The scope of the utility model protection.
Referring to Fig. 1, a kind of single axle Hydraulic guide control valve, including valve body 1, the core assembly 2 in valve body 1,
The Handleset 3 being movably connected on valve body 1, the part of Handleset 3 are stretched into inside valve body 1, and rotational handle component promotes valve with 3
Core assembly 2, Handleset 3 is interior to be provided with friction plate assembly 31, and friction plate assembly 31 is determined it after the rotation of Handleset 3
Position.
In addition, friction plate assembly 31 includes tensioner nut 311, it is provided with tensioner nut 311 and is used to determine friction plate assembly
The stud 312 of frictional force, the side of tensioner nut 311 are provided with the first wear plate 313, and opposite side is provided with disc spring 314, disc spring 314
Side be provided with the second wear plate 315.Friction plate assembly 311 is by the second wear plate 313, pad, disc spring 314, pad, risen
Enter nut 311, the wear plate 313 of interior hexagonal double-ended bolt 312 and first assembles in order, the size of frictional force is by interior hexagonal double-ended bolt
312 screw in rise into nut 311 depth decision；Torque caused by frictional force is greater than caused when ram piston 26 works
Torque, so that when control-rod deflects, any angle specified can be fixed on.Interior hexagonal double-ended bolt 312 is screwed in tensioner nut
In 311, and disc spring can be extruded, the interior screw-in of hexagonal double-ended bolt 312 tensioner nut 311 is deeper, will extrude and become caused by disc spring 314
Shape is bigger, and the first wear plate 313 and the second wear plate 315 are squeezed and produce micro-deformation, make its upper and lower ends face and handle set
33 are in contact, and now will produce frictional force, frictional force between the first wear plate 313 and the second wear plate 315 and handle set 33
Caused torque is greater than caused torque when ram piston 26 works, so that when control-rod deflects, can fix in office
The angle what is specified, deformation force are just consequently exerted at the pressure of wear plate, and it is exactly caused that this pressure, which is multiplied by corresponding coefficient of friction,
Frictional force.
In addition, Handleset 3 includes handlebar 32 and handle set 33, handlebar 32 is connected on handle set 33, handle set
33 are hinged on valve body, and for friction plate assembly 31 inside handle set 33, handle set 33 and the first wear plate 313 and second are wear-resisting
Piece 314 be in contact produce frictional force Handleset 3 is positioned.
In addition, handle set 33 is in contact with core assembly 2, the rotational band fixed handle seat 33 of handlebar 32 is to promote core assembly
2。
In addition, core assembly 2 includes valve element 21, pressure spring 22 and back-moving spring 23 are arranged with valve element 21, on valve element 2
End is provided with the spring base 24 for being used for fixing pressure spring 22 and back-moving spring 23, and the upper end of spring base 24 is provided with tip-lever support 25, push rod
The inside of seat 25 is provided with ram piston 26, and ram piston 26 is in contact with handle set 25.The bore depth of ram piston 26 decides

In addition, valve body 1 is provided with oil inlet P, oil-out T, first guide's hydraulic fluid port 4 and second guide's hydraulic fluid port 5.
The utility model single axle Hydraulic guide control valve concrete operating principle is as follows：When Handleset 3 enters horizontal deflection,
Ram piston stress moves down, and by compression reseting spring 23 and promotes pressure spring 22, and pressure spring 22 starts to move down,
And valve element 21 is promoted, valve element 21 is cut off the connection between relevant work hydraulic fluid port and oil-out T.Meanwhile this work has mouth to pass through
Duct inside valve element 21 is connected with oil inlet P.When power caused by the power of pressure spring 24 and the oil liquid pressure of this actuator port
When equal, now valve element 21 is in poised state, and Hydraulic guide control is started working.Pressure spring 24 and the phase interaction of valve element 21
With so that the hydraulic coupling of actuator port and the stroke of ram piston 26 are linear, so as to the deflection angle with Handleset
Into certain ratio.And by adjusting the different stroke-limits of ram piston 26, different Hydraulic guide controls can be obtained
Curve, to meet different matching demands.Because torque caused by friction plate assembly 31 is more than produced when ram piston works
Torque so that when handle deflects, can be fixed by friction plate assembly makes handlebar in any angle specified, when hand pine
When opening, handlebar can be fixed on corresponding position, and control is stable, mitigate operation fatigue.
