Specific embodiment
Now in conjunction with attached drawing, the utility model is described in further detail.
As shown in Figs 1-4, a kind of high frequency sound big flow switch electromagnetic valve, includes valve pocket 1, and 1 upper end of valve pocket is equipped with electricity
Magnet 2, lower end are equipped with control port 3, channel 4 are equipped in valve pocket 1, spool 5,5 lower part of spool and valve pocket 1 are equipped in channel 4
There is oil circuit 6, for 1 side wall of valve pocket equipped with connection oil circuit 6 for oil supply port 7, oil circuit 6 passes through openable sealing 8 between inner wall
It is connected to control port 3, the reset spring 9 for up withstanding spool 5 is installed at control port 3, between valve pocket 1 and electromagnet 2
Equipped with press oil port 10 is unloaded, the electromagnet 2 includes dynamic iron core 11 and the movable chamber 12 for the up and down motion of dynamic iron core 11, activity
Press oil port 10 is unloaded in the lower end connection of chamber 12, and spool 5 connects dynamic iron core 11 by connecting rod 13, and 1 upper end of valve pocket is equipped with and wears for connecting rod 13
The opening 14 crossed, the lower surface of dynamic iron core 11 can cover opening 14 completely, be equipped with access 15, access 15 inside the spool 5
Lower end is connected to control port 3,15 upper end of access connection opening 14.
First tapered face 16 of the sealing 8 by being set on 1 inner wall of valve pocket and the second tapered face 17 on spool 5 are bonded
It constitutes.
Access 15 passes through radial oil-through-hole 18 and is connected to opening 14 with axial oil-through-hole 19.
The surface of dynamic iron core 11 has axial exhaust slot 20.
Reset spring 9 is fixed on control port 3 by locating cover 21, locating cover 21 and valve pocket 1 using interference riveting or
Thread forms connection.
When electromagnet 2 does not turn on driving power, dynamic iron core 11 is in release conditions, precompressed of the spool 5 by reset spring 9
The effect of power forms sealing so that the second tapered face 17 on spool 5 is bonded with the first tapered face 16 on 1 inner wall of valve pocket
8, sealing function is played, the channel for oil supply port 7 and control port 3 is blocked.The precompression of reset spring 9 passes through spool 5 simultaneously
