Abstract

The invention discloses a safety valve installed in an intelligent gas meter and integrated with a brushless gear motor in a fastened mode. The valve is driven by the brushless gear motor free from electric sparks, and the brushless gear motor free from the electric sparks is tightly sealed. The valve is installed at the air inlet end or the air outlet end of a ventilation path in the gas meter. An original control method, original use conditions and an original drive circuit are not changed basically, an original installation position is not changed either, and possible potential safety hazards caused by brush sparks of the motor are eliminated under the condition that an original opening / closing control function is guaranteed.

Description

technical field [0001] The invention relates to a valve for controlling fluid, in particular to an electric valve that can be conveniently installed on the ventilation path of an intelligent gas meter. Gas: Since the gas meter is full of combustible gas, the electric valve installed in the gas meter has the first priority for gas safety. For this reason, a safety valve driven by a motor without electric brushes and without electric sparks during operation must be used. Background technique [0002] At the present stage, the installation of valves in gas meters known to public use is a historical necessity of the invention, use and development of gas meters. The invention of the gas meter is exactly the actual needs of people adapting to gas usage billing. At present, in order to improve management efficiency, cancel manual meter reading, cancel manual data collection, and adapt to the requirements of computer data management, the gas company adopts computerized management c...
