Abstract
The utility model discloses a novel gas meter which comprises a gas inlet, a shell body, a gas outlet and a gas metering system which is arranged inside the shell body. The novel gas meter is characterized by comprising a filter device which is arranged inside the shell body, and is connected with the gas inlet, wherein the filter device comprises a filter body, a sticking material layer and support lugs, the support lugs are arranged on a cylinder body portion of the filter body, and the sticking material layer is adhered on the inner surface of a spherical body portion of the filter body. After gas enters the filter device, impurities existing in the gas can be detained in the filter device, and deposit in a deposit room, corrosive gas is fully absorbed by the sticking material layer, and thus metering accuracy and service life of the novel gas meter are effectively improved.
Description
Technical field
The utility model relates to the gauging instrument in air feed field, is specifically related to a kind of gas meter, flow meter that can filter entering the combustion gas that is being mingled with impurity in table.
Background technology
The most gas meter, flow meter is mainly the metering for rock gas, use the place of artificial coal gas at some, because of the contained sulphuric dioxide of artificial coal gas and other impurity too much, larger to the corrosion of gas meter, flow meter mechanical part, thereby be down to 1-2 the serviceable life that makes gas meter, flow meter, do not reach 10 years service time of national Specification gas meter, flow meter far away; Impurity also can be attached on the drive disk assembly of gas meter, flow meter, affects significantly the accurate-metering of gas meter, flow meter.
For this reason, a kind of can impurity screening, the gas meter, flow meter of absorption corrosive gas demands urgently being developed.
The utility model content
For above-mentioned deficiency of the prior art, the utility model provide a kind of can impurity screening, the gas meter of absorption corrosive gas, it has the advantages such as simple in structure, reasonable in design.
In order to reach the foregoing invention purpose, the technical solution adopted in the utility model is for providing a kind of gas meter, the gas metering system that it comprises air intake opening, housing, gas outlet and is arranged on enclosure interior, it is characterized in that: also comprise the filtration unit that is arranged on enclosure interior and is connected with air intake opening, described filtration unit comprises filtration body, stickum layer and journal stirrup, and described journal stirrup is arranged on the barrel portion that filters body; Described stickum laminating is attached to the inside surface of the spheroidite part of filtering body.
Preferably, the barrel portion above described journal stirrup is provided with an annular groove that is used for installing O-ring seal.
Preferably, the gas metering system touching position of described gas outlet and enclosure interior is provided with O-ring seal.
Preferably, the material of described filtration unit is the polyoxymethylene material.
The beneficial effects of the utility model are:
1, after combustion gas entered filtration unit, the impurity that exists in combustion gas just can be trapped in filtration unit and be deposited on the mud chamber, and corrosive gas can be absorbed fully by the stickum layer, thereby has effectively improved measuring accuracy and the serviceable life of gas meter, flow meter;
The O-ring seal of the O-ring seal that 2, arranges between air intake opening and filtration unit and gas outlet and the touching position setting of gas metering system has improved the sealing of gas meter, flow meter effectively, the phenomenon of having avoided gas meter, flow meter to leak.

Fig. 2 is the structure for amplifying schematic diagram of filtration unit.
Wherein, 1, air intake opening; 2, filtration unit; 21, filter body; 22, stickum layer; 23, mud chamber; 24, annular groove; 25, journal stirrup; 3, housing; 4, gas outlet; 5, O-ring seal.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As depicted in figs. 1 and 2, this gas meter comprises air intake opening 1, housing 3, gas outlet 4 and is arranged on the gas metering system of enclosure interior, it is characterized in that: also comprise being arranged on the filtration unit 2 that housing 3 is inner and be connected with air intake opening 1, described filtration unit 2 comprises filtration body 21, stickum layer 22 and journal stirrup 25, and described journal stirrup 25 is arranged on the barrel portion that filters body 21; Described stickum layer 22 is attached to the inside surface of the spheroidite part of filtering body 21.
The barrel portion of described journal stirrup 25 tops is provided with an annular groove 24 that is used for installing O-ring seal 5; The gas metering system touching position of described gas outlet 4 and housing 3 inside is provided with O-ring seal 5; The material of described filtration unit 2 is the polyoxymethylene material.
After combustion gas entered filtration unit 2, the impurity that exists in combustion gas just can be trapped in filtration unit 2 and be deposited in mud chamber 23, and after corrosive gas can be absorbed fully by stickum layer 22, then combustion gas entered metering cavity from the valve of gas meter, flow meter.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement to the utility model, these improvement also fall in the protection domain of the utility model claim.
