电磁阀[SOLENOID VALVE]

电磁阀是用来控制流体的自动化基础元件，属于执行器；并不限于液压，气动。电磁阀用于控制液压流动方向，工厂的机械装置一般都由液压钢控制，所以就会用到电磁阀。而通常意义上，国内电磁阀厂家也并不以液压电磁阀为主打，一般多生产二位二通气液用电磁阀。

Solenoid valve is a basic component in automatic flow control, it is actuator but not limited to hydraulic, pneumatic. solenoid valve is mainly used to control the direction of hydraulic flow, machines in plant are usually controled by hydraulic cylinder and thus the solenoid valve is applyed. generally , solenoid valve manufacturers in China not only produce hydraulic solenoid valve, they mainly manufacturer hydraulic-pneumatic combined two way solenoid valve.

电磁阀的工作原理，电磁阀里有密闭的腔，在的不同位置开有通孔，每个孔都通向不同的油管，腔中间是阀，两面是两块电磁铁，哪面的磁铁线圈通电阀体就会被吸引到哪边，通过控制阀体的移动来档住或漏出不同的排油的孔，而进油孔是常开的，液压油就会进入不同的排油管，然后通过油的压力来推动油刚的活塞，活塞又带动活塞杆，活塞竿带动机械装置动。这样通过控制电磁铁的电流就控制了机械运动。

The main working theory of solenoid valve is that there is a fully closed cabinet inside the solenoid valve,with holes in different position. each hole is connected with different hose.the valve is centered with two electric magnets aside, when the power is on, the valve will be pulled to that side.though the movement of the valve, the hole which is connected to the hose will be closed / open, the oil inlet is always open, the hydraulic oil flows to different hoses and push the cylinder piston by its pressure.the piston drives the piston stem and then the equipment into movement. by this means, the mechanical movement can be controled by controling the electricity of solenoid valve.
