Detailed Description

The invention is further described with reference to the following figures and specific examples.

The embodiment adopts the mode that two civil gas meter cores are combined, the requirement of the diaphragm gas meter metering core for industrial and commercial use is met, the product structure is simple, the size is small, the comprehensive cost is low, the purposes of cost reduction and efficiency improvement are achieved, and the competitiveness of the product in the market is powerfully improved. The concrete description is as follows:

maximum flow rate of 10m³The structure of the industrial and commercial diaphragm gas meter movement is shown in figure 1:

the structure is as follows: as shown in figure 1, the industrial and commercial gas meter is composed of two civil gas meter cores 1, a connecting rod 2, a gas outlet header pipe 3 and the like.

The structure is integrally strip-shaped, and compared with a single industrial and commercial gas meter core, the gas meter core has the characteristics of flattening and small volume, and is convenient for actual installation; meanwhile, the structure is simplified, the material is saved, and the requirements of product design, environmental protection and sustainable development are met. Meanwhile, the movement uses the same movement as a civil gas meter, the reuse rate of parts reaches more than 95%, independent purchase and management are not needed, and the comprehensive cost of the parts is low.
