温差为源信号的流量控制器

本文介绍一种温差为源信号的流量控制器．是用于采暖供热系统中调控同轴差速式热量表两个固定式叶轮腔中流量的控制装置。由设置于进．出水流腔体内的一对装有饱和蒸汽工质的密闭腔体通过同轴密封联接的弹性波纹管带动串联于卸流旁路中的节流阀的阀芯相对阀壳滑动．从而改变节流阀的开度，达到用两个流体腔内的温度差间接控制出水流道中的流量，使进、出水流道产生相应的流量差．以达到准确热计量的目的。控制器由机械组件构成，自动运作，不依赖外部能量，工作稳定可靠。

A flow quantity controller with temperature difference as its source signal

The article deals with a kind of flow quantity controller, which employ temperature difference as its source signal, used in the system of collecting heat and providing hot, to control the two definitive impeller speech flow quantity in the co-shaft differential heat meters also. In the equipment,there is a pair of airtight speech, which was designed in the in-and-out container with saturation-steam-mediu m, it can change the width of the throttle valve through the elastic wave pipe to drive the center of the throttle valve sliding, the pipe equip in the same shaft. In this way, we can reach the purpose of controlling the flow quantity with temperature difference, the controller was composed of mechanical accessories, working freely, don't depend on the out source, its working reliability can be trusted.
