Abstract
An air discharge valve comprises a pipe connection base, a rotary member, at least one seal member and a buffer member. The pipe connection base comprises at least one pipe member which comprises an orifice; the rotary member and the buffer member are both axially connected with the pipe connection base to rotate about a rotation axis relative to the pipe connection base; the rotary member comprises at least one operational part, and the at least one seal member is connected with the rotary member and corresponded to the orifice; the buffer member comprises at least one corresponding operational part, and a rotation buffering space is reserved between each corresponding operational part and each operational part. When the rotary member is at a first orientation relative to the pipe connection base, each seal member correspondingly seals and closes each orifice; when the rotary member is driven by the buffer member and rotated to a second orientation relative to the pipe connection base, each seal member is removed from each orifice so that air in each pipe member can be discharged from the corresponding orifice.
