Description:

Y14H/Y型直接作用式波纹管减压阀

一、产品详细资料
 
产品型号:Y14H/Y
 
产品名称:直接作用式波纹管减压阀
     Y14H/Y型直接作用式波纹管减压阀 内部采用不锈钢波纹管结构,结构简单耐用,使用于灵敏度要求高,安装空间要求苛刻的管道。连接方式为内螺纹,常用规格有G1/2'',PN1.6MPa。
波纹管式减压阀结构特点和用处:
深圳北泽减压阀于直接作用式波纹管减压阀,主要由阀座、阀瓣钢球、波纹管组合件、弹簧等零件组成,通过调节弹簧设定出口压力,当出口压力减少时阀瓣开度增大,当出口压力达到预定压力时阀瓣开度减小,主要是通过介质的阀后压力作用在波纹管的面积上传感给调节弹簧实现减压、稳压功能。
使用时通过旋转塑料手轮即可调节压力,无需工具调节,连接安装方便.内部结构使用波纹管,密封面带有过滤网保护装置,不容易损坏内部零件,大大提高使用寿命。
