YB43X固定比例式减压阀

 

YB43X固定比例式减压阀,是一种等比例减低流经介质压力的调节阀。通常用于高层建筑、泵站及消防系统,既能减动压又能减静压,减压比例精确。该阀结构简单,选材优质,价格低廉,性能可靠。参考比例有:2:1、3:1、4:1、3:2、5:2等,如客户有特殊要求,可在订单中说明。比例式减压阀主要由阀体、进口法兰、活塞、大缸套、小缸套、出口法兰及O型圈、密封垫等零件组成。比例式减压阀是利用阀内浮动活塞两端不同的截面积构成了阀前与阀后的压力差,改变阀后的压力达到减压目的。比例式减压阀结构独特、性能优越、流量大、开关平稳、无噪声、减压比例稳定、即“减动压”又“减静压”,并且有减少乃至消除“水锤”现象对管件与供水器具的破坏,消除不必要的振动,节约水源保护管网的作用。
