GASMETER WITH PREVENTING ECCENTRIC VALVE

The present invention relates to a gas meter having an opening and closing module for preventing eccentricity, which comprises: a housing wherein a compartment which is a storage space is provided; an inflow hole which is a channel through which gas can flow into the compartment while having an opening and closing end which is opened into the compartment; a discharging hole allowing the gas to be discharged from the compartment; and an opening and closing module having a planar plate which is disposed in the compartment to be reciprocally moved in the vertical direction and a compression pad for blocking inflow of the gas by coming in contact with the opening and closing end in accordance with the vertical reciprocate movement of the plate after being coupled to the plate, or for allowing the inflow of the gas by being spaced from the opening and closing end. Moreover, the compression pad has a guide surface of which a central portion facing the opening and closing end protrudes to enable thickness to be thinner from the central portion toward an outer side at a position which can be connected to the opening and closing end, thereby forming a gradient. 본 발명의 편심방지 개폐모듈이 구비된 가스계량기는 내측에 수용공간인 격실이 구비되는 하우징, 격실로 가스가 유입되는 통로로서 격실 내부로 개방된 개폐단을 지닌 유입구, 격실로부터 가스가 배출되는 배출구 및 격실 내부에 구비되어 직선왕복운동하는 판상의 플레이트, 플레이트에 결합되고 플레이트의 직선왕복운동에 따라서 개폐단에 접하여 가스의 유입을 차단하거나 개폐단과 이격되어 가스의 유입을 개방하는 압착패드가 구비된 개폐모듈을 포함하고, 압착패드는 개폐단과 마주보는 면의 중심부가 돌출되어 형성되고 개폐단과 접하는 위치에서 중심부로부터 외측으로 갈수록 그 두께가 감소하여 경사가 형성되는 가이드면이 구비된다.
