Novel diaphragm gas meter movement structure

Abstract

The invention relates to the field of metering instruments, and particularly discloses a novel diaphragm gas meter movement structure, which comprises a movement body, a metering shell and a supporting structure used for supporting the movement body, wherein the supporting structure comprises two brackets detachably arranged on the two short edges of the movement body respectively, supporting positions are arranged on the brackets and located on the two long edges of the movement body, and supporting rib positions for limiting the movement body to move along the long edges of the movement bodyare arranged on the two short edges of the movement body on the bracket. According to the invention, four-point support at four corners is adopted, so that the movement is supported more reliably, and the movement can be prevented from inclining in all directions; and gaps on the left side and the right side of an original movement body are eliminated through the supporting rib positions on the side faces, so that the movement body is prevented from shaking leftwards and rightwards when impacted.

Description

technical field [0001] The invention belongs to the technical field of measuring instruments, and in particular relates to a novel diaphragm gas meter movement structure. Background technique [0002] With the increasing demand for gas consumption in modern society and the increase in the volume of gas transactions, the demand for gas meters is also increasing. Membrane gas meter is a volumetric flowmeter with a large amount of use and a wide range of applications. It has a history of nearly 200 years and has been passed down and improved by several generations. It has been widely used up to now. Membrane gas meters play an important role in gas measurement and settlement, and their measurement accuracy and stability directly affect the fairness of trade settlement. [0003] The movement of the diaphragm gas meter is the core component of the metering, which is mainly composed of the following three parts: (1) Metering system: There are two basically the same metering chamb...

Problems solved by technology

However, the existing clip structure of the movement body cannot completely limit the displacement of the movement group in all directions, resulting in the movement group being skewed when the movement group is impacted

[0006] In addition, for the mechanical temperature compensation membrane gas meter, our company found during the production test that the key dimensions of the movement components are affected by the temperature, which affects the high and low temperature of the mechanical temperature compensation base meter to a certain extent.
