Description
Technical field
The utility model is related to gas meter, flow meter technical field, more particularly to a kind of gas meter, flow meter temperature compensation mechanism.
Background technology
Diaphragm gas meter is a kind of gas consumption measuring instrument, and gas meter, flow meter does periodicity work using the motion on movement
Make.Require that the gas volume of each work period discharge is certain when gas meter, flow meter is measured, so could statistical metering.But combustion gas
Volume is varied with temperature and changed, the gaseous mass of gas meter, flow meter discharge it is certain and under temperature different situations, according to gaseous state side
Journey (P0V0/T0=P1V1/T1) know, its volume of the gas of the same race of discharge phase homogenous quantities is different under uniform pressure different temperatures
, the gas volume of temperature reduction phase homogenous quantities will reduce, and the relative density of gas will increase；Temperature raises phase homogenous quantities
Gas volume will expand, the relative density of gas will reduce, and combustion gas is to use volume metering in reality, with seasonal variations temperature
The area that differs greatly is spent, its combustion gas variable density is big, causes the metering difference of Various Seasonal under combustion gas use condition same case,
This is accomplished by being converted at same temperature and volume metering is carried out to combustion gas just has reference role, the benchmark temperature of China's gas metering
It is (20 ± 2) DEG C to spend, i other words the gas volume discharged within the unit interval using gas meter, flow meter at (20 ± 2) DEG C is used as reference value,
The gas volume for wanting to make gas meter, flow meter be measured within the unit interval under any temperature in certain operating temperature range is converted to benchmark
At a temperature of when be consistent substantially, the revolution volume of gas meter, flow meter is changed using the change of throw of crankshaft.
Existing diaphragm gas meter can not be fully compensated influence of the temperature change to metering performance, be fired when temperature change is big
Gas meter metering occurs precision severe deviations, influences normal gas consumption valuation.
Utility model content
Technical problem to be solved in the utility model and the technical assignment for proposing are that prior art is improved, there is provided
A kind of gas meter, flow meter temperature compensation mechanism, solves gas meter, flow meter occur because temperature change causes combustion gas variable density in current technology
The larger problem of measurement deviation.
To solve above technical problem, the technical solution of the utility model is：
A kind of gas meter, flow meter temperature compensation mechanism, including crank disc and crank-pin, it is characterised in that filled on described crank disc
Put temperature-sensitive bag, the push rod telescopic direction of temperature-sensitive bag along crank disc surface, the push rod of temperature-sensitive bag is connected to crank-pin, and bent
The temperature-compensating slide that handle pin is set along crank disc.Gas meter, flow meter temperature compensation mechanism described in the utility model is using sense
Thermometer bulb realizes temperature-compensating, and temperature-sensitive bag its push rod in temperature change can stretch, and drives crank-pin to move using push rod
So as to regulating gas table throw of crankshaft, and then change gas meter, flow meter revolution volume, be finally reached the purpose of temperature-compensating, temperature-sensitive
The induction sensitivity of bag, temperature control stability are good, can be with temperature real-time change so as to adjust amount of temperature compensation, temperature in real time
Compensation chute defines the moving range of crank-pin, more accurately changes throw of crankshaft, improves the accuracy of temperature-compensating.
Further, described temperature-sensitive bag on crank disc, can easily adjust temperature-sensitive bag by slide mechanism device
Initial position, so as to adjust initial position of the crank-pin in normal temperature, improves the accuracy of temperature-compensating.
Further, described slide mechanism includes position adjustable board and the initial bit chute being arranged on crank disc, temperature-sensitive bag
On position adjustable board, position adjustable board is along initial bit slide and fixes, and simple structure is easy to adjust for device.
Further, described temperature-sensitive bag is hinged on position adjustable board, and when the push rod of temperature-sensitive bag is flexible, temperature-sensitive bag can edge
Pin joint is rotated, so that crank-pin can smoothly along temperature-compensating slide.
Further, described crank disc is provided with screw body and drives position adjustable board along initial bit slide, regulation side
Just, and the initial position of temperature-sensitive bag can easily be fixed, using simple.
Compared with prior art, the utility model advantage is：
When ambient temperature changes, temperature-sensitive band moves crank to gas meter, flow meter temperature compensation mechanism described in the utility model
Axle movement changes throw of crankshaft, so as to change the open and close time of the movement travel of epithelium and valve during metering, reaches
The purpose of temperature-compensating, improves the metering accuracy of gas meter, flow meter；And the utility model simple structure, regulation that can be convenient, flexible
Initial position of the crank axle in normal temperature, ensures measuring accuracy.
