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(jiàn)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(guò)大。為了以**小的流速使止回閥瓣全開(kāi)或開(kāi)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(mǎn)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。新疆黃銅絲扣閘閥生產(chǎn)</p><p
