| description | The utility model provides a device for preventing combustible gas from flowing back to a pipeline, which belongs to the technical field of rotary kilns and comprises a regulating valve, and one end of the regulating valve is connected with a quick-break valve through a flange plate. The end, away from the adjusting valve, of the quick-break valve is connected with the flow meter through a flange plate. The flow meter is further connected with a check valve through a flange plate, when high-pressure gas appears at the end of the combustor, the high-pressure gas in the combustor can enter the gas flowing cavity along the gas flow channel, and when the high-pressure gas flows into the arc-shaped cavity in the gas flowing cavity, the sealing ball can be pushed to roll rightwards, and the gas inlet cavity is sealed. At the moment, the plunger loses the jacking force of the sealing ball, the plunger is jacked to move rightwards under the elastic force of the spring, and the conical surface at the right end of the |
