Claim Text:
1. An air discharge valve, comprising: a pipe connection base comprising at least one pipe member which includes an orifice; a rotary member axially connected with the pipe connection base, the rotary member being rotatable relative to the pipe connection base about a rotation axis and having at least one operational part; at least one seal member connected with the rotary member and corresponding to the orifice; and a buffer member axially connected with the pipe connection base, the buffer member being corresponded to the pipe connection base and driving the rotary member to rotate about the rotation axis, the buffer member comprising at least one corresponding operational part, the corresponding operational part being spaced apart from the operational part by a rotation buffering space to regulate the buffer member driving the rotation of the rotary member about the rotation axis; wherein the rotary member comprises a receiving chamber for receiving the buffer member, and wherein the at least one operational part is disposed in the receiving chamber; wherein the seal member correspondingly closes the orifice when the rotary member is arranged at a first orientation relative to the pipe connection base, and wherein the seal member is removed from the orifice when the rotary member is driven by the buffer member and rotated to a second orientation relative to the pipe connection base such that air from the pipe member is discharged from the orifice.
