Abstract
The utility model discloses an extra-large flow detecting and cutting device for an intelligent gas meter, and relates to the field of pipe gas meters. The extra-large flow detecting and cutting device for the intelligent gas meter comprises a clarinet (1), a gas meter main circuit board (2) and an electrical machine valve (3). The clarinet (1) is connected with the gas meter main circuit board (2) through a pulse signal wire (9), and the gas meter main circuit board (2) is connected with the electrical machine valve (3) through a valve wire (10). A flow judging and cutting module (12) is arranged inside the gas meter main circuit board (2). The extra-large flow detecting and cutting device for the intelligent gas meter can carry out monitoring to the flow condition of the gas meter simultaneously with achieving intelligent measuring and prepayment of the intelligent gas meter, and when gas flow is overlarge such as a situation caused by a rubber hose falling off, the extra-large flow detecting and cutting device for the intelligent gas meter can close a valve in time, stop gas usage, and effectively reduce the occurring of safety accidents and enable the measuring to be more accurate.
Description
Technical field:
The utility model relates to a kind of intelligent metering device of civil pipeline combustion gas, is specifically related to a kind ofly in metering instantaneous delivery be detected and intelligent decision, when finding the flow super large, can reach alarm and cut off the device of built-in motor valve.
Background technology:
Our domestic employed intelligent civil pipeline combustible gas metering arrangement generally is Intelligent diaphragm gas meter.The intelligence part is equivalent to secondary instrument, and its principle is mounting magnetic steel on the character wheel of gas meter, flow meter base table, cooperates the tongue tube of installing on the character wheel frame, when character wheel rotates, form electronic impulse, the intelligence part records these pulses, deducts fees, the Intelligent treatment such as teletransmission again.Present intelligent gas meter generally all has valve-embedded.But intelligent gas meter has just used the quantity of pulse at present, and the speed of paired pulses is not used.When flow surpassed restriction (maximum range that surpasses the gas upper limit just commonly used or gas meter, flow meter), for example sebific duct came off, and gas meter, flow meter can't detect, the combustion gas of so a large amount of leakages, might cause very serious consequence, if exceed the range ability of gas meter, flow meter, also can cause metering inaccurate.
The utility model content:
The purpose of this utility model provides a kind of intelligent gas meter super-flow and detects and shearing device, it can pass through the ranging pulse interval, can monitor flow velocity, and judge according to the super-flow criterion of prior setting, when being judged to be the flow super large, close self built-in motor valve.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises clarinet 1, gas meter, flow meter main circuit board 2 and motor valve 3, clarinet 1 is connected with gas meter, flow meter main circuit board 2 by pulse signal-line 9, and gas meter, flow meter main circuit board 2 is connected with motor valve 3 by valve line 10.
Be provided with the flow judgement in the described gas meter, flow meter main circuit board 2 and cut off module 12.
The utility model is when the work of table tool, sampling module is converted into one by one pulse with metering signal, pass to gas meter, flow meter main circuit board 2, flow in the gas meter, flow meter main circuit board 2 is judged and is cut off module 12 and monitor each metrical pulse, the time interval between the paired pulses measures, to estimate current instantaneous delivery, the continuous recording instantaneous delivery, and compare with the parameter of prior setting, when occurring flow above setting super-flow parameter, contrast simultaneously lasting duration and the throughput of super-flow, when the two one of restriction that surpass to set, then disable motor valve 3 is also reported to the police, thereby reaches the timely disposal to super-flow, the purpose of accurate-metering and enhancement usefulness gas safety.
The beneficial effects of the utility model are, can be in the intelligent metering and pre-payment of realizing intelligent gas meter, flow situation to gas meter, flow meter is monitored, and when the flow super large occurs (come off such as sebific duct due to), timely valve-off, stop to use gas, the generation of effective decrease safent accident also makes metering more accurate.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model embodiment.
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: it comprises clarinet 1, gas meter, flow meter main circuit board 2 and motor valve 3, clarinet 1 is connected with gas meter, flow meter main circuit board 2 by pulse signal-line 9, and gas meter, flow meter main circuit board 2 is connected with motor valve 3 by valve line 10.
Be provided with the flow judgement in the described gas meter, flow meter main circuit board 2 and cut off module 12.
This embodiment is when the work of table tool, sampling module is converted into one by one pulse with metering signal, pass to gas meter, flow meter main circuit board 2, flow in the gas meter, flow meter main circuit board 2 is judged and is cut off module 12 and monitor each metrical pulse, the time interval between the paired pulses measures, to estimate current instantaneous delivery, the continuous recording instantaneous delivery, and compare with the parameter of prior setting, when occurring flow above setting super-flow parameter, contrast simultaneously lasting duration and the throughput of super-flow, when the two one of restriction that surpass to set, then disable motor valve 3 is also reported to the police, thereby reaches the timely disposal to super-flow, the purpose of accurate-metering and enhancement usefulness gas safety.
The beneficial effect of this embodiment is, can be in the intelligent metering and pre-payment of realizing intelligent gas meter, flow situation to gas meter, flow meter is monitored, and when the flow super large occurs (come off such as sebific duct due to), timely valve-off, stop to use gas, the generation of effective decrease safent accident also makes metering more accurate.
Embodiment:
Referring to Fig. 2, tongue tube 1 is closely fixing with character wheel group 11 in the present embodiment, links to each other with gas meter, flow meter main circuit board 2 by pulse signal-line 9, and motor valve 3 is fixed on air intake opening 6 inside, links to each other with gas meter, flow meter main circuit board 2 by valve line 10.When gas meter, flow meter ventilation work, tongue tube 1 produces the break-make pulse, after gas meter, flow meter main circuit board 2 receives pulse signal, the adjacent pulse interval is measured, to be scaled the instantaneous delivery value recurrent interval, when the instantaneous delivery value surpasses the flow of setting, record is carried out in this pulse, and beginning timing, flows in the gas meter, flow meter main circuit board 2 judge and cut off modules 12 each metrical pulse of monitoring, and when continuous recording umber of pulse reaches setting value, or timing is when reaching setting value, give motor valve 3 inverse currents by valve line 10 immediately, thus disable motor valve 3.And hummer 5 is sent pipe, point out fault at liquid crystal 4 simultaneously.
