The coil can be electrified for a long time. The sealing performance is good and the valve can achieve zero leakage and has good maintainability.
Description
Technical field
The present invention relates to solenoid valve, particularly relate to two-position three way direct action solenoid valve.
Background technique
The at present domestic product that there is no homogeneous structure, function similar products are generally sliding sealing, easily leak, and working pressure are 1.0MPa after work a period of time, and product work pressure cannot reach 4.5MP, and using scope is limited; External function similar products, small product size is larger, and installs inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of volume little, lightweight, change and
Easy to maintenance, flexible movements are reliable, and without leaking, working pressure is high, the two-position three way direct action solenoid valve of long service life.
The technological scheme adopting is:
Two-position three way direct action solenoid valve, comprises valve body, valve bottom plug, upper cover, shell group, piston group, valve plug group, coil groups, moving iron core, push rod, manual operating device, termination.Valve body is bolted shell group, and shell group is bolted upper cover, and valve bottom plug is threaded in valve body bottom.Manual push rod is housed in described upper cover, the in-built moving iron core of shell group, valve plug group, piston group are equipped with in the runner position of valve body, valve plug group bottom is provided with spring, both ends of the spring is supported respectively valve plug group and spring seat, valve plug group upper end is connected with the conduction push rod that is contained in piston group lower end, and piston group upper end is connected with being contained in moving iron core and installing to the push rod of shell group lower end.Described valve body is provided with runner hole A, runner hole O and tri-runner holes of runner hole P of being communicated with valve flowing channel.The conduction magnetic sheet that coil groups is housed, be connected with coil groups in the shell of described shell group and the wire board being connected with magnetic board, wire board is provided with wiring terminal, and termination is welded on and covers.The described manual operating device upper cover that is threaded, manual operating device upper end is connected with the manual push rod upper end in upper cover, manually push rod lower end be contained in the push rod that moves iron core and be connected.
Valve plug sealing is equipped with in the upper end of above-mentioned valve plug group.
