公稱壓力：按質量碳素鋼材質和介質參數(shù)，由表1-3查得：閥門公稱壓力為PN=16MPa。密封面材料：根據(jù)閥門公稱壓力和介質溫度，按表2-3b可選用不銹鋼或硬質合金鋼。驅動方式：本例未提特殊要求，可采用手輪驅動。連接形式：法蘭連接。公稱通徑：根據(jù)介質參數(shù)，烏魯木齊柱塞閥廠家，管材可選用50號質量碳素鋼無縫鋼管，按管子內徑107mm，公稱壓力℃溫度下的許用應力，管子壁厚選定為14mm，則管子計算外徑為DW=107+2×14=135mm，采用外徑為140mm，此時公稱通徑為DN=125mm。閥門的公稱直徑應與管子相同。閥門的類型與型號：油品管道應選用閘閥。根據(jù)閥門參數(shù)表的參數(shù)，當PN=16MPa時，截止閥**大公稱通徑為40mm，而同樣壓力等級下閘閥的**大公稱通徑為200mm，因此也應選用閘閥。按閘閥參數(shù)表，在PN16MPa下的碳鋼手輪法蘭閘閥型號有Z41H-160和Z41Y-160兩種。但前者的**大公稱通徑為40mm，而后者的**大公稱通徑為200mm，故應選用Z41Y-160型閘閥，其閥門密封面為硬質合金。所選用的呋喃全稱為：明桿楔式單閘板閘閥（Z41Y-160DN125）。八，烏魯木齊柱塞閥廠家、自動閥門的選用返回頁首自動閥門的選用與一般閥門一樣，除要考慮經(jīng)濟合理性、經(jīng)久耐用外，烏魯木齊柱塞閥廠家，還要求自動閥門的動作靈敏、可靠、調節(jié)準確等性能。庫爾勒止回閥廠家。。。烏魯木齊柱塞閥廠家</p><div

脈沖式蒸汽疏水閥也具有體積小、重量輕的特點，但結構復雜，制造精度要求高、價格貴。⑷疏水閥的選用由于各種型式的蒸汽疏水閥各有不同的優(yōu)缺點和不同的適用條件，因此多年以來各種型式的蒸汽疏水閥長期并存，應用于各種工業(yè)管道中。在諸多型式的疏水閥中，必須正確地選擇適合某一系統(tǒng)中的疏水閥，因為這對系統(tǒng)的正常運行影響很大，選擇恰當可提高熱效率和節(jié)省燃料。正確的選型應按下列標準：①蒸汽疏水閥的公稱壓力及工作溫度應大于或等于蒸汽管道及用汽設備的**高工作壓力及**高工作溫度。②蒸汽疏水閥必須區(qū)別類型，按其工作性能、條件和凝結水排放量進行選擇，不得只以蒸汽疏水閥的公稱通徑作為選擇依據(jù)。③在凝結水回收系統(tǒng)中，若利用工作背壓回收凝結水時，應選用背壓率較高的蒸汽疏水閥（如機械型蒸汽疏水閥）。④當用汽設備內用汽不得積存凝結水時，應選用能連續(xù)排出飽和凝結水的蒸汽疏水閥（如浮球式蒸汽疏水閥）。⑤在凝結水回收系統(tǒng)中，用汽設備用汽排出飽和凝結水，又用汽及時排除不凝結性氣體時，應采用能飽和水的蒸汽疏水閥與排氣裝置并聯(lián)的疏水裝置或采用同時具有排水、排氣兩種功能的蒸汽疏水閥（如特經(jīng)理型蒸汽疏水閥）。⑥當用汽設備工作壓力經(jīng)常波動時。烏魯木齊蝶閥閥門廠家阿圖什立臥兩用止回閥廠家。</p><div

