The 4th innovative point of the present invention is：Two conducting wire weld of coil uses to be staggered and welds and use polyfluortetraethylene pipe
Butt welding point is protected between two parties, is effectively avoided two weldering cusps are just opposite from piercing through the conducting of two conducting wires, is caused electromagnetic valve coil
Short circuit problem.
The present invention has the advantages that：
The normally opened fuel solenoid valve of two-bit triplet of the present invention has flow control accurate, and cut-in voltage is low, good airproof performance, resists three
The advantages that anti-ability is strong, insulating properties is reliable, the leading technology in the same industry are horizontal.
