Abstract
The utility model discloses a kind of electric valve with opening indicator device, comprise valve body, in valve body, be provided with motor, by the retarder of motoring, the electric actuator driven by retarder, and the valve rod driven by electric actuator, be also provided with opening indicator device in valve body; Opening indicator device comprises the transmission shaft driven by valve rod, and transmission shaft stretches out valve body and the one end of stretching out valve body is provided with triggering pointer; Centered by transmission shaft, valve body surface is provided with circular scale line, triggers pointed graduation line; Also comprise and graduation line miniature location trigger one to one, trigger when pointer rotates and touch location trigger, location trigger is triggered and sends trigger signal to controller.This model utility sends position signal by location trigger to controller, and avoids and simple rotate by motor the opening amount signal sent and carry out the bad of aperture erroneous judgement, effectively improves aperture control accuracy.
Description
Technical field
The utility model relates to electric device for valve technical field, particularly a kind of electric valve with opening indicator device.
Background technique
Electric valve is widely used in Cemented filling field, and in some important events, higher to the Security of electric valve, reliability requirement.Electric valve utilizes electric actuator control valve, thus realize the Kai Heguan of valve, and the driving of electric actuator, by motor driving reducer speed change, reduces rotating speed, increases moment of torsion, and then actuate valve stem nut does and rotates or elevating movement.Wherein, the valve position of electric valve self is then by the mechanical indicator display on opening indicator device.But, find in electric valve actual moving process, sometimes due to the mechanical failure of the driving mechanism of electric valve, even if there is aperture variable signal to send (sending as long as motor rotation just has signal), but valve body itself does not have corresponding actions, the mechanical indicator on valve opening indicating device is caused normally not show.How to solve the electric valve mechanical transmission occurred in actual moving process to lose efficacy the problem causing aperture normally to indicate, for the Security, the reliability that improve important events electric valve, ensure that conveyance conduit stable operation has great importance.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of electric valve with opening indicator device, to improve the control efficiency of electric device for valve, avoids the problem that the aperture caused because mechanical transmission lost efficacy cannot normally indicate.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of electric valve with opening indicator device, comprise valve body, motor is provided with in described valve body, by the retarder of described motoring, the electric actuator driven by described retarder, and the valve rod to be driven by described electric actuator, be also provided with opening indicator device in described valve body;
Described opening indicator device comprises the transmission shaft driven by described valve rod, and described transmission shaft stretches out described valve body and the one end of stretching out described valve body is provided with triggering pointer; Centered by described transmission shaft, described valve body surface is provided with circular scale line, graduation line described in described triggering pointed; Also comprise and described graduation line miniature location trigger one to one, touch described location trigger when described triggering pointer rotates, described location trigger is triggered and sends trigger signal to controller.
Pass through technique scheme, a kind of electric valve with opening indicator device that the utility model provides, it has the opening indicator device of location trigger by arranging, position signal can be sent to controller by location trigger, and avoid and simple rotate by motor the opening amount signal sent and carry out the bad of aperture erroneous judgement, effectively improve aperture control accuracy.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is the structural representation of a kind of opening indicator device disclosed in the utility model embodiment.
Numeral in figure:
11. valve body 12. transmission shafts 13. trigger pointer
14. graduation line 15. location triggers
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
With reference to figure 1, the electric valve of what the utility model provided have opening indicator device, comprise valve body 11, motor is provided with in valve body 11, by the retarder of motoring, the electric actuator driven by retarder, and the valve rod driven by electric actuator, be also provided with opening indicator device in valve body 11;
Opening indicator device comprises the transmission shaft 12 driven by valve rod, and transmission shaft 12 stretches out valve body 11 and the one end of stretching out valve body 11 is provided with and triggers pointer 13; Centered by transmission shaft 12, valve body 11 surface is provided with circular scale line 14, triggers pointer 13 and points to graduation line 14; Also comprise and graduation line 14 miniature location trigger 15 one to one, trigger when pointer 13 rotates and touch location trigger 15, location trigger 15 is triggered and sends trigger signal to controller.
A kind of electric valve with opening indicator device that the utility model provides, it has the opening indicator device of location trigger 15 by arranging, drive transmission shaft 12 to rotate when valve rod rotates, and then drive triggering pointer 13 to rotate, trigger the location trigger 15 triggering diverse location when pointer 13 rotates one by one, and then position signal can be sent by location trigger 15 to controller, and avoid and simple rotate by motor the opening amount signal sent and carry out the bad of aperture erroneous judgement, effectively improve aperture control accuracy.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of above-described embodiment, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
