分析閘閥的優點應用及其分類的介紹

2015-09-18 10:54:57| 發布者: 廣州富山閥門有限公司| 查看: 1548

閘閥的優點
    1、流動阻力小。中國進口閘閥的閥體内部介質通道是直通的,介質成直線流動,流動阻力小。
    2、閘閥的啟閉時較省力。因為無論是開或閉,閘闆運動方向均與介質流動方向相垂直。
    3、閘閥的高度大,啟閉時間長。閘闆的啟閉行程較大,降是通過螺杆進行的。
    4、閘閥的關閉時間長,不易産生水錘現象。
    5、閘閥的通道兩側是對稱的,介質可向兩側任意方向流動,易于安裝,不受方向限制。
    中國閘閥将更廣泛用于水利、機械、造紙、冶金、石化、化工、城建等行業。

閘閥是利用閘闆作為啟閉件,通過閥杆的上下升降來帶動閘闆的升降以達到閥門的開啟和關閉,閘闆的運動方向與流體方向相垂直,閘閥隻能作全開和全關,不能作調節和節流。可分别适用于水、蒸汽、油品、硝酸、醋酸、氧化性介質、尿素等多種介質。
    這個進口閘閥市場按材質分為進口鑄鋼閘閥、進口鑄鐵閘閥、進口不鏽鋼閘閥;
    按法蘭标準可分為進口美标閘閥和進口日标閘閥;
    按連接方式可劃分為進口内螺紋鍛鋼閘閥和進口高溫高壓電站閘閥(焊接閘閥);
    還可按閥闆結構劃分,有用于漿料,洗煤,礦山紙漿的進口刀型閘閥和進口氣動漿液閥,用于石油鑽井等的進口平闆閘閥;
    特殊的閘閥市場還用到水用的進口彈性座閘閥,用于低溫液态天然氣、低溫液态氧氣的進口低溫閘閥,用于瀝青、導熱油等具有保溫保冷的進口夾套保溫閘閥。
