Abstract

The utility model discloses a kind of electric valve aperture photoelectric detection system, it includes the support (2) be arranged on motor (1) shell, photoelectricity is fixed to light pipe (3) in support (2) one end, is positioned at the scale marker (5) that handsetting gear (4) surface of photoelectricity to the electric valve under light pipe (3) scribbles black and white strip.Compared with prior art, the utility model has the advantages that: electric valve aperture can be detected, and structure is simple, volume is little.

Description

Electric valve aperture photoelectric detection system
Technical field
The utility model relates to the detection device of electric valve, is specifically related to a kind of electric valve aperture photoelectric detection system.
Background technique
Chinese patent literature CN203757159U discloses a kind of electric valve Measuring opening device on August 6th, 2014, it comprises electric valve, position sensor transmission shaft is fixedly connected with at the valve rod place of electric valve, this position transducer transmission shaft is connected with position transducer, position transducer is connected with communication cable, position transducer transmission shaft bottom is also provided with graduation indication dish, and position transducer is fixed on the valve body of described electric valve by support.This patent solves in actual moving process and to the problem that electric valve aperture cannot detect and testing precision is not high, improve the accuracy of electric valve Measuring opening because electric valve mechanical transmission lost efficacy.
But because electric valve volume is by the restriction of mounting point, this patent comprises transmission shaft, graduation indication dish, position transducer and support, its volume is larger, will increase the overall volume of electric valve, make the complex structure of electric valve simultaneously, causing trouble increases.
Model utility content
Technical problem to be solved in the utility model is just to provide a kind of electric valve aperture photoelectric detection system, and it can detect electric valve aperture, and structure is simple, volume is little.
Technical problem to be solved in the utility model is realized by such technological scheme, it includes the support be arranged on motor housing, photoelectricity is fixed to light pipe in support one end, is positioned at the scale marker that the handsetting gear surface of photoelectricity to the electric valve under light pipe scribbles black and white strip.
When the handsetting gear of driven by motor electric valve, photoelectricity detects scale marker to light pipe, scale marker position information feed back is returned control unit, just can detect the aperture of electric valve.Because the utility model only needs the support of horizontal positioned, photoelectricity to the small volume of light pipe, and does not need to arrange transmission shaft and graduation indication dish specially, so the utility model volume is little, structure is simple.
Compared with prior art, the utility model has following advantage: can detect electric valve aperture, and structure is simple, volume is little.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model;
In figure: 1. motor; 2. support; 3. photoelectricity is to light pipe; 4. handsetting gear; 5. scale marker.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, the utility model includes the support 2 be arranged on motor 1 shell, and photoelectricity is fixed to light pipe 3 in support 2 one end, is positioned at the scale marker 5 that handsetting gear 4 surface of photoelectricity to the electric valve under light pipe 3 scribbles black and white strip.
Above-mentioned scale marker 5 also can be circular arc labeling, and this circular arc labeling is pasted onto handsetting gear 4 on the surface.

Claims (2)

1. electric valve aperture photoelectric detection system, it is characterized in that: include the support (2) be arranged on motor (1) shell, photoelectricity is fixed to light pipe (3) in support (2) one end, is positioned at the scale marker (5) that handsetting gear (4) surface of photoelectricity to the electric valve under light pipe (3) scribbles black and white strip.
2. electric valve aperture photoelectric detection system according to claim 1, is characterized in that: described scale marker (5) is circular arc labeling.
