Abstract
The utility model relates to an electronic house-using combustion-gas meter which comprises a casing, a support component is arranged in the casing and is provided with a rotatable main shaft, the top part of the main shaft is provided with a magnet which runs along with the main shaft, the magnet can be a magnetic ring or magnetic steel, the external part of the casing is provided with one or a plurality of magneto sensors, the magneto sensor can be arranged in the alternating field generated by the magnet, electric signals of the magneto sensors are processed and operated by a CPU and then sent to a liquid crystal display screen positioned above the casing. When the gas passes through the combustion-gas meter, the main shaft runs along with the gas stream and drives the magnetic ring or the magnetic steel to rotate together, thereby the alternating field is generated at the position of the magneto sensors, the magneto sensors are caused to generate the electric signals that the frequency is proportional to the gas flow quantity, then the signal is processed and operated by the CPU, and the gas flow quantity passing through the combustion-gas meter is directly displayed on the liquid crystal display screen.
Description
Technical field
The utility model relates to the family gas meter, flow meter, relates in particular to a kind of electronic type family gas meter, flow meter
Background technology
Existing family with gas meter, flow meter be the flow signal of gas is transferred to the mechanical rotation signal after, pass through multi-change speed again, on mechanical counter, demonstrate gas flow.When gas passes through gas meter, flow meter, main shaft on the bracket component produces the mechanical rotation that is directly proportional with the flow size, in order to guarantee that this mechanical rotation passes to the reliability of off-balancesheet in show, on support, main shaft is rotated processings of slowing down (generally will through bi-level treatment), pass to off-balancesheet by magnetic coupling transmission (or direct through-drive) again.Then,, determine ratio of gear, make this rotation size of (generally will through three-step timing) after speed governing just can represent size, and on mechanical counter, show by the gas flow of gas meter, flow meter to the rotation of passing to off-balancesheet and the detection of flow magnitude relationship.
From above-mentioned principle of work as can be known, there is following shortcoming in the gas meter, flow meter of this mechanical structure: 1, gas meter, flow meter will pass through multistage gear drive (having one-level at least is the worm and wheel transmission), has increased mechanical resistance, reduces gas meter, flow meter sensitivity.2, pass in the mechanical drive of off-balancesheet in table, as use the magnetic coupling transmission, rotating speed can not be too fast, otherwise, when off-balancesheet is rotated, be easy to generate and beat or skid.As directly using through-drive, will increase a motive seal, thereby reduce the gas meter, flow meter sealingly secure, cause working pressure to reduce.3, since frictional resistance exist, thereby the rotation of passing to off-balancesheet is determined that with the detection of flow magnitude relationship ratio of gear has increased difficulty, and measuring accuracy is not high, will could determine through repeatedly testing usually, has reduced production efficiency yet.
Summary of the invention
For overcoming the defective that existing machinery formula family exists with gas meter, flow meter, the utility model provides a kind of electronic type family gas meter, flow meter.
The technical scheme that the utility model adopted is: a kind of electronic type family gas meter, flow meter, comprise housing, be provided with bracket component in the housing, bracket component is equipped with rotatable main shaft, a magnet with spindle operation is equipped with at the top of main shaft, magnet can be magnet ring or magnet steel, outside is equipped with one or many magneto-dependent sensors, magneto-dependent sensor can be in the alternating magnetic field that magnet produces, the electric signal of magneto-dependent sensor handle by central processing unit and computing after flow to the LCDs that is positioned at above the housing.When gas passes through gas meter, flow meter, main shaft is with air-flow rotation and drive magnet ring or magnet steel rotates, thereby produce alternating magnetic field at the magneto-dependent sensor place, make magneto-dependent sensor produce the electric signal that frequency is directly proportional with gas flow, by central processing unit (CPU) this signal is handled and computing then, on LCDs, directly shown the flow of gas by this gas meter, flow meter.
The utlity model has following beneficial effect: 1, magnet ring or magnet steel directly are installed as magnetic field generator on the main shaft of support, have been deleted the various gear drive of former mechanical gas table, significantly reduce mechanical resistance, improved gas meter, flow meter sensitivity.2, transmit the gas flow signal with magnet ring or magnet steel and magneto-dependent sensor, realize that the gas meter, flow meter inside and outside finishes isolation, improved the working pressure of gas meter, flow meter sealingly secure and gas meter, flow meter.3, because the mechanical signal of flow has transferred electric signal to, can carry out numeral to the gas meter, flow meter parameter by button is provided with and improves the gas meter, flow meter measuring accuracy, thereby changed in the past and can only adjust the gas meter, flow meter precision by the way of changing governor gear change speed ratio, simplify production routine greatly, improve gas meter, flow meter measuring accuracy and qualification rate.4, after the gas meter, flow meter flow signal was realized electronic digitalizing, further upgrading provided convenience to product.
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
