产品详情

一、结构及用途 Structure and purpose

该阀用于空调系统供/回水之间以平衡压差的阀门，可提高系统的利用率，保持压差的准确恒定值，并可限度地降低系统的噪音，以及过大压差对设备造成的损坏。该阀于其它平衡阀，它不需其它执行机械，靠介质自身的压力差来达到系统平衡之功能，节约能源及安装场地空间。

A valve used between water supply/back of an air conditioning system order to balance the pressure differential and able to raise the system's utility．keep the pressure differential at an accurately constant value and to lower ths system's noise and the damage to the equipment due to an extra-big pressure differential to the utmost extent．1t is superior to the other balancing valves，needs no other execution machinery.gets the system balanced completely depend-ing on the pressure differential of the medium's own and saves energy and the installation space．
