1. A valve for abnormal liquid, comprising:
a main body which includes a connecting part to be detachably mounted to a flow passageway of the abnormal liquid, and a passage communicating with the flow passageway of the abnormal liquid at the time of mounting; a valve chamber which is formed in the main body and has a hole corresponding to the passage; a valve body which is housed in the valve chamber and has a passage corresponding to the passage of the main body, the valve body performing switching operation by rotating with respect to the passage of the main body; a seal member which prevents the abnormal liquid that is present in the passage of the main body from entering the valve chamber when the passage of the valve body corresponds to the passage of the main body; a rotary shaft which is housed in the main body, the rotary shaft being connected to the valve body at least in a state where the abnormal liquid is not frozen, and being connected so as to be movable in an axial direction; an operating member which is connected to the rotary shaft in the main body and projects outside the main body, the operating member operating a rotation of the rotary shaft; and a bias member which biases the rotary shaft to a position of the valve body.
