上海阔志阀门有限公司直动电磁阀组成的,电磁阀的性能直接影响组合阀的性能,从而影响控制棒水压驱动技术的运行性能.本文就控制棒水压驱动系统运行过程中所出现的工况,对其直动电磁阀阀头进行了热态实验模拟研究,并运用FLUENT软件进行了理论分析.分析结果表明:随着线圈电流增大线圈温度将会增大,线圈内壁温度高于外壁温度,线圈中间温度高于边缘温度.提出了电磁阀高温条件正常运行的检测方法,并通过阀头热态实验模拟研究可优化直动电磁阀的电源参数. 2W water brass, stainless steel solenoid valve Features: can work in the vacuum, negative pressure, zero pressure, but the path is generally not more than 25mm. Distribution of direct-acting solenoid valve: Principle: It is the principle of a direct-acting and pilot-operated combination of the inlet and outlet when no pressure, the power, the electromagnetic force directly to the pilot valve and the main valve closure member in turn Lift , the valve opens. When the inlet and outlet reaches the starting pressure, the power, the electromagnetic force pilot valve, the main valve chamber under increased pressure, the chamber pressure drops,

2W水用黄铜、不锈钢电磁阀原理：常闭型直动式电磁阀通电时，电磁线圈产生电磁吸力把阀芯提起，使关闭件离远开阀座密封副打开；断电时，电磁力消失，靠弹簧力把关闭元件压在阀座上阀门关闭。（常开型与此相反）

2W水用黄铜、不锈钢电磁阀特点：在真空、负压、零压差时能正常工作，DN50以下可任意安装，但电磁头体积较大。如我公司引进HERION公司技术生产的直动电磁阀可用于1.33×10-4 Two-way solenoid valve to control the liquid is one into two (two are a normally open a normally closed); pneumatic solenoid valve is a reversing into a an exhaust; a hydraulic oil into a back.

2W water at home and abroad with brass, stainless steel solenoid valve from the principle divided into three categories (ie: direct acting, step by step direct-acting, pilot), but from a different valve structure with the principles and materials on The difference is divided into six branches categories (direct-acting diaphragm structure, step by step re-sheet structure, the pilot membrane structure, direct-acting piston structure, step by step direct-acting piston structure, the pilot piston structure).

Direct acting solenoid valves: principle: power, the electromagnetic coil generates an electromagnetic force to the closure member is lifted from the valve seat, the valve opens; when power is off, the electromagnetic force disappears, the spring pressure in the valve closure member, the valve closes.
