Description
Technical field
The present invention relates to a kind of hydraulic and automatic flow control valve.
Background technique
The speed of the present hudraulic lift and the lifting of hydraulic elevating platform controls by the modulating valve of hydraulic flow mainly that the hydraulic pressure installation inner stream flow realizes; Existing flow control valve mainly comprises valve body and screw rod, on valve body, be provided with the screw rod chamber, filler opening and oil outlet, screw rod is placed in the screw rod chamber, the screw rod chamber communicates with filler opening and oil outlet, control the position of screw rod in the screw rod chamber according to the control signal of peripheral control unit during work, and the size of screw rod control oil outlet or filler opening and screw rod chamber intercommunicating pore, thereby realize the automatic control of regulating and controlling valve flow, but this regulating valve flow is regulated unstable, the pressure regulation difficulty can appear under the hydraulic pressure condition with higher, oil when hydraulic pressure is big in the piston cavity can produce very big resistance to piston, can cause the piston jacking very difficult, when pressure is very big, also the screw rod stuck phenomenon can occur.
Summary of the invention
The object of the present invention is to provide a kind of hydraulic and automatic flow control valve, it is steady to have Flow-rate adjustment, and it is little to regulate resistance, the high characteristics of stuck phenomenon and functional reliability can not occur.
For achieving the above object, by the following technical solutions:
A kind of hydraulic and automatic flow control valve comprises valve body and piston, is provided with piston cavity, filler opening and oil outlet on valve body, and filler opening and oil outlet all communicate with piston cavity, and piston is placed in the piston cavity; It is characterized in that: a gear cavity also is set on the valve body, and gear cavity and piston cavity are communicated with, and are equipped with adjusting gear in the gear cavity; Described piston is provided with oil inlet hole and oil outlet, the shape of described oil inlet hole and oil outlet is triangle, its position is corresponding with filler opening and oil outlet on the valve body respectively, and oil inlet hole and oil outlet communicate at internal piston, also are provided with the groove that is meshed with adjusting gear at piston face.
Between oil inlet hole and oil outlet, be provided with lubrication groove on the described piston.
On gear cavity one side of valve body, also be provided with regulating block, be provided with horizontal worm gear chamber and vertical worm gear chamber in the regulating block, in vertical worm gear chamber, be equipped with worm screw.
The end that the gear shaft of described adjusting gear is exposed to the gear cavity outside is provided with wrom tooth, and wrom tooth is placed in the horizontal worm gear chamber and is meshed with worm screw.
The end of described piston is provided with anti-jamming device.
Described anti-jamming device is made up of double speed oil cylinder, connecting rod, spring and buffer cell.
The present invention controls the size of intercommunicating pore between filler opening and fuel-displaced oral pore and the internal piston passage by moving of piston position, thereby realize control to the modulating valve inner stream flow, because of hydraulic oil flows at internal piston, therefore when work not pipe pressure have much, all can not produce resistance to the adjusting of piston, lubrication groove is set on piston simultaneously, can guarantees better that when work piston moves in piston.The present invention also is provided with anti-jamming device on the end of piston in addition, can prevent that piston from moving because excessive velocities or pressure produce stuck phenomenon when big; The present invention also comes the control piston position by worm gear and gear interlock, can make that the instantaneity when piston moves is better.Newly to have Flow-rate adjustment steady in this practicality thus, and it is little to regulate resistance, the high characteristics of stuck phenomenon and functional reliability can not occur.
