Gas meter toggle joint transmission device

Abstract

The invention discloses a gas meter toggle joint transmission device and solves a problem that after a temperature compensation device is arranged on an existing gas meter, unsmooth transmission is easy to cause so as to generate a new error. The adopted technical measure is that the gas meter toggle joint transmission device comprises an intermediate gear; the intermediate gear is rotationally arranged on a machine core body of a gas meter; the intermediate gear is in transmission connection with a counting device; a connection pillar is eccentrically arranged on the intermediate gear; the connection pillar is in transmission connection with the upper end side of a toggle joint by a connection rod; and the gas meter toggle joint transmission device is characterized in that the connectionpillar is movably arranged on the intermediate gear, and a temperature sensing device is used for sensing an environment temperature so as to carry out adaptive change on a radial position of the connection pillar on the intermediate gear, so that the connection pillar is away from the axis of the intermediate gear at a high temperature and is close to the axis of the intermediate gear at a low temperature.

Description

technical field [0001] The invention relates to a gas meter for measuring the gas flow, in particular to a device on the gas meter for realizing transmission between a toggle and an intermediate gear. Background technique [0002] The gas meter is used to measure the flow of gas. The main structure of the gas meter is the core body. There are two distribution chambers separated from each other in the core body. A valve is arranged in the distribution chamber. The valve and the valve extend into the distribution chamber. Indoor toggle joints. When the gas meter measures the gas, after the gas enters the core body from the air inlet, the gas pushes the valve to move towards the direction of emptying the distribution chamber, and the gas flows out from the gas outlet connected to the distribution chamber and enters the user pipeline. When the gas enters the distribution chamber, it will push the valve to move, and the valve will be transmitted to the valve in another distribut...

Problems solved by technology

And this kind of lever-type transmission mechanism has relatively high requirements on the position of the transmission parts, otherwise it will cause the transmission to get stuck, which in turn will affect the accuracy of the gas meter for the measurement of the medium gas.

Since temperature changes will cause changes in the radian of the bimetal sheet, the bimetal sheet will change the spatial position of the large tie rod bracket, which makes the transmission smoothness of the metering transmission device on this gas meter poor. On the one hand, it will affect the air intake of the gas meter. smoothness, on the other hand, it will also cause new measurement errors in the gas meter
