Suction superheat control system consists of electronic expansion valves, pressure sensors, temperature sensors, controller, working hours, the pressure evaporator outlet pressure sensor P1, temperature sensors compressor suction superheat will be passed to controller, controller After signal processing, followed by the output commands acting on the main electronic expansion valve stepper motor to open the valve to the desired location.

吸气过热度控制系统由电子膨胀阀、压力传感器、温度传感器、控制器组成，工作时，压力传感器将蒸发器出口压力P1、温度传感器将压缩机吸气过热度传给控制器，控制器将信号处理后，随后输出指令作用于电子膨胀主阀的步进电机，将阀开到需要的位置。

Electronic expansion valve stepper motor is based on changes in the evaporator outlet pressure P1, the compressor suction Plug Valves superheat degree change in real-time changes in power output, the real-time output of the dynamics of change in time to overcome a variety of working conditions and the main expansion of load condition valve spring force changes, so that the valve opening to meet the evaporator, the demand Reducing Valves for fluid volume and thus the amount of fluid for the evaporator and the evaporator load in real-time match, that is, the electronic expansion valve can be set through the controller, man-made and effective control over superheat.

电子膨胀阀的步进电机是根据蒸发器出口压力P1变化、压缩机吸气过热度变化实时输出变化的动力，这个实时输出变化的动力能及时克服各种工况和各种负荷情况下主膨胀阀变化的弹簧力，使阀的开度满足蒸发器供液量的需求，进而蒸发器的供液量能实时与蒸发负荷相匹配，即电子膨胀阀可通过控制器人为设定，有效的控制过热度。

Bellows Gate Valves However, in large differential pressure operating conditions, evaporation pressure has eased, the evaporator load requirements of the fluid volume decreased, but the actual situation the contrary, in the suction superheat unchanged, due to evaporation pressure has eased, the evaporator outlet pressure be reduced accordingly, pressure changes above and below the diaphragm, causing the main valve opening increases for increased fluid; but in a small pressure operating conditions, evaporation pressure rise, evaporator load demand for fluid volume increased, but the reality is that in the suction gas superheat unchanged, due to evaporation pressure rise, a corresponding increase in the evaporator outlet pressure, pressure difference above and below the diaphragm smaller, so that the main valve opening decreased for the reduction of liquid volume; in variable load is all about.

但在大压差工况下，蒸发压力降低，蒸发器负荷需求的液量减少，但实际情况相反，在吸气过热度不变的情况下，由于蒸发压力降低，蒸发器出口压力相应降低，膜片上下的压差变大，使主阀开度增大，供液量增加；但在小压差工况下，蒸发压力上升，蒸发器负荷需求的液量增多，但实际情况是在吸气过热度不变的情况下，由于蒸发压力上升，蒸发器出口压力相应提高，膜片上下的压差变小，使主阀开度减小，供液量减少；在变负荷下亦如此。
