Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.

This automatic drain valve of the utility model as shown in Figures 1 to 3, including valve chamber 1, electromagnetism column 2, valve seat 3, first Sealing connecting rod 4, the second sealing connecting rod 5, electromagnetic coil winding 6, hollow spring hole 7, resetting spring 8, osculum 9, seal 10, set Socket part 11, guide plate 12, sealing ring 13, the first sealing plate 14, resilient support part 15, the second sealing plate 16, electromagnetism column 17, through-hole 18 etc..First sealing plate 14 is manufactured using magnetic material, and electromagnetism column 17 is cylinder, and is fixed on the intermediate position of valve seat 3, electricity Magnetic coil winding 6 is arranged in the excircle of electromagnetism column, and the cylindrical design of electromagnetism column 17 can increase the winding face of electromagnetic coil Product increases electromagnetic force.

17 bottom of electromagnetism column is equipped with hollow spring hole 7, and 4 one end of the first sealing connecting rod is fixedly connected with the first sealing plate 14, separately One end is stretched into hollow spring hole 7 and is fixedly connected with one end of resilient support part 15, the other end of resilient support part 15 and reset Spring 8 is fixedly connected, resilient support part 15 and hollow 7 clearance fit of spring hole so that resilient support part 15 can be in hollow spring hole 7 It inside moves up and down, 8 other end of resetting spring is fixedly connected on the bottom surface that hollow spring hole 7 connects with valve seat 3, the second sealing connecting rod 5 One end is fixed on the same end face of the first sealing plate 14, and the first sealing bar 4 and the second sealing bar 5 with the first sealing connecting rod 4 The distance between be more than the sum of the radius of electromagnetism column 17 and osculum 9, the other end of the second sealing bar 5 and the second sealing plate 16 are consolidated Fixed connection, osculum 9 are located on valve seat 3, and osculum 9 is sealed end 91 towards one end of valve chamber 1, leads to one end outside valve chamber 1 For outlet side 92, the diameter of sealed end 91 is more than the diameter of outlet side 92, and the diameter of the second sealing plate 16 is less than sealed end 91 More than the diameter of outlet side 92, the diameter of the first sealing plate 14 is less than the diameter that seal 10 is more than valve chamber 1, which sets It sets so that the second sealing plate 16 and sealed end 91, the first sealing plate 14 can have enough sealing contact surfaces with seal 10, really It will not leak when protecting engine charge.

Guide plate 12 is fixed between 2 outer wall of madial wall and electromagnetism column of valve chamber 1, and guide plate 12 is equipped with through-hole 18, through-hole 18 diameter is more than the diameter of the second sealing connecting rod 5, the two clearance fit, and osculum 9, the sealing of second seal 16, second connect Bar 5, through-hole 18 all keep axis line to arrange so that discharging valve can be with even running when being opened and closed.

Electromagnetic coil winding 6 is electrically connected to power supply, after engine start, starts discharging valve through socket part 11 and engine Admission line connects, and power supply starts output current, and electromagnetic coil winding 6 generates electromagnetic force after entering electric current, in the suction of electromagnetic force Under attached effect, 4 compression reseting spring 8 of the first sealing connecting rod is pulled on using the first sealing plate 14 made of magnetic metal, in turn It is fitted on seal 10, at the same time, the second sealing bar 5 also pushes the second sealing plate 16 to be fitted in the close of discharge outlet 9 therewith On sealing end 91, when the design of double rod sealing makes engine work, the high pressure draught into air inlet pipe will not be flowed out out of valve body, The reduction of engine charge effect is avoided, the efficiency of combustion of engine is influenced.When the engine is not operating, power supply stops to electromagnetism Coil windings are powered, and electromagnetic coil winding 6 loses supply of electric power, and magnetic force disappears, under the elastic force effect of resetting spring 8, first Sealing plate 14 and the second sealing plate 16 all leave sealing station, and discharging valve is opened so that when engine does not work, air intake duct The steam of interior condensation is able to be expelled directly out by discharging valve.

According to further aspect of the application, the application also provides a kind of engine system as shown in Figure 4, the engine System includes above-mentioned automatic drain valve 112 and inlet manifold 111, exhaust manifold 113, cylinder body 114, valve mechanism cover 115, cylinder Lid 116, air cleaner 117 etc., using the automatic drain valve 112 in the engine system, when engine does not work power supply with Disconnection, discharging valve is reset to opening state, and the water condensed in inlet manifold 111 can be discharged from discharging valve 112, and engine opens After dynamic, power supply outputs current to discharging valve and is accordingly turned off under the action of electromagnetic force therewith, it is ensured that the air-flow in inlet manifold exists Engine work when will not be escaped from discharging valve, need not additionally increase other control units can realize discharging valve from Dynamic opening and closing, and do not generate interference to engine aspirating system.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Utility model spirit and principle within, made by any modification, equivalent replacement and improve etc., should be included in the utility model Protection domain within.
