(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing solenoid valve, the utility model provides a kind of conducting solenoid valve that is implemented in other routes under the cut-off state.
The technical scheme in the invention for solving the technical problem is: a kind of solenoid valve, comprise plastic packaging, and in the described plastic packaging coil rack is arranged, be wound with coil on the described coil rack, described coil is connected with inserted sheet;
Also comprise fixing quiet spool, described quiet spool is positioned at described coil rack, and described quiet spool has the air passageways from extraneous bubbling air of being used for that axially runs through, and there is outlet passageway in the place ahead of described quiet spool;
Also comprise a gas-entered passageway, the import UNICOM of the outlet of described gas-entered passageway and described air passageways and outlet passageway;
Between described outlet passageway and the described quiet spool movable valve plug is arranged, described movable valve plug is provided with caulking gum, and two of described caulking gum is aimed at the outlet of described air passageways and the import of outlet passageway respectively; Also have stage clip between described movable valve plug and the described quiet spool, a crown of described stage clip is on described movable valve plug, and the other end of described stage clip withstands on the described quiet spool.
Further, described outlet passageway is over against described air passageways.
Further, described coil rack has axial installation passage, and described quiet spool and described movable valve plug all are positioned at described installation passage; Described outlet passageway and described gas-entered passageway and described coil rack are integral, and described gas-entered passageway is by installation passage and the outlet of described air passageways and the import UNICOM of outlet passageway in the described coil rack.
Further, be provided with the support that a cross section takes the shape of the letter U in the described plastic packaging, described coil rack is located in the described support.
Further, the import of described air passageways also is provided with protective cover outward.
The utility model can use in the manifolding of automobile engine system, and wherein outlet passageway is connected with motor, and gas-entered passageway is connected with vacuum actor.Working principle of the present utility model is: when inserted sheet access failure power supply, because the effect of stage clip.Make the caulking gum on the movable valve plug hold out against in the import of outlet passageway, this moment outlet passageway and gas-entered passageway UNICOM not, gas-entered passageway and air passageways UNICOM, ambient air flow to gas-entered passageway by air passageways and then flow in the vacuum actor; When inserted sheet is connected power supply, because producing the axial magnetic field force, coil make movable valve plug deviate from the outlet passageway motion, outlet by caulking gum sealing air passage, this moment gas-entered passageway and outlet passageway UNICOM, under suction function, make the air in the vacuum actor flow to outlet passageway, flow in the motor through gas-entered passageway.
The beneficial effects of the utility model are: be implemented in the conducting of other routes under the cut-off state, be particularly useful in the manifolding of automobile engine system.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
A kind of solenoid valve comprises plastic packaging 1, is provided with the support 2 that a cross section takes the shape of the letter U in the plastic packaging 1, is provided with coil rack 3 in this support 2, is wound with coil 4 on the described coil rack 3, and described coil 4 is connected with inserted sheet 5.
Coil rack 3 has axial installation passage 6, and these axial installation passage 6 internal fixation have a quiet spool 7, and described quiet spool 7 has the air passageways 8 from extraneous bubbling air of being used for that axially runs through, and the import of described air passageways 8 also is provided with protective cover outward.There is the outlet passageway 9 over against air passageways 8 in the place ahead of described quiet spool 7, and this outlet passageway 9 is integral with described coil rack 3.
Also comprise one with coil rack 3 all-in-one-piece gas-entered passageways 10, described gas-entered passageway 10 and the outlet of described air passageways 8 and the import UNICOM of outlet passageway 9, gas-entered passageway 10 is by the installation passage in the described coil rack 6 and the outlet of described air passageways 8 and the import UNICOM of outlet passageway 9 in the present embodiment.
The movable valve plug 11 that the installation passage 6 that is positioned at coil rack is arranged between described outlet passageway 9 and the described quiet spool 7, described movable valve plug 11 is provided with caulking gum 12, and two of described caulking gum 12 is aimed at the outlet of described air passageways 6 and the import of outlet passageway 9 respectively; Also have stage clip 13 between described movable valve plug 11 and the described quiet spool 7, a crown of described stage clip 13 is on described movable valve plug 11, and the other end of described stage clip 13 withstands on the described quiet spool 7.
