空调系统

Constant Flow Valve and the constant flow regulating valve are different: there is only one fixed flow valve valve from the valve directly feel before and after the differential pressure valve, the implementation of change in valve resistance action can be "direct action type variable resistance valve "It should not regulate the flow line, so the use of Constant Flow Valve can not be implemented to change the total flow of energy to run, and this set the flow valve as there are no imports of expensive, in the past, domestic heating systems seldom used, and only at some central air conditioning system to see.

定流量阀和恒流量调节阀不同的是：定流量阀只有一个阀瓣，由这个阀瓣直接感受阀门的前后差压，执行改变阀门阻力的动作，可成为"直动式变阻力阀"，它不能在线调节流量，因此使用定流量阀无法实施改变总流量的节能运行，而且这种定流量阀国内没有，进口的价格昂贵，以往国内的供暖系统很少采用，只有在一些中央空调系统中见到。
