      產品名稱:HKG 多級降壓低噪音調節閥
      產品簡介:  

      HKG 多級降壓低噪音調節閥是我廠在吸收CV3000調節閥技術的基礎上自主研發的實用新型閥門,特殊的閥內件設計可實現閥門在高溫高壓差工況下達到降噪降壓的效果。該系列閥門采用多層套筒結構,套筒層數一般為26層,最高壓差可達7MPa。原理:當流體介質流經閥體內件時,復雜的節流通道具有較大的阻尼系數,會逐級降低壓力和速度,防止對內件的沖蝕。同時聲波在節流通道中收縮、膨脹以及摩擦,不斷消耗其能量,能很好吸收一定的頻率,降低噪音,最大降噪可達30分貝左右。

      調節閥的泄漏量符合ANSI B16.104標準。調節閥配用多彈簧薄膜執行機構或氣缸執行機構,其結構緊湊,輸出力大。

      產品符合GB/T42132008標準。

      Multi-Stage Pressure Reducing Low-Noise Control Valve

      HKG Multi-stage pressure reducing low-noise Control Valve is the new type developed on the basic of CV3000 series control valve by our company. The special valve trim parts can reduce the noise and pressure under the condition of high temperature and pressure. it adopts multi-cage whose layers number is 2 to 6, and the max. pressure drops is up to 7MPa. Theory: When the fluid flow across the valve trim, the throttle passage with larger damping coefficient can reduce pressure and velocity to prevent eroding the trim. And the sound wave is consumed the energy and absorbed its frequency after shrinking , expanding and rubbing, the max noise reduction is about 30db lower.

      The leakage complies with the ANSI B16.104 standards. The actuator integrated with simplest mechanisms utilizes a compact yet powerful diaphragm actuator loaded with multiple springs or a cylinder.

      This product complies with the GB/T4213-2008 standards.
