Compare to determine in state is turned on and off, so as to realize that the double oil circuits of control unidirectionally lead to the function of oil.It is bullet to adjust spring force
The mode of spring decrement includes：Screw-in length between adjust pad thickness, adjustment valve base thickness, adjustment valve base and valve body,
Adjust unidirectional valve base thickness of coating, processing is reserved.Pressure measuring tie-in is connected with oiler, for detecting oiler pressure.
After two check valve independent parallels in the utility model are worked, and valve group is completed, one-way valve seat exposes
Valve plate, it is readily disassembled, assembles, is conveniently adjusted pad, adjustment base screw-in length.It is pre- by processing using this technical scheme
Stay, adjust the means such as valve seat screw-in length, spacer thickness and valve base thickness of coating, adjust the unlatching pressure of each check valve
Power.So as to control two oil circuits to be opened and closed by two Opening pressure values, the relatively accurate control of each oil circuit flow is realized.

Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
As shown in figure 1, check valve I 11, check valve II 12 are located at the both sides of valve plate 21 respectively, straight-through oil-out 14 is located at valve
Among plate front, straight-through oil-out 14 connects sebific duct and leads to cooler, and oil-out II 16 is located at valve plate front close to check valve II
12 sides.
It is connected as shown in Fig. 2 oiler 13 is located at centre, pressure measuring tie-in 22 above valve plate 21 with oiler 13, uses
In detection oiler pressure value.
As shown in figure 3, oil-out I 15 is located at below valve plate close to the side of check valve I 11, operating space is enough herein, just
In connection.
As shown in Figure 4, Figure 5, oiler 13 directly connects with straight-through oil-out 14, and check valve I 11, check valve II 12 enter
Mouth directly connects with oiler 13, and oil-out I 15 directly connects with the outlet of check valve I 11, oil-out II 16 and check valve
II 12 outlet directly connects.
Oiler 13, straight-through oil-out 14, II 16 3 interface present positions of oil-out and gearbox lubrication system temperature control
Group corresponding interface present position is basically identical, and it is convenient to replace, and saves cost.
The check valve I 11, the check valve II 12 use angle check valve, including unidirectional valve base 23, unidirectional
Valve body 24, inner elements of check valve 25, spring 26.The one end of spring 26 is pressed against in unidirectional valve base 23, and the other end is pressed against check valve
Valve element 25；Valve element 25 is in sealing contact using boring with check valve valve body 24；Unidirectional valve base 23 passes through screw thread with check valve valve body 24
