Abstract

The invention relates to the field of gas meters, and particularly discloses a small magnetic transmission structure of a diaphragm gas meter. The small magnetic transmission structure comprises a sealing gasket, a shaft sleeve, an outer magnetic set and an inner magnetic set, the inner magnetic set is located on the inner side of the shaft sleeve, the outer magnetic set is located on the outer side of the shaft sleeve, the outer magnetic set comprises a first outer magnetic sleeve, a second outer magnetic sleeve and an outer magnet, the outer magnet is an annular cylinder, and the first outer magnetic sleeve and the second outer magnetic sleeve are respectively clamped at two ends of the outer magnet; the inner magnetic set comprises a first inner magnetic sleeve, a second inner magnetic sleeve and an inner magnet, the inner magnet is also an annular cylinder, and the first inner magnetic sleeve and the second inner magnetic sleeve are clamped to the two ends of the inner magnet respectively; and the outer magnet is made of a ferrite material, and the inner magnet is made of a neodymium iron boron material with stronger magnetic force. The magnetic transmission structure with the inner magnet made of the neodymium iron boron and the outer magnet still made of the ferrite material is adopted, the torque required by magnetic transmission and the transmission space requirement of the small diaphragm gas meter can be met, the ferrite material is reserved in the outer magnet, and the material cost of the outer magnet can be reduced by reducing the size of the outer magnet.

Description

technical field [0001] The invention belongs to the technical field of gas meters, and in particular relates to a small magnetic transmission structure of a membrane gas meter. Background technique [0002] The flow range of G2.5 membrane gas meter is 0.025~4m 3 / h is the most widely used model at home and abroad, accounting for more than 60% of the entire membrane gas meter usage. Metering movements that meet G2.5 gas meters have a rotary volume of 1.2L, 0.8L and smaller, and the most used is the movement with a rotary volume of 1.2L, which is compatible with G1.6, G2.5 and G4 Three models, the maximum flow rate can reach 6m 3 / h; rotary volume 0.8L movement gas meter is compatible with G1.6 and G2.5 models, the maximum flow rate can reach 4m 3 / h. The G2.5 gas meter is designed with a movement volume of 0.8L, and its volume is smaller than that of 1.2L, which can better reduce material consumption, reduce packaging, transportation and storage costs, and be more competi...
