Embodiment Construction
[0015] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0016] to combine Figure 1-4 , figure 1 It is a schematic diagram of the overall structure of the coaxial double electromagnetic gas injection valve with adjustable flow cross-sectional area of the present invention, including valve body 1, main electromagnet, secondary electromagnet, valve stem 7, small valve core 12, T-shaped armature 6, valve Core assembly 11, valve seat 14 four parts. The secondary iron core 2 is connected with the valve body 1 through the upper thread. The main electromagnet mainly consists of an iron core 8 and a coil 9. Both sides of the iron core 8 are provided with annular grooves for arranging the main return spring 10 , and the valve core assembly 11 is arranged under the iron core 8 . The secondary electromagnet is mainly composed of a secondary iron core 2 and a secondary coil 3 . It is characterized in that: the two sides of ...
