SP45F数字锁定平衡阀一、用途
本阀门是一种平衡阀，适用于各种液体管路系统，是一种较为理想的新型节能阀门。该阀设有刻度的数字显示，可直观调到任～位置，并可锁定。
该阀主要应用于工业和民用建筑采嗳管路系统。目前在一些管网系统中存在着水力失调问题，平衡阀提供了解决这一问题的手段，用它可以准确的调节压降和流量，用以改善管网系统中液体流动状况，达到管网液体平衡和节约能源的目的。 在双管网工程改造中，应用此阀门仍可节约能源，得到较好的效果。

下图为几种阀门的流量特性曲线，本厂生产的是其中等百分比特性阀门。从曲线图上可知开度一个相等的变化率，则流量的变化率相等，其特点是开度大时流量大，开度小时则流量小。而工程中大都在流量大时应用，等百分比阀门洽洽适用这种要求。根据这一特点，可以自如的予置某一流量(快开阀门和线性阀门则不具备这种功能)而且当需要变化时，还能知道变化量。达到理想状态。
