SP15F Number Lock Balance Valve
Product Name:
SP15F Number Lock Balance Valve
Description:

数字锁定平衡阀SP15F

一、用途

本阀门是一种本平衡阀,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,可直观调到任一位置,并可锁定。

该阀主要应用于工业和民用建筑采暖管路系统。目前在一些管纲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,用以改善管纲系统中液体流动状况,达到管纲液体平衡和节约能源的目的。

在双管纲工程改造中,应用此阀门仍可节约能源,得到较好果。

 

二、主要性能及使用规范

型 号

SP15-

SP45F-10

备 注

试验压力

1.5MPa(15Kgf/cm2)

工作垣力

1MPa(10≤℃Kgf/cn2

工作温度

≤120℃

适用介质

安 装

使用范围

管纲系统的主干、分支干、室内供水干管、
分支立管以及多台锅炉

左图为在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。从曲线图上可知给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火,开度小时流量小。而工程中大都在流晕大时应用,等百分比阀门洽洽适用这各要求。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。
