Description
Technical field
The utility model relates to gas-fired equipment field, particularly relates to a kind of ultrasonic wave gas meter.
Background technology
Along with ultrasonic wave gas meter widespread use socially, more and more be subject to the favor of user, the valve in the main outer portion of ventilation of existing ultrasonic wave gas meter opens and closes, and is set to user like this and brings a lot of inconvenience, automatically can not open and close the conveying of combustion gas; And can not prevent some client from usurping combustion gas, particularly those quantitatively use the client of combustion gas, its combustion gas use amount uncontrollable.
Utility model content
The purpose of this utility model is that just above-mentioned the deficiencies in the prior art part being provided to a kind of can not need manually opened and close and can prevent client's malice from usurping the ultrasonic wave gas meter of combustion gas.
The utility model realizes the technical scheme that above-mentioned purpose takes: a kind of ultrasonic wave gas meter, it comprises the upper shell and lower house that connect down through O-ring seal, described upper shell is provided with fuel gas inlet and gas outlet, the electrovalve for opening and closing passage between fuel gas inlet and gas outlet is provided with in described upper shell inner chamber, also be provided with the reflex channel for measuring gas flow in described upper shell, upper shell exterior lateral sides is provided with flow indication screen; The card reader for plug-in mounting control card is provided with in described lower house, the below that described lower house outside is positioned at flow indication screen side is provided with battery case, be provided with in described battery case for the lithium battery to the power supply of card reader, electrovalve and flow indication screen, the outer setting of battery case has battery case cover plate.
Lithium battery described in the utility model is fixed by lithium battery gland.
The outside conjunction by table cover diaphragm seal cover of flow indication screen described in the utility model has table cover.
Principle of the present utility model is: the utility model utilizes the storage card can fixing combustion gas use amount to be controlled the conveying use amount of combustion gas by card reader, when storage card inserts card reader, lithium battery starts as electrovalve and the power supply of flow indication screen, and blast tube opened by electrovalve; When combustion gas use closed by needs, extract storage card, electrovalve power-off automatic self-closing gas passage; Or when the combustion gas use amount of the storage in storage card exhausts, also can auto-breaking thus close blast tube, at this moment, the combustion gas payment point payment that client needs to bring storage to snap into and specifies is supplemented with money for storage card.
The beneficial effect that the utility model takes technique scheme to bring is: gas meter, flow meter structure of the present utility model is simple, manually can open blast tube, safe and convenient to use; Can prevent client's malice from usurping the generation of gas condition simultaneously.
