Combustible gas pressure regulating valve stroke indicator

The utility model provides a combustible gas pressure regulating valve stroke indicator, which belongs to the technical field of combustible gas pressure regulating valves, and comprises a base provided with a pointer hole; the observation window is connected with the base to form an observation cavity, the observation window is provided with an observation hole, and the observation cavity is communicated with the outside through the observation hole; the glass tube is arranged in the observation cavity and connected with the base, the glass tube is provided with a pointer cavity and a closed part, and the pointer cavity is communicated with the pointer hole and is separated from the observation cavity through the closed part. The beneficial effects of the utility model are that the friction between the pointer and the O-shaped ring of the base may cause the excessive wear of the inner side of the pointer, so that the gas leaks into the pointer cavity, and the pointer cavity is communicated with the pointer h
