Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.

As shown in Figure 1, be a kind of steam-flow meter of pre-payment provided by the utility model, including flowmeter bodies and Controller 7, the flowmeter bodies include shell 3, the flow testing division being set in the shell 3 and are set in shell 3 And the switch valve for controlling flowmeter bodies opening and closing, the flow testing division and switch valve respectively with the controller 7 electrical connection, the controller 7 include for control the switch valve open or close the flowmeter bodies control module and It is set to the surface of the controller 7 and for swiping the card or the induction zone 1 of plug-in card, the induction zone 1 are electrically connected with the controller 7 It connects.Specifically, it when user needs using steam, first needs to be stuck in the induction using the steam flow for prestoring certain amount of money Area 1 swipes the card or steam flow card insertion is entered to the card slot of induction zone 1, and then control module controls the switch valve and starts to supply Control module is the amount used for being equipped with corresponding flow according to the remaining amount of money in the steam flow card being used for simultaneously Limit, the flow testing division detection flows through the flow of the steam of steam-flow meter, when the steam flow for flowing through steam-flow meter reaches When the amount upper limit used to the flow, the control module automatically controls the switch valve and closes, while controller 7 is reminded Sorry, your ticket has not enough value in subscriber card.The above process, user need to first swipe the card and use vapour afterwards, after remaining sum use in subscriber card flowmeter from Dynamic circuit breaker vapour reduces the input of manpower and material resources simultaneously so that it is guaranteed that the theory of " first paying the fees, afterwards with vapour " is achieved.

In the present embodiment, the flow testing division includes the stream for detecting the flow for passing through the steam in the shell 3 Quantity sensor 6, the flow sensor 6 are electrically connected with the control module, and the steam-flow meter of the pre-payment further includes using In the swirl generating body 5 for converting the steam being passed through in shell 3 to circinate steam, the shell 3 includes air inlet and goes out Port, the swirl generating body 5 are set between the air inlet and the flow sensor 6.Specifically, when gas is from shell After 3 air inlet enters, the steam of the swirl generating body 5 is flowed through, powerful whirlpool is generated by swirl generating body 5, so that The signal that flow sensor 6 obtains is stronger, effectively raises flow sensor 6 to the measurement lower limit of fluid, is correspondingly improved Range ability to realize the accurate detection to steam flow, and then realizes the purpose to steam flowrate testing.

Preferably, the inner wall of the swirl generating body 5 plate triangular in shape, the swirl generating body 5 and the shell 3 is solid It is fixed to connect and be arranged in parallel with the end face of shell 3, it is further preferred that the section of the swirl generating body 5 is in isoceles triangle Shape, the shell 3 are in hollow cylindrical shape, the internal diameter of the external diameter of a circle of the swirl generating body 5 and the shell 3 It is identical, so, it is ensured that from swirl generating body 5 pass through after gas be the more regular circinate gas of shape, and then can protect Demonstrate,prove the detection accuracy of flow sensor 6.

In the present embodiment, the switch valve is globe type of control valve 4, and the inner wall of the globe type of control valve 4 and the shell 3 can Be rotatablely connected and be set between the flow sensor 6 and gas outlet, by select globe type of control valve 4 can in shell 3 The problem of wall is bonded completely, anti-leak-stopping vapour.

Further, the controller 7 further includes display screen 8, the display screen 8 can Dynamically Announce residue can steam consumption With the information such as residual amount and all measurement parameters, when can steam consumption be zero (i.e. the amount of money is zero) when, the steam flow Meter is cut steam automatically.In addition, the steam-flow meter of the pre-payment further includes being set in the shell 3 and for detecting shell 3 The pressure sensor of the pressure of interior steam, the pressure sensor are electrically connected with the controller 7, the steam stream of the pre-payment Meter further includes the temperature sensor for being set in the shell 3 and be used to detect the temperature of steam in shell 3, and the temperature passes Sensor is electrically connected with the controller 7, so the pressure value and temperature of steam and can pass through display screen in real-time detection shell 3 8 displays, facilitate the environment in the real-time connecting pipe of staff, improve whole security performance.Include to further increase The safety of the steam-flow meter, the controller 7 further include for manually controlling the urgent of the switch valve opening and closing Button 2 can be manually controlled the switch valve and be opened and closed when emergency (such as leakage vapour) occurs by the danger button 2 Close steam-flow meter.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary, It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition The concrete meaning of language in the present invention.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change It also should be regarded as the protection scope of the utility model into replacement.
