聯(lián)系我時，請告知來自 泵閥商務(wù)網(wǎng)焊接止回閥啟閉件靠介質(zhì)流動和力量自行開啟或關(guān)閉，以防止介質(zhì)倒流的方向流動，以防止發(fā)生事故。止回閥按結(jié)構(gòu)劃分，可分為升降式止回閥，旋啟式止回閥和蝶式止回閥三種。升降式止回閥可分為立式和臥式兩種。旋啟式止回閥分為單瓣式、雙瓣式和多瓣式三種。蝶式止回閥為直通式、以上幾種止回閥在連接形式上可分為螺紋連接、法蘭連接和焊接三種。
【焊接止回閥】安裝方法以及注意事項
1.在管線中不要使止回閥承受重量，大型的止回閥應(yīng)獨立支撐，使之不受管系產(chǎn)生的壓力影響。
2.安裝時注意介質(zhì)流動的方向應(yīng)與閥體所標(biāo)箭頭方向*。
3.升降式垂直瓣止回閥應(yīng)安裝在垂直管道上。
4.升降式水平瓣止回閥應(yīng)安裝在水平管道上。
