The valve opening indicator has mechanical valve opening indicator, the machinery valve indicator of opening has housing, there is dial plate the housing top, the rotation input shaft is arranged on the housing, dial plate axle in the middle of housing is arranged in the housing, the dial plate axle is connected with pointer, in the housing, rotate the transmission device that is connected with rotation between input shaft and the dial plate axle.During use, rotation input shaft on the housing is linked to each other with the valve shaft of many rotary types valve, can drive the rotation input shaft rotation on the housing when allowing valve shaft rotate, because the revolution of valve shaft has corresponding relation with the aperture of valve, can indicate valve opening at dial plate by transmission device.
For many rotary types valve, valve shaft need rotate tens to be changeed and could open and close, during with dial plate indication valve opening, it generally is indication valve opening in the dial plate scope of circumference 240 degree ~ 360 degree, so the transmission device in the machinery valve indicator of opening housing is that tens rotations of changeing are become a corresponding transmission device that changes or rotate below the commentaries on classics, transmission device is most important parts in the machinery valve indicator of opening, the precision of the structure influence machinery valve indicator of opening of transmission device.In the prior art, the dial plate in the machinery valve indicator of opening has only a pointer, and precision is lower.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose the higher many rotary types valve opening indicator of a kind of precision.
The utility model is realized with the following method.
Many rotary types valve opening indicator has housing, there is dial plate the housing top, there is the rotation input shaft housing below, on centre in the housing has, the dial plate axle of following direction, the upper end of dial plate axle is connected with first pointer, side in the housing has the countershaft parallel with the dial plate axle, the dial plate axle is with the input gear from top to bottom successively, second duplicate gear, the 4th duplicate gear and output gear, the input gear, second duplicate gear links to each other with the dial plate axle movingly with output gear, the 4th duplicate gear fixedly is connected on the dial plate axle, output gear is connected with second pointer, countershaft is with first duplicate gear that links to each other movingly from top to bottom successively, the 3rd duplicate gear and the 5th duplicate gear, above-mentioned duplicate gear is the lower gear diameter little duplicate gear of diameter that cogs greatly, the input gear is fixed with the rotation input shaft, the input gear is meshed with the lower gear of first duplicate gear, be to cog to be meshed with lower gear successively between first duplicate gear to the, five duplicate gears, cogging of the 5th duplicate gear is meshed with output gear, and the diameter that cogs of the 5th duplicate gear is less than the output gear diameter.
During use, use the rotation input shaft on the housing is linked to each other with the valve shaft of many rotary types valve, can drive the rotation input shaft rotation on the housing when allowing valve shaft rotate, on dial plate, can indicate valve opening.
Be to cog to be meshed with lower gear successively between first duplicate gear to the, five duplicate gears of the present utility model, cogging of the 5th duplicate gear is meshed with output gear, first duplicate gear that is meshed, the 5th duplicate gear and output gear are formed Pyatyi polyphone retarder, the input end of Pyatyi polyphone retarder links to each other with the rotation input shaft by the input gear, the output gear of Pyatyi polyphone retarder is second output terminal, it is first output terminal that the 4th duplicate gear in the Pyatyi polyphone retarder and dial plate axle are fixedly linked, and the rotating speed of first output terminal is greater than the rotating speed of second output terminal.
Pyatyi of the present utility model polyphone retarder can be designed to that many rotary types valve is reduced to one from the tens rotary valve axle revolutions that are closed to unlatching at second output terminal to be changeed or below the commentaries on classics, for example second output terminal is reduced to and rotated 240 degree ~ 360 degree, if 240 degree ~ 360 degree of second output terminal are divided into several calibration, the utility model can be designed to the moving calibration of the second output terminal revolution, allow first output terminal rotate a commentaries on classics, namely second output terminal 240 the degree ~ 360 the degree in each calibration the time, first output terminal revolves goes around, change a calibration that indicates at second output terminal with one of first output terminal, the hour hands that are equivalent to clock and watch are the same with minute hand, can accurately indicate the aperture of many rotary types valve, each calibration of second output terminal is more little, and the validity of indication valve opening is more high.
Transmission device between rotation input shaft of the present utility model and the dial plate axle is Pyatyi polyphone retarder, Pyatyi polyphone retarder has middle output terminal, change a calibration can indicating Pyatyi polyphone retarder output terminal with one of middle output terminal, the validity of indication valve opening is higher.
Below in conjunction with accompanying drawing, the utility model is further described.
