Pipelines are commonly used for the transport of liquids, gases or solid particles. The sealing gasket is the most common sealing device in various pipelines and is a sealing form with the simplest structure, the most convenient use and maintenance and the lowest cost. The gasket is typically manufactured from a relatively soft rubber, plastic or metal material. The gasket is generally clamped between the two pipe flanges by the action of bolts and the like, and the gap between the two pipe flanges is filled by the deformation of the gasket, so that the gasket plays a role in preventing various liquids, gases or solid particles from leaking.
Pipelines sometimes require one-way transportation or prevent backflow of liquid and gas, and in such cases, one-way control devices such as one-way valves are usually added to the pipelines. And the structure of one-way control devices such as one-way valves is more complex and the cost is higher.

The rigidity of the sealing gasket body is increased by the aid of the first flange, and the periphery of the inner hole of the second flange is 20-30mm larger than the inner hole of the sealing gasket body, so that the air door is convenient to mount and open.
In a preferred embodiment of the present invention, a ring of convex conical edge is disposed on the damper gasket and matches with the hole of the gasket body. The structure can improve the sealing effect of one-way control.
According to the preferred embodiment of the utility model, the air door is wrapped in the air door sealing gasket, so that the service life of the air door sealing gasket can be prolonged.
According to the preferred embodiment of the utility model, the periphery of the air door is 12-16mm larger than the inner hole of the sealing gasket body, so that the sealing effect of one-way control can be ensured.
According to the preferred embodiment of the utility model, the periphery of the air door is 10-12mm larger than the inner hole of the sealing gasket body, and when a circle of convex conical edge is arranged on the air door sealing gasket, the sealing effect of one-way control can be ensured.
