Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, an anti-interference dual-display gas turbine flowmeter includes a counter support 10, a fixed shaft 110 is provided on the counter support, a plurality of collecting character wheels 20 for mechanical recording of numerical values, which can be earned, are hinged on the fixed shaft 110, a rotatable induction wheel 30 is provided at a side of the collecting character wheel located at an end portion of the counter support, a magnetic steel a310 and a magnetic steel B320 are arranged on the induction wheel 30, a sensor 40 for inducing the magnetic steel a310 and the magnetic steel B320 is provided at a side of the induction wheel, and the magnetic steel a and the magnetic steel B are arranged in a staggered manner along a circumferential direction.
In this embodiment, the magnetic signals of the magnetic steel a and the magnetic steel B triggering the induction are different.
In this embodiment, the magnetic steel a310 and the magnetic steel B320 are spaced by 180 °, and a fixed shaft is disposed in the middle of the sensor wheel 30, and the fixed shaft is rotatably connected to the counter support 10 through a bearing.
In this embodiment, a raised annular transmission convex tooth 210 is arranged on the side portion of the collecting character wheel positioned at the end portion of the counter support 10, a transmission gear 50 arranged perpendicular to the collecting character wheel is hinged on the counter support, the induction wheel is coaxially provided with a driven gear 330 capable of being meshed with the transmission gear, and the transmission gear 50 is meshed with the transmission convex tooth 210.
The anti-interference double-display gas turbine flowmeter adopted by the utility model is provided with an anti-vibration low-frequency flow sensor, the correcting instrument senses pulse signals when the magnetic steel A310 rotates along with the shaft and passes through the front side of the sensor 40, the quantitative accumulated calculation of the flow is carried out, and then the locking signals are not influenced by vibration any more to generate errors of repeated metering. When the shaft continues to rotate the magnetic steel B to the sensor, the sensor transmits a signal B to the integrating instrument, and the unlocking of the magnetic steel A is instructed by the unlocking sensor, so that the magnetic steel A can be measured again by the sensor. Because the magnetic steel A and the magnetic steel B have different magnetic signals and have a certain phase difference, the metering locking of the magnetic steel A and the unlocking interaction of the magnetic steel B cannot interfere with each other, so that the flow meter integrating instrument and the mechanical character wheel are ensured to be consistent in display.
If the utility model discloses or relates to parts or structures which are fixedly connected to each other, the fixedly connected parts can be understood as follows, unless otherwise stated: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).
In addition, terms used in any technical solutions disclosed in the present invention to indicate positional relationships or shapes include approximate, similar or approximate states or shapes unless otherwise stated.
Any part provided by the utility model can be assembled by a plurality of independent components or can be manufactured by an integral forming process.
Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the utility model or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the utility model as defined by the appended claims.
