三、進口蒸汽電磁閥工作原理：

進口不銹鋼蒸汽電磁閥采用一次開閥或二次開閥連，主閥和導閥使電磁力和壓差直接開啟主閥口;當線圈通電時，產生電磁力使動鐵芯和靜鐵芯吸合，導閥口開啟而導閥口設在主閥口上，且動鐵芯與主閥芯連在一起，此時主閥上腔的壓力通過導閥口卸荷，在壓力差和電磁力的同時作用下使主閥芯向上運動，開啟主閥介質流通;當線圈斷電時電磁力消失，此時動鐵芯在自重和彈簧力的作用下關閉導閥孔，此時介質在平衡孔中進入主閥芯上腔，使上腔壓力升高，此時在彈簧復位和壓力的作用下關閉主閥，介質斷流;結構合理，動作可靠。

3、 Working principle of inlet steam solenoid valve:

The imported stainless steel steam solenoid valve adopts primary valve or secondary valve connection. The main valve and pilot valve make the electromagnetic force and pressure difference directly open the main valve port; When the coil is electrified, the electromagnetic force is generated to make the moving iron core and the static iron core pull in, the pilot valve port is opened, and the pilot valve port is set on the main valve port, and the moving iron core is connected with the main valve core. At this time, the pressure of the upper chamber of the main valve is unloaded through the pilot valve port, and the main valve core moves upward under the simultaneous action of the pressure difference and the electromagnetic force, so as to open the main valve medium circulation; When the coil is powered off, the electromagnetic force disappears. At this time, the moving iron core closes the pilot valve hole under the action of self weight and spring force. At this time, the medium enters the upper chamber of the main valve core in the balance hole, which increases the pressure in the upper chamber. At this time, the main valve is closed under the action of spring return and pressure, and the medium is cut off; The structure is reasonable and the action is reliable.

耐冷凝：蒸汽管道的冷凝水是影響蒸汽電磁閥動作的重要因素，本閥則不受冷凝水影響。

4、 Performance characteristics of imported steam solenoid valve:

The valve is a pilot type secondary opening solenoid valve which is composed of two parts: the auxiliary valve and the main valve.

Heat resistant: special high temperature resistant electrical materials and sealing materials are used for electromagnetic part and sealing part, and various heat insulation measures are applied;

Wear resistance: reasonable material selection, skillful use of fluid lubrication between valve cup and guide sleeve, reduce wear and improve service life;

Anti condensation: the condensation water of steam pipeline is an important factor affecting the action of steam solenoid valve, while this valve is not affected by condensation water.
