Abstract
The utility model relates to a stroke control openness indicating mechanism, comprising a pointer shaft and a padding plate, wherein the padding plate is provided with a potentiometer and a bracket; the bracket is provided with two ganged microswitches and an openness indicator; the padding plate is provided with a through hole; the pointer shaft passes through the through hole, central through holes of two cams and a central through hole of a dial in sequence from bottom to top and then is fixedly connected with a pointer; the pointer is configured with the dial face of the dial; the cams are matched with acting parts of the microswitches; the clapboard and a lower frame body form a gear speed-reducing system; and an output gear of the gear speed-reducing system is respectively meshed with a pointer shaft gear and a potentiometer meter. By adopting the structure, the stroke control openness indicating mechanism not only can realize the purpose of stroke control and openness display, but also lead the volume of the whole control mechanism to be small and the manufacturing cost thereof to be low; and the stroke control openness indicating mechanism has simple structure and convenient use.
Description
Technical field
The utility model relates to the stroke indicator of opening on the valve control device, especially a kind of a kind of Stroke Control aperture indicating device that is used for the different rotary number of turns.
Background technique
Valve control device is to utilize manual or electronic many revolutions or the rotating mode of operation of part of carrying out, and drives the opening and closing of valve.Operator promptly may carry out centralized control to valve at a distance, also need to carry out at the scene manually-operable.In departments such as petrochemical industry, water power, metallurgy, nuclear energy, fire-fightings, often use core components such as dish valve, ball valve, stopcock to make rotating valve of part and relevant device, at the very big part turning valve similar devices of heavy caliber, controlling torque, must set up the one-level mechanical reducer again, realize strengthening the purpose of torque.The range controlling mechanism of electric device for valve adopts counter, and the indication mechanism of the unlatching of valve or the position of closing (comprising the electrical signal of exporting its position) is an indicator of opening.These two mechanisms have played and have shown valve element position and carry out the effect of Stroke Control.On present engineering in the employed valve control device, they are two covers mechanisms independently separately, but its driving source has only one, all from the output shaft of electric device for valve.Part turning valve Electric actuator and similar devices, can there be different numerical value the angle of revolution of its spool on demand, for example 90 °, 45 ° or the like.Because counter and indicator of opening are provided with respectively, make that The whole control mechanism volume is big, complex structure, manufacture cost be higher.
The model utility content
The purpose of this utility model just provides a kind of Stroke Control aperture indicating device that integrates Stroke Control and aperture deixis.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of Stroke Control aperture indicating device comprises needle pivot, backing plate; Wherein, potentiometer and support are installed on the described backing plate, described support is installed two duplex sensitive switches and indicator of opening; Described backing plate is provided with through hole, described needle pivot from down and on pass successively behind the central through bore of the through hole of described backing plate, the central through bore of two cams, described dial affixed with pointer, described pointer and described dial card phase configuration, described cam matches with the action component of described sensitive switch; Be provided with gear reduction system between described dividing plate and the framework, the output gear of described gear reduction system respectively with needle pivot gear and potentiometer gear engagement.
The beneficial effect that the utility model brings is: adopts said structure, can realize the purpose that Stroke Control and aperture show, and make little, the low cost of manufacture of The whole control mechanism volume, and simple in structure, easy to use.

Embodiment
As shown in Figure 1, 2, a kind of Stroke Control aperture indicating device comprises needle pivot 1, backing plate 3; Wherein, potentiometer 6 and support 13 are installed on the backing plate 3, support 13 upper surfaces are connected with indicator of opening 4, and the inboard symmetry of support 13 is installed two sensitive switches 10; The central position of backing plate 3 is provided with through hole, described needle pivot from down and on pass successively behind the central through bore of central through bore, indicator of opening 4 of the through hole, overhead cam 8 of described backing plate 3 and following cam 9 affixed with pointer 5, the card phase configuration of pointer 5 and indicator of opening 4; Overhead cam 8 contacts with the action component of sensitive switch 10 respectively with the salient point of following cam 9; Dividing plate 3 is provided with gear reduction system with framework 2, and the output gear 12 of gear reduction system meshes with needle pivot gear 7 and potentiometer gear 11 respectively.The first reduction gear wheel 14 of gear reduction system and central shaft gear engagement, support 13 and dividing plate 3 and framework 2 tighten together by screw.
Working principle: the gear of the stroke output shaft of valve control device and 14 engagements of the first reduction gear wheel of this mechanism, during valve control device work, drive the stroke output shaft, the central shaft gear rotation of stroke output shaft drives the first reduction gear wheel 14 of the gear reduction system of this mechanism, make gear reduction system drive output gear 12 rotations, drive needle pivot 1 and pointer 5 rotations, show valve opening or the process location of closing in real time, simultaneously, output gear 12 drives the potentiometer rotatingshaft by potentiometer gear 11 and rotates, potentiometer 4 output electrical signal, the long-range electric indicating device that links to each other with potentiometer 4 can show valve opening or the process location of cutting out in real time.Close fully or during full open position when valve arrives, corresponding overhead cam 8 or down the bump of cam 9 rotate to corresponding orientation angle, touch corresponding sensitive switch 10, make valve control device stop action, valve opening or close and finish.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
