Equipment for assembling front valve and rear valve of mechanism of diaphragm gas meter

Abstract

The invention provides equipment for assembling a front valve and a rear valve of a mechanism of a diaphragm gas meter, and belongs to the technical field of gas meters. The equipment comprises a base, a press-fit mechanism and a slipping mechanism, the press-fit mechanism is installed to the base, and the output end of the press-fit mechanism can slide in a reciprocating mode relative to the base in the direction perpendicular to the base; the slipping mechanism is installed to the base and provided with a spacer, and the slipping mechanism can slide relative to the base towards the press-fit mechanism to enable the spacer to be located below the output end of the press-fit mechanism; a positioning assembly used for fixing a mechanism assembly of the gas meter is installed on the slipping mechanism. The equipment for assembling the front valve and the rear valve is convenient and rapid to operate; in the use process, the spacer can be conveniently arranged below the front valve and the rear valve, a gland and a vertical shaft can be installed on the mechanism of the gas meter simultaneously, installation is more convenient, the time and labor are saved during operation, and the installation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gas meters, in particular to a device for assembling front and rear flags of a diaphragm gas meter movement. Background technique [0002] When installing the membrane gas meter, the front and rear flags of the gas meter need to be installed on both sides of the gas meter core respectively. The existing assembly method is divided into three parts. The first part is to assemble the front and rear flags into the bellows respectively, and insert the vertical shaft; the second part is to use gaskets to raise the front and rear flags, and press the vertical shaft in place on the press-fitting device; the third part is to press-fit The sealing ring gland on the vertical shaft in place is pressed tightly. [0003] The inventor found in the research that there are at least the following problems in the installation process of the front and rear flags of the membrane gas meter in the prior art: [0004] First, t...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a device for assembling the front and rear flags of the diaphragm gas meter core, so as to improve the problems of complex operation, large installation errors and low efficiency when installing the front and rear flags of the gas meter in the prior art.
