Specific embodiment
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 this utility model a part of embodiment, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Fig. 1-4 are referred to, this utility model provides a kind of technical scheme：The hydraulic control that a kind of hydraulic rockshaft is used
Valve, including valve body 1,1 outer wall of the valve body are provided with plug 2, and 1 one end of the valve body is provided with pin 3, and connection is rotated on the pin 3
There is linkage board 4, side is provided with check valve valve body 5 in the valve body 1, inner elements of check valve 6, institute is provided with the check valve valve body 5
State 6 one end of inner elements of check valve and be provided with the first spring 7, described first spring, 7 one end is provided with stifled 9, it is described stifled between 9 and 1 inwall of valve body
Back-up ring 8 is provided with, inner valve body 12 in the valve body 1, at the top of opposite side, is provided with, inner spool 11 in the inner valve body 12, is provided with, it is described interior
11 right-hand member of valve element is provided with second spring 10, and 11 left end of the inner spool is provided with stud 13, is threaded with spiral shell on the stud 13
Female 14,12 bottom of the inner valve body is provided with change-over valve core 18, and 18 one end of the change-over valve core slidably connects spring base 16,
16 right-hand member of the spring base is provided with the jump ring 15 being connected on change-over valve core 18, and 16 left end of the spring base is provided with the 3rd spring
17,18 left end of the change-over valve core is provided with the 4th spring 19, and 19 left end of the 4th spring is provided with piston 20, the piston 20
Left end is provided with bolt 21.
O-ring is equipped between 1 inwall of the check valve valve body 5 and inner valve body 12 and valve body.The number of the plug 2 is two
It is individual.The bolt 21 is M8 bolts.
Specifically, during use, the movement of change-over valve core 18, control valve control three kinds of states of hydraulic cylinder rise, it is neutral and
Decline.Change-over valve core 18 and inner spool 11 are linked together by linkage board 4, it is possible to achieve hydraulic cylinder neutral position hydraulic oil
Cut-off, keeps its neutral position.Its raising and lowering can also be realized.Change-over valve core 18, can above with connection control mouth
So that the direction of motion of inner spool 11, the also connecting spring of change-over valve core 18, by spring and external force phase are controlled by external strength
The result of interaction determines the position of valve element.Inner spool 11 has two positions, corresponds to hydraulic cylinder respectively and rises, neutral and lower decrease
Put.It passes through linkage board 4 and change-over valve core 18 links together, while action, controls the Different Exercise Mode of hydraulic cylinder.It is interior
11 one end of valve element is also connected with spring, and the collective effect of spring and external strength determines its position.6 one end of inner elements of check valve
Spring is connected with, when there is positive hydraulic pressure strength, spring-compressed, inner elements of check valve 6 and check valve valve body 5 form space, hydraulic pressure
Oil flows into hydraulic cylinder by valve body.When there is reverse hydraulic pressure strength, inner elements of check valve 6 and check valve valve body 5 are by hydraulic pressure strength pressure
Together, no gap, hydraulic oil cannot pass through.When hydraulic cylinder to be made rises, it is added on change-over valve core 8 by external force,
Compression is connected in the 3rd spring 17 on change-over valve core 18, by linkage board 4 so that inner spool 11 is also at lifting position, liquid
Force feed makes hydraulic cylinder be in propradation by change-over valve core 18 and check valve valve body 5 into hydraulic cylinder.If when hydraulic pressure
In cylinder immediately, change-over valve core 18 is stretched out by external force, no longer to hydraulic pressure oil supply cylinder, inner spool 11 is in unidirectional cutoff shape
State, hydraulic oil can not be flowed out from hydraulic cylinder, and hydraulic cylinder piston rod is in neutral condition.When hydraulic cylinder will be made to decline state, lead to
Cross external force and redraw change-over valve core 18, not to hydraulic pressure oil supply cylinder, inner spool 11 is in open mode, and hydraulic oil can be from hydraulic pressure
Cylinder flows back to fuel tank by inner spool 11, and in hydraulic cylinder, hydraulic oil tails off, and piston 20 declines.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
Be appreciated that these embodiments can be carried out various changes in the case of without departing from principle of the present utility model and spirit, repair
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
