Description
Technical Field
The utility model belongs to the field of membrane type gas metering instruments, and particularly relates to an upper cover reinforcing structure of a membrane type gas metering instrument.
Background
The diaphragm gas meter mainly comprises a metering part (comprising two metering boxes respectively internally provided with flexible diaphragms), a transmission part (comprising a diaphragm plate, a folded plate, a vertical shaft, a rocker arm, a connecting rod, a crank, a shifting fork and a valve cover), a counting part and a shell, wherein the rest parts except the shell are collectively called as a core of the diaphragm gas meter. The working principle of the membrane type gas meter is as follows: a diaphragm (typically made of elastomer) is sealingly mounted at the centerline within each metering box and separates the interior of the metering box into two metering chambers. After entering the gas meter, the gas enters the two metering gas chambers of each metering box alternately, so that the diaphragm (and the diaphragm plate wrapped and clamped on the diaphragm) makes reciprocating motion, and then the linkage is realized, namely the diaphragm plate drives the folded plate (the outer end of the folded plate), the folded plate (the sleeve part at the inner side) drives the vertical shaft, the vertical shaft drives the rocker arm, the rocker arm drives the connecting rod, the connecting rod drives the crank, and the cam on the crank drives the shifting fork to make the valve cover make reciprocating motion on the valve grid and alternately open the gas inlets of the two metering gas chambers of each metering box (the reciprocating motion of the valve grid can make the gas enter the two metering gas chambers of each metering box alternately). Therefore, the gas in the volumes of the two metering boxes (four metering air chambers) can be discharged by one-time circulation, the crank rotates and drives the gear of the counter to rotate, and the counter displays the volume of the discharged gas.
At present, illegal gas stealing behaviors still exist, and after a thief detaches the membrane type gas meter, an object extends into the gas meter through the gas inlet of the gas meter to destroy or interfere transmission on the machine core, so that the metering of the membrane type gas meter is reduced, public property is destroyed, and illegal gas stealing is realized. And the top of the upper shell is easy to deform due to violent damage of a gas thief, so that the subsequent use safety is influenced.
Based on this, the applicant considers to design a membrane type gas metering instrument upper cover reinforcing structure capable of improving the structural strength of the upper cover.
