A cylinder cover seat ring airtightness detection device belongs to the technical field of engine production. A to-be-detected cylinder cover is fixedly placed on a table top of the machine body frame, a valve pressing mechanism is arranged at the upper end of the machine body frame and matched with the upper end of the to-be-detected cylinder cover, and a valve guide pipe blocking mechanism is arranged at the lower end of the machine body frame and matched with the lower end of the to-be-detected cylinder cover. The air inlet side of the cylinder cover to be detected is provided with a plugging inflation mechanism. The device is low in manufacturing cost and strong in adaptability, truly simulates an assembled engine cylinder cover valve, detects the matching quality of the cylinder cover seat ring and the valve after processing, and prevents bad parts of the cylinder cover seat ring from flowing out. Meanwhile, the tool machining quality can be effectively judged, and effective help is provided for prolongi
