Description
Technical field
It the utility model is related to a kind of guiding valve instruction device with displacement equations and position instruction.
Background technology
Guiding valve is to utilize valve element（Plunger, flap）Slided on sealing surface, change fluid inlet and outlet channel position to control
The flow divider of fluid flow direction, because its simple in construction, easy to operate, reliable operation is now usually used in various hydraulic means.Current guiding valve
There is an indicating arm moved together with valve element, but because of valve element displacement often very little, only several millimeters, without bright on indicating arm
True scale and displacement is consistent with valve element displacement, on the one hand can not precisely judge valve element according to the distance of indicating arm movement
Position, when there is valve element hair fastener or movement is not in place, by eye-observation it is difficult to realize；Another aspect indicating arm displacement
It is small that enough stroke triggering external sensors can not be provided, spool position status signal is fed back into control system and reaches closed loop control
Purpose processed.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of with displacement equations and the guiding valve of position instruction instruction dress
Put, solve the problems, such as that spool position is small without accurate instruction and the instruction throw of lever.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of band displacement equations and position instruction
Guiding valve instruction device, including one end is connected to the base on guiding valve valve body and the indicating mechanism on base, the finger
Show that mechanism includes housing, wedge and indicating arm are provided with housing, indicating arm lower end is pressed on wedge inclined-plane, and wedge leads to
A pull bar is crossed to be connected with valve core of the spool valve.
Indicating arm lower surface is inclined-plane, offers a groove on the inclined-plane, more balls be arranged in order be arranged on it is recessed
In groove, each ball is pressed against on wedge inclined-plane on indicating arm lower surface.
Graduation mark is provided with indicating arm.
The wedge includes block and swash plate, and swash plate one end is hinged on block, and the swash plate other end passes through spring and block
Body connects, and jackscrew is provided with swash plate, jackscrew one end is resisted against on block, and indicating arm lower end is pressed on swash plate.
The beneficial effects of the utility model are：Indicating arm can accurately indicate valve core of the spool valve position, judge for guiding valve state, event
Barrier diagnosis provides condition directly perceived, and the displacement of amplification drives external sensor to carry out signal feedback, strengthens HYDRAULIC CONTROL SYSTEM enough
Stability.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings：
Fig. 1 is cross-sectional view of the present utility model,
Fig. 2 is the cross-sectional view of the utility model when in use,
Fig. 3 is cross-sectional view of the utility model on indicating arm.
In figure：Guiding valve 1, base 2, housing 3, wedge 4, indicating arm 5, pull bar 6, valve body 11, valve element 12, block 41,

Embodiment
As shown in Fig. 1 to 3, a kind of guiding valve instruction device with displacement equations and position instruction, including one end are connected to cunning
Base 2 on valve body 11 and the indicating mechanism on base 2, the indicating mechanism include housing 3, set in housing 3
There are wedge 4 and indicating arm 5, the lower end of indicating arm 5 is pressed on the inclined-plane of wedge 4, and wedge 4 passes through a pull bar 6 and guiding valve
Valve element 12 connects.
At work, valve element 12 moves horizontally drives wedge 4 to move horizontally to the utility model, and wedge 4 is by valve element 12
Horizontal displacement is converted to the vertical displacement of indicating arm 5, according to trigonometric function theorem, the angle of the inclined-plane of wedge 4 and horizontal direction
Displacement equations multiple is determined, and then solves the problems, such as that the position of valve element 12 is small without accurate instruction and the stroke of indicating arm 5, is the shape of guiding valve 1
State judges, fault diagnosis provides condition directly perceived, and the displacement of amplification drives external sensor to carry out signal feedback enough, strengthens hydraulic pressure
The stability of system control.
The lower surface of indicating arm 5 is inclined-plane, and a groove 51 is offered on the inclined-plane, and more balls 52 are arranged in order setting
In groove 51, each ball 52 is pressed against on the inclined-plane of wedge 4 on the lower surface of indicating arm 5.Ball 52 can reduce friction, keep away
Exempt from bite when wedge 4 promotes indicating arm 5.
Graduation mark 53 is provided with indicating arm 5.Graduation mark 53 can be in order to reading the displacement of valve element 12.
The wedge 4 includes block 41 and swash plate 42, and the one end of swash plate 42 is hinged on block 41, and the other end of swash plate 42 leads to
Cross spring 44 to be connected with block 41, jackscrew 43 is installed on swash plate 42, the one end of jackscrew 43 is resisted against on block 41, indicating arm 5
Lower end is pressed on swash plate 42.Angle between the surface of swash plate 42 and horizontal plane can be adjusted by rotating jackscrew 43, with to displacement
Multiplication factor be finely adjusted.
