这两种疏水器的通径和排水量远较目前热力管道所应用的各种疏水器为大,没有现成的或相近的疏水器可选用。经分析认为,1号疏水器排出的介质为较饱和温度低2～3℃的水,而当介质达到饱和温度时它就关闭,即截断的是饱和水,所以就其实质来看不是阻汽排水器,而是阻饱和水,排非饱和水的设备,这个设备是依介质的温度变化动作的。据此,选用灌有感温液的密封波纹管来感受温度信号和推动阀门。波纹管的位移是有限的,以它来直接带动阀门其排水量是无法满足要求的,所以将阀组成复合式的,其结构见图1。在未供入介质前,受压缩的弹簧将活塞
These two kinds of traps have much larger diameters and displacements than the traps used in the current heat pipe. There is no existing or similar traps available. The analysis shows that the trap 1 discharge medium is lower than the saturation temperature of 2 ~ 3 ℃ water, and when the medium reaches saturation temperature, it is closed, that is cut off is saturated water, so in essence it is not a gas barrier Drainage, but resistance saturated water, non-saturated water discharge equipment, the device is based on medium temperature changes in action. Accordingly, the choice of a sealed sealed bellows filled with temperature fluid to feel the temperature signal and push the valve. The displacement of the bellows is limited, with its direct drive the displacement of the valve is unable to meet the requirements, so the composite valve, the structure shown in Figure 1. The compressed spring will piston before it is fed into the media