style="text-indent:25px">閘閥原理圖截止閥原理圖解釋：閘閥的通流體部分也是和直管是一樣的，但在管內容設了個閘板，如果把這個閘板設法提起來這個門就全開了，而截止閥流體是在閥內轉了180度的彎，通常流體是從閥的一側進和入閥后轉了個90度的角向上流，流到閥體的上部后又轉了個90度流出去，就在流體在閥內向上流的出口處加了個蓋，這個蓋蓋上門就關了，把這個蓋打開閥就開了。從流向上：截止閥是低進高出，從外觀看有明顯的管道不在一相水平線上。閘閥流道在一個水平線上。閘閥的行程比截止閥的要大。閘閥流向圖截止閥流向圖</p><p> 縮口閘閥阻力系數(shù)大一些。截止閥的阻力系數(shù)比閘閥大得多，一般在4～7之間。Y型截止閥（直流式）阻力系數(shù)**小，在～2之間。鍛鋼截止閥阻力系數(shù)**大，甚至高達8。止回閥的阻力系數(shù)視結構而定：旋啟式止回閥通常約為～2，其中多瓣旋啟式止回閥的阻力系數(shù)較大；升降式止回閥阻力系數(shù)**大，高達12。旋塞閥的阻力系數(shù)小，通常約為～。隔膜閥的阻力系數(shù)一般在。蝶閥的阻力系數(shù)小，一般在。球閥的阻力系數(shù)**小，一般在。上述閥門的阻力系數(shù)是閥門全開狀態(tài)下的數(shù)值。閥門通徑的選用，應考慮到閥門的加工精度和尺寸偏差，以及其它因素影響。閥門通徑應有一定的富裕量，一般為15%。在實際的工作中，閥門通徑隨工藝管線的通徑而定。六、根據(jù)工況條件和工藝操作綜合確定閥門的結構型式返回頁首1.工藝要求氨對銅有腐蝕作用，不能選用銅材質制作的閥門。在介質中含有氨的工藝流程中，截止閥的結構與一般閥門不同，其密封面是用巴氏合金制作的。雙流向的管線應選用無方向性的閥門。在煉油廠，重質油管停止運行后，要用蒸汽反向吹掃管線，以防重油凝固堵塞管線，因而不宜采用截止閥。因為介質反向流入時，容易沖蝕截止閥密封面，應選用閘閥為佳。對某些有析晶或含有沉淀物的介質。阿圖什閘閥廠家阿克蘇球型止回閥廠家。</p><div

一、根據(jù)流量特性選用閥門閥門啟閉件及閥門流道的形狀使閥門具備一定的流量特性。在選擇閥門時，必須考慮到這一點。1.截斷和接通介質用閥門通常選擇流阻較小、流道為直通式的閥門。這類閥門有閘閥、截止閥、柱塞閥。向下閉合式閥門，由于流道曲折，流阻比其它閥門高，故較少選用。但是，在允許有較高流阻的場合，也可選用閉合式閥門。2.控制流量用的閥門通常選擇易于調節(jié)流量的閥門。如調節(jié)閥、節(jié)流閥、柱塞閥，因為它的閥座尺寸與啟閉件的行程之間成正比例關系。旋轉式（如旋塞閥、球閥、蝶閥）和撓曲閥體式（夾管閥、隔膜閥）閥門也可用于節(jié)流控制，但通常*在有限的閥門口徑范圍內適用。在多數(shù)情況下，人們通常采用改變截止閥的閥瓣形狀后作節(jié)流用。應該指出，用改變閘閥或截止閥的開啟高度來實現(xiàn)節(jié)流作用是極不合理的。因為，管路中介質在節(jié)流狀態(tài)***速很高，密封面容易被沖刷磨損，失去切斷密封作用，同理，用節(jié)流閥作為切斷裝置也是不合理的。3.換向分流用閥門根據(jù)換向分流需要，這種閥可有三個或者更多的通道，適宜于選用旋塞閥和球閥。大部分換向分流用的閥門都選用這類閥門。在某些情況下，其它類型的閥門，用兩只或更多只適當?shù)叵嗷ミB接起來。庫爾勒立式止回閥廠家。烏魯木齊柱塞閥廠家</p><p

會明顯地降低螺栓的負荷，對受力很大的法蘭連接就可能產(chǎn)生泄漏。3.焊接連接這種連接適用于各種壓力和溫度，在較苛刻的條件下使用時，比法蘭連接更為可靠。但是焊接連接的閥門拆卸和重新安裝都比較困難，所以它的使用限于通常能長期可靠地運行，或使用條件苛刻、溫度較高的場合。如火力發(fā)電站、核能工程、乙烯工程的管道上。公稱通徑在50mm以下的焊接閥門通常具有焊接插口來承接帶平面端的管道。由于承插焊在插口與管道間形成縫隙，因而有可能使縫隙受到某些介質的腐蝕，同時管道的振動會使連接部位疲勞，因此承插焊接的使用受到一定的限制。在公稱條件較大，使用條件苛刻，溫度較高的場合，閥體常采用坡口對焊連接，同時，對焊縫有嚴格要求。三、根據(jù)介質性能選用閥門返回頁首許多介質都有一定的腐蝕性；同一種介質，隨著溫度、壓力和濃度的變化，其腐蝕性也不同。因此，應根據(jù)材料耐腐蝕性能，選擇適宜于該介質的閥門。1.鑄鐵閥門⑴灰鑄鐵閥門適用于水、蒸汽、石油產(chǎn)品、氨能在絕大多數(shù)的醇、醛、醚、酮、脂等腐蝕性較低的介質中工作。它不適于鹽酸、硝酸等介質。但能用于濃***中，這是因為濃***能對其金屬表面產(chǎn)生一層鈍化膜。以阻止?jié)?**對鑄鐵的腐蝕。烏魯木齊柱塞閥廠家</p><p
