Abstract
The utility model provides a digital quantity sealing adjustable valve, which comprises a stepping motor stator, a stepping motor rotor, a valve housing, a double-valve base, a left valve core, a right valve core, a ball nut and a ball screw, and is characterized in that the stepping motor stator is fixed on the valve housing, the ball nut is fixed with the stepping motor rotor to drive the ball screw to drive the two valve cores, the double-valve base does linear movement in an inner hole, the ball nut and the ball screw are arranged in the stepping motor rotor, and the ball nut and the stepping motor rotor are integrated. A square shaft of the tail end of the ball screw is inserted into a square hole of an anti-rotating block fixed with a stepping motor back cover. The utility model is arranged in an industrial automation control system, always maintains that flow and pressure of the gas or the liquid in the system are stable, and can change the flow and pressure of the system according to the feedback signal of the control system.
Description
Affiliated technical field
The utility model relates to a kind of actuator of industrial automation control system, and especially being fit to can adjustments of gas or fluid flow, the modulating valve that can seal again.
Background technique
Current, used modulating valve on industrial automation control system, major part is the analog amount modulating valve, for example: pneumatic diaphragm control valve, electronic computer sends digital quantity signal, through after the digital-to-analog conversion, become the analog signals of 4～20ma, the regulating and controlling valve is implemented to regulate, this modulating valve complex structure, big, the Heavy Weight of volume, and system is furnished with digiverter and compressed air gas source in addition.
Summary of the invention
The utility model provides a kind of digital quantity sealed-regulating valve, and it is installed in the industrial automation control system, remains the flow and the pressure stability of gas in the system or liquid.And can change the flow and the pressure of system according to the feedback signal of control system.Can be promptly, exactly industrial automation control system is carried out open loop or closed-loop adjustment.
Sealed-regulating valve, comprise stepping motor stator, stepping motor rotor, valve housing, bivalve gate seat, left spool, right spool, ball nut and ball screw, it is characterized in that: the stepping motor stator is fixed on the valve housing, ball nut and stepping motor rotor are fixed, drive ball screw and drive two spools, in bivalve gate seat endoporus, do straight line motion.Ball nut and ball screw are packed in the stepping motor rotor, and ball nut and stepping motor rotor are made of one.The terminal square shaft of ball screw inserts in the square hole of the anti-switch block of fixing with the stepping motor bonnet.Soft sealing material embeds the big footpath of spool, realizes damming sealing.
The beneficial effects of the utility model are that compact structure is firm, volume is little, in light weight.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an embodiment's of the present utility model longitudinal section tectonic maps.
Among the figure: 1. valve housing, 2. valve inlet, 3. bivalve gate seat, 4. right spool, 5. left spool, 6. set screw, 7. seal ring, 8. seal ring, 9. stepping motor stator, 10. stepping motor stator, 11. bearings, 12. stepping motor bonnets, 13. set screw, 14. lead-in wires, 15. anti-switch blocks, 16. gland nuts, 17. locking nut, 18. ball nuts, 19. balls, 20. ball screws, 21. valve export, 22. blanking covers, 23, soft seal.
Embodiment
In the embodiment shown in fig. 1, the industrial control system computer sends digital quantity signal, through lead-in wire (14), enters stepping motor stator (10), forms rotating magnetic field, stepping motor rotor (9) rotation under two bearings (11) support.The ball nut (18) of taking interference fit with stepping motor rotor (9) endoporus and becoming one rotates thereupon.The terminal square shaft of ball screw (20) inserts in the square hole of the anti-switch block of fixing with the stepping motor bonnet (15), ball screw is done to seesaw, with ball screw (20) right spool (4) and the left spool (5) that is threaded togather, endoporus at bivalve gate seat (3) is done straight line motion, changes flow area.At left and right spool (4,5) large-diameter portion branch soft seal (23) is housed, to realize the two sealings of damming of pipe-line system.
