In figure: 1 first valve pocket, 2 pressure springs, 3 drain taps, 4 first spools, 41 draining through holes, 5 oil-ins, 6 second valves
Chamber, 7 the 3rd spools, 8 internal control donsoles, 9 adjusting screw rods, 10 valve bodies, 11 oil-outs, 12 accumulators, 13 second spools, 14 outer control
Mouth, 15 the 3rd valve pockets.
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.
This utility model provides the air relief valve of a kind of two ore control as shown in Figure 1, including valve body 10, described valve body 10
Inside is provided with the first valve pocket 1, and described first side, valve pocket 1 top is provided with drain tap 3, and the side, middle part of described first valve pocket 1 sets
Having oil-out 11, described first side, valve pocket 1 bottom to be provided with oil-in 5, the bottom of described first valve pocket 1 is provided with accumulator 12,
Described oil-in 5 is communicated in accumulator 12, is provided with the first spool 4 in described first valve pocket 1, and described first spool 4 top connects
Having pressure spring 2, described pressure spring 2 one end connects the adjusting screw rod 9 through valve body 10 top, described first spool 4
Inside be provided with draining through hole 41, the centre position, bottom of described first valve pocket 1 is provided with the second valve pocket 6, described second valve pocket 6 end
The centre position in portion is provided with the 3rd valve pocket 15, and centre position bottom described first spool 4 connects the second spool 13, and described the
Centre position bottom two spools 13 connects has the 3rd spool 7, the bottom of described second valve pocket 6 to be communicated with external control donsole 14, institute
The bottom stating the 3rd valve pocket 15 is communicated with internal control donsole 8, between described first valve pocket 1 and the first spool 4, the second valve pocket 6 and
