进口多级降压低噪音调节阀 德国多级降压低噪音调节阀

产品名称：德国进口多级降压低噪音调节阀

进口多级降压低噪音调节阀是在吸收CV3000调节阀技术的基础上研发的实用新型阀门，特殊的阀内件设计可实现阀门在高温高压差工况下达到降噪降压的效果。该系列阀门采用多层套筒结构，套筒层数一般为2～6层，最高压差可达7MPa。原理：当流体介质流经阀体内件时，复杂的节流通道具有较大的阻尼系数，会逐级降低压力和速度，防止对内件的冲蚀。同时声波在节流通道中收缩、膨胀以及摩擦，不断消耗其能量，能很好吸收一定的频率，降低噪音，最大降噪可达30分贝左右。 

进口多级降压低噪音调节阀的泄漏量符合ANSI B16.104标准。调节阀配用多弹簧薄膜执行机构或气缸执行机构，其结构紧凑，输出力大。 

Multi-Stage Pressure Reducing Low-Noise Control Valve 

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.
