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。口徑較大時(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(guò)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(guò)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。伊犁船用閥門哪家好庫(kù)爾勒消聲止回閥廠家。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="烏魯木齊塑料閥門哪家好,閥"

其耐蝕性也不相同。塑料襯里的耐蝕性與上述塑料閥門中的相應(yīng)塑料相同。但選用時(shí)，應(yīng)考慮塑料襯里閥門中使用的其它材料的耐蝕性能。⑽橡膠襯里閥門橡膠較軟，因此很多閥門采用橡膠做襯里，以提高閥門的抗蝕性能和密封性能。隨橡膠種類的不同，其耐蝕性差異較大。經(jīng)過(guò)硫化的天然橡膠能耐非氧化性酸、堿、鹽的腐蝕，但不耐強(qiáng)氧化劑，如硝酸、鉻酸、濃***的腐蝕，也不耐石油產(chǎn)品和某些有機(jī)溶劑的腐蝕。因此，天然橡膠被合成橡膠逐漸代替。合成橡膠中的丁腈橡膠耐油性能好，但不耐氧化性酸、芳烴、脂、酮、醚等強(qiáng)溶劑的腐蝕；氟橡膠耐蝕性能優(yōu)異，能耐各類酸、堿、鹽、石油產(chǎn)品、烴類等，但耐溶劑性不及氟塑料；聚醚橡膠可用于水、油、氨、堿等介質(zhì)。⑾鉛襯里閥門鉛屬活性金屬，但因材質(zhì)軟，常用作特殊閥門的襯里。鉛的腐蝕產(chǎn)物膜是很強(qiáng)的保護(hù)層，它是耐***的有名材料，在磷酸、鉻酸、碳酸及中性溶液、海水等介質(zhì)中具有較高的耐蝕性能、但不耐堿、鹽酸的腐蝕，也不適于在它們的腐蝕產(chǎn)物中工作。四、根據(jù)溫度和壓力選用閥門返回頁(yè)優(yōu)先用閥門除了考慮介質(zhì)的腐蝕性能、流量特性、連接形式外，介質(zhì)的溫度和壓力是重要的參數(shù)。</p><p> 并能在進(jìn)口壓力及流量變動(dòng)時(shí)，利用本身介質(zhì)能量保持出口壓力基本不變的閥門。減壓閥分直接作用式和先導(dǎo)式，見圖1-37～圖1-40.⑴直接作用式直接作用式減壓閥是用壓縮彈簧、重物或重力杠桿以及壓縮空氣加載。通過(guò)膜片、活塞或波紋管直接進(jìn)行壓力控制的閥門。這種閥門結(jié)構(gòu)簡(jiǎn)單、耐用。在比較惡劣的工況下，只要維護(hù)得當(dāng)，也能有很長(zhǎng)的壽命。雖然直接作用式的壓力調(diào)節(jié)不像先導(dǎo)式那么精確，但是造價(jià)低?？梢?**地用于不必要做精確控制的場(chǎng)合。常用的直接作用式減壓閥按結(jié)構(gòu)形式分有：彈簧薄膜式減壓閥、活塞式減壓閥、波紋管式減壓閥和杠桿式減壓閥。彈簧薄膜式減壓閥是采用膜片作敏感元件來(lái)帶動(dòng)閥瓣運(yùn)動(dòng)的減壓閥。它的靈敏度高，宜用于溫度和壓力不高的水和空氣介質(zhì)管道上?；钊綔p壓閥是采用活塞作敏感元件來(lái)帶動(dòng)閥瓣運(yùn)動(dòng)的減壓閥。由于活塞在汽缸中承受的摩擦力較大，靈敏度不及薄膜式減壓閥。因此，適用于承受溫度、壓力較高的以蒸汽和空氣等為工作介質(zhì)的管道和設(shè)備上。波紋管式減壓閥是采用波紋管作敏感元件來(lái)帶動(dòng)閥瓣運(yùn)動(dòng)的減壓閥。它宜由于介質(zhì)參數(shù)不高的蒸汽和空氣等潔凈介質(zhì)的管道上。不能用于液體的減壓。更不能用于含有固體顆粒介質(zhì)的管道上。因此。庫(kù)爾勒立式止回閥廠家。</p><div
