活塞式流量調節閥


結構特點:

1、中空流線型閥體,直通式軸向對稱流道,斷面為環狀;2、內置曲柄滑塊機構,關閥時先快后慢,不會出現壓力突變和關閥水錘;3、金屬—金屬、金屬—彈性材料的雙重密封結構;4、開度與流量成線性關系,可對介質進行調節。5、節流元件不同型式:扇葉圈式、槽孔式、多噴孔式、環流式等特殊設計,滿足各種不同工況。

產品標準:
1、設計、制造和驗收Q/TD02-2016;2、法蘭連接尺寸GB/T17241.6、GB/T9113;3、壓力試驗GB/T13927。

主要參數:
公稱尺寸:DN200-2400;公稱壓力:PN6-40;密封試驗壓力:1.1PN;殼體試驗壓力:1.5PN;介質溫度:0-80℃;適用介質:水、污水、空氣等。

適宜工況:
1、重力自流輸水管線;2、需要調節管線壓力和流量的工況。
