Situation about working a kind of two-way electromagnetic valve of the present invention below in conjunction with accompanying drawing is illustrated, and following embodiment is only
Technology design and the feature of the present invention are described, its purpose is for allowing skilled addressee will appreciate that and implementing the present invention, the most right
Protection scope of the present invention restricts.
Wherein it is desired to explanation, the first described Electromagnetic Control module 2 and the second Electromagnetic Control module 3 and reset
The exchange of position between spring, can cause the first described Electromagnetic Control module 2 and solenoid of the second Electromagnetic Control module 3
Control the first described spool 17 and the axially distinct direction passage of the second spool 18 under "on" position, thus obtain air inlet
13, conducting relation different between gas outlet 14 or air vent 15.
Referring to Fig. 4-9, with under original state, the first described Electromagnetic Control module 2 and the second Electromagnetic Control module 3
Solenoid equal no power time, the first described valve pocket 11 and the discharge chamber 103 of the second valve pocket 12 and outlet chamber 102 are both turned on
In case of be illustrated.
When needing to introduce in gas circuit gas slowly, gas all passes through from the second described valve pocket 12, the second described valve
Chamber 12 is provided with described choke valve 16.Now, the solenoid of the second described Electromagnetic Control module 3 is energized, described in control
Second spool 18 axially elapses, and makes the inlet chamber 101 of the second described valve pocket 12 and outlet chamber 102 turn on, and gas is via air inlet
Mouth 13 is by inlet chamber 101, outlet chamber 102, then enters gas circuit from gas outlet 14.Because the air inlet of the second described valve pocket 12
Chamber 101 is provided with choke valve 16 so that the flow velocity of gas is uniformly slow, and scalable.
When needing that gas is discharged gas circuit, the solenoid no power of the second described Electromagnetic Control module 3, spring promotes
The second described spool 18 axially elapses, and makes the outlet chamber 102 of the second described valve pocket 12 and discharge chamber 103 turn on, gas warp
By gas outlet 14 by outlet chamber 102, discharge chamber 103, then discharge from air vent 15.Because the aerofluxus of the second described valve pocket 12
Mouth 15 is provided with choke valve 16 so that the flow velocity of gas is uniformly slow, and scalable.
When needing to be rapidly introduced in gas circuit gas, the first described Electromagnetic Control module 2 and the second Electromagnetic Control module 3
Solenoid be all energized, first spool the 17, second spool 18 described in control axially elapses, and makes the first described valve pocket 11 He
Inlet chamber 101 and the outlet chamber 102 of the second valve pocket 12 are both turned on, and gas passes through the first valve pocket 11 and the second valve via air inlet 13
The inlet chamber 101 in chamber 12, outlet chamber 102, then enter gas circuit from gas outlet 14.Because the inlet chamber of the first described valve pocket 11
101 are not provided with choke valve 16, do not have choke valve 16 to limit gas flow rate, and gas can be made quickly to be passed through gas circuit, the first valve pocket 11
With the second valve pocket 12 binary channel superposition, gas inflow velocity can be made faster.
Below only highly preferred embodiment of the present invention is described, but is not to be construed as limitations on claims.This
Invention is not limited only to above example, and all various changes made in the protection domain of independent claims of the present invention are all at this
In the protection domain of invention.
