Abstract
The utility model discloses an electromagnetic throttled directional valve, and belongs to the technical field of hydraulics. The electromagnetic throttled directional valve comprises an ultrasonic range sensor, a controller, a valve body, an oil chamber, a threaded sleeve, a stepping motor, a screw rod, oil holes and sliding valves, wherein the ultrasonic range sensor and the stepping motor are mounted at two ends of the valve body respectively; the controller is mounted at the upper part of the valve body; four oil holes are formed in the lower part of the valve body; the sliding valves are arranged in the valve body; the oil chamber is formed between the sliding valves and the valve body; the controller is connected with the ultrasonic range sensor and the stepping motor through conducting wires; the threaded sleeve is arranged at one end of the valve body; and the screw rod is mounted in the threaded sleeve and connected with the stepping motor. The electromagnetic throttled directional valve has a direction changing function and a throttling function simultaneously and is accurately controlled by the control system, the electrification is realized, and the use efficiency is high.
Description
Technical field
The utility model relates to electromagnetism throttled directional valve, belongs to hydraulics field.
Background technique
Along with the development of modern science and technology, the utilization of hydraulics is also more and more extensive, and throttle valve and the selector valve on hydraulic pressure, used at present all separate substantially, have so just reduced the execution efficiency of hydraulic system, are urgent problems.
Summary of the invention
The purpose of this utility model is to provide electromagnetism throttled directional valve.
Problem to be solved in the utility model is that existing throttle valve and selector valve separate the deficiency that operation efficiency is low.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
Electromagnetism throttled directional valve, comprise ultrasonic distance sensor, controller, valve body, oil pocket, swivel nut, stepper motor, screw rod, oilhole and guiding valve, described valve body two ends are separately installed with ultrasonic distance sensor, stepper motor, valve body top is provided with controller, valve body lower portion is provided with four oilholes, in valve body, be provided with guiding valve, it between guiding valve and valve body, is oil pocket, controller is connected with ultrasonic distance sensor, stepper motor by wire, valve body one end is provided with swivel nut, screw rod is installed in swivel nut, and screw rod is connected with stepper motor.
Described controller is single-chip computer control system.
Described swivel nut is rectangular structure, is provided with internal thread.
Advantage of the present utility model: this device commutation function and throttling function possess simultaneously, and accurately control by control system, have realized motorized, and utilization efficiency is high, should have the market space widely.
Accompanying drawing explanation
Fig. 1 is the stereogram of the utility model electromagnetism throttled directional valve;
In figure: 1, ultrasonic distance sensor 2, controller 3, valve body 4, oil pocket 5, swivel nut 6, stepper motor 7, screw rod 8, oilhole 9, guiding valve.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Electromagnetism throttled directional valve, comprise ultrasonic distance sensor 1, controller 2, valve body 3, oil pocket 4, swivel nut 5, stepper motor 6, screw rod 7, oilhole 8 and guiding valve 9, described valve body 3 two ends are separately installed with ultrasonic distance sensor 1, stepper motor 6, valve body 3 tops are provided with controller 2, valve body 3 bottoms are provided with four oilholes 8, for realizing the oily commutation of turnover, in valve body 3, be provided with guiding valve 9, between guiding valve 9 and valve body 3, it is oil pocket 4, controller 2 is by wire and ultrasonic distance sensor 1, stepper motor 6 is connected, and control feedback and the action of its signal, valve body 3 one end are provided with swivel nut 5, screw rod 7 is installed in swivel nut 5, screw rod 7 is connected with stepper motor 6, the rotation of drive screw 7.
Described controller 2 is single-chip computer control system, has signal output accurately.
Described swivel nut 5 is rectangular structure, is provided with internal thread, by the cooperation with screw rod 7, is realized and being moved around.
Using method: this valve body 3 is linked in hydraulic system, when needs commutate, controller 2 sends pulse signal control step motor 6 and rotates certain number of turns, under the cooperation of screw rod 7, make guiding valve 9 move distance accurately and realize commutation, when needs throttling, controller 2 sends pulse signal control step motor 6 and rotates the less number of turns, make the partially enclosed oilhole 8 of guiding valve 9, thereby realize throttling, whether ultrasonic distance sensor 1 is accurate for feeding back displacement distance, plays the effect of a supervision.
