Embodiment 1
[0016] like Figure 1-2 As shown, a high temperature resistant electromagnetic valve includes: electromagnetic part 1, heat dissipation pipe 2, valve stem 3, ventilation pipe 4, Peltier module 5, valve seat 6, valve disc 7, pipe joint 8;
[0017] The electromagnetic part 1 includes: an outer shell 11, an inner shell 12, an electromagnetic coil 13, an upper stop 14, a lower stop 15, a return spring 16, a return push rod 17, and an armature 18;
[0018] The outer casing 11 is sleeved on the outer periphery of the inner casing 12, and an electromagnetic coil 13 is installed between the two. A top stop 14 is arranged on the opening of the upper end of the outer casing 11, and the lower end of the top stop 14 extends into the outer casing. 11, and block the upper end of the inner casing 12, the upper stop seat 14 is equipped with a return spring 16 and a return push rod 17 for pushing the armature 18 to the initial position, and the lower end of the inner casing 12 is fixedly set ...
Embodiment 2
[0029] The difference from Embodiment 1 is that, as Figure 4 As shown, the structure of the ventilation pipe 104 is different, and other components and connection methods are the same as those of the first embodiment, so this embodiment will not be repeated, and the working principle will not be repeated at the same time;
[0030] The ventilation pipe 04 is arranged on the edge of the pipe wall in the heat dissipation pipe 02. The ventilation pipe 04 is a plurality of spiral pipes, which are close to the inner wall of the heat dissipation pipe 02 and spiral upward until passing through the bottom of the electromagnetic part 01 and turning vertically. Set, until the through hole 0181 passing through the armature 1018 converges into a pipeline and continues to extend to the bottom end of the return push rod 1017, the spiral setting of the multiple pipelines of the air pipe 104 prolongs the gas flow path, further making the gas Before entering the vent tube-04 in the chamber-019...
