Embodiment approach

[0039] combinefigure 1 , image 3 and Figure 4 Therefore, the membrane structure of the present invention includes a membrane 1 , parallel plates 2 and clamping plates 3 respectively arranged on both sides of the membrane 1 and fixedly connected with the membrane 1 . According to an embodiment of the present invention, the parallel plate 2 is a double-sided galvanized plate, the sandwich plate 3 is a plastic material plate, and the diaphragm 1 is made of polyester fiber + NBR material. The sandwich plate 3, the diaphragm 1 and the parallel plate 2 are welded and connected to ensure that the parallel plate 2, the diaphragm 1 and the sandwich plate 3 are connected and fixed without falling off, and the durability and stable operation of the diaphragm structure of the present invention are improved sex.

[0040] It should be noted that, for the polyester fiber+NBR material of the diaphragm 1 of the present invention, the diaphragm 1 has no rigidity and can be bent in any direc...

Abstract

The invention relates to a diaphragm assembly, which comprises a diaphragm structure and a transmission part connected with the diaphragm structure and used for driving the diaphragm structure to move, the transmission part comprises a transmission shaft and a connecting plate connected to the transmission shaft, and the connecting plate comprises a first part and a second part which are connectedin sequence, the second part and the first part are obliquely arranged, and limiting columns are symmetrically arranged at the tail end of the second part in the width direction of the second part; positioning sliding tables are symmetrically arranged on the side, facing the diaphragm structure, of the second part in the width direction of the second part, and the diaphragm structure comprises boss sliding ways which are symmetrically arranged and matched with the positioning sliding tables. According to the diaphragm assembly, through cooperation of the positioning sliding tables and the boss sliding ways, when the transmission part drives the diaphragm structure, a certain guiding effect is achieved, meanwhile, it can be guaranteed that the transmission part stably transmits power to the diaphragm structure, periodic and stable movement of the diaphragm structure is guaranteed, and then the precision of an assembled gas meter can be guaranteed.

Description

technical field [0001] The invention relates to the field of gas meters, in particular to a diaphragm assembly. Background technique [0002] Diaphragm structure is an important component in the gas meter, and its quality will directly affect the performance of the gas meter. The diaphragm is usually made of soft rubber material without rigidity, so it is necessary to set up a reinforcing plate to ensure that it can move back and forth periodically in the diaphragm chamber, so as to ensure that the diaphragm does not deform during each movement, resulting in inconsistent air intake and outlet each time . [0003] However, the stability of the driving connection between the existing driving member for driving the diaphragm and the diaphragm cannot guarantee the stability during the movement of the diaphragm, because the accuracy of the final gas meter is poor. On the other hand, the unreasonable structure of the existing diaphragm will also lead to poor stability of movemen...
