2W-50电磁阀特点:在真空、负压、零压时能正常工作,但通径一般不超过25mm。分布直动式电磁阀:原理:它是一种直动和先导式相结合的原理
2W水用黄铜、不锈钢电磁阀特点:在真空、负压、零压时能正常工作,但通径一般不超过25mm。分布直动式电磁阀:原理:它是一种直动和先导式相结合的原理,当入口与出口没有压差时,通电后,电磁力直接把先导小阀和主阀关闭件依次向上提起,阀门打开。当入口与出口达到启动压差时,通电后,电磁力先导小阀,主阀下腔压力上升,上腔压力下降,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.
