作用。 結(jié)構(gòu)特點: 1、耐磨損,耐腐蝕,耐水擊。 2、*的杠桿機構(gòu)將桶提供的力充分放大,可在系統(tǒng)壓力下開啟閥門。 3、排放孔通過水封保護可防止新鮮蒸汽泄漏。桶上的小孔可提供自動排空氣。 4、倒置桶疏水閥不需要專門調(diào)節(jié),凝結(jié)水不會存積造成水擊。 安裝建議:通常在過熱高壓小負荷工況下,在集水管和疏水閥內(nèi)只是極少的凝結(jié)水產(chǎn)生。因此,選擇適當(dāng)?shù)墓艿兰凹艹叽缡钦_使用過熱蒸汽疏水閥的關(guān)鍵。 Introduction:SH inverted bucket steam trap is especially designed to solve the problems of overheating,high pressure and small load.The sufficient condensed water stored in the water storage chamber can ensure the sealing during the whole period of discharging .The small cup play adjustable role in water storage chamber. Structure:1.Boasting excellent abilities to resist abrasiveness,corruption and water 2.Unique lever structure will fully magnify the power provided by bucket.The valve will be opened under system pressure ; 3.Discharging pore which is sealed can protect the fresh steam from leakge.The pore on the bucket can provide automatic gas discharging. 4.The inverted bucket trap does not need special adjustment and the condensed water will not be stored to cause water beating. Suggestions:on installation :Under the overheated pressure,there’s little condensed water produced in the catchment pipelines and trap.Therefore,to choose appropriate pipelines and size of catchment pipelines is the key to correctly use the overheated trap. 主要零件材料和性能參數(shù) Main parts and specifications 主要零部件材料表 Main parts materials | Body 閥體 | 1Cr18NNi9Ti | 性能參數(shù) Performance parameter | SH64P | 6.4MPa | Main valve seat 主閥座 | Tungsten chromium cobalt alloy 鎢鉻鈷合金 | SH100P | 10.0MPa | The duplicate velvet/floats the cup 復(fù)閥、浮杯 | 1Cr18NNigTi | Highest working temperature zui高工作溫度 | 500℃ | 進水管 進氣管 | Stainless Steel 不銹鋼 | Higest pemissible temperature zui高允許溫度 | 技術(shù)參數(shù)表 Technological paramerter date Model 產(chǎn)品型號 | Nominal diameter 公稱通徑(DN) | Connection 連接方式 | Pressure Rating(MPa) 使用壓力 | Max allowable TMP(℃) zui高允許溫度 | Exterma dimensions(mm)外型尺寸 | H | W | CS15Y-64P-SH | 15~25 | Thread螺紋 | 0.01`6.4 | 480 | 300 | 112 | CS45Y-64P-SH | Flange 法蘭 | 480 | 300 | 112 | CS65Y-64P-SH | Socket weld 承插焊 | 480 | 300 | 112 | CS45-100P-SH | Flange 法蘭 | 0.1~10.0 | 420 | 350 | 112 | CS65-100P-SH | Socket weld 承插焊 | 420 | 350 | 112 | 建議的蒸汽主管及支管尺寸 | M | D | H-及水管zui小長度mm | 蒸汽主管尺寸 | 及水管尺寸 mm | 控制升溫 | 自動升溫 | 15 | 15 | 250 | 710 | 20 | 20 | 250 | 710 | 25 | 25 | 250 | 710 | 50 | 50 | 250 | 710 | 75 | 75 | 250 | 710 | 100 | 100 | 250 | 710 | 150 | 100 | 250 | 710 | 200 | 100 | 300 | 710 | 250 | 150 | 380 | 710 | 300 | 150 | 450 | 710 | 350 | 200 | 530 | 710 | 400 | 200 | 600 | 710 | 450 | 250 | 685 | 710 | 500 | 250 | 760 | 760 | 600 | 300 | 910 | 910 | 維護與檢修 疏水閥運行期一般為12個月,到期打開出口體清除臟物,清洗濾網(wǎng),如介質(zhì)雜質(zhì)較多,可以酌情提前清洗。疏水閥由于使用過久可能有封閉不嚴現(xiàn)象,這時,要及時更換或維修(如維修:打開出口體,把閥蓋卸下打開,檢查閥片,閥座密封是否磨損。可以用600目金鋼砂混機油在平臺上研磨,達到電二件互為密封為止。) 故障現(xiàn)象 | 可能原因 | 解決方法 | 漏汽 | 1 .閥片、閥座的密封面嚴重磨損; | 研磨密封面,使其達到密封; | 2 .密封面上存有污垢或水銹 | 打開閥蓋清除污垢或水銹 | 3 .閥前無凝結(jié)水、蒸汽過熱 | 關(guān)閉疏水閥前截止閥 | 連續(xù)排水 | 閥蓋沒有擰緊或者閥蓋有泄漏蒸汽直接進入控制,使閥片打不開。 | 旋緊閥蓋或排除泄漏處,可用耐高溫密封膠修補泄漏處 | ◇ 閥門類:【A】安全閥【D】蝶閥 電磁閥【F】放料閥【G】隔膜閥 管夾閥 過濾器【H】呼吸閥【J】 截止閥 減壓閥【P】排泥閥 排氣閥 排污閥 平衡閥【Q】球閥 切斷閥【S】 疏水閥 水力控制閥【T】調(diào)節(jié)閥【X】旋塞閥【Z】閘閥 針型閥 止回閥 柱塞閥 阻火器。
