截止閥的結(jié)構(gòu)形式:
截止閥閥體的結(jié)構(gòu)形式有直通式、直流式和直角式。直通式是常見的結(jié)構(gòu),但其流體的阻力大。直流式流體阻力較小,多用于含固體顆?;蛘扯却蟮牧黧w。直角式閥體多采用鍛造,適用于較小通經(jīng)、較高壓力的的截止閥。截止閥的安裝與維護(hù)注意事項(xiàng):
1、手輪、手柄操作的截止閥可安裝在管道的任何位置上;2、手輪、手柄及傳動機(jī)構(gòu),不允許作起吊用;3、介質(zhì)的流向應(yīng)與閥體所示箭頭方向一致;注:本公司是上海閥門廠家,的閥門種類調(diào)節(jié)閥,球閥,蝶閥,閘閥,減壓閥,止回閥,疏水閥,截止閥,旋塞閥,閥,節(jié)流閥,水力控制閥等,其中截止閥分為電動截止閥,氣動截止閥,手動截止閥,波紋管截止閥,不銹鋼截止閥等,工程師皆有數(shù)十年經(jīng)驗(yàn),歡迎您業(yè)務(wù)!
