  • 风量调节阀主要的应用方式
  • 本站编辑:杭州逸捷暖通设备有限公司发布日期:2022-01-18 17:32 浏览次数:

风量调节阀,为机械式自力装置,一般使用在需要定风量的通风空调系统中。风量调节阀风量控制不用其他的力,它是用风管内气流力来进行控制阀门的位置,这样就让在整个压力差区域内把气流一直在预先设定的流量上。  (一)、在变风量空调系统中的应用  

在变风量空调系统中,通常外区使用变风量手段,内区使用定风量手段,在一个风量、风压持续改变的送风系统中,内区定风量控制是一定要风量调节阀的。  

(二)、在净化空调系统中的应用  

在净化空调系统中保持洁净房间的正压值非常关键,在排风以及送排风系统中添加风量调节阀,就可以有效确保洁净房间的正压值。清理手术室手术进行时以及不进行时都要让手术室为正压,手术进行时新风量能确保正压想要的新风量加人员需要新风量,手术不进行时新风量仅仅确保正压想要的新风量,因此新风管上的风量调节阀是不可减少的。

Air volume control valve, for mechanical self-reliance device, generally used in the need for constant air volume ventilation and air conditioning system. Air volume control valve air volume control without other forces, it is to control the position of the valve with the air flow force in the air duct, so that the air flow has been in the pre-set flow in the whole pressure difference area. (1) Application in vAV air conditioning system

In the variable air volume air conditioning system, the outer area usually uses variable air volume means, and the inner area uses constant air volume means. In a supply air system with constant air volume and wind pressure changing, the constant air volume control in the inner area must be the air volume control valve.

(two), in the application of purification air conditioning system

It is very critical to maintain the positive pressure value of clean room in the purification air conditioning system. Adding the air volume control valve in the exhaust and air supply and exhaust system can effectively ensure the positive pressure value of clean room. Clean up the operating room when the operation is carried out and when the operation is not carried out, the operating room should be positive pressure. When the operation is carried out, the new air volume can ensure the new air volume desired by the positive pressure plus the new air volume needed by the personnel. When the operation is not carried out, the new air volume only ensures the new air volume desired by the positive pressure, so the air volume regulating valve on the fresh air pipe is not able to be reduced.
