Embodiment Construction

[0022] With reference to the accompanying drawings, the gas meter chamber cover welding and fixing device is used to weld the connection structure between the chamber cover 8 and the core body 7, so as to realize the stable connection of the chamber cover 8 to the core body 7. The gas meter includes a core body 7, which is an integrally formed piece of plastic material. Two separate distribution chambers are formed in the core body 7 , one distribution chamber has an opening, and the two openings face opposite sides of the core body 7 respectively. A chamber cover 8 is provided at the opening of the dispensing chamber so that the dispensing chamber is hermetically sealed. The distribution chamber has an air inlet and an air outlet. The gas enters the distribution chamber from the inlet and enters the outlet pipe from the outlet. When the gas flows through the distribution chamber, it will push the valve in the distribution chamber to move. The valve passes through the transmis...

Abstract

The invention discloses a welding fixing device of a gas meter room cover. The welding fixing device is used for welding fixing of the room cover on a movement body. According to the technical measure, in the welding fixing device of the gas meter room cover, a gas meter comprises the movement body, two separated distribution rooms are arranged in the movement body, and the room cover is arrangedon openings of the distribution rooms. The welding fixing device is characterized in that multiple connecting columns are integrally formed in the positions, at the positions of opening edges of the distribution rooms, of the movement body, the connecting columns penetrate through connecting holes in the room cover and stretch to the outer side, the welding device is used for welding the ends of the connecting columns from the side face of the movement body, and then the room cover is connected and fixed to the movement body.

Description

technical field [0001] The invention relates to a welding device, in particular to a device for welding and fixing a chamber cover on a gas meter. 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. The two distribution chambers face the opposite sides of the core body. The outside is open, therefore, a chamber cover needs to be provided to close the opening to form a closed chamber. A valve is arranged in the distributing chamber, and the valve is connected with a toggle protruding into the distributing chamber. When the gas meter is measuring 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 th...
