Feature.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: shown in Fig. 1, a kind of oil described in the utility model
Double steering valve is pumped, its main by valve body and thereon oilhole, positioning stud, locking-valve or steel ball forms, symmetrical on the valve body 5
Ground is equipped with lower-left positioning stud 1 and bottom right positioning stud 18, upper left positioning stud 4 and upper right positioning stud 15, and lower-left
Positioning stud 1 is connected to bottom right positioning stud 18 by lower oil duct 19, and upper left positioning stud 4 passes through upper with upper right positioning stud 15
Oil duct 14 is connected to, and is mounted with work locking-valve 6 in above-mentioned upper oil duct 14, is mounted with oil suction locking-valve 21 in lower oil duct 19；The valve
The top of body 5 is equipped with working oil path adapter tube 10 by the built-in fuel-displaced nut 9 of check valve 11 and spring 12；The working oil
The two sides of road adapter tube 10 are respectively arranged with left oil suction duct 7 and right oil suction duct 13, the left oil suction duct 7 and right oil suction duct
13 upper end is each configured with bored plug 8, and lower end extends downwardly respectively, and is sequentially communicated oil duct 14 and lower oil duct respectively
19, the lower part of the valve body 5 is provided with the gear-box oil sump interface 20 for being connected to lower oil duct 19.
As shown in the figure, the left guide of oil duct 14 and lower oil duct 19 on vertical connection is respectively arranged with inside the valve body 5
Oil suction duct 2 and right guide's oil suction duct 17；And in the left and right sides of valve body 5, be located at lower-left positioning stud 1 and upper left positioning stud
4, difference parallel with upper oil duct 14 and lower oil duct 19 is respectively arranged between bottom right positioning stud 18 and upper right positioning stud 15
Each communicate with left guide's oil suction duct 2 and left oil suction duct 7, right guide's oil suction duct 17 and right oil suction duct 13 connects an oil pump left side
Flowline 3 and connect the right flowline 16 of oil pump.
When oil pump rotates forward, the hydraulic fluid port for connecing the left flowline 3 of oil pump is oil suction state, and left guide's oil suction duct 2 is at this time
Negative pressure state；Oil suction locking-valve 21 is mobile toward lower-left positioning stud 1, until encountering at lower-left positioning stud 1, left oil suction duct 7
Lead to the oil circuit for connecing gear-box oil sump interface 20, form oil suction, while because oil suction state is negative pressure, work locking-valve 6 is fixed toward upper left
