空燃比控制机构的开发——(田草川等),工业加热,87/11,№.6,31～36(日文) 在煤气烧嘴空燃比控制方面,最普遍使用的是均压阀的控制方式。它靠导压管把送入烧嘴的空气的压力引到装在煤气管道的膜式均压阀膜片的上侧,而把送入烧嘴的煤气的压力引到膜片的下侧,借此使作用在膜片上的空气和煤气的压力经常处于平衡来把空燃比调节在一定值。这种方式控制精度
Development of air-fuel ratio control mechanism - (Tetsugawa et al.), Industrial Heating, 87/11, No. 6, 31-36 (Japanese) In the control of the air-fuel ratio of the gas burner, the control method of the pressure equalizing valve . The pressure of the air fed into the burner is led to the upper side of the diaphragm of the membrane pressure equalizing valve installed in the gas pipe by the pressure guiding pipe while the pressure of the gas sent to the burner is led to the lower side of the diaphragm, By this, the pressure of air and gas acting on the diaphragm is constantly balanced to adjust the air-fuel ratio to a certain value. This method controls the accuracy
