Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of self-sealing air path separation, and particularly relates to a self-sealing air path separation mechanism. BACKGROUND

[0002] Air path separation refers to connecting and disconnecting a pipeline in a gas pipeline system, and automatically sealing two ends of the pipeline when disconnected to prevent gas leakage or pollution, and is commonly used in occasions where pneumatic components need to be frequently replaced or maintained, such as pneumatic tools, medical equipment, industrial automation, etc. The core lies in designing a delicate sealing mechanism and a connection mode to ensure the reliability of the connection and the airtightness when separated.

[0003] A self-sealing air path separation mechanism is disclosed in the utility model with the publication number CN209487841U, which comprises a guide sleeve and a shell. The shell is movably connected in the guide sleeve. The guide sleeve comprises a top rod fixedly connected in the guide sleeve and a push sleeve movably connected in the guide sleeve. A spring is arranged between the push sleeve and the top rod. A first sealing ring is arranged between the top rod and the push sleeve. A second sealing ring is arranged between the push sleeve and the guide sleeve. A third sealing ring is arranged between the shell and the guide sleeve. The utility model has the advantages that the first sealing ring, the second sealing ring and the third sealing ring can realize sealing of the butt joint part. In a vibrating environment, even if axial displacement occurs between the joint, the sealing ring can still be in good contact with the inner wall or the outer surface of the joint, so that the influence of vibration and uneven force on the sealing performance of the joint can be eliminated.

[0004] However, it is found in actual use that: the device is installed on the socket by the guide sleeve, and the shell is installed on the plug. When the shell pushes the push sleeve to compress the spring, the top rod penetrates into the shell to realize the air path, and when separated, the push sleeve is reset by the spring force to realize the air path sealing.

[0005] However, the push sleeve in the guide sleeve can move to guide the air path under the pushing of the shell, but the gas in the guide sleeve and the shell can only flow in one direction, i.e. from the guide sleeve to the shell, which limits the bidirectional flow of the gas, making the gas unable to circulate or alternately enter and exit, and reducing the versatility and adaptability. A self-sealing air path separation mechanism is provided. CONTENT OF THE UTILITY MODEL
