The invention provides a device for detecting valve opening in-place of a gas meter based on the photoelectric reflection technology, and relates to the technical field of gas meters. The device comprises a reducer tank body and a tank cover which are tightly connected to form a cavity structure, wherein a fixed station with a bulged inner wall is arranged on the tank cover; a light absorption chamber is formed by the fixed station, the tank cover and the reducer tank body; a guide sleeve is connected with the side wall of the reducer tank body, and is movably connected with a valve rod; the valve rod is positioned between the fixed station and the bottom plate of the reducer tank body; and the fixed station is connected with a photoelectric transceiver. The device can be used for solving the technical problem of detection failure caused by an unreliable gas meter valve-opening-in-place signal detection mechanism in the prior art, and has the beneficial effect of accurate and reliable gas meter valve-opening-
