Description
Technical field the utility model relates to the stroke indicator of opening on a kind of electric device for valve, in particular for a kind of Stroke Control aperture indicating mechanism on the different rotary number of turns or the angular valve valve electric device.
The functional part of an important demonstration output on the background technology stroke indicator of opening electric device, the switch of the reflection device that it is real-time and operation duty.Electric device generally all utilizes electronic or manual mode is carried out many revolutions or partly rotating operation, for example is used to drive the valve opening and closing or drives the hand motor speed regulator that the power station guide vanes of water turbine opens and closes.Operating personnel promptly can also can control at the scene at a distance above-mentioned equipment being carried out centralized control.Be widely used at industrial sectors such as petrochemical industry, water power, metallurgy, nuclear energy.The position display mechanism (comprising the electric signal of exporting its position) of the opening and closing of valve, the moving speed regulator of hydraulic turbine torch is an indicator of opening.Number or rotation angle have nothing in common with each other because the requirement of various service conditions, electric device output shaft are turn-taked, and the display disc on the electric device can only display device from the standard-sized sheet to the complete shut-down in 270 ° of scopes.In order to satisfy this requirement, according to the difference of output shaft rotating cycle or corner, will be equipped with the different indicator of opening of reduction gear ratio, make that this mechanism of indicator of opening cannot be general.
Summary of the invention problem to be solved in the utility model provides a kind of Stroke Control aperture indicating mechanism; Its objective is is in operation at electric device realizes the universalization of aperture indicating mechanism.
To achieve these goals, the scheme that its technical matters that solves the utility model adopts is: pointer, microswitch, display disc, four groups of duplicate gears, change gear, cam, selector shaft is installed in upper plate respectively and is fixed on its gear shaft separately by fixed head, wherein, the spring contact that stretches out and the cam of microswitch contact, in change gear, the polygon groove of locking ball one end and selector shaft, the other end contacts with spring in the hole of enclosed shape, potentiometer places a side of upper plate, gear is meshed with the potentiometer gear respectively, the endoporus of change gear and the way of contact of selector shaft are for sliding up and down, be shaped as polygon, be provided with locating slot in the one side, when change gear axially during up or down displacement, can mesh with the duplicate gear of diverse location, in the hope of the different output speed of change gear.
After adopting said method, applicable to requiring the turn-take electric device of number or different rotary angle of difference;
The mode of polygonal selector shaft and change gear structure, elasticity location, the upper and lower displacement gear shift is easy to adjust easily;
The combination of cam and microswitch, the optional position in the switching process of electric device can be sent any reference mark signal.
