摘要： The present invention provides a check valve for use in a vacuum sewage pipe. The check valve includes a body having a sewage inlet and a sewage outlet to be coupled to the vacuum sewage pipe, a flap valve element disposed in the body and rotatably supported by a first shaft, and a closing mechanism. The closing mechanism can keep the flap valve element in a closed state so as to allow the flap valve element to function as a gate valve. The closing mechanism can also limit an opening degree of the flap valve element so as to allow the flap valve element to function as a check valve.
