Abstract
The utility model relates to an anti overpressure or under pressure prepaid intelligent gas meter which can shut off a gas inlet channel automatically under the conditions of the gas supply pressure rising or the faint pressure and even the gas cut-off. The prepaid intelligent gas meter consists of a main gas meter having a gas inlet and a gas outlet, a gas chamber, a gas meter and a display. A port valve seat is arranged on the gas inlet of the gas meter; a pressure sensor is arranged above the valve seat, an electrical valve controlled by a control circuit board having a valve seat port seal cap is arranged within the valve seat; an output control signal of the control circuit board is controlled by the output signal of the pressure sensor; an electrical valve reset button connected with the control circuit board is arranged on a panel on a surface of the shell. When the gas of a pipeline is in overpressure or under pressure, the pressure sensor transports a detected signal to the control circuit board which controls the electrical valve to turn off the valve and cut off the gas channel automatically so as to protect the security of a user and the meter.
Description
Affiliated technical field
The utility model belongs to measurement of gas flow Instrument technology field, a kind ofly raises or pressure is faint even cut off the superpressure preventing of air intake opening gas circuit or under-voltage prepayment intelligent gas meter, flow meter when stopping the supple of gas or steam automatically at gas supply pressure but relate to.
Background technology
Pipe gas used in everyday, for security consideration, general pressure approaches normal pressure, so the gas meter, flow meter of user side installation at present also all is to use in the normal pressure scope.Because the pressure during gas supply all is to be defeated by the user again after transferring low pressure to by high pressure, in case voltage-regulating system breaks down, cause high-pressure gas to enter the user, will make gas meter, flow meter gently then damaged or measure inaccurate, heavy then cause the gas meter, flow meter blast, the initiation security incident.Moreover, the situation that air feed interrupts suddenly takes place in gas company for various reasons sometimes in the air feed process, as fail in time to notify the every family valve-off, some users tend to because carelessness etc. are former thereby forget valve-off, like this after pipeline recovers air feed, combustion gas will be leaked in a large number and be caused that accident takes place, and brings very big harm to the user.
The utility model content
The purpose of this utility model is the problem that prior art exists is solved; but and then provide a kind of structural principle simple and practical, can under superpressure or under-voltage condition, realize closing the superpressure preventing of protection or under-voltage prepayment intelligent gas meter, flow meter; this gas meter, flow meter can cut off the combustion gas gas circuit of air intake opening immediately in air feed generation superpressure or when under-voltage, thereby has protected the safety of user and Biao.
The technical solution that adopts is provided with a port valve seat at the air intake opening place of gas meter, flow meter for achieving the above object, above valve seat, be provided with a pressure transducer, in valve seat, be provided with a electrically-controlled valve by the band valve seat mouth capping of control circuit board control, the output control signal of control circuit board is controlled by the output signal of pressure transducer, is provided with the electrically-controlled valve reset button that connects with control circuit board on the watchcase panel.User installation behind this gas meter, flow meter, at supply gas pressure just often at ordinary times, pressure transducer does not have signal output, at this moment, as long as in the storer of precharging circuit residue tolerance is arranged, supply voltage meets the requirements, the import electrically-controlled valve of table just can normally be opened, and the user can normally use combustion gas; When supply gas pressure raises, the pressure that detects in the air chamber with the pressure transducer of showing on the body is installed to raise, when pressure is increased to setting value, pressure transducer outputs signal to control circuit board, control circuit board closes valve control to electrically-controlled valve immediately, cut off air intake opening combustion gas gas circuit, gas meter, flow meter is not damaged by gases at high pressure, thereby protected the safety of table; When intake pressure is reduced to setting value, pressure transducer outputs signal to control circuit board control electrically-controlled valve equally and cuts out, and because of the user forgets valve-off accidents such as a large amount of explosion caused by leakage poisonings of combustion gas takes place to come behind the gas to guarantee to be unlikely to after combustion gas is stopped the supple of gas or steam again.After in case electrically-controlled valve is closed, must be normal, residue tolerance is arranged in the table, when supply voltage meets the requirements, can open gas meter, flow meter once more by manual operation electrically-controlled valve reset button at supply gas pressure.
Description of drawings
Accompanying drawing is the structural representation of a specific embodiment of the utility model.
Embodiment
Referring to accompanying drawing, prepayment intelligent gas meter, flow meter described in the utility model is made up of the gas meter, flow meter main body 1 of bringing gas port 2 and gas outlet 11 into, air chamber 5 and tolerance counter 13 and display 8.Air intake opening 2 places in gas meter, flow meter main body 1 are provided with a port valve seat, an electrically-controlled valve 3 is housed in valve seat inside, the valve seat mouth capping that can open, close the valve seat port is housed on the electrically-controlled valve 3, on the watchcase wall above the valve seat, is equipped with by detecting the pressure transducer 6 that hole 4 detection table body air chambers, 5 internal pressures change; Be provided with in the body at table user's gas consumption is carried out pre-payment control, supply gas pressure generation superpressure or closes the control circuit board 7 of valve control when under-voltage, control circuit board 7 is when carrying out advanced charge gas control system to the combustion gas user, but the working pressure in the his-and-hers watches body air chamber 5 is implemented monitoring by sensor 6, and implements electrically-controlled valve 3 is opened and closed the control of action; During work, then by the signal condition decision of pressure transducer 6 outputs, pressure transducer 6 can both send control signal to the control signal state that control circuit board 7 sends under gaseous tension rising or reduction two states; Also be provided with the display 8 that is used for residue tolerance and duty in the indicator gauge on the body at table, be used for reset button 9 that electrically-controlled valve resets, be used for the review button 10 of residue tolerance and duty in the look-up table.Number in the figure 12 is a power supply.
