Description
Technical field
The utility model relates to a kind of hydraulic actuator, is the liquid integrated single-acting executor of a kind of novel electromechanical specifically.
Background technique
The normally pressured contracting spring of traditional single-acting executor, cluster spring are realized the homing action to final controlling element, and for example: single-action pneumatic executor need to provide independent source of the gas as power, and control accuracy is lower, less stable.When needs output high-torque, this moment, traditional single-acting executor can't meet the demands, traditional single-acting executor is bulky, and Compress Spring causes camber of spring to be difficult for recovering after long-time compression easily, so that the reset capability of spring decline, thereby the working life of having reduced spring.Traditional single-acting executor usually can descend because of the reset capability of Compress Spring, and the difficulty so that single-acting executor resets valve opening occurs or closes phenomenon not in place.
The model utility content
For the problems referred to above, the utility model provides a kind of novel electromechanical liquid integrated single-acting executor, adopt hydraulic oil as flowing medium, the sealed type of plug nitrogen spring resets, thereby optimized structure, guaranteed normally to reset, reduced single-acting executor and driven valve or close valve risk not in place.
The utility model is achieved through the following technical solutions: the liquid integrated single-acting executor of a kind of novel electromechanical, comprise electronic control system, hydraulic system, hand behaviour mechanism, mechanical actuating mechanism, described electronic control system is connected with hydraulic system, described hydraulic system is connected with hand behaviour mechanism, described hydraulic system is connected with mechanical actuating mechanism, described electronic control system comprises controller and actuating motor, described hydraulic system comprises fuel tank, hydraulic integrated valve block, the ratchet pump, described mechanical actuating mechanism comprises oil hydraulic cylinder, piston, the sealed type of plug nitrogen spring, described actuating motor is connected with the ratchet pump, described ratchet pump is connected with hydraulic integrated valve block, described hydraulic integrated valve block is connected with oil hydraulic cylinder by fuel tank, and described sealed type of plug nitrogen spring is installed in the oil hydraulic cylinder.
As preferably, described hydraulic integrated valve block is arranged in the fuel tank, and described hydraulic integrated valve block and fuel tank adopt the Placement of plug-in mounting.
The utility model has taked above-mentioned corrective measure to carry out, its beneficial effect is remarkable: the utility model is reasonable in design, reduce volume, saved material, overcome the deficiency of original Compress Spring, reset to realize that by the sealed type of plug nitrogen spring final controlling element is to unlatching or the closing motion of valve, output torque is large, is quick on the draw, and the energy Rapid reset, long service life has improved reliability of operation and stability.In addition, the hydraulic integrated valve block concentrated setting adopts the plug-in mounting Placement in fuel tank, without external oil pipe, and designs simplification and without leaking leak source, satisfactory for result.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation;
1 is electronic control system among the figure, the 2nd, and hydraulic system, the 3rd, hand behaviour mechanism, the 4th, mechanical actuating mechanism.
Embodiment
The below's contrast accompanying drawing is further described the utility model in conjunction with the embodiments:
With reference to shown in Figure 1, the liquid integrated single-acting executor of a kind of novel electromechanical, comprise electronic control system 1, hydraulic system 2, hand behaviour mechanism 3, mechanical actuating mechanism 4, electronic control system 1 is connected with hydraulic system 2, hydraulic system 2 is connected with hand behaviour mechanism 3, mechanical actuating mechanism 4 respectively, electronic control system 1 comprises controller and actuating motor, hydraulic system 2 comprises fuel tank, hydraulic integrated valve block, ratchet pump, and mechanical actuating mechanism 4 comprises oil hydraulic cylinder, piston, sealed type of plug nitrogen spring.Controller is connected with actuating motor, and actuating motor is connected with the ratchet pump, and the ratchet pump is connected with hydraulic integrated valve block, and hydraulic integrated valve block is connected with oil hydraulic cylinder by fuel tank, and the sealed type of plug nitrogen spring is installed in the oil hydraulic cylinder.Wherein hydraulic integrated valve block is arranged in the fuel tank, adopts the Placement of plug-in mounting.
Working principle:
When controller signals is given regularly, actuating motor rotates and drives the ratchet pump, and oil pressure raise and entered oil hydraulic cylinder by hydraulic integrated valve block this moment, and hydraulic cylinder piston produces thrust under the effect of oil pressure, sealed type of plug nitrogen spring compression this moment, this final controlling element is done 0o～70o or 0o～90o corner; When needs reset, by sealed type of plug nitrogen spring self elastic force pressure, and make the pressure release of oil hydraulic cylinder oil pressure, under the effect of sealed type of plug nitrogen spring, final controlling element is done the corner of 70o～0o or 90o～0o.
What more than enumerate only is specific embodiment of the utility model, and obviously, the utility model is not limited to above embodiment.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should belong to protection domain of the present utility model.
