Abstract

A valve special for a gas meter is provided. The valve body is equipped with a stent, a supporting gear shaft, a duplex gear and a movable rack. The gear shaft is connected with an output shaft of a micro-motor. The output shaft is equipped with a gear, which meshes with the duplex gear. The duplex gear meshes with the movable rack. The movable rack can move up and down. The lower part of the movable rack is connected with a connecting bar, which is articulated with a valve. The valve is arranged on a valve hole. The valve hole is a gas channel. The periphery of the valve hole is equipped with a sealing ring. The invention can make the gas meter charge automatically, ensure the use precision of the gas meter and improve the surface life of the meter.

Description

technical field [0001] The invention relates to a special valve for a gas meter. Background technique [0002] At present, most of the existing civil gas meters use solenoid valves to control the gas supply, which is difficult to apply to industrial meters, and the cost is relatively high. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects and provide a special valve for gas meters. The technical scheme of the present invention is: a special valve for gas meter, characterized in that: a gear shaft 1 and a movable rack 7 are installed on the bracket of the valve body, a gear 2 is installed on the gear shaft 1, and a gear 2 is installed between the gear 2 and the rack 7. There are double gears, the rack 7 is equipped with a connecting rod, and the valve 9 is hinged on the connecting rod. The valve 9 is installed at the valve hole at the bottom of the valve body, and the gear shaft 1 is installed on the output sh...
