查询词典 automatically operated valve

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。

"Kv ·= constant" principle, a sense of freedom laminated springs and valve switching power systems Plug Valves constitute △ P / S =εL S-feeling film work area,ε-spring Hook coefficient, L-valve stroke From this position of valve travel decisions every size of △ P value, if the valve travel position of the Kv and inversely proportional to the G = Kv · a constant value.

&Kv·=常数&原理，自由弹簧和感压膜构成阀门开关动力系统△P/S=εL S—感膜工作面积，ε—弹簧的胡克系数，L—阀行程由此可知阀门的每一个行程位置决定△P值的大小，如果阀行程位的Kv与成反比，则G=Kv·是恒定值。
