Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
The electromagnetism pilot head of pesticide sprayer as shown in Figure 1, including base 1, first guide bracket 2, plunger tube
3, dynamic iron core 4, static iron core 5 and coil block 6, base 1 is respectively equipped with input port 11 and delivery outlet
12, it is communicated with the fluid passage 13 of input port 11 and delivery outlet 12, plunger tube 3, elder generation in base 1
Guide bracket 2 and base 1 are the most fixing to be connected, specifically, in order to easy for installation, quick,
Plunger tube 3 is connected by pressing plate 7 is fixing with first guide bracket 2.Be movably set with in plunger tube 3 dynamic iron core 4,
Being fixedly installed static iron core 5, coil block 6 is arranged at the outside of plunger tube 3.
Be provided with dividing plate 21 in first guide bracket 2, dynamic iron core 4 between static iron core 5 and dividing plate 21, quiet ferrum
Core 5 is provided with pressure release passage 51 vertically, and the top of dynamic iron core 4 is provided with and pressure release passage 51 corresponding matching
Sealing-plug 41, support between bottom and the plunger tube 3 of dynamic iron core 4 and be provided with dynamic iron core spring 8；Base 1
Inside it is provided with and the piston 9 of fluid passage 13 corresponding matching, between piston 9 and dividing plate 21, supports being provided with piston
Spring 10, piston 9, base 1, is formed with valve pocket A, on piston 9 between first guide bracket 2 and dividing plate 21
