High-precision carbon tank electromagnetic valve

The utility model discloses a high-precision carbon tank electromagnetic valve which comprises a shell, a coil framework arranged in the shell and an armature which is arranged in an inner cavity of the coil framework and can move up and down, and an air inlet pipeline and an air outlet pipeline which are communicated with each other are arranged on the shell. One end of the armature blocks the butt joint of the air inlet pipeline and the air outlet pipeline so as to control connection and disconnection of the air inlet pipeline and the air outlet pipeline, and the other end of the armature is provided with an ejection spring. A metal sleeve is arranged in an inner cavity of the coil framework in a sleeved mode, and the surface of the armature is coated with a wear-resistant coating. The carbon tank electromagnetic valve is high in precision, can realize adjustment of multiple opening amplitudes, and can be widely applied to the field of carbon tank electromagnetic valves. 本实用新型公开了一种高精度碳罐电磁阀，包括壳体，置于壳体内的线圈骨架，置
