Embodiment
The utility model proposes a kind of temperature compensation gas meter, be intended to solve existing gas meter and can't make the unified mutually problem that relates to of actual metered and standard environment metering.
The utlity model has and vary with temperature automatic correction gas measurement function.The technical scheme that the utility model proposed is particularly useful for deaphragm gas meter.
This temperature compensation gas meter, comprise big pull bar, lower link bar, vertical shaft, epithelium, big pull bar is connected with vertical shaft, and vertical shaft is connected with epithelium through flap, connect thrermostatic bimetal-plate (big rob support) by attachment screw on the big pull bar, this big rob support is connected with the lower link bar pin through adjuster bar.Symmetrical lower link bar is connected with central shaft through crank.
Described big pull bar is horizontally disposed, and big rob support arranges vertically and be fixed together with big pull bar that the end of lower link bar is provided with pin-and-hole, and described adjuster bar is through in the pin-and-hole and with big rob support and is threaded.
Described adjuster bar is provided with spacing point, i.e. the mobile starting point of lower link bar, and the effect of this point is to be provided with the initial position of thrermostatic bimetal-plate distortion.
Now principle of work of the present utility model is explained as follows:
This product is by install big rob support additional on its big pull bar by common gas meter, big rob support varies with temperature and produces displacement, change the position of the adjusting lever on this support, thereby change the epithelium revolution volume of gas meter movement, realize what metering was revised automatically with variation of temperature.
Big rob support adopts thermal bimetal material to make.Thermal bimetal material has with variation of temperature and produces diastrophic characteristics, because adorning big rob support is fixed on the big pull bar, when big rob support varies with temperature generation flexural deformation, will cause the adjuster bar on the big rob support to change the position, produce displacement.
The utility model can be on the basis of former deaphragm gas meter reload temperature compensation system (being big rob support, adjuster bar), its profile still can keep the profile of former deaphragm gas meter.
Design concept is as follows:
Coal gas is a kind of combustible gas, and the environment temperature at the variation of its volume and gas place, environmental pressure, ambient atmosphere pressure all have direct internal relation.Its formula is: P
1V
1/ T
1=P
2V
2/ T
2Suppose to be designated as 1 representative standard conditions down, be designated as 2 the residing physical environment of representative gas meter down, the assumed stress condition is identical simultaneously, and then formula becomes V
1/ T
1=V
2/ T
2, so temperature and volume are in linear relation.By the temperature automatically correcting device, the metering of gas meter can be adapted to the metering of standard state.
The temperature automatically correcting device adopts thrermostatic bimetal-plate material (big rob support), because thermo bimetal's sheet material has the advantages that to occur bending and deformation with variation of ambient temperature, utilize these characteristics to realize the variation of relative length between adjuster bar and vertical shaft, reach the variation that changes the big pull bar anglec of rotation, thereby change the variation of parallel-plate displacement, change the size of gas meter revolution volume.
Deaphragm gas meter is to enter by the inlet of coal gas from gas meter, and from exporting outflow, the movement that promotes gas meter by the pressure differential that passes in and out gas moves, and by the transmission of the gearing between the movement sum counter, the motion realization of drive counter is counted.
The movement motion of gas meter is in the indoor continuous turnover of the capsule of gas meter by coal gas, drive parallel-plate and epithelium to-and-fro movement, because parallel-plate is connected with flap, flap is connected with vertical shaft, vertical shaft is connected with big railing, big pull bar is connected with big rob support, and big rob support is connected with adjuster bar, and adjuster bar is connected with lower link bar, lower link bar is connected with crank, crank is connected with axis, and whole device adopts symmetrical structure, thereby the operation of realization mechanism and metering.
Whether the metering of gas meter is correct and adjustable, is closely related at the indoor volume of capsule by epithelium, and the size of this volume is decided by that lower link bar is relevant with the inflection point of crank length of run and big pull bar.
As shown in the figure, the skew of big draw rod positions will cause adjusting screw relatively and the length distance of vertical shaft.Because the distance of crank and lower link bar is constant, so lower link bar will cause big pull bar to change around the anglec of rotation of vertical shaft in the variation of adjuster bar top offset, thereby cause the anglec of rotation of flap around vertical shaft, cause that flap drives the move distance of parallel-plate.Because the shift length of parallel-plate changes the variation that causes epithelium revolution volume.
The revolution volume of gas meter is the basis and the core of gas meter, the variation of revolution volume will cause the variation of measuring, cause is in different atmospheric environment conditions, the counting assembly of gas meter and other gear train do not change, so the variation of gas meter revolution volume is reflected on the counting assembly and just changes.
By above variation, realize the purpose that metering is revised.
