2W水用黃銅、不銹鋼電磁閥特點：在真空、負壓、零壓時能正常工作，但通徑一般不超過25mm。分布直動式電磁閥：原理：它是一種直動和先導式相結合的原理，當入口與出口沒有壓差時，通電后，電磁力直接把先導小閥和主閥關閉件依次向上提起，閥門打開。當入口與出口達到啟動壓差時，通電后，電磁力先導小閥，主閥下腔壓力上升，上腔壓力下降，Valve Co., Ltd. Shanghai Zhi wide direct-acting solenoid valve, the performance directly affects the performance of the solenoid valve combination valve, which affect the performance of the control rod hydraulic drive technology. Hydraulic drive system during operation of the control rod of this article appeared conditions, its direct-acting solenoid valve head was hot experimental simulation study and using FLUENT software, a theoretical analysis results show: With the coil winding temperature will increase the current increases, the coil temperature is higher than the inner wall the outer wall temperature, the coil temperature is higher than the edge of the intermediate temperature. proposed detection method solenoid valve normal high temperature operation, and can be optimized direct-acting solenoid valve power supply parameters by simulation of thermal state experiment valve head.
