Posi-flate流量控制阀又称400X流量控制阀,是一种采用高精度先导方式控制流量的多功能阀门。适用于配水管需控制流量和压力的管路中,保持预定流量不变,将过大流量限制在一个预定值,并将上游高压适当减低,即使主阀上游的压力发生变化,也不会影响主阀下游的流量。其连接方式分为法兰式与螺纹式;焊接式。控制调节方式分为自动与手动。 Posi-flate流量控制阀又称400X流量控制阀,是一种采用高精度先导 1、一改常规节流阀使用孔板或纯机械的减小流域面积的原理,利用相关导阀,zui大限度地减小能量在节流过程中的损失 2、控制灵敏度高,安全可靠,调试简便,使用寿命长。 流量控制阀可在没有外接电源的情况下,自动实现系统的流量平衡。是通过保持孔板(固定孔径)前后压差一定而实现流量限定的,因此,也可称定流量阀。 定流量阀作用对象是流量,能够锁定流经阀门的水量,而不是针对阻力的平衡。他能够解决系统的动态失调问题:为了保持单台制冷机、锅炉、冷却塔、换热器这些设备的率运行,就需要控制这些设备流量固定于额定值;从系统末端来看,为了避免动态调节的相互影响,也需要在末端装置或分支处限制流量。 在设计中应注意的问题,流量控制阀的缺点是在于阀门有zui小工作差的要求,一般产品要求zui小工作压差20KPa,如果安装在zui不利回路上,势必要求循环水泵多增加2米水柱的工作扬程,所以应采取近端安装,远端不安的方法。用户离热源距离大于供热半径的80%时就不要安装这种流量控制阀。 Magna™?
