Abstract
Hydraulic pressure rotary power power generation facility's hydraulic pressure fuel tap structure includes and locates the fuel tap on the hydraulic pressure cylinder body, the fuel tap passes through the hydraulic oil return circuit and is connected with the hydraulic pressure station, the fuel tap includes case and disk seat, and the disk seat includes inlet port, oil outlet, inserts the end, and the looks remote site that inserts the end is a closing cap, and the closing cap inboard is equipped with return spring, and the case is equipped with outer end, insert head, first annular, second annular, in the case inserted the disk seat, when first annular and inlet port corresponded constitution oil feed passageway, the passageway that produces oil was closed, corresponding at second annular and oil outlet and constituting when producing oil the passageway, the oil feed passageway is closed, the case action is linked with the bent axle by cam control, cam. Filling valve and vent valve structure as an organic whole have been realized to this device, have simplified the structure, have solved the solenoid valve time -lag action and have resulted in the poor problem of harmony between the hydraulic pressure generator multi -cylinder different bent axles physically.
Description
Technical field
The utility model relates to a kind of hydraulic oil valve arrangement, especially a kind of hydraulic oil valve arrangement for hydraulic rotating dynamic power device.
Background technique
Hydraulicdriven basic principle: hydraulic system utilizes oil hydraulic pump that the mechanical energy of prime mover is converted to the pressure energy of liquid, transferring energy is carried out by the change of fluid pressure energy, through the transmission of various control valve and pipeline, by means of hydraulic actuator (oil hydraulic cylinder or motor), fluid pressure can be converted to mechanical energy, thus drive operation mechanism, realize straight reciprocating motion and rotation motion.Liquid is wherein called working medium, is generally mineral oil, and the transmission component such as belt, chain and gear in its effect and mechanical transmission is similar.Hydraulic transmission has many outstanding advantages, and therefore its application widely.Electric energy uses widely at present, very clean a kind of energy.Number disclose a kind of hydraulic rotating dynamic power device for the Chinese patent of CN203702451U, the rotating mechanical energy of low speed, super large moment of torsion is provided by hydraulic energy, and adopt multi-cylinder relay-type bent axle and the bent Abduction of overlength work, thus export enough mechanical energy, to ensure to export enough electric energy.Find in application process, fuel tap on intrinsic hydraulic cylinder adopts electromagnetic valve structure, and inaccurate coordination between the different bent axles that the time-lag action of solenoid valve causes hydraulic generator multi-cylinder, affects the normal operation of complete machine.
Summary of the invention
The utility model provides a kind of hydraulic oil valve arrangement for hydraulic rotating dynamic power device.
The utility model adopts following technological scheme, comprise the fuel tap be located on hydraulic cylinder, described fuel tap is connected with hydraulic station by hydraulic oil circuit, it is characterized in that: described fuel tap comprises spool and valve seat, spool is round column structure, and valve seat is the cylindrical sleeve of mating with spool; Valve seat comprises oil inlet hole, oil outlet, insertion end, and the opposite end of insertion end is a closing cap, is provided with return spring inside closing cap, and spool is provided with external end head, insert head, the first annular groove, the second annular groove; Spool inserts in valve seat, the first annular groove is corresponding with oil inlet hole form oil inlet passage time, oil discharge passage closedown; The second annular groove is corresponding with oil outlet form oil discharge passage time, oil inlet passage close; The action of spool is by the cam production being located at external end head, and described cam and bent axle are connected.
Its principle is: the insert head of spool inserts in valve seat, insert head ends contact return spring, the external end head of spool is subject to the effect of cam and return spring, to-and-fro motion in valve seat, oil discharge passage and oil inlet passage shift to install, the first annular groove is corresponding with oil inlet hole form oil inlet passage time, oil discharge passage close; The second annular groove is corresponding with oil outlet form oil discharge passage time, oil inlet passage close.This device achieves oiling valve and draining valve is structure as a whole.
Advantage of the present utility model: this device achieves oiling valve and draining valve is structure as a whole, simplifies the structure, and effectively prevent the problem of inaccurate coordination between different bent axles that solenoid valve causes hydraulic generator multi-cylinder due to time-lag action.
