But owing to adopting pure mechanical transmission structure, often control accuracy is not high for the existing electronic actuators being applied to valve body field, working life is not long, and requirement on machining accuracy is high, be unfavorable for producing and promote, simultaneously due to when producing, the model of this type electronic actuators and stroke are all fixing, make it can only be applicable to certain a specific straight journey valve body when applying, relevance grade and versatility are all poor.
So be necessary to carry out technological improvement to design a kind of highly versatile and the high electronics independence final controlling element of control accuracy for existing product.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of electronics independence final controlling element that can be applicable to straight journey valve body, which solve electronic actuators poor universality in prior art, the defect that model is single, the advantage such as have that precision is high, highly versatile, easy and simple to handle and life-span are long.
The utility model solves the technological scheme that its technical problem adopts:
A kind of straight journey valve body electronics independence final controlling element, comprise housing, be provided with in described housing and be communicated with the screw rod of valve body and the some gears for the action of drive screw upstream or downstream, described screw rod upper end offers an induction through hole, be provided with in described housing with this induction through hole with the use of, for the photoelectric induction device of described screw rod original point position, when the photosignal that it is launched is sensed by induction through hole, the position of now screw rod is considered as the initial point position of its make-break operation stroke.
As the improvement of technique scheme, described photoelectric induction device comprises the photosignal transmitter and photoelectric signal receiver that are divided into screw rod both sides, when the photosignal of photosignal transmitter is responded to by photoelectric signal receiver by induction through hole, the position of now screw rod is considered as initial point position.
As the improvement of technique scheme, described gear comprises a counting gear, described counting gear is provided with counting hole, and described counting hole place correspondence is provided with photoelectric accounter, and it is by indirectly realizing the control to screw rod upstream or downstream stroke distances to the counting of the counting gear driving number of turns.
The beneficial effect that the utility model brings has:
This electronic actuators product is mainly applicable to straight journey valve body, its screw rod upstream or downstream can realize to valve body with this make-break operation under the effect of motor driving force, principle is simple and control accuracy is high, by the indirect control to screw rod uplink/downlink stroke distances, this product can be made to have versatility and relevance grade better, 7mm can apply this electronic actuators with the straight journey valve body of down stroke and controlled in theory, the utility model delicate structure in addition, the high and longer service life of reliability.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,
Accompanying drawing 1 is internal structure sectional view of the present utility model;
Accompanying drawing 2 is partial structurtes sectional views of the present utility model;
Accompanying drawing 3 is surface structure schematic diagram of the present utility model.
Embodiment
With reference to accompanying drawing 1 to accompanying drawing 3, the utility model is a kind of electronics independence final controlling element being applicable to straight journey valve body, it comprises housing, housing is fixedly connected with by screw thread with the valve body of below, housing internal fixtion is provided with mainboard 3 and gear fixed plate 2 simultaneously, wherein, mainboard 3 is provided with motor 31, in valve body, also includes a through mainboard 3 and gear fixed plate 2, the screw rod 1 being communicated with valve body.
In the course of the work, motor 31 transmission makes the some pinion rotation be fixed on gear fixed plate 2, the latter provides driving force to make screw rod 1 upstream or downstream, the make-break operation to valve body is realized with this, specifically, screw rod 1 of the present utility model action is straight up and down formula, and its upstream or downstream not rely on self to rotate and realize.
Simultaneously, above-mentioned screw rod 1 upper end offers an induction through hole 11, mainboard 3 is provided with this induction through hole 11 with the use of, for the photoelectric induction device of screw rod 1 original point position, concrete, photoelectric induction device comprises photosignal transmitter 32 and photoelectric signal receiver 33, the two is divided into the both sides that screw rod 1 responds to through hole 11, when the photosignal of photosignal transmitter 32 is correctly responded to by photoelectric signal receiver 33 by induction through hole 11, the position of now screw rod 1 is considered as initial point position, as starting point and the benchmark of screw rod 1 stroke.
Above-mentioned some gears comprise a counting gear 21, and this counting gear 21 is provided with counting hole, and counting hole place correspondence is provided with photoelectric accounter 22.Further, photoelectric accounter 22 and motor 31 are connected with PLC, corresponding to the straight journey valve body of different stroke, the number of turns that in PLC, predeterminable different counting gear 21 should rotate, by driving the counting of the number of turns to counting gear 21, indirectly realize the control to screw rod 1 upstream or downstream stroke distances.After being detected that by photoelectric accounter 22 counting gear 21 drives the number of turns to arrive predetermined amount, now screw rod 1 stroke has been considered as, and control motor 31 shuts down by PLC.
In actual applications, when after device power, first origin position detection will be carried out, if screw rod 1 is just positioned at initial point position, then controlled motor 31 by PLC, made screw rod 1 descending by gear drive, if screw rod 1 is not in initial point position, then first should carry out origin position calibration.After the photosensitive catoptric arrangement by photoelectric accounter 22 learns that counting gear 21 drives arrival predetermined amount, valve body make-break operation completes, and motor 31 shuts down, and equipment enters state of dormancy immediately.
But, for the lower subnormal use of support equipment, mainboard 3 should be fixed with some electric capacity 34, by the power down arousal function of electric capacity 34, screw rod 1 inverted running can be made after equipment dead electricity to return initial point position, this for raising equipment precision and working life all of great advantage.
Visible electronic actuators principle is simple and control accuracy is high, by the indirect control to screw rod 1 uplink/downlink, product can be made to have versatility and relevance grade better, and 7mm can apply this electronic actuators with the straight journey valve body of down stroke and controlled in theory.The utility model delicate structure, the high and longer service life of reliability.
It should be noted that, the above is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned mode of execution, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
