Solving the technical solution of above-mentioned technical problem is：A kind of valve member of big flow electromagnetic type injector, including Spool, seal, valve seat, the seal are sealed plunger, and coaxial spool mounting hole and center are equipped in sealed plunger The bottom terminal ends of hole, the spool mounting hole and spool connect, and the bottom end end face of sealed plunger is plane；The valve seat is set There is the matched sealing plane in bottom end end face with sealed plunger, the sealing plane is corresponding with the centre bore of sealed plunger Position is equipped with turbulent chamber, and spray-hole is equipped with around turbulent chamber.
The present invention further technical solution be：The valve seat includes valve seat A and valve seat B, and the top end face of valve seat A is The sealing plane, valve seat A are connect with the lower end of valve seat B, and the upper end of valve seat B is connect with main shaft.
The present invention further technical solution be：Between the bottom end end face and the sealing plane of valve seat A of sealed plunger Gap L is 0.05~0.2mm.
The present invention further technical solution be：Between between the bottom end end face and the sealing plane of valve seat A of sealed plunger The cross-sectional area of gap is 1.5~2.5mm2。
Due to using the above structure, the valve member and prior art phase of the big flow electromagnetic valve type injector of the present invention Than having the advantages that：
1. the metering range of available big flow
The present invention includes spool, seal, valve seat, and the seal is sealed plunger, and coaxial valve is equipped in sealed plunger The bottom terminal ends of core mounting hole and centre bore, the spool mounting hole and spool connect, and the bottom end end face of sealed plunger is flat Face；The valve seat is equipped with the matched sealing plane in bottom end end face with sealed plunger, the sealing plane with sealed plunger The corresponding position of centre bore be equipped with turbulent chamber, and spray-hole is equipped with around turbulent chamber.Since the present invention seals ball Structure is changed to plane sealing structure, is designed under plane sealing structure under identical back-pressure sealing area structure and gap, can be with The via area for obtaining 2.5 times of ball sealing structures, to can get the metering range of big flow.
2. dependable performance
Since ball sealing structure is changed to plane sealing structure by the present invention, sealing performance not only can be improved, but also sealing element Processing technology is greatly improved, and can be processed using conventional turning, grinding, heat treatment and fine grinding, high in machining efficiency, close Sealing property is reliable and stable.
3. simple in structure
Relatively simple for structure, at low cost, the use easy to spread of the present invention.
In the following, special to the technology of the valve member of the big flow electromagnetic valve type injector of the present invention in conjunction with the accompanying drawings and embodiments Sign is further described.
