也可用作介質(zhì)的換向分流。4.帶有懸浮顆粒的介質(zhì)用閥門如果介質(zhì)帶有懸浮顆粒，較適于采用其啟閉件沿密封面的滑動(dòng)帶有擦拭作用的閥門。如平板閘閥。二、根據(jù)連接形式選用閥門返回頁(yè)首閥門與管路的連接形式有多種，其中**主要的螺紋、法蘭及焊接連接。1.螺紋連接這種連接通常是將閥門進(jìn)出口端部加工成錐管或直管螺紋，使之旋入錐管的螺紋接頭或管道上。由于這種連接可能出現(xiàn)較大的泄漏溝道，故可用密封劑、密封膠帶或填料來(lái)堵塞這些溝道。如果閥體的材料是可以焊接的，螺紋連接后還可進(jìn)行密封焊。如果連接部件的材料是允許焊接，但膨脹系數(shù)差異很大，或者工作溫度的變化幅度較大，螺紋連接部必須*密封焊，螺紋連接的閥門主要是公稱通徑在50mm以下的閥門。如果通徑尺寸過大，連接部的安裝和密封十分困難，新疆黃銅絲扣排氣閥廠家。為了便于安裝和拆卸螺紋連接的閥門，在管路系統(tǒng)的適當(dāng)位置可用管接頭。公稱通徑在50mm以下的閥門可使用管套節(jié)作為管接頭，管套節(jié)的螺紋將連接的兩部連在一起。2.法蘭連接法蘭連接的閥門，新疆黃銅絲扣排氣閥廠家，其安裝和拆卸都比較方便，但是比螺紋連接的笨重，相應(yīng)價(jià)格也高，新疆黃銅絲扣排氣閥廠家。故可適用于各種通徑和壓力的管道連接。但是，當(dāng)溫度超過350℃時(shí)，由于螺栓、墊片和法蘭蠕變松弛。庫(kù)爾勒立臥兩用止回閥廠家。新疆黃銅絲扣排氣閥廠家</p><div

1.止回閥的選用止回閥的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止反方向流動(dòng)。常用的止回閥分升降式和旋啟式兩種（見圖1-28～圖1-32）。在高壓和小口徑的設(shè)備或管道上，通常選用升降式止回閥。要求壓力降小的管道，不宜選用升降式止回閥，因其流阻大，而應(yīng)選用蝶式止回閥或旋啟式止回閥。在壓力波動(dòng)大和有特殊要求的管道上。為了防止閥瓣產(chǎn)生水錘而損壞，應(yīng)選用有緩沖裝置的旋啟式止回閥?？趶捷^大時(shí)，選用多瓣旋啟式止回閥。在鍋爐給水泵的出口處，應(yīng)選用**的空排止回閥，以防止介質(zhì)倒流、提高泵的效率。用于水泵吸入管底部的止回閥應(yīng)選用底閥。普通的旋啟式止回閥或升降式止回閥應(yīng)盡量避免口徑過大。為了以**小的流速使止回閥瓣全開或開到合適位置，在某些使用情況下，安裝止回閥的口徑必須比相應(yīng)的管子的口徑要小一些。為了滿足各種用途的需要，止回閥也有多種多樣，如：球形止回閥。螺紋升降式截止止回閥、工作無(wú)沖擊的旋啟式止回閥、斜瓣止回閥、圓錐隔膜式止回閥等。根據(jù)介質(zhì)的不同，閥瓣可以全部用金屬制作，也可在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面、熱噴涂其他合金材料。2.減壓閥的選用減壓閥是通過啟閉件的節(jié)流，將進(jìn)口壓力降至某一個(gè)需要的出口壓力。</p><p> 會(huì)明顯地降低螺栓的負(fù)荷，對(duì)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(shí)，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(zhǎng)期可靠地運(yùn)行，或使用條件苛刻、溫度較高的場(chǎng)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(lái)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(zhì)的腐蝕，同時(shí)管道的振動(dòng)會(huì)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(chǎng)合，閥體常采用坡口對(duì)焊連接，同時(shí)，對(duì)焊縫有嚴(yán)格要求。三、根據(jù)介質(zhì)性能選用閥門返回頁(yè)首許多介質(zhì)都有一定的腐蝕性；同一種介質(zhì)，隨著溫度、壓力和濃度的變化，其腐蝕性也不同。因此，應(yīng)根據(jù)材料耐腐蝕性能，選擇適宜于該介質(zhì)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(zhì)中工作。它不適于鹽酸、硝酸等介質(zhì)。但能用于濃***中，這是因?yàn)闈?**能對(duì)其金屬表面產(chǎn)生一層鈍化膜。以阻止?jié)?**對(duì)鑄鐵的腐蝕。烏魯木齊立式止回閥廠家。</p><div

脈沖式蒸汽疏水閥也具有體積小、重量輕的特點(diǎn)，但結(jié)構(gòu)復(fù)雜，制造精度要求高、價(jià)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(diǎn)和不同的適用條件，因此多年以來(lái)各種型式的蒸汽疏水閥長(zhǎng)期并存，應(yīng)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?yàn)檫@對(duì)系統(tǒng)的正常運(yùn)行影響很大，選擇恰當(dāng)可提高熱效率和節(jié)省燃料。正確的選型應(yīng)按下列標(biāo)準(zhǔn)：①蒸汽疏水閥的公稱壓力及工作溫度應(yīng)大于或等于蒸汽管道及用汽設(shè)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(jié)水排放量進(jìn)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(jié)水回收系統(tǒng)中，若利用工作背壓回收凝結(jié)水時(shí)，應(yīng)選用背壓率較高的蒸汽疏水閥（如機(jī)械型蒸汽疏水閥）。④當(dāng)用汽設(shè)備內(nèi)用汽不得積存凝結(jié)水時(shí)，應(yīng)選用能連續(xù)排出飽和凝結(jié)水的蒸汽疏水閥（如浮球式蒸汽疏水閥）。⑤在凝結(jié)水回收系統(tǒng)中，用汽設(shè)備用汽排出飽和凝結(jié)水，又用汽及時(shí)排除不凝結(jié)性氣體時(shí)，應(yīng)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(shí)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(dāng)用汽設(shè)備工作壓力經(jīng)常波動(dòng)時(shí)。烏魯木齊黃銅絲扣過濾器球閥哪家好。烏魯木齊旋塞閥報(bào)價(jià)</p><p
