DZLY型动态阻力平衡阀
国家专利号:200920163405.1(仿造必究)
动态阻力平衡阀适用于集中供热系统中,热网安装此阀使热网很容易达到静态、动态平衡。支持以热源为主动变流量运行。在用户室内在安装恒温阀、温控器等自控装置后又可转换成压差控制实现以用户为主的变流量调节。
动态阻力平衡阀的功能:
动态阻力平衡阀有三种功能:自力式流量阀功能,手动平衡阀功能,自力式压差阀功能。分别实现水泵三种运行模式的不同转换。定流量运行时用自力式流量阀功能;以热源为主变量运行时使用手动平衡阀功能;以用户为主动变流量运行时转换成自力式压差阀功能。避免热网频繁更换阀门,减小供热成本。
动态阻力平衡阀的使用
在热网初调阶段,锁定装置完全打开,该阀按自力式流量控制阀的调节方法进行调节,热用户的流量很快达到平衡状态,发挥了自力式流量控制阀在热网平衡控制上的优势。然后启动锁定装置,该阀变成了一个具有变流量性能的静态平衡阀。由于各个热用户平衡了,循环泵再进行变流量调节时,各用户流量将成等比例的变化,依然保持平衡状态。自力式流量控制阀的定流量和静态平衡阀的变流量,两种功能可以根据具体需要进行转换。分户计量后,接通导压管又可作为自力式压差控制阀使用
动态阻力平衡阀性能与特点:
1.该阀为双阀瓣结构,不平衡力小,结构紧凑;
2.采用外导压结构,拆装方便;
3.阀口、阀芯全铜;
4.采用混压技术,无级调节,控制压差可调范围大;
5.能自动恒定用户压差,吸收外网压力波动,支持被控系统自主调节;
6.控制导管前端安装截断阀,具备自动消除堵塞功能;
7.压差标定精确,调节精度高;
动态阻力平衡阀的材质与寿命
1.阀体:优质灰铸铁;
2.阀体全塑处理防腐;
3.弹簧:不锈钢;
4.膜片:三元乙丙埋纤;
5.阀芯:黄铜;
6.设计寿命:10年以上。
