Abstract
The utility model relates to an anti -interference leak protection gas table, including watchcase (1), its characterized in that: watchcase (1) inside is provided with one section air duct (4), and air duct (4) communicate with each other with outlet duct (3), watchcase (1) comprises shell (1.1) and inner shell (1.2) be provided with the anti -electromagnetic interference device between shell (1.1) and inner shell (1.2), the anti -electromagnetic interference device includes electromagnetic shield net (5), anti -interference magnetic core (6) and electromagnetic absorption board (7), shell (1.1) is connected to electromagnetic shield net (5), and inner shell (1.2) is connected in electromagnetic absorption board (7), and anti -interference magnetic core (6) are located between the electromagnetic shield net (5) and electromagnetic absorption board (7). The utility model discloses anti -electromagnetic interference can the reinforce, and can reduce the economic loss of gas company.
Description
Technical field
The utility model relates to a kind of gas meter, flow meter, particularly relates to a kind of anti-interference anti-gas-leak gas meter, flow meter.Belong to technology of instrument and meter field.
Background technology
The gauging table of general gas meter, flow meter is installed on escape pipe place, and combustion gas is by carrying out counting statistics during gauging table.In order to reduce the production cost of gas meter, flow meter, generally made of plastic by being in inner a section of being connected with escape pipe of watchcase, so just be easy to cause user to carry out robber's gas gas leakage behavior, only need use heated iron wire that plastic tube is scalded a hole just can allow combustion gas directly use without gauging table, and this loss for gas company is larger.
In addition; current; gas meter, flow meter can be mounted in kitchen usually; usually the various household electrical appliance that can produce high-intensity magnetic field are had in kitchen; such as micro-wave oven, electromagnetic oven, lampblack absorber etc., when strong external magnetic field interference source is near gas meter, flow meter, can affect the correct metering of gas meter, flow meter; the system of some intelligent gas meter understands automatic-closing valve and lock machine, and user from new plug subscriber card or can only please overhaul, unlock in gas company.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of anti-interference anti-gas-leak gas meter, flow meter, and anti-electromagnetic interference capability is strong, and can reduce the economic loss of gas company.
The purpose of this utility model is achieved in that a kind of anti-interference anti-gas-leak gas meter, flow meter, comprises watchcase, has draft tube and escape pipe in watchcase outer setting, and described watchcase inside is provided with one section of wireway, and wireway communicates with escape pipe; Described watchcase is made up of shell and inner casing, electromagnetic interference resistant device is provided with between described shell and inner casing, described electromagnetic interference resistant device comprises electromagnetic screen net, anti-interference magnetic core and electromagnetic absorption plate, described electromagnetic screen net connected with outer casing, electromagnetic absorption plate connects inner casing, and anti-interference magnetic core is between electromagnetic screen net and electromagnetic absorption plate.
Compared with prior art, the beneficial effects of the utility model are:
1, one section of wireway made with metal material be connected with escape pipe is set in watchcase inside, can prevents user from scorching the modes such as wireway to carry out robber's gas gas leakage behavior with heating iron wire, reduce the economic loss of gas company.
2, electromagnetic interference resistant device is set between the inside and outside shell of table, can efficiently by various blocking electromagnetic waves outside gas meter, flow meter, or to be absorbed, make gas meter, flow meter remain normal work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the electromagnetic interference resistant device in the utility model.
Wherein:
Watchcase 1, draft tube 2, escape pipe 3, wireway 4, electromagnetic screen net 5, anti-interference magnetic core 6, electromagnetic absorption plate 7.
Embodiment
See Fig. 1, the utility model relates to a kind of anti-interference anti-gas-leak gas meter, flow meter, comprise watchcase 1, draft tube 2 and escape pipe 3 is had in watchcase 1 outer setting, described watchcase 1 inside is provided with one section of wireway 4, wireway 4 adopts metal material to make and communicates with escape pipe 3, and described wireway 4 is integral type structure with watchcase 1.
Described watchcase 1 is made up of shell and inner casing, electromagnetic interference resistant device is provided with between described shell and inner casing, described electromagnetic interference resistant device comprises electromagnetic screen net 5, anti-interference magnetic core 6 and electromagnetic absorption plate 7, described electromagnetic interference resistant device 2 device is located between shell and inner casing, utilize electromagnetic interference resistant device 2 can efficiently by various blocking electromagnetic waves outside gas meter, flow meter, or to be absorbed.Described electromagnetic screen net 5 connected with outer casing, electromagnetic absorption plate 7 connects inner casing, and anti-interference magnetic core 6 is between electromagnetic screen net 5 and electromagnetic absorption plate 7.
