Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-2, a kind of technical scheme of this utility model offer: a kind of hydraulic pressure self-filtering type overflow valve, including valve
Body 1, described valve body 1 one end is provided with oil-in 2, and described oil-in 2 is internal is provided with permanent magnet filtration group 3, and described permanent magnet filters
Organize 3 surfaces and have filtering holes 31, and filtering holes 31 is through permanent magnet filtration group 3, is provided with magnet strip 32 in described filtering holes 31,
Described oil-in 2 side is communicated with the first valve pocket 5, and described first valve pocket 5 interior side is provided with compression spring 4, described first valve
Side, chamber 5 is provided with the second valve pocket 7, is provided with valve pocket hole 6 between described first valve pocket 5 and the second valve pocket 7, and described valve body 1 side sets
Having adjusting handle 11, described adjusting handle 11 is through valve body 1 and extends in the second valve pocket 7, described adjusting handle 11 side
Being provided with sealing block 10, described sealing block 10 one end connects pressure spring 13, and described pressure spring 13 one end connects spool 8,
Described second valve pocket 7 side lower surface is provided with connector 12, is communicated with oil-out 14, described second valve on the downside of described connector 12
Upper surface side, chamber 7 is provided with overflow pipe 9, and overflow pipe 9 is arranged on the upside of pressure spring 13, and described overflow pipe 9 other end connects
