Limitation.
The flow-transfer of combustion gas is mainly mechanical movement by movement by diaphragm gas meter.Movement is mounted in shell, shell
It can play a protective role to movement.In measuring room of the combustion gas by movement, motion of membrane, the movement of diaphragm is driven to pass through transmission
Mechanism is changed into the rotary motion of transmission shaft.
As depicted in figs. 1 and 2, a kind of gas meter counting mechanism of the utility model embodiment offer, including driving gear 2,
Driven gear 3, sampling gear 4, shaft 5, sampling unit 6 and electronic counter（It is not shown in figure）.Pass through matching for all parts
It closes, counting mechanism realizes the counting to fuel flow rate.
The transmission shaft of movement passes through the shell 1 of gas meter, flow meter, driving gear 2 to be mounted on transmission shaft, driving gear 2 and transmission
Axis is concentric.When have combustion gas by when, the rotation of transmission shaft drives driving gear 2 to rotate.
Driven gear 3 is fixedly connected with sampling gear 4, and multiple fixed columns are arranged on driven gear 3, is sampled and is set on gear 4
The mounting hole coordinated with fixed column is set, fixed column is inserted into mounting hole so that driven gear 3 is fitted together with sampling gear 4.
Shaft 5 is fixed on the shell 1 of gas meter, flow meter, and driven gear 3 is rotatably mounted to sampling gear 4 in shaft 5.Driven gear
3 are located at the side of driving gear 2, and driving gear 2 is mediated with driven gear 3, and the rotation of driving gear 2 drives driven gear 3 to revolve
Turn, driven gear 3 drives sampling gear 4 to follow rotation.Thermosetting plastics making can be used in driving gear 2 and driven gear 3, adopts
Sample gear 4 and shaft 5 need to use metal material to make, and sample gear 4 and shaft 5 contacts, have the function of conduction.
Sampling unit 6 closely samples the installation of gear 4, and sampling unit 6 is located at the lower section for sampling gear 4 in the present embodiment.Such as
Shown in Fig. 3, sampling unit 6 includes fixed cylinder 61, gland 62, ball 63, resilient support 64, catch 65.
Fig. 3 A be gas meter, flow meter in use, sampling unit state diagram, fixed cylinder 61 be mounted on gas meter, flow meter shell 1 on, Gu
The shape of safety barrel 61 can be cuboid, be easily installed, the interior round cavity for being equipped with perforation, and the opening at the top of round cavity is
Necking.Ball 63 is mounted in the inner cavity of fixed cylinder, and 61 open-topped size of fixed cylinder is less than the diameter of ball 63, inner cavity
Diameter is more than the diameter of ball 63.Preferably, the diameter of inner cavity is bigger 0.5 ~ 2mm than the diameter of ball 63 so that ball 63 can be with
It moves freely, but not runs out from open top in the lumen.Gland 62 is fixed on the bottom of fixed cylinder 61, will be in fixed cylinder
The bottom lock of chamber avoids the component in fixed cylinder 61 from falling.Resilient support 64, elasticity are equipped between gland 62 and ball 63
One end of support 64 is contacted with gland 62, and the other end supports ball 63.Ball 63 is withstood on fixed cylinder by the elastic force of resilient support 64
61 top open part, i.e., when resilient support 64 is stretched over longest in fixed cylinder 61, ball 63 and the top of fixed cylinder 61 are opened
Mouth contact.Since open-topped limitation ball 63 will not all remove the inner cavity of fixed cylinder 61, but the top of ball 63 can dash forward
Go out the open top of fixed cylinder 61.So that ball 63 can move down when by external force, when not having external force, due to the work of elastic force
With ball 63 is returned to be contacted with open top.
When sampling the rotation of gear 4, the gear teeth of sampling gear 4 streak pressing ball 63, and a pressing is generated to ball 63
Power, that is, sample gear 4 the gear teeth can be come into full contact with ball 63, after the gear teeth streak, ball 63 bounces again, at this time ball 63 and
The gear teeth of sampling gear 4 do not contact.Sample the size in the gap on gear 4 between adjacent teeth, it is ensured that ball 63 is located at two
When between the gear teeth, do not contacted with sampling gear 4.
Gland 62, ball 63, resilient support 64 are both needed to be made by metal material, have the function of conduction.Gland 62 passes through
First conducting wire（It is not shown in figure）Electronic counter is connected, shaft 5 passes through the second conducting wire（It is not shown in figure）Connect electronic counting
Device.In this way, when sampling gear 4 and ball 63 contacts, the circuit connection of electronic counter generates an electric signal, electrometer
Number device realizes primary count.Sampling gear 4 is with ball 63 when not contacting, electronic counter then not counting.The meter of the present embodiment
The accurate metering to combustion gas can be realized in number mechanism, and can avoid magnetic disturbance problem, and counting mechanism is simple in structure, long lifespan.Electricity
Sub-count device is connected with display screen, and the dosage of combustion gas can inform user by display screen.
It as shown in Figure 3B, can be in fixed cylinder in order to avoid gas meter, flow meter generates counting if it is new not used gas meter, flow meter
One baffle 65 is installed on 61.Fixed cylinder 61 is equipped with the through-hole of installation baffle 65, and baffle 65 depresses ball 63 so that ball 63
Open top far from fixed cylinder, i.e. baffle 65 is located between 61 open top of fixed cylinder and ball 63, avoid ball 63 and
Sample the contact of gear 4.When needing using gas meter, flow meter, baffle 65 is extracted out, gas meter, flow meter can work, such simple in structure,
Facilitate easy to operate.
In the present embodiment, resilient support 64 is spring, other elastic parts, such as shrapnel also may be selected in designer, can
The supporting role of elasticity is played to ball.
Preferably, the open-topped edge 611 of fixed cylinder is tip-angled shape, and the edge of tip-angled shape can make 63 maximum limit of ball
The open top of the protrusion fixed cylinder of degree, avoids fixed cylinder influence of wall thickness, convenient for the contact of itself and sampling gear 4.Gland
Fit system between fixed cylinder is interference fit, facilitates installation, the mode of threaded connection, the utility model pair can also be used
This is not limited particularly.
The gas meter counting mechanism of the present embodiment further includes governor gear 8, governor gear 8 and mechanical counter（It is in figure
It shows）Connection can drive mechanical counter character wheel to rotate.Governor gear 8 is rotatably mounted on the shell 1 of gas meter, flow meter, with
Driving gear 2 is mediated.Driving gear 2 drives governor gear 8 to rotate, and governor gear 8 drives the character wheel rotation of mechanical counter, real
Now to the counting of burner flow.Governor gear 8 may include the different gear of multiple numbers of teeth, when needing to adjust to combustion gas Watch Error
When section, replaceable governor gear 8 by the proportioning of the different numbers of teeth, governing speed, and then reaches the mesh of adjustment combustion gas Watch Error
's.
In the present embodiment, counting mechanism is connect by the internal machine core with gas meter, flow meter, realizes the counting of combustion gas, in order to meter
Number mechanism is protected, and a upper cover 7 is arranged in the outside of counting mechanism, upper cover 7 covers counting mechanism, greatly improves combustion gas
The safety of table.
The counting mechanism of the gas meter, flow meter of the present embodiment includes electronic counting mode and mechanical count mode, and two ways is mutual
Comparison avoids a kind of counting mode when the error occurs, and the ignorant situation of user utilizes double count to ensure gas meter counting
