Seem particularly urgent and needs.Current diaphragm gas meter structure existing at this stage is mainly by shell, diaphragm, valve seat, valve deck, transmission
The compositions such as mechanism.
Diaphragm gas meter belongs to a kind of displacement machine instrument, and metering system is formed by two containers (batch meter).Each
Container by concave diaphragm tabula among --- and by each container be divided into two can complementary shape measuring room.Motion of membrane pushes away
Power relies on the gas pressure difference of gas meter, flow meter import and export.Under the action of pressure difference, diaphragm generates continuous alternating movement, pushes away
Two groups of guiding valves are moved to arrange to outlet single metered volume (cycle volume) is constantly separated into full of the indoor combustion gas of metering, then
It is connected with counter by mechanical transmission mechanism, the counting to single metering volume is carried out, to measure the combustion gas for flowing through pipeline
Total amount.
But current diaphragm gas meter counter, complicated, occupied space is big.In addition, counter label is usually general
Logical white gravoply, with black engraved characters printing, without reflecting effect, under light condition deficiency and pitch-dark environment, even if being difficult to recognize using illumination
Counter signage content is read very inconvenient in actual use.Therefore, it is necessary to design a kind of new diaphragm gas meter counting
Device.
Utility model content
In view of the above-mentioned problems, the utility model is intended to provide a kind of diaphragm gas meter counter, to solve current counter
Complicated problem；Further solve the problems, such as that inconvenience uses in compared with dark situation.
The utility model provides a kind of diaphragm gas meter counter, and the counter includes counter-support, counter word
