Description

Gas meter smooth in operation

Technical Field

The utility model belongs to the gas table field relates to a gas table that moves smoothly.

Background

At present, in a diaphragm gas meter, combustible gas enters a metering chamber from a gas inlet through a gas gate valve, and drives a linkage mechanism and a counting mechanism to operate, so that the diaphragm gas meter performs volume metering. The gas meter comprises a metering cavity, a rocker, a membrane assembly, a gas outlet, a gas inlet, a gas outlet, a gas inlet hole, a gas outlet hole and a gas outlet hole.

However, in the working process of the gas meter, when the rocker moves to the farthest end, the shell may be blocked, so that the gas meter cannot return in time. Or the gas meter is in a balanced state, so that the gas meter is blocked and cannot be started.

Disclosure of Invention

The utility model aims at providing a gas table that moves smoothly to the above-mentioned problem that exists among the prior art.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a smooth gas table of operation, its characterized in that, includes the gas table body, the measurement cavity has been seted up to the inside of gas table body, the measurement cavity in be provided with the involucra, the measurement cavity in still be provided with pivot and rocker, the involucra be used for driving the rocker and revolve around the rotation of axes, the pivot on be connected with metering device, the pivot wear to be equipped with the elastic component, elastic component one end and rocker connect, the elastic component other end and the interior wall connection of measurement cavity.

The utility model discloses a theory of operation: when the gas table during operation, gaseous entering measures the cavity, because gaseous entering, the involucra drives the rocker and revolves the rotation of axes, measure the gaseous volume grow in the cavity, the rocker moves the farthest end, at this moment, because elastic component one end is connected on the rocker, one end is connected on the inner wall of measuring the cavity, the process that the rocker removed is exactly the process of elastic component compression, when the rocker moves the farthest end, the elastic component is because the compression produces the resilience force, and the rocker receives the resilience force, there is the trend of back movement. Therefore, the defect that the rocker cannot return in time due to the fact that the rocker is blocked when moving to the farthest end is overcome.

In the gas meter which runs smoothly, the elastic part is a torsion spring.

In the gas meter smooth in operation, the rocker and the inner wall of the metering chamber are provided with clamping holes, and two ends of the elastic piece are clamped with the clamping holes.

In the gas meter which runs smoothly, two ends of the elastic piece are hook-shaped.

In the gas meter smooth in operation, the rocker is provided with a rotating shaft channel, and the rotating shaft is positioned in the rotating shaft channel.

Compared with the prior art, the utility model has the advantages of it is following:

1. the utility model discloses because the rocker receives the resilience force, can not block the shell.

2. The utility model discloses the inner wall of rocker and measurement cavity all is provided with the card hole, the both ends and the card hole joint of elastic component. The two ends of the elastic piece are hook-shaped. The both ends firm in connection that collude the form just can dismantle the connection, convenient change.
